Change the formula from quorum update on vote period to participation EMA (exponential moving average). Current quorum storage is removed and new storage participation EMA is introduced. Minimum and maximum quorum caps are added to the constants of the economic protocol. Whenever a voting period would cause the quorum to go below or above the caps it will be bound to the limit defined in the constants. In the future token holders can easily modify the caps by changing the constants. Third party developers should make sure they can parse the new fields in the `/constants` RPC, or at least ignore them. --- .../lib_protocol/alpha_context.mli | 8 ++++- src/proto_alpha/lib_protocol/amendment.ml | 33 +++++++++++-------- .../lib_protocol/constants_repr.ml | 18 +++++++--- .../lib_protocol/constants_storage.ml | 6 ++++ src/proto_alpha/lib_protocol/storage.ml | 4 +-- src/proto_alpha/lib_protocol/storage.mli | 4 +-- src/proto_alpha/lib_protocol/vote_storage.ml | 17 +++++++--- src/proto_alpha/lib_protocol/vote_storage.mli | 4 ++- 8 files changed, 66 insertions(+), 28 deletions(-) diff --git a/src/proto_alpha/lib_protocol/alpha_context.mli b/src/proto_alpha/lib_protocol/alpha_context.mli index 62d317621334..f49b685eb811 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.mli +++ b/src/proto_alpha/lib_protocol/alpha_context.mli @@ -380,6 +380,8 @@ module Constants : sig cost_per_byte: Tez.t ; hard_storage_limit_per_operation: Z.t ; test_chain_duration: int64; + quorum_min: int32 ; + quorum_max: int32 ; } val parametric_encoding: parametric Data_encoding.t val parametric: context -> parametric @@ -404,6 +406,8 @@ module Constants : sig val block_security_deposit: context -> Tez.t val endorsement_security_deposit: context -> Tez.t val test_chain_duration: context -> int64 + val quorum_min: context -> int32 + val quorum_max: context -> int32 (** All constants: fixed and parametric *) type t = { @@ -775,7 +779,9 @@ module Vote : sig context -> Voting_period.kind -> context tzresult Lwt.t val get_current_quorum: context -> int32 tzresult Lwt.t - val set_current_quorum: context -> int32 -> context tzresult Lwt.t + + val get_participation_ema: context -> int32 tzresult Lwt.t + val set_participation_ema: context -> int32 -> context tzresult Lwt.t val get_current_proposal: context -> proposal tzresult Lwt.t diff --git a/src/proto_alpha/lib_protocol/amendment.ml b/src/proto_alpha/lib_protocol/amendment.ml index ec30af1105dd..7c3b5b5e5c5f 100644 --- a/src/proto_alpha/lib_protocol/amendment.ml +++ b/src/proto_alpha/lib_protocol/amendment.ml @@ -47,13 +47,15 @@ let select_winning_proposal proposals = the current quorum.

A block is now valid only if its timestamp has a minimal delay with respect to the previous block's timestamp, and this minimal delay depends not only on the block's priority but also on the number of endorsement operations included in the block. In Emmy+, blocks' fitness increases by one unit with each level. In this way, Emmy+ simplifies the optimal baking strategy: The bakers used to have to choose whether to wait for more endorsements to include in their block, or to publish the block immediately, without waiting. The incentive for including more endorsements was to increase the fitness and win against unknown blocks. However, when a block was produced too late in the priority period, there was the risk that the block did not reach endorsers before the block of next priority. In Emmy+, the baker does not need to take such a decision, because the baker cannot publish a block too early. Third party developers should make sure they can parse the new fields in the `/constants` RPC, or at least ignore them. --- src/proto_alpha/lib_protocol/alpha_context.ml | 1 + .../lib_protocol/alpha_context.mli | 7 +++ src/proto_alpha/lib_protocol/apply.ml | 55 ++++++++++++++++--- src/proto_alpha/lib_protocol/baking.ml | 46 +++++++++++++--- src/proto_alpha/lib_protocol/baking.mli | 38 ++++++++++++- .../lib_protocol/constants_repr.ml | 20 +++++-- .../lib_protocol/constants_storage.ml | 6 ++ src/proto_alpha/lib_protocol/main.ml | 30 ++++++---- src/proto_alpha/lib_protocol/main.mli | 3 + src/proto_alpha/lib_protocol/raw_context.ml | 5 ++ src/proto_alpha/lib_protocol/raw_context.mli | 3 + src/proto_alpha/lib_protocol/time_repr.ml | 20 ++++++- src/proto_alpha/lib_protocol/time_repr.mli | 1 + 13 files changed, 202 insertions(+), 33 deletions(-) diff --git a/src/proto_alpha/lib_protocol/alpha_context.ml b/src/proto_alpha/lib_protocol/alpha_context.ml index 435d9920ecb8..09dcebb54a4d 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.ml +++ b/src/proto_alpha/lib_protocol/alpha_context.ml @@ -169,6 +169,7 @@ let fork_test_chain = Raw_context.fork_test_chain let record_endorsement = Raw_context.record_endorsement let allowed_endorsements = Raw_context.allowed_endorsements let init_endorsements = Raw_context.init_endorsements +let included_endorsements = Raw_context.included_endorsements let reset_internal_nonce = Raw_context.reset_internal_nonce let fresh_internal_nonce = Raw_context.fresh_internal_nonce diff --git a/src/proto_alpha/lib_protocol/alpha_context.mli b/src/proto_alpha/lib_protocol/alpha_context.mli index f49b685eb811..c504a3d9e6e6 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.mli +++ b/src/proto_alpha/lib_protocol/alpha_context.mli @@ -81,6 +81,7 @@ module Timestamp : sig include BASIC_DATA with type t = Time.t type time = t val (+?) : time -> Period.t -> time tzresult + val (-?) : time -> time -> Period.t tzresult val of_notation: string -> time option val to_notation: time -> string @@ -382,6 +383,8 @@ module Constants : sig test_chain_duration: int64; quorum_min: int32 ; quorum_max: int32 ; + initial_endorsers: int ; + delay_per_missing_endorsement : Period.t ; } val parametric_encoding: parametric Data_encoding.t val parametric: context -> parametric @@ -392,6 +395,8 @@ module Constants : sig val blocks_per_voting_period: context -> int32 val time_between_blocks: context -> Period.t list val endorsers_per_block: context -> int + val initial_endorsers: context -> int + val delay_per_missing_endorsement: context -> Period.t val hard_gas_limit_per_operation: context -> Z.t val hard_gas_limit_per_block: context -> Z.t val cost_per_byte: context -> Tez.t @@ -1152,6 +1157,8 @@ val init_endorsements: context -> (Signature.Public_key.t * int list * bool) Signature.Public_key_hash.Map.t -> context +val included_endorsements: + context -> int val reset_internal_nonce: context -> context val fresh_internal_nonce: context -> (context * int) tzresult diff --git a/src/proto_alpha/lib_protocol/apply.ml b/src/proto_alpha/lib_protocol/apply.ml index 984d1fee67f7..d4b1ff251a2a 100644 --- a/src/proto_alpha/lib_protocol/apply.ml +++ b/src/proto_alpha/lib_protocol/apply.ml @@ -60,6 +60,12 @@ type error += Outdated_double_baking_evidence type error += Invalid_activation of { pkh : Ed25519.Public_key_hash.t } type error += Multiple_revelation type error += Gas_quota_exceeded_init_deserialize (* Permanent *) +type error += + Not_enough_endorsements_for_priority of + { required : int ; + priority : int ; + endorsements : int ; + timestamp: Time.t } let () = register_error_kind @@ -372,7 +378,28 @@ let () = parse within the provided gas bounds."

Implicit accounts (tz1, tz2, tz3) can directly set their delegate. Furthermore implicit accounts have the ability to delete their delegate by sending a "delegate" transaction with an empty delegate field. This specific patch does not impact the ability for originated (KT1) accounts to set or delete their delegate. The storage type of the "Delegated" accounts changes it's index from "Contract_hash" to "Contract_repr.Index". This change in the type signature allows that both implicit and originated accounts can be stored in the set. Explorers and wallets should handle the delegation from tz1, tz2 and tz3 accounts. RPC `/context/delegates//delegated_contracts` (and composite RPC `/context/delegates//`) can now contain tz1, tz2 and tz3 addresses. --- .../lib_protocol/alpha_context.mli | 2 +- .../lib_protocol/delegate_services.ml | 6 +- .../lib_protocol/delegate_services.mli | 4 +- .../lib_protocol/delegate_storage.ml | 81 +++++++++++-------- .../lib_protocol/delegate_storage.mli | 6 +- src/proto_alpha/lib_protocol/storage.ml | 2 +- src/proto_alpha/lib_protocol/storage.mli | 3 +- 7 files changed, 60 insertions(+), 44 deletions(-) diff --git a/src/proto_alpha/lib_protocol/alpha_context.mli b/src/proto_alpha/lib_protocol/alpha_context.mli index d730a2dc3ac4..3dc5027c1cf7 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.mli +++ b/src/proto_alpha/lib_protocol/alpha_context.mli @@ -724,7 +724,7 @@ module Delegate : sig val delegated_contracts: context -> Signature.Public_key_hash.t -> - Contract_hash.t list Lwt.t + Contract_repr.t list Lwt.t val delegated_balance: context -> Signature.Public_key_hash.t -> diff --git a/src/proto_alpha/lib_protocol/delegate_services.ml b/src/proto_alpha/lib_protocol/delegate_services.ml index 88d6547c791f..bbaa282609bb 100644 --- a/src/proto_alpha/lib_protocol/delegate_services.ml +++ b/src/proto_alpha/lib_protocol/delegate_services.ml @@ -30,7 +30,7 @@ type info = { frozen_balance: Tez.t ; frozen_balance_by_cycle: Delegate.frozen_balance Cycle.Map.t ; staking_balance: Tez.t ; - delegated_contracts: Contract_hash.t list ; + delegated_contracts: Contract_repr.t list ; delegated_balance: Tez.t ; deactivated: bool ; grace_period: Cycle.t ; @@ -56,7 +56,7 @@ let info_encoding = (req "frozen_balance" Tez.encoding) (req "frozen_balance_by_cycle" Delegate.frozen_balance_by_cycle_encoding) (req "staking_balance" Tez.encoding) - (req "delegated_contracts" (list Contract_hash.encoding)) + (req "delegated_contracts" (list Contract_repr.encoding)) (req "delegated_balance" Tez.encoding) (req "deactivated" bool) (req "grace_period" Cycle.encoding)) @@ -140,7 +140,7 @@ module S = struct ~description: "Returns the list of contracts that delegate to a given delegate." ~query: RPC_query.empty - ~output: (list Contract_hash.encoding) + ~output: (list Contract_repr.encoding) RPC_path.(path / "delegated_contracts") let delegated_balance = diff --git a/src/proto_alpha/lib_protocol/delegate_services.mli b/src/proto_alpha/lib_protocol/delegate_services.mli index 64384463d3a9..74b282b98b32 100644 --- a/src/proto_alpha/lib_protocol/delegate_services.mli +++ b/src/proto_alpha/lib_protocol/delegate_services.mli @@ -36,7 +36,7 @@ type info = { frozen_balance: Tez.t ; frozen_balance_by_cycle: Delegate.frozen_balance Cycle.Map.t ; staking_balance: Tez.t ; - delegated_contracts: Contract_hash.t list ; + delegated_contracts: Contract_repr.t list ; delegated_balance: Tez.t ; deactivated: bool ; grace_period: Cycle.t ; @@ -72,7 +72,7 @@ val staking_balance: val delegated_contracts: 'a #RPC_context.simple -> 'a -> Signature.Public_key_hash.t -> - Contract_hash.t list shell_tzresult Lwt.t + Contract_repr.t list shell_tzresult Lwt.t val delegated_balance: 'a #RPC_context.simple -> 'a -> diff --git a/src/proto_alpha/lib_protocol/delegate_storage.ml b/src/proto_alpha/lib_protocol/delegate_storage.ml index da097d9d6f3b..b6df55ad7ede 100644 --- a/src/proto_alpha/lib_protocol/delegate_storage.ml +++ b/src/proto_alpha/lib_protocol/delegate_storage.ml @@ -215,30 +215,26 @@ let () = let is_delegatable c contract = match Contract_repr.is_implicit contract with | Some _ -> - return_false + (* Implicit contracts are delegatable *) + return_true | None -> Storage.Contract.Delegatable.mem c contract >>= return -let link c contract delegate balance = +let link c contract delegate = + Storage.Contract.Balance.get c contract >>=?

In Athens and before, Michelson contracts could store typed handles to contracts in their storage or in constants in the code. This meant that typechecking a contract required accessing other contracts from the chain context. This extra type safety was not worth the engineering cost for tooling and high level languages. Contracts will now have to store values of type `address` and use the `CONTRACT` instruction to typecheck contract references on demand. All existing contracts that used the feature will continue to work as-is. This is done by introducing a `legacy` flag througout the typechecking code, with the following trivial semantics: - everything already in the chain is considered `legacy` and can use deprecated features, - everything added to the chain (parameters of transactions and code and storage of originations cannot. Smart contract developers should adapt their code to store `address`es and use instruction `CONTRACT`. --- src/proto_alpha/lib_protocol/apply.ml | 2 +- .../lib_protocol/contract_services.ml | 8 +- .../lib_protocol/helpers_services.ml | 4 +- src/proto_alpha/lib_protocol/main.ml | 2 +- .../lib_protocol/script_interpreter.ml | 6 +- .../lib_protocol/script_ir_translator.ml | 208 ++++++++++-------- .../lib_protocol/script_ir_translator.mli | 10 +- src/proto_alpha/lib_protocol/script_repr.ml | 2 +- .../lib_protocol/script_tc_errors.ml | 1 + .../script_tc_errors_registration.ml | 16 +- 10 files changed, 149 insertions(+), 110 deletions(-) diff --git a/src/proto_alpha/lib_protocol/apply.ml b/src/proto_alpha/lib_protocol/apply.ml index 80d510ab4fc2..3de8022d23ae 100644 --- a/src/proto_alpha/lib_protocol/apply.ml +++ b/src/proto_alpha/lib_protocol/apply.ml @@ -526,7 +526,7 @@ let apply_manager_operation_content : Lwt.return (Gas.consume ctxt (Script.deserialized_cost unparsed_storage)) >>=?

This patch implements a way for a transaction to target a specific code path of a smart contract using a name. The implementation is piggy baking on Michelson's or type and field annotations. To take advantage of the multiple entrypoint feature, the parameter type of a contract must have at its toplevel a tree of `or` types. At each branching point in this tree, a field annotation (the ones with a %) can appear, providing the name of the entrypoint. Transactions now have to specify an entrypoint name. When a transaction is executed, the appropriate `Left` and `Right` constructors are automatically added to the value that is pushed onto the input stack, depending on the position of the entrypoint in the parameter type tree. This way, two contracts who share an entrypoint of the same type under the same name can be called exactly the same, even if the entrypoint is placed at a different point in their parameter type tree. From inside the smart contract, nothing changes. From within Michelson, this feature is also available. The `contract t` type now points to a specific entrypoint (of type `t`) of the contract. For this, the `CONTRACT` and `SELF` instructions now take an optional annotation (set to `%default` if not passed). The `TRANSFER_TOKEN` instruction will then use the entrypoint from the `contract t` value that it consumes from the stack. An exception to the semantics is made for the `%default` entrypoint : if present in the contract, it behaves as any other, however if not present, default is automatically attributed to the root of the parameter type. A special check is made at origination that there is no two entrypoints with the same name, and that if a default is present somewhere, then all entrypoints must be named, as otherwise some parts of the code would be unreachable. Smart contract developers can already use the feature, and their contracts will automatically take advantage of entrypoints after the migration. Smart contract developers should take great care when deploying contracts that use the `CREATE_CONTRACT` instruction, as this instruction will produce a failing operation after the migration if it tries to deploy a contract with ill formed entrypoints. To prevent this, contract authors should test their contract in a sandbox with the new protocol, or simply avoid hardcoding the `CREATE_CONTRACT` instruction when possible. --- .../lib_protocol/alpha_context.mli | 5 +- src/proto_alpha/lib_protocol/apply.ml | 53 ++- .../lib_protocol/helpers_services.ml | 29 +- .../lib_protocol/helpers_services.mli | 5 +- .../lib_protocol/michelson_v1_gas.mli | 2 +- .../lib_protocol/operation_repr.ml | 33 +- .../lib_protocol/operation_repr.mli | 3 +- .../lib_protocol/script_interpreter.ml | 62 +-- .../lib_protocol/script_interpreter.mli | 2 + .../lib_protocol/script_ir_annot.ml | 31 +- .../lib_protocol/script_ir_annot.mli | 6 + .../lib_protocol/script_ir_translator.ml | 377 +++++++++++++----- .../lib_protocol/script_ir_translator.mli | 10 +- src/proto_alpha/lib_protocol/script_repr.ml | 13 + src/proto_alpha/lib_protocol/script_repr.mli | 4 + .../lib_protocol/script_tc_errors.ml | 4 + .../script_tc_errors_registration.ml | 46 ++- .../lib_protocol/script_typed_ir.ml | 30 +- 18 files changed, 521 insertions(+), 194 deletions(-) diff --git a/src/proto_alpha/lib_protocol/alpha_context.mli b/src/proto_alpha/lib_protocol/alpha_context.mli index 2f42a7c8e0e6..52c0942bb16e 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.mli +++ b/src/proto_alpha/lib_protocol/alpha_context.mli @@ -339,6 +339,8 @@ module Script : sig val minimal_deserialize_cost : lazy_expr -> Gas.cost val force_decode : context -> lazy_expr -> (expr * context) tzresult Lwt.t val force_bytes : context -> lazy_expr -> (MBytes.t * context) tzresult Lwt.t + + val unit_parameter : lazy_expr end module Constants : sig @@ -921,7 +923,8 @@ and _ manager_operation = | Reveal : Signature.Public_key.t -> Kind.reveal manager_operation | Transaction : { amount: Tez.tez ; -

Smart contract authors should stop putting field annotations on their option types, or their contract will not be deployable after the migration.

Some instructions were missing consistency checks on the annotations of their arguments. For instance, it was possible to `CONS` a value of type `unit :A` on a `list (unit :B)`. Smart contracts already deployed before the migration will continue to work even if they present such issues. However, smart contract authors should already make sure that their annotations are consistent by using the new typechecker in a sandbox. This is even more recommended for contracts deployed before the migration that use the `CREATE_CONTRACT` instruction. If the code they deploy is ill-annotated according to the new stricter rule, these contracts will produce failing operations after the migration. --- .../lib_protocol/script_interpreter.ml | 3 +- .../lib_protocol/script_ir_annot.ml | 32 +- .../lib_protocol/script_ir_annot.mli | 13 +- .../lib_protocol/script_ir_translator.ml | 344 ++++++++++-------- .../lib_protocol/script_ir_translator.mli | 4 +- 5 files changed, 216 insertions(+), 180 deletions(-) diff --git a/src/proto_alpha/lib_protocol/script_interpreter.ml b/src/proto_alpha/lib_protocol/script_interpreter.ml index 00292652606d..42f3d72d78f0 100644 --- a/src/proto_alpha/lib_protocol/script_interpreter.ml +++ b/src/proto_alpha/lib_protocol/script_interpreter.ml @@ -737,7 +737,8 @@ let rec interp Lwt.return (Gas.consume ctxt Interp_costs.contract) >>=? fun ctxt -> begin match contract, entrypoint with | (contract, "default"), entrypoint | (contract, entrypoint), "default" -> - Script_ir_translator.parse_contract_for_script ctxt loc t contract ~entrypoint >>=? fun (ctxt, maybe_contract) -> + Script_ir_translator.parse_contract_for_script + ~legacy:false ctxt loc t contract ~entrypoint >>=? fun (ctxt, maybe_contract) -> logged_return (Item (maybe_contract, rest), ctxt) | _ -> logged_return (Item (None, rest), ctxt) end diff --git a/src/proto_alpha/lib_protocol/script_ir_annot.ml b/src/proto_alpha/lib_protocol/script_ir_annot.ml index 9e684421a41b..33660d98e1f2 100644 --- a/src/proto_alpha/lib_protocol/script_ir_annot.ml +++ b/src/proto_alpha/lib_protocol/script_ir_annot.ml @@ -101,26 +101,26 @@ let gen_access_annot Some (`Var_annot (String.concat "."

This is a change required by the switch to Emmy+, in which a baker could decide after having forged a block to include a late endorsement and update the timestamp to an earlier point. With the current semantics of `NOW`, this would mean reevaluating all operations to make sure they are still valid everytime such a change is decided. This patch prevents that issue by fixing the timestamp seen by Michelson independently of the number of endorsements. --- src/proto_alpha/lib_protocol/alpha_context.ml | 13 ++++++++++--- src/proto_alpha/lib_protocol/alpha_context.mli | 1 + src/proto_alpha/lib_protocol/init_storage.ml | 4 ++-- src/proto_alpha/lib_protocol/main.ml | 11 +++++------ src/proto_alpha/lib_protocol/raw_context.ml | 7 +++++-- src/proto_alpha/lib_protocol/raw_context.mli | 2 ++ .../lib_protocol/services_registration.ml | 6 +++++- src/proto_alpha/lib_protocol/test/rolls.ml | 2 ++ 8 files changed, 32 insertions(+), 14 deletions(-) diff --git a/src/proto_alpha/lib_protocol/alpha_context.ml b/src/proto_alpha/lib_protocol/alpha_context.ml index 10d0accf5b5e..5e4d2d97aacb 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.ml +++ b/src/proto_alpha/lib_protocol/alpha_context.ml @@ -62,9 +62,16 @@ module Script_int = Script_int_repr module Script_timestamp = struct include Script_timestamp_repr let now ctxt = - Raw_context.current_timestamp ctxt - |> Timestamp.to_seconds - |> of_int64 + let { Constants_repr.time_between_blocks ; _ } = + Raw_context.constants ctxt in + match time_between_blocks with + | [] -> failwith "Internal error: 'time_between_block' constants \ + is an empty list." + | first_delay :: _ -> + let current_timestamp = Raw_context.predecessor_timestamp ctxt in + Time.add current_timestamp (Period_repr.to_seconds first_delay) + |> Timestamp.to_seconds + |> of_int64 end module Script = struct include Michelson_v1_primitives diff --git a/src/proto_alpha/lib_protocol/alpha_context.mli b/src/proto_alpha/lib_protocol/alpha_context.mli index 52c0942bb16e..457ed0618235 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.mli +++ b/src/proto_alpha/lib_protocol/alpha_context.mli @@ -1148,6 +1148,7 @@ val prepare_first_block: val prepare: Context.t -> level:Int32.t -> + predecessor_timestamp:Time.t -> timestamp:Time.t -> fitness:Fitness.t -> context tzresult Lwt.t diff --git a/src/proto_alpha/lib_protocol/init_storage.ml b/src/proto_alpha/lib_protocol/init_storage.ml index 16773e013171..c3affbfc6634 100644 --- a/src/proto_alpha/lib_protocol/init_storage.ml +++ b/src/proto_alpha/lib_protocol/init_storage.ml @@ -87,5 +87,5 @@ let prepare_first_block ctxt ~typecheck ~level ~timestamp ~fitness = >>=?

Spendable and delegatable flags are simulated by adding entrypoints to a scripted contract. --- .../lib_protocol/.ocamlformat-ignore | 2 + src/proto_alpha/lib_protocol/TEZOS_PROTOCOL | 1 + src/proto_alpha/lib_protocol/alpha_context.ml | 1 + .../lib_protocol/alpha_context.mli | 15 + src/proto_alpha/lib_protocol/dune.inc | 8 +- .../legacy_script_support_repr.ml | 481 ++++++++++++++++++ .../legacy_script_support_repr.mli | 58 +++ 7 files changed, 562 insertions(+), 4 deletions(-) create mode 100644 src/proto_alpha/lib_protocol/legacy_script_support_repr.ml create mode 100644 src/proto_alpha/lib_protocol/legacy_script_support_repr.mli diff --git a/src/proto_alpha/lib_protocol/.ocamlformat-ignore b/src/proto_alpha/lib_protocol/.ocamlformat-ignore index 638f36536584..260409bcad38 100644 --- a/src/proto_alpha/lib_protocol/.ocamlformat-ignore +++ b/src/proto_alpha/lib_protocol/.ocamlformat-ignore @@ -45,6 +45,8 @@ gas_limit_repr.mli helpers_services.ml helpers_services.mli init_storage.ml +legacy_script_support_repr.ml +legacy_script_support_repr.mli level_repr.ml level_repr.mli level_storage.ml diff --git a/src/proto_alpha/lib_protocol/TEZOS_PROTOCOL b/src/proto_alpha/lib_protocol/TEZOS_PROTOCOL index 227ece362d97..bede80027363 100644 --- a/src/proto_alpha/lib_protocol/TEZOS_PROTOCOL +++ b/src/proto_alpha/lib_protocol/TEZOS_PROTOCOL @@ -25,6 +25,7 @@ "Script_timestamp_repr", "Michelson_v1_primitives", "Script_repr", + "Legacy_script_support_repr", "Contract_repr", "Roll_repr", "Vote_repr", diff --git a/src/proto_alpha/lib_protocol/alpha_context.ml b/src/proto_alpha/lib_protocol/alpha_context.ml index 5e4d2d97aacb..4a184292617f 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.ml +++ b/src/proto_alpha/lib_protocol/alpha_context.ml @@ -86,6 +86,7 @@ module Script = struct (Script_repr.force_bytes lexpr >>? fun (b, cost) -> Raw_context.consume_gas ctxt cost >|? fun ctxt -> (b, ctxt)) + module Legacy_support = Legacy_script_support_repr end module Fees = Fees_storage diff --git a/src/proto_alpha/lib_protocol/alpha_context.mli b/src/proto_alpha/lib_protocol/alpha_context.mli index 87d8573d726b..5639a1410fe7 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.mli +++ b/src/proto_alpha/lib_protocol/alpha_context.mli @@ -344,6 +344,21 @@ module Script : sig val force_bytes : context -> lazy_expr -> (MBytes.t * context) tzresult Lwt.t val unit_parameter : lazy_expr + + module Legacy_support : sig + val manager_script_code: lazy_expr + val add_do: + manager_pkh: Signature.Public_key_hash.t -> + script_code: lazy_expr -> + script_storage: lazy_expr -> + (lazy_expr * lazy_expr) tzresult Lwt.t + val add_set_delegate: + manager_pkh: Signature.Public_key_hash.t -> + script_code: lazy_expr -> + script_storage: lazy_expr -> + (lazy_expr * lazy_expr) tzresult Lwt.t + end + end module Constants : sig diff --git a/src/proto_alpha/lib_protocol/dune.inc b/src/proto_alpha/lib_protocol/dune.inc index f7bbe11361d9..7d293d021848 100644 --- a/src/proto_alpha/lib_protocol/dune.inc +++ b/src/proto_alpha/lib_protocol/dune.inc @@ -18,7 +18,7 @@ module CamlinternalFormatBasics = struct include CamlinternalFormatBasics end (rule (targets registerer.ml) -

All spendable, scriptless contracts are migrated to 'manager.tz' script. Contracts that have a spendable flag set are augmented with a `%do` entrypoint. Contracts that have a delegatable flag set are augmented with `%set_delegate` and `%remove_delegate` entrypoints. Interacting with converted contracts must now be done via smart contract calls. As an example, here is how `tezos-client` handles retro-compatibility for the `transfer` and `set delegate` commands. When crafting a transaction, if the source is a KT1, if checks that its storage is either of type `key_hash` or `pair key_hash _`, and retrieve this `key_hash`. Let's name this `key_hash` . To implement `tezos-client set delegate for to `, it starts by looking for entrypoints. If `%set_delegate` is present, it does the equivalent of 'tezos-client transfer 0 from to \ --entrypoint 'set_delegate' --arg '' where is the key_hash found in the contract's storage If `%do` is present, it does the equivalent of 'tezos-client transfer 0 from to \ --entrypoint 'do' \ --arg '{ NIL operation ; \ PUSH key_hash ; \ SOME ; \ SET_DELEGATE ; \ CONS }' where is the key_hash found in the contract's storage To implement `tezos-client transfer from to `, when the destination is a simple adress or a contract of type `unit`, it does the equivalent of ``` tezos-client transfer 0 from to \ --entrypoint "do" \ --arg '{ NIL operation ; \ PUSH address ; \ CONTRACT unit; AMOUNT ; \ UNIT ; \ TRANSFER_TOKENS ; \ CONS ; \ PAIR }' ``` To implement `tezos-client transfer from to \ [--arg ] [--entrypoint ]`, it starts by checking that the contract has a `%do` entrypoint. Then it look for type `` of contract `` in the chain And it does the equivalent of ``` tezos-client transfer 0 from to \ --entrypoint "do" \ --arg '{ NIL operation ; \ PUSH address ; \ CONTRACT % ; # Omit if not given AMOUNT ; \ PUSH ; \ # UNIT if not given TRANSFER_TOKENS ; \ CONS ; \ PAIR }' ``` --- src/proto_alpha/lib_protocol/init_storage.ml | 84 ++++++++++++++++++- src/proto_alpha/lib_protocol/storage.ml | 8 ++ src/proto_alpha/lib_protocol/storage.mli | 40 +++++++-- .../lib_protocol/storage_functors.ml | 15 ++++ src/proto_alpha/lib_protocol/storage_sigs.ml | 16 +++- 5 files changed, 152 insertions(+), 11 deletions(-) diff --git a/src/proto_alpha/lib_protocol/init_storage.ml b/src/proto_alpha/lib_protocol/init_storage.ml index c3affbfc6634..c22bb60f5782 100644 --- a/src/proto_alpha/lib_protocol/init_storage.ml +++ b/src/proto_alpha/lib_protocol/init_storage.ml @@ -52,8 +52,87 @@ let migrate_delegated ctxt contract = else return ctxt +let transform_script: + (manager_pkh: Signature.Public_key_hash.t -> + script_code: Script_repr.lazy_expr -> + script_storage: Script_repr.lazy_expr -> + (Script_repr.lazy_expr * Script_repr.lazy_expr) tzresult Lwt.t) -> + Raw_context.t -> + Contract_repr.t -> + Script_repr.lazy_expr -> + Raw_context.t tzresult Lwt.t = + fun transformation ctxt contract code -> + (* Get the manager of the originated contract *) + Contract_storage.get_manager ctxt contract >>=?

It removes the manager, spendable and delegatable flags and counter from all KT1s. It deprecates CREATE_ACCOUNT from use in new contracts, as well as the manager, spendable and delegatable arguments from CREATE_CONTRACT. Already deployed contracts with deprecated instructions will continue to work by using legacy support scripts (deploying `manager.tz` for `CREATE_ACCOUNT` and adding entrypoints for `CREATE_CONTRACT`). This change will impact all users of the RPC API as well as anyone who forges operations. The source of manager operations is now a tz1, tz2 or tz3, and no longer a KT1. The manager field and the spendable and delegatable flags disappear from the origination operation format (JSON and binary) as well as everywhere in the RPC API. --- .../lib_client/michelson_v1_error_reporter.ml | 7 ++ src/proto_alpha/lib_protocol/alpha_context.ml | 6 +- .../lib_protocol/alpha_context.mli | 37 ++---- src/proto_alpha/lib_protocol/apply.ml | 83 ++++--------- .../lib_protocol/bootstrap_storage.ml | 7 +- .../lib_protocol/contract_services.ml | 109 ++++++----------- .../lib_protocol/contract_services.mli | 19 +-- .../lib_protocol/contract_storage.ml | 110 ++++++++---------- .../lib_protocol/contract_storage.mli | 30 ++--- .../lib_protocol/delegate_storage.ml | 39 +------ .../lib_protocol/delegate_storage.mli | 19 +-- src/proto_alpha/lib_protocol/fees_storage.ml | 2 +- .../lib_protocol/helpers_services.ml | 22 ++-- .../lib_protocol/helpers_services.mli | 15 +-- src/proto_alpha/lib_protocol/init_storage.ml | 27 +++-- .../lib_protocol/michelson_v1_gas.ml | 6 + .../lib_protocol/operation_repr.ml | 27 ++--- .../lib_protocol/operation_repr.mli | 7 +- .../lib_protocol/script_interpreter.ml | 67 ++++++++--- .../lib_protocol/script_ir_translator.ml | 86 ++++++++++++-- .../lib_protocol/script_tc_errors.ml | 3 + .../script_tc_errors_registration.ml | 12 +- .../lib_protocol/script_typed_ir.ml | 2 + src/proto_alpha/lib_protocol/storage.ml | 10 +- src/proto_alpha/lib_protocol/storage.mli | 4 +- .../lib_protocol/storage_functors.ml | 7 +- .../lib_protocol/storage_functors.mli | 1 -

However, the implementation can actually push a negative number instead of -1 and a positive number instead of 1 depending on the type and values. This semantics should not break any code as the result of `COMPARE` is almost always comsumed by comparison projectors such as `GT` or `LT` who only care about the sign. However, for the sake of consistency, this patches makes `COMPARE` return only -1, 0 or 1.

This limitation also applies to `set`, `map` and `big_map` indexes. This is an issue in particular for `big_map`s that cannot be nested, because it prevents indexing data by a pair of indexes, such as a `key_hash` and a `string`. This patch lifts that restriction, allowing to compare `pair`s of values, as long as their left component remains a simple value, impicitly making comparable values right combs whose leaves are simple values. The ordering is naturally lexicographic. This patch also refactors a bit the comparison code to simplify it and reduce code duplication. --- .../lib_protocol/michelson_v1_gas.ml | 35 +++-- .../lib_protocol/michelson_v1_gas.mli | 10 +- .../lib_protocol/script_interpreter.ml | 32 +---- .../lib_protocol/script_ir_translator.ml | 123 ++++++++---------- .../lib_protocol/script_typed_ir.ml | 36 +++-- 5 files changed, 104 insertions(+), 132 deletions(-) diff --git a/src/proto_alpha/lib_protocol/michelson_v1_gas.ml b/src/proto_alpha/lib_protocol/michelson_v1_gas.ml index 7f517721b85a..19e7d6cb9b55 100644 --- a/src/proto_alpha/lib_protocol/michelson_v1_gas.ml +++ b/src/proto_alpha/lib_protocol/michelson_v1_gas.ml @@ -227,18 +227,31 @@ module Cost_of = struct let self = step_cost 1 let amount = step_cost 1 let chain_id = step_cost 1 - let compare_bool _ _ = step_cost 1 - let compare_string s1 s2 = - step_cost ((7 + Compare.Int.max (String.length s1) (String.length s2)) / 8) +@ step_cost 1 - let compare_bytes s1 s2 = - step_cost ((7 + Compare.Int.max (MBytes.length s1) (MBytes.length s2)) / 8) +@ step_cost 1 - let compare_tez _ _ = step_cost 1 let compare_zint n1 n2 = step_cost ((7 + Compare.Int.max (Z.numbits n1) (Z.numbits n2)) / 8) +@ step_cost 1 - let compare_int n1 n2 = compare_zint (Script_int.to_zint n1) (Script_int.to_zint n2) - let compare_nat = compare_int - let compare_key_hash _ _ = alloc_bytes_cost 36 - let compare_timestamp t1 t2 = compare_zint (Script_timestamp.to_zint t1) (Script_timestamp.to_zint t2) - let compare_address _ _ = step_cost 20 + let rec compare : type a s.

Rescaling step cost - Rescale step_cost by 2^7 to allow finer cost accounting in the interpeter. - Expose new function atomic_step_cost exposing finer resolution step increments. II. Provide facilities for interpreter-specific cost accounting Introduce new functions `Gas.incr_interpreter_cost` and `Gas.bill_interpreter_cost`. - The context stores a new counter 'interpreter_cost' of type Gas_limit_repr.cost - functions are provided to: - increment this counter (incr_interpreter_cost) and - bill for the gas corresponding to this counter and reset this counter. Until bill_interpreter_cost is called, the interpreter_cost is _not_ taken into account into the effectively consumed gas. - Each call to incr_interpreter_cost still checks that we are under the operation and block gas limits. - The interpreter uses these functions instead of the usual Gas.consume. The invariant that has to be respected for this to be transparent to the rest of the protocol is that all continuations of the `step` function to other functions should bill and reset the interpreter_cost beforehand. This concerns calls to interp, calls to the typechecker, calls to read from a big map, calls to the serialization/deserialization mechanism, etc; in short, all calls to other parts of the protocol should have a context in a state where this fine-grained gas bookkeeping has been settled and reset. --- .../lib_protocol/gas_limit_repr.ml | 97 +++++++++++++------ .../lib_protocol/gas_limit_repr.mli | 9 +- src/proto_alpha/lib_protocol/raw_context.ml | 16 ++- .../lib_protocol/script_interpreter.ml | 14 +-- 4 files changed, 91 insertions(+), 45 deletions(-) diff --git a/src/proto_alpha/lib_protocol/gas_limit_repr.ml b/src/proto_alpha/lib_protocol/gas_limit_repr.ml index 27025d7d6ab0..37e4de65f3a4 100644 --- a/src/proto_alpha/lib_protocol/gas_limit_repr.ml +++ b/src/proto_alpha/lib_protocol/gas_limit_repr.ml @@ -27,6 +27,8 @@ type t = | Unaccounted | Limited of { remaining : Z.t } +type internal_gas = Z.t + type cost = { allocations : Z.t ; steps : Z.t ; @@ -90,37 +92,60 @@ let write_base_weight = Z.of_int 160 let byte_read_weight = Z.of_int 10 let byte_written_weight = Z.of_int 15 -let consume block_gas operation_gas cost = match operation_gas with - | Unaccounted -> ok (block_gas, Unaccounted) +let rescaling_bits = 7 +let rescaling_mask = + Z.sub (Z.shift_left Z.one rescaling_bits) Z.one + +let scale (z : Z.t) = Z.shift_left z rescaling_bits +let rescale (z : Z.t) = Z.shift_right z rescaling_bits + +let cost_to_internal_gas (cost : cost) : internal_gas = + Z.add + (Z.add + (Z.mul cost.allocations allocation_weight) + (Z.mul cost.steps step_weight)) + (Z.add + (Z.add + (Z.mul cost.reads read_base_weight) + (Z.mul cost.writes write_base_weight)) + (Z.add + (Z.mul cost.bytes_read byte_read_weight) + (Z.mul cost.bytes_written byte_written_weight))) + +let internal_gas_to_gas internal_gas : Z.t * internal_gas = + let gas = rescale internal_gas in + let rest = Z.logand internal_gas rescaling_mask in + (gas, rest) + +let consume block_gas operation_gas internal_gas cost = + match operation_gas with + | Unaccounted -> ok (block_gas, Unaccounted, internal_gas) | Limited { remaining } -> - let weighted_cost = - Z.add - (Z.add - (Z.mul allocation_weight cost.allocations) - (Z.mul step_weight cost.steps)) - (Z.add - (Z.add - (Z.mul read_base_weight cost.reads) - (Z.mul write_base_weight cost.writes)) - (Z.add - (Z.mul byte_read_weight cost.bytes_read) - (Z.mul byte_written_weight cost.bytes_written))) in - let remaining = - Z.sub remaining weighted_cost in - let block_remaining = - Z.sub block_gas weighted_cost in - if Compare.Z.(remaining < Z.zero) - then error Operation_quota_exceeded - else if Compare.Z.(block_remaining < Z.zero) - then error Block_quota_exceeded - else ok (block_remaining, Limited { remaining }) - -let check_enough block_gas operation_gas cost = - consume block_gas operation_gas cost - >|?

Big maps can be transferred from a contract to another, either as parameter (transactions) or storage (originations). In this case, they are morally duplicated (as opposed to shared) from the contract point of view. In the implementation, sharing happens. Big maps can be created with `EMPTY_BIG_MAP t` and cleared on the fly. The big_map type still cannot appear as argument of big_map, PUSH or UNPACK. When you duplicate a big map, you are charged with the full storage cost. This patch moves the big maps outside of the contracts in the context, in their own prefix path and indexed by integers. Big_map literals in Michelson expressions are now either the same as maps or their integer index. A temporary zone is introduced, necessary to make sure that big_maps are not spuriously cleared or left dangling during big_map transfers in internal operations. These are represented by negative indexes, and don't persist. --- src/proto_alpha/lib_protocol/alpha_context.ml | 19 + .../lib_protocol/alpha_context.mli | 38 +- src/proto_alpha/lib_protocol/apply.ml | 17 +- src/proto_alpha/lib_protocol/apply_results.ml | 14 +- .../lib_protocol/apply_results.mli | 3 +- .../lib_protocol/contract_services.ml | 77 ++- .../lib_protocol/contract_services.mli | 8 +- .../lib_protocol/contract_storage.ml | 155 ++++- .../lib_protocol/contract_storage.mli | 27 +- src/proto_alpha/lib_protocol/init_storage.ml | 1 + src/proto_alpha/lib_protocol/main.ml | 11 +- .../lib_protocol/michelson_v1_gas.ml | 1 + .../lib_protocol/michelson_v1_primitives.ml | 4 + .../lib_protocol/michelson_v1_primitives.mli | 1 + src/proto_alpha/lib_protocol/raw_context.ml | 18 + src/proto_alpha/lib_protocol/raw_context.mli | 9 + .../lib_protocol/script_interpreter.ml | 74 ++- .../lib_protocol/script_ir_translator.ml | 602 ++++++++++++------ .../lib_protocol/script_ir_translator.mli | 28 +- src/proto_alpha/lib_protocol/script_repr.ml | 9 + src/proto_alpha/lib_protocol/script_repr.mli | 2 + .../lib_protocol/script_tc_errors.ml | 1 + .../script_tc_errors_registration.ml | 20 +- .../lib_protocol/script_typed_ir.ml | 40 +- src/proto_alpha/lib_protocol/storage.ml | 163 ++++- src/proto_alpha/lib_protocol/storage.mli | 42 +- .../lib_protocol/storage_functors.ml | 89 +-- src/proto_alpha/lib_protocol/storage_sigs.ml | 35 +- 28 files changed, 1098 insertions(+), 410 deletions(-) diff --git a/src/proto_alpha/lib_protocol/alpha_context.ml b/src/proto_alpha/lib_protocol/alpha_context.ml index c99eec570bb4..c5fd259f1e5b 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.ml +++ b/src/proto_alpha/lib_protocol/alpha_context.ml @@ -126,6 +126,25 @@ module Contract = struct let init_origination_nonce = Raw_context.init_origination_nonce let unset_origination_nonce = Raw_context.unset_origination_nonce end +module Big_map = struct + type id = Z.t + let fresh = Storage.Big_map.Next.incr + let fresh_temporary = Raw_context.fresh_temporary_big_map + let mem c m k = Storage.Big_map.Contents.mem (c, m) k + let get_opt c m k = Storage.Big_map.Contents.get_option (c, m) k + let rpc_arg = Storage.Big_map.rpc_arg + let cleanup_temporary c = + Raw_context.temporary_big_maps c Storage.Big_map.remove_rec c >>= fun c -> + Lwt.return (Raw_context.reset_temporary_big_map c) + let exists c id = + Lwt.return (Raw_context.consume_gas c (Gas_limit_repr.read_bytes_cost Z.zero)) >>=? fun c -> + Storage.Big_map.Key_type.get_option c id >>=? fun kt -> + match kt with + | None -> return (c, None) + | Some kt -> + Storage.Big_map.Value_type.get c id >>=? fun kv -> + return (c, Some (kt, kv)) +end module Delegate = Delegate_storage module Roll = struct include Roll_repr diff --git a/src/proto_alpha/lib_protocol/alpha_context.mli b/src/proto_alpha/lib_protocol/alpha_context.mli index 73123874dc88..c3ee807531bd 100644 --- a/src/proto_alpha/lib_protocol/alpha_context.mli +++ b/src/proto_alpha/lib_protocol/alpha_context.mli @@ -225,6 +225,7 @@ module Script : sig | I_DROP | I_DUP | I_EDIV + | I_EMPTY_BIG_MAP | I_EMPTY_MAP | I_EMPTY_SET | I_EQ @@ -571,6 +572,17 @@ module Seed : sig end +module Big_map: sig + type id = Z.t + val fresh : context -> (context * id) tzresult Lwt.t + val fresh_temporary : context -> context * id + val mem : context -> id -> Script_expr_hash.t -> (context * bool) tzresult Lwt.t + val get_opt : context -> id -> Script_expr_hash.t -> (context * Script.expr option) tzresult Lwt.t + val rpc_arg : id RPC_arg.t + val cleanup_temporary : context -> context Lwt.t + val exists : context -> id -> (context * (Script.expr * Script.expr) option) tzresult Lwt.t +end + module Contract : sig include BASIC_DATA @@ -615,11 +627,20 @@ module Contract : sig val fresh_contract_from_current_nonce : context -> (context * t) tzresult Lwt.t val originated_from_current_nonce: since: context -> until:context -> contract list tzresult Lwt.t - type big_map_diff_item = { - diff_key : Script_repr.expr;

It must return a stack containing a +single pair whose first element is the list of internal operations +that it wants to emit, and second element is the new contents of the +storage space. Alternatively, a Michelson program can fail, explicitly +using a specific opcode, or because something went wrong that could +not be caught by the type system (e.g. gas exhaustion). + +A bit of polymorphism can be used at contract level, with a +lightweight system of named entrypoints: instead of an input value, +the contract can be called with an entrypoint name and an argument, +and these two component are transformed automatically in a simple and +deterministic way to an input value. This feature is available both +for users and from Michelson code. See the dedicated section. + +Inter-transaction semantics +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +An operation included in the blockchain is a sequence of "external +operations" signed as a whole by a source address. These operations +are of three kinds: + + - Transactions to transfer tokens to implicit accounts or tokens and + parameters to a smart contract (or, optionally, to a specified + entrypoint of a smart contract). + - Originations to create new smart contracts from its Michelson + source code, an initial amount of tokens transferred from the + source, and an initial storage contents. + - Delegations to assign the tokens of the source to the stake of + another implicit account (without transferring any tokens). + +Smart contracts can also emit "internal operations".

In particular, +Michelson has two types to talk about other accounts: ``address`` and +``contract t``. The ``address`` type merely gives the guarantee that +the value has the form of a Tezos address. The ``contract t`` type, on +the other hand, guarantees that the value is indeed a valid, existing +account whose parameter type is ``t``. To make a transaction from +Michelson, a value of type ``contract t`` must be provided, and the +type system checks that the argument to the transaction is indeed of +type ``t``.

If the +transaction specifies an entrypoint, but there is no such constructor +annotation, the transaction fails. + +For instance, suppose the following input type. + +``parameter (or (or (nat %A) (bool %B)) (or %maybe_C (unit %Z) (string %C)))`` + +The input values will be wrapped as in the following examples. + +:: + + +------------+-----------+---------------------------------+ + | entrypoint | input | wrapped input | + +------------+-----------+---------------------------------+ + | %A | 3 | Left (Left 3) | + | %B | False | Left (Right False) | + | %C | "bob" | Right (Right "bob") | + | %Z | Unit | Right (Left Unit) | + | %maybe_C | Right "x" | Right (Right "x") | + | %maybe_C | Left Unit | Right (Left Unit) | + +------------+-----------+---------------------------------+ + | not given | value | value (untouched) | + | %BAD | _ | failure, contract not called | + +------------+-----------+---------------------------------+ + +The ``default`` entrypoint +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +A special semantics is assigned to the ``default`` entrypoint. If the +contract does not explicitly declare a ``default`` entrypoint, then it +is automatically assigned to the root of the parameter +type. Conversely, if the contract is called without specifying an +entrypoint, then it is assumed to be called with the ``default`` +entrypoint. This behaviour makes the entrypoint system completely +transparent to contracts that do not use it. + +This is the case for the previous example, for instance. If a value is +passed to such a contract specifying entrypoint ``default``, then the +value is fed to the contract untouched, exactly as if no entrypoint +was given. + +A non enforced convention is to make the entrypoint ``default`` of +type unit, and to implement the crediting operation (just receive the +transferred tokens). + +A consequence of this semantics is that if the contract uses the +entrypoint system and defines a ``default`` entrypoint somewhere else +than at the root of the parameter type, then it must provide an +entrypoint for all the paths in the toplevel disjunction. Otherwise, +some parts of the contracts would be dead code. + +Another consequence of setting the entrypoint somewhere else than at +the root is that it makes it impossible to send the raw values of the +full parameter type to a contract. A trivial solution for that is to +name the root of the type. The conventional name for that is ``root``. + +Let us recapitulate this by tweaking the names of the previous example. + +``parameter %root (or (or (nat %A) (bool %B)) (or (unit %default) string))`` + +The input values will be wrapped as in the following examples. + +:: + + +------------+---------------------+-----------------------+ + | entrypoint | input | wrapped input | + +------------+---------------------+-----------------------+ + | %A | 3 | Left (Left 3) | + | %B | False | Left (Right False) | + | %default | Unit | Right (Left Unit) | + | %root | Right (Right "bob") | Right (Right "bob") | + +------------+---------------------+-----------------------+ + | not given | Unit | Right Unit | + | %BAD | _ | failure, contract not | + +------------+---------------------+-----------------------+ + +Calling entrypoints from Michelson +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Michelson code can also produce transactions to a specific entrypoint. + +For this, both types ``address`` and ``contract`` have the ability to +denote not just an address, but a pair of an address and an +entrypoint.

This + EBNF is written out as LaTeX source. The output is a LaTeX "longtable" + environment, that can be included in any LaTeX document, typically + using an \input{} statement. + +What is the purpose of y2l? + + Questions about the purpose of things are so common, so here is the + answer to this very frequently asked question. When designing Abyss, I + found that I was continuously updating the grammar in two places. The + yacc description was of course the final authority. But I made it a + point to ensure that I would have decent and up-to-date documentation + for the language. Which led to the first incarnation of y2l. + + Then came the well known moment of truth when that first version was + used to try and generate an EBNF description for someone else's + grammar. That failed quite miserably because of implicit dependencies + on the format of the Abyss grammar description. A new y2l was written, + based around a strict yacc source file parser. It is designed to be + able to turn any yacc source file into an EBNF description, yet it + might choke on some Bison source files, because of large liberties the + authors of Bison have taken compared to the "original" yacc. This is + considered to be a "known bug" and might be solved in the future. + +What about portability? + + How portable is this little utility? Well, it's pretty portable in the + sense that is has been written in good ol' AWK! As long as you have a + machine with a sensible AWK (such as Gawk, or the one true AWK on + Brian Kernighan's homepage (http://plan9.bell-labs.com/cm/cs/who/bwk), + it will work. + + You may have to manually update the first line of the y2l script to + point to the proper AWK executable on your system. Not every system + has a sensible AWK as /usr/bin/awk! + +Where to download y2l? + + The latest release of y2l is available here for download + (http://y2l.sourceforge.net/download/y2l.tar.gz). + + The PGP signature for y2l is available at + http://y2l.sourceforge.net/download/y2l.tar.gz.asc.

DESCRIPTION

+This utility takes a +yacc(1) +grammar description file and generates an EBNF (Extended Backus-Naur Form) +grammar from it. By default, the output will be a +LaTeX(1) +longtable environment, that can be \input{} into any LaTeX document. Automatic +substitution of symbolic terminals can also be taken care of. Options control +whether any optimization should be done on the grammar, and whether plain ASCII +output should be generated instead. + +

OPTIONS

+
+
+-d +
+Write out debugging information to standard error. +
+-h +
+Display a short usage summary on standard output and exit. +
+-O +
+Optimize the yacc grammar. This basic optimization will look for empty rules to +make non-terminals optional. It also recursively generates choice groups and +optional groups and elements based on common prefix and suffix token lists. +
+-O0 +
+Turn off optimization. +
+-O1 +
+This gives the same optimization as the regular +-O +option. +
+-O2 +
+Do basic optimization. In addition, multiple rules for the same non-terminal +are combined as a choice group. Rules that were optimized by the first phase +as optional non-terminals are converted into repetitive rules if possible. +

+-tregexp +
+Use the provided regular expression to determine whether a terminal is a lexical +token rather than a literal. This is useful for grammars where literal tokens +represent string literals that differ only in that the string literals are all +lowercase versions of the token. Since this is a fairly common practise in yacc +grammars, this option ha sbeen provided. +

1  Introduction

Ott is a tool for writing definitions of programming languages and +calculi. +It takes as input a definition of a language syntax and semantics, in +a concise and readable ASCII notation that is close to what one would +write in informal mathematics. It generates output: +

  1. +a LaTeX source file that defines commands to build a typeset version of +the definition; +
  2. a Coq version of the definition; +
  3. a HOL version of the definition; +
  4. an Isabelle/HOL version of the definition; +
  5. a Lem version of the definition; +
  6. an OCaml version of the syntax of the definition. +

+Additionally, it can be run as a filter, taking a +LaTeX/Coq/Isabelle/HOL/Lem/OCaml source file +with embedded (symbolic) terms of the defined language, parsing them and replacing +them by typeset terms.

This document is a user guide for the tool. The papers +

+give an overview of the project, including discussion of motivation, +design decisions, and related work, and one should look at that together +with this manual. The project web page +

+http://www.cl.cam.ac.uk/users/pes20/ott/ +

+links to the github source repository, with a +BSD-style licence. It also has a range of examples, including +untyped and simply typed CBV lambda calculus, ML polymorphism, various +first-order systems from Pierce’s TAPL [Pie02], the +POPLmark F<: language [ABF+05], a module system by +Leroy [Ler96, §4] (extended with a term language and an +operational semantics), the LJ Java fragment and LJAM Java module +system [SSP07], and a substantial fragment of OCaml.

Our main goal is to support work on large programming language +definitions, where the scale makes it hard to keep a definition +internally consistent, and hard to keep a tight correspondence between a +definition and implementations. +We also wish to ease rapid prototyping work with smaller calculi, +and to make it easier to exchange definitions and definition fragments +between groups. +Most simply, the tool can be used to aid completely informal LaTeX mathematics. +Here it permits the definition, and terms within proofs and +exposition, to be written in a clear, editable, ASCII notation, without LaTeX +noise. It generates good-quality typeset output. +By parsing (and so sort-checking) this input, it quickly catches a +range of simple errors, e.g. inconsistent use of judgement forms or +metavariable naming conventions. +That same input, extended with some additional data, can be used to generate formal definitions for +Coq, HOL, Isabelle, and Lem. It should thereby enable a smooth transition +between use of informal and formal mathematics. Further, the +tool can automatically generate definitions of functions for free +variables, single and multiple substitutions, subgrammar checks +(e.g. for value subgrammars), and binding auxiliary functions. +Ott supports a ‘fully concrete’ representation, sufficient +for many examples but not dealing with general alpha equivalence. +An experimental Coq backend generates definitions in locally-nameless style for a subset of the Ott metalanguage. +The OCaml backend +generates type definitions that may be useful for developing a complete +implementation of the language, together with the functions listed +above. It does not generate anything for inductively defined relations +(the various proof-assistant code extraction facilities can +sometimes be used for that). +Our focus here is on the problem of writing and editing language +definitions, not (directly) on aiding mechanized proof of metatheory. If one +is involved in hard proofs about a relatively stable small calculus +then it will aid only a small part of the work (and one might choose +instead to work just within a single proof assistant), but for larger +languages the definition is a more substantial problem — so much so +that only a handful of full-scale languages have been given complete definitions. We +aim to make this more commonplace, less of a heroic task.

2.3  To build

+

2.3.1  With OPAM

If you have OPAM installed on your +system, opam install ott will install the latest Ott version. +The Emacs mode will be in +‘opam config var prefix‘/share/emacs/site-lisp, and +documentation in ‘opam config var prefix‘/doc/ott.

To install the Ott auxiliary files for Coq, first activate the +coq-released OPAM repository:

opam repo add coq-released https://coq.inria.fr/opam/released

and then run opam install coq-ott.

+

2.3.2  Without OPAM

Ott depends on OCaml version 4.00.0 or later. It builds with (at least) +OCaml 4.02.3.

The command make (make world) builds the ott +binary in the bin/ subdirectory.

This will compile Ott using ocamlopt. To force it to compile +with ocamlc (which may give significantly slower execution of +Ott), do make world.byt.

To build the Ott auxiliary files for Coq, go to the coq/ +subdirectory and run make. To install the resulting files in +Coq’s user-contrib, run make install.

+

2.4  To run

Ott runs as a command-line tool. Executing bin/ott shows the +usage and options. To run Ott on the test file +tests/test10.ott, generating LaTeX in test10.tex and +Coq in test10.v, type:

bin/ott -i tests/test10.ott -o test10.tex -o test10.v

Isabelle, HOL, and Lem can be generated with options +-o test10.thy, -o test10Script.sml, and +-o test10.lem, respectively.

The Makefile has various sample targets, make tests/test10.out, +make test7, etc. Typically they generate:

ll + +

+ + + + + + +
filenamedescription
out.texLaTeX source for a definition
out.psthe postscript built from that
out.vCoq source
outScript.smlHOL source
out.thyIsabelle source

from files test10.ott, test8.ott, etc., in +tests/.

+

2.5  Manual

+

2.6  Editor Plugins

+

2.6.1  Emacs mode

The file emacs/ott-mode.el defines a very simple Emacs mode for +syntax highlighting of Ott source files. It can be used by, for example, +adding the following to your .emacs file, replacing +PATH by a path to your Ott Emacs directory.

(setq load-path (cons (expand-file-name "PATH") load-path))
+(require 'ott-mode)
+

For installations using OPAM on *nix systems, it is sufficient to use +the following code, which will call opam config var prefix at +load-time.

(setq opam-share (substring (shell-command-to-string "opam config var share") 0 -1))
+(add-to-list 'load-path (concat opam-share "/emacs/site-lisp"))
+(require 'ott-mode)
+
+

2.6.2  Visual Studio Code

There is a +plugin +for VSCode, which features syntax highlighting and inline error +reporting.

+

2.7  Mailing lists

+

2.8  Web page with examples

+

2.9  Copyright information

The ocamlgraph library is distributed under the LGPL (from +http://www.lri.fr/∼filliatr/ftp/ocamlgraph/); we include +a snapshot for convenience. For its authorship and copyright information +see the files therein.

3  A minimal Ott source file: the untyped CBV lambda calculus

Fig. 1 shows an Ott source file for an untyped call-by-value +(CBV) lambda calculus. This section explains the basic features that +appear there, while in the following sections we show what must be +added to generate typeset output, proof assistant definitions, and +other things. +

Figure 1: Source: test10.0.ott
+

+The figure is colourised, with Ott keywords like this and Ott +symbols such as | and ::. Other user-specific input +appears like this.

At the top of the figure, the metavar declaration introduces +a sort of metavariables termvar (with synonym x), for term +variables. +The following grammar introduces two grammar rules, one for terms, with +nonterminal root +t, and one for values v. +This specifies the concrete syntax of object-language terms, +the abstract syntax representations for proof-assistant mathematics, +and the syntax of symbolic terms to be used in semantic rules.

Each rule has a rule name prefix (e.g. ’t_’) and then a list +of productions. Each production, e.g. +

+  | \ x . t      ::  :: Lam
+

+specifies a syntactic form as a list of elements, here ‘\’, +‘x’, ‘.’, and ‘t’, each of which is either a +metavariable (the ‘x’), a nonterminal (the ‘t’), or a +terminal +(\ . ( ) { } / -->). +Within productions all elements must be whitespace-separated, so that +the tool can deduce which are terminals. In the symbolic terms in +the semantic rules below, however, whitespace is required only where necessary. +A few terminals have to be quoted (with '') if they appear in a grammar, e.g. to +use | as an object-language token, as they are part of the Ott syntax, but they +do not have to be quoted at usage points. +(If one accidentally omits inter-token whitespace in the grammar, the +output of Ott can be surprising. This is best diagnosed by looking at +the colourised ASCII or LaTeX output from Ott.)

Metavariables and nonterminals can be formed from the specified +metavariable and nonterminal roots by appending a suffix, e.g. the +nonterminal t' in the App and Tsub productions.

Between the ::’s is an optional meta flag M or S. Non-meta +productions give rise to clauses of datatype definitions in the +Isabelle/Coq/HOL output, whereas meta productions do not. Later, we +will see how the user can specify how meta syntax should be translated +away when generating proof assistant output. The two flags M +and S are identical except that productions with the latter are +admitted when parsing example concrete terms; the S tag is thus +appropriate for lightweight syntactic sugar, such as productions for +parentheses. One can also use an X flag here to suppress a +production in the generated LaTeX.

Each production has a production name (e.g. t_Lam), composed of +the rule name prefix (here t_) and the production name kernel +that follows the ::’s (here Lam). The production name is +used as a constructor name in the generated Isabelle/Coq/HOL.

The tool supports arbitrary context-free grammars, extended with +special constructs for list forms (c.f. §12).

Following the grammar in this example is a subrule +declaration +

+  subrules
+    v <:: t
+

+declaring that the v grammar rule (of values) is a +subgrammar of the t rule (of terms). The tool checks that +there is in fact a subgrammar relationship, i.e. that for each +production of the lower rule there exists a production of the higher +rule with corresponding elements (up to the subrule relation). +The subrule declaration means that, in the semantic rules below, we +will be able to use v’s in places where the grammar specifies t’s. +In the generated Isabelle/Coq/HOL for this example only one free +datatype will be generated, for the t rule, while for the v +rule we generate an is_v predicate over the t type. Usages of +v nonterminals in the semantic rules will have instances of this +predicate automatically inserted.

Finally, we give a collection of definitions of inductive relations. +In this example there is just one family of definitions (of +operational judgements), introduced by the defns Jop; it contains just one +definition of a relation, called reduce. +In general there may be many defns blocks, each of which introduces a +mutually recursive collection of defns. +The relation definition +defn ... +also includes a grammar production specifying how elements of the +relation can be written and typeset, here +

  t1 --> t2
+

As in the main grammar, the tokens of this syntax definition in the +header must be space-separated, but usages of the syntax generally +need not be. +Syntax rules for each family of +judgements, and for their union, are implicitly generated. +The relation definition is given by a sequence of inference rules, +each with a horizontal line separating a number of premises from a +conclusion, for example as below. +

+    t1 –> t1’
+    -------------- :: ctx_app_arg
+    v t1 –> v t1’
+

+The conclusion must be a symbolic term of the form of the judgement being +defined. +In simple cases (as here) the premises can be symbolic terms of the +form of any of the defined judgements. More generally (see +§6) they can be symbolic terms of a user-defined +formula grammar, or in-line embedded prover code. +Each rule +has a name, composed of a definition family prefix +(here empty), a definition prefix (here also empty) and a kernel +(the ctx_app_arg). +

The symbolic terms in semantic rules are parsed with a scannerless parser, built +using parser combinators over character-list inputs. The parser +searches for all parses of the input. If none are found, the ASCII +and TeX output are annotated no parses, with a copy of the +input with *** inserted at the point where the last token was +read. This is often at the point of the error (though if, for +example, a putative dot form is read but the two element lists cannot +be anti-unified, it will be after the point of the error). +If multiple parses are found, the TeX output is annotated +multiple parses and the different parses are output to the +console in detail during the Ott run. +If the option picky_multiple_parses is set to +true, multiple parses are always reported. If it set to +false, a symbolic term is considered ambiguous only if two +different parses compile to different strings (for a target). +The parser combinators use memoization and continuation-passing to +achieve reasonable performance on the small symbolic terms that are +typical in semantic rules. Their performance on large (whole-program +size) examples is untested. +To resolve ambiguity one can add metaproductions for parentheses (as +in Fig. 1), or +production-name annotations in particular symbolic terms, +e.g. the :t_tsub: in the AppAbs rule of the POPLmark +example, +test7.ott. There is currently no support for precedence +or associativity.

+from the main directory. This simply reads in the file, checking that +it is well-formed. Adding options: +

+   bin/ott -show_sort true -show_defns true -i tests/test10.0.ott
+

+it echos a colourised version to the screen, +with metavariables in red, nonterminals +in yellow, terminals in green, and object variables in white. +The colourisation uses vt220 control codes; if they do not work on +your screen add -colour false to the middle of the command +line. To suppress the echo of the definition, add +-show_post_sort false and -show_defns false.

+

3.1  Index variables

+In addition to the metavar declarations above, the user can declare any number of distinguished index +metavariables, e.g. by: +

+  indexvar index, i, j, n, m ::= {{ isa num }} {{ coq nat }} {{ hol num }} 
+

+Given such a declaration, index, i, j, n +and m can be used in suffixes, e.g. in the production +

+   |  ( t1 , .... , tn )           :: :: Tuple
+

+There is a fixed ad-hoc language of suffixes, including numbers, primes, and index variables (see §23). +Index metavariables cannot themselves be suffixed.

+

4  Generating LaTeX

The example from the previous section can already be used to generate +LaTeX, for example by executing +

+   bin/ott -i tests/test10.0.ott -o out.tex 
+

+to produce a LaTeX file out.tex. One often needs to +fine-tune the default typesetting, as illustrated in +Figure 2 (the Ott source) and Figure 3 +(the resulting LaTeX). +(The latter was built using the additional option -tex_show_meta false, to +suppress display of the metaproductions.) +

+


+ +
+
Figure 3: Generated LaTeX: test10.2.tex
+

+The source file has three additions to the previous file. +Firstly, the metavar declaration is annotated with a +specification of how metavariables should be translated to LaTeX: +

+  metavar termvar, x ::=   
+    {{ tex \mathit{[[termvar]]} }}
+

+Inside the {{ tex }} +is some LaTeX code +\mathit{$[[termvar]]$} +giving the translation of a termvar or x. Here they +are typeset in math italic (which in fact is also the default). +Within the translation, the metavariable itself can be mentioned +inside double square brackets [[ ]].

Secondly, there is a grammar for a distinguished nonterminal root +terminals, with a +{{ tex }} +translation for each, overriding the default typesetting of some +terminals. Note that the other terminals +(. ( ) { } /) +are still given their default typesetting. +

+  terminals :: ’terminals_’ ::=
+    | \            ::  :: lambda  {{ tex \lambda }}
+    | –>          ::  :: red     {{ tex \longrightarrow }}
+

+Thirdly, the file has com comments, including +the +{{ com term }} +attached to a grammar rule, +the +{{ com variable}} +attached to a production, and the +{{ com [[t1]] reduces to [[t2]]}} +attached to a semantic relation. These appear in the LaTeX output +as shown in Figure 3.

+

4.1  Specifying LaTeX for productions

+One can also specify tex translations for productions, overriding the default +LaTeX typesetting, e.g. as in this example of +a type abstraction production. +

+    |  X <: T . t   :: :: TLam   {{ tex \Lambda [[X]] [[<:]] [[T]]. \, [[t]] }}
+

+These homomorphisms, or homs1, can refer to the metavariables and +nonterminals that occur in the production, e.g. the [[X]], +[[T]], and [[t]] in the tex hom above, +interleaved with arbitrary strings and with typeset elements of the +terminals grammar, e.g. the [[<:]].

Homomorphisms are applied recursively down the structure of symbolic +terms. For example, an F<: term +

  (\X<:T11.t12) [T2]
+

would be LaTeX-pretty-printed, using the tex clause above, as +

( \, \Lambda  \mathit{X} <: \mathit{T_{\mathrm{11}}} . \, \mathit{t_{\mathrm{12}}} \, )
+ \, \, [ \, \mathit{T_{\mathrm{2}}} \, ]
+

which is typeset as below. +

+
+

+Note the X, T11 and t12 of the symbolic term are +used to instantiate the formal parameters X, T and +t of the homomorphism definition clause. +If the t itself had compound term structure, e.g. as below +

  (\X<:T. \X'<:T'.x)
+

the homomorphism would be applied recursively, producing +

( \, \Lambda  \mathit{X} <: \mathit{T} . \,  \Lambda  \mathit{X'} <: \mathit{T'} 
+. \,  \mathit{x} \,  \, )
+

typeset as follows. +

+
+

+Where there is no user-supplied homomorphism clause the LaTeX +pretty-printing defaults to a sequence of the individual items +separated by thin spaces (\,), +with reasonable default fonts and making use of the terminals grammar where appropriate.

+

4.2  Specifying LaTeX for grammar rules

+Grammar rules can include a tex hom specifying how all the +nonterminal roots should be typeset, e.g. +

+  type, t, s :: Typ_ ::=  {{ tex \mathsf{[[type]]} }} 
+        | unit                  ::   :: unit   
+        | type * type’          ::   :: pair   
+        | type -> type’         ::   :: fun    
+

Alternatively, the individual nonterminal roots can have tex +homs specifying how they should be typeset: +

+  G {{ tex \Gamma }} , D {{ tex \Delta }} :: ’G_’ ::= 
+        | empty                 ::   :: empty       
+        | G , x : T             ::   :: term        
+

+permitting the user to write G', D12 etc. in symbolic +terms, to be typeset as + +etc.

+

4.3  Using the LaTeX code

The generated LaTeX code can be used in two main ways. +By default, Ott generates a stand-alone LaTeX file, +with a standard wrapper (including a \documentclass, various +macro definitions, and a main body), +that gives the complete system definition.

The default header can be overridden by writing + embed {{ tex-wrap-pre ... }} and the default footer by +writing embed {{ tex-wrap-post ... }} . Alternatively, the +program option -tex_wrap false with the -tex_wrap false +command-line argument, one can generate a file that can be included in +other LaTeX files, that just defines macros to typeset various +parts of the system (-tex_wrap false overrides any +tex-wrap-pre/tex-wrap-post embeds).

The generated LaTeX output is factored into individual LaTeX +commands: for the metavariable declarations, each rule of the syntax +definition, the collected syntax (\ottgrammar), each rule of the inductive relation +definitions, the collected rules for each relation, the collected +rules for each defns block, the union of those +(\ottdefns) and the whole (\ottall). +This makes it possible to quote individual parts of the definition, +possibly out-of-order, in a paper or technical report.

If one needs to include more than one system in a single LaTeX +document, the ott prefix can be replaced using the +-tex_name_prefix command-line argument.

The generated LaTeX is factored through some common style macros, +e.g. to typeset a comment, a production, and a grammar. If necessary +these can be redefined in an embed block (see Section 8.1). +For example, the file tests/squishtex.ott +

+embed 
+ {{ tex-preamble
+\renewcommand{\[[TEX_NAME_PREFIX]]grammartabular}[1]
+  {\begin{minipage}{\columnwidth}\begin{tabular}{ll}#1\end{tabular}\end{minipage} }
+\renewcommand{\[[TEX_NAME_PREFIX]]rulehead}[3]
+  {$#1$  $#2$ & $#3$}
+\renewcommand{\[[TEX_NAME_PREFIX]]prodline}[6]
+  { \quad $#1$ \ $#2$ & \quad $#3 #4$  $#5$  $#6$}
+\renewcommand{\[[TEX_NAME_PREFIX]]interrule}
+  {\\[2.0mm]}
+ }}
+

+ +defines a more compact style for grammars. Note that the +[[TEX_NAME_PREFIX]] is replaced by whatever prefix is in force, +so such style files can be reused in different contexts.

A more sophisticated LaTeX package ottlayout.sty, providing fine control of how +inference rules and grammars should be typeset, is contained in the +tex directory of the distribution. It is described in the +manual therein.

+

5  Generating proof assistant definitions

To generate proof assistant definitions, for Coq, Isabelle, and HOL, +the minimal Ott source file of Section 3/Figure 1 must +be extended with a modest amount of additional data, as shown in Figure 4. +Executing +

+   bin/ott  -i tests/test10.4.ott  -o out.v  -o out.thy  -o outScript.sml 
+

+generates Coq out.v, Isabelle out.thy, and HOL +outScript.sml, shown in Figures 5, 6, and 7. +The additional data can be combined with the annotations for +LaTeX of the previous section, but those are omitted here. +

Figure 4: Source: test10.4.ott
+

+We add four things. +First, we specify proof assistant types to represent object-language +variables — in this example, choosing the string type of +Isabelle and HOL, and the nat type for Coq: +

+  metavar termvar, x ::=  
+  {{ isa string}} {{ coq nat}} {{ hol string}} {{ coq-equality }}
+

+For Coq output, one can specify {{ coq-equality proof-script }} +to build a decidable equality over the Coq representation type using +the proof proof-script. If the script is omitted, as in this +example, it defaults +to +

Proof.
+  decide equality; auto with ott_coq_equality arith.
+Defined.
+

where the ott_coq_equality database contains the decidable +equalities of the representation types defined in the source. It is +possible to suppress type generation for specific metavariables or nonterminals, by adding the +declaration {{ phantom }}. This is useful in some cases, for +instance to avoid duplicate definitions of types already defined in an +imported library. Any type homs are taken into account when +the metavariable or nonterminal root is output as a type.

Second, we specify what the binding is in the object language, with +the (+ bind x in t +) +annotation on the Lam production: +

+  | \ x . t      ::  :: Lam     (+ bind x in t +)
+

+Section 9 describes the full language of binding specifications.

Third, we add a block +

+  substitutions
+    single t x :: tsubst 
+

+to cause Ott to generate Coq/Isabelle/HOL definitions of a substitution +function, with name root tsubst, replacing metavariables x by terms t. This is for single +substitutions; multiple substitution functions (taking lists of +substitutand/substitutee pairs) can also be generated with the keyword +multiple. +Substitution functions are generated for all rules of the grammar for +which they might be required — here, just over t, with a +function named tsubst_t.

Finally, we specify translations for the metaproductions: +

+  | ( t )        :: S:: Paren   {{ icho [[t]]  }} 
+  | { t / x } t’ :: M:: Tsub    {{ icho (tsubst_t [[t]] [[x]] [[t’]])}}
+

+These specify that (t) should be translated into just the +translation of t, whereas +{t/x}t’ should be translated into the +proof-assistant application of tsubst_t to the translations +of t, x, and t’. +The (admittedly terse) icho specifies that these translations should be +done uniformly for Isabelle, Coq, HOL, and OCaml output. One can also +specify just one of these, writing +{{ coq }}, +{{ hol }}, +{{ isa }}, or +{{ ocaml }}, +or include several, with different translations for each. +There are also abbreviated forms ich, ic, ch, and ih. +The body of a proof assistant hom should normally include outer +parentheses, as in the Tsub hom above, so that it is +parsed correctly by the proof assistant in all contexts.

5.1  Proof assistant code for grammar rules

+The normal behaviour is to generate a free proof assistant type for +each (non-subrule, non-phantom) grammar rule. +For example, the Coq compilation for t here generates a free type with three +constructors: +

  Inductive term : Set := 
+   | t_var (x:var)
+   | t_lam (x:var) (t:term)
+   | t_app (t:term) (t':term).
+

(note that the metaproductions do not give rise to constructors).

Remark: prior to version 0.20.2, the free type generated for Coq was +

  Inductive term : Set := 
+   | t_var : var -> term
+   | t_lam : var -> term -> term
+   | t_app : term -> term -> term.
+

but we found that trying to preserve the names specified by the user +is helpful later, when doing proofs. Whenever a clash is detected, or +for list forms, the wildcard _ is used. The old behaviour +can be obtained via the top-level option +-coq_names_in_rules false.

By default the order of the arguments to those constructors follows +the order in which they appear in the production. That can be +overridden with an order hom. For example, if for some +reason (perhaps compatibility with other Coq code) one wished the +arguments to t_Lam to be reversed: +

   | t_Lam : t -> termvar -> t
+

one could add an order hom as below. +

+  | \ x . t      ::  :: Lam  {{ order [[t]] [[x]] }}
+

Instead of using the generated free type, one can specify an arbitrary proof assistant representation type, +annotating the grammar rule with a coq, isa, hol, or ocaml hom — +for example, in the following grammar for substitutions. +

+  s {{ tex \sigma }} :: ’S_’ ::= {{ com multiple subst }} {{ isa (termvar*t) list }}
+       | [ x |-> t ]            ::   :: singleton   {{ isa [ ([[x]],[[t]]) ]  }}
+       | s1 , .. , sn           ::   :: list        {{ isa List.concat [[s1 .. sn]] }}
+

+Here the {{ isa (termvar*t) list }} hom specifies that in +Isabelle output this type be represented as an Isabelle +(termvar*t) list instead of the default free inductive type; +all the productions are metaproductions (tagged M); and isa homs for each production specify how they should be translated into that Isabelle type. +This feature must be used with care, as any Ott-generated functions, e.g. substitution functions, cannot recurse through such user-defined types.

Grammar rules (whether free or non-free) can also include a coq equality hom, instructing +the Coq code generator to derive a decidable equality for the Coq +representation type. For example, the ML polymorphism Ott source of +test8.ott includes the following. +

+  typvar :: TV_ ::= {{ coq-equality decide equality. apply eq_value_name_t. }}
+       | ’ ident                ::   :: ident
+

The Coq/HOL/Isabelle/OCaml type name for a grammar rule, or for a +metavariable declaration, is normally +taken to be just its primary nonterminal root. +Occasionally it is useful to work around a clash between a +metavar or nonterminal primary root and a proof assistant symbol, +e.g. T in HOL or value in Isabelle. +For this, one can add a coq, hol, isa, or +ocaml hom to the primary nonterminal root. In the example +below, the user can write T, T’ etc. in their Ott +source, but the generated HOL type is Typ. +

+T {{ hol Typ }}, S, U :: ’T_’ ::=                    {{ com type  }}

+

The grammar rules within each grammar block of a syntax definition may depend on each other arbitrarily. +When generating Isabelle/Coq/HOL/OCaml representation types, however, they are +topologically sorted, to simplify the resulting induction +principles.

+

5.2  Proof assistant code for inductive definitions

+The semantic relations are defined +with the proof-assistant inductive relations packages, +Inductive, Hol_reln, and inductive_set or inductive, respectively. +Each defns block gives rise to a potentially mutually +recursive definition of each defn inside it +(it seems clearer not to do a topological sort here). +Definition rules are expressed internally with symbolic terms. +We give a simplified grammar thereof in Fig. 17, omitting the +symbolic terms for list forms. +A symbolic term st for a nonterminal root is either an explicit nonterminal or a +node, the latter labelled with a production name and containing a list of +symterm_elements, which in turn are either symbolic terms, +metavariables, or variables. +Each definition rule +gives rise to an implicational clause, essentially +that the premises (Ott symbolic terms of the formula grammar) +imply the conclusion (an Ott symbolic term of whichever judgement is +being defined). +Symbolic terms are compiled in several different ways: +

  • +Nodes of non-meta productions are output as applications of the appropriate proof-assistant constructor (and, for a subrule, promoted to the corresponding constructor of a maximal rule). +
  • Nodes of meta productions are transformed with the user-specified homomorphism. +
  • Nodes of judgement forms are represented as applications of the defined relation in Coq and HOL, and as set-membership assertions in Isabelle. +
  • Lists of formulae (the formula_dots production, c.f.§12) are +special-cased to proof-assistant conjunctions. +

+Further, for each nonterminal of a non-free grammar rule, +e.g. a usage of v' where v<::t, an additional premise +invoking the generated subrule predicate for the non-free rule is added, e.g. is_v v'. +For Coq and HOL, explicit quantifiers are introduced for all variables +mentioned in the rule. +For HOL, rules are tagged with their rule name (using clause_name).

+

5.3  Representation of binding

+At present the generated Isabelle/Coq/HOL uses fully concrete +representations of variables in terms, without any notion of alpha +equivalence, as one can see in Fig. 6: +see the t datatype of terms and the tsubst_t +substitution function there. +An experimental Coq backend generates definitions in locally-nameless style for a subset of the Ott metalanguage. This is work-in-progress, and it is extensively documented in http://moscova.inria.fr/ zappa/projects/ln_ott/. +We intend in future to generate other representations, and in some +circumstances homs can be used to implement other representations directly. +For a reasonably wide variety of +languages, however, one can capture the intended semantics of whole programs in +this idiom, subject only to the condition that standard library +identifiers are not shadowed within the program, as the operational +semantics does not involve reduction under binders — so any +substitutions are of terms which (except for standard library +identifiers) are closed. This includes the ML polymorphism example of +test8.ott. For languages which require a type +environment with internal dependencies, however, for example F<:, this is +no longer the case. The POPLmark F<: example given in test7.ott +has a type system which disallows all shadowing, a property that is +not preserved by reduction. However, a correct translation of F<: is generated by the Coq locally-nameless backend, and can be found in http://moscova.inria.fr/ zappa/projects/ln_ott/.

Further discussion of binding representations is in the Ott ICFP 2007 +paper and in a working draft +

Binding and Substitition. Susmit Sarkar, Peter Sewell, and Francesco +Zappa Nardelli. August 2007. +

+available from the Ott web page.

+

5.4  Helper functions for free variable and substitution functions

The generated free variable and substitution functions in the Coq output +(e.g., in Figure 5) often rely on a few standard library functions: +list_mem, list_assoc, list_minus, list_minus2. +In order to avoid dependencies on external libraries for defining those +functions, by default Ott generates the definitions for any such functions it +uses. It is possible to turn off the generation of definitions for +these such functions by writing the following directive early on in the source file:

+embed {{ coq-lib list_mem list_minus }}
+

This instructs Ott to avoid generating definition for list_mem and +list_minus, but to continue generating definitions for other functions +such as list_assoc and list_minus2.

Note about list_minus2: +Instead of using the function list_minus2, earlier versions of Ott +generated equivalent code based on list_filter, which was more +difficult to reason about. For backwards compatibility, however, we provide the +command-line option -coq_use_filter_fn for generating a definition using +the older code pattern.

+

5.5  Correctness of the generated proof assistant code

+We have attempted to ensure that the proof assistant definitions +generated by Ott are well-formed and what the user would intend. This +is not guaranteed, however, for several reasons: (1) There may be name +clashes between Ott-generated identifiers and proof assistant built-in +identifiers (or, in pathological cases, even among different +Ott-generated identifiers). (2) In some cases we depend on automatic +proof procedures, e.g. for HOL definitions. These work in our test +cases, but it is hard to ensure that they will in all cases. More +importantly, (3) the generation process is complex, so it is quite +possible that there is either a bug in Ott or a mismatch between the +user expectation and what the tool actually does. Ultimately one has +to read the generated proof assistant definitions to check that they +are as intended — but typically one would do this in any case, many +times over, in the process of proving metatheoretic results, so we do +not consider it a major issue.

+

5.6  Using the generated proof assistant code

+Note added 2017-11-30: the following is out of date.

Ott builds code for

+ + +
Coq 8.3http://coq.inria.fr/
HOL 4 (the current svn version)http://hol.sourceforge.net/
Isabelle/HOL (Isabelle 2011)http://isabelle.in.tum.de/

Given proof assistant files in the top-level directory of the +distribution, as produced at the start of this section +(Coq out.v, Isabelle out.thy, and HOL +outScript.sml), the various proof assistants can be invoked as follows.

+

5.6.1  Coq

+First run +

  make
+

in the coq directory of the distribution, to build the auxiliary files. +These include a core file (ott_list_core) of definitions that +are used in Ott-generated output. +At present these are only required when Coq native lists are used. +There are also various lemmas (in +ott_list.v) which may be useful; they can be made available with +Require Import ott_list.

For batch mode run +

  coqc -I coq  out.v
+

where coq is the path to the coq directory of the distribution.

The experimental locally-nameless backend requires the Metatheory library by Arthur Chargueraud, available from the project web page.

+

5.6.2  HOL

+First run +

  Holmake
+

in the hol directory of the distribution, to build the auxiliary files.

For +batch mode run +

  Holmake -I hol  outTheory.uo
+

where hol is the path to the hol directory of the distribution. +For interactive mode, run +

  hol -I hol
+

inside an editor window (where the second hol is again the path +to the hol directory of the distribution), and in +another window view the outScript.sml file. First +paste in the app load command from a comment at the top of the +file, then paste in the remainder.

+

5.6.3  Isabelle

+For batch mode: +

  echo 'ML_command {* (use_thy "Tmp"; OS.Process.exit OS.Process.success) handle e => (OS.Process.exit OS.Process.failure); *}' | /usr/local/Isabelle/bin/isabelle tty 
+

Interactively, using Proof General: +

  isabelle emacs out.thy
+
+

6  Judgments and formulae

In a semantic rule, for example +

+    t1 –> t1’
+    -------------- :: ctx_app_arg
+    v t1 –> v t1’
+

+the conclusion must be a symbolic term of the form of the judgement being +defined, but in general the premises may be symbolic terms +of a formula grammar or in-line embedded prover code. +By default the formula grammar includes all the defined judgement forms: for the +running example Ott will synthesise grammars as below.

The user can also define an explicit formula grammar, to let other +forms (not just judgements) appear as rule premises. Below is a +fragment of the formula grammar from the LJ example on the Ott web page. +

+  formula :: formula_ ::=  
+   |  judgement                       ::   :: judgement
+   |  formula1 .. formulan            ::   :: dots
+   |  not formula                     :: M :: not
+          {{ tex \neg [[formula]] }} 
+          {{ isa \<not> ([[formula]]) }}
+   |  ( formula )                     :: M :: brackets
+          {{ tex ([[formula]]\!) }}  
+          {{ isa [[formula]] }}
+   |  formula \/ formula:: M :: or
+          {{ tex [[formula]] \vee [[formula]] }}
+          {{ isa [[formula]] \<or> [[formula]] }}
+   |  formula /\ formula:: M :: and
+          {{ tex [[formula]] \wedge [[formula]] }}
+          {{ isa [[formula]] \<and> [[formula]] }}
+   |  x = x’                          :: M :: xali
+          {{ isa [[x]] = [[x’]] }}
+   |  X = X’                          :: M :: Xali
+          {{ isa [[X]] = [[X’]] }}
+

+This example adds (to the judgement forms) syntax for parenthesised +formulae, negation, and, or, and equality testing on two sorts. For +each, tex and isa homs specify how they should be +typeset and be translated into Isabelle.

If the user defines a formula grammar then (as here) the production +name prefix must be formula_ and the name for the +judgement production must be judgement.

+

6.1  Naming of premises for the Coq backend

+It is possible to specify the names of premises of inductive +predicates; these names are then used by the Coq backend, and are +often useful in proofs. For instance, we can call RED the hypothesis in the rule below +

+    t1 –> t1’  [[:RED]]
+    -------------- :: ctx_app_arg
+    v t1 –> v t1’
+

+which will then generate the following Coq code: +

+| ctx_app_arg : forall (v t1 t1’:term)
+    (RED: reduce t1 t1’),
+    is_val_of_term v ->
+    reduce (t_app v t1) (t_app v t1’).
+

+Names of rules cannot contain spaces or other non alpha-numerical +characters, and must begin with a letter. The name annotation must at +the rightmost place on the hypothesis line, and must be enclosed +(without spaces) between the [[: and ]] parentheses.

+

6.2  In-line embedded prover code in premises

+Instead of adding a formula production, one can directly embed prover +code as a premise, delimited as below by {{ and +}}. Within that, text will be echoed +directly to a prover (or given a default LATEX typesetting) except that symbolic terms enclosed within +[[ and ]] will be processed as in an +embed section. +

+  {{ type_to_chunk ([[typeof e1]]) = Some [[c]] }}
+  ----------------------------------------------------------- :: Assign1
+  e1=e2 . k |env   –tau–>    lval(e1) . [__=c e2] . k |env
+
+

6.3  User syntax

+The tool also synthesises a user_syntax grammar of all the +user syntax, for example:

This is used for parsing top-level strings, for example when filtering +embedded code (§8).

+

7  Concrete terms and OCaml generation

In semantic definitions, one typically never uses concrete variables, +only metavariables that range over them. +In examples, however, one may need either a mix of concrete variables +and metavariables, or, for strictly concrete terms, to restrict to +just the former (and also to prohibit symbolic nonterminals).

Figure 2 combines the LaTeX and proof assistant +annotations of Sections 3 and 4, adding a +{{ lex alphanum}} +hom +to the metavar declaration to specify the lexical form of +concrete variables of this sort. +At present a lex homomorphism must have body either +Alphanum (standing for [A-Z]([A-Z]|[a-z]|[0-9]|'|_)*), +alphanum (for ([A-Z]|[a-z])([A-Z]|[a-z]|[0-9]|'|_)*), +alphanum0 (for [a-z]([A-Z]|[a-z]|[0-9]|'|_)*), or +numeral (for [0-9][0-9]*); more general regular expressions are not supported. +An identifier that can be ambiguously lexed as either a concrete or +symbolic metavariable, e.g. x in the scope of the above +declaration, will be taken to be symbolic. +To restrict the parser to strictly concrete terms only, one can add a +:concrete: prefix, as shown in Figure 10.

One can also specify how concrete variables should be LaTeX’d or +translated into a proof assistant, e.g. with +homomorphisms +{{ texvar \mathrm{[[termvar]]}} +and +{{ isavar ’’[[termvar]]’’}} +(and similarly coqvar, holvar, and ocamlvar).

Figure 2 also specifies an OCaml representation type for +variables, with the metavar hom +{{ ocaml int}}. +Executing +

+   bin/ott -i tests/test10.ott -o test10.ml  
+

+produces the OCaml code shown in Figure 9, including OCaml +types to represent the abstract syntax, and auxiliary functions for +subrules and substitutions. This does not implement the semantic +rules. In some cases the various proof assistant code extraction +facilities can be used — see Section 21.

8  Filtering: Using Ott syntax within LaTeX, Coq, Isabelle, +HOL, or OCaml

+

8.1  Filtering embedded code

It is possible to embed arbitrary code in +the Ott source using an embed block, which can contain +tex, +coq, +hol, +isa, or +ocaml homomorphisms, the +bodies of which will appear in the respective output. +The embed keyword should be on a line by itself). For +example, +test8.ott contains the following to +define Coq and HOL remove_duplicates functions. +

+embed
+{{ coq
+Fixpoint remove_duplicates (l:list typvar_t) : list typvar_t :=
+  match l with
+  | nil => nil
+  | cons h t => if (list_mem eq_typvar_t h t)  then remove_duplicates t
+                else cons h (remove_duplicates t)
+end. }}
+
+{{ hol
+val _ = Define ‘
+  (remove_duplicates [] = []) /\
+  (remove_duplicates (x::xs) = if (MEM x xs) then remove_duplicates xs 
+                               else x::(remove_duplicates xs))
+‘; }}
+

+Within the body of an embed homomorphism, any text between +[[ and ]] will be parsed as a symbolic term (of the +user_syntax grammar) and pretty printed, so one can use user +syntax within LaTeX or proof assistant code. An Isabelle example +is below, defining an Isabelle function to calculate the order of a +type with productions unit, t*t', and t->t'. +

+{{ isa
+consts
+order :: "type => nat"
+primrec
+"order [[unit]] = 0"
+"order [[t*t’]] = max (order [[t]]) (order [[t’]])"
+"order [[t->t’]] = max (1+order [[t]]) (order [[t’]])"
+
+}}
+

+It is often useful to define a proof assistant function, in an +embed section, together with a production of the formula +grammar with a proof assistant hom that uses that function, thereby +introducing syntax that lets the function be used in semantic rules.

Ott also permits embed blocks with tex-preamble, +homs, whose +contents appear in the generated LATEX preamble. +Any definitions of LATEX commands must appear in such a +tex-preamble section. +

+

8.2  Filtering files

+Similar processing can be carried out on separate files, using the +command-line options tex_filter, isa_filter, etc. +Each of these takes two arguments, a source filename and a destination +filename. In processing the source file, +any text between +[[ and ]] will be parsed as a symbolic term (of the +user_syntax grammar) and pretty printed in the appropriate +style. All other text is simply echoed. +

Typical usage for LaTeX would be something like this (from the Makefile +used to produce this document): +

test7.tex: ../src/ott ../tests/test7.ott ../tests/test7tt.mng
+         cd ../src; make tmp_test7_clean.ott
+         ../src/ott                                        \
+                -i ../src/tmp_test7_clean.ott              \
+                -o test7.tex                               \
+                -tex_show_meta false                       \
+                -tex_wrap false                            \
+                -tex_name_prefix testSeven                 \
+                -tex_filter ../tests/test7tt.mng test7tt.tex 
+

The -tex_wrap false turns off output of the default LaTeX +document preamble, so the generated file test7.tex just contains +LaTeX definitions. +The -tex_name_prefix testSeven sets a prefix for the generated +LaTeX commands +(so the LaTeX definitions from multiple Ott source files can be +included in a single LaTeX document). +The -tex_filter argument takes two +filenames, a source and a destination. It filters the source file, +(roughly) replacing any string found within [[ ]] by +the tex pretty-print of its parse. This parsing is done w.r.t. the generated nonterminal +user_syntax which is a union of all the user’s grammar.

At present munged strings are not automatically +put within $ $, and there is no analogue of the +<[ ]> of our previous munger.

The lexing +turns any sequence of [ (resp. of ]) of +length n+1 for n>2 into a literal sequence of length n.

Figures 10 and 11 show a source file (test7tt.mng) that uses terms of the F<: +definition of test7.ott, and the result of filtering it.

Similar filtering can be performed on Coq, Isabelle, HOL, and OCaml files.

To filter files with respect to a relatively stable +system definition, without having to re-process the Ott source files of +that system definition each time, there are command-line options +

  -writesys <filename>                Output system definition
+  -readsys <filename>                 Input system definition
+

to first write the system definition (generated from some source files) to a file, and +then to read one back in (instead of re-reading the Ott source files). +The saved system definitions are in an internal format, produced using +the OCaml marshaller, and contain OCaml closures. They therefore will +not be compatible between different Ott versions. They may also be +quite large.


+
+We can TeX-typeset symbolic terms of the language, e.g.
+\[ [[ (\X<:Top. \x:X.x) [Top->Top] ]]\]
+and concrete terms
+\[ [[ :concrete: \Z1<:Top. \x:Z1.x ]]\]
+and similarly judgements etc, e.g.
+\[ [[G |- t : T ]] \]
+   
+Here is an extract of the syntax:
+
+\testSevengrammartabular{\testSevent\testSevenafterlastrule}
+
+and a single semantic rule:
+
+\[\testSevendruletinXXTwo{}\]
+
+and a judgement definition:
+
+\testSevendefnSA
+
+One can also include a ‘defns’ collection of judgements, or the complete definition.

9  Binding specifications

Our first example involved a production with a single binder: + +

specified by the source shown in Figure 4: +

+  | \ x . t      ::  :: Lam     (+ bind x in t +)
+

+in which a single variable binds in a single subterm. +Realistic programming languages often have much more complex binding +structures, e.g. structured patterns, multiple mutually recursive let definitions, +comprehensions, or-patterns, and dependent record patterns.

Ott has a flexible metalanguage for specifying binding structures, +expressive enough to cover these. +It comprises two forms of annotation on productions. +The first, + +lets one specify that variables bind in nonterminals of the +production, as in the Lam production above. +Here + +is a metavariable set expression, +e.g. in that lambda production just the singleton +metavariable + +of the production. +A variable can bind in multiple nonterminals, as in the example of +a simple recursive let below.

More complex examples require one to collect together sets of +variables. For example, the grammar below (shown in Ott source and the +generated LaTeX) has structured patterns, +with a +production in which all the binders of the pattern + +bind in the continuation + +

+t :: E_ ::=
+  | x                        ::   :: ident
+  | ( t1 , t2 )              ::   :: pair
+  | let p = t in t’          ::   :: letrec      (+ bind binders(p) in t’ +)
+
+
+p :: P_ ::=
+  | _                        ::   :: wildcard    (+ binders = {} +)
+  | x                        ::   :: ident       (+ binders = x +)
+  | ( p1 , p2 )              ::   :: pair        (+ binders = binders(p1) union binders(p2) +)
+

This is expressed with the second form of annotation: user-defined +auxiliary functions such as the +binders above. This is an auxiliary function defined over the + +grammar that identifies a set of variables to be +used in the bind annotation on the +production. There can be any number of such auxiliary functions; +binders is not a distinguished keyword.

The syntax of a precise fragment of the binding metalanguage is given in +Fig. 12, + +


+
+
Figure 12: Mini-Ott in Ott: the binding specification metalanguage
+

where we have used Ott to define part of the Ott +metalanguage. A simple type system (not shown) enforces sanity properties, +e.g. that each auxiliary function is only applied to nonterminals that +it is defined over, and that metavariable set expressions are +well-sorted.

Further to that fragment, the tool supports binding for the list forms +of §12. +Metavariable set expressions can include lists of metavariables +and auxiliary functions applied to lists of nonterminals, e.g. as in +the record patterns below. +

This suffices to express the binding structure of almost all the +natural examples we have come across, including definitions of +mutually recursive functions with multiple clauses for each, Join +calculus definitions [FGL+96], dependent record patterns, and many others.

+

10  Generating substitution and free variable functions

The tool can generate Isabelle/Coq/HOL/OCaml code for both single and multiple +substitution functions. For example, the ML polymorphism Ott source +of test8.ott includes the following. +

+  substitutions
+    single   expr value_name :: subst  
+    multiple typexpr typvar  :: tsubst 
+

+This causes the generation of two families of substitution +functions, one replacing a single value_name by a expr, +the other replacing multiple typvars by typexprs.

Each family contains a function for each datatype for which it is +required, so in that example there are functions +subst_expr for the first and tsubst_typexpr, +tsubst_typscheme and tsubst_G for the second.

The functions for substitutions declared by +

+  substitutions
+    single   this that :: name1 
+    multiple this that :: name2 
+

+replaces terms of productions consisting just of a single that by a +this. +Here this must be a nonterminal root, while that can be +either a metavariable root or a nonterminal root (the latter +possibility allows substitution for compound identifiers, though it is +not clear that this is generally useful enough to be included). +Substitution functions are generated for each member of each (mutually recursive) +block of grammar rules which either contain such a production or (indirectly) +refer to one that does.

At present multiple substitutions are represented by Isabelle/Coq/HOL/OCaml +lists, so for the example above we have Isabelle +

  tsubst_typexpr :: "(typvar*typexpr) list => typexpr => typexpr"
+  tsubst_typscheme :: "(typvar*typexpr) list => typscheme => typscheme"
+  tsubst_G :: "(typvar*typexpr) list => G => G"
+

The generated functions do not substitute bound things, and recursive +calls under binders are filtered to remove the bound things.

Similarly, the tool can generate Isabelle/Coq/HOL/OCaml to calculate the free +variables of terms. For example, the ML polymorphism Ott source +of test8.ott includes the following. +

+  freevars
+    typexpr typvar :: ftv
+

+This causes Isabelle functions as below to be generated, calculating +the free typvars that occur in singleton productions in the +typexpr grammar, within terms of all types. +

  ftv_typexpr :: "typexpr => typvar list"
+  ftv_typscheme :: "typscheme => typvar list"
+  ftv_G :: "G => typvar list"
+
+

11  Locally-nameless representation

The Coq backend of Ott includes experimental support for a +locally-nameless representation (and co-finite quantification).

The user must specify which metavariables require a locally-nameless +representation via the repr-locally-nameless hom, +e.g.:

+metavar x ::= {{ repr-locally-nameless }} {{ com  term variable  }} 
+

As usual, metavariables can be bound in productions, using the +bindspec language, as in the lam production below: +

+grammar
+  t :: ’t_’ ::=                                         {{ com term }}
+    | x                   ::   :: Var                     {{ com variable }}         
+    | \ x . t             ::   :: Lam  (+ bind x in t +)  {{ com abstraction }}      
+    | t t’                ::   :: App                     {{ com application }}      
+    | ( t )               :: S :: paren   {{ coq [[t]] }} 
+    | { t / x } t’        :: M :: tsub    {{ coq (t_subst_t [[t]][[x  t’]]) }}
+

This definition gives rise to the datatype term below (here with option -coq_names_in_rules false): +

+Inductive term : Set := 
+| term_var_b : nat -> term 
+| term_var_f : var -> term 
+| term_lam : term -> term 
+| term_app : term -> term -> term.
+

Remarks: +

  1. +Productions containing metavariables susceptible to be bound +(e.g., term_var) give rise to two distinct constructors, one +(term_var_b) for de Bruijn indices to be used when the metavariable +is bound, one (term_var_f) for "free" variables. The type var, +together with decidable equality and several useful lemmas and +functions, is defined in the Metatheory library.

    In the current implementation, metavariables susceptible to be bound +in a symbolic term (eg. the x in the term_var +production) must be the only element of the production.

  2. Binder metavariables are erased from productions +(eg. term_lam), as in de Bruijn representation. +

Ott automatically generates the appropriate open functions +and lc predicates to test if terms are locally-closed. The +other support functions for substitutions and free-variables +(subst and fv) are generated once the user declares +the relevant substitutions and freevars sections.

Ott automatically compiles the symbolic terms that appear in rule +definitions into the appropriate terms in locally-nameless style. For +instance, the typing rule for the simply-typed lambda-calculus:

+    E,x:S |- t : T
+    ------------------ :: lambda
+    E |- \x.t : S->T
+

+is compiled into its locally-nameless representation: +

+Inductive typing : env -> term -> type -> Prop := (* defn typing *) 
+| ... 
+| typing_lambda : forall (L:vars) (E:env) (t:term) (S T:type), 
+   (forall x, x \notin L -> typing (E & x ~ S) (open_term_wrt_term t (term_var_f x)) T) -> 
+   typing E (term_lam t) (type_arrow S T).
+

For that, Ott follows the algorithm below. For each rule, +

  1. +for each nonterminal that appears in the rule, compute the +maximal set of binders under which it appears: for example, in the +rule lambda above, the maximal set of binders for the nonterminal t +is the singleton x, and it is empty for all the other nonterminals; +
  2. for each pair nonterminal / maximal binder set collected in +phase 1., go over all the occurrences of the nonterminal in the rule +and open them with respect to all the variables in the maximal +binding set except those under which this particular occurrence is +bound. In the example, this amounts to opening the occurrence of t +in the premise with respect to the metavariable x; +
  3. quantify using cofinite-quantification each metavariable that +has been used to open a nonterminal; +
  4. add hypothesis about local-closure to guarantee the invariant +that if a derivation holds, then the top-level terms involved are +locally-closed. +

+In some cases the user may want a finer control on which nonterminals +are opened and with respect to which metavariables. Consider for +instance the CBV beta-reduction rule: +

+    --------------------------  :: ax_app
+    (\x.t1) v2 –>  {v2/x}t1
+

+A naive application of the algorithm described above would open the +right hand side occurrence of t1 with respect to a +cofinitely-quantified x. Substitution should then be used to replace +the occurrences of x with v2, resulting in the awkward term +

+reduce (term_app (term_lam t1) v2) (subst_term v2 x (open_term_wrt_term t1 (term_var_f x)))
+

Instead, an idiomatic translation of CBV beta-reduction rule would +directly rely on the open function to substitute v2 for the +bound occurrences of x in t1, as in: +

+reduce (term_app (term_lam t1) v2) (open_term_wrt_term t1 v2)
+

A special syntax for production homomorphisms allow the user to specify this translation: +

+    | { t / x } t’        :: M :: tsub    {{ coq (t_subst_t [[t]][[x t’]]) }}
+

+In the homomorphism the nonterminal t’ is referred to with +[[x t’]] instead of the usual +[[t’]]: the prefixed x specifies +that occurrences of t’ should not be opened with respect to +the metavariable x. If this homomorphism is specified, then +the translation of the ax_app rule is exactly idiomatic Coq +shown above.

Current limitations: support for single binders only, no auxfn, Coq only.

Disclaimer: to compile rule definitions, Ott applies blindly the algorithm described above. Although in most of the cases, this generates a correct and idiomatic representation of the language, some language constructs might not be faithfully translated. Please, let us know if you find one of these cases. +

If Ott is invoked with the -coq_lngen option, then the +generated locally-nameless Coq code is compatible with Aydemir’s +lngen tool (http://www.cis.upenn.edu/ baydemir/papers/lngen/).

+

12  List forms

Ott has direct support for lists, both as dot forms such as + +and as list comprehensions such as + +. +Figure 13 shows an example semantic rule taken from our OCaml +fragment semantics, as both the generated LaTeX and its Ott +source, that involves several dot forms. +Other types commonly used in semantics, e.g. finite maps or sets, can +often be described with this list syntax in conjunction with type and +metaproduction homs to specify the proof assistant representation. +When using list forms, one usually also wants to add a list-of-formula +production to the formula grammar, e.g. (as in +test17.10.ott): +

+  formula :: formula_ ::=  
+   |  judgement                       ::   :: judgement
+   |  formula1 .. formulan            ::   :: dots
+

+The proof assistant code generation for such a production (which must +be named formula_dots) is special-cased to a list conjunction.


+
+ E |- e1 : t1 ... E |- en : tn
+ E |- field_name1 : t->t1 ... E |- field_namen : t->tn
+ t = (t1’, ..., tl’) typeconstr_name
+ E |- typeconstr_name gives typeconstr_name:kind {field_name1’; ...; field_namem’}
+ field_name1...field_namen PERMUTES field_name1’...field_namem’
+ length (e1)...(en)>=1

+

12.1  List dot forms

Example productions for +record types, record terms, and record +patterns are shown below, in both Ott source and LaTeX, taken +from our F<: example. +

+T, S, U :: ’T_’ ::=                                               {{ com type  }}
+  | { l1 : T1 , .. , ln : Tn }      :: :: Rec                       {{ com record }}           
+
+t :: ’t_’ ::=                                                     {{ com  term  }}
+  | { l1 = t1 ,  .. , ln = tn }     :: :: Rec                       {{ com record }}
+  | let p = t in t’                 :: :: Let (+ bind b(p) in t’ +) {{ com pattern binding}}
+
+p :: ’P_’ ::=                                                     {{ com  pattern }}
+  | x : T                           :: :: Var (+ b = x  +)          {{ com variable pattern }}
+  | { l1 = p1 , .. , ln = pn }      :: :: Rec (+ b = b(p1 .. pn) +) {{ com  record pattern  }}
+
+

+

Dot forms can be used in symbolic terms in semantic rules:

+

Individually indexed projections from dot forms can be mentioned, eg +the lj below:

+

Symbolic terms can also include concatenations of two dot forms with a +singleton in between:

+

Multiple dot forms within the same semantic rule can share bounds (e.g. 1..m):

+

In more detail, productions can have dot tokens interspersed between the elements. +Dot tokens consist of two, three or four consecutive dots (.., +..., or ....), indicating lists with minimum lengths 0, +1, and 2 respectively (these length minimums are respected +only when parsing concrete lists; they are not present in Isabelle/Coq/HOL +output). +The tool identifies the maximal sequence of elements on either side of +the dots that are identical modulo anti-unification of some +index. Optionally, there may also be a single terminal on either side +of the dot token, separating instances of the repeated unit. +For example, in the test7.ott production +

+  | { l1 = t1 ,  .. , ln = tn }  :: :: Rec                     
+

+there is such a terminal (the ‘,’). The tool identifies +that l1 = t1 and ln = tn can be anti-unified as +(roughly) l_ = t_, taking _ to be the bounds 1 and n. +A single production may contain multiple dot forms, but they must not overlap; +nested dot forms (including those with multiple changing indices) are not currently +supported.

Homomorphisms and binding specifications are generalised to match: an mse can +involve a dot form of metavariables; +a dot form of nonterminals; or an auxiliary function applied to a dot +form +of nonterminals (e.g. the +b(p1..pn) above). +Dot forms on the right of a bind are not currently supported.

LaTeX homomorphisms should not refer to dot forms, as either an error +or bad output will be generated. (For LaTeX, there should really be +some means to specify +a homomorphism for the repeated expression, and also data on how any +list separators should be typeset. This would require more +special-case treatment, which is not currently supported.)

+

12.2  List comprehension forms

Lists can also be expressed as explicit list comprehensions, +for more concise typesetting. +Three different styles are supported, with no bounds, an upper bound, +or a lower and upper bound. For example, in a symbolic +term, instead of the dot form +

+  G |- t1:T1  ..  G |- tn:Tn
+ 

+ +one can write any of the following +

+   </ G |- ti:Ti // i           />
+   </ G |- ti:Ti // i IN n      />
+   </ G |- ti:Ti // i IN 1 .. n />
+ 

+ +Similar comprehensions can be used in productions, for example lines +2–4 below. In addition, comprehensions in productions can specify a +terminal to be used as a separator in concrete lists, as in lines 5–7 below. +(These examples are taken from test17.10.ott.) +

+  |  l1 = t1 ,  .. , ln = tn            :: :: Rec              {{ com dots }}
+  |  </ li = ti // i           />       :: :: Rec_comp_none    {{ com comp }}
+  |  </ li = ti // i IN n      />       :: :: Rec_comp_u_none  {{ com compu }} 
+  |  </ li = ti // i IN 1 .. n />       :: :: Rec_comp_lu_none {{ com complu }}  
+  |  </ li = ti // , // i           />  :: :: Rec_comp_some    {{ com comp with terminal }}
+  |  </ li = ti // , // i IN n      />  :: :: Rec_comp_u_some  {{ com compu with terminal }} 
+  |  </ li = ti // , // i IN 1 .. n />  :: :: Rec_comp_lu_some {{ com complu with terminal }}  
+ 

+ +In Coq, HOL or Isabelle output, list dot forms and the +various list comprehension forms are treated almost identically. +In LaTeX output, comprension forms are default-typeset with overbars. +For example, the rules below +

+ G|- t:l1:T1,..,ln:Tn
+ ----------------------- :: Proj_dotform
+ G|- t.lj : Tj
+
+ G|- t:  </ li:Ti // i/> 
+ ---------------------------------- :: Proj_comp
+ G|- t.lj : Tj
+
+ G|- t:  </ li:Ti // i IN n/> 
+ ---------------------------------- :: Proj_comp_u
+ G|- t.lj : Tj
+
+ G|- t:  </ li:Ti // i IN 1..n/> 
+ ---------------------------------- :: Proj_comp_lu
+ G|- t.lj : Tj
+ 

+ +are typeset as follows.

+

Upper bounds of the form n−1 are also permitted, e.g. with +

+ G|- t:l0:T0,..,ln-1:Tn-1
+ ----------------------- :: Proj_dotform_minus
+ G|- t.lj : Tj
+
+ G|- t:  </ li:Ti // i IN 0..n-1/> 
+ ---------------------------------- :: Proj_comp_lu_minus
+ G|- t.lj : Tj
+ 

+ +typeset as below. More complex arithmetic expressions are not +currently supported.

+

A list form used in a symbolic term does not have to be in the same +style as that in the corresponding production. +However, if a metavariable or nonterminal occurs in multiple different +list forms in the same inference rule, they must all be in the same style and +with the same bounds. Moreover, in a production, a list form in a bindspec or +homomorphism must be in the same style and with the same bounds as the +corresponding list form in the elements of the production.

The comprehension form without an upper bound, +e.g. </ G |- ti:Ti // i />, +typeset as +is not standard +notation, but is often very useful. Many semantic rules involve lists +of matched length, e.g. of the +and +here, but do not need to introduce an +identifier for that length; omitting it keeps them concise.

The default visual style for typesetting list comprehensions can be +overridden by redefining the LaTeX commands \ottcomp, +\ottcompu, and \ottcomplu in an embed section, as +in Section 4.3.

In some cases one could make the typeset notation even less noisy, by +either omitting the superscript i or omitting both the superscript i and +the subscript i’s on t and T. The first is unambiguous if there +is at most one index on each element in the comprehension; the second +if all the elements are indexed by the same thing (not the case for +this example, but common for comprehensions of single elements, +e.g. << Ti // i>> for T). It is arguable that that +should be automated in future Ott releases, though it would bring the typeset and ASCII +versions out of step.

List comprehension forms can also be used in bindspecs and in +homomorphisms.

+

12.3  Proof assistant code for list forms

+

12.3.1  Types

+We have to choose proof assistant representations for productions involving list +forms. For example, for a language with records one might write +

+  metavar label, l ::= {{ hol string }} {{ coq nat }}
+  indexvar index, n ::=  {{ hol num }} {{ coq nat }} 
+  grammar
+  term, t :: ’t_’ ::=
+    | { l1 = t1 ,  .. , ln = tn }      :: :: record
+

+ +In HOL and Isabelle we represent these simply with contructors whose +argument types involve proof-assistant native list types, e.g. +the HOL list of pairs of a label and a t: +

  val _ = Hol_datatype ` 
+  t = E_record of (label#t) list  `;
+

For Coq we provide two alternatives: one can either use +native lists, or lists can be translated away, depending on taste. +The choice is determined by the -coq_expand_list_types +command-line option. +In the former case we generate an appropriate induction principle +using nested fixpoints, as +the default principle produced by Coq is too weak to be useful. +In the latter case we +synthesise an additional type for each type of lists-of-tuples that +arises in the grammar. +In the example, we need a type of lists of +pairs of a label and a t: +

Inductive 
+list_label_t : Set := 
+   Nil_list_label_t : list_label_t
+ | Cons_list_label_t : label -> t -> list_label_t 
+     -> list_label_t
+
+with t : Set := 
+   E_record : list_label_t -> t .
+

These are included in the grammar topological sort, and utility functions, e.g. to +make and unmake lists, are synthesised. +

+

12.3.2  Terms (in inductive definition rules)

+Supporting list forms in the rules of an inductive definition requires some additional analysis. For example, +consider the record typing rule below.

We analyse the symbolic terms in the premises and conclusion to +identify lists of nonterminals and metavariables with the same bounds — here t0 .. tn−1, T0 .. Tn−1, and l0 .. ln−1 +all have bounds 0..n−1. +To make the fact that they have the same length immediate in the +generated code, we introduce a single proof assistant +variable for each such collection, with appropriate projections and +list maps/foralls at the usage points. +For example, the HOL for the above is essentially as follows, with +an l_t_Typ_list : (label#t#Typ) list. +

(* Ty_Rcd *)  !(l_t_Typ_list:(label#t#Typ) list) (G:G) . 
+(EVERY (\b.b) 
+  (MAP (\(l_,t_,Typ_). (Ty G t_ Typ_)) l_t_Typ_list))
+ ==> 
+(Ty 
+  G 
+  (E_record (MAP (\(l_,t_,Typ_). (l_,t_)) l_t_Typ_list))
+  (T_Rec    (MAP (\(l_,t_,Typ_). (l_,Typ_)) l_t_Typ_list)))
+

This seems to be a better idiom for later proof development than the +alternative of three different list variables coupled with assertions +that they have the same length.

With direct support for lists, we need also direct support for +symbolic terms involving list projection and concatenation. +For example, the rule +

gives rise to HOL code as below — note the list-lifted usage of the +is_v_of_t predicate, and the list appends (++) in the conclusion. +

(* reduce_Rec *)  !(l'_t'_list:(label#t) list) 
+       (l_v_list:(label#t) list) (l:label) (t:t) (t':t) . 
+((EVERY (\(l_,v_). is_v_of_t v_) l_v_list) /\
+(( reduce t t' )))
+ ==> 
+(( reduce (t_Rec (l_v_list ++ [(l,t)] ++ l'_t'_list)) 
+          (t_Rec (l_v_list ++ [(l,t')] ++ l'_t'_list))))
+

For the Proj typing rule

we need a specific projection (the +HOL EL) to +pick out the j’th element: +

(* Ty_Proj *)  !(l_Typ_list:(label#Typ) list) 
+       (j:index) (G:G) (t:t) . 
+((( Ty G t (T_Rec (l_Typ_list)) )))
+ ==> 
+(( Ty 
+     G 
+     (t_Proj t  ((\ (l_,Typ_) . l_) (EL j l_Typ_list)))  
+     ((\ (l_,Typ_) . Typ_) (EL  j l_Typ_list))))
+

For Coq, when translating away lists, we have to introduce +yet more list types for +these proof assistant variables, in addition to the obvious +translation of symbolic terms, and, more substantially, to introduce additional inductive relation +definitions to induct over them.

For similar examples in Isabelle, the generated Isabelle for the first +three rules of §12.1 is +shown below (lightly hand-edited for format). The first involves an +Isabelle variable l_t_T_list, and list maps and projections +thereof. +

Ty_RcdI: "
+  [|(formula_formuladots ((List.map (%(l_,t_,T_).( ( G , t_ , T_ ) : Ty)) l_t_T_list)))|] 
+  ==> 
+  ( G , 
+    (t_Rec ((List.map (%(l_,t_,T_).(l_,t_)) l_t_T_list))) , 
+    (T_Rec ((List.map (%(l_,t_,T_).(l_,T_)) l_t_T_list))) 
+  ) : Ty"
+
+Ty_ProjI: "
+  [| ( G , t , (T_Rec (l_T_list)) ) : Ty|] ==> 
+  ( G , 
+    (t_Proj t (%(l_,T_).l_) (List.nth l_T_list (j - 1))) , 
+    (%(l_,T_).T_) (List.nth l_T_list (j - 1)) 
+  ) : Ty"
+
+E_Ctx_recordI: "
+[| List.list_all (%(l_,v_).is_v v_) l_v_list ;
+   ( t , t' ) : E|] 
+==> 
+ ( (t_Rec (l_v_list @ [(l,t)] @ l_'t_'list)) , 
+   (t_Rec (l_v_list @ [(l,t')] @ l_'t_'list)) 
+ ) : E"
+

+The generated code for substitutions and free variables takes account of such list structure.

Note that at present the generated Isabelle code for these functions +does not always build without change, in particular if tuples of size +3 or more are required in patterns.

+

12.3.3  List forms in homomorphisms

Proof assistant homomorphisms in productions can refer to dot-form +metavariables and nonterminals. For example, the second production +below (taken from test17.9) mentions [[x1 t1 ... xn tn]] in the isa +homomorphism. This must exactly match the dot form in the production +except that all terminals must be omitted — the metavariables and +nonterminals must occur in the same order as in the production, and +the bounds must be the same.

+    E :: ’E_’ ::= {{ isa ( ident * t ) list  }}
+      | < x1 : t1 , .. , xn : tn > :: :: 2  {{ isa  List.rev [[x1 t1 .. xn tn]] }}
+    formula :: formula_ ::=          
+      | judgement              :: :: judgement
+      | formula1 .. formulan   :: :: dots
+

+The generated Isabelle code for symbolic +terms mentioning this production will involve a list of pairs. For +example, the rules +

+defn
+|- E  :: :: Eok :: Eok_ by
+
+---------------------------- :: 2
+|- <x1:t1,..,xn:tn> 
+
+|- t1:K1  .. |- tn:Kn
+---------------------------- :: 3
+|- <x1:t1,..,xn:tn> 
+

+generate +

consts
+  Eok :: "E set"
+inductive Eok tK
+intros
+
+(* defn Eok *)
+
+Eok_2I: " ( List.rev  (x_t_list) ) : Eok"
+
+Eok_3I: "[|
+(List.list_all (\<lambda> b . b) (  ((List.map (%(x_,t_,K_). ( t_ , K_ ) : tK) x_t_K_list))  ) )|]
+ ==> 
+ ( List.rev  ((List.map (%(x_,t_,K_).(x_,t_)) x_t_K_list)) ) : Eok"
+ 

+Note that in the second the list of pairs is projected out from the +x_t_K_list list of triples that is quantified over in the rule.

+

13  Subrules

Subrule declarations have the form +

+  subrules
+    nt1 <:: nt2
+

+where nt1 and nt2 are nonterminal roots.

Subrules can be chained, i.e. there can be a pair of +subrule declarations nt1 <:: nt2 and nt2 <:: nt3, +and they can form a directed acyclic graph, e.g. with +nt0 <:: nt1, nt0 <:: nt2, +nt1 <:: nt3, and nt2 <:: nt3. However, there cannot be +cycles, or nonterminal roots for which there are multiple upper bounds. +Subrule declarations should not involve nonterminal roots for which +proof-assistant type homs are specified.

We support the case in which the upper rule is also +non-free, i.e. it contains productions that mention nonterminals that +occur on the left of a subrule declaration. In the example below +(test11.ott) the +t rule contains a production Foo v. +

+  metavar termvar , x ::=
+    {{ isa string }} {{ coq nat }} {{ coq-equality }} {{ hol string }} {{ ocaml int }}
+
+  grammar
+    t :: ’t_’ ::=                                         
+      | x                   ::   :: Var                   
+      | \ x . t             ::   :: Lam  (+ bind x in t +)
+      | t t’                ::   :: App                   
+      | Foo v               ::   :: Foo
+
+    v :: ’v_’ ::=                        
+      | \ x . t             ::   :: Lam   
+
+  subrules
+    v <:: t
+
+  defns

+

+      --------- :: ax
+      Baz t , v
+

+ +In this case generated Isabelle/Coq/HOL/OCaml will define a single type and both is_v +and is_t predicates, and the generated inductive definition +clause for ax uses both predicates. The Isabelle clause is below. +

  axI: "[|is_t t ; is_v v|] ==>  ( t , v ) : Baz"
+
+

14  Context rules

The system supports the definition of single-hole contexts, e.g. for +evaluation contexts. For example, suppose one has a term grammar as below: +

+t :: ’t_’ ::=                               {{ com term    }}
+  | x                  ::  :: Var                   {{ com variable}}
+  | \ x . t            ::  :: Lam (+ bind x in t +) {{ com lambda  }}
+  | t t’               ::  :: App                   {{ com app     }}
+  | ( t1 , .... , tn ) ::  :: Tuple                 {{ com tuple }}
+  | ( t )              :: S:: Paren                 {{ icho [[t]]  }} 
+  | { t / x } t’       :: M:: Tsub  
+                        {{ icho (tsubst_t [[t]] [[x]] [[t’]])}}
+
+  | E . t              :: M:: Ctx  
+                        {{ icho (appctx_E_t [[E]] [[t]])}}
+                        {{ tex [[E]] \cdot [[t]] }}
+

+A context grammar is declared as a normal grammar but with a single +occurrence of the terminal __ in each production, e.g. as in +the grammar for E below (a rather strange evaluation +strategy, admittedly). +

+E :: ’E_’ ::=                               {{ com evaluation context }}
+  | __ t         ::  :: AppL                   {{ com app L    }}
+  | v __         ::  :: AppR                   {{ com app R    }}
+  | \ x . __     ::  :: Lam                    {{ com reduce under lambda }}
+  | ( t1 ( __  t2 ) ) :: :: Nested              {{ com hole nested }}
+  | ( v1 , .. , vm , __ , t1 , .. , tn ) :: :: Tuple {{ com tuple }}
+

+A contextrules declaration: +

+contextrules
+  E _:: t :: t
+

+causes Ott to (a) check that each production of the E grammar +is indeed a context for the t grammar, and (b) generates +proof assistant functions, e.g. appctx_E_t, to apply a context +to a term: +

(** context application *)
+Definition appctx_E_t (E5:E) (t_6:t) : t :=
+  match E5 with
+  | (E_AppL t5) => (t_App t_6 t5)
+  | (E_AppR v5) => (t_App v5 t_6)
+  | (E_Lam x) => (t_Lam x t_6)
+  | (E_Nested t1 t2) =>  (t_App t1  (t_App t_6 t2) )
+  | (E_Tuple v_list t_list) => (t_Tuple ((app_list_t v_list
+     (app_list_t (Cons_list_t t_6 Nil_list_t) (app_list_t t_list Nil_list_t)))))
+

As the Nested production shows, context productions can +involve nested term structure.

Note also that here the E grammar is not free (it mentions the +subrule nonterminal v) so an isvalue predicate +is_E_of_E is also generated.

In general, context rule declarations have the form +

+  contextrules
+    ntE _:: nt1 :: nt2
+

+where ntE, nt1, and nt2 are nonterminal +roots. This declares contexts ntE for the nt1 +grammar, with holes in nt2 positions.

Just as for substitutions, the context application function is +typically used by adding a metaproduction to the term grammar. +Here we add a production E.t to the t grammar with +an icho hom that uses appctx_E_t. +

+t :: ’t_’ ::=                               {{ com term    }}
+  ...
+  | E . t              :: M:: Ctx  
+                        {{ icho (appctx_E_t [[E]] [[t]])}}
+                        {{ tex [[E]] \cdot [[t]] }}
+

+That can then be used in relations: +

+    t –> t’
+    -------------- :: ctx
+    E.t –> E.t’
+

One would typically also define a terminals production for +the hole terminal __, e.g. here we typeset the hole as [·]. +

+terminals :: ’terminals_’ ::=
+  | __           ::  :: hole    {{ tex [\cdot] }}
+
+

15  Auxiliary Rules

+We permit an aux hom on grammar rules. For any rule with such a hom, +we transform that rule by appending an _aux to its primary nonterminal +root name. We then add a synthesised rule with the original nonterminal +root name and a single production, with a shape described by the body of +the aux hom, which must be of the form +

  {{ aux  foo1 foo2 _ bar1 bar2 bar3 }}
+

with a single _ and any number of strings fooi and barj before and +after. The _ is replaced by the original +nonterminal root name.

For example, given a grammar or metavariable l of source locations, one +might say +

ntr :: 'NTR_'  ::=  {{ aux _ l }}
+ | ...
+

to synthesise grammars ntr_aux and ntr of unannotated and location-annotated +terms, the first with all the original productions and the second with a +single production +

 | ntr l :: :: NTR_aux. 
+

If the rule has an empty production name wrapper (eg with ’’ in place +of ’NTR_’) then the production name is based on the original +nonterminal root, capitalised and with _aux appended (eg Ntr_aux), to +avoid spurious conflicts.

An additional auxparams hom on rules lets the user add type +parameters to the generated OCaml output.

Generation of aux rules is controlled by a command-line option +-generate_aux_rules, which one might (eg) set to false +for latex output and true for OCaml output.

+

16  Functions

Ott includes experimental support for writing function definitions. +As a simple example, consider the Ott file below:

+    grammar
+     n :: ’n_’ ::=
+       | 0       :: :: Zero
+       | S n     :: :: Succ
+
+    funs
+      Add ::=   {{ hol-proof ...  }}
+    fun
+      n1 + n2 :: n :: add    {{ com a function of type num -> num -> num }}
+    by
+      0 + n2 === n2
+      S n1 + n2 === n1 + S n2
+

Here the add function is compiled into the following Coq code:

+    Fixpoint add (x1:num) (x2:num) : num:=
+      match x1,x2 with
+      | n_zero , n2 => n2
+      | (n_succ n1) , n2 =>  (add n1 (n_succ n2) ) 
+    end.
+

More in detail, the +fun +n1 + n2 :: n :: add +by +declaration specifies: +

  • +the name of the function: add +
  • the symbolic term that defines the lhs: n1 + n2 +
  • the non-terminal that defines the rhs: n +

The type of the arguments of the function is defined by the +non-terminals appearing in the lhs, the return type by the rhs +non-terminal (so numnumnum in the +above example). As side-effect, whenever a function of type +symb_termnt is defined, a production +nt ::= symb_term is added to the definition of the +non-terminal nt (in the above example, the production +n1 + n2 is added to the grammar of num).

Functions are then defined by case analysis, where the lhs and the rhs +are separated by the reserved symbol ===.

The {{ hol-proof }} hom +allows the specification of a termination proof, which is required by +Hol. Mutually recursive functions can be defined in the same +funs block, analogously to mutually recursive rule +definitions.

Disclaimer: the different treatment of partial functions by the +different provers can result in a function definition being compiled +correctly to one prover but not to others.

+

17  Parsing Priorities

Symbolic terms that can have more than one parse tree are typically considered +erroneous; however, certain classes of parse trees are ignored in order to +support common idioms that are ambiguous. For example, the production +

+
Γ ::= Γ1, .., Γn

+might be used to allow a list of typing contexts to be appended together, but +it is highly ambiguous. The following restrictions forbid many unwanted parses +that could otherwise occur. +

  • +All parses in which a nonterminal derives itself without consuming any input +are ignored. For example, in the production above, the list could otherwise be +of length one so that Γ directly derives Γ giving rise to a +vacuous cycle, and an infinite forest of parse trees. This restriction +ensures that only the tree without the vacuous cycle is considered. +
  • The parser for a list form ignores parses that unnecessarily break up the list +due to (direct or indirect) self reference. For example, +Γ1234 will not parse as a two element sequence +of two element sequences (Γ12),(Γ34) given the +production above. +
  • User supplied priority annotations in a parsing section rule out certain +trees as follows: +
    • +prodname1 <= prodname2: Parse trees where a +prodname1 node is a child of a prodname2 node are +ignored. +
    • prodname1 right prodname2: Parse trees where a +prodname1 node is the leftmost child of a prodname1 +node are ignored. +
    • prodname1 left prodname2: Parse trees where a +prodname2 node is the rightmost child of a prodname1 +node are ignored. +
    +In addition to immediate children, these priority annotations also prohibit +parse trees where the forbidden child node occurs underneath a chain of +derivations from the specified parent when the chain does not consume any +input. +Figure 17 demonstrates a typical use of a parsing +section; the declarations have effect as follows: +
    • +Line #1: n + n + n parses as (n + n) + n, but not n + (n + n); +
    • Line #3: n + n - n parses as (n + n) - n, but not n + (n - n); +
    • Line #9: -n + n parses as (-n) + n, but not -(n + n); +
    • Line #15: n + n n parses as n + (n n), but not (n + n) n; +n n + n parses as (n n) + n, but not n (n + n); +
    • Line #20: n, n n, n parses as n, (n n), n, but not (n, n) (n, n). +
    +Currently, the parsing section supports only these relatively low level +and verbose declarations. +

18  Combining multiple source files

+Ott can be invoked with multiple source files. +Input filenames with extensions .tex, .v, +.thy, .sml, or ml are simply copied into +the relevant output (LATEX, Coq, Isabelle, HOL, or OCaml). +By default the source-file and command-line order of blocks is preserved, for grammar, +embeds, and inductive definitions.

The prover output can be split into multiple output files: each prover +output file specified with -o <filename> will contain the material +from the previous input files specified with -i (since the last -o +for the same prover).

Alternatively, one can add a -merge true command-line option, +in which case +the productions of multiple grammars that share the same header +are merged into a single grammar, and the rules of multiple +inductive definitions that share the same header are merged into a +single inductive definition. +This rudimentary form of modularity can be very useful, either to +split a language definition into separate features, or to define +reusable Ott components to define standard formulae, LaTeX pretty +printing of terminals, or LaTeX styles. +For example, Figure 15 shows the Ott source file for a +let feature in isolation, taken from our Ott development of +some languages from Pierce’s TAPL [Pie02]. +


+
+

+t :: Tm ::=                                        {{ com terms: }}

+
+
+
+
Figure 15: An ott source file for the let fragment of TAPL
+

+The original TAPL languages were produced using +TinkerType [LP03] to compose features and check for +conflicts. +In examples/tapl we build a system, similar to the TinkerType +sys-fullsimple, from ott source files that +correspond roughly to the various TinkerType components, each with +syntax and semantic rules for a single feature.

+

19  Hom blocks

+Bindspecs and homomorphisms for productions, and any homomorphisms +for definitions, can appear in an Ott source file either +attached to the production or definition, as we have shown earlier, or +in separate hom blocks. +For example, one can write +

+homs ’t_’
+  :: Lam  (+ bind x in t +)  
+
+homs ’t_’
+  :: Var     {{ com variable }}         
+  :: Lam     {{ com abstraction }}      
+  :: App     {{ com application }}      
+  :: paren   {{ ich [[t]] }} 
+  :: tsub    {{ ich ( tsubst_t [[t]] [[x]] [[t’]] ) }}
+
+homs ”
+  :: reduce  {{ com [[t1]] reduces to [[t2]] }} 
+

+Each of these begins with a prefix and then has a sequence of +production name or definition name kernels, each followed by a +sequence of bindspecs and then a sequence of homomorphisms.

The test10_homs.ott example, in Fig. 16, shows this. It +is semantically equivalent to the test10.ott example of +Fig. 8, but the homs have been moved into hom +blocks. +


+
+

20  Isabelle syntax support

Ott has limited facilities to allow the Isabelle mixfix syntax support +and xsymbol to be used. The example test10_isasyn.ott shows +this in use. +

Non-meta productions can be annotated with +isasyn and/or isaprec homomorphisms. +For example, test10_isasyn.ott contains the production +

+  | t t’      :: :: App   {{ isasyn [[t]]\<bullet>[[t’]] }}  {{ isaprec 50 }}
+

+The two homs are used to output the Isabelle syntax annotation in the +t_App clause of the datatype definition below. +

t = 
+   t_Var "termvar"  
+ | t_Lam "termvar" "t"  ("\<lambda> _ . _" 60)
+ | t_App "t" "t"  ("_\<bullet>_" 50)
+

+Definitions can be annotated with +isasyn and/or isaprec homomorphisms similarly, e.g. as below. +

+    defn
+    t1 –> t2 ::  :: reduce ::{{ isasyn [[t1]] —> [[t2]] }}  by 
+

+This generates syntax and translations blocks as below. +

inductive_set reduce :: "(t*t) set"
+and  "reduce'" :: "t => t =>  bool" ("_ ---> _" 50)
+where "(t1 ---> t2) ==  ( t1 , t2 ) : reduce"
+

+Symbolic terms in definitions are printed using any production or +definition syntax. This (especially with xsymbol turned on) makes the +current goal state during Isabelle proof development much more +readable.

Further, there is a command line option -isa_syntax true. If +this is set then the tool generates Isabelle syntax annotations from +the source syntax. For example, the source file production for the +t_Lam clause is +

+    | \ x . t             ::   :: Lam   {{ isaprec 60 }}
+

+and the terminals grammar contains a mapping from \ to \<lambda>: +

+  terminals :: ’terminals_’ ::=
+    | \                   ::   :: lambda  {{ tex \lambda }}  {{ isa \<lambda> }}
+    | –>                 ::   :: red     {{ tex \longrightarrow }} {{ isa —> }}
+

+This is used (just as for LaTeX homs) to generate the ("\<lambda> _ . _" 60) +in the datatype definition above.

This functionality is limited in various ways: +(1) the full range of Isabelle precedence and associativity +specifications are not supported; +(2) the automatically generated syntax annotations are somewhat crude, +especially w.r.t. spacing and parenthesisation; +(3) syntax annotation on meta productions is not propertly supported; +and +(4) it would be desirable to have more fine-grain control of whether +to automatically generate annotations: per-production, per-rule, and +per-file.

+

21  Isabelle code generation example

The Isabelle/Coq/HOL code generation facilities can be sometimes used to +generate (variously) OCaml and SML code from the Isabelle/Coq/HOL +definitions produced by Ott.

For example, the test10st_codegen.thy file uses Isabelle +code generation to produce SML code to calculate the possible +reductions of terms in the test10st.ott simply typed lambda +calculus.

theory test10st_codegen 
+imports test10st_snapshot_out Executable_Set
+begin
+
+ML "reset Codegen.quiet_mode"
+
+(* Code generation for the test10st simply typed lambda calculus. *)
+
+constdefs
+ ta :: t
+"ta == (t_App (t_Lam ''z'' (t_Var ''z''))) (t_Lam ''y'' (t_Var ''y''))"
+;
+
+code_module Test10st_codegen file "test10st_codegen.ml" contains 
+(*is_v
+tsubst_T
+tsubst_t*)
+reduce_ta  = "(ta,_):reduce"
+
+
+(* ...to build and demo the resulting test10st_codegen.ml code...
+
+Isabelle test10st_codegen.thy
+...`use' that...
+
+...in a shell...
+isabelle
+use "test10st_codegen.ml";
+open Test10st_codegen;
+
+...a test term...
+ta;
+val it = t_App (t_Lam (["z"], t_Var ["z"]), t_Lam (["y"], t_Var ["y"]))
+
+...a sample reduction...
+DSeq.hd(reducep__1 ta);
+val it = t_Lam (["y"], t_Var ["y"]) : Test10st_codegen.t 
+
+*)
+
+end
+
+

22  Reference: Command-line usage

A good place to get started is one of the test +make targets in the ott directory, e.g. +

test10: tests/test10.ott
+           bin/ott                                                \
+                  -i tests/test10.ott                             \ 
+                  -o out.thy -o out.v -o outScript.sml            \
+                  -o out.tex                                      \
+                  -parse ":t:  (\z.z z) y"                        \                  
+           && ($(LATEX) out; $(DVIPS) out -o)
+

When make test10 is executed, ott: +

  • +reads the source file tests/test10.ott +
  • (if one also specifies -show_post_sort true and -show_defns +true) prints on standard output various diagnostic information, +including ASCII versions of the grammar and +inductive definitions. +By default these are coloured (using +vt220 control codes) with metavariables in red, nonterminals +in yellow, terminals in green, and object variables in white. +Scanning over this output quickly picks up some common errors. +
  • parses the symbolic term (\z.z z) y using the t +grammar and prints the result to standard output +
  • generates Isabelle definitions in the file out.thy +
  • generates Coq definitions in the file out.v +
  • generates HOL definitions in the file outScript.sml +
  • generates a LaTeX document in the file out.tex, with a +standard document preamble to make it self-contained. +

+That LaTeX document is then compiled and converted to postscript.

For convenience, input files can also be listed at the end of the command line: +

  ott [options] <file1> ... <filen>
+

is equivalent to +

  ott -i <file1> ... -i <filen> [options]
+

The %.out Makefile target runs ott with common +defaults on the file %.ott, so for example executing make tests/test10.out +runs ott on tests/test10.ott, generating all outputs. There are +also targets  %.coq.out,  %.hol.out, and + %.isa.out, to generate just LaTeX and the code for one proof +assistant, and  %.tex.out, to generate just LaTeX.

The ott command-line options (with default values where applicable) are +shown below. +

23  Reference: The language of symbolic terms

A syntax definition conceptually defines two different languages: that +of concrete terms of the object language, and that of symbolic terms +over the object language. +The former includes concrete variables (if nontrivial lex homs +have been specified for metavariables). +The latter includes the former but also +allows symbolic metavariables and nonterminals. +Symbolic terms may also include the production-name +annotations mentioned in §3. +For a syntax definition with list forms (c.f. §12) symbolic +terms also include various list constructs. +A simplified abstract syntax of symbolic terms is shown in +Figure 17, omitting list forms. In this section we give an +informal definition of the full concrete syntax of symbolic terms. +


+
+
Figure 17: Mini-Ott in Ott: symbolic terms
+

The premises and conclusions of inductive definition rules are +symbolic terms. +The language of symbolic terms is defined informally below, with interpretation functions [[_]] that map defined entities into grammar clauses.

For a rule rule   = +

+
nontermroot1   ,   ..   ,   nontermrootn ::   ’’   ::=   prod1   ..   prodm 

+we have +

+
+ + + + +
 [[rule]]::= 
 |nontermroot suffix(1) 
 |[[prod1]] 
 |..  
 |[[prodm]] 

(1) for each nontermroot in the set +{nontermroot1   ,   ..   ,   +nontermrootn } +and for each nontermroot defined by any rule′ +which is declared as a subrule of this rule.

For a production prod   = +

+
|   element1   ..   elementm   ::   ::   prodname

+we have +

+
+ + +
 [[prod]]::= 
 |[[element1]]   ..   [[elementm]] 
 |:prodname:  [[element1]]   ..   [[elementm]] 

For an element there are various cases. +

  1. +For a terminal terminal + +
    +
     [[terminal]]::=terminal
    +
  2. For a nonterminal nontermroot   suffix + +
    +
     [[nontermroot   suffix]]::=[[rule]] 
    +where rule includes nontermroot among the +nonterminal roots it defines. (Note that this does not depend on what suffix was used in the grammar, and similarly for the metavar case below.)
  3. For an index variable indexvarroot + +
    +
     [[indexvarroot]]::=indexvarroot
    +for each indexvarroot′ defined by the indexvar +definition that defines indexvarroot.
  4. For a metavariable metavarroot   suffix + +
    + + +
     [[metavarroot   suffix]]::= 
     |metavarroot′ suffix(1) 
     |variable 
    +(1) for each metavarroot′ defined by the metavar +definition that defines metavarroot. +(2) where variable ranges over all the strings defined by +the lex regexp of the metavar +definition that defines metavarroot, except for any string +which can be parsed as a nonterminal, metavariable or terminal of the syntax +definition. +
  5. A list form element element could be any of the following, either without a separating terminal: + +
    + + + + +
    element1 .. elementn  +  dots   +element1 .. elementn 
    </  element1 .. elementn   //   indexvar   /> 
    </  element1 .. elementn   //   indexvar   IN   indexvar′   /> 
    </  element1 .. elementn   //   indexvar   IN   number   dots   indexvar′   /> 
    </  element1 .. elementn   //   indexvar   IN   number   dots   indexvar-1   /> 
    +or with a separating terminal: + +
    + + + + +
    element1 .. elementn  +  terminal   dots   terminal   +element1 .. elementn 
    </  element1 .. elementn   //  terminal //  indexvar   /> 
    </  element1 .. elementn   //  terminal //  indexvar   IN   indexvar′   /> 
    </  element1 .. elementn   //  terminal //   indexvar   IN   number   dots   indexvar′   /> 
    </  element1 .. elementn   //  terminal //   indexvar   IN   number   dots   indexvar-1   /> 
    +In any of these cases the interpretation [[element]] is the lists (separated by the terminal if one was specified) of concrete list entries and of list forms. +Without a separating terminal, this is: + +
    + + + + + + + + + +
     [[element]]::=(concrete_list_entry | list_form)*(2), (3)
     
    concrete_list_entry::=[[element1]]   ..   [[elementn]] 
     
    list_form::= 
     |[[element1]]   ..   [[elementn]]  + dots′  +[[element1]]   ..   [[elementn]](1) 
     |</  [[element1]] .. [[elementn]]   //  indexvar″   /> 
     |</  [[element1]] .. [[elementn]] //  indexvar″   IN   indexvar‴   /> 
     |</  [[element1]] .. [[elementn]] //   indexvar″   IN   number′   dots′   indexvar‴   /> 
     |</  [[element1]] .. [[elementn]] //   indexvar″   IN   number′   dots′   indexvar-1   /> 
    +This is subject to constraints: (1) that +[[element1]]   ..   [[elementn]] +and +[[element1]]   ..   [[elementn]] can be +anti-unified with exactly one varying index; (2) if the list has only +concrete entries (i.e., no list forms), its length must meet +the constraint of any dots in the +element.

    With a separating terminal, we have: +

    +
    +
     [[element]]::=є | (concrete_list_entry | list_form) +(terminal (concrete_list_entry | list_form))*

In the above +

+
+ + + + + + + + +
dots::=.. | ... | .... 
number::=0 | 1  
suffix::=suffix_item* 
suffix_item::= 
 |(0 | 1 |2 | 3 |4 | 5 |6 | 7 |8 | 9)+(longest match) 
 |_ 
 | 
 |indexvar 
 |indexvar-1 

Further, whitespace (' '|'\010'|'\009'|'\013'|'\012') is allowed before any token except a those in a suffix, and nonterminals, metavariables, index variables, and terminals that end with an alphanumeric character, must not be followed by an alphanumeric character.

The tool also builds a parser +for concrete terms, with fake nonterminal roots concrete_ntr +for each primary ntr of the syntax definition. One can +switch to concrete-term parsing with a :concrete: annotation, +as in the example +

\[ [[ :concrete: \Z1<:Top. \x:Z1.x ]]\]
+

+shown in Figure 10. Below such an annotation, only concrete terms +are permitted, with no further annotation, no symbolic nonterminals or +metavariables, no list dot forms or comprehensions, etc.

Parsing of terms is done with a scannerless GLR parser over character-list +inputs. The parser +searches for all parses of the input. If none are found, the ASCII +and TeX output are annotated no parses, with a copy of the +input with *** inserted at the point where the last token was +read. This is often at the point of the error (though if, for +example, a putative dot form is read but the two element lists cannot +be anti-unified, it will be after the point of the error). +If multiple parses are found, the TeX output is annotated +multiple parses and the different parses are output to the +console in detail during the Ott run.

The GLR parser +achieves reasonable performance on the small symbolic terms that are +typical in semantic rules. Its performance on large (whole-program +size) examples is untested.

24  Reference: Generation of proof assistant definitions

This section briefly summarises the steps involved in the generation +of proof assistant definitions from an Ott source file. For a description of the locally-nameless backend, refer to http://moscova.inria.fr/ zappa/projects/ln_ott/. +

+

24.1  Generation of types

  • +The primary metavariable roots and primary nonterminal roots are used +directly as the names of proof assistant types, except where they +have a hom specifying a root-overriding string. +
  • Type abbreviation declarations are produced for metavars, in the +source-file order, skipping metavars or nonterminals defined with phantom. +
  • Type generation considers each rule of the user’s source grammar +except those for formula and terminals (or the +synthesized rules for the syntax of judgements or user_syntax). +
  • The subrule order is analysed to identify the top elements. For +each of those, a proof assistant type will be generated — either a +free type (coq: inductive, isa: +datatype, hol: Hol_datatype), or if there is a +type hom for the proof assistant in question, a type abbreviation. +No types are generated for the non-top elements, as they will be +represented as predicates over the top free type above them. +
  • For the former, each non-meta production of the rule +gives rise to a constructor. The production name (with any per-rule +prefix already applied) is used directly as the constructor name. +The (curried) constructor argument types are taken from the +types associated with the metavariables and nonterminals mentioned +in the production body. +
  • Rules (within each grammar block, if -merge +false, or all rules, if -merge true) are topologically sorted according to the dependency order +(a free-type rule directly depends on another if one of its non-meta +productions includes a nonterminal of the other; dependencies for rules with a type-hom +for the proof assistant in question +are obtained from a crude lexing of the body of the type hom). +We then generate mutually recursive type +definitions for connected components, in an order consistent with +the dependencies. +
  • For productions that involve list dot forms or list comprehension +forms, for HOL and Isabelle we produce constructors with argument +types that involve native list types. For Coq, however, we +synthesise an additional inductive type for each list-of-tuples that arises +(both for those that occur in the grammar and for others required in +the translations of inductive definitions) and include them in the +topological sort. +
+

24.2  Generation of functions

+A small number of library functions (list_mem, +list_minus,...) are included in the output if they are +required.

Several Coq list functions (map, make, unmake, nth, app) are generated +for each synthesized list type.

The definitions of the more interesting functions (subrule predicates, +binding auxiliaries, free variable functions, and substitutions) are +generated over the free types generated for the maximal elements of the +subrule order (generation of these functions for rules with type homs +is not supported). The definitions are by pattern-matching and +recursion. +The patterns are generated by building canonical symbolic terms from +the productions of each relevant rule. +The recursion is essentially primitive recursion: +for Coq we produce Fixpoints or Definitions +(the latter is sometimes needed as the former gives an error in the case where there is no +recursion); +for Isabelle we produce primrecs (or, experimentally, funs); +for HOL we use an ottDefine variant of the Define +package. +In general we have to deal both with the type dependency +(the topologically sorted mutually recursive types described above) +and with function dependency — for example, for subrule predicates +and binding auxiliaries we may have multiple mutually recursive +functions over the same type.

For Coq the function generation over productions that involve list +types must mirror that, so we generate auxiliary functions +that recurse over those list types.

For Isabelle the primrec package does not support +definitions involving several mutually recursive functions over the +same type, so for these we generate single functions calculating +tuples of results, define the intended functions as projections of +these, and generate lemmas (and simple proof scripts) characterising +them in terms of the intended definitions. +Further, it does not support pattern matching involving nested +constructors. We therefore generate auxiliary functions for +productions with embedded list types. Isabelle tuples are treated as +iterated pairs, so we do the same for productions with tuples of size +3 or more. +Isabelle also requires a function definition for each recursive type. +In the case where there are multiple uses of the same type +(e.g. several uses of t list in different productions) all the +functions we wish to generate need identical auxiliaries. As yet, the +tool does not generate the identical copies required.

If the option -isabelle_primrec is set to false, then +Ott uses the fun package instead of the primrec package. +Since at the time of writing Isabelle 2008 is not capable of proving +automatically termination of all the funs that Ott generates, +this feature should be considered experimental.

For HOL the standard Define package tries an automatic +termination proof. For productions that involve list types +our generated functions involve various list functions which prevent +those proofs working in all cases. +We therefore use an ottDefine variant (due to Scott Owens), +with slightly stronger support for proving termination of +definitions involving list operators.

+

24.2.1  Subrule predicates

We generate subrule predicates to carve out the subsets of each free +proof assistant type (from the maximal elements of the subrule order) +that represent the rules of the grammar. +The non-free rules are the least subset of the rules that either +(1) occur on the left of a subrule (<::) declaration, or +(2) have a (non-meta) production that mentions a non-free rule. +Note that these can include rules that are maximal elements of the +subrule order, e.g. if an expression grammar included a production +involving packaged values. +The subrule predicate for a type is defined by pattern matching over +constructors of the maximal type above it — for each non-meta +production of the maximal type it calculates a disjunction +over all the productions of the lower type that are subproductions of +it, invoking other subrule predicates as appropriate.

+

24.2.2  Binding auxiliaries

+The binding auxiliary functions calculate the intuitive semantics of auxiliary functions defined in bindspecs of the Ott source file. Currently these are represented as proof assistant lists of metavariables or nonterminals (arguably set types should be used instead, at least in Isabelle).

+

24.2.3  Free variables

+The free variable functions simply walk over the structure of the free proof assistant types, using any bind specifications (and binding auxiliaries) as appropriate. +For these, and for substitutions, we simplify the generated functions by using the dependency analysis of the syntax to exclude recursive calls where there is no dependency.

+

24.2.4  Substitutions

+The generated substitution functions also walk over the structure of the free proof assistant types. +For each production, for each occurrence of a nonterminal nt within it, we first calculate the things (of whatever type is in question) binding in that nt, i.e. those that should be removed from the domain of any substitution pushed down into it. There are two cases: +(1) the mse' from any bind mse' in nt; +(2) nt itself if it occurs in the mse'' of any bind mse'' in nt'', i.e.  +nt itself if it is directly used to bind elsewhere. +List forms within bindspecs are dealt with analogously. +

The substitution function clause for a production is then of one of two forms: +either (1) the production comprises a single element, of the nonterminal or metavariable that we are substituting for, and this is within the rule of the nonterminal that it is being replaced by, or (2) all other cases. +For (1) the element is compared with the domain of the substitution, and replaced by the corresponding value from the range if it is found. +For (2) the substitution functions are mapped over the subelements, having first removed any bound things from the domain of the substitution.

This is all done similarly, but with differences in detail, for single and for multiple substitutions.

+

24.3  Generation of relations

+The semantic relations are defined +with the proof-assistant inductive relations packages +(coq: Inductive, +isa: inductive, +hol: Hol_reln). +They use the mutual recursion structure that is given by the user, +with each defns block giving rise to a potentially mutually +recursive definition of each defn inside it. +(It is debatable whether it would be preferable to do an automatic dependency analysis and topological sort, as for the syntax.) +Each definition rule gives rise to an implicational clause, essentially +that the premises (Ott formulas) imply the conclusion (an Ott symbolic term of whichever judgement is being defined). +In addition: +

  • +Symbolic terms are transformed in various different ways: +
    • +Nodes of non-meta productions are output as applications of the appropriate proof-assistant constructor (and, for a subrule, promoted to the corresponding constructor of a maximal rule). +
    • Nodes of meta productions are transformed with the user-specified homomorphism. +
    • Nodes of judgement forms are represented as applications of the defined relation in Coq and HOL, and as set-membership assertions in Isabelle. +
    • Lists of formulae (the formula_dots production) are special-cased. +
    +
  • For each nonterminal of a non-free syntax rule (as in §24.2.1) that occurs, +e.g. a usage of v' where v<::t, an additional premise invoking the subrule predicate for the non-free rule is added, e.g. is_v v'. +
  • The set of symbolic terms of the definition rule are analysed together to identify list forms with the same bounds. A single proof assistant variable is introduced for each such, with appropriate projections and list maps/foralls at the usage points. +
  • For Coq, auxiliary defined relations are introduced for list forms. +
  • For Coq, as the projections from list forms involve (Ott-generated) nth functions that return option types, for any such projection a pattern-match against Some is introduced as an additional premise. +
  • For Coq and HOL, explicit quantifiers are introduced for all variables mentioned in the rule. +
+

Ott

+

+ Francesco Zappa Nardelli, + Peter Sewell, and + Scott Owens +

+

(with + Matthew Parkinson, + Gilles Peskine, + Tom Ridge, + Susmit Sarkar, and + Rok Strniša) +

+

+Ott is a tool for writing definitions of programming languages and +calculi. It takes as input a definition of a language syntax and +semantics, in a concise and readable ASCII notation that is close to +what one would write in informal mathematics. It generates LaTeX to +build a typeset version of the definition, and Coq, HOL, and Isabelle +versions of the definition. Additionally, it can be run as a filter, +taking a LaTeX/Coq/Isabelle/HOL source file with embedded (symbolic) +terms of the defined language, parsing them and replacing them by +target-system terms. +For a simple example, here is an +Ott source file for an untyped call-by-value +lambda calculus (test10.ott), and +the generated +LaTeX (compiled to pdf) +and (compiled to ps), +Coq, +Isabelle, and +HOL +definitions. +

+Most simply, the tool can be used to aid completely informal LaTeX mathematics. +Here it permits the definition, and terms within proofs and +exposition, to be written in a clear, editable, ASCII notation, without LaTeX +noise. It generates good-quality typeset output. +By parsing (and so sort-checking) this input, it quickly catches a +range of simple errors, e.g. inconsistent use of judgement forms or +metavariable naming conventions. +

+That same input can be used to generate formal definitions, for Coq, +HOL, Isabelle, and (experimentally) Lem. It should thereby enable a smooth transition +between use of informal and formal mathematics. Additionally, the +tool can automatically generate definitions of functions for free +variables, single and multiple substitutions, subgrammar checks +(e.g. for value subgrammars), and binding auxiliary functions. +At present only a fully concrete representation of binding, without +quotienting by alpha equivalence, is fully supported. An experimental +backend generates a locally-nameless representation of terms for a +subset of the Ott metalanguage: details can be +found here. +

+The distribution includes several examples, in varying levels of completeness: +untyped and simply typed lambda-calculus, +a calculus with ML polymorphism, +the POPLmark Fsub with and without records, +an ML module system taken from (Leroy, JFP 1996) and equipped with an +operational semantics, and +LJ, a lightweight Java fragment. +More substantially, Ott has been used for work on +iJAM and LJAM, Java Module + Systems, by Rok + Strniša, and semantics for +OCaml light, by + Scott Owens. +

+A release of the Ott source is available, and comment and +feedback would be much appreciated. +

Pure FreshML relies on a rich binding + specification language, on user-provided assertions, expressed in a logic that + allows reasoning about values and about the names that they contain, and on a + conservative, automatic decision procedure for this logic.

definitions of programming languages and +calculi. +% +It takes as input a definition of a language syntax and semantics, in +a concise and readable ASCII notation that is close to what one would +write in informal mathematics. It generates output: +\begin{enumerate} +\item a \myLaTeX{} source file that defines commands to build a typeset version of + the definition; +\item a Coq version of the definition; +\item a HOL version of the definition; +\item an Isabelle/HOL version of the definition; +\item a Lem version of the definition; +\item an OCaml version of the syntax of the definition. +\end{enumerate} +Additionally, it can be run as a filter, taking a +\myLaTeX{}/Coq/Isabelle/HOL/Lem/OCaml source file +with embedded (symbolic) terms of the defined language, parsing them and replacing +them by typeset terms. + + +This document is a user guide for the tool.

The project web page +\begin{quotation} +\ahrefurl{http://www.cl.cam.ac.uk/users/pes20/ott/} +\end{quotation} +links to the github source repository, with a +BSD-style licence. It also has a range of examples, including +untyped and simply typed CBV lambda calculus, ML polymorphism, various +first-order systems from Pierce's TAPL~\cite{Pierce:TypeSystems}, the +POPLmark F$_{<:}$ language~\cite{poplmark}, a module system by +Leroy~\cite[\S4]{Leroy-generativity} (extended with a term language and an +operational semantics), the LJ Java fragment and LJAM Java module +system~\cite{ljam-sub}, and a substantial fragment of OCaml. + + + +Our main goal is to support work on large programming language +definitions, where the scale makes it hard to keep a definition +internally consistent, and hard to keep a tight correspondence between a +definition and implementations. +% +We also wish to ease rapid prototyping work with smaller calculi, +and to make it easier to exchange definitions and definition fragments +between groups. +% +% +Most simply, the tool can be used to aid completely informal \myLaTeX{} mathematics. +Here it permits the definition, and terms within proofs and +exposition, to be written in a clear, editable, ASCII notation, without \myLaTeX{} +noise. It generates good-quality typeset output. +By parsing (and so sort-checking) this input, it quickly catches a +range of simple errors, e.g.~inconsistent use of judgement forms or +metavariable naming conventions. +% +That same input, extended with some additional data, can be used to generate formal definitions for +Coq, HOL, Isabelle, and Lem. It should thereby enable a smooth transition +between use of informal and formal mathematics. Further, the +tool can automatically generate definitions of functions for free +variables, single and multiple substitutions, subgrammar checks +(e.g.~for value subgrammars), and binding auxiliary functions. +Ott supports a `fully concrete' representation, sufficient +for many examples but not dealing with general alpha equivalence. +An experimental Coq backend generates definitions in locally-nameless style for a subset of the Ott metalanguage. + The OCaml backend +generates type definitions that may be useful for developing a complete +implementation of the language, together with the functions listed +above. It does not generate anything for inductively defined relations +(the various proof-assistant code extraction facilities can +sometimes be used for that). +% +Our focus here is on the problem of writing and editing language +definitions, not (directly) on aiding mechanized proof of metatheory. If one +is involved in hard proofs about a relatively stable small calculus +then it will aid only a small part of the work (and one might choose +instead to work just within a single proof assistant), but for larger +languages the definition is a more substantial problem --- so much so +that only a handful of full-scale languages have been given complete definitions. We +aim to make this more commonplace, less of a heroic task. + +% getting started with Ott +\input{README} + + +\section{A minimal Ott source file: the untyped CBV lambda calculus}\mlabel{a51}% +Fig.~\ref{a45} shows an Ott source file for an untyped call-by-value +(CBV) lambda calculus. This section explains the basic features that +appear there, while in the following sections we show what must be +added to generate typeset output, proof assistant definitions, and +other things. +\begin{figure} +\fbox{\small\begin{minipage}{\textwidth} +\input{test10.0.alltt} +\end{minipage}} +\caption{Source: \texttt{test10.0.ott}\protect\label{a45}} +\end{figure} +The figure is colourised, with Ott keywords like \mykw{this} and Ott +symbols such as \mysym{|} and \mysym{::}. Other user-specific input +appears like \texttt{this}. + +At the top of the figure, the \mykw{metavar} declaration introduces +a sort of \emph{metavariables} \texttt{termvar} (with synonym \texttt{x}), for term +variables. +% +The following \mykw{grammar} introduces two grammar rules, one for terms, with + \emph{nonterminal root} + \texttt{t}, and one for values \texttt{v}. +This specifies the concrete syntax of object-language terms, +the abstract syntax representations for proof-assistant mathematics, +and the syntax of symbolic terms to be used in semantic rules. + +Each rule has a rule name prefix (e.g.~\texttt{'t\_'}) and then a list +of productions. Each production, e.g. +\begin{alltt} + \mysym{|} \mybackslash{} x . t \mysym{::} \mysym{::} Lam +\end{alltt} +specifies a syntactic form as a list of elements, here `\verb+\+', +`\verb+x+', `\verb+.+', and `\verb+t+', each of which is either a +metavariable (the `\verb+x+'), a nonterminal (the `\verb+t+'), or a +terminal +(\texttt{\mybackslash} \texttt{.} \texttt{(} \texttt{)} \texttt{\mylb} \texttt{\myrb} \texttt{/} \texttt{-->}). +% +Within productions all elements must be whitespace-separated, so that +the tool can deduce which are terminals. In the symbolic terms in +the semantic rules below, however, whitespace is required only where necessary. +%Terminals are not required to be declared in the \texttt{terminals} +%grammar (all strings that are not metavariables or nonterminals are +%regarded as terminals) but, if they are, then \myLaTeX{} pretty printing +%information for them can be specified there. In this example the +%`\verb+\+' is included in the \texttt{terminals} grammar and will be +%\myLaTeX pretty printed as a $\lambda$, whereas the `\verb+.+' is not +%included and will be pretty printed in a default form. +A few terminals have to be quoted (with \verb+''+) if they appear in a grammar, e.g. to +use \texttt{|} as an object-language token, as they are part of the Ott syntax, but they +do not have to be quoted at usage points. +% +(If one accidentally omits inter-token whitespace in the grammar, the +output of Ott can be surprising. This is best diagnosed by looking at +the colourised ASCII or \myLaTeX{} output from Ott.) + +Metavariables and nonterminals can be formed from the specified +metavariable and nonterminal roots by appending a suffix, e.g.~the +nonterminal \verb+t'+ in the \verb+App+ and \verb+Tsub+ productions. + + + + +Between the \mysym{::}'s is an optional meta flag \mykw{M} or \mykw{S}. Non-meta +productions give rise to clauses of datatype definitions in the +Isabelle/Coq/HOL output, whereas meta productions do not. Later, we +will see how the user can specify how meta syntax should be translated +away when generating proof assistant output. The two flags \mykw{M} +and \mykw{S} are identical except that productions with the latter are +admitted when parsing example concrete terms; the \mykw{S} tag is thus +appropriate for lightweight syntactic sugar, such as productions for +parentheses. One can also use an \mykw{X} flag here to suppress a +production in the generated LaTeX. + +Each production has a production name (e.g.~\verb+t_Lam+), composed of +the rule name prefix (here~\verb+t_+) and the production name kernel +that follows the \mysym{::}'s (here~\verb+Lam+). The production name is +used as a constructor name in the generated Isabelle/Coq/HOL. + +The tool supports arbitrary context-free grammars, extended with +special constructs for list forms (c.f.~\S\mref{a61}). + + +Following the \mykw{grammar} in this example is a \mykw{subrule} +declaration +\begin{alltt} + \mykw{subrules} + v \mysym{<::} t +\end{alltt} +declaring that the \verb+v+ grammar rule (of values) is a +subgrammar of the \verb+t+ rule (of terms). The tool checks that +there is in fact a subgrammar relationship, i.e.~that for each +production of the lower rule there exists a production of the higher +rule with corresponding elements (up to the subrule relation). +The subrule declaration means that, in the semantic rules below, we +will be able to use \verb+v+'s in places where the grammar specifies \verb+t+'s. +In the generated Isabelle/Coq/HOL for this example only one free +datatype will be generated, for the \verb+t+ rule, while for the \verb+v+ +rule we generate an \verb+is_v+ predicate over the \verb+t+ type. Usages of +\verb+v+ nonterminals in the semantic rules will have instances of this +predicate automatically inserted. + +Finally, we give a collection of definitions of inductive relations. +In this example there is just one family of definitions (of +operational judgements), introduced by the \mykw{defns} \verb+Jop+; it contains just one +definition of a relation, called \verb+reduce+. +In general there may be many \mykw{defns} blocks, each of which introduces a +mutually recursive collection of \mykw{defn}s. +The relation definition +\mykw{defn}\verb+ ...+ +also includes a grammar production specifying how elements of the +relation can be written and typeset, here +\begin{verbatim} + t1 --> t2 +\end{verbatim} +As in the main grammar, the tokens of this syntax definition in the +header must be space-separated, but usages of the syntax generally +need not be. +Syntax rules for each family of +judgements, and for their union, are implicitly generated. +The relation definition is given by a sequence of inference rules, +each with a horizontal line separating a number of premises from a +conclusion, for example as below. +\begin{alltt} + t1 --> t1' +\mysym{ -------------- ::} ctx_app_arg + v t1 --> v t1' +\end{alltt} +The conclusion must be a symbolic term of the form of the judgement being +defined. +In simple cases (as here) the premises can be symbolic terms of the +form of any of the defined judgements. More generally (see +\S\ref{a53}) they can be symbolic terms of a user-defined +\mykw{formula} grammar, or in-line embedded prover code. +Each rule + has a name, composed of a definition family prefix +(here empty), a definition prefix (here also empty) and a kernel +(the~\verb+ctx_app_arg+). +% + + + + +The symbolic terms in semantic rules are parsed with a scannerless parser, built +using parser combinators over character-list inputs. The parser +searches for all parses of the input. If none are found, the ASCII +and TeX output are annotated \texttt{no parses}, with a copy of the +input with \texttt{***} inserted at the point where the last token was +read. This is often at the point of the error (though if, for +example, a putative dot form is read but the two element lists cannot +be anti-unified, it will be after the point of the error). +If multiple parses are found, the TeX output is annotated +\texttt{multiple parses} and the different parses are output to the +console in detail during the Ott run. +% +If the option \texttt{picky\_multiple\_parses} is set to +\texttt{true}, multiple parses are always reported. If it set to +\texttt{false}, a symbolic term is considered ambiguous only if two +different parses compile to different strings (for a target). +% +The parser combinators use memoization and continuation-passing to +achieve reasonable performance on the small symbolic terms that are +typical in semantic rules. Their performance on large (whole-program +size) examples is untested. +% +To resolve ambiguity one can add metaproductions for parentheses (as +in Fig.~\mref{a45}), or +production-name annotations in particular symbolic terms, +e.g.~the \verb+:t_tsub:+ in the \verb+AppAbs+ rule of the POPLmark +example, +\texttt{test7.ott}. %\S\mref{a27}. + There is currently no support for precedence +or associativity. + + +This file is included in the distribution as +\texttt{tests/test10.0.ott}. It can be processed by executing +\begin{alltt} + bin/ott -i tests/test10.0.ott +\end{alltt} +from the main directory. This simply reads in the file, checking that +it is well-formed. Adding options: +\begin{alltt} + bin/ott -show\_sort true -show\_defns true -i tests/test10.0.ott +\end{alltt} +it echos a colourised version to the screen, +with metavariables in red, nonterminals + in yellow, terminals in green, and object variables in white. +The colourisation uses vt220 control codes; if they do not work on +your screen add \texttt{-colour false} to the middle of the command +line. To suppress the echo of the definition, add +\texttt{-show\_post\_sort false} and \texttt{-show\_defns false}. + + +\subsection{Index variables} +In addition to the \mykw{metavar} declarations above, the user can declare any number of distinguished \emph{index} +metavariables, e.g. by: +\begin{alltt} + \mykw{indexvar} index\mysym{,} i\mysym{,} j\mysym{,} n\mysym{,} m \mysym{::=} \mysym{\mylb\mylb{}} \mykw{isa} num \mysym{\myrb\myrb{}} \mysym{\mylb\mylb{}} \mykw{coq} nat \mysym{\myrb\myrb{}} \mysym{\mylb\mylb{}} \mykw{hol} num \mysym{\myrb\myrb{}} +\end{alltt} +Given such a declaration, \verb+index+, \verb+i+, \verb+j+, \verb+n+ +and \verb+m+ can be used in suffixes, e.g.~in the production +\begin{alltt} + \mysym{|} ( t1 , \mysym{....} , tn ) \mysym{::} \mysym{::} Tuple +\end{alltt} +There is a fixed ad-hoc language of suffixes, including numbers, primes, and index variables (see \S\mref{a17}). +Index metavariables cannot themselves be suffixed. + + + + +\section{Generating \myLaTeX}\mlabel{a58}% +The example from the previous section can already be used to generate +\myLaTeX, for example by executing +\begin{alltt} + bin/ott -i tests/test10.0.ott -o out.tex +\end{alltt} +to produce a \myLaTeX{} file \texttt{out.tex}.

Here they +are typeset in math italic (which in fact is also the default). +Within the translation, the metavariable itself can be mentioned +inside double square brackets \texttt{\mysym{[[} }$\ldots$\texttt{ \mysym{]]}}. + +Secondly, there is a grammar for a distinguished nonterminal root +\mykw{terminals}, with a +\texttt{\mysym{\mylb\mylb{}} \mykw{tex} }$\ldots$\texttt{ \mysym{\myrb\myrb{}}} +translation for each, overriding the default typesetting of some +terminals.

Alternatively, the +program option \verb+-tex_wrap false+ with the \verb+-tex_wrap false+ +command-line argument, one can generate a file that can be included in +other \myLaTeX{} files, that just defines macros to typeset various +parts of the system (\verb+-tex_wrap false+ overrides any +\verb+tex-wrap-pre/tex-wrap-post+ embeds). + + +The generated \myLaTeX{} output is factored into individual \myLaTeX{} +commands: for the metavariable declarations, each rule of the syntax +definition, the collected syntax (\verb+\ottgrammar+), each rule of the inductive relation +definitions, the collected rules for each relation, the collected +rules for each \verb+defns+ block, the union of those +(\verb+\ottdefns+) and the whole (\verb+\ottall+). +% +This makes it possible to quote individual parts of the definition, +possibly out-of-order, in a paper or technical report. + + +If one needs to include more than one system in a single \myLaTeX{} +document, the \verb+ott+ prefix can be replaced using the +\verb+-tex_name_prefix+ command-line argument. + +The generated \myLaTeX{} is factored through some common style macros, +e.g.~to typeset a comment, a production, and a grammar. If necessary +these can be redefined in an \mykw{embed} block (see Section~\ref{a60}). +For example, the file \verb+tests/squishtex.ott+ +\input{squishtex.hand.alltt} +defines a more compact style for grammars. Note that the +\texttt{\mysym{[[}\mykw{TEX\_NAME\_PREFIX}\mysym{]]}} is replaced by whatever prefix is in force, +so such style files can be reused in different contexts. + +A more sophisticated \myLaTeX{} package \verb+ottlayout.sty+, providing fine control of how +inference rules and grammars should be typeset, is contained in the +\verb+tex+ directory of the distribution. It is described in the +manual therein. + + +\section{Generating proof assistant definitions}\mlabel{a52}% +To generate proof assistant definitions, for Coq, Isabelle, and HOL, +the minimal Ott source file of Section~\ref{a51}/Figure~\ref{a45} must +be extended with a modest amount of additional data, as shown in Figure~\ref{a47}. +Executing +\begin{alltt} + bin/ott -i tests/test10.4.ott -o out.v -o out.thy -o outScript.sml +\end{alltt} +generates Coq \texttt{out.v}, Isabelle \texttt{out.thy}, and HOL +\texttt{outScript.sml}, shown in Figures~\ref{a6}, \ref{a5}, and \ref{a40}. +The additional data can be combined with the annotations for +\myLaTeX{} of the previous section, but those are omitted here. +\begin{figure} +\fbox{\small\begin{minipage}{\textwidth} +\input{test10.4.alltt} +\end{minipage}} +\caption{Source: \texttt{test10.4.ott}\protect\label{a47}} +\end{figure} +We add four things. +First, we specify proof assistant types to represent object-language +variables --- in this example, choosing the \texttt{string} type of +Isabelle and HOL, and the \texttt{nat} type for Coq: +\begin{alltt} + \mykw{metavar} termvar\mysym{,} x \mysym{::=} + \mysym{\mylb\mylb{}} \mykw{isa} string\mysym{\myrb\myrb{}} \mysym{\mylb\mylb{}} \mykw{coq} nat\mysym{\myrb\myrb{}} \mysym{\mylb\mylb{}} \mykw{hol} string\mysym{\myrb\myrb{}} \mysym{\mylb\mylb{}} \mykw{coq-equality} \mysym{\myrb\myrb{}} +\end{alltt} +For Coq output, one can specify \verb+{{ coq-equality+ \textit{proof-script} \verb+}}+ +to build a decidable equality over the Coq representation type using +the proof \textit{proof-script}. If the script is omitted, as in this +example, it defaults +to +\begin{verbatim} +Proof. + decide equality; auto with ott_coq_equality arith. +Defined. +\end{verbatim} +where the \verb+ott_coq_equality+ database contains the decidable +equalities of the representation types defined in the source. It is +possible to suppress type generation for specific metavariables or nonterminals, by adding the +declaration \verb+{{ phantom }}+. This is useful in some cases, for +instance to avoid duplicate definitions of types already defined in an +imported library. Any type homs are taken into account when +the metavariable or nonterminal root is output as a type. + + +Second, we specify what the binding is in the object language, with +the \texttt{\mysym{(+} \mykw{bind} x \mykw{in} t \mysym{+)}} +annotation on the \texttt{Lam} production: +\begin{alltt} + \mysym{|} \mybackslash{} x . t \mysym{::} \mysym{::} Lam \mysym{(+} \mykw{bind} x \mykw{in} t \mysym{+)} +\end{alltt} +Section~\ref{a62} describes the full language of binding specifications. + +Third, we add a block +\begin{alltt} + \mykw{substitutions} + \mykw{single} t x \mysym{::} tsubst +\end{alltt} +to cause Ott to generate Coq/Isabelle/HOL definitions of a substitution +function, with name root \texttt{tsubst}, replacing metavariables \texttt{x} by terms \texttt{t}. This is for single +substitutions; multiple substitution functions (taking lists of +substitutand/substitutee pairs) can also be generated with the keyword +\mykw{multiple}. +Substitution functions are generated for all rules of the grammar for +which they might be required --- here, just over \verb+t+, with a +function named \verb+tsubst_t+. + +Finally, we specify translations for the metaproductions: +\begin{alltt} + \mysym{|} ( t ) \mysym{::} \mykw{S}\mysym{::} Paren \mysym{\mylb\mylb{}} \mykw{icho} \mysym{[[}t\mysym{]]} \mysym{\myrb\myrb{}} + \mysym{|} \mylb{} t / x \myrb{} t' \mysym{::} \mykw{M}\mysym{::} Tsub \mysym{\mylb\mylb{}} \mykw{icho} (tsubst_t \mysym{[[}t\mysym{]]} \mysym{[[}x\mysym{]]} \mysym{[[}t'\mysym{]]})\mysym{\myrb\myrb{}} +\end{alltt} +These specify that \texttt{(t)} should be translated into just the +translation of \texttt{t}, whereas + \texttt{\mylb{}t/x\myrb{}t'} should be translated into the +proof-assistant application of \texttt{tsubst\_t} to the translations +of \texttt{t}, \texttt{x}, and \texttt{t'}. +The (admittedly terse) \mykw{icho} specifies that these translations should be +done uniformly for Isabelle, Coq, HOL, and OCaml output. One can also +specify just one of these, writing +\texttt{\mysym{\mylb\mylb{}} \mykw{coq} }$\ldots$\texttt{\mysym{\myrb\myrb{}}}, +\texttt{\mysym{\mylb\mylb{}} \mykw{hol} }$\ldots$\texttt{\mysym{\myrb\myrb{}}}, +\texttt{\mysym{\mylb\mylb{}} \mykw{isa} }$\ldots$\texttt{\mysym{\myrb\myrb{}}}, or +\texttt{\mysym{\mylb\mylb{}} \mykw{ocaml} }$\ldots$\texttt{\mysym{\myrb\myrb{}}}, +or include several, with different translations for each. +There are also abbreviated forms \mykw{ich}, \mykw{ic}, \mykw{ch}, and \mykw{ih}. +The body of a proof assistant hom should normally include outer +parentheses, as in the \texttt{Tsub} hom above, so that it is +parsed correctly by the proof assistant in all contexts. + +\begin{figure} +\fbox{\small\begin{minipage}{\textwidth} +\verbatiminput{test10.despaced.v} +%\verbatiminput{test10.hand.edited.v} +\end{minipage}} +\caption{Generated Coq:\texttt{test10.v}\protect\label{a6}} +\end{figure} + +\begin{figure} +\fbox{\small\begin{minipage}{\textwidth} +\verbatiminput{test10.thy} +%\verbatiminput{test10.hand.edited.thy} +\end{minipage}} +\caption{Generated Isabelle:\texttt{test10.thy}\protect\label{a5}} +\end{figure} + +\begin{figure} +\fbox{\small\begin{minipage}{\textwidth} +\verbatiminput{test10Script.sml} +\end{minipage}} +\caption{Generated HOL:\texttt{test10Script.sml}\protect\label{a40}} +\end{figure} + + +\subsection{Proof assistant code for grammar rules} +The normal behaviour is to generate a free proof assistant type for +each (non-subrule, non-phantom) grammar rule. +For example, the Coq compilation for \texttt{t} here generates a free type with three +constructors: +\begin{verbatim} + Inductive term : Set := + | t_var (x:var) + | t_lam (x:var) (t:term) + | t_app (t:term) (t':term). +\end{verbatim} +(note that the metaproductions do not give rise to constructors). + +Remark: prior to version 0.20.2, the free type generated for Coq was +\begin{verbatim} + Inductive term : Set := + | t_var : var -> term + | t_lam : var -> term -> term + | t_app : term -> term -> term. +\end{verbatim} +but we found that trying to preserve the names specified by the user +is helpful later, when doing proofs. Whenever a clash is detected, or +for list forms, the wildcard \texttt{\_} is used. The old behaviour +can be obtained via the top-level option +\texttt{-coq\_names\_in\_rules false}. + +By default the order of the arguments to those constructors follows +the order in which they appear in the production. That can be +overridden with an \texttt{order} hom.

This is work-in-progress, and it is extensively documented in \ahrefurl{http://moscova.inria.fr/~zappa/projects/ln\_ott/}. +We intend in future to generate other representations, and in some +circumstances homs can be used to implement other representations directly. +For a reasonably wide variety of +languages, however, one can capture the intended semantics of whole programs in +this idiom, subject only to the condition that standard library +identifiers are not shadowed within the program, as the operational +semantics does not involve reduction under binders --- so any +substitutions are of terms which (except for standard library +identifiers) are closed. This includes the ML polymorphism example of +\texttt{test8.ott}. %\S\mref{a23}. +For languages which require a type +environment with internal dependencies, however, for example F$_{<:}$, this is +no longer the case. The POPLmark F$_{<:}$ example given in \texttt{test7.ott} +has a type system which disallows all shadowing, a property that is +not preserved by reduction. However, a correct translation of F$_{<:}$ is generated by the Coq locally-nameless backend, and can be found in \ahrefurl{http://moscova.inria.fr/~zappa/projects/ln\_ott/}. + +Further discussion of binding representations is in the Ott ICFP 2007 +paper and in a working draft +\begin{quotation}\noindent +Binding and Substitition.

It is possible to turn off the generation of definitions for +these such functions by writing the following directive early on in the source file: + +\begin{alltt} +\mykw{embed} \mysym{\mylb\mylb{}} \mykw{coq-lib} list_mem list_minus \mysym{\myrb\myrb{}} +\end{alltt} + +This instructs Ott to avoid generating definition for \verb+list_mem+ and +\verb+list_minus+, but to continue generating definitions for other functions +such as \verb+list_assoc+ and \verb+list_minus2+. + +\textbf{Note about }\verb+list_minus2+\textbf{:} +Instead of using the function \verb+list_minus2+, earlier versions of Ott +generated equivalent code based on \verb+list_filter+, which was more +difficult to reason about. For backwards compatibility, however, we provide the +command-line option \verb+-coq_use_filter_fn+ for generating a definition using +the older code pattern. + +\subsection{Correctness of the generated proof assistant code} +We have attempted to ensure that the proof assistant definitions +generated by Ott are well-formed and what the user would intend. This +is not guaranteed, however, for several reasons: (1) There may be name +clashes between Ott-generated identifiers and proof assistant built-in +identifiers (or, in pathological cases, even among different +Ott-generated identifiers). (2) In some cases we depend on automatic +proof procedures, e.g.~for HOL definitions. These work in our test +cases, but it is hard to ensure that they will in all cases. More +importantly, (3) the generation process is complex, so it is quite +possible that there is either a bug in Ott or a mismatch between the +user expectation and what the tool actually does. Ultimately one has +to read the generated proof assistant definitions to check that they +are as intended --- but typically one would do this in any case, many +times over, in the process of proving metatheoretic results, so we do +not consider it a major issue. + +\subsection{Using the generated proof assistant code} +% +Note added 2017-11-30: the following is out of date. + +Ott builds code for + +\begin{tabular}{ll} +Coq 8.3 & \ahrefurl{http://coq.inria.fr/} \\ +HOL 4 (the current svn version) & \ahrefurl{http://hol.sourceforge.net/}\\ +Isabelle/HOL (Isabelle 2011) & \ahrefurl{http://isabelle.in.tum.de/} +\end{tabular} + +Given proof assistant files in the top-level directory of the +distribution, as produced at the start of this section +(Coq \texttt{out.v}, Isabelle \texttt{out.thy}, and HOL +\texttt{outScript.sml}), the various proof assistants can be invoked as follows. + +\subsubsection{Coq} +First run +\begin{verbatim} + make +\end{verbatim} +in the \texttt{coq} directory of the distribution, to build the auxiliary files. +These include a core file (\verb+ott_list_core+) of definitions that +are used in Ott-generated output. +At present these are only required when Coq native lists are used. +There are also various lemmas (in +\verb+ott_list.v+) which may be useful; they can be made available with +\verb+Require Import ott_list.+ + +For batch mode run +\begin{verbatim} + coqc -I coq out.v +\end{verbatim} +where \verb+coq+ is the path to the \verb+coq+ directory of the distribution. + +The experimental locally-nameless backend requires the \verb+Metatheory+ library by Arthur Chargueraud, available from the project web page. + +\subsubsection{HOL} +First run +\begin{verbatim} + Holmake +\end{verbatim} +in the \texttt{hol} directory of the distribution, to build the auxiliary files. + + For +batch mode run +\begin{verbatim} + Holmake -I hol outTheory.uo +\end{verbatim} +% +where \verb+hol+ is the path to the \verb+hol+ directory of the distribution. +% +For interactive mode, run +\begin{verbatim} + hol -I hol +\end{verbatim} +inside an editor window (where the second \verb+hol+ is again the path +to the \verb+hol+ directory of the distribution), and in +another window view the \verb+outScript.sml+ file.

All other text is simply echoed. +% (except that strings of $n$ +%\verb+[+ or \verb+]+ characters, for $n\geq 3$, are shortened by $1$). + + +Typical usage for \myLaTeX{} would be something like this (from the \verb+Makefile+ +used to produce this document): +\begin{verbatim} +test7.tex: ../src/ott ../tests/test7.ott ../tests/test7tt.mng + cd ../src; make tmp_test7_clean.ott + ../src/ott \ + -i ../src/tmp_test7_clean.ott \ + -o test7.tex \ + -tex_show_meta false \ + -tex_wrap false \ + -tex_name_prefix testSeven \ + -tex_filter ../tests/test7tt.mng test7tt.tex +\end{verbatim} +The \verb+-tex_wrap false+ turns off output of the default \myLaTeX{} +document preamble, so the generated file \verb+test7.tex+ just contains +\myLaTeX{} definitions. +The \verb+-tex_name_prefix testSeven+ sets a prefix for the generated +\myLaTeX{} commands +(so the \myLaTeX{} definitions from multiple Ott source files can be +included in a single \myLaTeX{} document). +The \verb+-tex_filter+ argument takes two +filenames, a source and a destination. It filters the source file, +(roughly) replacing any string found within \verb+[[+ \verb+]]+ by +the tex pretty-print of its parse.

The type \texttt{var}, + together with decidable equality and several useful lemmas and + functions, is defined in the Metatheory library. + +In the current implementation, metavariables susceptible to be bound +in a symbolic term (eg.\ the \texttt{x} in the \texttt{term\_var} +production) must be the only element of the production. + +\item Binder metavariables are erased from productions + (eg.\ \texttt{term\_lam}), as in de Bruijn representation. +\end{enumerate} + +Ott automatically generates the appropriate \texttt{open} functions +and \texttt{lc} predicates to test if terms are locally-closed. The +other support functions for substitutions and free-variables +(\texttt{subst} and \texttt{fv}) are generated once the user declares +the relevant substitutions and freevars sections. + +Ott automatically compiles the symbolic terms that appear in rule +definitions into the appropriate terms in locally-nameless style. For +instance, the typing rule for the simply-typed lambda-calculus: + +\begin{alltt} + E,x:S |- t : T +\mysym{ ------------------} :: lambda + E |- \mybackslash{}x.t : S->T +\end{alltt} +is compiled into its locally-nameless representation: +\begin{alltt} +Inductive typing : env -> term -> type -> Prop := (* defn typing *) +| ... +| typing_lambda : forall (L:vars) (E:env) (t:term) (S T:type), + (forall x, x \mybackslash{}notin L -> typing (E & x ~ S) (open_term_wrt_term t (term_var_f x)) T) -> + typing E (term_lam t) (type_arrow S T). +\end{alltt} + +For that, Ott follows the algorithm below. For each rule, +\begin{enumerate} +\item for each nonterminal that appears in the rule, compute the + maximal set of binders under which it appears: for example, in the + rule lambda above, the maximal set of binders for the nonterminal \texttt{t} + is the singleton \texttt{x}, and it is empty for all the other nonterminals; +\item for each pair nonterminal / maximal binder set collected in + phase 1., go over all the occurrences of the nonterminal in the rule + and open them with respect to all the variables in the maximal + binding set except those under which this particular occurrence is + bound. In the example, this amounts to opening the occurrence of \texttt{t} + in the premise with respect to the metavariable \texttt{x}; +\item quantify using cofinite-quantification each metavariable that + has been used to open a nonterminal; +\item add hypothesis about local-closure to guarantee the invariant + that if a derivation holds, then the top-level terms involved are + locally-closed. +\end{enumerate} +In some cases the user may want a finer control on which nonterminals +are opened and with respect to which metavariables. Consider for +instance the CBV beta-reduction rule: +\begin{alltt} +\mysym{ --------------------------} :: ax_app + (\mybackslash{}x.t1) v2 --> \mylb{}v2/x\myrb{}t1 +\end{alltt} +A naive application of the algorithm described above would open the +right hand side occurrence of \texttt{t1} with respect to a +cofinitely-quantified \texttt{x}. Substitution should then be used to replace +the occurrences of \texttt{x} with \texttt{v2}, resulting in the awkward term +\begin{alltt} +reduce (term_app (term_lam t1) v2) (subst_term v2 x (open_term_wrt_term t1 (term_var_f x))) +\end{alltt} + +Instead, an idiomatic translation of CBV beta-reduction rule would +directly rely on the open function to substitute \texttt{v2} for the +bound occurrences of \texttt{x} in \texttt{t1}, as in: +\begin{alltt} +reduce (term_app (term_lam t1) v2) (open_term_wrt_term t1 v2) +\end{alltt} + +A special syntax for production homomorphisms allow the user to specify this translation: +\begin{alltt} + \mysym{|} \mylb{} t / x \myrb{} t' \mysym{::} \mykw{M} \mysym{::} tsub \mysym{\mylb\mylb{}} \mykw{coq} (t_subst_t \mysym{[[}t\mysym{]]}\mysym{[[}x t'\mysym{]]}) \mysym{\myrb\myrb{}} +\end{alltt} +In the homomorphism the nonterminal \texttt{t'} is referred to with +\texttt{\mysym{[[}x t'\mysym{]]}} instead of the usual +\texttt{\mysym{[[}t'\mysym{]]}}: the prefixed \texttt{x} specifies +that occurrences of \texttt{t'} should not be opened with respect to +the metavariable \texttt{x}.

The \texttt{\_} is replaced by the original +nonterminal root name. + +For example, given a grammar or metavariable \texttt{l} of source locations, one +might say +\begin{verbatim} +ntr :: 'NTR_' ::= {{ aux _ l }} + | ... +\end{verbatim} +to synthesise grammars \texttt{ntr\_aux} and \texttt{ntr} of unannotated and location-annotated +terms, the first with all the original productions and the second with a +single production +\begin{verbatim} + | ntr l :: :: NTR_aux. +\end{verbatim} +If the rule has an empty production name wrapper (eg with \texttt{''} in place +of \texttt{'NTR\_'}) then the production name is based on the original +nonterminal root, capitalised and with \texttt{\_aux} appended (eg \texttt{Ntr\_aux}), to +avoid spurious conflicts. + +An additional \texttt{auxparams} hom on rules lets the user add type +parameters to the generated OCaml output. + + +Generation of aux rules is controlled by a command-line option +\texttt{-generate\_aux\_rules}, which one might (eg) set to false +for latex output and true for OCaml output. + + +\section{Functions} + +Ott includes experimental support for writing function definitions. + As a simple example, consider the Ott file below: + +\begin{alltt} + \mykw{grammar} + n \mysym{::} 'n_' \mysym{::=} + | 0 \mysym{::} \mysym{::} Zero + | S n \mysym{::} \mysym{::} Succ + + \mykw{funs} + Add \mysym{::=} \mysym{\mylb\mylb{}} hol-proof ... \mysym{\myrb\myrb{}} + \mykw{fun} + n1 + n2 \mysym{::} n \mysym{::} add \mysym{\mylb\mylb{}} com a function of type num -> num -> num \mysym{\myrb\myrb{}} + \mykw{by} + 0 + n2 \mysym{===} n2 + S n1 + n2 \mysym{===} n1 + S n2 +\end{alltt} + +Here the \verb+add+ function is compiled into the following Coq code: + +\begin{alltt} + Fixpoint add (x1:num) (x2:num) : num:= + match x1,x2 with + | n_zero , n2 => n2 + | (n_succ n1) , n2 => (add n1 (n_succ n2) ) + end. +\end{alltt} + +More in detail, the + \mykw{fun} + n1 + n2 \mysym{::} n \mysym{::} add + \mykw{by} + declaration specifies: +\begin{itemize} +\item the name of the function: \verb+add+ +\item the symbolic term that defines the lhs: \verb-n1 + n2- +\item the non-terminal that defines the rhs: \verb+n+ +\end{itemize} + +The type of the arguments of the function is defined by the + non-terminals appearing in the lhs, the return type by the rhs + non-terminal (so \verb+num+ $\to$ \verb+num+ $\to$ \verb+num+ in the + above example). As side-effect, whenever a function of type + \verb+symb_term+ $\to$ \verb+nt+ is defined, a production + \verb+nt ::= symb_term+ is added to the definition of the + non-terminal \verb+nt+ (in the above example, the production + \verb-n1 + n2- is added to the grammar of \verb+num+). + +Functions are then defined by case analysis, where the lhs and the rhs +are separated by the reserved symbol \mysym{===}. + +The \mysym{\mylb\mylb{}} \verb+hol-proof+ \mysym{\myrb\myrb{}} hom + allows the specification of a termination proof, which is required by + Hol. Mutually recursive functions can be defined in the same + \mykw{funs} block, analogously to mutually recursive rule + definitions. + +\emph{Disclaimer:} the different treatment of partial functions by the + different provers can result in a function definition being compiled + correctly to one prover but not to others. + + + + +\section{Parsing Priorities} + +Symbolic terms that can have more than one parse tree are typically considered +erroneous; however, certain classes of parse trees are ignored in order to +support common idioms that are ambiguous. For example, the production +% +\[\Gamma ::= \Gamma_1, .., \Gamma_n\] +% +might be used to allow a list of typing contexts to be appended together, but +it is highly ambiguous. The following restrictions forbid many unwanted parses +that could otherwise occur. +% +\begin{itemize} +\item +All parses in which a nonterminal derives itself without consuming any input +are ignored. For example, in the production above, the list could otherwise be +of length one so that $\Gamma$ directly derives $\Gamma$ giving rise to a +vacuous cycle, and an infinite forest of parse trees. This restriction +ensures that only the tree without the vacuous cycle is considered. +\item +The parser for a list form ignores parses that unnecessarily break up the list +due to (direct or indirect) self reference. For example, +$\Gamma_1,\Gamma_2,\Gamma_3,\Gamma_4$ will not parse as a two element sequence +of two element sequences $(\Gamma_1,\Gamma_2),(\Gamma_3,\Gamma_4)$ given the +production above. +\item +%\textit{\large Experimental Feature:} +User supplied priority annotations in a \mykw{parsing} section rule out certain +trees as follows: +\begin{itemize} +\item +$\mathit{prodname}_1 \mysym{<=} \mathit{prodname}_2$: Parse trees where a +$\mathit{prodname}_1$ node is a child of a $\mathit{prodname}_2$ node are +ignored. +\item +$\mathit{prodname}_1~\mykw{right}~\mathit{prodname}_2$: Parse trees where a +$\mathit{prodname}_1$ node is the leftmost child of a $\mathit{prodname}_1$ +node are ignored. +\item +$\mathit{prodname}_1~\mykw{left}~\mathit{prodname}_2$: Parse trees where a +$\mathit{prodname}_2$ node is the rightmost child of a $\mathit{prodname}_1$ +node are ignored. +\end{itemize} +In addition to immediate children, these priority annotations also prohibit +parse trees where the forbidden child node occurs underneath a chain of +derivations from the specified parent when the chain does not consume any +input. +Figure~\ref{parsing_figure} demonstrates a typical use of a \mykw{parsing} +section;

For a description of the locally-nameless backend, refer to \ahrefurl{http://moscova.inria.fr/~zappa/projects/ln\_ott/}. +\subsection{Generation of types} +\begin{itemize} +\item The primary metavariable roots and primary nonterminal roots are used + directly as the names of proof assistant types, except where they + have a hom specifying a root-overriding string. +\item Type abbreviation declarations are produced for metavars, in the + source-file order, skipping metavars or nonterminals defined with \mykw{phantom}. +\item Type generation considers each rule of the user's source grammar + except those for \verb+formula+ and \verb+terminals+ (or the + synthesized rules for the syntax of judgements or \verb+user_syntax+). +\item The subrule order is analysed to identify the top elements. For + each of those, a proof assistant type will be generated --- either a + free type (\verb+coq+: \verb+inductive+, \verb+isa+: + \verb+datatype+, \verb+hol+: \verb+Hol_datatype+), or if there is a + type hom for the proof assistant in question, a type abbreviation. + No types are generated for the non-top elements, as they will be + represented as predicates over the top free type above them. +\item For the former, each non-meta production of the rule + gives rise to a constructor. The production name (with any per-rule + prefix already applied) is used directly as the constructor name. + The (curried) constructor argument types are taken from the + types associated with the metavariables and nonterminals mentioned + in the production body. +\item Rules (within each \mykw{grammar} block, if \texttt{-merge +false}, or all rules, if \texttt{-merge true}) are topologically sorted according to the dependency order + (a free-type rule directly depends on another if one of its non-meta + productions includes a nonterminal of the other; dependencies for rules with a type-hom + for the proof assistant in question + are obtained from a crude lexing of the body of the type hom). + We then generate mutually recursive type + definitions for connected components, in an order consistent with + the dependencies. +\item For productions that involve list dot forms or list comprehension + forms, for HOL and Isabelle we produce constructors with argument + types that involve native list types. For Coq, however, we + synthesise an additional inductive type for each list-of-tuples that arises + (both for those that occur in the grammar and for others required in + the translations of inductive definitions) and include them in the + topological sort. +\end{itemize} + +\subsection{Generation of functions} +% +A small number of library functions (\verb+list_mem+, +\verb+list_minus+,...) are included in the output if they are +required. + +Several Coq list functions (\verb+map+, \verb+make+, \verb+unmake+, \verb+nth+, \verb+app+) are generated +for each synthesized list type. + +The definitions of the more interesting functions (subrule predicates, +binding auxiliaries, free variable functions, and substitutions) are +generated over the free types generated for the maximal elements of the +subrule order (generation of these functions for rules with type homs +is not supported). The definitions are by pattern-matching and +recursion. +The patterns are generated by building canonical symbolic terms from +the productions of each relevant rule. +The recursion is essentially primitive recursion: +for Coq we produce \verb+Fixpoint+s or \verb+Definition+s +(the latter is sometimes needed as the former gives an error in the case where there is no +recursion); +for Isabelle we produce \verb+primrec+s (or, experimentally, \verb+fun+s); +for HOL we use an \verb+ottDefine+ variant of the \verb+Define+ +package. +% +In general we have to deal both with the type dependency +(the topologically sorted mutually recursive types described above) +and with function dependency --- for example, for subrule predicates +and binding auxiliaries we may have multiple mutually recursive +functions over the same type. + + +For Coq the function generation over productions that involve list +types must mirror that, so we generate auxiliary functions +that recurse over those list types. + +For Isabelle the \verb+primrec+ package does not support +definitions involving several mutually recursive functions over the +same type, so for these we generate single functions calculating +tuples of results, define the intended functions as projections of +these, and generate lemmas (and simple proof scripts) characterising +them in terms of the intended definitions. +% +Further, it does not support pattern matching involving nested +constructors. We therefore generate auxiliary functions for +productions with embedded list types. Isabelle tuples are treated as +iterated pairs, so we do the same for productions with tuples of size +3 or more. +% +Isabelle also requires a function definition for each recursive type. +In the case where there are multiple uses of the same type +(e.g.~several uses of \verb+t list+ in different productions) all the +functions we wish to generate need identical auxiliaries. As yet, the +tool does not generate the identical copies required. + +If the option \verb+-isabelle_primrec+ is set to \verb+false+, then +Ott uses the \verb+fun+ package instead of the \verb+primrec+ package. +Since at the time of writing Isabelle 2008 is not capable of proving +automatically termination of all the \verb+fun+s that Ott generates, +this feature should be considered experimental. + +For HOL the standard \verb+Define+ package tries an automatic +termination proof. For productions that involve list types +our generated functions involve various list functions which prevent +those proofs working in all cases. +We therefore use an \verb+ottDefine+ variant (due to Scott Owens), + with slightly stronger support for proving termination of +definitions involving list operators. + + + +\subsubsection{Subrule predicates}\mlabel{a43}% +We generate subrule predicates to carve out the subsets of each free +proof assistant type (from the maximal elements of the subrule order) +that represent the rules of the grammar. +The non-free rules are the least subset of the rules that either +(1) occur on the left of a subrule (\verb+<::+) declaration, or +(2) have a (non-meta) production that mentions a non-free rule. +Note that these can include rules that are maximal elements of the +subrule order, e.g.~if an expression grammar included a production +involving packaged values. +The subrule predicate for a type is defined by pattern matching over +constructors of the maximal type above it --- for each non-meta +production of the maximal type it calculates a disjunction +over all the productions of the lower type that are subproductions of +it, invoking other subrule predicates as appropriate. + + +\subsubsection{Binding auxiliaries} +The binding auxiliary functions calculate the intuitive semantics of auxiliary functions defined in bindspecs of the Ott source file. Currently these are represented as proof assistant lists of metavariables or nonterminals (arguably set types should be used instead, at least in Isabelle). + + +\subsubsection{Free variables} +The free variable functions simply walk over the structure of the free proof assistant types, using any bind specifications (and binding auxiliaries) as appropriate. +% +For these, and for substitutions, we simplify the generated functions by using the dependency analysis of the syntax to exclude recursive calls where there is no dependency. + + +\subsubsection{Substitutions} +The generated substitution functions also walk over the structure of the free proof assistant types. +For each production, for each occurrence of a nonterminal \verb+nt+ within it, we first calculate the things (of whatever type is in question) binding in that \verb+nt+, i.e.~those that should be removed from the domain of any substitution pushed down into it. There are two cases: +(1) the \verb+mse'+ from any \verb+bind mse' in nt+; +%(2) the \verb+f(nt)+ which occur in the \verb+mse''+ of any \verb+bind mse'' in nt''+ +% in the production, i.e.~any auxiliary-defined things within \verb+nt+ which are used to bind elsewhere; and +(2) \verb+nt+ itself if it occurs in the \verb+mse''+ of any \verb+bind mse'' in nt''+, i.e.~ +\verb+nt+ itself if it is directly used to bind elsewhere. +List forms within bindspecs are dealt with analogously. +% + +The substitution function clause for a production is then of one of two forms: +either (1) the production comprises a single element, of the nonterminal or metavariable that we are substituting for, and this is within the rule of the nonterminal that it is being replaced by, or (2) all other cases. +For (1) the element is compared with the domain of the substitution, and replaced by the corresponding value from the range if it is found. +For (2) the substitution functions are mapped over the subelements, having first removed any bound things from the domain of the substitution. + +This is all done similarly, but with differences in detail, for single and for multiple substitutions. + + +\subsection{Generation of relations} +The semantic relations are defined +with the proof-assistant inductive relations packages +(\verb+coq+: \verb+Inductive+, +\verb+isa+: \verb+inductive+, +\verb+hol+: \verb+Hol_reln+). +% +They use the mutual recursion structure that is given by the user, +with each \verb+defns+ block giving rise to a potentially mutually +recursive definition of each \verb+defn+ inside it. +(It is debatable whether it would be preferable to do an automatic dependency analysis and topological sort, as for the syntax.) +% +Each definition rule gives rise to an implicational clause, essentially +that the premises (Ott \verb+formula+s) imply the conclusion (an Ott symbolic term of whichever judgement is being defined). +In addition: +\begin{itemize} +\item Symbolic terms are transformed in various different ways: +\begin{itemize} +\item Nodes of non-meta productions are output as applications of the appropriate proof-assistant constructor (and, for a subrule, promoted to the corresponding constructor of a maximal rule). +\item Nodes of meta productions are transformed with the user-specified homomorphism. +\item Nodes of judgement forms are represented as applications of the defined relation in Coq and HOL, and as set-membership assertions in Isabelle. +\item Lists of formulae (the \verb+formula_dots+ production) are special-cased. +\end{itemize} +\item For each nonterminal of a non-free syntax rule (as in \S\mref{a43}) that occurs, + e.g.~a usage of \verb+v'+ where \verb+v<::t+, an additional premise invoking the subrule predicate for the non-free rule is added, e.g.~\verb+is_v v'+. +\item The set of symbolic terms of the definition rule are analysed together to identify list forms with the same bounds. A single proof assistant variable is introduced for each such, with appropriate projections and list maps/foralls at the usage points. +\item For Coq, auxiliary defined relations are introduced for list forms. +\item For Coq, as the projections from list forms involve (Ott-generated) \verb+nth+ functions that return option types, for any such projection a pattern-match against \verb+Some+ is introduced as an additional premise. +\item For Coq and HOL, explicit quantifiers are introduced for all variables mentioned in the rule. +\end{itemize} + + + + +\section{Reference: Summary of homomorphisms}\mlabel{a41}% +% +Homomorphisms can appear in various positions in an Ott source +file.

The tool, +while not perfect, does make it easy to work with these +definitions, allowing one to focus on the content rather than the +proof assistant or \myLaTeX{} markup. + +For our most substantial example, the OCaml fragment, to date we have proved type preservation and +progress for the expression language, all machine-checked in HOL +except for one currently outstanding lemma (type substitution for type +variables) for +which we have a paper proof. +Alpha equivalence arises only in a lemma showing that typing is preserved by renaming the bound variables of a type scheme in the type environment. +This proof effort has +taken only around 7 man-weeks, and the preceeding definition effort +was only another few man-weeks. +Compared with our previous experiences this is remarkably lightweight: it +has been possible to develop this as an example, rather than requiring +a major research project in its own right. +Apart from \texttt{ott}, the work has been aided by HOL's powerful first-order +reasoning automation and its inductive definition package, and by the +use of the fully concrete representation. + + +We have attempted to ensure that the proof assistant definitions +generated by Ott are well-formed and what the user would intend. This +is not guaranteed, however, for several reasons: (1) There may be name +clashes between Ott-generated identifiers and proof assistant built-in +identifiers (or, in pathological cases, even among different +Ott-generated identifiers). (2) In some cases we depend on automatic +proof procedures, e.g.~for HOL definitions. These work in our test +cases, but it is hard to ensure that they will in all cases. More +importantly, (3) the generation process is complex, so it is quite +possible that there is either a bug in Ott or a mismatch between the +user expectation and what the tool actually does. Ultimately one has +to read the generated proof assistant definitions to check that they +are as intended --- but typically one would do this in any case, many +times over, in the process of proving metatheoretic results, so we do +not consider it a major issue. + + +\begin{figure} +\fbox{\begin{minipage}{\textwidth} +\input{test10.0.alltt} +\end{minipage}} +\caption{Source: \texttt{test10.0.ott}\protect\label{a4}} +\end{figure} + +\begin{figure} +\fbox{\begin{minipage}{\textwidth} +\input{test10.2.alltt} +\end{minipage}} +\caption{Source: \texttt{test10.2.ott}\protect\label{a4}} +\end{figure} + +\begin{figure} +\fbox{\begin{minipage}{\textwidth} +\input{test10.4.alltt} +\end{minipage}} +\caption{Source: \texttt{test10.4.ott}\protect\label{a4}} +\end{figure} + +\begin{figure} +\fbox{\begin{minipage}{\textwidth} +\input{test10.7.alltt} +\end{minipage}} +\caption{Source: \texttt{test10.7.ott}\protect\label{a4}} +\end{figure} + + + +\begin{figure} +\fbox{\begin{minipage}{\textwidth} +\verbatiminput{../tests/test10.ott} +\end{minipage}} +\caption{Source: \texttt{test10.ott}\protect\label{a4}} +\end{figure} + +\begin{figure} +\fbox{\begin{minipage}{\textwidth} +\testTenall +\end{minipage}} +\caption{Generated \myLaTeX: \texttt{test10.tex}\protect\label{a3}} +\end{figure} + + +\section{Example: Untyped CBV Lambda Calculus}\mlabel{a2}% +We begin with a small example, an untyped call-by-value lambda +calculus. Below we highlight the main points shown in this example +--- which uses many, but not all, of the features of Ott. We return +to the options in more detail in later sections. + +The complete Ott source file is shown in Fig.~\mref{a4}, the typeset +output in Fig.~\mref{a3}, and the generated Isabelle, Coq, and HOL files +in Figs.~\mref{a5}, \mref{a6}, and \mref{a40}. +% (the latter have been +%lightly hand-edited to remove redundant definitions so that they each fit +%on a page). + +Looking at the source file in Fig.~\mref{a4}, it begins by declaring a +metavariable form \texttt{x}, giving the Isabelle, Coq, and HOL types used +(\texttt{string}, \texttt{nat}, and \texttt{string} respectively) to represent concrete +variables, and also specifying how metavariables should be typeset. + +The following \texttt{grammar} block contains 4 grammar rules, defining +the (concrete and abstract) syntax for nonterminal roots \texttt{t}, +\texttt{v}, \texttt{terminals}. +% +Each rule has a rule name prefix (e.g.~\texttt{t\_}) and then a list +of productions. Each production, e.g. +\begin{verbatim} + \mysym{|} \ x . t :: :: Lam (+ bind x in t +) {{ com abstraction }} +\end{verbatim} +specifies a syntactic form as a list of elements, here `\verb+\+', +`\verb+x+', `\verb+.+', and `\verb+t+', each of which is either a +metavariable (the `\verb+x+'), a nonterminal (the `\verb+t+'), or a +terminal (the `\verb+\+' and `\verb+.+'). +Within productions all elements must be whitespace-separated (so that +the tool can deduce which are terminals). In the symbolic terms in +the rules below, however, whitespace is required only where necessary. + + +Metavariables and nonterminals can be formed from the specified +metavariable and nonterminal roots by appending a suffix, e.g.~the +nonterminal \verb+t'+ in the \verb+App+ and \verb+tsub+ productions. + +Terminals are not required to be declared in the \texttt{terminals} +grammar (all strings that are not metavariables or nonterminals are +regarded as terminals) but, if they are, then \myLaTeX{} pretty printing +information for them can be specified there. In this example the +`\verb+\+' is included in the \texttt{terminals} grammar and will be +\myLaTeX pretty printed as a $\lambda$, whereas the `\verb+.+' is not +included and will be pretty printed in a default form. +A few terminals have to be quoted in the grammar, as they are part of the Ott syntax, but they +do not have to be quoted at usage points. + + + +Between the \verb+::+s is an optional meta flag \verb+M+. Non-meta +productions give rise to clauses of datatype definitions in the +Isabelle/Coq/HOL output, whereas meta productions do not. + +Each production has a production name (e.g.~\verb+t_Lam+), composed of +the rule name prefix (e.g.~\verb+t_+) and the production name kernel +that follows the \verb+::+s (e.g.~\verb+Lam+). The production name is +used as a constructor name in the generated Isabelle/Coq/HOL. + +Following the production name is an optional binding specification +(e.g.~\verb-(+ bind x in t +)-), specifying which metavariables (or +nonterminals) bind in which nonterminals. This is used in the +generation of substitution and free variable functions. + +At present the generated Isabelle/Coq/HOL uses completely concrete +representations of variables in terms, without any notion of alpha +equivalence, as one can see in Fig.~\mref{a5}: +see the \verb+t+ datatype of terms and the \verb+tsubst_t+ +substitution function there. +We intend in future to generate other representations. +For a reasonably wide variety of +languages, however, one can capture the intended semantics of whole programs in +this idiom, subject only to the condition that standard library +identifiers are not shadowed within the program, as the operational +semantics does not involve reduction under binders --- so any +substitutions are of terms which (except for standard library +identifiers) are closed. This includes the ML polymorphism example of +\verb+test8.ott+.%\S\mref{a23}. +Unfortunately, for languages which require a type +environment with internal dependencies, for example F$_{<:}$, this is +no longer the case, and the POPLmark F$_{<:}$ example given in +\verb+test7.ott+ %\S\mref{a26} +has a type system which disallows all shadowing, a property that is +not preserved by reduction. + + + +Finally, there may be a number of homs, defining clauses of +homomorphisms from the grammar to strings. Certain homs have special +meanings, including: + +\begin{tabular}{ll} +\verb+com+ & defining comments used in \myLaTeX{} pretty prints of the grammar\\ +\verb+tex+ & defining how this production (and terms formed by it) are \myLaTeX{} pretty printed\\ +\verb+isa+ & (for meta productions) defining how the terms formed by +the production are translated into Isabelle\\ +\verb+coq+ & similarly for Coq\\ +\verb+hol+ & similarly for HOL\\ +\verb+ich+ & a shorthand for defining an identical triple of \verb+isa+, + \verb+coq+, and \verb+hol+ homs +\end{tabular} + +Section \mref{a41} gives a summary of all the usable homomorphisms. + +Following the \texttt{grammar} in this example is a \texttt{subrule} +declaration +\begin{verbatim} + subrules + v <:: t +\end{verbatim} +declaring that the \verb+v+ rule (of values) is a +subgrammar of the \verb+t+ rule (of terms). The tool checks that +there is in fact a subgrammar relationship, i.e.~that for each +production of the lower rule there exists a production of the higher +rule with corresponding elements (up to the subrule relation). +In the generated Isabelle/Coq/HOL for this example only one free +datatype is generated, for the \verb+t+ rule, whereas for the \verb+v+ +rule we generate an \verb+is_v+ predicate over the \verb+t+ type. Usages of +\verb+v+ nonterminals in the semantic rules have instances of this +predicate automatically inserted. + +We continue with a substitutions declaration +\begin{verbatim} + substitutions + single t x :: tsubst +\end{verbatim} +instructing the tool to generate Isabelle/Coq/HOL for a substitution +function replacing metavariables by terms. This is for single +substitutions; multiple substitution functions (taking lists of +substitutand/substitutee pairs) can also be generated. +Substitution functions are generated for all rules of the grammar for +which they might be required --- here, just over \verb+t+, with a +function named \verb+tsubst_t+. Such functions can be used in the +\verb+isa+/\verb+coq+/\verb+hol+ homomorphisms for meta syntax, e.g. as in the +production +\begin{verbatim} + | { t / x } t' :: M :: tsub {{ ich ( tsubst_t [[t]] [[x]] [[t']] ) }} +\end{verbatim} +introducing syntax for term substitution. + + +Finally, we give a collection of definitions of inductive relations. +In this example there is just one family of definitions (of +operational judgements), called \verb+Jop+; it contains just one +definition of a relation, called \verb+E+. The relation definition +also includes a grammar production specifying how elements of the +relation can be written and typeset, here +\begin{verbatim} + t1 --> t2 +\end{verbatim} +Syntax rules for each family of +judgements, and for their union, are implicitly generated. +The relation definition is given by a sequence of inference rules, +each with a horizontal line separating a number of premises from a +conclusion, for example as below. +\begin{verbatim} + t1 --> t1' + -------------- :: ctx_app_arg + v t1 --> v t1' +\end{verbatim} +The conclusion must be a symbolic term of the form of the judgement being +defined. +In simple cases (as here) the premises can be symbolic terms of the +form of any of the defined judgements. More generally (see +\S\mref{a13}) they can be symbolic terms of a user-defined +\texttt{formula} grammar. +Each rule + has a name, composed of a definition family prefix +(here empty), a definition prefix (here also empty) and a kernel +(the~\verb+ctx_app_arg+). + + + + + + + + + +\begin{figure} +\fbox{\begin{minipage}{\textwidth} +\verbatiminput{test10.thy} +%\verbatiminput{test10.hand.edited.thy} +\end{minipage}} +\caption{Generated Isabelle:\texttt{test10.thy}\protect\label{a5}} +\end{figure} + +\begin{figure} +\fbox{\begin{minipage}{\textwidth} +\verbatiminput{test10.v} +%\verbatiminput{test10.hand.edited.v} +\end{minipage}} +\caption{Generated Coq:\texttt{test10.v}\protect\label{a6}} +\end{figure} + +\begin{figure} +\fbox{\begin{minipage}{\textwidth} +\verbatiminput{test10Script.sml} +\end{minipage}} +\caption{Generated HOL:\texttt{test10Script.sml}\protect\label{a40}} +\end{figure} + + +% \section{\texttt{test1}} +% \testOneall +% +% \section{\texttt{test8}} +% \testEightall + +\clearpage + +\section{Command-line Usage}\mlabel{a32}% +The best place to get started is probably one of the test +\texttt{make} targets in the \texttt{ott} directory, e.g. +\begin{verbatim} +test10: tests/test10.ott + bin/ott \ + -isabelle out.thy -coq out.v -hol outScript.sml \ + -tex out.tex \ + -parse ":t: (\z.z z) y" \ + tests/test10.ott \ + && ($(LATEX) out; $(DVIPS) out -o) +\end{verbatim} +When \verb+make test10+ is executed, \texttt{ott}: +\begin{itemize} +\item reads the source file \verb+tests/test10.ott+ +\item prints on standard output various diagnostic information, + including ASCII versions of the grammar and + inductive definitions. + By default these are coloured (using + \verb+vt220+ control codes) with metavariables in red, nonterminals + in yellow, terminals in green, and object variables in white. + Scanning over this output quickly picks up some common errors. +\item parses the symbolic term \verb+(\z.z z) y+ using the \verb+t+ + grammar and prints the result to standard output +\item generates Isabelle definitions in the file \verb+out.thy+ +\item generates Coq definitions in the file \verb+out.v+ +\item generates HOL definitions in the file \verb+outScript.sml+ +\item generates a \myLaTeX{} document in the file \verb+out.tex+, with a + standard document preamble to make it self-contained. +\end{itemize} +That \myLaTeX{} document is then compiled and converted to postscript. + +If multiple source files are specified then they are (after parsing) +concatenated together. + + +The~\verb+%.out+ \verb+Makefile+ target runs \verb+ott+ with common +defaults on the file~\verb+%.ott+, so for example executing \verb+make tests/test10.out+ +runs \verb+ott+ on \verb+tests/test10.ott+, generating all outputs.

It assumes the reader +has read \S\mref{a2}. +\myparagraph{Grammar}\mlabel{a7}% +The tool supports arbitrary context-free grammars, extended with +special constructs for dotted list forms (c.f.~\S\mref{a21}). +% +It builds a recursive descent parser for parsing symbolic terms in +semantic rules, finding all parses up to a certain depth, and reports +an error if there are multiple parses or no parses. +% +To resolve ambiguity one can add metaproductions for parentheses (as +in Fig.~\mref{a4}), or +production-name annotations in particular symbolic terms, +e.g.~the \verb+:t_tsub:+ in the \verb+AppAbs+ rule of the POPLmark +example, \S\mref{a27}. +% +%The current parser implementation is very naive; its performance on +%larger terms can be a problem. Occasionally one must add a +%\verb+:deeper:+ annotation to a symbolic term to increase the search +%depth, as in the \verb+ax_app+ rule of Fig.~\mref{a4}. + + +\myparagraph{Lexing}\mlabel{a8}% +There are fixed lexical conventions. +In a production of the grammar specification, +the elements must be blank-separated (blanks are +\verb+( |\010|\009|\013|\012)+). + +% Nonterminals and metavariables must be idents: +% \begin{verbatim} +% ident = ([A-Z]|[a-z]|[_]) ([A-Z]|[a-z]|[0-9]|[_]|['])* +% \end{verbatim} +% Terminals must either be idents or strings that do not contain blanks +% and do not start with \verb+([A-Z]|[a-z])+. +% +% (These conventions are broadly similar to those of OCaml, except that, +% for ease of \myLaTeX{} output, we disallow accented characters in +% idents. + +(To precisely express the concrete syntax of existing full +languages would typically need more flexibility.) + +To allow the Ott tokens to appear in an object language, elements in +a grammar specification may be quoted, \verb+'thus'+. Any string +surrounded by a pair of single quotes has those quotes removed. + + + +\myparagraph{Metavariables, Nonterminals, and Suffixes}\mlabel{a9}% +Declarations of metavariable roots and rules defining nonterminal +roots can specify any number of synonyms, for example the +\verb+termvar+, \verb+x+, \verb+y+, and \verb+z+ in +\begin{verbatim} + metavar termvar , x , y , z ::= {{ isa string }} {{ coq nat }} {{ hol num }} {{ ocaml int }} +\end{verbatim} +and the \verb+t+ and \verb+u+ in +\begin{verbatim} + t , u :: '' ::= + | x :: :: Var + | \ x : T . t :: :: Lam (+ bind x in t +) + | t t' :: :: App +\end{verbatim} +The first such (here \verb+termvar+ and \verb+t+) is taken to be the +primary root, and is used to build the corresponding type name in +Isabelle/Coq/HOL/OCaml output. + +Occurrences of metavariables and nonterminals, both in productions of +the grammar specification and in symbolic terms in semantic rules, +can be formed by adding a suffix to a metavariable or nonterminal +root, for example the \verb+t'+ in the \verb+App+ rule above. + +The user can declare any number of distinguished `index' +metavariables, e.g. by: +\begin{verbatim} + indexvar index , i , j , n , m ::= {{ isa num }} {{ coq nat }} {{ hol num }} {{ ocaml int }} +\end{verbatim} +Given such a declaration, \verb+index+, \verb+i+, \verb+j+, \verb+n+ +and \verb+m+ can be used in suffixes, e.g.~in the production +\begin{verbatim} + | ( t1 , .... , tn ) :: :: Tuple +\end{verbatim} +There is a fixed ad-hoc language of suffixes, including numbers, primes, and index variables (see \S\mref{a17}). +Index metavariables cannot themselves be suffixed. + + +Metavariable declarations can include a \verb+lex+ homomorphism +specifying the syntactic form of the corresponding concrete +variables, and an \verb+isavar+ homomorphism specifying how such +strings should be translated into Isabelle. For example, one might write +\begin{verbatim} + metavar typevar , X ::= {{ isa string }} {{ lex Alphanum }} + metavar termvar , x ::= {{ isa string }} {{ lex alphanum }} +\end{verbatim} +Similarly, one can specify how concrete variables should be \myLaTeX'd, e.g.~with +the homomorphisms \verb+{{ texvar \mathrm{[[typevar]]} }}+ and \verb+{{ isavar ''[[termvar]]'' }}+. + +\textbf{At present \texttt{lex} homomorphism must have body either} + \texttt{Alphanum} (\verb+[A-Z]([A-Z]|[a-z]|[0-9]|'|_)*+), + \texttt{alphanum} (\verb+([A-Z]|[a-z])([A-Z]|[a-z]|[0-9]|'|_)*+), + \texttt{alphanum0} (\verb+[a-z]([A-Z]|[a-z]|[0-9]|'|_)*+), or + \texttt{numeral} (\verb+[0-9][0-9]*+); \textbf{more general regexps are not supported.} + +One can likewise specify how metavariables themselves should be +\myLaTeX'd, e.g.~with a homomorphism +\verb+{{ tex \mathit{[[typevar]]} }}+. + +For Coq output, one can specify \verb+{{ coq-equality+ \textit{proof-script} \verb+}}+ +to build a decidable equality over the Coq representation type using +the proof \textit{proof-script}. If the script is omitted it defaults +to +\begin{verbatim} +Proof. + decide equality; auto with ott_coq_equality arith. +Defined. +\end{verbatim} +where the \verb+ott_coq_equality+ database contains the decidable +equalities of the representation types defined in the source. + +\myparagraph{Grammar Rule Homomorphisms}\mlabel{a11}% +% +Grammar rules can be annotated with various homomorphisms. + +First, the individual nonterminal roots can have \verb+tex+ +homomorphisms specifying how they should be typeset, e.g.~ +\begin{verbatim} +G {{ tex \Gamma }} , D {{ tex \Delta }} :: 'G_' ::= {{ com type environment }} + | empty :: :: empty + | G , x : T :: :: term +\end{verbatim} +permitting the user to write \verb+G'+, \verb+D12+ etc.~in symbolic +terms, to be typeset at $\Gamma'$, $\Delta_{12}$, etc. + +Second, the rule can include a \verb+tex+ hom specifying how all the + nonterminal roots should be typeset, e.g. +\begin{verbatim} + type , t , s :: Typ_ ::= {{ tex \mathsf{[[type]]} }} + | unit :: :: unit + | type * type' :: :: pair + | type -> type' :: :: fun +\end{verbatim} +Here that \verb+tex+ hom overrides the default typesetting with +\verb+\mathsf+. + +Third, the rule can include a \verb+com+ hom giving a comment to +include in typeset versions of the grammar itself, e.g.~the +\verb+{{ com type environment }}+ above. + +Fourth, the rule can include a \verb+coq equality+ hom, instructing +the Coq code generator to derive a decidable equality for the Coq +representation type. For example, the ML polymorphism Ott source of +\texttt{test8.ott} includes the following. +\begin{verbatim} + typvar :: TV_ ::= {{ coq-equality decide equality. apply eq_value_name_t. }} + | ' ident :: :: ident +\end{verbatim} + +Fifth, and most fundamentally, the rule can include \verb+isa+, \verb+coq+, +\verb+hol+, or \verb+ocaml+ homs specifying a proof-assistant (or OCaml) type, e.g. in the +following rule for substitutions. +\begin{verbatim} + s {{ tex \sigma }} :: 'S_' ::= {{ com multiple subst }} {{ isa (termvar*t) list }} + | [ x |-> t ] :: :: singleton {{ isa [ ([[x]],[[t]]) ] }} + | s1 , .. , sn :: :: list {{ isa List.concat s_list }} +\end{verbatim} +Here the \verb+{{ isa (termvar*t) list }}+ hom specifies that in +Isabelle output this type be represented as an Isabelle +\verb+(termvar*t) list+ instead of the (default) free grammar. + + + +\myparagraph{Production Homomorphisms}\mlabel{a12}% +Each production may also have \verb+coq+ and \verb+isa+ homomorphisms, +specifying how symbolic terms should be translated into Isabelle/Coq/HOL/OCaml +expressions, e.g.~as in the last example of the previous +section. This overrides the default translation into terms of a free +grammar. + +Productions may also have \verb+tex+ homs, overriding the default +\myLaTeX{} typesetting, e.g.~as in this example of +a type abstraction production from \texttt{test7.ott}. +\begin{verbatim} + | \ X <: T . t :: :: TLam (+ bind X in t +) + {{ com type abstraction }} + {{ tex \Lambda [[X]] [[<:]] [[T]]. \, [[t]] }} +\end{verbatim} +They may also have a comment, e.g.~the \verb+{{ com type abstraction }}+, to +appear in typeset versions of the grammar itself. + +All these homomorphisms can refer to the metavariables and +nonterminals that occur in the production, e.g.~the \verb+[[X]]+, +\verb+[[T]]+, and \verb+[[t]]+ in the \verb+tex+ hom above, +interleaved with arbitrary strings and with typeset elements of the +\verb+terminals+ grammar, e.g.~the \verb+[[<:]]+. + +Homomorphisms are applied recursively down the structure of symbolic +terms.

It +turns any sequence of \verb+[+ (resp. of \verb+]+) of +length $n+1$ for $n>2$ into a literal sequence of length $n$. + +The following two subsections show a source file (\verb+test7tt.mng+) that uses terms of the F$_{<:}$ +definition of \texttt{test7.ott}, and the result of filtering it. + +Similar filtering can be performed on Coq, Isabelle, HOL, and OCaml files. + +\subsubsection{F$_{<:}$ Extracts --- Source File}\mlabel{a29}% +\verbatiminput{../tests/test7tt.mng} + +\subsubsection{F$_{<:}$ Extracts --- The Filtered Output}\mlabel{a30}% +\input{test7tt.tex} + + +\myparagraph{Isabelle Syntax Support}\mlabel{a39}% +The tool has (limited) facilities to allow the Isabelle mixfix syntax support +and xsymbol to be used. The example \verb+test10_isasyn.ott+ shows +this in use. +% + +Non-meta productions can be annotated with +\verb+isasyn+ and/or \verb+isaprec+ homomorphisms. +For example, \verb+test10_isasyn.ott+ contains the production +\par\noindent{\small +\begin{verbatim} + | t t' :: :: App {{ isasyn [[t]]\[[t']] }} {{ isaprec 50 }} +\end{verbatim} +} +The two homs are used to output the Isabelle syntax annotation in the +\verb+t_App+ clause of the datatype definition below. +\par\noindent{\small +\begin{verbatim} +t = + t_Var "termvar" + | t_Lam "termvar" "t" ("\ _ . _" 60) + | t_App "t" "t" ("_\_" 50) +\end{verbatim} +} +Definitions can be annotated with +\verb+isasyn+ and/or \verb+isaprec+ homomorphisms similarly, e.g.~as below. +\par\noindent{\small +\begin{verbatim} + defn + t1 --> t2 :: :: reduce :: '' {{ isasyn [[t1]] ---> [[t2]] }} by +\end{verbatim} +} +This generates \verb+syntax+ and \verb+translations+ blocks as below. +\par\noindent{\small +\begin{verbatim} +consts + reduce :: "(t*t) set" + +syntax + "_reduce" :: "t => t => bool" ("_ ---> _" 50) + +translations + "(t17 ---> t27)" \ " ( t17 , t27 ) : reduce" +\end{verbatim} +} +Symbolic terms in definitions are printed using any production or +definition syntax. This (especially with xsymbol turned on) makes the +current goal state during Isabelle proof development much more +readable. + + + +Further, there is a command line option \verb+-isa_syntax true+. If +this is set then the tool generates Isabelle syntax annotations from +the source syntax. For example, the source file production for the +\verb+t_Lam+ clause is +\par\noindent{\small +\begin{verbatim} + | \ x . t :: :: Lam {{ isaprec 60 }} +\end{verbatim} +} +and the \verb+terminals+ grammar contains a mapping from \verb+\+ to \verb+\+: +\par\noindent{\small +\begin{verbatim} + terminals :: 'terminals_' ::= + | \ :: :: lambda {{ tex \lambda }} {{ isa \ }} +\end{verbatim} +} +This is used (just as for \myLaTeX{} homs) to generate the \verb+("\ _ . _" 60)+ +in the datatype definition above. + + +Limitations: +(1) the full range of Isabelle precedence and associativity +specifications are not supported; +(2) the automatically generated syntax annotations are somewhat crude, +especially w.r.t.~spacing and parenthesisation; +(3) syntax annotation on meta productions is not propertly supported; +and +(4) it would be desirable to have more fine-grain control of whether +to automatically generate annotations: per-production, per-rule, and +per-file. + + +%For example, the \verb+out.thy+ produced by +%\verb+make test10_isasyn+ (which includes this option), the annotation +%on + + +\myparagraph{Code Generation}\mlabel{a22}% +The Isabelle/Coq/HOL code generation facilities can be used to +generate (variously) OCaml and SML code from the definitions, if +they are suitably constrained. + +For example, the \verb+test10st_codegen.thy+ file uses Isabelle +code generation to produce SML code to calculate the possible +reductions of terms in the \verb+test10st.ott+ simply typed lambda +calculus. + +\verbatiminput{../tests/test10st_codegen.thy} + + + +\section{Example: Simply Typed Lambda Calculus}\mlabel{a34}% +This example extends the untyped lambda calculus of \S\mref{a2} with a +simple type system. We include Isabelle proof script for the +standard metatheoretic results, type preservation and progress. +% +In order to define a reasonable system using the concrete representation of +variables and binding, +the type system here is slightly unusual. It allows repeated +types for identifiers in type environments, with the rightmost being +the significant one. Type preservation is proved only for closed +terms, though it should be straightforward to weaken that to allow +terms that do not shadow identifiers in a standard library --- a +sufficient condition to prevent capture, as all substitutions +performed during reduction are of values that are closed except for standard +library identifiers. + +The definition presented here represents type environments using proof-assistant list types. For Isabelle we have also tried a variant using +a functional representation, that gave rise to somewhat simpler proof scripts. + +\subsection{Ott source}\mlabel{a35}% +{\small +\verbatiminput{../tests/test10st.ott} +} +\subsection{Generated \myLaTeX}\mlabel{a36}% +\testTenstall + +\subsection{Isabelle Proof Script for Metatheory (with Tom Ridge)}\mlabel{a37}% +{\small +\verbatiminput{../tests/test10st_metatheory_autoed.thy} +} + + + +\section{Example: ML Polymorphism (in an OCaml syntax fragment)}\mlabel{a23}% +\subsection{Ott Source}\mlabel{a24}% +{\small +\verbatiminput{../tests/test8.ott} +} +\subsection{Generated \myLaTeX}\mlabel{a25}% +\testEightall + +\section{Example: POPLmark F$_{<:}$ with Records}\mlabel{a26}% +Note that, as mentioned in \S\mref{a2}, the concrete variable +representation is not satisfactory for this example. +\subsection{Ott Source}\mlabel{a27}% +{\small +\verbatiminput{../src/tmp_test7_clean.ott} +} +\subsection{Generated \myLaTeX }\mlabel{a28}% +\testSevenall + +\end{document} + + + +\end{document} + + +%%% Local Variables: +%%% LaTeX-label-sequence-N: 69 +%%% LaTeX-label-prefix: "a" +%%% End: diff --git a/vendors/ott/emacs/ott-mode.el b/vendors/ott/emacs/ott-mode.el new file mode 100644 index 000000000000..95553692fdeb --- /dev/null +++ b/vendors/ott/emacs/ott-mode.el @@ -0,0 +1,32 @@ +(define-generic-mode 'ott-mode + '("%") + '("metavar" "indexvar" "grammar" "embed" "subrules" "contextrules" "substitutions" "single" "multiple" "freevars" "defns" "defn" "by" "homs" "funs" "fun" "parsing" "begincoqsection" "endcoqsection" "coqvariable" "left" "right" "terminals" "formula" "judgement") + '( +; ("\\[\\[.+\\]\\]" .

It is written in Ott~\cite{ott}, which generates +\LaTeX, HOL, Coq, and Isabelle/HOL definitions, and it comprises a small-step +operational semantics and a syntactic, non-algorithmic type system. A type +soundness theorem has been proved and mechanized in HOL-4. To ensure that the +operational semantics accurately models Objective Caml, an executable version +of the semantics has been created (and proved equivalent in HOL to the +original, relational version) and tested on a number of small test cases. + +We take a straightforward approach, formalizing the syntax of \OCL{} as a +collection of inductive datatypes, and the \OCL{} type system and operational +semantics as a collection of inductive relations and recursive functions +directly over the source syntax. We hypothesize that this clear connection +between the source language and its semantics will facilitate verification +about \OCL{} programs, in addition to the present verification of type +soundness. \OCL{} covers a large part of Objective Caml, but excludes the +language's module and object systems. It includes: +\begin{itemize} +\item +definitions +\begin{itemize} +\item +variant data types (e.g., \verb+type t = I of int | C of char+), +\item +record types (e.g., \verb+type t = {f : int; g : bool}+), +\item +parametric type constructors (e.g., \verb+type 'a t = C of 'a+), +\item +type abbreviations (e.g., \verb+type 'a t = 'a * int+), +\item +mutually recursive combinations of the above (excepting abbreviations), +\item +exceptions, and values; +\end{itemize} +\item +expressions for type annotations, sequencing, and primitive values (functions, lists, tuples, and records); +\item +\verb+with+ (record update), \verb+if+, \verb+while+, \verb+for+, \verb+assert+, \verb+try+, and \verb+raise+ expressions; +\item +let-based polymorphism with an SML-style value restriction; +\item +mutually-recursive function definitions via \verb+let rec+; +\item +pattern matching, with nested patterns, \verb+as+ patterns, and ``or'' (\verb+|+)patterns; +\item +mutable references with \verb+ref+, \verb+!+, and \verb+:=+; +\item +polymorphic equality (the Objective Caml \verb+=+ operator); +\item +31-bit word semantics for \texttt{int}s (using an existing HOL library); and +\item +IEEE-754 semantics for \texttt{float}s (using an existing HOL library). +\end{itemize} + +Most of the proof effort is a straightforward application of HOL's tactic-based proof mechanisms. The entire proof is around 11000 lines of tactic scripts. +The poster will present the \OCL{} semantics and also lessons from the verification process. +\bibliographystyle{splncs} +\vspace{-30pt}

The Pervasives module is +%special in two ways: +% +% - It is automatically linked with the user-s object code files by the ocamlc +% command (chapter 8). +% +% - It is automatically --opened-- when a compilation starts, or when the +% toplevel system is launched. Hence, it is possible to use unqualified +% identifiers to refer to the functions provided by the Pervasives module, +% without adding a open Pervasives directive. +% +% +%Conventions +%*=*=*=*=*=* +% +% +% The declarations of the built-in types and the components of module +%Pervasives are printed one by one in typewriter font, followed by a short +%comment.

Mutable +% structures (e.g. references and arrays) are equal if and only +% if their current contents are structurally equal, even if the +% two mutable objects are not the same physical object. Equality +% between functional values raises Invalid_argument. Equality +% between cyclic data structures does not terminate. +% +%<< + val (<>) : 'a -> 'a -> bool +%>> +% +% Negation of Pervasives.(=)[19.2]. +% +%<< + val (<) : 'a -> 'a -> bool +%>> +% +% See Pervasives.(>=)[19.2]. +% +%<< + val (>) : 'a -> 'a -> bool +%>> +% +% See Pervasives.(>=)[19.2]. +% +%<< + val (<=) : 'a -> 'a -> bool +%>> +% +% See Pervasives.(>=)[19.2]. +% +%<< + val (>=) : 'a -> 'a -> bool +%>> +% +% Structural ordering functions. These functions coincide with +% the usual orderings over integers, characters, strings and +% floating-point numbers, and extend them to a total ordering +% over all types. The ordering is compatible with (=). As in the +% case of (=), mutable structures are compared by contents. +% Comparison between functional values raises Invalid_argument. +% Comparison between cyclic structures does not terminate. +% +%<< + val compare : 'a -> 'a -> int +%>> +% +% compare x y returns 0 if x is equal to y, a negative integer +% if x is less than y, and a positive integer if x is greater +% than y. The ordering implemented by compare is compatible with +% the comparison predicates =, < and > defined above, with one +% difference on the treatment of the float value +% Pervasives.nan[19.2]. Namely, the comparison predicates treat +% nan as different from any other float value, including itself; +% while compare treats nan as equal to itself and less than any +% other float value. This treatment of nan ensures that compare +% defines a total ordering relation. +% compare applied to functional values may raise Invalid_argument. +% compare applied to cyclic structures may not terminate. +% The compare function can be used as the comparison function +% required by the Set.Make[20.28] and Map.Make[20.18] functors, as +% well as the List.sort[20.17] and Array.sort[20.2] functions. +% +%<< +% val min : 'a -> 'a -> 'a +%>> +% +% Return the smaller of the two arguments. +% +%<< +% val max : 'a -> 'a -> 'a +%>> +% +% Return the greater of the two arguments. +% +%<< +% val (==) : 'a -> 'a -> bool +%>> +% +% e1 == e2 tests for physical equality of e1 and e2. On integers +% and characters, physical equality is identical to structural +% equality. On mutable structures, e1 == e2 is true if and only if +% physical modification of e1 also affects e2. On non-mutable +% structures, the behavior of (==) is implementation-dependent; +% however, it is guaranteed that e1 == e2 implies compare e1 e2 = +% 0. +% +%<< +% val (!=) : 'a -> 'a -> bool +%>> +% +% Negation of Pervasives.(==)[19.2]. +% +% +Boolean operations +================== +% +%<< + val not : bool -> bool +%>> +% +% The boolean negation. +% +%<< + val (&&) : bool -> bool -> bool +%>> +% +% The boolean -'and--.

All operations +are taken modulo 2^31 (or 2^63). They do not fail on overflow. +%<< +% val (~-) : int -> int +%>> +% +% Unary negation. You can also write -e instead of ~-e. +% +%<< +% val succ : int -> int +%>> +% +% succ x is x+1. +% +%<< +% val pred : int -> int +%>> +% +% pred x is x-1. +% +%<< + val (+) : int -> int -> int +%>> +% +% Integer addition. +% +%<< + val (-) : int -> int -> int +%>> +% +% Integer subtraction. +% +%<< + val (*) : int -> int -> int +%>> +% +% Integer multiplication. +% +%<< + val (/) : int -> int -> int +%>> +% +% Integer division. Raise Division_by_zero if the second +% argument is 0. Integer division rounds the real quotient of its +% arguments towards zero. More precisely, if x >= 0 and y > 0, x +% / y is the greatest integer less than or equal to the real +% quotient of x by y. Moreover, (-x) / y = x / (-y) = -(x / y). +% +%<< +% val mod : int -> int -> int +%>> +% +% Integer remainder. If y is not zero, the result of x mod y +% satisfies the following properties: x = (x / y) * y + x mod y +% and abs(x mod y) <= abs(y)-1. If y = 0, x mod y raises +% Division_by_zero. Notice that x mod y is negative if and only +% if x < 0. +% +%<< +% val abs : int -> int +%>> +% +% Return the absolute value of the argument. +% +%<< + val max_int : int +%>> +% +% The greatest representable integer. +% +%<< + val min_int : int +%>> +% +% The smallest representable integer. +% +% +%Bitwise operations +%------------------ +% +%<< +% val land : int -> int -> int +%>> +% +% Bitwise logical and. +% +%<< +% val lor : int -> int -> int +%>> +% +% Bitwise logical or. +% +%<< +% val lxor : int -> int -> int +%>> +% +% Bitwise logical exclusive or. +% +%<< +% val lnot : int -> int +%>> +% +% Bitwise logical negation. +% +%<< +% val lsl : int -> int -> int +%>> +% +% n lsl m shifts n to the left by m bits.

This is an arithmetic +% shift: the sign bit of n is replicated. The result is +% unspecified if m < 0 or m >= bitsize. +% +% +%Floating-point arithmetic +%========================= +% +% Caml-s floating-point numbers follow the IEEE 754 standard, using double +%precision (64 bits) numbers. Floating-point operations never raise an +%exception on overflow, underflow, division by zero, etc. Instead, special IEEE +%numbers are returned as appropriate, such as infinity for 1.0 /. 0.0, +%neg_infinity for -1.0 /. 0.0, and nan (--not a number--) for 0.0 /. 0.0. These +%special numbers then propagate through floating-point computations as +%expected: for instance, 1.0 /. infinity is 0.0, and any operation with nan as +% argument returns nan as result. +%<< +% val (~-.) : float -> float +%>> +% +% Unary negation.

Return the string of +% all characters read, without the newline character at the end. +% +%<< +% val read_int : unit -> int +%>> +% +% Flush standard output, then read one line from standard input +% and convert it to an integer. Raise Failure "int_of_string" if +% the line read is not a valid representation of an integer. +% +%<< +% val read_float : unit -> float +%>> +% +% Flush standard output, then read one line from standard input +% and convert it to a floating-point number. The result is +% unspecified if the line read is not a valid representation of a +% floating-point number. +% +% +%General output functions +%------------------------ +% +%<< +% type open_flag = +% | Open_rdonly +%>> +% +% open for reading. +% +%<< +% | Open_wronly +%>> +% +% open for writing. +% +%<< +% | Open_append +%>> +% +% open for appending: always write at end of file. +% +%<< +% | Open_creat +%>> +% +% create the file if it does not exist. +% +%<< +% | Open_trunc +%>> +% +% empty the file if it already exists. +% +%<< +% | Open_excl +%>> +% +% fail if Open_creat and the file already exists. +% +%<< +% | Open_binary +%>> +% +% open in binary mode (no conversion). +% +%<< +% | Open_text +%>> +% +% open in text mode (may perform conversions). +% +%<< +% | Open_nonblock +%>> +% +% open in non'blocking mode. +% +% Opening modes for Pervasives.open_out_gen[19.2] and +% Pervasives.open_in_gen[19.2]. +% +%<< +% val open_out : string -> out_channel +%>> +% +% Open the named file for writing, and return a new output +% channel on that file, positionned at the beginning of the file. +% The file is truncated to zero length if it already exists. It +% is created if it does not already exists. Raise Sys_error if +% the file could not be opened. +% +%<< +% val open_out_bin : string -> out_channel +%>> +% +% Same as Pervasives.open_out[19.2], but the file is opened in +% binary mode, so that no translation takes place during writes. +% On operating systems that do not distinguish between text mode +% and binary mode, this function behaves like +% Pervasives.open_out[19.2]. +% +%<< +% val open_out_gen : open_flag list -> int -> string -> out_channel +%>> +% +% Open the named file for writing, as above. The extra argument +% mode specify the opening mode. The extra argument perm +% specifies the file permissions, in case the file must be +% created. Pervasives.open_out[19.2] and +% Pervasives.open_out_bin[19.2] are special cases of this +% function. +% +%<< +% val flush : out_channel -> unit +%>> +% +% Flush the buffer associated with the given output channel, +% performing all pending writes on that channel. Interactive +% programs must be careful about flushing standard output and +% standard error at the right time. +% +%<< +% val flush_all : unit -> unit +%>> +% +% Flush all open output channels; ignore errors. +% +%<< +% val output_char : out_channel -> char -> unit +%>> +% +% Write the character on the given output channel. +% +%<< +% val output_string : out_channel -> string -> unit +%>> +% +% Write the string on the given output channel. +% +%<< +% val output : out_channel -> string -> int -> int -> unit +%>> +% +% output oc buf pos len writes len characters from string buf, +% starting at offset pos, to the given output channel oc.

The given integer is taken +% modulo 256. +% +%<< +% val output_binary_int : out_channel -> int -> unit +%>> +% +% Write one integer in binary format (4 bytes, big-endian) on +% the given output channel. The given integer is taken modulo +% 2^32. The only reliable way to read it back is through the +% Pervasives.input_binary_int[19.2] function. The format is +% compatible across all machines for a given version of Objective +% Caml. +% +%<< +% val output_value : out_channel -> 'a -> unit +%>> +% +% Write the representation of a structured value of any type to +% a channel. Circularities and sharing inside the value are +% detected and preserved. The object can be read back, by the +% function Pervasives.input_value[19.2]. See the description of +% module Marshal[20.19] for more information. +% Pervasives.output_value[19.2] is equivalent to +% Marshal.to_channel[20.19] with an empty list of flags. +% +%<< +% val seek_out : out_channel -> int -> unit +%>> +% +% seek_out chan pos sets the current writing position to pos for +% channel chan. This works only for regular files. On files of +% other kinds (such as terminals, pipes and sockets), the +% behavior is unspecified. +% +%<< +% val pos_out : out_channel -> int +%>> +% +% Return the current writing position for the given channel. Does +% not work on channels opened with the Open_append flag (returns +% unspecified results). +% +%<< +% val out_channel_length : out_channel -> int +%>> +% +% Return the size (number of characters) of the regular file on +% which the given channel is opened. If the channel is opened on +% a file that is not a regular file, the result is meaningless. +% +%<< +% val close_out : out_channel -> unit +%>> +% +% Close the given channel, flushing all buffered write +% operations. Output functions raise a Sys_error exception when +% they are applied to a closed output channel, except close_out +% and flush, which do nothing when applied to an already closed +% channel. Note that close_out may raise Sys_error if the +% operating system signals an error when flushing or closing. +% +%<< +% val close_out_noerr : out_channel -> unit +%>> +% +% Same as close_out, but ignore all errors. +% +%<< +% val set_binary_mode_out : out_channel -> bool -> unit +%>> +% +% set_binary_mode_out oc true sets the channel oc to binary +% mode: no translations take place during output. +% set_binary_mode_out oc false sets the channel oc to text mode: +% depending on the operating system, some translations may take +% place during output. For instance, under Windows, end-of-lines +% will be translated from \n to \r\n. This function has no effect +% under operating systems that do not distinguish between text +% mode and binary mode. +% +% +%General input functions +%----------------------- +% +%<< +% val open_in : string -> in_channel +%>> +% +% Open the named file for reading, and return a new input channel +% on that file, positionned at the beginning of the file. Raise +% Sys_error if the file could not be opened. +% +%<< +% val open_in_bin : string -> in_channel +%>> +% +% Same as Pervasives.open_in[19.2], but the file is opened in +% binary mode, so that no translation takes place during reads. +% On operating systems that do not distinguish between text mode +% and binary mode, this function behaves like +% Pervasives.open_in[19.2]. +% +%<< +% val open_in_gen : open_flag list -> int -> string -> in_channel +%>> +% +% Open the named file for reading, as above. The extra arguments +% mode and perm specify the opening mode and file permissions. +% Pervasives.open_in[19.2] and Pervasives.open_in_bin[19.2] are +% special cases of this function. +% +%<< +% val input_char : in_channel -> char +%>> +% +% Read one character from the given input channel. Raise +% End_of_file if there are no more characters to read. +% +%<< +% val input_line : in_channel -> string +%>> +% +% Read characters from the given input channel, until a newline +% character is encountered. Return the string of all characters +% read, without the newline character at the end. Raise +% End_of_file if the end of the file is reached at the beginning +% of line. +% +%<< +% val input : in_channel -> string -> int -> int -> int +%>> +% +% input ic buf pos len reads up to len characters from the given +% channel ic, storing them in string buf, starting at character +% number pos. It returns the actual number of characters read, +% between 0 and len (inclusive). A return value of 0 means that +% the end of file was reached. A return value between 0 and len +% exclusive means that not all requested len characters were +% read, either because no more characters were available at that +% time, or because the implementation found it convenient to do a +% partial read; input must be called again to read the remaining +% characters, if desired. (See also Pervasives.really_input[19.2] +% for reading exactly len characters.) Exception +% Invalid_argument "input" is raised if pos and len do not +% designate a valid substring of buf. +% +%<< +% val really_input : in_channel -> string -> int -> int -> unit +%>> +% +% really_input ic buf pos len reads len characters from channel +% ic, storing them in string buf, starting at character number +% pos. Raise End_of_file if the end of file is reached before len +% characters have been read. Raise Invalid_argument +% "really_input" if pos and len do not designate a valid +% substring of buf. +% +%<< +% val input_byte : in_channel -> int +%>> +% +% Same as Pervasives.input_char[19.2], but return the 8'bit +% integer representing the character. Raise End_of_file if an +% end of file was reached. +% +%<< +% val input_binary_int : in_channel -> int +%>> +% +% Read an integer encoded in binary format (4 bytes, big-endian) +% from the given input channel. See +% Pervasives.output_binary_int[19.2]. Raise End_of_file if an end +% of file was reached while reading the integer. +% +%<< +% val input_value : in_channel -> 'a +%>> +% +% Read the representation of a structured value, as produced by +% Pervasives.output_value[19.2], and return the corresponding +% value. This function is identical to +% Marshal.from_channel[20.19]; see the description of module +% Marshal[20.19] for more information, in particular concerning +% the lack of type safety. +% +%<< +% val seek_in : in_channel -> int -> unit +%>> +% +% seek_in chan pos sets the current reading position to pos for +% channel chan. This works only for regular files. On files of +% other kinds, the behavior is unspecified. +% +%<< +% val pos_in : in_channel -> int +%>> +% +% Return the current reading position for the given channel. +% +%<< +% val in_channel_length : in_channel -> int +%>> +% +% Return the size (number of characters) of the regular file on +% which the given channel is opened. If the channel is opened on +% a file that is not a regular file, the result is meaningless. +% The returned size does not take into account the end-of-line +% translations that can be performed when reading from a channel +% opened in text mode. +% +%<< +% val close_in : in_channel -> unit +%>> +% +% Close the given channel. Input functions raise a Sys_error +% exception when they are applied to a closed input channel, +% except close_in, which does nothing when applied to an already +% closed channel. Note that close_in may raise Sys_error if the +% operating system signals an error. +% +%<< +% val close_in_noerr : in_channel -> unit +%>> +% +% Same as close_in, but ignore all errors. +% +%<< +% val set_binary_mode_in : in_channel -> bool -> unit +%>> +% +% set_binary_mode_in ic true sets the channel ic to binary mode: +% no translations take place during input. set_binary_mode_out ic +% false sets the channel ic to text mode: depending on the +% operating system, some translations may take place during +% input. For instance, under Windows, end-of-lines will be +% translated from \r\n to \n. This function has no effect under +% operating systems that do not distinguish between text mode and +% binary mode. +% +% +%Operations on large files +%------------------------- +% +%<< +% module LargeFile : >> +% +% sig +% +% +% << +% val seek_out : Pervasives.out_channel -> int64 -> unit +% >> +% +% << +% val pos_out : Pervasives.out_channel -> int64 +% >> +% +% << +% val out_channel_length : Pervasives.out_channel -> int64 +% >> +% +% << +% val seek_in : Pervasives.in_channel -> int64 -> unit +% >> +% +% << +% val pos_in : Pervasives.in_channel -> int64 +% >> +% +% << +% val in_channel_length : Pervasives.in_channel -> int64 +% >> +% +% - end +% +% Operations on large files. This sub-module provides 64'bit +% variants of the channel functions that manipulate file +% positions and file sizes. By representing positions and sizes +% by 64'bit integers (type int64) instead of regular integers +% (type int), these alternate functions allow operating on files +% whose sizes are greater than max_int. +% +% +References +========== +% +%<< + type 'a ref +% type 'a ref = { +% mutable contents : 'a ; +% } +%>> +% +% The type of references (mutable indirection cells) containing +% a value of type 'a. +% +%<< + val ref : 'a -> 'a ref +%>> +% +% Return a fresh reference containing the given value. +% +%<< + val (!) : 'a ref -> 'a +%>> +% +% !r returns the current contents of reference r.

All open output channels +% are flushed with flush_all. An implicit exit 0 is performed +% each time a program terminates normally. An implicit exit 2 is +% performed if the program terminates early because of an +% uncaught exception. +% +%<< +% val at_exit : (unit -> unit) -> unit +%>> +% +% Register the given function to be called at program +% termination time. The functions registered with at_exit will be +% called when the program executes Pervasives.exit[19.2], or +% terminates, either normally or because of an uncaught exception. +% The functions are called in --last in, first out-- order: the +% function most recently added with at_exit is called first. +% +% +% +% +% +%Chapter 20 The standard library +%********************************** +% +% This chapter describes the functions provided by the Objective Caml standard +%library. The modules from the standard library are automatically linked with +%the user-s object code files by the ocamlc command. Hence, these modules can be +%used in standalone programs without having to add any .cmo file on the command +%line for the linking phase. Similarly, in interactive use, these globals can be +%used in toplevel phrases without having to load any .cmo file in memory. +% Unlike the Pervasive module from the core library, the modules from the +%standard library are not automatically --opened-- when a compilation starts, or +%when the toplevel system is launched. Hence it is necessary to use qualified +%identifiers to refer to the functions provided by these modules, or to add open +%directives. +% +% +%Conventions +%*=*=*=*=*=* +% +% +% For easy reference, the modules are listed below in alphabetical order of +%module names. For each module, the declarations from its signature are printed +%one by one in typewriter font, followed by a short comment. All modules and the +%identifiers they export are indexed at the end of this report. +% +% +% +%20.1 Module Arg : Parsing of command line arguments. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* +% +% +% This module provides a general mechanism for extracting options and +%arguments from the command line to the program. +% Syntax of command lines: A keyword is a character string starting with a -. +%An option is a keyword alone or followed by an argument. The types of keywords +%are: Unit, Bool, Set, Clear, String, Set_string, Int, Set_int, Float, +%Set_float, Tuple, Symbol, and Rest. Unit, Set and Clear keywords take no +%argument. A Rest keyword takes the remaining of the command line as arguments. +% Every other keyword takes the following word on the command line as argument. +% Arguments not preceded by a keyword are called anonymous arguments. +% Examples (cmd is assumed to be the command name): +% +% - cmd -flag (a unit option) +% - cmd -int 1 (an int option with argument 1) +% - cmd -string foobar (a string option with argument "foobar") +% - cmd -float 12.34 (a float option with argument 12.34) +% - cmd a b c (three anonymous arguments: "a", "b", and "c") +% - cmd a b -- c d (two anonymous arguments and a rest option with two +% arguments) +% +% 0.5cm +%<< +% type spec = +% | Unit of (unit -> unit) +%>> +% +% Call the function with unit argument +% +%<< +% | Bool of (bool -> unit) +%>> +% +% Call the function with a bool argument +% +%<< +% | Set of bool Pervasives.ref +%>> +% +% Set the reference to true +% +%<< +% | Clear of bool Pervasives.ref +%>> +% +% Set the reference to false +% +%<< +% | String of (string -> unit) +%>> +% +% Call the function with a string argument +% +%<< +% | Set_string of string Pervasives.ref +%>> +% +% Set the reference to the string argument +% +%<< +% | Int of (int -> unit) +%>> +% +% Call the function with an int argument +% +%<< +% | Set_int of int Pervasives.ref +%>> +% +% Set the reference to the int argument +% +%<< +% | Float of (float -> unit) +%>> +% +% Call the function with a float argument +% +%<< +% | Set_float of float Pervasives.ref +%>> +% +% Set the reference to the float argument +% +%<< +% | Tuple of spec list +%>> +% +% Take several arguments according to the spec list +% +%<< +% | Symbol of string list * (string -> unit) +%>> +% +% Take one of the symbols as argument and call the function with +% the symbol +% +%<< +% | Rest of (string -> unit) +%>> +% +% Stop interpreting keywords and call the function with each +% remaining argument +% +% The concrete type describing the behavior associated with a +% keyword. +% +%<< +% type key = string +%>> +% +%<< +% type doc = string +%>> +% +%<< +% type usage_msg = string +%>> +% +%<< +% type anon_fun = string -> unit +%>> +% +%<< +% val parse : (key * spec * doc) list -> anon_fun -> usage_msg -> unit +%>> +% +% Arg.parse speclist anon_fun usage_msg parses the command line. +% speclist is a list of triples (key, spec, doc). key is the +% option keyword, it must start with a --- character. spec gives +% the option type and the function to call when this option is +% found on the command line. doc is a one-line description of +% this option. anon_fun is called on anonymous arguments. The +% functions in spec and anon_fun are called in the same order as +% their arguments appear on the command line. +% If an error occurs, Arg.parse exits the program, after printing +% an error message as follows: +% +% - The reason for the error: unknown option, invalid or missing +% argument, etc. +% - usage_msg +% - The list of options, each followed by the corresponding doc +% string. +% +% For the user to be able to specify anonymous arguments starting +% with a -, include for example ("-", String anon_fun, doc) in +% speclist. +% By default, parse recognizes two unit options, -help and --help, +% which will display usage_msg and the list of options, and exit +% the program. You can override this behaviour by specifying your +% own -help and --help options in speclist. +% +%<< +% val parse_argv : +% ?current:int Pervasives.ref -> +% string array -> +% (key * spec * doc) list -> anon_fun -> usage_msg -> unit +%>> +% +% Arg.parse_argv ~current args speclist anon_fun usage_msg parses +% the array args as if it were the command line. It uses and +% updates the value of ~current (if given), or Arg.current. You +% must set it before calling parse_argv. The initial value of +% current is the index of the program name (argument 0) in the +% array. If an error occurs, Arg.parse_argv raises Arg.Bad with +% the error message as argument. If option -help or --help is +% given, Arg.parse_argv raises Arg.Help with the help message as +% argument. +% +%<< +% exception Help of string +%>> +% +% Raised by Arg.parse_argv when the user asks for help. +% +%<< +% exception Bad of string +%>> +% +% Functions in spec or anon_fun can raise Arg.Bad with an error +% message to reject invalid arguments. Arg.Bad is also raised by +% Arg.parse_argv in case of an error. +% +%<< +% val usage : (key * spec * doc) list -> usage_msg -> unit +%>> +% +% Arg.usage speclist usage_msg prints an error message including +% the list of valid options. This is the same message that +% Arg.parse[20.1] prints in case of error. speclist and usage_msg +% are the same as for Arg.parse. +% +%<< +% val align : (key * spec * doc) list -> (key * spec * doc) list +%>> +% +% Align the documentation strings by inserting spaces at the +% first space, according to the length of the keyword. Use a +% space as the first character in a doc string if you want to +% align the whole string. The doc strings corresponding to Symbol +% arguments are not aligned. +% +%<< +% val current : int Pervasives.ref +%>> +% +% Position (in Sys.argv[20.34]) of the argument being processed. +% You can change this value, e.g. to force Arg.parse[20.1] to +% skip some arguments. Arg.parse[20.1] uses the initial value of +% Arg.current[20.1] as the index of argument 0 (the program name) +% and starts parsing arguments at the next element. +% +% +% +%20.2 Module Array : Array operations. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% 0.5cm +%<< +% val length : 'a array -> int +%>> +% +% Return the length (number of elements) of the given array. +% +%<< +% val get : 'a array -> int -> 'a +%>> +% +% Array.get a n returns the element number n of array a. The +% first element has number 0. The last element has number +% Array.length a - 1. You can also write a.(n) instead of +% Array.get a n. +% Raise Invalid_argument "index out of bounds" if n is outside +% the range 0 to (Array.length a - 1). +% +%<< +% val set : 'a array -> int -> 'a -> unit +%>> +% +% Array.set a n x modifies array a in place, replacing element +% number n with x. You can also write a.(n) <- x instead of +% Array.set a n x. +% Raise Invalid_argument "index out of bounds" if n is outside +% the range 0 to Array.length a - 1. +% +%<< +% val make : int -> 'a -> 'a array +%>> +% +% Array.make n x returns a fresh array of length n, initialized +% with x. All the elements of this new array are initially +% physically equal to x (in the sense of the == predicate). +% Consequently, if x is mutable, it is shared among all elements +% of the array, and modifying x through one of the array entries +% will modify all other entries at the same time. +% Raise Invalid_argument if n < 0 or n > Sys.max_array_length. If +% the value of x is a floating-point number, then the maximum +% size is only Sys.max_array_length / 2. +% +%<< +% val create : int -> 'a -> 'a array +%>> +% +% Deprecated. Array.create is an alias for Array.make[20.2]. +% +%<< +% val init : int -> (int -> 'a) -> 'a array +%>> +% +% Array.init n f returns a fresh array of length n, with element +% number i initialized to the result of f i. In other terms, +% Array.init n f tabulates the results of f applied to the +% integers 0 to n-1. +% Raise Invalid_argument if n < 0 or n > Sys.max_array_length. If +% the return type of f is float, then the maximum size is only +% Sys.max_array_length / 2. +% +%<< +% val make_matrix : int -> int -> 'a -> 'a array array +%>> +% +% Array.make_matrix dimx dimy e returns a two-dimensional array +% (an array of arrays) with first dimension dimx and second +% dimension dimy. All the elements of this new matrix are +% initially physically equal to e. The element (x,y) of a matrix +% m is accessed with the notation m.(x).(y). +% Raise Invalid_argument if dimx or dimy is negative or greater +% than Sys.max_array_length. If the value of e is a +% floating-point number, then the maximum size is only +% Sys.max_array_length / 2. +% +%<< +% val create_matrix : int -> int -> 'a -> 'a array array +%>> +% +% Deprecated. Array.create_matrix is an alias for +% Array.make_matrix[20.2]. +% +%<< +% val append : 'a array -> 'a array -> 'a array +%>> +% +% Array.append v1 v2 returns a fresh array containing the +% concatenation of the arrays v1 and v2. +% +%<< +% val concat : 'a array list -> 'a array +%>> +% +% Same as Array.append, but concatenates a list of arrays. +% +%<< +% val sub : 'a array -> int -> int -> 'a array +%>> +% +% Array.sub a start len returns a fresh array of length len, +% containing the elements number start to start + len - 1 of +% array a. +% Raise Invalid_argument "Array.sub" if start and len do not +% designate a valid subarray of a; that is, if start < 0, or len +% < 0, or start + len > Array.length a. +% +%<< +% val copy : 'a array -> 'a array +%>> +% +% Array.copy a returns a copy of a, that is, a fresh array +% containing the same elements as a. +% +%<< +% val fill : 'a array -> int -> int -> 'a -> unit +%>> +% +% Array.fill a ofs len x modifies the array a in place, storing +% x in elements number ofs to ofs + len - 1. +% Raise Invalid_argument "Array.fill" if ofs and len do not +% designate a valid subarray of a. +% +%<< +% val blit : 'a array -> int -> 'a array -> int -> int -> unit +%>> +% +% Array.blit v1 o1 v2 o2 len copies len elements from array v1, +% starting at element number o1, to array v2, starting at element +% number o2. It works correctly even if v1 and v2 are the same +% array, and the source and destination chunks overlap. +% Raise Invalid_argument "Array.blit" if o1 and len do not +% designate a valid subarray of v1, or if o2 and len do not +% designate a valid subarray of v2. +% +%<< +% val to_list : 'a array -> 'a list +%>> +% +% Array.to_list a returns the list of all the elements of a. +% +%<< +% val of_list : 'a list -> 'a array +%>> +% +% Array.of_list l returns a fresh array containing the elements +% of l. +% +%<< +% val iter : ('a -> unit) -> 'a array -> unit +%>> +% +% Array.iter f a applies function f in turn to all the elements +% of a. It is equivalent to f a.(0); f a.(1); ...; f +% a.(Array.length a - 1); (). +% +%<< +% val map : ('a -> 'b) -> 'a array -> 'b array +%>> +% +% Array.map f a applies function f to all the elements of a, and +% builds an array with the results returned by f: [| f a.(0); f +% a.(1); ...; f a.(Array.length a - 1) |]. +% +%<< +% val iteri : (int -> 'a -> unit) -> 'a array -> unit +%>> +% +% Same as Array.iter[20.2], but the function is applied to the +% index of the element as first argument, and the element itself +% as second argument. +% +%<< +% val mapi : (int -> 'a -> 'b) -> 'a array -> 'b array +%>> +% +% Same as Array.map[20.2], but the function is applied to the +% index of the element as first argument, and the element itself +% as second argument. +% +%<< +% val fold_left : ('a -> 'b -> 'a) -> 'a -> 'b array -> 'a +%>> +% +% Array.fold_left f x a computes f (... (f (f x a.(0)) a.(1)) +% ...) a.(n-1), where n is the length of the array a. +% +%<< +% val fold_right : ('a -> 'b -> 'b) -> 'a array -> 'b -> 'b +%>> +% +% Array.fold_right f a x computes f a.(0) (f a.(1) ( ... (f +% a.(n-1) x) ...)), where n is the length of the array a. +% +% +%Sorting +%======= +% +%<< +% val sort : ('a -> 'a -> int) -> 'a array -> unit +%>> +% +% Sort an array in increasing order according to a comparison +% function. The comparison function must return 0 if its arguments +% compare as equal, a positive integer if the first is greater, +% and a negative integer if the first is smaller (see below for a +% complete specification). For example, Pervasives.compare[19.2] +% is a suitable comparison function, provided there are no +% floating-point NaN values in the data. After calling +% Array.sort, the array is sorted in place in increasing order. +% Array.sort is guaranteed to run in constant heap space and (at +% most) logarithmic stack space. +% The current implementation uses Heap Sort. It runs in constant +% stack space. +% Specification of the comparison function: Let a be the array +% and cmp the comparison function. The following must be true for +% all x, y, z in a : +% +% - cmp x y > 0 if and only if cmp y x < 0 +% - if cmp x y >= 0 and cmp y z >= 0 then cmp x z >= 0 +% +% When Array.sort returns, a contains the same elements as before, +% reordered in such a way that for all i and j valid indices of a +% : +% +% - cmp a.(i) a.(j) >= 0 if and only if i >= j +% +%<< +% val stable_sort : ('a -> 'a -> int) -> 'a array -> unit +%>> +% +% Same as Array.sort[20.2], but the sorting algorithm is stable +% (i.e. elements that compare equal are kept in their original +% order) and not guaranteed to run in constant heap space. +% The current implementation uses Merge Sort. It uses n/2 words +% of heap space, where n is the length of the array. It is +% usually faster than the current implementation of +% Array.sort[20.2]. +% +%<< +% val fast_sort : ('a -> 'a -> int) -> 'a array -> unit +%>> +% +% Same as Array.sort[20.2] or Array.stable_sort[20.2], whichever +% is faster on typical input. +% +% +% +%20.3 Module Buffer : Extensible string buffers. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% This module implements string buffers that automatically expand as +%necessary. It provides accumulative concatenation of strings in quasi-linear +%time (instead of quadratic time when strings are concatenated pairwise). +% 0.5cm +%<< +% type t +%>> +% +% The abstract type of buffers. +% +%<< +% val create : int -> t +%>> +% +% create n returns a fresh buffer, initially empty. The n +% parameter is the initial size of the internal string that holds +% the buffer contents. That string is automatically reallocated +% when more than n characters are stored in the buffer, but +% shrinks back to n characters when reset is called. For best +% performance, n should be of the same order of magnitude as the +% number of characters that are expected to be stored in the +% buffer (for instance, 80 for a buffer that holds one output +% line). Nothing bad will happen if the buffer grows beyond that +% limit, however. In doubt, take n = 16 for instance. If n is not +% between 1 and Sys.max_string_length[20.34], it will be clipped +% to that interval. +% +%<< +% val contents : t -> string +%>> +% +% Return a copy of the current contents of the buffer. The +% buffer itself is unchanged. +% +%<< +% val sub : t -> int -> int -> string +%>> +% +% Buffer.sub b off len returns (a copy of) the substring of the +% current contents of the buffer b starting at offset off of +% length len bytes. May raise Invalid_argument if out of bounds +% request. The buffer itself is unaffected. +% +%<< +% val nth : t -> int -> char +%>> +% +% get the n-th character of the buffer. Raise Invalid_argument if +% index out of bounds +% +%<< +% val length : t -> int +%>> +% +% Return the number of characters currently contained in the +% buffer. +% +%<< +% val clear : t -> unit +%>> +% +% Empty the buffer. +% +%<< +% val reset : t -> unit +%>> +% +% Empty the buffer and deallocate the internal string holding the +% buffer contents, replacing it with the initial internal string +% of length n that was allocated by Buffer.create[20.3] n. For +% long-lived buffers that may have grown a lot, reset allows +% faster reclamation of the space used by the buffer. +% +%<< +% val add_char : t -> char -> unit +%>> +% +% add_char b c appends the character c at the end of the buffer +% b. +% +%<< +% val add_string : t -> string -> unit +%>> +% +% add_string b s appends the string s at the end of the buffer b. +% +%<< +% val add_substring : t -> string -> int -> int -> unit +%>> +% +% add_substring b s ofs len takes len characters from offset ofs +% in string s and appends them at the end of the buffer b. +% +%<< +% val add_substitute : t -> (string -> string) -> string -> unit +%>> +% +% add_substitute b f s appends the string pattern s at the end +% of the buffer b with substitution. The substitution process +% looks for variables into the pattern and substitutes each +% variable name by its value, as obtained by applying the mapping +% f to the variable name. Inside the string pattern, a variable +% name immediately follows a non-escaped $ character and is one +% of the following: +% +% - a non empty sequence of alphanumeric or _ characters, +% - an arbitrary sequence of characters enclosed by a pair of +% matching parentheses or curly brackets. An escaped $ +% character is a $ that immediately follows a backslash +% character; it then stands for a plain $. Raise Not_found if +% the closing character of a parenthesized variable cannot be +% found. +% +%<< +% val add_buffer : t -> t -> unit +%>> +% +% add_buffer b1 b2 appends the current contents of buffer b2 at +% the end of buffer b1. b2 is not modified. +% +%<< +% val add_channel : t -> Pervasives.in_channel -> int -> unit +%>> +% +% add_channel b ic n reads exactly n character from the input +% channel ic and stores them at the end of buffer b. Raise +% End_of_file if the channel contains fewer than n characters. +% +%<< +% val output_buffer : Pervasives.out_channel -> t -> unit +%>> +% +% output_buffer oc b writes the current contents of buffer b on +% the output channel oc. +% +% +% +%20.4 Module Callback : Registering Caml values with the C runtime. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* +% +% +% This module allows Caml values to be registered with the C runtime under a +%symbolic name, so that C code can later call back registered Caml functions, +%or raise registered Caml exceptions. +% 0.5cm +%<< +% val register : string -> 'a -> unit +%>> +% +% Callback.register n v registers the value v under the name n. +% C code can later retrieve a handle to v by calling +% caml_named_value(n). +% +%<< +% val register_exception : string -> exn -> unit +%>> +% +% Callback.register_exception n exn registers the exception +% contained in the exception value exn under the name n. C code +% can later retrieve a handle to the exception by calling +% caml_named_value(n). The exception value thus obtained is +% suitable for passign as first argument to raise_constant or +% raise_with_arg. +% +% +% +%20.5 Module Char : Character operations. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* +% +% +% 0.5cm +%<< +% val code : char -> int +%>> +% +% Return the ASCII code of the argument. +% +%<< +% val chr : int -> char +%>> +% +% Return the character with the given ASCII code. Raise +% Invalid_argument "Char.chr" if the argument is outside the +% range 0--255. +% +%<< +% val escaped : char -> string +%>> +% +% Return a string representing the given character, with special +% characters escaped following the lexical conventions of +% Objective Caml. +% +%<< +% val lowercase : char -> char +%>> +% +% Convert the given character to its equivalent lowercase +% character. +% +%<< +% val uppercase : char -> char +%>> +% +% Convert the given character to its equivalent uppercase +% character. +% +%<< +% type t = char +%>> +% +% An alias for the type of characters. +% +%<< +% val compare : t -> t -> int +%>> +% +% The comparison function for characters, with the same +% specification as Pervasives.compare[19.2]. Along with the type +% t, this function compare allows the module Char to be passed as +% argument to the functors Set.Make[20.28] and Map.Make[20.18]. +% +% +% +%20.6 Module Complex : Complex numbers. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* +% +% +% This module provides arithmetic operations on complex numbers. Complex +%numbers are represented by their real and imaginary parts (cartesian +%representation). Each part is represented by a double-precision floating-point +%number (type float). +% 0.5cm +%<< +% type t = { +% re : float ; +% im : float ; +% } +%>> +% +% The type of complex numbers. re is the real part and im the +% imaginary part. +% +%<< +% val zero : t +%>> +% +% The complex number 0. +% +%<< +% val one : t +%>> +% +% The complex number 1. +% +%<< +% val i : t +%>> +% +% The complex number i. +% +%<< +% val neg : t -> t +%>> +% +% Unary negation. +% +%<< +% val conj : t -> t +%>> +% +% Conjugate: given the complex x + i.y, returns x - i.y. +% +%<< +% val add : t -> t -> t +%>> +% +% Addition +% +%<< +% val sub : t -> t -> t +%>> +% +% Subtraction +% +%<< +% val mul : t -> t -> t +%>> +% +% Multiplication +% +%<< +% val inv : t -> t +%>> +% +% Multiplicative inverse (1/z). +% +%<< +% val div : t -> t -> t +%>> +% +% Division +% +%<< +% val sqrt : t -> t +%>> +% +% Square root. The result x + i.y is such that x > 0 or x = 0 +% and y >= 0. This function has a discontinuity along the +% negative real axis. +% +%<< +% val norm2 : t -> float +%>> +% +% Norm squared: given x + i.y, returns x^2 + y^2. +% +%<< +% val norm : t -> float +%>> +% +% Norm: given x + i.y, returns sqrt(x^2 + y^2). +% +%<< +% val arg : t -> float +%>> +% +% Argument. The argument of a complex number is the angle in the +% complex plane between the positive real axis and a line passing +% through zero and the number. This angle ranges from -pi to pi. +% This function has a discontinuity along the negative real axis. +% +%<< +% val polar : float -> float -> t +%>> +% +% polar norm arg returns the complex having norm norm and +% argument arg. +% +%<< +% val exp : t -> t +%>> +% +% Exponentiation. exp z returns e to the z power. +% +%<< +% val log : t -> t +%>> +% +% Natural logarithm (in base e). +% +%<< +% val pow : t -> t -> t +%>> +% +% Power function. pow z1 z2 returns z1 to the z2 power. +% +% +% +%20.7 Module Digest : MD5 message digest. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* +% +% +% This module provides functions to compute 128'bit --digests-- of +%arbitrary-length strings or files. The digests are of cryptographic quality: +%it is very hard, given a digest, to forge a string having that digest. The +%algorithm used is MD5. +% 0.5cm +%<< +% type t = string +%>> +% +% The type of digests: 16'character strings. +% +%<< +% val string : string -> t +%>> +% +% Return the digest of the given string. +% +%<< +% val substring : string -> int -> int -> t +%>> +% +% Digest.substring s ofs len returns the digest of the substring +% of s starting at character number ofs and containing len +% characters. +% +%<< +% val channel : Pervasives.in_channel -> int -> t +%>> +% +% If len is nonnegative, Digest.channel ic len reads len +% characters from channel ic and returns their digest, or raises +% End_of_file if end-of-file is reached before len characters are +% read. If len is negative, Digest.channel ic len reads all +% characters from ic until end-of-file is reached and return +% their digest. +% +%<< +% val file : string -> t +%>> +% +% Return the digest of the file whose name is given. +% +%<< +% val output : Pervasives.out_channel -> t -> unit +%>> +% +% Write a digest on the given output channel. +% +%<< +% val input : Pervasives.in_channel -> t +%>> +% +% Read a digest from the given input channel. +% +%<< +% val to_hex : t -> string +%>> +% +% Return the printable hexadecimal representation of the given +% digest. +% +% +% +%20.8 Module Filename : Operations on file names. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* +% +% +% 0.5cm +%<< +% val current_dir_name : string +%>> +% +% The conventional name for the current directory (e.g. . in +% Unix). +% +%<< +% val parent_dir_name : string +%>> +% +% The conventional name for the parent of the current directory +% (e.g. .. in Unix). +% +%<< +% val concat : string -> string -> string +%>> +% +% concat dir file returns a file name that designates file file +% in directory dir. +% +%<< +% val is_relative : string -> bool +%>> +% +% Return true if the file name is relative to the current +% directory, false if it is absolute (i.e. in Unix, starts with +% /). +% +%<< +% val is_implicit : string -> bool +%>> +% +% Return true if the file name is relative and does not start +% with an explicit reference to the current directory (./ or ../ +% in Unix), false if it starts with an explicit reference to the +% root directory or the current directory. +% +%<< +% val check_suffix : string -> string -> bool +%>> +% +% check_suffix name suff returns true if the filename name ends +% with the suffix suff. +% +%<< +% val chop_suffix : string -> string -> string +%>> +% +% chop_suffix name suff removes the suffix suff from the +% filename name. The behavior is undefined if name does not end +% with the suffix suff. +% +%<< +% val chop_extension : string -> string +%>> +% +% Return the given file name without its extension. The extension +% is the shortest suffix starting with a period and not including +% a directory separator, .xyz for instance. +% Raise Invalid_argument if the given name does not contain an +% extension. +% +%<< +% val basename : string -> string +%>> +% +% Split a file name into directory name / base file name. concat +% (dirname name) (basename name) returns a file name which is +% equivalent to name. Moreover, after setting the current +% directory to dirname name (with Sys.chdir[20.34]), references +% to basename name (which is a relative file name) designate the +% same file as name before the call to Sys.chdir[20.34]. +% The result is not specified if the argument is not a valid file +% name (for example, under Unix if there is a NUL character in +% the string). +% +%<< +% val dirname : string -> string +%>> +% +% See Filename.basename[20.8]. +% +%<< +% val temp_file : string -> string -> string +%>> +% +% temp_file prefix suffix returns the name of a fresh temporary +% file in the temporary directory. The base name of the temporary +% file is formed by concatenating prefix, then a suitably chosen +% integer number, then suffix. The temporary file is created +% empty, with permissions 0o600 (readable and writable only by +% the file owner). The file is guaranteed to be different from +% any other file that existed when temp_file was called. Under +% Unix, the temporary directory is /tmp by default; if set, the +% value of the environment variable TMPDIR is used instead. Under +% Windows, the name of the temporary directory is the value of +% the environment variable TEMP, or C:\temp by default. +% +%<< +% val open_temp_file : +% ?mode:Pervasives.open_flag list -> +% string -> string -> string * Pervasives.out_channel +%>> +% +% Same as Filename.temp_file[20.8], but returns both the name of +% a fresh temporary file, and an output channel opened +% (atomically) on this file. This function is more secure than +% temp_file: there is no risk that the temporary file will be +% modified (e.g. replaced by a symbolic link) before the program +% opens it. The optional argument mode is a list of additional +% flags to control the opening of the file. It can contain one or +% several of Open_append, Open_binary, and Open_text. The default +% is [Open_text] (open in text mode). +% +%<< +% val quote : string -> string +%>> +% +% Return a quoted version of a file name, suitable for use as +% one argument in a shell command line, escaping all shell +% meta'characters. +% +% +% +%20.9 Module Format : Pretty printing. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% This module implements a pretty-printing facility to format text within +%--pretty-printing boxes--. The pretty-printer breaks lines at specified break +%hints, and indents lines according to the box structure. +% For a gentle introduction to the basics of pretty-printing using Format, +%read +%http://caml.inria.fr/resources/doc/guides/format.html[http://caml.inria.fr/reso +%urces/doc/guides/format.html]. +% Warning: the material output by the following functions is delayed in the +%pretty-printer queue in order to compute the proper line breaking. Hence, you +%should not mix calls to the printing functions of the basic I/O system with +%calls to the functions of this module: this could result in some strange +%output seemingly unrelated with the evaluation order of printing commands. +% You may consider this module as providing an extension to the printf +%facility to provide automatic line breaking. The addition of pretty-printing +%annotations to your regular printf formats gives you fancy indentation and +%line breaks. Pretty-printing annotations are described below in the +%documentation of the function Format.fprintf[20.9]. +% You may also use the explicit box management and printing functions provided +%by this module. This style is more basic but more verbose than the fprintf +%concise formats. +% For instance, the sequence open_box 0; print_string "x ="; print_space (); +%print_int 1; close_box () that prints x = 1 within a pretty-printing box, can +%be abbreviated as printf "@[%s@ %i@]" "x =" 1, or even shorter printf "@[x =@ +%%i@]" 1. +% Rule of thumb for casual users of this library: +% +% - use simple boxes (as obtained by open_box 0); +% - use simple break hints (as obtained by print_cut () that outputs a simple +% break hint, or by print_space () that outputs a space indicating a break +% hint); +% - once a box is opened, display its material with basic printing functions +% (e. g. print_int and print_string); +% - when the material for a box has been printed, call close_box () to close +% the box; +% - at the end of your routine, evaluate print_newline () to close all +% remaining boxes and flush the pretty-printer. +% +% The behaviour of pretty-printing commands is unspecified if there is no +%opened pretty-printing box. Each box opened via one of the open_ functions +%below must be closed using close_box for proper formatting. Otherwise, some of +%the material printed in the boxes may not be output, or may be formatted +%incorrectly. +% In case of interactive use, the system closes all opened boxes and flushes +%all pending text (as with the print_newline function) after each phrase. Each +%phrase is therefore executed in the initial state of the pretty-printer. +% 0.5cm +% +%Boxes +%===== +% +%<< +% val open_box : int -> unit +%>> +% +% open_box d opens a new pretty-printing box with offset d. +% This box is the general purpose pretty-printing box. Material +% in this box is displayed --horizontal or vertical--: break +% hints inside the box may lead to a new line, if there is no +% more room on the line to print the remainder of the box, or if +% a new line may lead to a new indentation (demonstrating the +% indentation of the box). When a new line is printed in the box, +% d is added to the current indentation. +% +%<< +% val close_box : unit -> unit +%>> +% +% Closes the most recently opened pretty-printing box. +% +% +%Formatting functions +%==================== +% +%<< +% val print_string : string -> unit +%>> +% +% print_string str prints str in the current box. +% +%<< +% val print_as : int -> string -> unit +%>> +% +% print_as len str prints str in the current box. The +% pretty-printer formats str as if it were of length len. +% +%<< +% val print_int : int -> unit +%>> +% +% Prints an integer in the current box. +% +%<< +% val print_float : float -> unit +%>> +% +% Prints a floating point number in the current box. +% +%<< +% val print_char : char -> unit +%>> +% +% Prints a character in the current box. +% +%<< +% val print_bool : bool -> unit +%>> +% +% Prints a boolean in the current box. +% +% +%Break hints +%=========== +% +%<< +% val print_space : unit -> unit +%>> +% +% print_space () is used to separate items (typically to print a +% space between two words). It indicates that the line may be +% split at this point. It either prints one space or splits the +% line. It is equivalent to print_break 1 0. +% +%<< +% val print_cut : unit -> unit +%>> +% +% print_cut () is used to mark a good break position. It +% indicates that the line may be split at this point. It either +% prints nothing or splits the line. This allows line splitting +% at the current point, without printing spaces or adding +% indentation. It is equivalent to print_break 0 0. +% +%<< +% val print_break : int -> int -> unit +%>> +% +% Inserts a break hint in a pretty-printing box. print_break +% nspaces offset indicates that the line may be split (a newline +% character is printed) at this point, if the contents of the +% current box does not fit on the current line. If the line is +% split at that point, offset is added to the current +% indentation. If the line is not split, nspaces spaces are +% printed. +% +%<< +% val print_flush : unit -> unit +%>> +% +% Flushes the pretty printer: all opened boxes are closed, and +% all pending text is displayed. +% +%<< +% val print_newline : unit -> unit +%>> +% +% Equivalent to print_flush followed by a new line. +% +%<< +% val force_newline : unit -> unit +%>> +% +% Forces a newline in the current box. Not the normal way of +% pretty-printing, you should prefer break hints. +% +%<< +% val print_if_newline : unit -> unit +%>> +% +% Executes the next formatting command if the preceding line has +% just been split. Otherwise, ignore the next formatting command. +% +% +%Margin +%====== +% +%<< +% val set_margin : int -> unit +%>> +% +% set_margin d sets the value of the right margin to d (in +% characters): this value is used to detect line overflows that +% leads to split lines. Nothing happens if d is smaller than 2. +% If d is too large, the right margin is set to the maximum +% admissible value (which is greater than 10^10). +% +%<< +% val get_margin : unit -> int +%>> +% +% Returns the position of the right margin. +% +% +%Maximum indentation limit +%========================= +% +%<< +% val set_max_indent : int -> unit +%>> +% +% set_max_indent d sets the value of the maximum indentation +% limit to d (in characters): once this limit is reached, boxes +% are rejected to the left, if they do not fit on the current +% line. Nothing happens if d is smaller than 2. If d is too +% large, the limit is set to the maximum admissible value (which +% is greater than 10^10). +% +%<< +% val get_max_indent : unit -> int +%>> +% +% Return the value of the maximum indentation limit (in +% characters). +% +% +%Formatting depth: maximum number of boxes allowed before ellipsis +%================================================================= +% +%<< +% val set_max_boxes : int -> unit +%>> +% +% set_max_boxes max sets the maximum number of boxes +% simultaneously opened. Material inside boxes nested deeper is +% printed as an ellipsis (more precisely as the text returned by +% get_ellipsis_text ()). Nothing happens if max is smaller than +% 2. +% +%<< +% val get_max_boxes : unit -> int +%>> +% +% Returns the maximum number of boxes allowed before ellipsis. +% +%<< +% val over_max_boxes : unit -> bool +%>> +% +% Tests if the maximum number of boxes allowed have already been +% opened. +% +% +%Advanced formatting +%=================== +% +%<< +% val open_hbox : unit -> unit +%>> +% +% open_hbox () opens a new pretty-printing box. This box is +% --horizontal--: the line is not split in this box (new lines +% may still occur inside boxes nested deeper). +% +%<< +% val open_vbox : int -> unit +%>> +% +% open_vbox d opens a new pretty-printing box with offset d. +% This box is --vertical--: every break hint inside this box +% leads to a new line. When a new line is printed in the box, d +% is added to the current indentation. +% +%<< +% val open_hvbox : int -> unit +%>> +% +% open_hvbox d opens a new pretty-printing box with offset d. +% This box is --horizontal-vertical--: it behaves as an +% --horizontal-- box if it fits on a single line, otherwise it +% behaves as a --vertical-- box. When a new line is printed in +% the box, d is added to the current indentation. +% +%<< +% val open_hovbox : int -> unit +%>> +% +% open_hovbox d opens a new pretty-printing box with offset d. +% This box is --horizontal or vertical--: break hints inside this +% box may lead to a new line, if there is no more room on the +% line to print the remainder of the box. When a new line is +% printed in the box, d is added to the current indentation. +% +% +%Tabulations +%=========== +% +%<< +% val open_tbox : unit -> unit +%>> +% +% Opens a tabulation box. +% +%<< +% val close_tbox : unit -> unit +%>> +% +% Closes the most recently opened tabulation box. +% +%<< +% val print_tbreak : int -> int -> unit +%>> +% +% Break hint in a tabulation box. print_tbreak spaces offset +% moves the insertion point to the next tabulation (spaces being +% added to this position). Nothing occurs if insertion point is +% already on a tabulation mark. If there is no next tabulation +% on the line, then a newline is printed and the insertion point +% moves to the first tabulation of the box. If a new line is +% printed, offset is added to the current indentation. +% +%<< +% val set_tab : unit -> unit +%>> +% +% Sets a tabulation mark at the current insertion point. +% +%<< +% val print_tab : unit -> unit +%>> +% +% print_tab () is equivalent to print_tbreak (0,0). +% +% +%Ellipsis +%======== +% +%<< +% val set_ellipsis_text : string -> unit +%>> +% +% Set the text of the ellipsis printed when too many boxes are +% opened (a single dot, ., by default). +% +%<< +% val get_ellipsis_text : unit -> string +%>> +% +% Return the text of the ellipsis. +% +% +%Tags +%==== +% +%<< +% type tag = string +%>> +% +% Tags are used to decorate printed entities for user-s defined purposes, e.g. +%setting font and giving size indications for a display device, or marking +%delimitations of semantics entities (e.g. HTML or TeX elements or terminal +%escape sequences). +% By default, those tags do not influence line breaking calculation: the tag +%--markers-- are not considered as part of the printing material that drives +%line breaking (in other words, the length of those strings is considered as +%zero for line breaking). +% Thus, tag handling is in some sense transparent to pretty-printing and does +%not interfere with usual pretty-printing. Hence, a single pretty printing +%routine can output both simple --verbatim-- material or richer decorated +%output depending on the treatment of tags. By default, tags are not active, +%hence the output is not decorated with tag information. Once set_tags is set +%to true, the pretty printer engine honors tags and decorates the output +%accordingly. +% When a tag has been opened (or closed), it is both and successively +%--printed-- and --marked--. Printing a tag means calling a formatter specific +%function with the name of the tag as argument: that --tag printing-- function +%can then print any regular material to the formatter (so that this material is +%enqueued as usual in the formatter queue for further line'breaking +%computation). Marking a tag means to output an arbitrary string (the --tag +%marker--), directly into the output device of the formatter. Hence, the +%formatter specific --tag marking-- function must return the tag marker string +%associated to its tag argument. Being flushed directly into the output device +%of the formatter, tag marker strings are not considered as part of the +%printing material that drives line breaking (in other words, the length of the +%strings corresponding to tag markers is considered as zero for line +%breaking). In addition, advanced users may take advantage of the specificity +%of tag markers to be precisely output when the pretty printer has already +%decided where to break the lines, and precisely when the queue is flushed into +%the output device. +% In the spirit of HTML tags, the default tag marking functions output tags +%enclosed in "<" and ">": hence, the opening marker of tag t is "" and the +%closing marker "". +% Default tag printing functions just do nothing. +% Tag marking and tag printing functions are user definable and can be set by +%calling set_formatter_tag_functions. +%<< +% val open_tag : tag -> unit +%>> +% +% open_tag t opens the tag named t; the print_open_tag function +% of the formatter is called with t as argument; the tag marker +% mark_open_tag t will be flushed into the output device of the +% formatter. +% +%<< +% val close_tag : unit -> unit +%>> +% +% close_tag () closes the most recently opened tag t. In +% addition, the print_close_tag function of the formatter is +% called with t as argument. The marker mark_close_tag t will be +% flushed into the output device of the formatter. +% +%<< +% val set_tags : bool -> unit +%>> +% +% set_tags b turns on or off the treatment of tags (default is +% off). +% +%<< +% val set_print_tags : bool -> unit +%>> +% +%<< +% val set_mark_tags : bool -> unit +%>> +% +% set_print_tags b turns on or off the printing of tags, while +% set_mark_tags b turns on or off the output of tag markers. +% +%<< +% val get_print_tags : unit -> bool +%>> +% +%<< +% val get_mark_tags : unit -> bool +%>> +% +% Return the current status of tags printing and tags marking. +% +% +%Redirecting formatter output +%============================ +% +%<< +% val set_formatter_out_channel : Pervasives.out_channel -> unit +%>> +% +% Redirect the pretty-printer output to the given channel. +% +%<< +% val set_formatter_output_functions : +% (string -> int -> int -> unit) -> (unit -> unit) -> unit +%>> +% +% set_formatter_output_functions out flush redirects the +% pretty-printer output to the functions out and flush. +% The out function performs the pretty-printer output. It is +% called with a string s, a start position p, and a number of +% characters n; it is supposed to output characters p to p + n - +% 1 of s. The flush function is called whenever the +% pretty-printer is flushed using print_flush or print_newline. +% +%<< +% val get_formatter_output_functions : +% unit -> (string -> int -> int -> unit) * (unit -> unit) +%>> +% +% Return the current output functions of the pretty-printer. +% +% +%Changing the meaning of printing tags +%===================================== +% +%<< +% type formatter_tag_functions = { +% mark_open_tag : tag -> string ; +% mark_close_tag : tag -> string ; +% print_open_tag : tag -> unit ; +% print_close_tag : tag -> unit ; +% } +%>> +% +% The tag handling functions specific to a formatter: mark +% versions are the --tag marking-- functions that associate a +% string marker to a tag in order for the pretty-printing engine +% to flush those markers as 0 length tokens in the output device +% of the formatter. print versions are the --tag printing-- +% functions that can perform regular printing when a tag is +% closed or opened. +% +%<< +% val set_formatter_tag_functions : formatter_tag_functions -> unit +%>> +% +% set_formatter_tag_functions tag_funs changes the meaning of opening and +%closing tags to use the functions in tag_funs. +% When opening a tag name t, the string t is passed to the opening tag marking +%function (the mark_open_tag field of the record tag_funs), that must return +%the opening tag marker for that name. When the next call to close_tag () +%happens, the tag name t is sent back to the closing tag marking function (the +%mark_close_tag field of record tag_funs), that must return a closing tag +%marker for that name. +% The print_ field of the record contains the functions that are called at tag +%opening and tag closing time, to output regular material in the pretty-printer +%queue. +%<< +% val get_formatter_tag_functions : unit -> formatter_tag_functions +%>> +% +% Return the current tag functions of the pretty-printer. +% +% +%Changing the meaning of pretty printing (indentation, line breaking, and +%======================================================================== +%printing material) +%================== +% +%<< +% val set_all_formatter_output_functions : +% out:(string -> int -> int -> unit) -> +% flush:(unit -> unit) -> +% newline:(unit -> unit) -> spaces:(int -> unit) -> unit +%>> +% +% set_all_formatter_output_functions out flush outnewline +% outspace redirects the pretty-printer output to the functions +% out and flush as described in set_formatter_output_functions. +% In addition, the pretty-printer function that outputs a newline +% is set to the function outnewline and the function that outputs +% indentation spaces is set to the function outspace. +% This way, you can change the meaning of indentation (which can +% be something else than just printing space characters) and the +% meaning of new lines opening (which can be connected to any +% other action needed by the application at hand). The two +% functions outspace and outnewline are normally connected to out +% and flush: respective default values for outspace and +% outnewline are out (String.make n - -) 0 n and out "\n" 0 1. +% +%<< +% val get_all_formatter_output_functions : +% unit -> +% (string -> int -> int -> unit) * (unit -> unit) * (unit -> unit) * +% (int -> unit) +%>> +% +% Return the current output functions of the pretty-printer, +% including line breaking and indentation functions. +% +% +%Multiple formatted output +%========================= +% +%<< +% type formatter +%>> +% +% Abstract data type corresponding to a pretty-printer (also +% called a formatter) and all its machinery. Defining new +% pretty-printers permits the output of material in parallel on +% several channels. Parameters of a pretty-printer are local to +% this pretty-printer: margin, maximum indentation limit, maximum +% number of boxes simultaneously opened, ellipsis, and so on, are +% specific to each pretty-printer and may be fixed independently. +% Given an output channel oc, a new formatter writing to that +% channel is obtained by calling formatter_of_out_channel oc. +% Alternatively, the make_formatter function allocates a new +% formatter with explicit output and flushing functions +% (convenient to output material to strings for instance). +% +%<< +% val formatter_of_out_channel : Pervasives.out_channel -> formatter +%>> +% +% formatter_of_out_channel oc returns a new formatter that +% writes to the corresponding channel oc. +% +%<< +% val std_formatter : formatter +%>> +% +% The standard formatter used by the formatting functions above. +% It is defined as formatter_of_out_channel stdout. +% +%<< +% val err_formatter : formatter +%>> +% +% A formatter to use with formatting functions below for output +% to standard error. It is defined as formatter_of_out_channel +% stderr. +% +%<< +% val formatter_of_buffer : Buffer.t -> formatter +%>> +% +% formatter_of_buffer b returns a new formatter writing to +% buffer b. As usual, the formatter has to be flushed at the end +% of pretty printing, using pp_print_flush or pp_print_newline, +% to display all the pending material. +% +%<< +% val stdbuf : Buffer.t +%>> +% +% The string buffer in which str_formatter writes. +% +%<< +% val str_formatter : formatter +%>> +% +% A formatter to use with formatting functions below for output +% to the stdbuf string buffer. str_formatter is defined as +% formatter_of_buffer stdbuf. +% +%<< +% val flush_str_formatter : unit -> string +%>> +% +% Returns the material printed with str_formatter, flushes the +% formatter and resets the corresponding buffer. +% +%<< +% val make_formatter : +% (string -> int -> int -> unit) -> (unit -> unit) -> formatter +%>> +% +% make_formatter out flush returns a new formatter that writes +% according to the output function out, and the flushing function +% flush. Hence, a formatter to the out channel oc is returned by +% make_formatter (output oc) (fun () -> flush oc). +% +% +%Basic functions to use with formatters +%====================================== +% +%<< +% val pp_open_hbox : formatter -> unit -> unit +%>> +% +%<< +% val pp_open_vbox : formatter -> int -> unit +%>> +% +%<< +% val pp_open_hvbox : formatter -> int -> unit +%>> +% +%<< +% val pp_open_hovbox : formatter -> int -> unit +%>> +% +%<< +% val pp_open_box : formatter -> int -> unit +%>> +% +%<< +% val pp_close_box : formatter -> unit -> unit +%>> +% +%<< +% val pp_open_tag : formatter -> string -> unit +%>> +% +%<< +% val pp_close_tag : formatter -> unit -> unit +%>> +% +%<< +% val pp_print_string : formatter -> string -> unit +%>> +% +%<< +% val pp_print_as : formatter -> int -> string -> unit +%>> +% +%<< +% val pp_print_int : formatter -> int -> unit +%>> +% +%<< +% val pp_print_float : formatter -> float -> unit +%>> +% +%<< +% val pp_print_char : formatter -> char -> unit +%>> +% +%<< +% val pp_print_bool : formatter -> bool -> unit +%>> +% +%<< +% val pp_print_break : formatter -> int -> int -> unit +%>> +% +%<< +% val pp_print_cut : formatter -> unit -> unit +%>> +% +%<< +% val pp_print_space : formatter -> unit -> unit +%>> +% +%<< +% val pp_force_newline : formatter -> unit -> unit +%>> +% +%<< +% val pp_print_flush : formatter -> unit -> unit +%>> +% +%<< +% val pp_print_newline : formatter -> unit -> unit +%>> +% +%<< +% val pp_print_if_newline : formatter -> unit -> unit +%>> +% +%<< +% val pp_open_tbox : formatter -> unit -> unit +%>> +% +%<< +% val pp_close_tbox : formatter -> unit -> unit +%>> +% +%<< +% val pp_print_tbreak : formatter -> int -> int -> unit +%>> +% +%<< +% val pp_set_tab : formatter -> unit -> unit +%>> +% +%<< +% val pp_print_tab : formatter -> unit -> unit +%>> +% +%<< +% val pp_set_tags : formatter -> bool -> unit +%>> +% +%<< +% val pp_set_print_tags : formatter -> bool -> unit +%>> +% +%<< +% val pp_set_mark_tags : formatter -> bool -> unit +%>> +% +%<< +% val pp_get_print_tags : formatter -> unit -> bool +%>> +% +%<< +% val pp_get_mark_tags : formatter -> unit -> bool +%>> +% +%<< +% val pp_set_margin : formatter -> int -> unit +%>> +% +%<< +% val pp_get_margin : formatter -> unit -> int +%>> +% +%<< +% val pp_set_max_indent : formatter -> int -> unit +%>> +% +%<< +% val pp_get_max_indent : formatter -> unit -> int +%>> +% +%<< +% val pp_set_max_boxes : formatter -> int -> unit +%>> +% +%<< +% val pp_get_max_boxes : formatter -> unit -> int +%>> +% +%<< +% val pp_over_max_boxes : formatter -> unit -> bool +%>> +% +%<< +% val pp_set_ellipsis_text : formatter -> string -> unit +%>> +% +%<< +% val pp_get_ellipsis_text : formatter -> unit -> string +%>> +% +%<< +% val pp_set_formatter_out_channel : +% formatter -> Pervasives.out_channel -> unit +%>> +% +%<< +% val pp_set_formatter_output_functions : +% formatter -> (string -> int -> int -> unit) -> (unit -> unit) -> unit +%>> +% +%<< +% val pp_get_formatter_output_functions : +% formatter -> unit -> (string -> int -> int -> unit) * (unit -> unit) +%>> +% +%<< +% val pp_set_all_formatter_output_functions : +% formatter -> +% out:(string -> int -> int -> unit) -> +% flush:(unit -> unit) -> +% newline:(unit -> unit) -> spaces:(int -> unit) -> unit +%>> +% +%<< +% val pp_get_all_formatter_output_functions : +% formatter -> +% unit -> +% (string -> int -> int -> unit) * (unit -> unit) * (unit -> unit) * +% (int -> unit) +%>> +% +%<< +% val pp_set_formatter_tag_functions : +% formatter -> formatter_tag_functions -> unit +%>> +% +%<< +% val pp_get_formatter_tag_functions : +% formatter -> unit -> formatter_tag_functions +%>> +% +% These functions are the basic ones: usual functions operating +% on the standard formatter are defined via partial evaluation of +% these primitives. For instance, print_string is equal to +% pp_print_string std_formatter. +% +% +%printf like functions for pretty-printing. +%========================================== +% +%<< +% val fprintf : formatter -> ('a, formatter, unit) Pervasives.format -> 'a +%>> +% +% fprintf ff format arg1 ... argN formats the arguments arg1 to +% argN according to the format string format, and outputs the +% resulting string on the formatter ff. The format is a character +% string which contains three types of objects: plain characters +% and conversion specifications as specified in the printf +% module, and pretty-printing indications. The pretty-printing +% indication characters are introduced by a @ character, and +% their meanings are: +% +% - @[: open a pretty-printing box. The type and offset of the +% box may be optionally specified with the following syntax: +% the < character, followed by an optional box type indication, +% then an optional integer offset, and the closing > +% character. Box type is one of h, v, hv, b, or hov, which +% stand respectively for an horizontal box, a vertical box, an +% --horizontal-vertical-- box, or an --horizontal or +% vertical-- box (b standing for an --horizontal or vertical-- +% box demonstrating indentation and hov standing for a +% regular--horizontal or vertical-- box). For instance, @[ opens an --horizontal or vertical-- box with indentation +% 2 as obtained with open_hovbox 2. For more details about +% boxes, see the various box opening functions open_*box. +% - @]: close the most recently opened pretty-printing box. +% - @,: output a good break as with print_cut (). +% - @ : output a space, as with print_space (). +% - @\n: force a newline, as with force_newline (). +% - @;: output a good break as with print_break. The nspaces and +% offset parameters of the break may be optionally specified +% with the following syntax: the < character, followed by an +% integer nspaces value, then an integer offset, and a closing +% > character. If no parameters are provided, the good break +% defaults to a space. +% - @?: flush the pretty printer as with print_flush (). This is +% equivalent to the conversion %!. +% - @.: flush the pretty printer and output a new line, as with +% print_newline (). +% - @: print the following item as if it were of length n. +% Hence, printf "@<0>%s" arg is equivalent to print_as 0 arg. +% If @ is not followed by a conversion specification, then +% the following character of the format is printed as if it +% were of length n. +% - @{: open a tag. The name of the tag may be optionally +% specified with the following syntax: the < character, +% followed by an optional string specification, and the +% closing > character. The string specification is any +% character string that does not contain the closing character +% ->-. If omitted, the tag name defaults to the empty string. +% For more details about tags, see the functions open_tag and +% close_tag. +% - @}: close the most recently opened tag. +% - @@: print a plain @ character. +% +% Example: printf "@[%s@ %d@]" "x =" 1 is equivalent to open_box +% (); print_string "x ="; print_space (); print_int 1; close_box +% (). It prints x = 1 within a pretty-printing box. +% +%<< +% val printf : ('a, formatter, unit) Pervasives.format -> 'a +%>> +% +% Same as fprintf above, but output on std_formatter. +% +%<< +% val eprintf : ('a, formatter, unit) Pervasives.format -> 'a +%>> +% +% Same as fprintf above, but output on err_formatter. +% +%<< +% val sprintf : ('a, unit, string) Pervasives.format -> 'a +%>> +% +% Same as printf above, but instead of printing on a formatter, +% returns a string containing the result of formatting the +% arguments. Note that the pretty-printer queue is flushed at the +% end of each call to sprintf. +% In case of multiple and related calls to sprintf to output +% material on a single string, you should consider using fprintf +% with a formatter writing to a buffer: flushing the buffer at the +% end of pretty-printing returns the desired string. You can also +% use the predefined formatter str_formatter and call +% flush_str_formatter () to get the result. +% +%<< +% val bprintf : Buffer.t -> ('a, formatter, unit) Pervasives.format -> 'a +%>> +% +% Same as sprintf above, but instead of printing on a string, +% writes into the given extensible buffer. As for sprintf, the +% pretty-printer queue is flushed at the end of each call to +% bprintf. +% In case of multiple and related calls to bprintf to output +% material on the same buffer b, you should consider using +% fprintf with a formatter writing to the buffer b (as obtained +% by formatter_of_buffer b), otherwise the repeated flushes of the +% pretty-printer queue would result in unexpected and badly +% formatted output. +% +%<< +% val kfprintf : +% (formatter -> 'a) -> +% formatter -> ('b, formatter, unit, 'a) format4 -> 'b +%>> +% +% Same as fprintf above, but instead of returning immediately, +% passes the formatter to its first argument at the end of +% printing. +% +%<< +% val ksprintf : (string -> 'a) -> ('b, unit, string, 'a) format4 -> 'b +%>> +% +% Same as sprintf above, but instead of returning the string, +% passes it to the first argument. +% +%<< +% val kprintf : (string -> 'a) -> ('b, unit, string, 'a) format4 -> 'b +%>> +% +% A deprecated synonym for ksprintf. +% +% +% +%20.10 Module Gc : Memory management control and statistics; finalised values. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% 0.5cm +%<< +% type stat = { +% minor_words : float ; +%>> +% +% Number of words allocated in the minor heap since the program +% was started.

In all cases, the result is +% the computed slice size. +% +%<< +% val major : unit -> unit +%>> +% +% Do a minor collection and finish the current major collection +% cycle. +% +%<< +% val full_major : unit -> unit +%>> +% +% Do a minor collection, finish the current major collection +% cycle, and perform a complete new cycle. This will collect all +% currently unreachable blocks. +% +%<< +% val compact : unit -> unit +%>> +% +% Perform a full major collection and compact the heap. Note that +% heap compaction is a lengthy operation. +% +%<< +% val print_stat : Pervasives.out_channel -> unit +%>> +% +% Print the current values of the memory management counters (in +% human-readable form) into the channel argument. +% +%<< +% val allocated_bytes : unit -> float +%>> +% +% Return the total number of bytes allocated since the program +% was started. It is returned as a float to avoid overflow +% problems with int on 32'bit machines. +% +%<< +% val finalise : ('a -> unit) -> 'a -> unit +%>> +% +% finalise f v registers f as a finalisation function for v. v +% must be heap'allocated. f will be called with v as argument at +% some point between the first time v becomes unreachable and the +% time v is collected by the GC. Several functions can be +% registered for the same value, or even several instances of the +% same function. Each instance will be called once (or never, if +% the program terminates before v becomes unreachable). +% The GC will call the finalisation functions in the order of +% deallocation. When several values become unreachable at the +% same time (i.e. during the same GC cycle), the finalisation +% functions will be called in the reverse order of the +% corresponding calls to finalise. If finalise is called in the +% same order as the values are allocated, that means each value +% is finalised before the values it depends upon. Of course, this +% becomes false if additional dependencies are introduced by +% assignments. +% Anything reachable from the closure of finalisation functions +% is considered reachable, so the following code will not work as +% expected: +% +% - let v = ... in Gc.finalise (fun x -> ...) v +% +% Instead you should write: +% +% - let f = fun x -> ... ;; let v = ... in Gc.finalise f v +% +% The f function can use all features of O'caml, including +% assignments that make the value reachable again. It can also +% loop forever (in this case, the other finalisation functions +% will be called during the execution of f). It can call finalise +% on v or other values to register other functions or even +% itself. It can raise an exception; in this case the exception +% will interrupt whatever the program was doing when the function +% was called. +% finalise will raise Invalid_argument if v is not +% heap'allocated. Some examples of values that are not +% heap'allocated are integers, constant constructors, booleans, +% the empty array, the empty list, the unit value. The exact list +% of what is heap'allocated or not is implementation-dependent. +% Some constant values can be heap'allocated but never deallocated +% during the lifetime of the program, for example a list of +% integer constants; this is also implementation-dependent. You +% should also be aware that compiler optimisations may duplicate +% some immutable values, for example floating-point numbers when +% stored into arrays, so they can be finalised and collected while +% another copy is still in use by the program. +% The results of calling String.make[20.33], String.create[20.33], +% Array.make[20.2], and Pervasives.ref[19.2] are guaranteed to be +% heap'allocated and non'constant except when the length argument +% is 0. +% +%<< +% val finalise_release : unit -> unit +%>> +% +% A finalisation function may call finalise_release to tell the +% GC that it can launch the next finalisation function without +% waiting for the current one to return. +% +%<< +% type alarm +%>> +% +% An alarm is a piece of data that calls a user function at the +% end of each major GC cycle. The following functions are +% provided to create and delete alarms. +% +%<< +% val create_alarm : (unit -> unit) -> alarm +%>> +% +% create_alarm f will arrange for f to be called at the end of +% each major GC cycle, starting with the current cycle or the +% next one. A value of type alarm is returned that you can use +% to call delete_alarm. +% +%<< +% val delete_alarm : alarm -> unit +%>> +% +% delete_alarm a will stop the calls to the function associated +% to a. Calling delete_alarm a again has no effect. +% +% +% +%20.11 Module Genlex : A generic lexical analyzer. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% This module implements a simple --standard-- lexical analyzer, presented as +%a function from character streams to token streams.

The lexical classes are: Int and Float for +% integer and floating-point numbers; String for string literals, +% enclosed in double quotes; Char for character literals, +% enclosed in single quotes; Ident for identifiers (either +% sequences of letters, digits, underscores and quotes, or +% sequences of --operator characters-- such as +, *, etc); and +% Kwd for keywords (either identifiers or single --special +% characters-- such as (, }, etc). +% +%<< +% val make_lexer : string list -> char Stream.t -> token Stream.t +%>> +% +% Construct the lexer function. The first argument is the list of +% keywords. An identifier s is returned as Kwd s if s belongs to +% this list, and as Ident s otherwise. A special character s is +% returned as Kwd s if s belongs to this list, and cause a +% lexical error (exception Parse_error) otherwise. Blanks and +% newlines are skipped. Comments delimited by (* and *) are +% skipped as well, and can be nested. +% +% +% +%20.12 Module Hashtbl : Hash tables and hash functions. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* +% +% +% Hash tables are hashed association tables, with in-place modification. +% 0.5cm +% +%Generic interface +%================= +% +%<< +% type ('a, 'b) t +%>> +% +% The type of hash tables from type 'a to type 'b. +% +%<< +% val create : int -> ('a, 'b) t +%>> +% +% Hashtbl.create n creates a new, empty hash table, with initial +% size n. For best results, n should be on the order of the +% expected number of elements that will be in the table. The +% table grows as needed, so n is just an initial guess. +% +%<< +% val clear : ('a, 'b) t -> unit +%>> +% +% Empty a hash table. +% +%<< +% val add : ('a, 'b) t -> 'a -> 'b -> unit +%>> +% +% Hashtbl.add tbl x y adds a binding of x to y in table tbl. +% Previous bindings for x are not removed, but simply hidden. +% That is, after performing Hashtbl.remove[20.12] tbl x, the +% previous binding for x, if any, is restored. (Same behavior as +% with association lists.) +% +%<< +% val copy : ('a, 'b) t -> ('a, 'b) t +%>> +% +% Return a copy of the given hashtable. +% +%<< +% val find : ('a, 'b) t -> 'a -> 'b +%>> +% +% Hashtbl.find tbl x returns the current binding of x in tbl, or +% raises Not_found if no such binding exists. +% +%<< +% val find_all : ('a, 'b) t -> 'a -> 'b list +%>> +% +% Hashtbl.find_all tbl x returns the list of all data associated +% with x in tbl. The current binding is returned first, then the +% previous bindings, in reverse order of introduction in the +% table. +% +%<< +% val mem : ('a, 'b) t -> 'a -> bool +%>> +% +% Hashtbl.mem tbl x checks if x is bound in tbl. +% +%<< +% val remove : ('a, 'b) t -> 'a -> unit +%>> +% +% Hashtbl.remove tbl x removes the current binding of x in tbl, +% restoring the previous binding if it exists. It does nothing if +% x is not bound in tbl. +% +%<< +% val replace : ('a, 'b) t -> 'a -> 'b -> unit +%>> +% +% Hashtbl.replace tbl x y replaces the current binding of x in +% tbl by a binding of x to y. If x is unbound in tbl, a binding +% of x to y is added to tbl. This is functionally equivalent to +% Hashtbl.remove[20.12] tbl x followed by Hashtbl.add[20.12] tbl +% x y. +% +%<< +% val iter : ('a -> 'b -> unit) -> ('a, 'b) t -> unit +%>> +% +% Hashtbl.iter f tbl applies f to all bindings in table tbl. f +% receives the key as first argument, and the associated value as +% second argument. Each binding is presented exactly once to f. +% The order in which the bindings are passed to f is unspecified. +% However, if the table contains several bindings for the same +% key, they are passed to f in reverse order of introduction, +% that is, the most recent binding is passed first. +% +%<< +% val fold : ('a -> 'b -> 'c -> 'c) -> ('a, 'b) t -> 'c -> 'c +%>> +% +% Hashtbl.fold f tbl init computes (f kN dN ... (f k1 d1 +% init)...), where k1 ... kN are the keys of all bindings in tbl, +% and d1 ... dN are the associated values. Each binding is +% presented exactly once to f. The order in which the bindings +% are passed to f is unspecified. However, if the table contains +% several bindings for the same key, they are passed to f in +% reverse order of introduction, that is, the most recent binding +% is passed first. +% +%<< +% val length : ('a, 'b) t -> int +%>> +% +% Hashtbl.length tbl returns the number of bindings in tbl. +% Multiple bindings are counted multiply, so Hashtbl.length gives +% the number of times Hashtbl.iter calls its first argument. +% +% +%Functorial interface +%==================== +% +%<< +% module type HashedType = >> +% +% sig +% +% +% << +% type t +% >> +% +% The type of the hashtable keys. +% +% << +% val equal : t -> t -> bool +% >> +% +% The equality predicate used to compare keys. +% +% << +% val hash : t -> int +% >> +% +% A hashing function on keys.

Examples: suitable (equal, +% hash) pairs for arbitrary key types include ((=), +% Hashtbl.hash[20.12]) for comparing objects by structure, +% ((fun x y -> compare x y = 0), Hashtbl.hash[20.12]) for +% comparing objects by structure and handling +% Pervasives.nan[19.2] correctly, and ((==), +% Hashtbl.hash[20.12]) for comparing objects by addresses +% (e.g. for cyclic keys). +% +% +% - end +% +% The input signature of the functor Hashtbl.Make[20.12]. +% +%<< +% module type S = >> +% +% sig +% +% +% << +% type key +% >> +% +% << +% type 'a t +% >> +% +% << +% val create : int -> 'a t +% >> +% +% << +% val clear : 'a t -> unit +% >> +% +% << +% val copy : 'a t -> 'a t +% >> +% +% << +% val add : 'a t -> key -> 'a -> unit +% >> +% +% << +% val remove : 'a t -> key -> unit +% >> +% +% << +% val find : 'a t -> key -> 'a +% >> +% +% << +% val find_all : 'a t -> key -> 'a list +% >> +% +% << +% val replace : 'a t -> key -> 'a -> unit +% >> +% +% << +% val mem : 'a t -> key -> bool +% >> +% +% << +% val iter : (key -> 'a -> unit) -> 'a t -> unit +% >> +% +% << +% val fold : (key -> 'a -> 'b -> 'b) -> 'a t -> 'b -> 'b +% >> +% +% << +% val length : 'a t -> int +% >> +% +% - end +% +% The output signature of the functor Hashtbl.Make[20.12]. +% +%<< +% module Make : >> +% +% functor (H : HashedType) -> S with type key = H.t +% Functor building an implementation of the hashtable structure. +% The functor Hashtbl.Make returns a structure containing a type +% key of keys and a type 'a t of hash tables associating data of +% type 'a to keys of type key. The operations perform similarly +% to those of the generic interface, but use the hashing and +% equality functions specified in the functor argument H instead +% of generic equality and hashing. +% +% +%The polymorphic hash primitive +%============================== +% +%<< +% val hash : 'a -> int +%>> +% +% Hashtbl.hash x associates a positive integer to any value of +% any type. It is guaranteed that if x = y or Pervasives.compare +% x y = 0, then hash x = hash y. Moreover, hash always +% terminates, even on cyclic structures. +% +%<< +% val hash_param : int -> int -> 'a -> int +%>> +% +% Hashtbl.hash_param n m x computes a hash value for x, with the +% same properties as for hash. The two extra parameters n and m +% give more precise control over hashing. Hashing performs a +% depth-first, right-to-left traversal of the structure x, +% stopping after n meaningful nodes were encountered, or m nodes, +% meaningful or not, were encountered. Meaningful nodes are: +% integers; floating-point numbers; strings; characters; +% booleans; and constant constructors. Larger values of m and n +% means that more nodes are taken into account to compute the +% final hash value, and therefore collisions are less likely to +% happen. However, hashing takes longer. The parameters m and n +% govern the tradeoff between accuracy and speed. +% +% +% +%20.13 Module Int32 : 32'bit integers. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% This module provides operations on the type int32 of signed 32'bit integers. +%Unlike the built-in int type, the type int32 is guaranteed to be exactly +%32'bit wide on all platforms.

The bytes can then be read back later, possibly in another +%process, and decoded back into a data structure. The format for the byte +%sequences is compatible across all machines for a given version of Objective +%Caml. +% Warning: marshaling is currently not type-safe. The type of marshaled data +%is not transmitted along the value of the data, making it impossible to check +%that the data read back possesses the type expected by the context. In +%particular, the result type of the Marshal.from_* functions is given as 'a, +%but this is misleading: the returned Caml value does not possess type 'a for +%all 'a; it has one, unique type which cannot be determined at compile-type. +%The programmer should explicitly give the expected type of the returned value, +%using the following syntax: +% +% - (Marshal.from_channel chan : type). Anything can happen at run-time if the +% object in the file does not belong to the given type. +% +% The representation of marshaled values is not human-readable, and uses bytes +%that are not printable characters. Therefore, input and output channels used +%in conjunction with Marshal.to_channel and Marshal.from_channel must be opened +%in binary mode, using e.g. open_out_bin or open_in_bin; channels opened in +%text mode will cause unmarshaling errors on platforms where text channels +%behave differently than binary channels, e.g. Windows. +% 0.5cm +%<< +% type extern_flags = +% | No_sharing +%>> +% +% Don-t preserve sharing +% +%<< +% | Closures +%>> +% +% Send function closures +% +% The flags to the Marshal.to_* functions below. +% +%<< +% val to_channel : Pervasives.out_channel -> 'a -> extern_flags list -> unit +%>> +% +% Marshal.to_channel chan v flags writes the representation of v +% on channel chan. The flags argument is a possibly empty list of +% flags that governs the marshaling behavior with respect to +% sharing and functional values. +% If flags does not contain Marshal.No_sharing, circularities +% and sharing inside the value v are detected and preserved in +% the sequence of bytes produced. In particular, this guarantees +% that marshaling always terminates. Sharing between values +% marshaled by successive calls to Marshal.to_channel is not +% detected, though. If flags contains Marshal.No_sharing, sharing +% is ignored. This results in faster marshaling if v contains no +% shared substructures, but may cause slower marshaling and +% larger byte representations if v actually contains sharing, or +% even non-termination if v contains cycles. +% If flags does not contain Marshal.Closures, marshaling fails +% when it encounters a functional value inside v: only --pure-- +% data structures, containing neither functions nor objects, can +% safely be transmitted between different programs. If flags +% contains Marshal.Closures, functional values will be marshaled +% as a position in the code of the program. In this case, the +% output of marshaling can only be read back in processes that +% run exactly the same program, with exactly the same compiled +% code. (This is checked at un-marshaling time, using an MD5 +% digest of the code transmitted along with the code position.) +% +%<< +% val to_string : 'a -> extern_flags list -> string +%>> +% +% Marshal.to_string v flags returns a string containing the +% representation of v as a sequence of bytes.

Marshal.header_size[20.19] +% is the size, in characters, of the header. +% Marshal.data_size[20.19] buff ofs is the size, in characters, +% of the data part, assuming a valid header is stored in buff +% starting at position ofs. Finally, Marshal.total_size[20.19] +% buff ofs is the total size, in characters, of the marshaled +% value. Both Marshal.data_size[20.19] and +% Marshal.total_size[20.19] raise Failure if buff, ofs does not +% contain a valid header. +% To read the byte representation of a marshaled value into a +% string buffer, the program needs to read first +% Marshal.header_size[20.19] characters into the buffer, then +% determine the length of the remainder of the representation +% using Marshal.data_size[20.19], make sure the buffer is large +% enough to hold the remaining data, then read it, and finally +% call Marshal.from_string[20.19] to unmarshal the value. +% +%<< +% val data_size : string -> int -> int +%>> +% +% See Marshal.header_size[20.19]. +% +%<< +% val total_size : string -> int -> int +%>> +% +% See Marshal.header_size[20.19]. +% +% +% +%20.20 Module Nativeint : Processor-native integers. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% This module provides operations on the type nativeint of signed 32'bit +%integers (on 32'bit platforms) or signed 64'bit integers (on 64'bit +%platforms).

Moreover, calling Printexc.catch makes it +% harder to track the location of the exception using the +% debugger or the stack backtrace facility. So, do not use +% Printexc.catch in new code. +% +% +% +%20.24 Module Printf : Formatted output functions. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% 0.5cm +%<< +% val fprintf : +% Pervasives.out_channel -> +% ('a, Pervasives.out_channel, unit) Pervasives.format -> 'a +%>> +% +% fprintf outchan format arg1 ... argN formats the arguments +% arg1 to argN according to the format string format, and outputs +% the resulting string on the channel outchan. +% The format is a character string which contains two types of +% objects: plain characters, which are simply copied to the +% output channel, and conversion specifications, each of which +% causes conversion and printing of one argument. +% Conversion specifications consist in the % character, followed +% by optional flags and field widths, followed by one or two +% conversion character. The conversion characters and their +% meanings are: +% +% - d, i, n, or N: convert an integer argument to signed decimal. +% +% - u: convert an integer argument to unsigned decimal. +% - x: convert an integer argument to unsigned hexadecimal, +% using lowercase letters. +% - X: convert an integer argument to unsigned hexadecimal, +% using uppercase letters. +% - o: convert an integer argument to unsigned octal. +% - s: insert a string argument. +% - S: insert a string argument in Caml syntax (double quotes, +% escapes). +% - c: insert a character argument. +% - C: insert a character argument in Caml syntax (single quotes, +% escapes). +% - f: convert a floating-point argument to decimal notation, in +% the style dddd.ddd. +% - F: convert a floating-point argument in Caml syntax (dddd.ddd +% with a mandatory .). +% - e or E: convert a floating-point argument to decimal +% notation, in the style d.ddd e+-dd (mantissa and exponent). +% - g or G: convert a floating-point argument to decimal +% notation, in style f or e, E (whichever is more compact). +% - B: convert a boolean argument to the string true or false +% - b: convert a boolean argument (for backward compatibility; do +% not use in new programs). +% - ld, li, lu, lx, lX, lo: convert an int32 argument to the +% format specified by the second letter (decimal, hexadecimal, +% etc). +% - nd, ni, nu, nx, nX, no: convert a nativeint argument to the +% format specified by the second letter. +% - Ld, Li, Lu, Lx, LX, Lo: convert an int64 argument to the +% format specified by the second letter. +% - a: user-defined printer. Takes two arguments and apply the +% first one to outchan (the current output channel) and to the +% second argument. The first argument must therefore have type +% out_channel -> 'b -> unit and the second 'b. The output +% produced by the function is therefore inserted in the output +% of fprintf at the current point. +% - t: same as %a, but takes only one argument (with type +% out_channel -> unit) and apply it to outchan. +% - !: take no argument and flush the output. +% - %: take no argument and output one % character. +% +% The optional flags include: +% +% - -: left-justify the output (default is right justification). +% - 0: for numerical conversions, pad with zeroes instead of +% spaces. +% - +: for numerical conversions, prefix number with a + sign if +% positive. +% - space: for numerical conversions, prefix number with a space +% if positive. +% - `#': request an alternate formatting style for numbers. +% +% The field widths are composed of an optional integer literal +% indicating the minimal width of the result, possibly followed by +% a dot . and another integer literal indicating how many digits +% follow the decimal point in the %f, %e, and %E conversions. For +% instance, %6d prints an integer, prefixing it with spaces to +% fill at least 6 characters; and %.4f prints a float with 4 +% fractional digits. Each or both of the integer literals can also +% be specified as a *, in which case an extra integer argument is +% taken to specify the corresponding width or precision. +% Warning: if too few arguments are provided, for instance +% because the printf function is partially applied, the format is +% immediately printed up to the conversion of the first missing +% argument; printing will then resume when the missing arguments +% are provided. For example, List.iter (printf "x=%d y=%d " 1) +% [2;3] prints x=1 y=2 3 instead of the expected x=1 y=2 x=1 +% y=3. To get the expected behavior, do List.iter (fun y -> +% printf "x=%d y=%d " 1 y) [2;3]. +% +%<< +% val printf : ('a, Pervasives.out_channel, unit) Pervasives.format -> 'a +%>> +% +% Same as Printf.fprintf[20.24], but output on stdout. +% +%<< +% val eprintf : ('a, Pervasives.out_channel, unit) Pervasives.format -> 'a +%>> +% +% Same as Printf.fprintf[20.24], but output on stderr. +% +%<< +% val sprintf : ('a, unit, string) Pervasives.format -> 'a +%>> +% +% Same as Printf.fprintf[20.24], but instead of printing on an +% output channel, return a string containing the result of +% formatting the arguments. +% +%<< +% val bprintf : Buffer.t -> ('a, Buffer.t, unit) Pervasives.format -> 'a +%>> +% +% Same as Printf.fprintf[20.24], but instead of printing on an +% output channel, append the formatted arguments to the given +% extensible buffer (see module Buffer[20.3]). +% +%<< +% val kprintf : (string -> 'a) -> ('b, unit, string, 'a) format4 -> 'b +%>> +% +% kprintf k format arguments is the same as sprintf format +% arguments, except that the resulting string is passed as +% argument to k; the result of k is then returned as the result +% of kprintf. +% +% +% +%20.25 Module Queue : First-in first-out queues. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% This module implements queues (FIFOs), with in-place modification. +% 0.5cm +%<< +% type 'a t +%>> +% +% The type of queues containing elements of type 'a. +% +%<< +% exception Empty +%>> +% +% Raised when Queue.take[20.25] or Queue.peek[20.25] is applied +% to an empty queue. +% +%<< +% val create : unit -> 'a t +%>> +% +% Return a new queue, initially empty. +% +%<< +% val add : 'a -> 'a t -> unit +%>> +% +% add x q adds the element x at the end of the queue q. +% +%<< +% val push : 'a -> 'a t -> unit +%>> +% +% push is a synonym for add. +% +%<< +% val take : 'a t -> 'a +%>> +% +% take q removes and returns the first element in queue q, or +% raises Empty if the queue is empty. +% +%<< +% val pop : 'a t -> 'a +%>> +% +% pop is a synonym for take. +% +%<< +% val peek : 'a t -> 'a +%>> +% +% peek q returns the first element in queue q, without removing +% it from the queue, or raises Empty if the queue is empty. +% +%<< +% val top : 'a t -> 'a +%>> +% +% top is a synonym for peek. +% +%<< +% val clear : 'a t -> unit +%>> +% +% Discard all elements from a queue. +% +%<< +% val copy : 'a t -> 'a t +%>> +% +% Return a copy of the given queue. +% +%<< +% val is_empty : 'a t -> bool +%>> +% +% Return true if the given queue is empty, false otherwise. +% +%<< +% val length : 'a t -> int +%>> +% +% Return the number of elements in a queue. +% +%<< +% val iter : ('a -> unit) -> 'a t -> unit +%>> +% +% iter f q applies f in turn to all elements of q, from the +% least recently entered to the most recently entered. The queue +% itself is unchanged. +% +%<< +% val fold : ('a -> 'b -> 'a) -> 'a -> 'b t -> 'a +%>> +% +% fold f accu q is equivalent to List.fold_left f accu l, where +% l is the list of q-s elements. The queue remains unchanged. +% +%<< +% val transfer : 'a t -> 'a t -> unit +%>> +% +% transfer q1 q2 adds all of q1-s elements at the end of the +% queue q2, then clears q1. It is equivalent to the sequence iter +% (fun x -> add x q2) q1; clear q1, but runs in constant time. +% +% +% +%20.26 Module Random : Pseudo-random number generators (PRNG). +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% 0.5cm +% +%Basic functions +%=============== +% +%<< +% val init : int -> unit +%>> +% +% Initialize the generator, using the argument as a seed.

A scanning buffer is the +% argument passed to the scanning functions used by the scanf +% family of functions. The scanning buffer holds the current +% state of the scan, plus a function to get the next char from +% the input, and a token buffer to store the string matched so +% far. +% +% << +% val stdib : scanbuf +% >> +% +% The scanning buffer reading from stdin. stdib is equivalent +% to Scanning.from_channel stdin. +% +% << +% val from_string : string -> scanbuf +% >> +% +% Scanning.from_string s returns a scanning buffer which reads +% from the given string. Reading starts from the first +% character in the string. The end-of-input condition is set +% when the end of the string is reached. +% +% << +% val from_file : string -> scanbuf +% >> +% +% Bufferized file reading in text mode. The efficient and +% usual way to scan text mode files (in effect, from_file +% returns a buffer that reads characters in large chunks, +% rather than one character at a time as buffers returned by +% from_channel do). Scanning.from_file fname returns a +% scanning buffer which reads from the given file fname in +% text mode. +% +% << +% val from_file_bin : string -> scanbuf +% >> +% +% Bufferized file reading in binary mode. +% +% << +% val from_function : (unit -> char) -> scanbuf +% >> +% +% Scanning.from_function f returns a scanning buffer with the +% given function as its reading method. When scanning needs +% one more character, the given function is called. When the +% function has no more character to provide, it must signal an +% end-of-input condition by raising the exception End_of_file. +% +% << +% val from_channel : Pervasives.in_channel -> scanbuf +% >> +% +% Scanning.from_channel inchan returns a scanning buffer which +% reads one character at a time from the input channel inchan, +% starting at the current reading position. +% +% << +% val end_of_input : scanbuf -> bool +% >> +% +% Scanning.end_of_input scanbuf tests the end of input +% condition of the given buffer. +% +% << +% val beginning_of_input : scanbuf -> bool +% >> +% +% Scanning.beginning_of_input scanbuf tests the beginning of +% input condition of the given buffer. +% +% +% - end +% +% Scanning buffers. +% +%<< +% exception Scan_failure of string +%>> +% +% The exception that formatted input functions raise when the +% input cannot be read according to the given format. +% +%<< +% val bscanf : +% Scanning.scanbuf -> +% ('a, Scanning.scanbuf, 'b) Pervasives.format -> 'a -> 'b +%>> +% +% bscanf ib format f reads tokens from the scanning buffer ib +% according to the format string format, converts these tokens to +% values, and applies the function f to these values. The result +% of this application of f is the result of the whole construct. +% For instance, if p is the function fun s i -> i + 1, then +% Scanf.sscanf "x = 1" "%s = %i" p returns 2. +% Raise Scanf.Scan_failure if the given input does not match the +% format. +% Raise Failure if a conversion to a number is not possible. +% Raise End_of_file if the end of input is encountered while +% scanning and the input matches the given format so far. +% The format is a character string which contains three types of +% objects: +% +% - plain characters, which are simply matched with the +% characters of the input, +% - conversion specifications, each of which causes reading and +% conversion of one argument for f, +% - scanning indications to specify boundaries of tokens. +% +% Among plain characters the space character (ASCII code 32) has a +% special meaning: it matches --whitespace--, that is any number +% of tab, space, newline and carriage return characters. Hence, a +% space in the format matches any amount of whitespace in the +% input. +% Conversion specifications consist in the % character, followed +% by an optional flag, an optional field width, and followed by +% one or two conversion characters. The conversion characters and +% their meanings are: +% +% +% - d: reads an optionally signed decimal integer. +% - i: reads an optionally signed integer (usual input formats +% for hexadecimal (0x[d]+ and 0X[d]+), octal (0o[d]+), and +% binary 0b[d]+ notations are understood). +% - u: reads an unsigned decimal integer. +% - x or X: reads an unsigned hexadecimal integer. +% - o: reads an unsigned octal integer. +% - s: reads a string argument (by default strings end with a +% space). +% - S: reads a delimited string argument (delimiters and special +% escaped characters follow the lexical conventions of Caml). +% - c: reads a single character. To test the current input +% character without reading it, specify a null field width, +% i.e. use specification %0c. Raise Invalid_argument, if the +% field width specification is greater than 1. +% - C: reads a single delimited character (delimiters and special +% escaped characters follow the lexical conventions of Caml). +% - f, e, E, g, G: reads an optionally signed floating-point +% number in decimal notation, in the style dddd.ddd e/E+-dd. +% - F: reads a floating point number according to the lexical +% conventions of Caml (hence the decimal point is mandatory if +% the exponent part is not mentioned). +% - B: reads a boolean argument (true or false). +% - b: reads a boolean argument (for backward compatibility; do +% not use in new programs). +% - ld, li, lu, lx, lX, lo: reads an int32 argument to the +% format specified by the second letter (decimal, hexadecimal, +% etc). +% - nd, ni, nu, nx, nX, no: reads a nativeint argument to the +% format specified by the second letter. +% - Ld, Li, Lu, Lx, LX, Lo: reads an int64 argument to the +% format specified by the second letter. +% - [ range ]: reads characters that matches one of the +% characters mentioned in the range of characters range (or +% not mentioned in it, if the range starts with ^). Returns a +% string that can be empty, if no character in the input +% matches the range. Hence, [0-9] returns a string +% representing a decimal number or an empty string if no +% decimal digit is found. If a closing bracket appears in a +% range, it must occur as the first character of the range (or +% just after the ^ in case of range negation); hence []] +% matches a ] character and [^]] matches any character that is +% not ]. +% - l: applies f to the number of lines read so far. +% - n: applies f to the number of characters read so far. +% - N: applies f to the number of tokens read so far. +% - !: matches the end of input condition. +% - %: matches one % character in the input. +% +% Following the % character introducing a conversion, there may be +% the special flag _: the conversion that follows occurs as +% usual, but the resulting value is discarded. +% The field widths are composed of an optional integer literal +% indicating the maximal width of the token to read. For +% instance, %6d reads an integer, having at most 6 decimal digits; +% and %4f reads a float with at most 4 characters. +% Scanning indications appear just after the string conversions s +% and [ range ] to delimit the end of the token. A scanning +% indication is introduced by a @ character, followed by some +% constant character c. It means that the string token should end +% just before the next matching c (which is skipped). If no c +% character is encountered, the string token spreads as much as +% possible. For instance, "%s@\t" reads a string up to the next +% tabulation character. If a scanning indication @c does not +% follow a string conversion, it is ignored and treated as a plain +% c character. +% Notes: +% +% +% - the scanning indications introduce slight differences in the +% syntax of Scanf format strings compared to those used by the +% Printf module. However, scanning indications are similar to +% those of the Format module; hence, when producing formatted +% text to be scanned by !Scanf.bscanf, it is wise to use +% printing functions from Format (or, if you need to use +% functions from Printf, banish or carefully double check the +% format strings that contain -@- characters). +% +% +% - in addition to relevant digits, -_- characters may appear +% inside numbers (this is reminiscent to the usual Caml +% conventions). If stricter scanning is desired, use the range +% conversion facility instead of the number conversions. +% +% +% - the scanf facility is not intended for heavy duty lexical +% analysis and parsing. If it appears not expressive enough for +% your needs, several alternative exists: regular expressions +% (module Str), stream parsers, ocamllex-generated lexers, +% ocamlyacc-generated parsers. +% +%<< +% val fscanf : +% Pervasives.in_channel -> +% ('a, Scanning.scanbuf, 'b) Pervasives.format -> 'a -> 'b +%>> +% +% Same as Scanf.bscanf[20.27], but inputs from the given channel. +% Warning: since all scanning functions operate from a scanning +% buffer, be aware that each fscanf invocation must allocate a new +% fresh scanning buffer (unless careful use of partial evaluation +% in the program). Hence, there are chances that some characters +% seem to be skipped (in fact they are pending in the previously +% used buffer). This happens in particular when calling fscanf +% again after a scan involving a format that necessitates some +% look ahead (such as a format that ends by skipping whitespace +% in the input). +% To avoid confusion, consider using bscanf with an explicitly +% created scanning buffer. Use for instance Scanning.from_file f +% to allocate the scanning buffer reading from file f. +% This method is not only clearer it is also faster, since +% scanning buffers to files are optimized for fast bufferized +% reading. +% +%<< +% val sscanf : +% string -> ('a, Scanning.scanbuf, 'b) Pervasives.format -> 'a -> 'b +%>> +% +% Same as Scanf.bscanf[20.27], but inputs from the given string. +% +%<< +% val scanf : ('a, Scanning.scanbuf, 'b) Pervasives.format -> 'a -> 'b +%>> +% +% Same as Scanf.bscanf[20.27], but reads from the predefined +% scanning buffer Scanf.Scanning.stdib[20.27] that is connected +% to stdin. +% +%<< +% val kscanf : +% Scanning.scanbuf -> +% (Scanning.scanbuf -> exn -> 'a) -> +% ('b, Scanning.scanbuf, 'a) Pervasives.format -> 'b -> 'a +%>> +% +% Same as Scanf.bscanf[20.27], but takes an additional function +% argument ef that is called in case of error: if the scanning +% process or some conversion fails, the scanning function aborts +% and applies the error handling function ef to the scanning +% buffer and the exception that aborted the scanning process. +% +% +% +%20.28 Module Set : Sets over ordered types. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% This module implements the set data structure, given a total ordering +%function over the set elements. All operations over sets are purely +%applicative (no side-effects).

A weak +% pointer is a value that the garbage collector may erase at any +% time. A weak pointer is said to be full if it points to a +% value, empty if the value was erased by the GC. Note that weak +% arrays cannot be marshaled using Pervasives.output_value[19.2] +% or the functions of the Marshal[20.19] module. +% +%<< +% val create : int -> 'a t +%>> +% +% Weak.create n returns a new weak array of length n. All the +% pointers are initially empty. Raise Invalid_argument if n is +% negative or greater than Sys.max_array_length[20.34]-1. +% +%<< +% val length : 'a t -> int +%>> +% +% Weak.length ar returns the length (number of elements) of ar. +% +%<< +% val set : 'a t -> int -> 'a option -> unit +%>> +% +% Weak.set ar n (Some el) sets the nth cell of ar to be a (full) +% pointer to el; Weak.set ar n None sets the nth cell of ar to +% empty. Raise Invalid_argument "Weak.set" if n is not in the +% range 0 to Weak.length[20.35] a - 1. +% +%<< +% val get : 'a t -> int -> 'a option +%>> +% +% Weak.get ar n returns None if the nth cell of ar is empty, +% Some x (where x is the value) if it is full. Raise +% Invalid_argument "Weak.get" if n is not in the range 0 to +% Weak.length[20.35] a - 1. +% +%<< +% val get_copy : 'a t -> int -> 'a option +%>> +% +% Weak.get_copy ar n returns None if the nth cell of ar is +% empty, Some x (where x is a (shallow) copy of the value) if it +% is full. In addition to pitfalls with mutable values, the +% interesting difference with get is that get_copy does not +% prevent the incremental GC from erasing the value in its +% current cycle (get may delay the erasure to the next GC cycle). +% Raise Invalid_argument "Weak.get" if n is not in the range 0 +% to Weak.length[20.35] a - 1. +% +%<< +% val check : 'a t -> int -> bool +%>> +% +% Weak.check ar n returns true if the nth cell of ar is full, +% false if it is empty. Note that even if Weak.check ar n returns +% true, a subsequent Weak.get[20.35] ar n can return None. +% +%<< +% val fill : 'a t -> int -> int -> 'a option -> unit +%>> +% +% Weak.fill ar ofs len el sets to el all pointers of ar from ofs +% to ofs + len - 1. Raise Invalid_argument "Weak.fill" if ofs and +% len do not designate a valid subarray of a. +% +%<< +% val blit : 'a t -> int -> 'a t -> int -> int -> unit +%>> +% +% Weak.blit ar1 off1 ar2 off2 len copies len weak pointers from +% ar1 (starting at off1) to ar2 (starting at off2). It works +% correctly even if ar1 and ar2 are the same. Raise +% Invalid_argument "Weak.blit" if off1 and len do not designate a +% valid subarray of ar1, or if off2 and len do not designate a +% valid subarray of ar2. +% +% +%Weak hash tables +%================ +% +% A weak hash table is a hashed set of values. Each value may magically +%disappear from the set when it is not used by the rest of the program any +%more. This is normally used to share data structures without inducing memory +%leaks. Weak hash tables are defined on values from a Hashtbl.HashedType[20.12] +% module; the equal relation and hash function are taken from that module. We +%will say that v is an instance of x if equal x v is true. +% The equal relation must be able to work on a shallow copy of the values and +%give the same result as with the values themselves. +%<< +% module type S = >> +% +% sig +% +% +% << +% type data +% >> +% +% The type of the elements stored in the table. +% +% << +% type t +% >> +% +% The type of tables that contain elements of type data. Note +% that weak hash tables cannot be marshaled using +% Pervasives.output_value[19.2] or the functions of the +% Marshal[20.19] module. +% +% << +% val create : int -> t +% >> +% +% create n creates a new empty weak hash table, of initial +% size n. The table will grow as needed. +% +% << +% val clear : t -> unit +% >> +% +% Remove all elements from the table. +% +% << +% val merge : t -> data -> data +% >> +% +% merge t x returns an instance of x found in t if any, or +% else adds x to t and return x. +% +% << +% val add : t -> data -> unit +% >> +% +% add t x adds x to t. If there is already an instance of x +% in t, it is unspecified which one will be returned by +% subsequent calls to find and merge. +% +% << +% val remove : t -> data -> unit +% >> +% +% remove t x removes from t one instance of x. Does nothing +% if there is no instance of x in t. +% +% << +% val find : t -> data -> data +% >> +% +% find t x returns an instance of x found in t. Raise +% Not_found if there is no such element. +% +% << +% val find_all : t -> data -> data list +% >> +% +% find_all t x returns a list of all the instances of x found +% in t. +% +% << +% val mem : t -> data -> bool +% >> +% +% mem t x returns true if there is at least one instance of x +% in t, false otherwise. +% +% << +% val iter : (data -> unit) -> t -> unit +% >> +% +% iter f t calls f on each element of t, in some unspecified +% order. It is not specified what happens if f tries to change +% t itself. +% +% << +% val fold : (data -> 'a -> 'a) -> t -> 'a -> 'a +% >> +% +% fold f t init computes (f d1 (... (f dN init))) where d1 +% ... dN are the elements of t in some unspecified order. It +% is not specified what happens if f tries to change t itself. +% +% << +% val count : t -> int +% >> +% +% Count the number of elements in the table. count t gives the +% same result as fold (fun _ n -> n+1) t 0 but does not delay +% the deallocation of the dead elements. +% +% << +% val stats : t -> int * int * int * int * int * int +% >> +% +% Return statistics on the table. The numbers are, in order: +% table length, number of entries, sum of bucket lengths, +% smallest bucket length, median bucket length, biggest bucket +% length. +% +% +% - end +% +% The output signature of the functor Weak.Make[20.35]. +% +%<< +% module Make : >> +% +% functor (H : Hashtbl.HashedType) -> S with type data = H.t +% Functor building an implementation of the weak hash table +% structure. +% +% +% +% +%Chapter 21 The unix library: Unix system calls +%************************************************* +% +% The unix library makes many Unix system calls and system-related library +%functions available to Objective Caml programs. This chapter describes briefly +%the functions provided. Refer to sections 2 and 3 of the Unix manual for more +%details on the behavior of these functions. +% Not all functions are provided by all Unix variants. If some functions are +%not available, they will raise Invalid_arg when called. +% Programs that use the unix library must be linked as follows: +%<< +% ocamlc other options unix.cma other files +% ocamlopt other options unix.cmxa other files +%>> +% For interactive use of the unix library, do: +%<< +% ocamlmktop -o mytop unix.cma +% ./mytop +%>> +% or (if dynamic linking of C libraries is supported on your platform), start +%ocaml and type #load "unix.cma";;. +% Windows: +% A fairly complete emulation of the Unix system calls is +% provided in the Windows version of Objective Caml.

Data written to the returned +% output channel is sent to the standard input of the command. +% Warning: writes on output channels are buffered, hence be +% careful to call Pervasives.flush[19.2] at the right times to +% ensure correct synchronization. +% +%<< +% val open_process : string -> Pervasives.in_channel * Pervasives.out_channel +%>> +% +% Same as Unix.open_process_out[21.1], but redirects both the +% standard input and standard output of the command to pipes +% connected to the two returned channels. The input channel is +% connected to the output of the command, and the output channel +% to the input of the command. +% +%<< +% val open_process_full : +% string -> +% string array -> +% Pervasives.in_channel * Pervasives.out_channel * Pervasives.in_channel +%>> +% +% Similar to Unix.open_process[21.1], but the second argument +% specifies the environment passed to the command. The result is +% a triple of channels connected respectively to the standard +% output, standard input, and standard error of the command. +% +%<< +% val close_process_in : Pervasives.in_channel -> process_status +%>> +% +% Close channels opened by Unix.open_process_in[21.1], wait for +% the associated command to terminate, and return its termination +% status. +% +%<< +% val close_process_out : Pervasives.out_channel -> process_status +%>> +% +% Close channels opened by Unix.open_process_out[21.1], wait +% for the associated command to terminate, and return its +% termination status. +% +%<< +% val close_process : +% Pervasives.in_channel * Pervasives.out_channel -> process_status +%>> +% +% Close channels opened by Unix.open_process[21.1], wait for +% the associated command to terminate, and return its termination +% status. +% +%<< +% val close_process_full : +% Pervasives.in_channel * Pervasives.out_channel * Pervasives.in_channel -> +% process_status +%>> +% +% Close channels opened by Unix.open_process_full[21.1], wait +% for the associated command to terminate, and return its +% termination status. +% +% +%Symbolic links +%============== +% +%<< +% val symlink : string -> string -> unit +%>> +% +% symlink source dest creates the file dest as a symbolic link +% to the file source. +% +%<< +% val readlink : string -> string +%>> +% +% Read the contents of a link. +% +% +%Polling +%======= +% +%<< +% val select : +% file_descr list -> +% file_descr list -> +% file_descr list -> +% float -> file_descr list * file_descr list * file_descr list +%>> +% +% Wait until some input/output operations become possible on +% some channels. The three list arguments are, respectively, a set +% of descriptors to check for reading (first argument), for +% writing (second argument), or for exceptional conditions (third +% argument). The fourth argument is the maximal timeout, in +% seconds; a negative fourth argument means no timeout (unbounded +% wait). The result is composed of three sets of descriptors: +% those ready for reading (first component), ready for writing +% (second component), and over which an exceptional condition is +% pending (third component). +% +% +%Locking +%======= +% +%<< +% type lock_command = +% | F_ULOCK +%>> +% +% Unlock a region +% +%<< +% | F_LOCK +%>> +% +% Lock a region for writing, and block if already locked +% +%<< +% | F_TLOCK +%>> +% +% Lock a region for writing, or fail if already locked +% +%<< +% | F_TEST +%>> +% +% Test a region for other process locks +% +%<< +% | F_RLOCK +%>> +% +% Lock a region for reading, and block if already locked +% +%<< +% | F_TRLOCK +%>> +% +% Lock a region for reading, or fail if already locked +% +% Commands for Unix.lockf[21.1]. +% +%<< +% val lockf : file_descr -> lock_command -> int -> unit +%>> +% +% lockf fd cmd size puts a lock on a region of the file opened +% as fd. The region starts at the current read/write position for +% fd (as set by Unix.lseek[21.1]), and extends size bytes forward +% if size is positive, size bytes backwards if size is negative, +% or to the end of the file if size is zero. A write lock +% prevents any other process from acquiring a read or write lock +% on the region. A read lock prevents any other process from +% acquiring a write lock on the region, but lets other processes +% acquire read locks on it. +% The F_LOCK and F_TLOCK commands attempts to put a write lock on +% the specified region. The F_RLOCK and F_TRLOCK commands +% attempts to put a read lock on the specified region. If one or +% several locks put by another process prevent the current process +% from acquiring the lock, F_LOCK and F_RLOCK block until these +% locks are removed, while F_TLOCK and F_TRLOCK fail immediately +% with an exception. The F_ULOCK removes whatever locks the +% current process has on the specified region. Finally, the +% F_TEST command tests whether a write lock can be acquired on +% the specified region, without actually putting a lock. It +% returns immediately if successful, or fails otherwise. +% +% +%Signals +%======= +% +% Note: installation of signal handlers is performed via the functions +%Sys.signal[20.34] and Sys.set_signal[20.34]. +%<< +% val kill : int -> int -> unit +%>> +% +% kill pid sig sends signal number sig to the process with id +% pid. +% +%<< +% type sigprocmask_command = +% | SIG_SETMASK +% | SIG_BLOCK +% | SIG_UNBLOCK +%>> +% +%<< +% val sigprocmask : sigprocmask_command -> int list -> int list +%>> +% +% sigprocmask cmd sigs changes the set of blocked signals. If +% cmd is SIG_SETMASK, blocked signals are set to those in the +% list sigs. If cmd is SIG_BLOCK, the signals in sigs are added +% to the set of blocked signals. If cmd is SIG_UNBLOCK, the +% signals in sigs are removed from the set of blocked signals. +% sigprocmask returns the set of previously blocked signals. +% +%<< +% val sigpending : unit -> int list +%>> +% +% Return the set of blocked signals that are currently pending. +% +%<< +% val sigsuspend : int list -> unit +%>> +% +% sigsuspend sigs atomically sets the blocked signals to sigs +% and waits for a non-ignored, non'blocked signal to be delivered. +% On return, the blocked signals are reset to their initial +% value. +% +%<< +% val pause : unit -> unit +%>> +% +% Wait until a non-ignored, non'blocked signal is delivered. +% +% +%Time functions +%============== +% +%<< +% type process_times = { +% tms_utime : float ; +%>> +% +% User time for the process +% +%<< +% tms_stime : float ; +%>> +% +% System time for the process +% +%<< +% tms_cutime : float ; +%>> +% +% User time for the children processes +% +%<< +% tms_cstime : float ; +%>> +% +% System time for the children processes +% +%<< +% } +%>> +% +% The execution times (CPU times) of a process. +% +%<< +% type tm = { +% tm_sec : int ; +%>> +% +% Seconds 0..60 +% +%<< +% tm_min : int ; +%>> +% +% Minutes 0..59 +% +%<< +% tm_hour : int ; +%>> +% +% Hours 0..23 +% +%<< +% tm_mday : int ; +%>> +% +% Day of month 1..31 +% +%<< +% tm_mon : int ; +%>> +% +% Month of year 0..11 +% +%<< +% tm_year : int ; +%>> +% +% Year - 1900 +% +%<< +% tm_wday : int ; +%>> +% +% Day of week (Sunday is 0) +% +%<< +% tm_yday : int ; +%>> +% +% Day of year 0..365 +% +%<< +% tm_isdst : bool ; +%>> +% +% Daylight time savings in effect +% +%<< +% } +%>> +% +% The type representing wallclock time and calendar date. +% +%<< +% val time : unit -> float +%>> +% +% Return the current time since 00:00:00 GMT, Jan. 1, 1970, in +% seconds. +% +%<< +% val gettimeofday : unit -> float +%>> +% +% Same as Unix.time[21.1], but with resolution better than 1 +% second. +% +%<< +% val gmtime : float -> tm +%>> +% +% Convert a time in seconds, as returned by Unix.time[21.1], into +% a date and a time. Assumes UTC (Coordinated Universal Time), +% also known as GMT. +% +%<< +% val localtime : float -> tm +%>> +% +% Convert a time in seconds, as returned by Unix.time[21.1], into +% a date and a time. Assumes the local time zone. +% +%<< +% val mktime : tm -> float * tm +%>> +% +% Convert a date and time, specified by the tm argument, into a +% time in seconds, as returned by Unix.time[21.1]. The tm_isdst, +% tm_wday and tm_yday fields of tm are ignored. Also return a +% normalized copy of the given tm record, with the tm_wday, +% tm_yday, and tm_isdst fields recomputed from the other fields, +% and the other fields normalized (so that, e.g., 40 October is +% changed into 9 November). The tm argument is interpreted in the +% local time zone. +% +%<< +% val alarm : int -> int +%>> +% +% Schedule a SIGALRM signal after the given number of seconds. +% +%<< +% val sleep : int -> unit +%>> +% +% Stop execution for the given number of seconds. +% +%<< +% val times : unit -> process_times +%>> +% +% Return the execution times of the process. +% +%<< +% val utimes : string -> float -> float -> unit +%>> +% +% Set the last access time (second arg) and last modification +% time (third arg) for a file.

The s argument is interpreted as follows: +% s.it_value, if nonzero, is the time to the next timer +% expiration; s.it_interval, if nonzero, specifies a value to be +% used in reloading it_value when the timer expires. Setting +% s.it_value to zero disable the timer. Setting s.it_interval to +% zero causes the timer to be disabled after its next expiration. +% +% +%User id, group id +%================= +% +%<< +% val getuid : unit -> int +%>> +% +% Return the user id of the user executing the process. +% +%<< +% val geteuid : unit -> int +%>> +% +% Return the effective user id under which the process runs. +% +%<< +% val setuid : int -> unit +%>> +% +% Set the real user id and effective user id for the process. +% +%<< +% val getgid : unit -> int +%>> +% +% Return the group id of the user executing the process. +% +%<< +% val getegid : unit -> int +%>> +% +% Return the effective group id under which the process runs. +% +%<< +% val setgid : int -> unit +%>> +% +% Set the real group id and effective group id for the process. +% +%<< +% val getgroups : unit -> int array +%>> +% +% Return the list of groups to which the user executing the +% process belongs. +% +%<< +% type passwd_entry = { +% pw_name : string ; +% pw_passwd : string ; +% pw_uid : int ; +% pw_gid : int ; +% pw_gecos : string ; +% pw_dir : string ; +% pw_shell : string ; +% } +%>> +% +% Structure of entries in the passwd database. +% +%<< +% type group_entry = { +% gr_name : string ; +% gr_passwd : string ; +% gr_gid : int ; +% gr_mem : string array ; +% } +%>> +% +% Structure of entries in the groups database. +% +%<< +% val getlogin : unit -> string +%>> +% +% Return the login name of the user executing the process. +% +%<< +% val getpwnam : string -> passwd_entry +%>> +% +% Find an entry in passwd with the given name, or raise +% Not_found. +% +%<< +% val getgrnam : string -> group_entry +%>> +% +% Find an entry in group with the given name, or raise +% Not_found. +% +%<< +% val getpwuid : int -> passwd_entry +%>> +% +% Find an entry in passwd with the given user id, or raise +% Not_found. +% +%<< +% val getgrgid : int -> group_entry +%>> +% +% Find an entry in group with the given group id, or raise +% Not_found. +% +% +%Internet addresses +%================== +% +%<< +% type inet_addr +%>> +% +% The abstract type of Internet addresses. +% +%<< +% val inet_addr_of_string : string -> inet_addr +%>> +% +% Conversion from the printable representation of an Internet +% address to its internal representation.

To include +% a ] character in a set, make it the first character of the +% set. To include a - character in a set, make it the first or +% the last character of the set. +% - ^ Matches at beginning of line (either at the beginning of +% the matched string, or just after a newline character). +% - $ Matches at end of line (either at the end of the matched +% string, or just before a newline character). +% - \| (infix) Alternative between two expressions. +% - \(..\) Grouping and naming of the enclosed expression. +% - \1 The text matched by the first \(...\) expression (\2 for +% the second expression, and so on up to \9). +% - \b Matches word boundaries. +% - \ Quotes special characters.

The user must make sure that the +% parameter s is the same string that was passed to the matching +% or searching function. matched_group n s raises Not_found if +% the nth group of the regular expression was not matched. This +% can happen with groups inside alternatives \|, options ? or +% repetitions *. For instance, the empty string will match +% \(a\)*, but matched_group 1 "" will raise Not_found because the +% first group itself was not matched. +% +%<< +% val group_beginning : int -> int +%>> +% +% group_beginning n returns the position of the first character +% of the substring that was matched by the nth group of the +% regular expression. +% Raises +% +% - Not_found if the nth group of the regular expression was not +% matched. +% - Invalid_argument if there are fewer than n groups in the +% regular expression. +% +%<< +% val group_end : int -> int +%>> +% +% group_end n returns the position of the character following +% the last character of substring that was matched by the nth +% group of the regular expression. +% Raises +% +% - Not_found if the nth group of the regular expression was not +% matched. +% - Invalid_argument if there are fewer than n groups in the +% regular expression. +% +% +%Replacement +%=========== +% +%<< +% val global_replace : regexp -> string -> string -> string +%>> +% +% global_replace regexp templ s returns a string identical to s, +% except that all substrings of s that match regexp have been +% replaced by templ. The replacement template templ can contain +% \1, \2, etc; these sequences will be replaced by the text +% matched by the corresponding group in the regular expression. +% \0 stands for the text matched by the whole regular expression. +% +%<< +% val replace_first : regexp -> string -> string -> string +%>> +% +% Same as Str.global_replace[23.1], except that only the first +% substring matching the regular expression is replaced. +% +%<< +% val global_substitute : regexp -> (string -> string) -> string -> string +%>> +% +% global_substitute regexp subst s returns a string identical to +% s, except that all substrings of s that match regexp have been +% replaced by the result of function subst. The function subst is +% called once for each matching substring, and receives s (the +% whole text) as argument. +% +%<< +% val substitute_first : regexp -> (string -> string) -> string -> string +%>> +% +% Same as Str.global_substitute[23.1], except that only the first +% substring matching the regular expression is replaced. +% +%<< +% val replace_matched : string -> string -> string +%>> +% +% replace_matched repl s returns the replacement text repl in +% which \1, \2, etc. have been replaced by the text matched by +% the corresponding groups in the most recent matching operation. +% s must be the same string that was matched during this matching +% operation. +% +% +%Splitting +%========= +% +%<< +% val split : regexp -> string -> string list +%>> +% +% split r s splits s into substrings, taking as delimiters the +% substrings that match r, and returns the list of substrings. +% For instance, split (regexp "[ \t]+") s splits s into +% blank-separated words. An occurrence of the delimiter at the +% beginning and at the end of the string is ignored. +% +%<< +% val bounded_split : regexp -> string -> int -> string list +%>> +% +% Same as Str.split[23.1], but splits into at most n substrings, +% where n is the extra integer parameter. +% +%<< +% val split_delim : regexp -> string -> string list +%>> +% +% Same as Str.split[23.1] but occurrences of the delimiter at +% the beginning and at the end of the string are recognized and +% returned as empty strings in the result. For instance, +% split_delim (regexp " ") " abc " returns [""; "abc"; ""], while +% split with the same arguments returns ["abc"]. +% +%<< +% val bounded_split_delim : regexp -> string -> int -> string list +%>> +% +% Same as Str.bounded_split[23.1], but occurrences of the +% delimiter at the beginning and at the end of the string are +% recognized and returned as empty strings in the result. +% +%<< +% type split_result = +% | Text of string +% | Delim of string +%>> +% +%<< +% val full_split : regexp -> string -> split_result list +%>> +% +% Same as Str.split_delim[23.1], but returns the delimiters as +% well as the substrings contained between delimiters. The former +% are tagged Delim in the result list; the latter are tagged +% Text. For instance, full_split (regexp "[{}]") "{ab}" returns +% [Delim "{"; Text "ab"; Delim "}"]. +% +%<< +% val bounded_full_split : regexp -> string -> int -> split_result list +%>> +% +% Same as Str.bounded_split_delim[23.1], but returns the +% delimiters as well as the substrings contained between +% delimiters. The former are tagged Delim in the result list; the +% latter are tagged Text. +% +% +%Extracting substrings +%===================== +% +%<< +% val string_before : string -> int -> string +%>> +% +% string_before s n returns the substring of all characters of s +% that precede position n (excluding the character at position +% n). +% +%<< +% val string_after : string -> int -> string +%>> +% +% string_after s n returns the substring of all characters of s +% that follow position n (including the character at position n). +% +%<< +% val first_chars : string -> int -> string +%>> +% +% first_chars s n returns the first n characters of s. This is +% the same function as Str.string_before[23.1]. +% +%<< +% val last_chars : string -> int -> string +%>> +% +% last_chars s n returns the last n characters of s. +% +% +% +% +% +%dChapter 24 The threads library +%d********************************* +% +% The threads library allows concurrent programming in Objective Caml. It +%provides multiple threads of control (also called lightweight processes) that +%execute concurrently in the same memory space. Threads communicate by in-place +%modification of shared data structures, or by sending and receiving data on +%communication channels. +% The threads library is implemented by time-sharing on a single processor. It +%will not take advantage of multi-processor machines. Using this library will +%therefore never make programs run faster. However, many programs are easier to +%write when structured as several communicating processes. +% Two implementations of the threads library are available, depending on the +%capabilities of the operating system: +% +% - System threads. This implementation builds on the OS-provided threads +% facilities: POSIX 1003.1c threads for Unix, and Win32 threads for Windows. +% When available, system threads support both bytecode and native'code +% programs. +% - VM-level threads. This implementation performs time-sharing and context +% switching at the level of the OCaml virtual machine (bytecode interpreter). +% It is available on Unix systems, and supports only bytecode programs. It +% cannot be used with native'code programs. +% Programs that use system threads must be linked as follows: +%<< +% ocamlc -thread other options threads.cma other files +% ocamlopt -thread other options threads.cmxa other files +%>> +% All object files on the command line must also have been compiled with the +%-thread option (see chapter 8). +% Programs that use VM-level threads must be compiled with the -vmthread option +%to ocamlc (see chapter 8), and be linked as follows: +%<< +% ocamlc -vmthread other options threads.cma other files +%>> +% +% +% +%d24.1 Module Thread : Lightweight threads for Posix 1003.1c and Win32. +%d*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +%d% +%d% +%d% 0.5cm +%d%<< +%d type t +%d%>> +%d% +%d% The type of thread handles. +%d% +%d% +%d%Thread creation and termination +%d%=============================== +%d% +%d%<< +%d val create : ('a -> 'b) -> 'a -> t +%d%>> +% +% Thread.create funct arg creates a new thread of control, in +% which the function application funct arg is executed +% concurrently with the other threads of the program. The +% application of Thread.create returns the handle of the newly +% created thread. The new thread terminates when the application +% funct arg returns, either normally or by raising an uncaught +% exception. In the latter case, the exception is printed on +% standard error, but not propagated back to the parent thread. +% Similarly, the result of the application funct arg is discarded +% and not directly accessible to the parent thread. +% +%<< +% val self : unit -> t +%>> +% +% Return the thread currently executing. +% +%<< +% val id : t -> int +%>> +% +% Return the identifier of the given thread.

The two components are separated by a space. +% Either can be omitted, or both. Examples: +% +% open_graph "foo:0" connects to the display foo:0 and creates a +% window with the default geometry +% open_graph "foo:0 300x100+50-0" connects to the display foo:0 +% and creates a window 300 pixels wide by 100 pixels tall, at +% location (50,0) +% open_graph " 300x100+50-0" connects to the default display and +% creates a window 300 pixels wide by 100 pixels tall, at +% location (50,0) +% open_graph "" connects to the default display and creates a +% window with the default geometry. +% +% +% Windows: +% This library is available both for standalone compiled programs +% and under the toplevel application ocamlwin.exe.

NDBM databases +%maintain key/data associations, where both the key and the data are arbitrary +%strings. They support fairly large databases (several gigabytes) and can +%retrieve a keyed item in one or two file system accesses. Refer to the Unix +%manual pages for more information. +% Unix: +% Programs that use the dbm library must be linked as follows: +% << +% ocamlc other options dbm.cma other files +% ocamlopt other options dbm.cmxa other files +% >> +% For interactive use of the dbm library, do: +% << +% ocamlmktop -o mytop dbm.cma +% ./mytop +% >> +% +% or (if dynamic linking of C libraries is supported on your platform), start +%ocaml and type #load "dbm.cma";;. +% Windows: +% This library is not available. +% +% +% +%26.1 Module Dbm : Interface to the NDBM database. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% 0.5cm +%<< +% type t +%>> +% +% The type of file descriptors opened on NDBM databases. +% +%<< +% type open_flag = +% | Dbm_rdonly +% | Dbm_wronly +% | Dbm_rdwr +% | Dbm_create +%>> +% +% Flags for opening a database (see Dbm.opendbm[26.1]). +% +%<< +% exception Dbm_error of string +%>> +% +% Raised by the following functions when an error is encountered. +% +%<< +% val opendbm : string -> open_flag list -> int -> t +%>> +% +% Open a descriptor on an NDBM database.

Type +%safety is ensured by limiting the set of modules from the running program that +%the loaded object file can access, and checking that the running program and +%the loaded object file have been compiled against the same interfaces for these +%modules. +% Programs that use the dynlink library simply need to link dynlink.cma with +%their object files and other libraries. Dynamic linking is available only to +%bytecode programs compiled with ocamlc, not to native'code programs compiled +%with ocamlopt. +% +% +%27.1 Module Dynlink : Dynamic loading of bytecode object files. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= +% +% +% 0.5cm +% +%Initialization +%============== +% +%<< +% val init : unit -> unit +%>> +% +% Initialize the Dynlink library.

No facilities are provided to access value names +% defined by the unit. Therefore, the unit must register itself +% its entry points with the main program, e.g. by modifying +% tables of functions. +% +%<< +% val loadfile_private : string -> unit +%>> +% +% Same as loadfile, except that the compilation units just loaded +% are hidden (cannot be referenced) from other modules +% dynamically loaded afterwards. +% +% +%Access control +%============== +% +%<< +% val allow_only : string list -> unit +%>> +% +% allow_only units restricts the compilation units that +% dynamically-linked units can reference: it only allows +% references to the units named in list units. References to any +% other compilation unit will cause a Unavailable_unit error +% during loadfile or loadfile_private. +% Initially (just after calling init), all compilation units +% composing the program currently running are available for +% reference from dynamically-linked units. allow_only can be used +% to grant access to some of them only, e.g. to the units that +% compose the API for dynamically-linked code, and prevent access +% to all other units, e.g. private, internal modules of the +% running program. +% +%<< +% val prohibit : string list -> unit +%>> +% +% prohibit units prohibits dynamically-linked units from +% referencing the units named in list units. This can be used to +% prevent access to selected units, e.g. private, internal +% modules of the running program. +% +%<< +% val default_available_units : unit -> unit +%>> +% +% Reset the set of units that can be referenced from +% dynamically-linked code to its default value, that is, all +% units composing the currently running program. +% +%<< +% val allow_unsafe_modules : bool -> unit +%>> +% +% Govern whether unsafe object files are allowed to be +% dynamically linked. A compilation unit is --unsafe-- if it +% contains declarations of external functions, which can break +% type safety. By default, dynamic linking of unsafe object files +% is not allowed. +% +% +%Deprecated, low-level API for access control +%============================================ +% +%<< +% val add_interfaces : string list -> string list -> unit +%>> +% +% add_interfaces units path grants dynamically-linked object +% files access to the compilation units named in list units.

This interface is generated in an automated way, and you should refer +%to Tcl/Tk books and man pages for detailed information on the behavior of the +%numerous functions. We also suggest to use ocamlbrowser to see the types of the +%various functions, that are the best documentation for the library itself. +% +% Programs that use the labltk library must be linked as follows: +%<< +% ocamlc other options -I +labltk labltk.cma other files +% ocamlopt other options -I +labltk labltk.cmxa other files +%>> +% +% Unix: +% The labltk library is available for any system with Tcl/Tk +% installed, starting from Tcl 7.5/Tk 4.1 up to Tcl/Tk 8.3. Beware +% that some beta versions may have compatibility problems. +% If the library was not compiled correctly, try to run again the +% configure script with the option -tkdefs switches, where +% switches is a list of C-style inclusion paths leading to the +% right tcl.h and tk.h, for instance --I/usr/local/include/tcl8.3 +% -I/usr/local/include/tk8.3-. +% A script is installed, to make easier the use of the labltk +% library as toplevel. +% +% labltk This is a toplevel including the labltk library, and +% the path is already set as to allow the use of the various +% modules. It also includes code for the Unix and Str +% libraries. You can use it in place of ocaml. +% +% +% Windows: +% The labltk library has been precompiled for use with Tcl/Tk +% 8.3. You must first have it installed on your system. It can be +% downloaded from +% http://www.scriptics.com/products/tcltk/8.3.html. After +% installing it, you must put the dynamically loaded libraries +% tcl83.dll and tk83.dll (from the bin directory of the Tcl +% installation) in a directory included in you path. +% No toplevel is available, but you can load the library from the +% standard toplevel with the following commands. +% +% << +% # #directory "+labltk";; +% # #load "labltk.cma";; +% >> +% You can also load it directly from the command line. +% +% << +% C:\ocaml\bin> ocaml -I +labltk labltk.cma +% >> +% +% +% The labltk library is composed of a large number of modules. +% +% << +% Bell Imagebitmap Place +% Button Imagephoto Radiobutton +% Canvas Label Scale +% Checkbutton Listbox Scrollbar +% Clipboard Menu Selection +% Dialog Menubutton Text +% Entry Message Tk +% Focus Option Tkwait +% Frame Optionmenu Toplevel +% Grab Pack Winfo +% Grid Palette Wm +% >> +% +% Giving a detailed account of each of these module would be impractical here. +%We will just present some of the basic functions in the module Tk.

The main differences between -'big +%arrays-- and standard Caml arrays are as follows: +% +% - Big arrays are not limited in size, unlike Caml arrays (float array are +% limited to 2097151 elements on a 32'bit platform, other array types to +% 4194303 elements). +% - Big arrays are multi-dimensional. Any number of dimensions between 1 and 16 +% is supported. In contrast, Caml arrays are mono-dimensional and require +% encoding multi-dimensional arrays as arrays of arrays. +% - Big arrays can only contain integers and floating-point numbers, while Caml +% arrays can contain arbitrary Caml data types. However, big arrays provide +% more space-efficient storage of integer and floating-point elements, in +% particular because they support --small-- types such as single-precision +% floats and 8 and 16'bit integers, in addition to the standard Caml types of +% double-precision floats and 32 and 64'bit integers. +% - The memory layout of big arrays is entirely compatible with that of arrays +% in C and Fortran, allowing large arrays to be passed back and forth between +% Caml code and C / Fortran code with no data copying at all. +% - Big arrays support interesting high-level operations that normal arrays do +% not provide efficiently, such as extracting sub'arrays and --slicing-- a +% multi-dimensional array along certain dimensions, all without any copying. +% Programs that use the bigarray library must be linked as follows: +%<< +% ocamlc other options bigarray.cma other files +% ocamlopt other options bigarray.cmxa other files +%>> +% For interactive use of the bigarray library, do: +%<< +% ocamlmktop -o mytop bigarray.cma +% ./mytop +%>> +% or (if dynamic linking of C libraries is supported on your platform), start +%ocaml and type #load "bigarray.cma";;. +% +% +%29.1 Module Bigarray : Large, multi-dimensional, numerical arrays. +%*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* +% +% +% This module implements multi-dimensional arrays of integers and +%floating-point numbers, thereafter referred to as -'big arrays--.

Any number of dimensions between 1 and +% 16 is supported. +% The three type parameters to Genarray.t identify the array +% element kind and layout, as follows: +% +% - the first parameter, 'a, is the Caml type for accessing +% array elements (float, int, int32, int64, nativeint); +% - the second parameter, 'b, is the actual kind of array +% elements (float32_elt, float64_elt, int8_signed_elt, +% int8_unsigned_elt, etc); +% - the third parameter, 'c, identifies the array layout +% (c_layout or fortran_layout). +% +% For instance, (float, float32_elt, fortran_layout) Genarray.t +% is the type of generic big arrays containing 32'bit floats +% in Fortran layout; reads and writes in this array use the +% Caml type float. +% +% << +% val create : +% ('a, 'b) Bigarray.kind -> +% 'c Bigarray.layout -> int array -> ('a, 'b, 'c) t +% >> +% +% Genarray.create kind layout dimensions returns a new big +% array whose element kind is determined by the parameter kind +% (one of float32, float64, int8_signed, etc) and whose layout +% is determined by the parameter layout (one of c_layout or +% fortran_layout). The dimensions parameter is an array of +% integers that indicate the size of the big array in each +% dimension. The length of dimensions determines the number of +% dimensions of the bigarray. +% For instance, Genarray.create int32 c_layout [|4;6;8|] +% returns a fresh big array of 32'bit integers, in C layout, +% having three dimensions, the three dimensions being 4, 6 and +% 8 respectively. +% Big arrays returned by Genarray.create are not initialized: +% the initial values of array elements is unspecified. +% Genarray.create raises Invalid_arg if the number of +% dimensions is not in the range 1 to 16 inclusive, or if one +% of the dimensions is negative. +% +% << +% val num_dims : ('a, 'b, 'c) t -> int +% >> +% +% Return the number of dimensions of the given big array. +% +% << +% val dims : ('a, 'b, 'c) t -> int array +% >> +% +% Genarray.dims a returns all dimensions of the big array a, +% as an array of integers of length Genarray.num_dims a. +% +% << +% val nth_dim : ('a, 'b, 'c) t -> int -> int +% >> +% +% Genarray.nth_dim a n returns the n-th dimension of the big +% array a.

It +%declares the functions, constants and macros discussed below. +% +% +%29.2.2 Accessing a Caml bigarray from C or Fortran +%=================================================== +% +% If v is a Caml value representing a big array, the expression +%Data_bigarray_val(v) returns a pointer to the data part of the array. This +%pointer is of type void * and can be cast to the appropriate C type for the +%array (e.g. double [], char [][10], etc). +% Various characteristics of the Caml big array can be consulted from C as +%follows: +% +% -------------------------------------------------------------------- +% | C expression | Returns | +% -------------------------------------------------------------------- +% |Bigarray_val(v)->num_dims |number of dimensions | +% |Bigarray_val(v)->dim[i] |i-th dimension | +% |Bigarray_val(v)->flags & BIGARRAY_KIND_MASK|kind of array elements| +% -------------------------------------------------------------------- +% The kind of array elements is one of the following constants: +% +% -------------------------------------------------------------- +% | Constant | Element kind | +% -------------------------------------------------------------- +% |BIGARRAY_FLOAT32 |32'bit single-precision floats | +% |BIGARRAY_FLOAT64 |64'bit double-precision floats | +% |BIGARRAY_SINT8 |8'bit signed integers | +% |BIGARRAY_UINT8 |8'bit unsigned integers | +% |BIGARRAY_SINT16 |16'bit signed integers | +% |BIGARRAY_UINT16 |16'bit unsigned integers | +% |BIGARRAY_INT32 |32'bit signed integers | +% |BIGARRAY_INT64 |64'bit signed integers | +% |BIGARRAY_CAML_INT |31- or 63'bit signed integers | +% |BIGARRAY_NATIVE_INT|32- or 64'bit (platform-native) integers| +% -------------------------------------------------------------- +% The following example shows the passing of a two-dimensional big array to a +%C function and a Fortran function. +%<< +% extern void my_c_function(double * data, int dimx, int dimy); +% extern void my_fortran_function_(double * data, int * dimx, int * dimy); +% +% value caml_stub(value bigarray) +% { +% int dimx = Bigarray_val(bigarray)->dim[0]; +% int dimy = Bigarray_val(bigarray)->dim[1];

When writing this semantics, we have followed +the structure of part 2 of the Objective Caml manual: + +\begin{quote} + The Objective Caml system \\ + release 3.09 \\ + Documentation and user's manual \\ + Xavier Leroy (with Damien Doligez, Jacques Garrigue, Didier R\'emy and J\'er\^ome Vouillon) \\ + Copyright \copyright{} 2005 Institut National de Recherche en Informatique et en Automatique +\end{quote} + +Our aim is to describe a real language, including theoretically redundant but +practically useful features. We do not however cover the whole Objective Caml +language: we have omitted some major semantic features, such as objects and +modules. Our guideline is to retain the semantic features of core ML as +implemented in Objective Caml. Our language corresponds roughly to the +fragment presented in Chapter 1 of the Objective Caml manual. + +Supported features include: +\begin{itemize} +\item +the following primitive types and type constructors: \vtexttt{int}, \vtexttt{char}, +\vtexttt{string}, \vtexttt{float}, \vtexttt{bool}, \vtexttt{unit}, \vtexttt{exn}, \vtexttt{list}, +\vtexttt{option}, \vtexttt{ref}; +\item +tuple and function types +\ifHAVEtypedefinitions +\item +type and type constructor definitions, including: +\begin{itemize} +\item +type abbreviations (\eg \vtexttt{type t = int}), +\item +variant data and record types (\eg \vtexttt{type t = I of int $\|$ D of char} and \vtexttt{type t = \{f:int\} }), +\item +parametric type constructors (\eg \vtexttt{type 'a t = 'a -> 'a}), +\item +recursive and mutually recursive combinations of the above (although all +recursion must go through a variant data or record type); +\end{itemize} +\fi +\item +let-based polymorphism (with the traditional ML-style value restriction); +\item +31-bit word semantics for integers and IEEE-754 semantics for floating point +numbers (in the version of the system generated for HOL); +\item +type annotations (\eg \vtexttt{3:int}), list notation (\eg [1; 2; 3]), record +\vtexttt{with} expressions, \vtexttt{if} expressions, \vtexttt{while} expressions, +\vtexttt{for} expressions, sequencing (\vtexttt{;}), \vtexttt{assert} expressions; +\item +(potentially) mutually-recursive function definitions; +\item +pattern matching with nested patterns and \vtexttt{\} } patterns; +\item +mutable references through \vtexttt{ref}, \vtexttt{:=}, and \vtexttt{!}; +\ifHAVEmodules +%% ? +\fi +\item +exception definitions and handling (\vtexttt{try}, \vtexttt{raise}, \vtexttt{exception}); +\item +polymorphic equality (the \vtexttt{=} operator). +\end{itemize} + +The following features are not supported: +\begin{itemize} +\ifHAVEtypedefinitions +\item +mutable records (\eg \texttt{\{mutable l1=e1;...;mutable ln=en\} }); +\else +\item +type definitions; +\fi +\item +arrays; +\ifHAVEmodules +\item functors, named signatures, abstract signatures, module constraints +\item any form of subsignaturing, whether type abstraction, field erasure + or less polymorphic values +\else +\item +modules; +\fi +\item +subtyping, labels, polymorphic variants, objects; +\item +pattern matching guards (\texttt{when}); +\item +features documented in the ``language extensions'' part of the manual; +\item +\texttt{-rectypes}, exhaustivity of pattern matching, and other compiler command-line options; +\item +support for type abbreviations in the HOL model (we explain in the commentary +how they should be added); +\iffalse +\item a couple of really dark corners best left untold; +\fi +\item +finiteness of memory. +\end{itemize} + +This document contains a description of the language syntax +(\S\ref{sec.syntax}), a type system (\S\ref{sec.typing}) and an +operational semantics (\S\ref{sec.runtime}). + +\paragraph{Metatheory} +This typeset definition is generated by \texttt{ott}.

Functions + are then defined by case analysis, where the lhs and the rhs are + separated by the reserved symbol "===". + + The {{ hol-proof }} hom allows the specification of a termination + proof. + +- A new option -fast_parse generates a faster parser but + removes the possibility of disambiguating ambiguous terms using the + :non_terminal: syntax. + +- The generated Coq substitution functions now use the list_minus2 + auxiliary function rather than list_filter, as it is easier to + reason about (since rewriting under quantifiers does not work in + Coq). Added the -coq_use_filter_fn option for backwards + compatibility (*). + +- Introduced a new embed hom + + embed {{ coq-lib foo1 foo2 foo3 }} + + to avoid generation of functions foo1, foo2, foo3 (*) + +- No longer generate auxiliary list types for formula_dots in Coq + backend with -coq_expand_list_types true because today Coq now knows + how to generate the right induction principle. + +- Parsing of defns or embed is more robust wrt newlines (*). + +- Various bug-fixes (including #13487), improvements to error reports, + and performance optimisations. + +Entries labelled with (*) were contributed by Viktor Vafeiadis. + +2011.11.18 Version 0.21.1 + +This version fixes a packaging problem of the version 0.21. + +2011.12.9 Version 0.21.2 + +- fix bug 13645: forced use of :nonterm: syntax in conclusions of defn + rules in 0.21.1 (thanks to Karl Palmskog for reporting the bug). + +- Added new hom syntax {{* ... *}} that permits {{ and }} appearing + inside.

For any rule with such a hom, +we transform that rule by appending an "_aux" to its primary nonterminal +root name. We then add a synthesised rule with the original nonterminal +root name and a single production, with a shape described by the body of +the aux hom, which must be of the form + + {{ aux foo1 foo2 _ bar1 bar2 bar3 }} + +with a single _ and any number of strings fooi and barj before and +after, and no Raw_hom_ident's. The _ is replaced by the original +nonterminal root name. + +For example, given a grammar or metavariable l of source locations, one +might say + +ntr :: 'NTR_' ::= {{ aux _ l }} + | ... + +to synthesise grammars ntr_aux and ntr of unannotated and location-annotated +terms, the first with all the original productions and the second with a +single production + | ntr l :: :: NTR_aux. + +If the rule has an empty production name wrapper (eg with '' in place +of 'NTR_') then the production name is based on the original +nonterminal root, capitalised and with _aux appended (eg Ntr_aux), to +avoid spurious conflicts. + +Generation of aux rules is controlled by a command-line option +-generate_aux_rules {true|false}, which one might (eg) set to false +for latex output and true for OCaml output. + +- New {{ texlong }} hom on productions, letting long productions +be typeset with the production extending into the space usually used +for comment, pushing that onto the next line. + +2013.07.04 + +- replace "make" by "$(MAKE)" in Makefile.

This - EBNF is written out as LaTeX source. The output is a LaTeX "longtable" - environment, that can be included in any LaTeX document, typically - using an \input{} statement. - -What is the purpose of y2l? - - Questions about the purpose of things are so common, so here is the - answer to this very frequently asked question. When designing Abyss, I - found that I was continuously updating the grammar in two places. The - yacc description was of course the final authority. But I made it a - point to ensure that I would have decent and up-to-date documentation - for the language. Which led to the first incarnation of y2l. - - Then came the well known moment of truth when that first version was - used to try and generate an EBNF description for someone else's - grammar. That failed quite miserably because of implicit dependencies - on the format of the Abyss grammar description. A new y2l was written, - based around a strict yacc source file parser. It is designed to be - able to turn any yacc source file into an EBNF description, yet it - might choke on some Bison source files, because of large liberties the - authors of Bison have taken compared to the "original" yacc. This is - considered to be a "known bug" and might be solved in the future. - -What about portability? - - How portable is this little utility? Well, it's pretty portable in the - sense that is has been written in good ol' AWK! As long as you have a - machine with a sensible AWK (such as Gawk, or the one true AWK on - Brian Kernighan's homepage (http://plan9.bell-labs.com/cm/cs/who/bwk), - it will work. - - You may have to manually update the first line of the y2l script to - point to the proper AWK executable on your system. Not every system - has a sensible AWK as /usr/bin/awk! - -Where to download y2l? - - The latest release of y2l is available here for download - (http://y2l.sourceforge.net/download/y2l.tar.gz). - - The PGP signature for y2l is available at - http://y2l.sourceforge.net/download/y2l.tar.gz.asc. The signing key - can be found at the author's homepage (http://www.alchar.org/~aedil/). - - Anonymous read-only CVS access is available from SourceForge. Follow - these easy steps: - * cvs -d:pserver:anonymous@cvs.y2l.sourceforge.net:/cvsroot/y2l - login - * cvs -d:pserver:anonymous@cvs.y2l.sourceforge.net:/cvsroot/y2l co - y2l - * cvs update - You can use this in the y2l directory any time you wish to update - your local copy against the CVS repository. - -How to use y2l? - - The y2l manual is included in the distribution in Unix manpage format - and as an HTML file. The link in this section will bring you to the - most current HTML version of the y2l manual. - _________________________________________________________________ - - Last modified: Mar 7th, 2000 - ©1995-2000 by Aedil diff --git a/vendors/ott/aux/y2l/y2l b/vendors/ott/aux/y2l/y2l deleted file mode 100755 index 1c24dab2b755..000000000000 --- a/vendors/ott/aux/y2l/y2l +++ /dev/null @@ -1,1151 +0,0 @@ -#!/usr/bin/awk -f - -############################################################################### -# -# FILE: y2l -# DESCRIPTION: Yacc-to-LaTeX grammar processor -# -# Copyright (c) 1994-2000 by Kris Van Hees, Belgium.

1  Introduction

Ott is a tool for writing definitions of programming languages and -calculi. -It takes as input a definition of a language syntax and semantics, in -a concise and readable ASCII notation that is close to what one would -write in informal mathematics. It generates output: -

  1. -a LaTeX source file that defines commands to build a typeset version of -the definition; -
  2. a Coq version of the definition; -
  3. a HOL version of the definition; -
  4. an Isabelle/HOL version of the definition; -
  5. a Lem version of the definition; -
  6. an OCaml version of the syntax of the definition. -

-Additionally, it can be run as a filter, taking a -LaTeX/Coq/Isabelle/HOL/Lem/OCaml source file -with embedded (symbolic) terms of the defined language, parsing them and replacing -them by typeset terms.

This document is a user guide for the tool. The papers -

-give an overview of the project, including discussion of motivation, -design decisions, and related work, and one should look at that together -with this manual. The project web page -

-http://www.cl.cam.ac.uk/users/pes20/ott/ -

-links to the github source repository, with a -BSD-style licence. It also has a range of examples, including -untyped and simply typed CBV lambda calculus, ML polymorphism, various -first-order systems from Pierce’s TAPL [Pie02], the -POPLmark F<: language [ABF+05], a module system by -Leroy [Ler96, §4] (extended with a term language and an -operational semantics), the LJ Java fragment and LJAM Java module -system [SSP07], and a substantial fragment of OCaml.

Our main goal is to support work on large programming language -definitions, where the scale makes it hard to keep a definition -internally consistent, and hard to keep a tight correspondence between a -definition and implementations. -We also wish to ease rapid prototyping work with smaller calculi, -and to make it easier to exchange definitions and definition fragments -between groups. -Most simply, the tool can be used to aid completely informal LaTeX mathematics. -Here it permits the definition, and terms within proofs and -exposition, to be written in a clear, editable, ASCII notation, without LaTeX -noise. It generates good-quality typeset output. -By parsing (and so sort-checking) this input, it quickly catches a -range of simple errors, e.g. inconsistent use of judgement forms or -metavariable naming conventions. -That same input, extended with some additional data, can be used to generate formal definitions for -Coq, HOL, Isabelle, and Lem. It should thereby enable a smooth transition -between use of informal and formal mathematics. Further, the -tool can automatically generate definitions of functions for free -variables, single and multiple substitutions, subgrammar checks -(e.g. for value subgrammars), and binding auxiliary functions. -Ott supports a ‘fully concrete’ representation, sufficient -for many examples but not dealing with general alpha equivalence. -An experimental Coq backend generates definitions in locally-nameless style for a subset of the Ott metalanguage. -The OCaml backend -generates type definitions that may be useful for developing a complete -implementation of the language, together with the functions listed -above. It does not generate anything for inductively defined relations -(the various proof-assistant code extraction facilities can -sometimes be used for that). -Our focus here is on the problem of writing and editing language -definitions, not (directly) on aiding mechanized proof of metatheory. If one -is involved in hard proofs about a relatively stable small calculus -then it will aid only a small part of the work (and one might choose -instead to work just within a single proof assistant), but for larger -languages the definition is a more substantial problem — so much so -that only a handful of full-scale languages have been given complete definitions. We -aim to make this more commonplace, less of a heroic task.

2.3  To build

-

2.3.1  With OPAM

If you have OPAM installed on your -system, opam install ott will install the latest Ott version. -The Emacs mode will be in -‘opam config var prefix‘/share/emacs/site-lisp, and -documentation in ‘opam config var prefix‘/doc/ott.

To install the Ott auxiliary files for Coq, first activate the -coq-released OPAM repository:

opam repo add coq-released https://coq.inria.fr/opam/released

and then run opam install coq-ott.

-

2.3.2  Without OPAM

Ott depends on OCaml version 4.00.0 or later. It builds with (at least) -OCaml 4.02.3.

The command make (make world) builds the ott -binary in the bin/ subdirectory.

This will compile Ott using ocamlopt. To force it to compile -with ocamlc (which may give significantly slower execution of -Ott), do make world.byt.

To build the Ott auxiliary files for Coq, go to the coq/ -subdirectory and run make. To install the resulting files in -Coq’s user-contrib, run make install.

-

2.4  To run

Ott runs as a command-line tool. Executing bin/ott shows the -usage and options. To run Ott on the test file -tests/test10.ott, generating LaTeX in test10.tex and -Coq in test10.v, type:

bin/ott -i tests/test10.ott -o test10.tex -o test10.v

Isabelle, HOL, and Lem can be generated with options --o test10.thy, -o test10Script.sml, and --o test10.lem, respectively.

The Makefile has various sample targets, make tests/test10.out, -make test7, etc. Typically they generate:

ll - -

- - - - - - -
filenamedescription
out.texLaTeX source for a definition
out.psthe postscript built from that
out.vCoq source
outScript.smlHOL source
out.thyIsabelle source

from files test10.ott, test8.ott, etc., in -tests/.

-

2.5  Manual

-

2.6  Editor Plugins

-

2.6.1  Emacs mode

The file emacs/ott-mode.el defines a very simple Emacs mode for -syntax highlighting of Ott source files. It can be used by, for example, -adding the following to your .emacs file, replacing -PATH by a path to your Ott Emacs directory.

(setq load-path (cons (expand-file-name "PATH") load-path))
-(require 'ott-mode)
-

For installations using OPAM on *nix systems, it is sufficient to use -the following code, which will call opam config var prefix at -load-time.

(setq opam-share (substring (shell-command-to-string "opam config var share") 0 -1))
-(add-to-list 'load-path (concat opam-share "/emacs/site-lisp"))
-(require 'ott-mode)
-
-

2.6.2  Visual Studio Code

There is a -plugin -for VSCode, which features syntax highlighting and inline error -reporting.

-

2.7  Mailing lists

-

2.8  Web page with examples

-

2.9  Copyright information

The ocamlgraph library is distributed under the LGPL (from -http://www.lri.fr/∼filliatr/ftp/ocamlgraph/); we include -a snapshot for convenience. For its authorship and copyright information -see the files therein.

3  A minimal Ott source file: the untyped CBV lambda calculus

Fig. 1 shows an Ott source file for an untyped call-by-value -(CBV) lambda calculus. This section explains the basic features that -appear there, while in the following sections we show what must be -added to generate typeset output, proof assistant definitions, and -other things. -

Figure 1: Source: test10.0.ott
-

-The figure is colourised, with Ott keywords like this and Ott -symbols such as | and ::. Other user-specific input -appears like this.

At the top of the figure, the metavar declaration introduces -a sort of metavariables termvar (with synonym x), for term -variables. -The following grammar introduces two grammar rules, one for terms, with -nonterminal root -t, and one for values v. -This specifies the concrete syntax of object-language terms, -the abstract syntax representations for proof-assistant mathematics, -and the syntax of symbolic terms to be used in semantic rules.

Each rule has a rule name prefix (e.g. ’t_’) and then a list -of productions. Each production, e.g. -

-  | \ x . t      ::  :: Lam
-

-specifies a syntactic form as a list of elements, here ‘\’, -‘x’, ‘.’, and ‘t’, each of which is either a -metavariable (the ‘x’), a nonterminal (the ‘t’), or a -terminal -(\ . ( ) { } / -->). -Within productions all elements must be whitespace-separated, so that -the tool can deduce which are terminals. In the symbolic terms in -the semantic rules below, however, whitespace is required only where necessary. -A few terminals have to be quoted (with '') if they appear in a grammar, e.g. to -use | as an object-language token, as they are part of the Ott syntax, but they -do not have to be quoted at usage points. -(If one accidentally omits inter-token whitespace in the grammar, the -output of Ott can be surprising. This is best diagnosed by looking at -the colourised ASCII or LaTeX output from Ott.)

Metavariables and nonterminals can be formed from the specified -metavariable and nonterminal roots by appending a suffix, e.g. the -nonterminal t' in the App and Tsub productions.

Between the ::’s is an optional meta flag M or S. Non-meta -productions give rise to clauses of datatype definitions in the -Isabelle/Coq/HOL output, whereas meta productions do not. Later, we -will see how the user can specify how meta syntax should be translated -away when generating proof assistant output. The two flags M -and S are identical except that productions with the latter are -admitted when parsing example concrete terms; the S tag is thus -appropriate for lightweight syntactic sugar, such as productions for -parentheses. One can also use an X flag here to suppress a -production in the generated LaTeX.

Each production has a production name (e.g. t_Lam), composed of -the rule name prefix (here t_) and the production name kernel -that follows the ::’s (here Lam). The production name is -used as a constructor name in the generated Isabelle/Coq/HOL.

The tool supports arbitrary context-free grammars, extended with -special constructs for list forms (c.f. §12).

Following the grammar in this example is a subrule -declaration -

-  subrules
-    v <:: t
-

-declaring that the v grammar rule (of values) is a -subgrammar of the t rule (of terms). The tool checks that -there is in fact a subgrammar relationship, i.e. that for each -production of the lower rule there exists a production of the higher -rule with corresponding elements (up to the subrule relation). -The subrule declaration means that, in the semantic rules below, we -will be able to use v’s in places where the grammar specifies t’s. -In the generated Isabelle/Coq/HOL for this example only one free -datatype will be generated, for the t rule, while for the v -rule we generate an is_v predicate over the t type. Usages of -v nonterminals in the semantic rules will have instances of this -predicate automatically inserted.

Finally, we give a collection of definitions of inductive relations. -In this example there is just one family of definitions (of -operational judgements), introduced by the defns Jop; it contains just one -definition of a relation, called reduce. -In general there may be many defns blocks, each of which introduces a -mutually recursive collection of defns. -The relation definition -defn ... -also includes a grammar production specifying how elements of the -relation can be written and typeset, here -

  t1 --> t2
-

As in the main grammar, the tokens of this syntax definition in the -header must be space-separated, but usages of the syntax generally -need not be. -Syntax rules for each family of -judgements, and for their union, are implicitly generated. -The relation definition is given by a sequence of inference rules, -each with a horizontal line separating a number of premises from a -conclusion, for example as below. -

-    t1 –> t1’
-    -------------- :: ctx_app_arg
-    v t1 –> v t1’
-

-The conclusion must be a symbolic term of the form of the judgement being -defined. -In simple cases (as here) the premises can be symbolic terms of the -form of any of the defined judgements. More generally (see -§6) they can be symbolic terms of a user-defined -formula grammar, or in-line embedded prover code. -Each rule -has a name, composed of a definition family prefix -(here empty), a definition prefix (here also empty) and a kernel -(the ctx_app_arg). -

The symbolic terms in semantic rules are parsed with a scannerless parser, built -using parser combinators over character-list inputs. The parser -searches for all parses of the input. If none are found, the ASCII -and TeX output are annotated no parses, with a copy of the -input with *** inserted at the point where the last token was -read. This is often at the point of the error (though if, for -example, a putative dot form is read but the two element lists cannot -be anti-unified, it will be after the point of the error). -If multiple parses are found, the TeX output is annotated -multiple parses and the different parses are output to the -console in detail during the Ott run. -If the option picky_multiple_parses is set to -true, multiple parses are always reported. If it set to -false, a symbolic term is considered ambiguous only if two -different parses compile to different strings (for a target). -The parser combinators use memoization and continuation-passing to -achieve reasonable performance on the small symbolic terms that are -typical in semantic rules. Their performance on large (whole-program -size) examples is untested. -To resolve ambiguity one can add metaproductions for parentheses (as -in Fig. 1), or -production-name annotations in particular symbolic terms, -e.g. the :t_tsub: in the AppAbs rule of the POPLmark -example, -test7.ott. There is currently no support for precedence -or associativity.

This file is included in the distribution as -tests/test10.0.ott. It can be processed by executing -

-   bin/ott -i tests/test10.0.ott
-

-from the main directory. This simply reads in the file, checking that -it is well-formed. Adding options: -

-   bin/ott -show_sort true -show_defns true -i tests/test10.0.ott
-

-it echos a colourised version to the screen, -with metavariables in red, nonterminals -in yellow, terminals in green, and object variables in white. -The colourisation uses vt220 control codes; if they do not work on -your screen add -colour false to the middle of the command -line. To suppress the echo of the definition, add --show_post_sort false and -show_defns false.

-

3.1  Index variables

-In addition to the metavar declarations above, the user can declare any number of distinguished index -metavariables, e.g. by: -

-  indexvar index, i, j, n, m ::= {{ isa num }} {{ coq nat }} {{ hol num }} 
-

-Given such a declaration, index, i, j, n -and m can be used in suffixes, e.g. in the production -

-   |  ( t1 , .... , tn )           :: :: Tuple
-

-There is a fixed ad-hoc language of suffixes, including numbers, primes, and index variables (see §23). -Index metavariables cannot themselves be suffixed.

-

4  Generating LaTeX

The example from the previous section can already be used to generate -LaTeX, for example by executing -

-   bin/ott -i tests/test10.0.ott -o out.tex 
-

-to produce a LaTeX file out.tex. One often needs to -fine-tune the default typesetting, as illustrated in -Figure 2 (the Ott source) and Figure 3 -(the resulting LaTeX). -(The latter was built using the additional option -tex_show_meta false, to -suppress display of the metaproductions.) -

-The source file has three additions to the previous file. -Firstly, the metavar declaration is annotated with a -specification of how metavariables should be translated to LaTeX: -

-  metavar termvar, x ::=   
-    {{ tex \mathit{[[termvar]]} }}
-

-Inside the {{ tex }} -is some LaTeX code -\mathit{$[[termvar]]$} -giving the translation of a termvar or x. Here they -are typeset in math italic (which in fact is also the default). -Within the translation, the metavariable itself can be mentioned -inside double square brackets [[ ]].

Secondly, there is a grammar for a distinguished nonterminal root -terminals, with a -{{ tex }} -translation for each, overriding the default typesetting of some -terminals. Note that the other terminals -(. ( ) { } /) -are still given their default typesetting. -

-  terminals :: ’terminals_’ ::=
-    | \            ::  :: lambda  {{ tex \lambda }}
-    | –>          ::  :: red     {{ tex \longrightarrow }}
-

-Thirdly, the file has com comments, including -the -{{ com term }} -attached to a grammar rule, -the -{{ com variable}} -attached to a production, and the -{{ com [[t1]] reduces to [[t2]]}} -attached to a semantic relation. These appear in the LaTeX output -as shown in Figure 3.

-

4.1  Specifying LaTeX for productions

-One can also specify tex translations for productions, overriding the default -LaTeX typesetting, e.g. as in this example of -a type abstraction production. -

-    |  X <: T . t   :: :: TLam   {{ tex \Lambda [[X]] [[<:]] [[T]]. \, [[t]] }}
-

-These homomorphisms, or homs1, can refer to the metavariables and -nonterminals that occur in the production, e.g. the [[X]], -[[T]], and [[t]] in the tex hom above, -interleaved with arbitrary strings and with typeset elements of the -terminals grammar, e.g. the [[<:]].

Homomorphisms are applied recursively down the structure of symbolic -terms. For example, an F<: term -

  (\X<:T11.t12) [T2]
-

would be LaTeX-pretty-printed, using the tex clause above, as -

( \, \Lambda  \mathit{X} <: \mathit{T_{\mathrm{11}}} . \, \mathit{t_{\mathrm{12}}} \, )
- \, \, [ \, \mathit{T_{\mathrm{2}}} \, ]
-

which is typeset as below. -

-
-

-Note the X, T11 and t12 of the symbolic term are -used to instantiate the formal parameters X, T and -t of the homomorphism definition clause. -If the t itself had compound term structure, e.g. as below -

  (\X<:T. \X'<:T'.x)
-

the homomorphism would be applied recursively, producing -

( \, \Lambda  \mathit{X} <: \mathit{T} . \,  \Lambda  \mathit{X'} <: \mathit{T'} 
-. \,  \mathit{x} \,  \, )
-

typeset as follows. -

-
-

-Where there is no user-supplied homomorphism clause the LaTeX -pretty-printing defaults to a sequence of the individual items -separated by thin spaces (\,), -with reasonable default fonts and making use of the terminals grammar where appropriate.

-

4.2  Specifying LaTeX for grammar rules

-Grammar rules can include a tex hom specifying how all the -nonterminal roots should be typeset, e.g. -

-  type, t, s :: Typ_ ::=  {{ tex \mathsf{[[type]]} }} 
-        | unit                  ::   :: unit   
-        | type * type’          ::   :: pair   
-        | type -> type’         ::   :: fun    
-

Alternatively, the individual nonterminal roots can have tex -homs specifying how they should be typeset: -

-  G {{ tex \Gamma }} , D {{ tex \Delta }} :: ’G_’ ::= 
-        | empty                 ::   :: empty       
-        | G , x : T             ::   :: term        
-

-permitting the user to write G', D12 etc. in symbolic -terms, to be typeset as - -etc.

-

4.3  Using the LaTeX code

The generated LaTeX code can be used in two main ways. -By default, Ott generates a stand-alone LaTeX file, -with a standard wrapper (including a \documentclass, various -macro definitions, and a main body), -that gives the complete system definition.

The default header can be overridden by writing - embed {{ tex-wrap-pre ... }} and the default footer by -writing embed {{ tex-wrap-post ... }} . Alternatively, the -program option -tex_wrap false with the -tex_wrap false -command-line argument, one can generate a file that can be included in -other LaTeX files, that just defines macros to typeset various -parts of the system (-tex_wrap false overrides any -tex-wrap-pre/tex-wrap-post embeds).

The generated LaTeX output is factored into individual LaTeX -commands: for the metavariable declarations, each rule of the syntax -definition, the collected syntax (\ottgrammar), each rule of the inductive relation -definitions, the collected rules for each relation, the collected -rules for each defns block, the union of those -(\ottdefns) and the whole (\ottall). -This makes it possible to quote individual parts of the definition, -possibly out-of-order, in a paper or technical report.

If one needs to include more than one system in a single LaTeX -document, the ott prefix can be replaced using the --tex_name_prefix command-line argument.

The generated LaTeX is factored through some common style macros, -e.g. to typeset a comment, a production, and a grammar. If necessary -these can be redefined in an embed block (see Section 8.1). -For example, the file tests/squishtex.ott -

-embed 
- {{ tex-preamble
-\renewcommand{\[[TEX_NAME_PREFIX]]grammartabular}[1]
-  {\begin{minipage}{\columnwidth}\begin{tabular}{ll}#1\end{tabular}\end{minipage} }
-\renewcommand{\[[TEX_NAME_PREFIX]]rulehead}[3]
-  {$#1$  $#2$ & $#3$}
-\renewcommand{\[[TEX_NAME_PREFIX]]prodline}[6]
-  { \quad $#1$ \ $#2$ & \quad $#3 #4$  $#5$  $#6$}
-\renewcommand{\[[TEX_NAME_PREFIX]]interrule}
-  {\\[2.0mm]}
- }}
-

- -defines a more compact style for grammars. Note that the -[[TEX_NAME_PREFIX]] is replaced by whatever prefix is in force, -so such style files can be reused in different contexts.

A more sophisticated LaTeX package ottlayout.sty, providing fine control of how -inference rules and grammars should be typeset, is contained in the -tex directory of the distribution. It is described in the -manual therein.

-

5  Generating proof assistant definitions

To generate proof assistant definitions, for Coq, Isabelle, and HOL, -the minimal Ott source file of Section 3/Figure 1 must -be extended with a modest amount of additional data, as shown in Figure 4. -Executing -

-   bin/ott  -i tests/test10.4.ott  -o out.v  -o out.thy  -o outScript.sml 
-

-generates Coq out.v, Isabelle out.thy, and HOL -outScript.sml, shown in Figures 5, 6, and 7. -The additional data can be combined with the annotations for -LaTeX of the previous section, but those are omitted here. -

Figure 4: Source: test10.4.ott
-

-We add four things. -First, we specify proof assistant types to represent object-language -variables — in this example, choosing the string type of -Isabelle and HOL, and the nat type for Coq: -

-  metavar termvar, x ::=  
-  {{ isa string}} {{ coq nat}} {{ hol string}} {{ coq-equality }}
-

-For Coq output, one can specify {{ coq-equality proof-script }} -to build a decidable equality over the Coq representation type using -the proof proof-script. If the script is omitted, as in this -example, it defaults -to -

Proof.
-  decide equality; auto with ott_coq_equality arith.
-Defined.
-

where the ott_coq_equality database contains the decidable -equalities of the representation types defined in the source. It is -possible to suppress type generation for specific metavariables or nonterminals, by adding the -declaration {{ phantom }}. This is useful in some cases, for -instance to avoid duplicate definitions of types already defined in an -imported library. Any type homs are taken into account when -the metavariable or nonterminal root is output as a type.

Second, we specify what the binding is in the object language, with -the (+ bind x in t +) -annotation on the Lam production: -

-  | \ x . t      ::  :: Lam     (+ bind x in t +)
-

-Section 9 describes the full language of binding specifications.

Third, we add a block -

-  substitutions
-    single t x :: tsubst 
-

-to cause Ott to generate Coq/Isabelle/HOL definitions of a substitution -function, with name root tsubst, replacing metavariables x by terms t. This is for single -substitutions; multiple substitution functions (taking lists of -substitutand/substitutee pairs) can also be generated with the keyword -multiple. -Substitution functions are generated for all rules of the grammar for -which they might be required — here, just over t, with a -function named tsubst_t.

Finally, we specify translations for the metaproductions: -

-  | ( t )        :: S:: Paren   {{ icho [[t]]  }} 
-  | { t / x } t’ :: M:: Tsub    {{ icho (tsubst_t [[t]] [[x]] [[t’]])}}
-

-These specify that (t) should be translated into just the -translation of t, whereas -{t/x}t’ should be translated into the -proof-assistant application of tsubst_t to the translations -of t, x, and t’. -The (admittedly terse) icho specifies that these translations should be -done uniformly for Isabelle, Coq, HOL, and OCaml output. One can also -specify just one of these, writing -{{ coq }}, -{{ hol }}, -{{ isa }}, or -{{ ocaml }}, -or include several, with different translations for each. -There are also abbreviated forms ich, ic, ch, and ih. -The body of a proof assistant hom should normally include outer -parentheses, as in the Tsub hom above, so that it is -parsed correctly by the proof assistant in all contexts.

5.1  Proof assistant code for grammar rules

-The normal behaviour is to generate a free proof assistant type for -each (non-subrule, non-phantom) grammar rule. -For example, the Coq compilation for t here generates a free type with three -constructors: -

  Inductive term : Set := 
-   | t_var (x:var)
-   | t_lam (x:var) (t:term)
-   | t_app (t:term) (t':term).
-

(note that the metaproductions do not give rise to constructors).

Remark: prior to version 0.20.2, the free type generated for Coq was -

  Inductive term : Set := 
-   | t_var : var -> term
-   | t_lam : var -> term -> term
-   | t_app : term -> term -> term.
-

but we found that trying to preserve the names specified by the user -is helpful later, when doing proofs. Whenever a clash is detected, or -for list forms, the wildcard _ is used. The old behaviour -can be obtained via the top-level option --coq_names_in_rules false.

By default the order of the arguments to those constructors follows -the order in which they appear in the production. That can be -overridden with an order hom. For example, if for some -reason (perhaps compatibility with other Coq code) one wished the -arguments to t_Lam to be reversed: -

   | t_Lam : t -> termvar -> t
-

one could add an order hom as below. -

-  | \ x . t      ::  :: Lam  {{ order [[t]] [[x]] }}
-

Instead of using the generated free type, one can specify an arbitrary proof assistant representation type, -annotating the grammar rule with a coq, isa, hol, or ocaml hom — -for example, in the following grammar for substitutions. -

-  s {{ tex \sigma }} :: ’S_’ ::= {{ com multiple subst }} {{ isa (termvar*t) list }}
-       | [ x |-> t ]            ::   :: singleton   {{ isa [ ([[x]],[[t]]) ]  }}
-       | s1 , .. , sn           ::   :: list        {{ isa List.concat [[s1 .. sn]] }}
-

-Here the {{ isa (termvar*t) list }} hom specifies that in -Isabelle output this type be represented as an Isabelle -(termvar*t) list instead of the default free inductive type; -all the productions are metaproductions (tagged M); and isa homs for each production specify how they should be translated into that Isabelle type. -This feature must be used with care, as any Ott-generated functions, e.g. substitution functions, cannot recurse through such user-defined types.

Grammar rules (whether free or non-free) can also include a coq equality hom, instructing -the Coq code generator to derive a decidable equality for the Coq -representation type. For example, the ML polymorphism Ott source of -test8.ott includes the following. -

-  typvar :: TV_ ::= {{ coq-equality decide equality. apply eq_value_name_t. }}
-       | ’ ident                ::   :: ident
-

The Coq/HOL/Isabelle/OCaml type name for a grammar rule, or for a -metavariable declaration, is normally -taken to be just its primary nonterminal root. -Occasionally it is useful to work around a clash between a -metavar or nonterminal primary root and a proof assistant symbol, -e.g. T in HOL or value in Isabelle. -For this, one can add a coq, hol, isa, or -ocaml hom to the primary nonterminal root. In the example -below, the user can write T, T’ etc. in their Ott -source, but the generated HOL type is Typ. -

-T {{ hol Typ }}, S, U :: ’T_’ ::=                    {{ com type  }}
-  | T -> T’                          :: :: Fun          {{ com type of functions }}
-

The grammar rules within each grammar block of a syntax definition may depend on each other arbitrarily. -When generating Isabelle/Coq/HOL/OCaml representation types, however, they are -topologically sorted, to simplify the resulting induction -principles.

-

5.2  Proof assistant code for inductive definitions

-The semantic relations are defined -with the proof-assistant inductive relations packages, -Inductive, Hol_reln, and inductive_set or inductive, respectively. -Each defns block gives rise to a potentially mutually -recursive definition of each defn inside it -(it seems clearer not to do a topological sort here). -Definition rules are expressed internally with symbolic terms. -We give a simplified grammar thereof in Fig. 17, omitting the -symbolic terms for list forms. -A symbolic term st for a nonterminal root is either an explicit nonterminal or a -node, the latter labelled with a production name and containing a list of -symterm_elements, which in turn are either symbolic terms, -metavariables, or variables. -Each definition rule -gives rise to an implicational clause, essentially -that the premises (Ott symbolic terms of the formula grammar) -imply the conclusion (an Ott symbolic term of whichever judgement is -being defined). -Symbolic terms are compiled in several different ways: -

  • -Nodes of non-meta productions are output as applications of the appropriate proof-assistant constructor (and, for a subrule, promoted to the corresponding constructor of a maximal rule). -
  • Nodes of meta productions are transformed with the user-specified homomorphism. -
  • Nodes of judgement forms are represented as applications of the defined relation in Coq and HOL, and as set-membership assertions in Isabelle. -
  • Lists of formulae (the formula_dots production, c.f.§12) are -special-cased to proof-assistant conjunctions. -

-Further, for each nonterminal of a non-free grammar rule, -e.g. a usage of v' where v<::t, an additional premise -invoking the generated subrule predicate for the non-free rule is added, e.g. is_v v'. -For Coq and HOL, explicit quantifiers are introduced for all variables -mentioned in the rule. -For HOL, rules are tagged with their rule name (using clause_name).

-

5.3  Representation of binding

-At present the generated Isabelle/Coq/HOL uses fully concrete -representations of variables in terms, without any notion of alpha -equivalence, as one can see in Fig. 6: -see the t datatype of terms and the tsubst_t -substitution function there. -An experimental Coq backend generates definitions in locally-nameless style for a subset of the Ott metalanguage. This is work-in-progress, and it is extensively documented in http://moscova.inria.fr/ zappa/projects/ln_ott/. -We intend in future to generate other representations, and in some -circumstances homs can be used to implement other representations directly. -For a reasonably wide variety of -languages, however, one can capture the intended semantics of whole programs in -this idiom, subject only to the condition that standard library -identifiers are not shadowed within the program, as the operational -semantics does not involve reduction under binders — so any -substitutions are of terms which (except for standard library -identifiers) are closed. This includes the ML polymorphism example of -test8.ott. For languages which require a type -environment with internal dependencies, however, for example F<:, this is -no longer the case. The POPLmark F<: example given in test7.ott -has a type system which disallows all shadowing, a property that is -not preserved by reduction. However, a correct translation of F<: is generated by the Coq locally-nameless backend, and can be found in http://moscova.inria.fr/ zappa/projects/ln_ott/.

Further discussion of binding representations is in the Ott ICFP 2007 -paper and in a working draft -

Binding and Substitition. Susmit Sarkar, Peter Sewell, and Francesco -Zappa Nardelli. August 2007. -

-available from the Ott web page.

-

5.4  Helper functions for free variable and substitution functions

The generated free variable and substitution functions in the Coq output -(e.g., in Figure 5) often rely on a few standard library functions: -list_mem, list_assoc, list_minus, list_minus2. -In order to avoid dependencies on external libraries for defining those -functions, by default Ott generates the definitions for any such functions it -uses. It is possible to turn off the generation of definitions for -these such functions by writing the following directive early on in the source file:

-embed {{ coq-lib list_mem list_minus }}
-

This instructs Ott to avoid generating definition for list_mem and -list_minus, but to continue generating definitions for other functions -such as list_assoc and list_minus2.

Note about list_minus2: -Instead of using the function list_minus2, earlier versions of Ott -generated equivalent code based on list_filter, which was more -difficult to reason about. For backwards compatibility, however, we provide the -command-line option -coq_use_filter_fn for generating a definition using -the older code pattern.

-

5.5  Correctness of the generated proof assistant code

-We have attempted to ensure that the proof assistant definitions -generated by Ott are well-formed and what the user would intend. This -is not guaranteed, however, for several reasons: (1) There may be name -clashes between Ott-generated identifiers and proof assistant built-in -identifiers (or, in pathological cases, even among different -Ott-generated identifiers). (2) In some cases we depend on automatic -proof procedures, e.g. for HOL definitions. These work in our test -cases, but it is hard to ensure that they will in all cases. More -importantly, (3) the generation process is complex, so it is quite -possible that there is either a bug in Ott or a mismatch between the -user expectation and what the tool actually does. Ultimately one has -to read the generated proof assistant definitions to check that they -are as intended — but typically one would do this in any case, many -times over, in the process of proving metatheoretic results, so we do -not consider it a major issue.

-

5.6  Using the generated proof assistant code

-Note added 2017-11-30: the following is out of date.

Ott builds code for

- - -
Coq 8.3http://coq.inria.fr/
HOL 4 (the current svn version)http://hol.sourceforge.net/
Isabelle/HOL (Isabelle 2011)http://isabelle.in.tum.de/

Given proof assistant files in the top-level directory of the -distribution, as produced at the start of this section -(Coq out.v, Isabelle out.thy, and HOL -outScript.sml), the various proof assistants can be invoked as follows.

-

5.6.1  Coq

-First run -

  make
-

in the coq directory of the distribution, to build the auxiliary files. -These include a core file (ott_list_core) of definitions that -are used in Ott-generated output. -At present these are only required when Coq native lists are used. -There are also various lemmas (in -ott_list.v) which may be useful; they can be made available with -Require Import ott_list.

For batch mode run -

  coqc -I coq  out.v
-

where coq is the path to the coq directory of the distribution.

The experimental locally-nameless backend requires the Metatheory library by Arthur Chargueraud, available from the project web page.

-

5.6.2  HOL

-First run -

  Holmake
-

in the hol directory of the distribution, to build the auxiliary files.

For -batch mode run -

  Holmake -I hol  outTheory.uo
-

where hol is the path to the hol directory of the distribution. -For interactive mode, run -

  hol -I hol
-

inside an editor window (where the second hol is again the path -to the hol directory of the distribution), and in -another window view the outScript.sml file. First -paste in the app load command from a comment at the top of the -file, then paste in the remainder.

-

5.6.3  Isabelle

-For batch mode: -

  echo 'ML_command {* (use_thy "Tmp"; OS.Process.exit OS.Process.success) handle e => (OS.Process.exit OS.Process.failure); *}' | /usr/local/Isabelle/bin/isabelle tty 
-

Interactively, using Proof General: -

  isabelle emacs out.thy
-
-

6  Judgments and formulae

In a semantic rule, for example -

-    t1 –> t1’
-    -------------- :: ctx_app_arg
-    v t1 –> v t1’
-

-the conclusion must be a symbolic term of the form of the judgement being -defined, but in general the premises may be symbolic terms -of a formula grammar or in-line embedded prover code. -By default the formula grammar includes all the defined judgement forms: for the -running example Ott will synthesise grammars as below.

The user can also define an explicit formula grammar, to let other -forms (not just judgements) appear as rule premises. Below is a -fragment of the formula grammar from the LJ example on the Ott web page. -

-  formula :: formula_ ::=  
-   |  judgement                       ::   :: judgement
-   |  formula1 .. formulan            ::   :: dots
-   |  not formula                     :: M :: not
-          {{ tex \neg [[formula]] }} 
-          {{ isa \<not> ([[formula]]) }}
-   |  ( formula )                     :: M :: brackets
-          {{ tex ([[formula]]\!) }}  
-          {{ isa [[formula]] }}
-   |  formula \/ formula:: M :: or
-          {{ tex [[formula]] \vee [[formula]] }}
-          {{ isa [[formula]] \<or> [[formula]] }}
-   |  formula /\ formula:: M :: and
-          {{ tex [[formula]] \wedge [[formula]] }}
-          {{ isa [[formula]] \<and> [[formula]] }}
-   |  x = x’                          :: M :: xali
-          {{ isa [[x]] = [[x’]] }}
-   |  X = X’                          :: M :: Xali
-          {{ isa [[X]] = [[X’]] }}
-

-This example adds (to the judgement forms) syntax for parenthesised -formulae, negation, and, or, and equality testing on two sorts. For -each, tex and isa homs specify how they should be -typeset and be translated into Isabelle.

If the user defines a formula grammar then (as here) the production -name prefix must be formula_ and the name for the -judgement production must be judgement.

-

6.1  Naming of premises for the Coq backend

-It is possible to specify the names of premises of inductive -predicates; these names are then used by the Coq backend, and are -often useful in proofs. For instance, we can call RED the hypothesis in the rule below -

-    t1 –> t1’  [[:RED]]
-    -------------- :: ctx_app_arg
-    v t1 –> v t1’
-

-which will then generate the following Coq code: -

-| ctx_app_arg : forall (v t1 t1’:term)
-    (RED: reduce t1 t1’),
-    is_val_of_term v ->
-    reduce (t_app v t1) (t_app v t1’).
-

-Names of rules cannot contain spaces or other non alpha-numerical -characters, and must begin with a letter. The name annotation must at -the rightmost place on the hypothesis line, and must be enclosed -(without spaces) between the [[: and ]] parentheses.

-

6.2  In-line embedded prover code in premises

-Instead of adding a formula production, one can directly embed prover -code as a premise, delimited as below by {{ and -}}. Within that, text will be echoed -directly to a prover (or given a default LATEX typesetting) except that symbolic terms enclosed within -[[ and ]] will be processed as in an -embed section. -

-  {{ type_to_chunk ([[typeof e1]]) = Some [[c]] }}
-  ----------------------------------------------------------- :: Assign1
-  e1=e2 . k |env   –tau–>    lval(e1) . [__=c e2] . k |env
-
-

6.3  User syntax

-The tool also synthesises a user_syntax grammar of all the -user syntax, for example:

This is used for parsing top-level strings, for example when filtering -embedded code (§8).

-

7  Concrete terms and OCaml generation

In semantic definitions, one typically never uses concrete variables, -only metavariables that range over them. -In examples, however, one may need either a mix of concrete variables -and metavariables, or, for strictly concrete terms, to restrict to -just the former (and also to prohibit symbolic nonterminals).

Figure 2 combines the LaTeX and proof assistant -annotations of Sections 3 and 4, adding a -{{ lex alphanum}} -hom -to the metavar declaration to specify the lexical form of -concrete variables of this sort. -At present a lex homomorphism must have body either -Alphanum (standing for [A-Z]([A-Z]|[a-z]|[0-9]|'|_)*), -alphanum (for ([A-Z]|[a-z])([A-Z]|[a-z]|[0-9]|'|_)*), -alphanum0 (for [a-z]([A-Z]|[a-z]|[0-9]|'|_)*), or -numeral (for [0-9][0-9]*); more general regular expressions are not supported. -An identifier that can be ambiguously lexed as either a concrete or -symbolic metavariable, e.g. x in the scope of the above -declaration, will be taken to be symbolic. -To restrict the parser to strictly concrete terms only, one can add a -:concrete: prefix, as shown in Figure 10.

One can also specify how concrete variables should be LaTeX’d or -translated into a proof assistant, e.g. with -homomorphisms -{{ texvar \mathrm{[[termvar]]}} -and -{{ isavar ’’[[termvar]]’’}} -(and similarly coqvar, holvar, and ocamlvar).

Figure 2 also specifies an OCaml representation type for -variables, with the metavar hom -{{ ocaml int}}. -Executing -

-   bin/ott -i tests/test10.ott -o test10.ml  
-

-produces the OCaml code shown in Figure 9, including OCaml -types to represent the abstract syntax, and auxiliary functions for -subrules and substitutions. This does not implement the semantic -rules. In some cases the various proof assistant code extraction -facilities can be used — see Section 21.

8  Filtering: Using Ott syntax within LaTeX, Coq, Isabelle, -HOL, or OCaml

-

8.1  Filtering embedded code

It is possible to embed arbitrary code in -the Ott source using an embed block, which can contain -tex, -coq, -hol, -isa, or -ocaml homomorphisms, the -bodies of which will appear in the respective output. -The embed keyword should be on a line by itself). For -example, -test8.ott contains the following to -define Coq and HOL remove_duplicates functions. -

-embed
-{{ coq
-Fixpoint remove_duplicates (l:list typvar_t) : list typvar_t :=
-  match l with
-  | nil => nil
-  | cons h t => if (list_mem eq_typvar_t h t)  then remove_duplicates t
-                else cons h (remove_duplicates t)
-end. }}
-
-{{ hol
-val _ = Define ‘
-  (remove_duplicates [] = []) /\
-  (remove_duplicates (x::xs) = if (MEM x xs) then remove_duplicates xs 
-                               else x::(remove_duplicates xs))
-‘; }}
-

-Within the body of an embed homomorphism, any text between -[[ and ]] will be parsed as a symbolic term (of the -user_syntax grammar) and pretty printed, so one can use user -syntax within LaTeX or proof assistant code. An Isabelle example -is below, defining an Isabelle function to calculate the order of a -type with productions unit, t*t', and t->t'. -

-{{ isa
-consts
-order :: "type => nat"
-primrec
-"order [[unit]] = 0"
-"order [[t*t’]] = max (order [[t]]) (order [[t’]])"
-"order [[t->t’]] = max (1+order [[t]]) (order [[t’]])"
-
-}}
-

-It is often useful to define a proof assistant function, in an -embed section, together with a production of the formula -grammar with a proof assistant hom that uses that function, thereby -introducing syntax that lets the function be used in semantic rules.

Ott also permits embed blocks with tex-preamble, -homs, whose -contents appear in the generated LATEX preamble. -Any definitions of LATEX commands must appear in such a -tex-preamble section. -

-

8.2  Filtering files

-Similar processing can be carried out on separate files, using the -command-line options tex_filter, isa_filter, etc. -Each of these takes two arguments, a source filename and a destination -filename. In processing the source file, -any text between -[[ and ]] will be parsed as a symbolic term (of the -user_syntax grammar) and pretty printed in the appropriate -style. All other text is simply echoed. -

Typical usage for LaTeX would be something like this (from the Makefile -used to produce this document): -

test7.tex: ../src/ott ../tests/test7.ott ../tests/test7tt.mng
-         cd ../src; make tmp_test7_clean.ott
-         ../src/ott                                        \
-                -i ../src/tmp_test7_clean.ott              \
-                -o test7.tex                               \
-                -tex_show_meta false                       \
-                -tex_wrap false                            \
-                -tex_name_prefix testSeven                 \
-                -tex_filter ../tests/test7tt.mng test7tt.tex 
-

The -tex_wrap false turns off output of the default LaTeX -document preamble, so the generated file test7.tex just contains -LaTeX definitions. -The -tex_name_prefix testSeven sets a prefix for the generated -LaTeX commands -(so the LaTeX definitions from multiple Ott source files can be -included in a single LaTeX document). -The -tex_filter argument takes two -filenames, a source and a destination. It filters the source file, -(roughly) replacing any string found within [[ ]] by -the tex pretty-print of its parse. This parsing is done w.r.t. the generated nonterminal -user_syntax which is a union of all the user’s grammar.

At present munged strings are not automatically -put within $ $, and there is no analogue of the -<[ ]> of our previous munger.

The lexing -turns any sequence of [ (resp. of ]) of -length n+1 for n>2 into a literal sequence of length n.

Figures 10 and 11 show a source file (test7tt.mng) that uses terms of the F<: -definition of test7.ott, and the result of filtering it.

Similar filtering can be performed on Coq, Isabelle, HOL, and OCaml files.

To filter files with respect to a relatively stable -system definition, without having to re-process the Ott source files of -that system definition each time, there are command-line options -

  -writesys <filename>                Output system definition
-  -readsys <filename>                 Input system definition
-

to first write the system definition (generated from some source files) to a file, and -then to read one back in (instead of re-reading the Ott source files). -The saved system definitions are in an internal format, produced using -the OCaml marshaller, and contain OCaml closures. They therefore will -not be compatible between different Ott versions. They may also be -quite large.


-
-We can TeX-typeset symbolic terms of the language, e.g.
-\[ [[ (\X<:Top. \x:X.x) [Top->Top] ]]\]
-and concrete terms
-\[ [[ :concrete: \Z1<:Top. \x:Z1.x ]]\]
-and similarly judgements etc, e.g.
-\[ [[G |- t : T ]] \]
-   
-Here is an extract of the syntax:
-
-\testSevengrammartabular{\testSevent\testSevenafterlastrule}
-
-and a single semantic rule:
-
-\[\testSevendruletinXXTwo{}\]
-
-and a judgement definition:
-
-\testSevendefnSA
-
-One can also include a ‘defns’ collection of judgements, or the complete definition.

9  Binding specifications

Our first example involved a production with a single binder: - -

specified by the source shown in Figure 4: -

-  | \ x . t      ::  :: Lam     (+ bind x in t +)
-

-in which a single variable binds in a single subterm. -Realistic programming languages often have much more complex binding -structures, e.g. structured patterns, multiple mutually recursive let definitions, -comprehensions, or-patterns, and dependent record patterns.

Ott has a flexible metalanguage for specifying binding structures, -expressive enough to cover these. -It comprises two forms of annotation on productions. -The first, - -lets one specify that variables bind in nonterminals of the -production, as in the Lam production above. -Here - -is a metavariable set expression, -e.g. in that lambda production just the singleton -metavariable - -of the production. -A variable can bind in multiple nonterminals, as in the example of -a simple recursive let below.

More complex examples require one to collect together sets of -variables. For example, the grammar below (shown in Ott source and the -generated LaTeX) has structured patterns, -with a -production in which all the binders of the pattern - -bind in the continuation - -

-t :: E_ ::=
-  | x                        ::   :: ident
-  | ( t1 , t2 )              ::   :: pair
-  | let p = t in t’          ::   :: letrec      (+ bind binders(p) in t’ +)
-
-
-p :: P_ ::=
-  | _                        ::   :: wildcard    (+ binders = {} +)
-  | x                        ::   :: ident       (+ binders = x +)
-  | ( p1 , p2 )              ::   :: pair        (+ binders = binders(p1) union binders(p2) +)
-

This is expressed with the second form of annotation: user-defined -auxiliary functions such as the -binders above. This is an auxiliary function defined over the - -grammar that identifies a set of variables to be -used in the bind annotation on the -production. There can be any number of such auxiliary functions; -binders is not a distinguished keyword.

The syntax of a precise fragment of the binding metalanguage is given in -Fig. 12, - -

where we have used Ott to define part of the Ott -metalanguage. A simple type system (not shown) enforces sanity properties, -e.g. that each auxiliary function is only applied to nonterminals that -it is defined over, and that metavariable set expressions are -well-sorted.

Further to that fragment, the tool supports binding for the list forms -of §12. -Metavariable set expressions can include lists of metavariables -and auxiliary functions applied to lists of nonterminals, e.g. as in -the record patterns below. -

This suffices to express the binding structure of almost all the -natural examples we have come across, including definitions of -mutually recursive functions with multiple clauses for each, Join -calculus definitions [FGL+96], dependent record patterns, and many others.

-

10  Generating substitution and free variable functions

The tool can generate Isabelle/Coq/HOL/OCaml code for both single and multiple -substitution functions. For example, the ML polymorphism Ott source -of test8.ott includes the following. -

-  substitutions
-    single   expr value_name :: subst  
-    multiple typexpr typvar  :: tsubst 
-

-This causes the generation of two families of substitution -functions, one replacing a single value_name by a expr, -the other replacing multiple typvars by typexprs.

Each family contains a function for each datatype for which it is -required, so in that example there are functions -subst_expr for the first and tsubst_typexpr, -tsubst_typscheme and tsubst_G for the second.

The functions for substitutions declared by -

-  substitutions
-    single   this that :: name1 
-    multiple this that :: name2 
-

-replaces terms of productions consisting just of a single that by a -this. -Here this must be a nonterminal root, while that can be -either a metavariable root or a nonterminal root (the latter -possibility allows substitution for compound identifiers, though it is -not clear that this is generally useful enough to be included). -Substitution functions are generated for each member of each (mutually recursive) -block of grammar rules which either contain such a production or (indirectly) -refer to one that does.

At present multiple substitutions are represented by Isabelle/Coq/HOL/OCaml -lists, so for the example above we have Isabelle -

  tsubst_typexpr :: "(typvar*typexpr) list => typexpr => typexpr"
-  tsubst_typscheme :: "(typvar*typexpr) list => typscheme => typscheme"
-  tsubst_G :: "(typvar*typexpr) list => G => G"
-

The generated functions do not substitute bound things, and recursive -calls under binders are filtered to remove the bound things.

Similarly, the tool can generate Isabelle/Coq/HOL/OCaml to calculate the free -variables of terms. For example, the ML polymorphism Ott source -of test8.ott includes the following. -

-  freevars
-    typexpr typvar :: ftv
-

-This causes Isabelle functions as below to be generated, calculating -the free typvars that occur in singleton productions in the -typexpr grammar, within terms of all types. -

  ftv_typexpr :: "typexpr => typvar list"
-  ftv_typscheme :: "typscheme => typvar list"
-  ftv_G :: "G => typvar list"
-
-

11  Locally-nameless representation

The Coq backend of Ott includes experimental support for a -locally-nameless representation (and co-finite quantification).

The user must specify which metavariables require a locally-nameless -representation via the repr-locally-nameless hom, -e.g.:

-metavar x ::= {{ repr-locally-nameless }} {{ com  term variable  }} 
-

As usual, metavariables can be bound in productions, using the -bindspec language, as in the lam production below: -

-grammar
-  t :: ’t_’ ::=                                         {{ com term }}
-    | x                   ::   :: Var                     {{ com variable }}         
-    | \ x . t             ::   :: Lam  (+ bind x in t +)  {{ com abstraction }}      
-    | t t’                ::   :: App                     {{ com application }}      
-    | ( t )               :: S :: paren   {{ coq [[t]] }} 
-    | { t / x } t’        :: M :: tsub    {{ coq (t_subst_t [[t]][[x  t’]]) }}
-

This definition gives rise to the datatype term below (here with option -coq_names_in_rules false): -

-Inductive term : Set := 
-| term_var_b : nat -> term 
-| term_var_f : var -> term 
-| term_lam : term -> term 
-| term_app : term -> term -> term.
-

Remarks: -

  1. -Productions containing metavariables susceptible to be bound -(e.g., term_var) give rise to two distinct constructors, one -(term_var_b) for de Bruijn indices to be used when the metavariable -is bound, one (term_var_f) for "free" variables. The type var, -together with decidable equality and several useful lemmas and -functions, is defined in the Metatheory library.

    In the current implementation, metavariables susceptible to be bound -in a symbolic term (eg. the x in the term_var -production) must be the only element of the production.

  2. Binder metavariables are erased from productions -(eg. term_lam), as in de Bruijn representation. -

Ott automatically generates the appropriate open functions -and lc predicates to test if terms are locally-closed. The -other support functions for substitutions and free-variables -(subst and fv) are generated once the user declares -the relevant substitutions and freevars sections.

Ott automatically compiles the symbolic terms that appear in rule -definitions into the appropriate terms in locally-nameless style. For -instance, the typing rule for the simply-typed lambda-calculus:

-    E,x:S |- t : T
-    ------------------ :: lambda
-    E |- \x.t : S->T
-

-is compiled into its locally-nameless representation: -

-Inductive typing : env -> term -> type -> Prop := (* defn typing *) 
-| ... 
-| typing_lambda : forall (L:vars) (E:env) (t:term) (S T:type), 
-   (forall x, x \notin L -> typing (E & x ~ S) (open_term_wrt_term t (term_var_f x)) T) -> 
-   typing E (term_lam t) (type_arrow S T).
-

For that, Ott follows the algorithm below. For each rule, -

  1. -for each nonterminal that appears in the rule, compute the -maximal set of binders under which it appears: for example, in the -rule lambda above, the maximal set of binders for the nonterminal t -is the singleton x, and it is empty for all the other nonterminals; -
  2. for each pair nonterminal / maximal binder set collected in -phase 1., go over all the occurrences of the nonterminal in the rule -and open them with respect to all the variables in the maximal -binding set except those under which this particular occurrence is -bound. In the example, this amounts to opening the occurrence of t -in the premise with respect to the metavariable x; -
  3. quantify using cofinite-quantification each metavariable that -has been used to open a nonterminal; -
  4. add hypothesis about local-closure to guarantee the invariant -that if a derivation holds, then the top-level terms involved are -locally-closed. -

-In some cases the user may want a finer control on which nonterminals -are opened and with respect to which metavariables. Consider for -instance the CBV beta-reduction rule: -

-    --------------------------  :: ax_app
-    (\x.t1) v2 –>  {v2/x}t1
-

-A naive application of the algorithm described above would open the -right hand side occurrence of t1 with respect to a -cofinitely-quantified x. Substitution should then be used to replace -the occurrences of x with v2, resulting in the awkward term -

-reduce (term_app (term_lam t1) v2) (subst_term v2 x (open_term_wrt_term t1 (term_var_f x)))
-

Instead, an idiomatic translation of CBV beta-reduction rule would -directly rely on the open function to substitute v2 for the -bound occurrences of x in t1, as in: -

-reduce (term_app (term_lam t1) v2) (open_term_wrt_term t1 v2)
-

A special syntax for production homomorphisms allow the user to specify this translation: -

-    | { t / x } t’        :: M :: tsub    {{ coq (t_subst_t [[t]][[x t’]]) }}
-

-In the homomorphism the nonterminal t’ is referred to with -[[x t’]] instead of the usual -[[t’]]: the prefixed x specifies -that occurrences of t’ should not be opened with respect to -the metavariable x. If this homomorphism is specified, then -the translation of the ax_app rule is exactly idiomatic Coq -shown above.

Current limitations: support for single binders only, no auxfn, Coq only.

Disclaimer: to compile rule definitions, Ott applies blindly the algorithm described above. Although in most of the cases, this generates a correct and idiomatic representation of the language, some language constructs might not be faithfully translated. Please, let us know if you find one of these cases. -

If Ott is invoked with the -coq_lngen option, then the -generated locally-nameless Coq code is compatible with Aydemir’s -lngen tool (http://www.cis.upenn.edu/ baydemir/papers/lngen/).

12  List forms

Ott has direct support for lists, both as dot forms such as - -and as list comprehensions such as - -. -Figure 13 shows an example semantic rule taken from our OCaml -fragment semantics, as both the generated LaTeX and its Ott -source, that involves several dot forms. -Other types commonly used in semantics, e.g. finite maps or sets, can -often be described with this list syntax in conjunction with type and -metaproduction homs to specify the proof assistant representation. -When using list forms, one usually also wants to add a list-of-formula -production to the formula grammar, e.g. (as in -test17.10.ott): -

-  formula :: formula_ ::=  
-   |  judgement                       ::   :: judgement
-   |  formula1 .. formulan            ::   :: dots
-

-The proof assistant code generation for such a production (which must -be named formula_dots) is special-cased to a list conjunction.


-
- E |- e1 : t1 ... E |- en : tn
- E |- field_name1 : t->t1 ... E |- field_namen : t->tn
- t = (t1’, ..., tl’) typeconstr_name
- E |- typeconstr_name gives typeconstr_name:kind {field_name1’; ...; field_namem’}
- field_name1...field_namen PERMUTES field_name1’...field_namem’
- length (e1)...(en)>=1
- ————————————————————————– :: record_constr
- E |- {field_name1=e1; ...; field_namen=en} : t

12.1  List dot forms

Example productions for -record types, record terms, and record -patterns are shown below, in both Ott source and LaTeX, taken -from our F<: example. -

-T, S, U :: ’T_’ ::=                                               {{ com type  }}
-  | { l1 : T1 , .. , ln : Tn }      :: :: Rec                       {{ com record }}           
-
-t :: ’t_’ ::=                                                     {{ com  term  }}
-  | { l1 = t1 ,  .. , ln = tn }     :: :: Rec                       {{ com record }}
-  | let p = t in t’                 :: :: Let (+ bind b(p) in t’ +) {{ com pattern binding}}
-
-p :: ’P_’ ::=                                                     {{ com  pattern }}
-  | x : T                           :: :: Var (+ b = x  +)          {{ com variable pattern }}
-  | { l1 = p1 , .. , ln = pn }      :: :: Rec (+ b = b(p1 .. pn) +) {{ com  record pattern  }}
-
-

-

Dot forms can be used in symbolic terms in semantic rules:

-

Individually indexed projections from dot forms can be mentioned, eg -the lj below:

-

Symbolic terms can also include concatenations of two dot forms with a -singleton in between:

-

Multiple dot forms within the same semantic rule can share bounds (e.g. 1..m):

-

In more detail, productions can have dot tokens interspersed between the elements. -Dot tokens consist of two, three or four consecutive dots (.., -..., or ....), indicating lists with minimum lengths 0, -1, and 2 respectively (these length minimums are respected -only when parsing concrete lists; they are not present in Isabelle/Coq/HOL -output). -The tool identifies the maximal sequence of elements on either side of -the dots that are identical modulo anti-unification of some -index. Optionally, there may also be a single terminal on either side -of the dot token, separating instances of the repeated unit. -For example, in the test7.ott production -

-  | { l1 = t1 ,  .. , ln = tn }  :: :: Rec                     
-

-there is such a terminal (the ‘,’). The tool identifies -that l1 = t1 and ln = tn can be anti-unified as -(roughly) l_ = t_, taking _ to be the bounds 1 and n. -A single production may contain multiple dot forms, but they must not overlap; -nested dot forms (including those with multiple changing indices) are not currently -supported.

Homomorphisms and binding specifications are generalised to match: an mse can -involve a dot form of metavariables; -a dot form of nonterminals; or an auxiliary function applied to a dot -form -of nonterminals (e.g. the -b(p1..pn) above). -Dot forms on the right of a bind are not currently supported.

LaTeX homomorphisms should not refer to dot forms, as either an error -or bad output will be generated. (For LaTeX, there should really be -some means to specify -a homomorphism for the repeated expression, and also data on how any -list separators should be typeset. This would require more -special-case treatment, which is not currently supported.)

-

12.2  List comprehension forms

Lists can also be expressed as explicit list comprehensions, -for more concise typesetting. -Three different styles are supported, with no bounds, an upper bound, -or a lower and upper bound. For example, in a symbolic -term, instead of the dot form -

-  G |- t1:T1  ..  G |- tn:Tn
- 

- -one can write any of the following -

-   </ G |- ti:Ti // i           />
-   </ G |- ti:Ti // i IN n      />
-   </ G |- ti:Ti // i IN 1 .. n />
- 

- -Similar comprehensions can be used in productions, for example lines -2–4 below. In addition, comprehensions in productions can specify a -terminal to be used as a separator in concrete lists, as in lines 5–7 below. -(These examples are taken from test17.10.ott.) -

-  |  l1 = t1 ,  .. , ln = tn            :: :: Rec              {{ com dots }}
-  |  </ li = ti // i           />       :: :: Rec_comp_none    {{ com comp }}
-  |  </ li = ti // i IN n      />       :: :: Rec_comp_u_none  {{ com compu }} 
-  |  </ li = ti // i IN 1 .. n />       :: :: Rec_comp_lu_none {{ com complu }}  
-  |  </ li = ti // , // i           />  :: :: Rec_comp_some    {{ com comp with terminal }}
-  |  </ li = ti // , // i IN n      />  :: :: Rec_comp_u_some  {{ com compu with terminal }} 
-  |  </ li = ti // , // i IN 1 .. n />  :: :: Rec_comp_lu_some {{ com complu with terminal }}  
- 

- -In Coq, HOL or Isabelle output, list dot forms and the -various list comprehension forms are treated almost identically. -In LaTeX output, comprension forms are default-typeset with overbars. -For example, the rules below -

- G|- t:l1:T1,..,ln:Tn
- ----------------------- :: Proj_dotform
- G|- t.lj : Tj
-
- G|- t:  </ li:Ti // i/> 
- ---------------------------------- :: Proj_comp
- G|- t.lj : Tj
-
- G|- t:  </ li:Ti // i IN n/> 
- ---------------------------------- :: Proj_comp_u
- G|- t.lj : Tj
-
- G|- t:  </ li:Ti // i IN 1..n/> 
- ---------------------------------- :: Proj_comp_lu
- G|- t.lj : Tj
- 

- -are typeset as follows.

-

Upper bounds of the form n−1 are also permitted, e.g. with -

- G|- t:l0:T0,..,ln-1:Tn-1
- ----------------------- :: Proj_dotform_minus
- G|- t.lj : Tj
-
- G|- t:  </ li:Ti // i IN 0..n-1/> 
- ---------------------------------- :: Proj_comp_lu_minus
- G|- t.lj : Tj
- 

- -typeset as below. More complex arithmetic expressions are not -currently supported.

-

A list form used in a symbolic term does not have to be in the same -style as that in the corresponding production. -However, if a metavariable or nonterminal occurs in multiple different -list forms in the same inference rule, they must all be in the same style and -with the same bounds. Moreover, in a production, a list form in a bindspec or -homomorphism must be in the same style and with the same bounds as the -corresponding list form in the elements of the production.

The comprehension form without an upper bound, -e.g. </ G |- ti:Ti // i />, -typeset as -is not standard -notation, but is often very useful. Many semantic rules involve lists -of matched length, e.g. of the -and -here, but do not need to introduce an -identifier for that length; omitting it keeps them concise.

The default visual style for typesetting list comprehensions can be -overridden by redefining the LaTeX commands \ottcomp, -\ottcompu, and \ottcomplu in an embed section, as -in Section 4.3.

In some cases one could make the typeset notation even less noisy, by -either omitting the superscript i or omitting both the superscript i and -the subscript i’s on t and T. The first is unambiguous if there -is at most one index on each element in the comprehension; the second -if all the elements are indexed by the same thing (not the case for -this example, but common for comprehensions of single elements, -e.g. << Ti // i>> for T). It is arguable that that -should be automated in future Ott releases, though it would bring the typeset and ASCII -versions out of step.

List comprehension forms can also be used in bindspecs and in -homomorphisms.

-

12.3  Proof assistant code for list forms

-

12.3.1  Types

-We have to choose proof assistant representations for productions involving list -forms. For example, for a language with records one might write -

-  metavar label, l ::= {{ hol string }} {{ coq nat }}
-  indexvar index, n ::=  {{ hol num }} {{ coq nat }} 
-  grammar
-  term, t :: ’t_’ ::=
-    | { l1 = t1 ,  .. , ln = tn }      :: :: record
-

- -In HOL and Isabelle we represent these simply with contructors whose -argument types involve proof-assistant native list types, e.g. -the HOL list of pairs of a label and a t: -

  val _ = Hol_datatype ` 
-  t = E_record of (label#t) list  `;
-

For Coq we provide two alternatives: one can either use -native lists, or lists can be translated away, depending on taste. -The choice is determined by the -coq_expand_list_types -command-line option. -In the former case we generate an appropriate induction principle -using nested fixpoints, as -the default principle produced by Coq is too weak to be useful. -In the latter case we -synthesise an additional type for each type of lists-of-tuples that -arises in the grammar. -In the example, we need a type of lists of -pairs of a label and a t: -

Inductive 
-list_label_t : Set := 
-   Nil_list_label_t : list_label_t
- | Cons_list_label_t : label -> t -> list_label_t 
-     -> list_label_t
-
-with t : Set := 
-   E_record : list_label_t -> t .
-

These are included in the grammar topological sort, and utility functions, e.g. to -make and unmake lists, are synthesised. -

-

12.3.2  Terms (in inductive definition rules)

-Supporting list forms in the rules of an inductive definition requires some additional analysis. For example, -consider the record typing rule below.

We analyse the symbolic terms in the premises and conclusion to -identify lists of nonterminals and metavariables with the same bounds — here t0 .. tn−1, T0 .. Tn−1, and l0 .. ln−1 -all have bounds 0..n−1. -To make the fact that they have the same length immediate in the -generated code, we introduce a single proof assistant -variable for each such collection, with appropriate projections and -list maps/foralls at the usage points. -For example, the HOL for the above is essentially as follows, with -an l_t_Typ_list : (label#t#Typ) list. -

(* Ty_Rcd *)  !(l_t_Typ_list:(label#t#Typ) list) (G:G) . 
-(EVERY (\b.b) 
-  (MAP (\(l_,t_,Typ_). (Ty G t_ Typ_)) l_t_Typ_list))
- ==> 
-(Ty 
-  G 
-  (E_record (MAP (\(l_,t_,Typ_). (l_,t_)) l_t_Typ_list))
-  (T_Rec    (MAP (\(l_,t_,Typ_). (l_,Typ_)) l_t_Typ_list)))
-

This seems to be a better idiom for later proof development than the -alternative of three different list variables coupled with assertions -that they have the same length.

With direct support for lists, we need also direct support for -symbolic terms involving list projection and concatenation. -For example, the rule -

gives rise to HOL code as below — note the list-lifted usage of the -is_v_of_t predicate, and the list appends (++) in the conclusion. -

(* reduce_Rec *)  !(l'_t'_list:(label#t) list) 
-       (l_v_list:(label#t) list) (l:label) (t:t) (t':t) . 
-((EVERY (\(l_,v_). is_v_of_t v_) l_v_list) /\
-(( reduce t t' )))
- ==> 
-(( reduce (t_Rec (l_v_list ++ [(l,t)] ++ l'_t'_list)) 
-          (t_Rec (l_v_list ++ [(l,t')] ++ l'_t'_list))))
-

For the Proj typing rule

we need a specific projection (the -HOL EL) to -pick out the j’th element: -

(* Ty_Proj *)  !(l_Typ_list:(label#Typ) list) 
-       (j:index) (G:G) (t:t) . 
-((( Ty G t (T_Rec (l_Typ_list)) )))
- ==> 
-(( Ty 
-     G 
-     (t_Proj t  ((\ (l_,Typ_) . l_) (EL j l_Typ_list)))  
-     ((\ (l_,Typ_) . Typ_) (EL  j l_Typ_list))))
-

For Coq, when translating away lists, we have to introduce -yet more list types for -these proof assistant variables, in addition to the obvious -translation of symbolic terms, and, more substantially, to introduce additional inductive relation -definitions to induct over them.

For similar examples in Isabelle, the generated Isabelle for the first -three rules of §12.1 is -shown below (lightly hand-edited for format). The first involves an -Isabelle variable l_t_T_list, and list maps and projections -thereof. -

Ty_RcdI: "
-  [|(formula_formuladots ((List.map (%(l_,t_,T_).( ( G , t_ , T_ ) : Ty)) l_t_T_list)))|] 
-  ==> 
-  ( G , 
-    (t_Rec ((List.map (%(l_,t_,T_).(l_,t_)) l_t_T_list))) , 
-    (T_Rec ((List.map (%(l_,t_,T_).(l_,T_)) l_t_T_list))) 
-  ) : Ty"
-
-Ty_ProjI: "
-  [| ( G , t , (T_Rec (l_T_list)) ) : Ty|] ==> 
-  ( G , 
-    (t_Proj t (%(l_,T_).l_) (List.nth l_T_list (j - 1))) , 
-    (%(l_,T_).T_) (List.nth l_T_list (j - 1)) 
-  ) : Ty"
-
-E_Ctx_recordI: "
-[| List.list_all (%(l_,v_).is_v v_) l_v_list ;
-   ( t , t' ) : E|] 
-==> 
- ( (t_Rec (l_v_list @ [(l,t)] @ l_'t_'list)) , 
-   (t_Rec (l_v_list @ [(l,t')] @ l_'t_'list)) 
- ) : E"
-

-The generated code for substitutions and free variables takes account of such list structure.

Note that at present the generated Isabelle code for these functions -does not always build without change, in particular if tuples of size -3 or more are required in patterns.

-

12.3.3  List forms in homomorphisms

Proof assistant homomorphisms in productions can refer to dot-form -metavariables and nonterminals. For example, the second production -below (taken from test17.9) mentions [[x1 t1 ... xn tn]] in the isa -homomorphism. This must exactly match the dot form in the production -except that all terminals must be omitted — the metavariables and -nonterminals must occur in the same order as in the production, and -the bounds must be the same.

-    E :: ’E_’ ::= {{ isa ( ident * t ) list  }}
-      | < x1 : t1 , .. , xn : tn > :: :: 2  {{ isa  List.rev [[x1 t1 .. xn tn]] }}
-    formula :: formula_ ::=          
-      | judgement              :: :: judgement
-      | formula1 .. formulan   :: :: dots
-

-The generated Isabelle code for symbolic -terms mentioning this production will involve a list of pairs. For -example, the rules -

-defn
-|- E  :: :: Eok :: Eok_ by
-
----------------------------- :: 2
-|- <x1:t1,..,xn:tn> 
-
-|- t1:K1  .. |- tn:Kn
----------------------------- :: 3
-|- <x1:t1,..,xn:tn> 
-

-generate -

consts
-  Eok :: "E set"
-inductive Eok tK
-intros
-
-(* defn Eok *)
-
-Eok_2I: " ( List.rev  (x_t_list) ) : Eok"
-
-Eok_3I: "[|
-(List.list_all (\<lambda> b . b) (  ((List.map (%(x_,t_,K_). ( t_ , K_ ) : tK) x_t_K_list))  ) )|]
- ==> 
- ( List.rev  ((List.map (%(x_,t_,K_).(x_,t_)) x_t_K_list)) ) : Eok"
- 

-Note that in the second the list of pairs is projected out from the -x_t_K_list list of triples that is quantified over in the rule.

-

13  Subrules

Subrule declarations have the form -

-  subrules
-    nt1 <:: nt2
-

-where nt1 and nt2 are nonterminal roots.

Subrules can be chained, i.e. there can be a pair of -subrule declarations nt1 <:: nt2 and nt2 <:: nt3, -and they can form a directed acyclic graph, e.g. with -nt0 <:: nt1, nt0 <:: nt2, -nt1 <:: nt3, and nt2 <:: nt3. However, there cannot be -cycles, or nonterminal roots for which there are multiple upper bounds. -Subrule declarations should not involve nonterminal roots for which -proof-assistant type homs are specified.

We support the case in which the upper rule is also -non-free, i.e. it contains productions that mention nonterminals that -occur on the left of a subrule declaration. In the example below -(test11.ott) the -t rule contains a production Foo v. -

-  metavar termvar , x ::=
-    {{ isa string }} {{ coq nat }} {{ coq-equality }} {{ hol string }} {{ ocaml int }}
-
-  grammar
-    t :: ’t_’ ::=                                         
-      | x                   ::   :: Var                   
-      | \ x . t             ::   :: Lam  (+ bind x in t +)
-      | t t’                ::   :: App                   
-      | Foo v               ::   :: Foo
-
-    v :: ’v_’ ::=                        
-      | \ x . t             ::   :: Lam

-      Baz t , v ::  :: Baz ::by 
-
-      
-      --------- :: ax
-      Baz t , v
-

- -In this case generated Isabelle/Coq/HOL/OCaml will define a single type and both is_v -and is_t predicates, and the generated inductive definition -clause for ax uses both predicates. The Isabelle clause is below. -

14  Context rules

The system supports the definition of single-hole contexts, e.g. for -evaluation contexts. For example, suppose one has a term grammar as below: -

-t :: ’t_’ ::=                               {{ com term    }}
-  | x                  ::  :: Var                   {{ com variable}}
-  | \ x . t            ::  :: Lam (+ bind x in t +) {{ com lambda  }}
-  | t t’               ::  :: App                   {{ com app     }}
-  | ( t1 , .... , tn ) ::  :: Tuple                 {{ com tuple }}
-  | ( t )              :: S:: Paren                 {{ icho [[t]]  }} 
-  | { t / x } t’       :: M:: Tsub  
-                        {{ icho (tsubst_t [[t]] [[x]] [[t’]])}}
-
-  | E . t              :: M:: Ctx  
-                        {{ icho (appctx_E_t [[E]] [[t]])}}
-                        {{ tex [[E]] \cdot [[t]] }}
-

-A context grammar is declared as a normal grammar but with a single -occurrence of the terminal __ in each production, e.g. as in -the grammar for E below (a rather strange evaluation -strategy, admittedly). -

-E :: ’E_’ ::=                               {{ com evaluation context }}
-  | __ t         ::  :: AppL                   {{ com app L    }}
-  | v __         ::  :: AppR                   {{ com app R    }}
-  | \ x . __     ::  :: Lam                    {{ com reduce under lambda }}
-  | ( t1 ( __  t2 ) ) :: :: Nested              {{ com hole nested }}
-  | ( v1 , .. , vm , __ , t1 , .. , tn ) :: :: Tuple {{ com tuple }}
-

-A contextrules declaration: -

-contextrules
-  E _:: t :: t
-

-causes Ott to (a) check that each production of the E grammar -is indeed a context for the t grammar, and (b) generates -proof assistant functions, e.g. appctx_E_t, to apply a context -to a term: -

(** context application *)
-Definition appctx_E_t (E5:E) (t_6:t) : t :=
-  match E5 with
-  | (E_AppL t5) => (t_App t_6 t5)
-  | (E_AppR v5) => (t_App v5 t_6)
-  | (E_Lam x) => (t_Lam x t_6)
-  | (E_Nested t1 t2) =>  (t_App t1  (t_App t_6 t2) )
-  | (E_Tuple v_list t_list) => (t_Tuple ((app_list_t v_list
-     (app_list_t (Cons_list_t t_6 Nil_list_t) (app_list_t t_list Nil_list_t)))))
-

As the Nested production shows, context productions can -involve nested term structure.

Note also that here the E grammar is not free (it mentions the -subrule nonterminal v) so an isvalue predicate -is_E_of_E is also generated.

In general, context rule declarations have the form -

-  contextrules
-    ntE _:: nt1 :: nt2
-

-where ntE, nt1, and nt2 are nonterminal -roots. This declares contexts ntE for the nt1 -grammar, with holes in nt2 positions.

Just as for substitutions, the context application function is -typically used by adding a metaproduction to the term grammar. -Here we add a production E.t to the t grammar with -an icho hom that uses appctx_E_t. -

-t :: ’t_’ ::=                               {{ com term    }}
-  ...
-  | E . t              :: M:: Ctx  
-                        {{ icho (appctx_E_t [[E]] [[t]])}}
-                        {{ tex [[E]] \cdot [[t]] }}
-

-That can then be used in relations: -

-    t –> t’
-    -------------- :: ctx
-    E.t –> E.t’
-

One would typically also define a terminals production for -the hole terminal __, e.g. here we typeset the hole as [·]. -

-terminals :: ’terminals_’ ::=
-  | __           ::  :: hole    {{ tex [\cdot] }}
-
-

15  Auxiliary Rules

-We permit an aux hom on grammar rules. For any rule with such a hom, -we transform that rule by appending an _aux to its primary nonterminal -root name. We then add a synthesised rule with the original nonterminal -root name and a single production, with a shape described by the body of -the aux hom, which must be of the form -

  {{ aux  foo1 foo2 _ bar1 bar2 bar3 }}
-

with a single _ and any number of strings fooi and barj before and -after. The _ is replaced by the original -nonterminal root name.

For example, given a grammar or metavariable l of source locations, one -might say -

ntr :: 'NTR_'  ::=  {{ aux _ l }}
- | ...
-

to synthesise grammars ntr_aux and ntr of unannotated and location-annotated -terms, the first with all the original productions and the second with a -single production -

 | ntr l :: :: NTR_aux. 
-

If the rule has an empty production name wrapper (eg with ’’ in place -of ’NTR_’) then the production name is based on the original -nonterminal root, capitalised and with _aux appended (eg Ntr_aux), to -avoid spurious conflicts.

An additional auxparams hom on rules lets the user add type -parameters to the generated OCaml output.

Generation of aux rules is controlled by a command-line option --generate_aux_rules, which one might (eg) set to false -for latex output and true for OCaml output.

-

16  Functions

Ott includes experimental support for writing function definitions. -As a simple example, consider the Ott file below:

-    grammar
-     n :: ’n_’ ::=
-       | 0       :: :: Zero
-       | S n     :: :: Succ
-
-    funs
-      Add ::=   {{ hol-proof ...  }}
-    fun
-      n1 + n2 :: n :: add    {{ com a function of type num -> num -> num }}
-    by
-      0 + n2 === n2
-      S n1 + n2 === n1 + S n2
-

Here the add function is compiled into the following Coq code:

-    Fixpoint add (x1:num) (x2:num) : num:=
-      match x1,x2 with
-      | n_zero , n2 => n2
-      | (n_succ n1) , n2 =>  (add n1 (n_succ n2) ) 
-    end.
-

More in detail, the -fun -n1 + n2 :: n :: add -by -declaration specifies: -

  • -the name of the function: add -
  • the symbolic term that defines the lhs: n1 + n2 -
  • the non-terminal that defines the rhs: n -

The type of the arguments of the function is defined by the -non-terminals appearing in the lhs, the return type by the rhs -non-terminal (so numnumnum in the -above example). As side-effect, whenever a function of type -symb_termnt is defined, a production -nt ::= symb_term is added to the definition of the -non-terminal nt (in the above example, the production -n1 + n2 is added to the grammar of num).

Functions are then defined by case analysis, where the lhs and the rhs -are separated by the reserved symbol ===.

The {{ hol-proof }} hom -allows the specification of a termination proof, which is required by -Hol. Mutually recursive functions can be defined in the same -funs block, analogously to mutually recursive rule -definitions.

Disclaimer: the different treatment of partial functions by the -different provers can result in a function definition being compiled -correctly to one prover but not to others.

-

17  Parsing Priorities

Symbolic terms that can have more than one parse tree are typically considered -erroneous; however, certain classes of parse trees are ignored in order to -support common idioms that are ambiguous. For example, the production -

-
Γ ::= Γ1, .., Γn

-might be used to allow a list of typing contexts to be appended together, but -it is highly ambiguous. The following restrictions forbid many unwanted parses -that could otherwise occur. -

  • -All parses in which a nonterminal derives itself without consuming any input -are ignored. For example, in the production above, the list could otherwise be -of length one so that Γ directly derives Γ giving rise to a -vacuous cycle, and an infinite forest of parse trees. This restriction -ensures that only the tree without the vacuous cycle is considered. -
  • The parser for a list form ignores parses that unnecessarily break up the list -due to (direct or indirect) self reference. For example, -Γ1234 will not parse as a two element sequence -of two element sequences (Γ12),(Γ34) given the -production above. -
  • User supplied priority annotations in a parsing section rule out certain -trees as follows: -
    • -prodname1 <= prodname2: Parse trees where a -prodname1 node is a child of a prodname2 node are -ignored. -
    • prodname1 right prodname2: Parse trees where a -prodname1 node is the leftmost child of a prodname1 -node are ignored. -
    • prodname1 left prodname2: Parse trees where a -prodname2 node is the rightmost child of a prodname1 -node are ignored. -
    -In addition to immediate children, these priority annotations also prohibit -parse trees where the forbidden child node occurs underneath a chain of -derivations from the specified parent when the chain does not consume any -input. -Figure 17 demonstrates a typical use of a parsing -section; the declarations have effect as follows: -
    • -Line #1: n + n + n parses as (n + n) + n, but not n + (n + n); -
    • Line #3: n + n - n parses as (n + n) - n, but not n + (n - n); -
    • Line #9: -n + n parses as (-n) + n, but not -(n + n); -
    • Line #15: n + n n parses as n + (n n), but not (n + n) n; -n n + n parses as (n n) + n, but not n (n + n); -
    • Line #20: n, n n, n parses as n, (n n), n, but not (n, n) (n, n). -
    -Currently, the parsing section supports only these relatively low level -and verbose declarations. -

18  Combining multiple source files

-Ott can be invoked with multiple source files. -Input filenames with extensions .tex, .v, -.thy, .sml, or ml are simply copied into -the relevant output (LATEX, Coq, Isabelle, HOL, or OCaml). -By default the source-file and command-line order of blocks is preserved, for grammar, -embeds, and inductive definitions.

The prover output can be split into multiple output files: each prover -output file specified with -o <filename> will contain the material -from the previous input files specified with -i (since the last -o -for the same prover).

Alternatively, one can add a -merge true command-line option, -in which case -the productions of multiple grammars that share the same header -are merged into a single grammar, and the rules of multiple -inductive definitions that share the same header are merged into a -single inductive definition. -This rudimentary form of modularity can be very useful, either to -split a language definition into separate features, or to define -reusable Ott components to define standard formulae, LaTeX pretty -printing of terminals, or LaTeX styles. -For example, Figure 15 shows the Ott source file for a -let feature in isolation, taken from our Ott development of -some languages from Pierce’s TAPL [Pie02]. -

-The original TAPL languages were produced using -TinkerType [LP03] to compose features and check for -conflicts. -In examples/tapl we build a system, similar to the TinkerType -sys-fullsimple, from ott source files that -correspond roughly to the various TinkerType components, each with -syntax and semantic rules for a single feature.

-

19  Hom blocks

-Bindspecs and homomorphisms for productions, and any homomorphisms -for definitions, can appear in an Ott source file either -attached to the production or definition, as we have shown earlier, or -in separate hom blocks. -For example, one can write -

-homs ’t_’
-  :: Lam  (+ bind x in t +)  
-
-homs ’t_’
-  :: Var     {{ com variable }}         
-  :: Lam     {{ com abstraction }}      
-  :: App     {{ com application }}      
-  :: paren   {{ ich [[t]] }} 
-  :: tsub    {{ ich ( tsubst_t [[t]] [[x]] [[t’]] ) }}
-
-homs ”
-  :: reduce  {{ com [[t1]] reduces to [[t2]] }} 
-

-Each of these begins with a prefix and then has a sequence of -production name or definition name kernels, each followed by a -sequence of bindspecs and then a sequence of homomorphisms.

The test10_homs.ott example, in Fig. 16, shows this. It -is semantically equivalent to the test10.ott example of -Fig. 8, but the homs have been moved into hom -blocks. -

20  Isabelle syntax support

Ott has limited facilities to allow the Isabelle mixfix syntax support -and xsymbol to be used. The example test10_isasyn.ott shows -this in use. -

Non-meta productions can be annotated with -isasyn and/or isaprec homomorphisms. -For example, test10_isasyn.ott contains the production -

-  | t t’      :: :: App   {{ isasyn [[t]]\<bullet>[[t’]] }}  {{ isaprec 50 }}
-

-The two homs are used to output the Isabelle syntax annotation in the -t_App clause of the datatype definition below. -

t = 
-   t_Var "termvar"  
- | t_Lam "termvar" "t"  ("\<lambda> _ . _" 60)
- | t_App "t" "t"  ("_\<bullet>_" 50)
-

-Definitions can be annotated with -isasyn and/or isaprec homomorphisms similarly, e.g. as below. -

-    defn
-    t1 –> t2 ::  :: reduce ::{{ isasyn [[t1]] —> [[t2]] }}  by 
-

-This generates syntax and translations blocks as below. -

inductive_set reduce :: "(t*t) set"
-and  "reduce'" :: "t => t =>  bool" ("_ ---> _" 50)
-where "(t1 ---> t2) ==  ( t1 , t2 ) : reduce"
-

-Symbolic terms in definitions are printed using any production or -definition syntax. This (especially with xsymbol turned on) makes the -current goal state during Isabelle proof development much more -readable.

Further, there is a command line option -isa_syntax true. If -this is set then the tool generates Isabelle syntax annotations from -the source syntax. For example, the source file production for the -t_Lam clause is -

-    | \ x . t             ::   :: Lam   {{ isaprec 60 }}
-

-and the terminals grammar contains a mapping from \ to \<lambda>: -

-  terminals :: ’terminals_’ ::=
-    | \                   ::   :: lambda  {{ tex \lambda }}  {{ isa \<lambda> }}
-    | –>                 ::   :: red     {{ tex \longrightarrow }} {{ isa —> }}
-

-This is used (just as for LaTeX homs) to generate the ("\<lambda> _ . _" 60) -in the datatype definition above.

This functionality is limited in various ways: -(1) the full range of Isabelle precedence and associativity -specifications are not supported; -(2) the automatically generated syntax annotations are somewhat crude, -especially w.r.t. spacing and parenthesisation; -(3) syntax annotation on meta productions is not propertly supported; -and -(4) it would be desirable to have more fine-grain control of whether -to automatically generate annotations: per-production, per-rule, and -per-file.

21  Isabelle code generation example

The Isabelle/Coq/HOL code generation facilities can be sometimes used to -generate (variously) OCaml and SML code from the Isabelle/Coq/HOL -definitions produced by Ott.

For example, the test10st_codegen.thy file uses Isabelle -code generation to produce SML code to calculate the possible -reductions of terms in the test10st.ott simply typed lambda -calculus.

theory test10st_codegen 
-imports test10st_snapshot_out Executable_Set
-begin
-
-ML "reset Codegen.quiet_mode"
-
-(* Code generation for the test10st simply typed lambda calculus. *)
-
-constdefs

-"ta == (t_App (t_Lam ''z'' (t_Var ''z''))) (t_Lam ''y'' (t_Var ''y''))"
-;
-
-code_module Test10st_codegen file "test10st_codegen.ml" contains 
-(*is_v

-reduce_ta  = "(ta,_):reduce"

-val it = t_Lam (["y"], t_Var ["y"]) : Test10st_codegen.t

22  Reference: Command-line usage

A good place to get started is one of the test -make targets in the ott directory, e.g. -

test10: tests/test10.ott
-           bin/ott                                                \
-                  -i tests/test10.ott                             \ 
-                  -o out.thy -o out.v -o outScript.sml            \
-                  -o out.tex                                      \
-                  -parse ":t:  (\z.z z) y"                        \                  
-           && ($(LATEX) out; $(DVIPS) out -o)
-

When make test10 is executed, ott: -

  • -reads the source file tests/test10.ott -
  • (if one also specifies -show_post_sort true and -show_defns -true) prints on standard output various diagnostic information, -including ASCII versions of the grammar and -inductive definitions. -By default these are coloured (using -vt220 control codes) with metavariables in red, nonterminals -in yellow, terminals in green, and object variables in white. -Scanning over this output quickly picks up some common errors. -
  • parses the symbolic term (\z.z z) y using the t -grammar and prints the result to standard output -
  • generates Isabelle definitions in the file out.thy -
  • generates Coq definitions in the file out.v -
  • generates HOL definitions in the file outScript.sml -
  • generates a LaTeX document in the file out.tex, with a -standard document preamble to make it self-contained. -

-That LaTeX document is then compiled and converted to postscript.

For convenience, input files can also be listed at the end of the command line: -

  ott [options] <file1> ... <filen>
-

is equivalent to -

  ott -i <file1> ... -i <filen> [options]
-

The %.out Makefile target runs ott with common -defaults on the file %.ott, so for example executing make tests/test10.out -runs ott on tests/test10.ott, generating all outputs. There are -also targets  %.coq.out,  %.hol.out, and - %.isa.out, to generate just LaTeX and the code for one proof -assistant, and  %.tex.out, to generate just LaTeX.

The ott command-line options (with default values where applicable) are -shown below. -

23  Reference: The language of symbolic terms

A syntax definition conceptually defines two different languages: that -of concrete terms of the object language, and that of symbolic terms -over the object language. -The former includes concrete variables (if nontrivial lex homs -have been specified for metavariables). -The latter includes the former but also -allows symbolic metavariables and nonterminals. -Symbolic terms may also include the production-name -annotations mentioned in §3. -For a syntax definition with list forms (c.f. §12) symbolic -terms also include various list constructs. -A simplified abstract syntax of symbolic terms is shown in -Figure 17, omitting list forms. In this section we give an -informal definition of the full concrete syntax of symbolic terms. -


-
-
Figure 17: Mini-Ott in Ott: symbolic terms
-

The premises and conclusions of inductive definition rules are -symbolic terms. -The language of symbolic terms is defined informally below, with interpretation functions [[_]] that map defined entities into grammar clauses.

For a rule rule   = -

-
nontermroot1   ,   ..   ,   nontermrootn ::   ’’   ::=   prod1   ..   prodm 

-we have -

-
- - - - -
 [[rule]]::= 
 |nontermroot suffix(1) 
 |[[prod1]] 
 |..  
 |[[prodm]] 

(1) for each nontermroot in the set -{nontermroot1   ,   ..   ,   -nontermrootn } -and for each nontermroot defined by any rule′ -which is declared as a subrule of this rule.

For a production prod   = -

-
|   element1   ..   elementm   ::   ::   prodname

-we have -

-
- - -
 [[prod]]::= 
 |[[element1]]   ..   [[elementm]] 
 |:prodname:  [[element1]]   ..   [[elementm]] 

For an element there are various cases. -

  1. -For a terminal terminal - -
    -
     [[terminal]]::=terminal
    -
  2. For a nonterminal nontermroot   suffix - -
    -
     [[nontermroot   suffix]]::=[[rule]] 
    -where rule includes nontermroot among the -nonterminal roots it defines. (Note that this does not depend on what suffix was used in the grammar, and similarly for the metavar case below.)
  3. For an index variable indexvarroot - -
    -
     [[indexvarroot]]::=indexvarroot
    -for each indexvarroot′ defined by the indexvar -definition that defines indexvarroot.
  4. For a metavariable metavarroot   suffix - -
    - - -
     [[metavarroot   suffix]]::= 
     |metavarroot′ suffix(1) 
     |variable 
    -(1) for each metavarroot′ defined by the metavar -definition that defines metavarroot. -(2) where variable ranges over all the strings defined by -the lex regexp of the metavar -definition that defines metavarroot, except for any string -which can be parsed as a nonterminal, metavariable or terminal of the syntax -definition. -
  5. A list form element element could be any of the following, either without a separating terminal: - -
    - - - - -
    element1 .. elementn  -  dots   -element1 .. elementn 
    </  element1 .. elementn   //   indexvar   /> 
    </  element1 .. elementn   //   indexvar   IN   indexvar′   /> 
    </  element1 .. elementn   //   indexvar   IN   number   dots   indexvar′   /> 
    </  element1 .. elementn   //   indexvar   IN   number   dots   indexvar-1   /> 
    -or with a separating terminal: - -
    - - - - -
    element1 .. elementn  -  terminal   dots   terminal   -element1 .. elementn 
    </  element1 .. elementn   //  terminal //  indexvar   /> 
    </  element1 .. elementn   //  terminal //  indexvar   IN   indexvar′   /> 
    </  element1 .. elementn   //  terminal //   indexvar   IN   number   dots   indexvar′   /> 
    </  element1 .. elementn   //  terminal //   indexvar   IN   number   dots   indexvar-1   /> 
    -In any of these cases the interpretation [[element]] is the lists (separated by the terminal if one was specified) of concrete list entries and of list forms. -Without a separating terminal, this is: - -
    - - - - - - - - - -
     [[element]]::=(concrete_list_entry | list_form)*(2), (3)
     
    concrete_list_entry::=[[element1]]   ..   [[elementn]] 
     
    list_form::= 
     |[[element1]]   ..   [[elementn]]  - dots′  -[[element1]]   ..   [[elementn]](1) 
     |</  [[element1]] .. [[elementn]]   //  indexvar″   /> 
     |</  [[element1]] .. [[elementn]] //  indexvar″   IN   indexvar‴   /> 
     |</  [[element1]] .. [[elementn]] //   indexvar″   IN   number′   dots′   indexvar‴   /> 
     |</  [[element1]] .. [[elementn]] //   indexvar″   IN   number′   dots′   indexvar-1   /> 
    -This is subject to constraints: (1) that -[[element1]]   ..   [[elementn]] -and -[[element1]]   ..   [[elementn]] can be -anti-unified with exactly one varying index; (2) if the list has only -concrete entries (i.e., no list forms), its length must meet -the constraint of any dots in the -element.

    With a separating terminal, we have: -

    -
    -
     [[element]]::=є | (concrete_list_entry | list_form) -(terminal (concrete_list_entry | list_form))*

In the above -

-
- - - - - - - - -
dots::=.. | ... | .... 
number::=0 | 1  
suffix::=suffix_item* 
suffix_item::= 
 |(0 | 1 |2 | 3 |4 | 5 |6 | 7 |8 | 9)+(longest match) 
 |_ 
 | 
 |indexvar 
 |indexvar-1 

Further, whitespace (' '|'\010'|'\009'|'\013'|'\012') is allowed before any token except a those in a suffix, and nonterminals, metavariables, index variables, and terminals that end with an alphanumeric character, must not be followed by an alphanumeric character.

The tool also builds a parser -for concrete terms, with fake nonterminal roots concrete_ntr -for each primary ntr of the syntax definition. One can -switch to concrete-term parsing with a :concrete: annotation, -as in the example -

\[ [[ :concrete: \Z1<:Top. \x:Z1.x ]]\]
-

-shown in Figure 10. Below such an annotation, only concrete terms -are permitted, with no further annotation, no symbolic nonterminals or -metavariables, no list dot forms or comprehensions, etc.

Parsing of terms is done with a scannerless GLR parser over character-list -inputs. The parser -searches for all parses of the input. If none are found, the ASCII -and TeX output are annotated no parses, with a copy of the -input with *** inserted at the point where the last token was -read. This is often at the point of the error (though if, for -example, a putative dot form is read but the two element lists cannot -be anti-unified, it will be after the point of the error). -If multiple parses are found, the TeX output is annotated -multiple parses and the different parses are output to the -console in detail during the Ott run.

The GLR parser -achieves reasonable performance on the small symbolic terms that are -typical in semantic rules. Its performance on large (whole-program -size) examples is untested.

24  Reference: Generation of proof assistant definitions

This section briefly summarises the steps involved in the generation -of proof assistant definitions from an Ott source file. For a description of the locally-nameless backend, refer to http://moscova.inria.fr/ zappa/projects/ln_ott/. -

-

24.1  Generation of types

  • -The primary metavariable roots and primary nonterminal roots are used -directly as the names of proof assistant types, except where they -have a hom specifying a root-overriding string. -
  • Type abbreviation declarations are produced for metavars, in the -source-file order, skipping metavars or nonterminals defined with phantom. -
  • Type generation considers each rule of the user’s source grammar -except those for formula and terminals (or the -synthesized rules for the syntax of judgements or user_syntax). -
  • The subrule order is analysed to identify the top elements. For -each of those, a proof assistant type will be generated — either a -free type (coq: inductive, isa: -datatype, hol: Hol_datatype), or if there is a -type hom for the proof assistant in question, a type abbreviation. -No types are generated for the non-top elements, as they will be -represented as predicates over the top free type above them. -
  • For the former, each non-meta production of the rule -gives rise to a constructor. The production name (with any per-rule -prefix already applied) is used directly as the constructor name. -The (curried) constructor argument types are taken from the -types associated with the metavariables and nonterminals mentioned -in the production body. -
  • Rules (within each grammar block, if -merge -false, or all rules, if -merge true) are topologically sorted according to the dependency order -(a free-type rule directly depends on another if one of its non-meta -productions includes a nonterminal of the other; dependencies for rules with a type-hom -for the proof assistant in question -are obtained from a crude lexing of the body of the type hom). -We then generate mutually recursive type -definitions for connected components, in an order consistent with -the dependencies. -
  • For productions that involve list dot forms or list comprehension -forms, for HOL and Isabelle we produce constructors with argument -types that involve native list types. For Coq, however, we -synthesise an additional inductive type for each list-of-tuples that arises -(both for those that occur in the grammar and for others required in -the translations of inductive definitions) and include them in the -topological sort. -
-

24.2  Generation of functions

-A small number of library functions (list_mem, -list_minus,...) are included in the output if they are -required.

Several Coq list functions (map, make, unmake, nth, app) are generated -for each synthesized list type.

The definitions of the more interesting functions (subrule predicates, -binding auxiliaries, free variable functions, and substitutions) are -generated over the free types generated for the maximal elements of the -subrule order (generation of these functions for rules with type homs -is not supported). The definitions are by pattern-matching and -recursion. -The patterns are generated by building canonical symbolic terms from -the productions of each relevant rule. -The recursion is essentially primitive recursion: -for Coq we produce Fixpoints or Definitions -(the latter is sometimes needed as the former gives an error in the case where there is no -recursion); -for Isabelle we produce primrecs (or, experimentally, funs); -for HOL we use an ottDefine variant of the Define -package. -In general we have to deal both with the type dependency -(the topologically sorted mutually recursive types described above) -and with function dependency — for example, for subrule predicates -and binding auxiliaries we may have multiple mutually recursive -functions over the same type.

For Coq the function generation over productions that involve list -types must mirror that, so we generate auxiliary functions -that recurse over those list types.

For Isabelle the primrec package does not support -definitions involving several mutually recursive functions over the -same type, so for these we generate single functions calculating -tuples of results, define the intended functions as projections of -these, and generate lemmas (and simple proof scripts) characterising -them in terms of the intended definitions. -Further, it does not support pattern matching involving nested -constructors. We therefore generate auxiliary functions for -productions with embedded list types. Isabelle tuples are treated as -iterated pairs, so we do the same for productions with tuples of size -3 or more. -Isabelle also requires a function definition for each recursive type. -In the case where there are multiple uses of the same type -(e.g. several uses of t list in different productions) all the -functions we wish to generate need identical auxiliaries. As yet, the -tool does not generate the identical copies required.

If the option -isabelle_primrec is set to false, then -Ott uses the fun package instead of the primrec package. -Since at the time of writing Isabelle 2008 is not capable of proving -automatically termination of all the funs that Ott generates, -this feature should be considered experimental.

For HOL the standard Define package tries an automatic -termination proof. For productions that involve list types -our generated functions involve various list functions which prevent -those proofs working in all cases. -We therefore use an ottDefine variant (due to Scott Owens), -with slightly stronger support for proving termination of -definitions involving list operators.

-

24.2.1  Subrule predicates

We generate subrule predicates to carve out the subsets of each free -proof assistant type (from the maximal elements of the subrule order) -that represent the rules of the grammar. -The non-free rules are the least subset of the rules that either -(1) occur on the left of a subrule (<::) declaration, or -(2) have a (non-meta) production that mentions a non-free rule. -Note that these can include rules that are maximal elements of the -subrule order, e.g. if an expression grammar included a production -involving packaged values. -The subrule predicate for a type is defined by pattern matching over -constructors of the maximal type above it — for each non-meta -production of the maximal type it calculates a disjunction -over all the productions of the lower type that are subproductions of -it, invoking other subrule predicates as appropriate.

-

24.2.2  Binding auxiliaries

-The binding auxiliary functions calculate the intuitive semantics of auxiliary functions defined in bindspecs of the Ott source file. Currently these are represented as proof assistant lists of metavariables or nonterminals (arguably set types should be used instead, at least in Isabelle).

-

24.2.3  Free variables

-The free variable functions simply walk over the structure of the free proof assistant types, using any bind specifications (and binding auxiliaries) as appropriate. -For these, and for substitutions, we simplify the generated functions by using the dependency analysis of the syntax to exclude recursive calls where there is no dependency.

-

24.2.4  Substitutions

-The generated substitution functions also walk over the structure of the free proof assistant types. -For each production, for each occurrence of a nonterminal nt within it, we first calculate the things (of whatever type is in question) binding in that nt, i.e. those that should be removed from the domain of any substitution pushed down into it. There are two cases: -(1) the mse' from any bind mse' in nt; -(2) nt itself if it occurs in the mse'' of any bind mse'' in nt'', i.e.  -nt itself if it is directly used to bind elsewhere. -List forms within bindspecs are dealt with analogously. -

The substitution function clause for a production is then of one of two forms: -either (1) the production comprises a single element, of the nonterminal or metavariable that we are substituting for, and this is within the rule of the nonterminal that it is being replaced by, or (2) all other cases. -For (1) the element is compared with the domain of the substitution, and replaced by the corresponding value from the range if it is found. -For (2) the substitution functions are mapped over the subelements, having first removed any bound things from the domain of the substitution.

This is all done similarly, but with differences in detail, for single and for multiple substitutions.

-

24.3  Generation of relations

-The semantic relations are defined -with the proof-assistant inductive relations packages -(coq: Inductive, -isa: inductive, -hol: Hol_reln). -They use the mutual recursion structure that is given by the user, -with each defns block giving rise to a potentially mutually -recursive definition of each defn inside it. -(It is debatable whether it would be preferable to do an automatic dependency analysis and topological sort, as for the syntax.) -Each definition rule gives rise to an implicational clause, essentially -that the premises (Ott formulas) imply the conclusion (an Ott symbolic term of whichever judgement is being defined). -In addition: -

  • -Symbolic terms are transformed in various different ways: -
    • -Nodes of non-meta productions are output as applications of the appropriate proof-assistant constructor (and, for a subrule, promoted to the corresponding constructor of a maximal rule). -
    • Nodes of meta productions are transformed with the user-specified homomorphism. -
    • Nodes of judgement forms are represented as applications of the defined relation in Coq and HOL, and as set-membership assertions in Isabelle. -
    • Lists of formulae (the formula_dots production) are special-cased. -
    -
  • For each nonterminal of a non-free syntax rule (as in §24.2.1) that occurs, -e.g. a usage of v' where v<::t, an additional premise invoking the subrule predicate for the non-free rule is added, e.g. is_v v'. -
  • The set of symbolic terms of the definition rule are analysed together to identify list forms with the same bounds. A single proof assistant variable is introduced for each such, with appropriate projections and list maps/foralls at the usage points. -
  • For Coq, auxiliary defined relations are introduced for list forms. -
  • For Coq, as the projections from list forms involve (Ott-generated) nth functions that return option types, for any such projection a pattern-match against Some is introduced as an additional premise. -
  • For Coq and HOL, explicit quantifiers are introduced for all variables mentioned in the rule. -
-

26  Reference: The Ott source grammar

-This is automatically generated (by mly-y2l) from the -ocamlyacc grammar for Ott. -

The lexing of Ott source files is context-dependent; this does not -show that.

Not everything in the grammar is fully supported — in particular, -option element forms, non-dotted element list forms, the three names distinctness forms of -bindspecs, and context rules.

-

27  Reference: Examples

The project web page -

-http://www.cl.cam.ac.uk/users/pes20/ott/ -

-gives a variety of examples. Some of these, and additional -small examples, are included in the distribution in the tests -directory. Typically they can be built using the Makefile in -the ott directory, e.g. typing make test10 or (more generally) make tests/test10.out) there.

-Ott is a tool for writing definitions of programming languages and -calculi. It takes as input a definition of a language syntax and -semantics, in a concise and readable ASCII notation that is close to -what one would write in informal mathematics. It generates LaTeX to -build a typeset version of the definition, and Coq, HOL, and Isabelle -versions of the definition. Additionally, it can be run as a filter, -taking a LaTeX/Coq/Isabelle/HOL source file with embedded (symbolic) -terms of the defined language, parsing them and replacing them by -target-system terms. -For a simple example, here is an -Ott source file for an untyped call-by-value -lambda calculus (test10.ott), and -the generated -LaTeX (compiled to pdf) -and (compiled to ps), -Coq, -Isabelle, and -HOL -definitions. -

-Most simply, the tool can be used to aid completely informal LaTeX mathematics. -Here it permits the definition, and terms within proofs and -exposition, to be written in a clear, editable, ASCII notation, without LaTeX -noise. It generates good-quality typeset output. -By parsing (and so sort-checking) this input, it quickly catches a -range of simple errors, e.g. inconsistent use of judgement forms or -metavariable naming conventions. -

-That same input can be used to generate formal definitions, for Coq, -HOL, Isabelle, and (experimentally) Lem. It should thereby enable a smooth transition -between use of informal and formal mathematics. Additionally, the -tool can automatically generate definitions of functions for free -variables, single and multiple substitutions, subgrammar checks -(e.g. for value subgrammars), and binding auxiliary functions. -At present only a fully concrete representation of binding, without -quotienting by alpha equivalence, is fully supported. An experimental -backend generates a locally-nameless representation of terms for a -subset of the Ott metalanguage: details can be -found here. -

-The distribution includes several examples, in varying levels of completeness: -untyped and simply typed lambda-calculus, -a calculus with ML polymorphism, -the POPLmark Fsub with and without records, -an ML module system taken from (Leroy, JFP 1996) and equipped with an -operational semantics, and -LJ, a lightweight Java fragment. -More substantially, Ott has been used for work on -iJAM and LJAM, Java Module - Systems, by Rok - Strniša, and semantics for -OCaml light, by - Scott Owens. -

-A release of the Ott source is available, and comment and -feedback would be much appreciated. -

It is impure: - name generation is an observable side effect. In practice, this means that - FreshML allows writing programs that create fresh names and unintentionally - fail to bind them. Following in the steps of early work by Pitts and Gabbay, - this paper defines Pure FreshML, a subset of FreshML equipped with a static - proof system that guarantees purity. Pure FreshML relies on a rich binding - specification language, on user-provided assertions, expressed in a logic that - allows reasoning about values and about the names that they contain, and on a - conservative, automatic decision procedure for this logic. It is argued that - Pure FreshML can express non-trivial syntax-manipulating algorithms.} -} - -@MISC{Chargueraud06, - author = {Arthur Chargu\'eraud and Benjamin C.

It generates output: -\begin{enumerate} -\item a \myLaTeX{} source file that defines commands to build a typeset version of - the definition; -\item a Coq version of the definition; -\item a HOL version of the definition; -\item an Isabelle/HOL version of the definition; -\item a Lem version of the definition; -\item an OCaml version of the syntax of the definition. -\end{enumerate} -Additionally, it can be run as a filter, taking a -\myLaTeX{}/Coq/Isabelle/HOL/Lem/OCaml source file -with embedded (symbolic) terms of the defined language, parsing them and replacing -them by typeset terms. - - -This document is a user guide for the tool.

The project web page -\begin{quotation} -\ahrefurl{http://www.cl.cam.ac.uk/users/pes20/ott/} -\end{quotation} -links to the github source repository, with a -BSD-style licence. It also has a range of examples, including -untyped and simply typed CBV lambda calculus, ML polymorphism, various -first-order systems from Pierce's TAPL~\cite{Pierce:TypeSystems}, the -POPLmark F$_{<:}$ language~\cite{poplmark}, a module system by -Leroy~\cite[\S4]{Leroy-generativity} (extended with a term language and an -operational semantics), the LJ Java fragment and LJAM Java module -system~\cite{ljam-sub}, and a substantial fragment of OCaml. - - - -Our main goal is to support work on large programming language -definitions, where the scale makes it hard to keep a definition -internally consistent, and hard to keep a tight correspondence between a -definition and implementations. -% -We also wish to ease rapid prototyping work with smaller calculi, -and to make it easier to exchange definitions and definition fragments -between groups. -% -% -Most simply, the tool can be used to aid completely informal \myLaTeX{} mathematics. -Here it permits the definition, and terms within proofs and -exposition, to be written in a clear, editable, ASCII notation, without \myLaTeX{} -noise. It generates good-quality typeset output. -By parsing (and so sort-checking) this input, it quickly catches a -range of simple errors, e.g.~inconsistent use of judgement forms or -metavariable naming conventions. -% -That same input, extended with some additional data, can be used to generate formal definitions for -Coq, HOL, Isabelle, and Lem. It should thereby enable a smooth transition -between use of informal and formal mathematics. Further, the -tool can automatically generate definitions of functions for free -variables, single and multiple substitutions, subgrammar checks -(e.g.~for value subgrammars), and binding auxiliary functions. -Ott supports a `fully concrete' representation, sufficient -for many examples but not dealing with general alpha equivalence. -An experimental Coq backend generates definitions in locally-nameless style for a subset of the Ott metalanguage. - The OCaml backend -generates type definitions that may be useful for developing a complete -implementation of the language, together with the functions listed -above. It does not generate anything for inductively defined relations -(the various proof-assistant code extraction facilities can -sometimes be used for that). -% -Our focus here is on the problem of writing and editing language -definitions, not (directly) on aiding mechanized proof of metatheory. If one -is involved in hard proofs about a relatively stable small calculus -then it will aid only a small part of the work (and one might choose -instead to work just within a single proof assistant), but for larger -languages the definition is a more substantial problem --- so much so -that only a handful of full-scale languages have been given complete definitions. We -aim to make this more commonplace, less of a heroic task. - -% getting started with Ott -\input{README} - - -\section{A minimal Ott source file: the untyped CBV lambda calculus}\mlabel{a51}% -Fig.~\ref{a45} shows an Ott source file for an untyped call-by-value -(CBV) lambda calculus. This section explains the basic features that -appear there, while in the following sections we show what must be -added to generate typeset output, proof assistant definitions, and -other things. -\begin{figure} -\fbox{\small\begin{minipage}{\textwidth} -\input{test10.0.alltt} -\end{minipage}} -\caption{Source: \texttt{test10.0.ott}\protect\label{a45}} -\end{figure} -The figure is colourised, with Ott keywords like \mykw{this} and Ott -symbols such as \mysym{|} and \mysym{::}. Other user-specific input -appears like \texttt{this}. - -At the top of the figure, the \mykw{metavar} declaration introduces -a sort of \emph{metavariables} \texttt{termvar} (with synonym \texttt{x}), for term -variables. -% -The following \mykw{grammar} introduces two grammar rules, one for terms, with - \emph{nonterminal root} - \texttt{t}, and one for values \texttt{v}. -This specifies the concrete syntax of object-language terms, -the abstract syntax representations for proof-assistant mathematics, -and the syntax of symbolic terms to be used in semantic rules. - -Each rule has a rule name prefix (e.g.~\texttt{'t\_'}) and then a list -of productions. Each production, e.g. -\begin{alltt} - \mysym{|} \mybackslash{} x . t \mysym{::} \mysym{::} Lam -\end{alltt} -specifies a syntactic form as a list of elements, here `\verb+\+', -`\verb+x+', `\verb+.+', and `\verb+t+', each of which is either a -metavariable (the `\verb+x+'), a nonterminal (the `\verb+t+'), or a -terminal -(\texttt{\mybackslash} \texttt{.} \texttt{(} \texttt{)} \texttt{\mylb} \texttt{\myrb} \texttt{/} \texttt{-->}). -% -Within productions all elements must be whitespace-separated, so that -the tool can deduce which are terminals. In the symbolic terms in -the semantic rules below, however, whitespace is required only where necessary. -%Terminals are not required to be declared in the \texttt{terminals} -%grammar (all strings that are not metavariables or nonterminals are -%regarded as terminals) but, if they are, then \myLaTeX{} pretty printing -%information for them can be specified there. In this example the -%`\verb+\+' is included in the \texttt{terminals} grammar and will be -%\myLaTeX pretty printed as a $\lambda$, whereas the `\verb+.+' is not -%included and will be pretty printed in a default form. -A few terminals have to be quoted (with \verb+''+) if they appear in a grammar, e.g. to -use \texttt{|} as an object-language token, as they are part of the Ott syntax, but they -do not have to be quoted at usage points. -% -(If one accidentally omits inter-token whitespace in the grammar, the -output of Ott can be surprising. This is best diagnosed by looking at -the colourised ASCII or \myLaTeX{} output from Ott.) - -Metavariables and nonterminals can be formed from the specified -metavariable and nonterminal roots by appending a suffix, e.g.~the -nonterminal \verb+t'+ in the \verb+App+ and \verb+Tsub+ productions. - - - - -Between the \mysym{::}'s is an optional meta flag \mykw{M} or \mykw{S}. Non-meta -productions give rise to clauses of datatype definitions in the -Isabelle/Coq/HOL output, whereas meta productions do not. Later, we -will see how the user can specify how meta syntax should be translated -away when generating proof assistant output. The two flags \mykw{M} -and \mykw{S} are identical except that productions with the latter are -admitted when parsing example concrete terms; the \mykw{S} tag is thus -appropriate for lightweight syntactic sugar, such as productions for -parentheses. One can also use an \mykw{X} flag here to suppress a -production in the generated LaTeX. - -Each production has a production name (e.g.~\verb+t_Lam+), composed of -the rule name prefix (here~\verb+t_+) and the production name kernel -that follows the \mysym{::}'s (here~\verb+Lam+). The production name is -used as a constructor name in the generated Isabelle/Coq/HOL. - -The tool supports arbitrary context-free grammars, extended with -special constructs for list forms (c.f.~\S\mref{a61}). - - -Following the \mykw{grammar} in this example is a \mykw{subrule} -declaration -\begin{alltt} - \mykw{subrules} - v \mysym{<::} t -\end{alltt} -declaring that the \verb+v+ grammar rule (of values) is a -subgrammar of the \verb+t+ rule (of terms). The tool checks that -there is in fact a subgrammar relationship, i.e.~that for each -production of the lower rule there exists a production of the higher -rule with corresponding elements (up to the subrule relation). -The subrule declaration means that, in the semantic rules below, we -will be able to use \verb+v+'s in places where the grammar specifies \verb+t+'s. -In the generated Isabelle/Coq/HOL for this example only one free -datatype will be generated, for the \verb+t+ rule, while for the \verb+v+ -rule we generate an \verb+is_v+ predicate over the \verb+t+ type. Usages of -\verb+v+ nonterminals in the semantic rules will have instances of this -predicate automatically inserted. - -Finally, we give a collection of definitions of inductive relations. -In this example there is just one family of definitions (of -operational judgements), introduced by the \mykw{defns} \verb+Jop+; it contains just one -definition of a relation, called \verb+reduce+. -In general there may be many \mykw{defns} blocks, each of which introduces a -mutually recursive collection of \mykw{defn}s. -The relation definition -\mykw{defn}\verb+ ...+ -also includes a grammar production specifying how elements of the -relation can be written and typeset, here -\begin{verbatim} - t1 --> t2 -\end{verbatim} -As in the main grammar, the tokens of this syntax definition in the -header must be space-separated, but usages of the syntax generally -need not be. -Syntax rules for each family of -judgements, and for their union, are implicitly generated. -The relation definition is given by a sequence of inference rules, -each with a horizontal line separating a number of premises from a -conclusion, for example as below. -\begin{alltt} - t1 --> t1' -\mysym{ -------------- ::} ctx_app_arg - v t1 --> v t1' -\end{alltt} -The conclusion must be a symbolic term of the form of the judgement being -defined. -In simple cases (as here) the premises can be symbolic terms of the -form of any of the defined judgements. More generally (see -\S\ref{a53}) they can be symbolic terms of a user-defined -\mykw{formula} grammar, or in-line embedded prover code. -Each rule - has a name, composed of a definition family prefix -(here empty), a definition prefix (here also empty) and a kernel -(the~\verb+ctx_app_arg+). -% - - - - -The symbolic terms in semantic rules are parsed with a scannerless parser, built -using parser combinators over character-list inputs. The parser -searches for all parses of the input. If none are found, the ASCII -and TeX output are annotated \texttt{no parses}, with a copy of the -input with \texttt{***} inserted at the point where the last token was -read. This is often at the point of the error (though if, for -example, a putative dot form is read but the two element lists cannot -be anti-unified, it will be after the point of the error). -If multiple parses are found, the TeX output is annotated -\texttt{multiple parses} and the different parses are output to the -console in detail during the Ott run. -% -If the option \texttt{picky\_multiple\_parses} is set to -\texttt{true}, multiple parses are always reported. If it set to -\texttt{false}, a symbolic term is considered ambiguous only if two -different parses compile to different strings (for a target). -% -The parser combinators use memoization and continuation-passing to -achieve reasonable performance on the small symbolic terms that are -typical in semantic rules. Their performance on large (whole-program -size) examples is untested. -% -To resolve ambiguity one can add metaproductions for parentheses (as -in Fig.~\mref{a45}), or -production-name annotations in particular symbolic terms, -e.g.~the \verb+:t_tsub:+ in the \verb+AppAbs+ rule of the POPLmark -example, -\texttt{test7.ott}. %\S\mref{a27}. - There is currently no support for precedence -or associativity. - - -This file is included in the distribution as -\texttt{tests/test10.0.ott}.

It is possible to turn off the generation of definitions for -these such functions by writing the following directive early on in the source file: - -\begin{alltt} -\mykw{embed} \mysym{\mylb\mylb{}} \mykw{coq-lib} list_mem list_minus \mysym{\myrb\myrb{}} -\end{alltt} - -This instructs Ott to avoid generating definition for \verb+list_mem+ and -\verb+list_minus+, but to continue generating definitions for other functions -such as \verb+list_assoc+ and \verb+list_minus2+. - -\textbf{Note about }\verb+list_minus2+\textbf{:} -Instead of using the function \verb+list_minus2+, earlier versions of Ott -generated equivalent code based on \verb+list_filter+, which was more -difficult to reason about. For backwards compatibility, however, we provide the -command-line option \verb+-coq_use_filter_fn+ for generating a definition using -the older code pattern. - -\subsection{Correctness of the generated proof assistant code} -We have attempted to ensure that the proof assistant definitions -generated by Ott are well-formed and what the user would intend. This -is not guaranteed, however, for several reasons: (1) There may be name -clashes between Ott-generated identifiers and proof assistant built-in -identifiers (or, in pathological cases, even among different -Ott-generated identifiers). (2) In some cases we depend on automatic -proof procedures, e.g.~for HOL definitions. These work in our test -cases, but it is hard to ensure that they will in all cases. More -importantly, (3) the generation process is complex, so it is quite -possible that there is either a bug in Ott or a mismatch between the -user expectation and what the tool actually does. Ultimately one has -to read the generated proof assistant definitions to check that they -are as intended --- but typically one would do this in any case, many -times over, in the process of proving metatheoretic results, so we do -not consider it a major issue. - -\subsection{Using the generated proof assistant code} -% -Note added 2017-11-30: the following is out of date. - -Ott builds code for - -\begin{tabular}{ll} -Coq 8.3 & \ahrefurl{http://coq.inria.fr/} \\ -HOL 4 (the current svn version) & \ahrefurl{http://hol.sourceforge.net/}\\ -Isabelle/HOL (Isabelle 2011) & \ahrefurl{http://isabelle.in.tum.de/} -\end{tabular} - -Given proof assistant files in the top-level directory of the -distribution, as produced at the start of this section -(Coq \texttt{out.v}, Isabelle \texttt{out.thy}, and HOL -\texttt{outScript.sml}), the various proof assistants can be invoked as follows. - -\subsubsection{Coq} -First run -\begin{verbatim} - make -\end{verbatim} -in the \texttt{coq} directory of the distribution, to build the auxiliary files. -These include a core file (\verb+ott_list_core+) of definitions that -are used in Ott-generated output. -At present these are only required when Coq native lists are used. -There are also various lemmas (in -\verb+ott_list.v+) which may be useful; they can be made available with -\verb+Require Import ott_list.+ - -For batch mode run -\begin{verbatim} - coqc -I coq out.v -\end{verbatim} -where \verb+coq+ is the path to the \verb+coq+ directory of the distribution. - -The experimental locally-nameless backend requires the \verb+Metatheory+ library by Arthur Chargueraud, available from the project web page. - -\subsubsection{HOL} -First run -\begin{verbatim} - Holmake -\end{verbatim} -in the \texttt{hol} directory of the distribution, to build the auxiliary files. - - For -batch mode run -\begin{verbatim} - Holmake -I hol outTheory.uo -\end{verbatim} -% -where \verb+hol+ is the path to the \verb+hol+ directory of the distribution. -% -For interactive mode, run -\begin{verbatim} - hol -I hol -\end{verbatim} -inside an editor window (where the second \verb+hol+ is again the path -to the \verb+hol+ directory of the distribution), and in -another window view the \verb+outScript.sml+ file.

For each rule, -\begin{enumerate} -\item for each nonterminal that appears in the rule, compute the - maximal set of binders under which it appears: for example, in the - rule lambda above, the maximal set of binders for the nonterminal \texttt{t} - is the singleton \texttt{x}, and it is empty for all the other nonterminals; -\item for each pair nonterminal / maximal binder set collected in - phase 1., go over all the occurrences of the nonterminal in the rule - and open them with respect to all the variables in the maximal - binding set except those under which this particular occurrence is - bound. In the example, this amounts to opening the occurrence of \texttt{t} - in the premise with respect to the metavariable \texttt{x}; -\item quantify using cofinite-quantification each metavariable that - has been used to open a nonterminal; -\item add hypothesis about local-closure to guarantee the invariant - that if a derivation holds, then the top-level terms involved are - locally-closed. -\end{enumerate} -In some cases the user may want a finer control on which nonterminals -are opened and with respect to which metavariables.

The following restrictions forbid many unwanted parses -that could otherwise occur. -% -\begin{itemize} -\item -All parses in which a nonterminal derives itself without consuming any input -are ignored. For example, in the production above, the list could otherwise be -of length one so that $\Gamma$ directly derives $\Gamma$ giving rise to a -vacuous cycle, and an infinite forest of parse trees. This restriction -ensures that only the tree without the vacuous cycle is considered. -\item -The parser for a list form ignores parses that unnecessarily break up the list -due to (direct or indirect) self reference. For example, -$\Gamma_1,\Gamma_2,\Gamma_3,\Gamma_4$ will not parse as a two element sequence -of two element sequences $(\Gamma_1,\Gamma_2),(\Gamma_3,\Gamma_4)$ given the -production above. -\item -%\textit{\large Experimental Feature:} -User supplied priority annotations in a \mykw{parsing} section rule out certain -trees as follows: -\begin{itemize} -\item -$\mathit{prodname}_1 \mysym{<=} \mathit{prodname}_2$: Parse trees where a -$\mathit{prodname}_1$ node is a child of a $\mathit{prodname}_2$ node are -ignored. -\item -$\mathit{prodname}_1~\mykw{right}~\mathit{prodname}_2$: Parse trees where a -$\mathit{prodname}_1$ node is the leftmost child of a $\mathit{prodname}_1$ -node are ignored. -\item -$\mathit{prodname}_1~\mykw{left}~\mathit{prodname}_2$: Parse trees where a -$\mathit{prodname}_2$ node is the rightmost child of a $\mathit{prodname}_1$ -node are ignored. -\end{itemize} -In addition to immediate children, these priority annotations also prohibit -parse trees where the forbidden child node occurs underneath a chain of -derivations from the specified parent when the chain does not consume any -input. -Figure~\ref{parsing_figure} demonstrates a typical use of a \mykw{parsing} -section;

For a description of the locally-nameless backend, refer to \ahrefurl{http://moscova.inria.fr/~zappa/projects/ln\_ott/}. -\subsection{Generation of types} -\begin{itemize} -\item The primary metavariable roots and primary nonterminal roots are used - directly as the names of proof assistant types, except where they - have a hom specifying a root-overriding string. -\item Type abbreviation declarations are produced for metavars, in the - source-file order, skipping metavars or nonterminals defined with \mykw{phantom}. -\item Type generation considers each rule of the user's source grammar - except those for \verb+formula+ and \verb+terminals+ (or the - synthesized rules for the syntax of judgements or \verb+user_syntax+). -\item The subrule order is analysed to identify the top elements. For - each of those, a proof assistant type will be generated --- either a - free type (\verb+coq+: \verb+inductive+, \verb+isa+: - \verb+datatype+, \verb+hol+: \verb+Hol_datatype+), or if there is a - type hom for the proof assistant in question, a type abbreviation. - No types are generated for the non-top elements, as they will be - represented as predicates over the top free type above them. -\item For the former, each non-meta production of the rule - gives rise to a constructor. The production name (with any per-rule - prefix already applied) is used directly as the constructor name. - The (curried) constructor argument types are taken from the - types associated with the metavariables and nonterminals mentioned - in the production body. -\item Rules (within each \mykw{grammar} block, if \texttt{-merge -false}, or all rules, if \texttt{-merge true}) are topologically sorted according to the dependency order - (a free-type rule directly depends on another if one of its non-meta - productions includes a nonterminal of the other; dependencies for rules with a type-hom - for the proof assistant in question - are obtained from a crude lexing of the body of the type hom). - We then generate mutually recursive type - definitions for connected components, in an order consistent with - the dependencies. -\item For productions that involve list dot forms or list comprehension - forms, for HOL and Isabelle we produce constructors with argument - types that involve native list types. For Coq, however, we - synthesise an additional inductive type for each list-of-tuples that arises - (both for those that occur in the grammar and for others required in - the translations of inductive definitions) and include them in the - topological sort. -\end{itemize} - -\subsection{Generation of functions} -% -A small number of library functions (\verb+list_mem+, -\verb+list_minus+,...) are included in the output if they are -required. - -Several Coq list functions (\verb+map+, \verb+make+, \verb+unmake+, \verb+nth+, \verb+app+) are generated -for each synthesized list type. - -The definitions of the more interesting functions (subrule predicates, -binding auxiliaries, free variable functions, and substitutions) are -generated over the free types generated for the maximal elements of the -subrule order (generation of these functions for rules with type homs -is not supported). The definitions are by pattern-matching and -recursion. -The patterns are generated by building canonical symbolic terms from -the productions of each relevant rule. -The recursion is essentially primitive recursion: -for Coq we produce \verb+Fixpoint+s or \verb+Definition+s -(the latter is sometimes needed as the former gives an error in the case where there is no -recursion); -for Isabelle we produce \verb+primrec+s (or, experimentally, \verb+fun+s); -for HOL we use an \verb+ottDefine+ variant of the \verb+Define+ -package. -% -In general we have to deal both with the type dependency -(the topologically sorted mutually recursive types described above) -and with function dependency --- for example, for subrule predicates -and binding auxiliaries we may have multiple mutually recursive -functions over the same type. - - -For Coq the function generation over productions that involve list -types must mirror that, so we generate auxiliary functions -that recurse over those list types. - -For Isabelle the \verb+primrec+ package does not support -definitions involving several mutually recursive functions over the -same type, so for these we generate single functions calculating -tuples of results, define the intended functions as projections of -these, and generate lemmas (and simple proof scripts) characterising -them in terms of the intended definitions. -% -Further, it does not support pattern matching involving nested -constructors. We therefore generate auxiliary functions for -productions with embedded list types. Isabelle tuples are treated as -iterated pairs, so we do the same for productions with tuples of size -3 or more. -% -Isabelle also requires a function definition for each recursive type. -In the case where there are multiple uses of the same type -(e.g.~several uses of \verb+t list+ in different productions) all the -functions we wish to generate need identical auxiliaries. As yet, the -tool does not generate the identical copies required. - -If the option \verb+-isabelle_primrec+ is set to \verb+false+, then -Ott uses the \verb+fun+ package instead of the \verb+primrec+ package. -Since at the time of writing Isabelle 2008 is not capable of proving -automatically termination of all the \verb+fun+s that Ott generates, -this feature should be considered experimental. - -For HOL the standard \verb+Define+ package tries an automatic -termination proof. For productions that involve list types -our generated functions involve various list functions which prevent -those proofs working in all cases. -We therefore use an \verb+ottDefine+ variant (due to Scott Owens), - with slightly stronger support for proving termination of -definitions involving list operators. - - - -\subsubsection{Subrule predicates}\mlabel{a43}% -We generate subrule predicates to carve out the subsets of each free -proof assistant type (from the maximal elements of the subrule order) -that represent the rules of the grammar. -The non-free rules are the least subset of the rules that either -(1) occur on the left of a subrule (\verb+<::+) declaration, or -(2) have a (non-meta) production that mentions a non-free rule. -Note that these can include rules that are maximal elements of the -subrule order, e.g.~if an expression grammar included a production -involving packaged values. -The subrule predicate for a type is defined by pattern matching over -constructors of the maximal type above it --- for each non-meta -production of the maximal type it calculates a disjunction -over all the productions of the lower type that are subproductions of -it, invoking other subrule predicates as appropriate. - - -\subsubsection{Binding auxiliaries} -The binding auxiliary functions calculate the intuitive semantics of auxiliary functions defined in bindspecs of the Ott source file. Currently these are represented as proof assistant lists of metavariables or nonterminals (arguably set types should be used instead, at least in Isabelle). - - -\subsubsection{Free variables} -The free variable functions simply walk over the structure of the free proof assistant types, using any bind specifications (and binding auxiliaries) as appropriate. -% -For these, and for substitutions, we simplify the generated functions by using the dependency analysis of the syntax to exclude recursive calls where there is no dependency. - - -\subsubsection{Substitutions} -The generated substitution functions also walk over the structure of the free proof assistant types. -For each production, for each occurrence of a nonterminal \verb+nt+ within it, we first calculate the things (of whatever type is in question) binding in that \verb+nt+, i.e.~those that should be removed from the domain of any substitution pushed down into it. There are two cases: -(1) the \verb+mse'+ from any \verb+bind mse' in nt+; -%(2) the \verb+f(nt)+ which occur in the \verb+mse''+ of any \verb+bind mse'' in nt''+ -% in the production, i.e.~any auxiliary-defined things within \verb+nt+ which are used to bind elsewhere; and -(2) \verb+nt+ itself if it occurs in the \verb+mse''+ of any \verb+bind mse'' in nt''+, i.e.~ -\verb+nt+ itself if it is directly used to bind elsewhere. -List forms within bindspecs are dealt with analogously. -% - -The substitution function clause for a production is then of one of two forms: -either (1) the production comprises a single element, of the nonterminal or metavariable that we are substituting for, and this is within the rule of the nonterminal that it is being replaced by, or (2) all other cases. -For (1) the element is compared with the domain of the substitution, and replaced by the corresponding value from the range if it is found. -For (2) the substitution functions are mapped over the subelements, having first removed any bound things from the domain of the substitution. - -This is all done similarly, but with differences in detail, for single and for multiple substitutions. - - -\subsection{Generation of relations} -The semantic relations are defined -with the proof-assistant inductive relations packages -(\verb+coq+: \verb+Inductive+, -\verb+isa+: \verb+inductive+, -\verb+hol+: \verb+Hol_reln+). -% -They use the mutual recursion structure that is given by the user, -with each \verb+defns+ block giving rise to a potentially mutually -recursive definition of each \verb+defn+ inside it. -(It is debatable whether it would be preferable to do an automatic dependency analysis and topological sort, as for the syntax.) -% -Each definition rule gives rise to an implicational clause, essentially -that the premises (Ott \verb+formula+s) imply the conclusion (an Ott symbolic term of whichever judgement is being defined). -In addition: -\begin{itemize} -\item Symbolic terms are transformed in various different ways: -\begin{itemize} -\item Nodes of non-meta productions are output as applications of the appropriate proof-assistant constructor (and, for a subrule, promoted to the corresponding constructor of a maximal rule). -\item Nodes of meta productions are transformed with the user-specified homomorphism. -\item Nodes of judgement forms are represented as applications of the defined relation in Coq and HOL, and as set-membership assertions in Isabelle. -\item Lists of formulae (the \verb+formula_dots+ production) are special-cased. -\end{itemize} -\item For each nonterminal of a non-free syntax rule (as in \S\mref{a43}) that occurs, - e.g.~a usage of \verb+v'+ where \verb+v<::t+, an additional premise invoking the subrule predicate for the non-free rule is added, e.g.~\verb+is_v v'+. -\item The set of symbolic terms of the definition rule are analysed together to identify list forms with the same bounds. A single proof assistant variable is introduced for each such, with appropriate projections and list maps/foralls at the usage points. -\item For Coq, auxiliary defined relations are introduced for list forms. -\item For Coq, as the projections from list forms involve (Ott-generated) \verb+nth+ functions that return option types, for any such projection a pattern-match against \verb+Some+ is introduced as an additional premise. -\item For Coq and HOL, explicit quantifiers are introduced for all variables mentioned in the rule. -\end{itemize} - - - - -\section{Reference: Summary of homomorphisms}\mlabel{a41}% -% -Homomorphisms can appear in various positions in an Ott source -file.

The OCaml manual~\cite{ocaml2005} -defines the syntax with a BNF; our syntax is based on that. -It describes the semantics in prose; our semantics is based on a -combination of that and our experience with the language. - -\myaspect{Experience} -Our experience with these examples has been very positive. The tool, -while not perfect, does make it easy to work with these -definitions, allowing one to focus on the content rather than the -proof assistant or \myLaTeX{} markup. - -For our most substantial example, the OCaml fragment, to date we have proved type preservation and -progress for the expression language, all machine-checked in HOL -except for one currently outstanding lemma (type substitution for type -variables) for -which we have a paper proof. -Alpha equivalence arises only in a lemma showing that typing is preserved by renaming the bound variables of a type scheme in the type environment. -This proof effort has -taken only around 7 man-weeks, and the preceeding definition effort -was only another few man-weeks. -Compared with our previous experiences this is remarkably lightweight: it -has been possible to develop this as an example, rather than requiring -a major research project in its own right. -Apart from \texttt{ott}, the work has been aided by HOL's powerful first-order -reasoning automation and its inductive definition package, and by the -use of the fully concrete representation. - - -We have attempted to ensure that the proof assistant definitions -generated by Ott are well-formed and what the user would intend. This -is not guaranteed, however, for several reasons: (1) There may be name -clashes between Ott-generated identifiers and proof assistant built-in -identifiers (or, in pathological cases, even among different -Ott-generated identifiers). (2) In some cases we depend on automatic -proof procedures, e.g.~for HOL definitions. These work in our test -cases, but it is hard to ensure that they will in all cases. More -importantly, (3) the generation process is complex, so it is quite -possible that there is either a bug in Ott or a mismatch between the -user expectation and what the tool actually does. Ultimately one has -to read the generated proof assistant definitions to check that they -are as intended --- but typically one would do this in any case, many -times over, in the process of proving metatheoretic results, so we do -not consider it a major issue. - - -\begin{figure} -\fbox{\begin{minipage}{\textwidth} -\input{test10.0.alltt} -\end{minipage}} -\caption{Source: \texttt{test10.0.ott}\protect\label{a4}} -\end{figure} - -\begin{figure} -\fbox{\begin{minipage}{\textwidth} -\input{test10.2.alltt} -\end{minipage}} -\caption{Source: \texttt{test10.2.ott}\protect\label{a4}} -\end{figure} - -\begin{figure} -\fbox{\begin{minipage}{\textwidth} -\input{test10.4.alltt} -\end{minipage}} -\caption{Source: \texttt{test10.4.ott}\protect\label{a4}} -\end{figure} - -\begin{figure} -\fbox{\begin{minipage}{\textwidth} -\input{test10.7.alltt} -\end{minipage}} -\caption{Source: \texttt{test10.7.ott}\protect\label{a4}} -\end{figure} - - - -\begin{figure} -\fbox{\begin{minipage}{\textwidth} -\verbatiminput{../tests/test10.ott} -\end{minipage}} -\caption{Source: \texttt{test10.ott}\protect\label{a4}} -\end{figure} - -\begin{figure} -\fbox{\begin{minipage}{\textwidth} -\testTenall -\end{minipage}} -\caption{Generated \myLaTeX: \texttt{test10.tex}\protect\label{a3}} -\end{figure} - - -\section{Example: Untyped CBV Lambda Calculus}\mlabel{a2}% -We begin with a small example, an untyped call-by-value lambda -calculus. Below we highlight the main points shown in this example ---- which uses many, but not all, of the features of Ott. We return -to the options in more detail in later sections. - -The complete Ott source file is shown in Fig.~\mref{a4}, the typeset -output in Fig.~\mref{a3}, and the generated Isabelle, Coq, and HOL files -in Figs.~\mref{a5}, \mref{a6}, and \mref{a40}. -% (the latter have been -%lightly hand-edited to remove redundant definitions so that they each fit -%on a page). - -Looking at the source file in Fig.~\mref{a4}, it begins by declaring a -metavariable form \texttt{x}, giving the Isabelle, Coq, and HOL types used -(\texttt{string}, \texttt{nat}, and \texttt{string} respectively) to represent concrete -variables, and also specifying how metavariables should be typeset. - -The following \texttt{grammar} block contains 4 grammar rules, defining -the (concrete and abstract) syntax for nonterminal roots \texttt{t}, -\texttt{v}, \texttt{terminals}. -% -Each rule has a rule name prefix (e.g.~\texttt{t\_}) and then a list -of productions. Each production, e.g. -\begin{verbatim} - \mysym{|} \ x . t :: :: Lam (+ bind x in t +) {{ com abstraction }} -\end{verbatim} -specifies a syntactic form as a list of elements, here `\verb+\+', -`\verb+x+', `\verb+.+', and `\verb+t+', each of which is either a -metavariable (the `\verb+x+'), a nonterminal (the `\verb+t+'), or a -terminal (the `\verb+\+' and `\verb+.+'). -Within productions all elements must be whitespace-separated (so that -the tool can deduce which are terminals). In the symbolic terms in -the rules below, however, whitespace is required only where necessary. - - -Metavariables and nonterminals can be formed from the specified -metavariable and nonterminal roots by appending a suffix, e.g.~the -nonterminal \verb+t'+ in the \verb+App+ and \verb+tsub+ productions. - -Terminals are not required to be declared in the \texttt{terminals} -grammar (all strings that are not metavariables or nonterminals are -regarded as terminals) but, if they are, then \myLaTeX{} pretty printing -information for them can be specified there. In this example the -`\verb+\+' is included in the \texttt{terminals} grammar and will be -\myLaTeX pretty printed as a $\lambda$, whereas the `\verb+.+' is not -included and will be pretty printed in a default form. -A few terminals have to be quoted in the grammar, as they are part of the Ott syntax, but they -do not have to be quoted at usage points. - - - -Between the \verb+::+s is an optional meta flag \verb+M+. Non-meta -productions give rise to clauses of datatype definitions in the -Isabelle/Coq/HOL output, whereas meta productions do not. - -Each production has a production name (e.g.~\verb+t_Lam+), composed of -the rule name prefix (e.g.~\verb+t_+) and the production name kernel -that follows the \verb+::+s (e.g.~\verb+Lam+). The production name is -used as a constructor name in the generated Isabelle/Coq/HOL. - -Following the production name is an optional binding specification -(e.g.~\verb-(+ bind x in t +)-), specifying which metavariables (or -nonterminals) bind in which nonterminals. This is used in the -generation of substitution and free variable functions. - -At present the generated Isabelle/Coq/HOL uses completely concrete -representations of variables in terms, without any notion of alpha -equivalence, as one can see in Fig.~\mref{a5}: -see the \verb+t+ datatype of terms and the \verb+tsubst_t+ -substitution function there. -We intend in future to generate other representations. -For a reasonably wide variety of -languages, however, one can capture the intended semantics of whole programs in -this idiom, subject only to the condition that standard library -identifiers are not shadowed within the program, as the operational -semantics does not involve reduction under binders --- so any -substitutions are of terms which (except for standard library -identifiers) are closed. This includes the ML polymorphism example of -\verb+test8.ott+.%\S\mref{a23}. -Unfortunately, for languages which require a type -environment with internal dependencies, for example F$_{<:}$, this is -no longer the case, and the POPLmark F$_{<:}$ example given in -\verb+test7.ott+ %\S\mref{a26} -has a type system which disallows all shadowing, a property that is -not preserved by reduction. - - - -Finally, there may be a number of homs, defining clauses of -homomorphisms from the grammar to strings. Certain homs have special -meanings, including: - -\begin{tabular}{ll} -\verb+com+ & defining comments used in \myLaTeX{} pretty prints of the grammar\\ -\verb+tex+ & defining how this production (and terms formed by it) are \myLaTeX{} pretty printed\\ -\verb+isa+ & (for meta productions) defining how the terms formed by -the production are translated into Isabelle\\ -\verb+coq+ & similarly for Coq\\ -\verb+hol+ & similarly for HOL\\ -\verb+ich+ & a shorthand for defining an identical triple of \verb+isa+, - \verb+coq+, and \verb+hol+ homs -\end{tabular} - -Section \mref{a41} gives a summary of all the usable homomorphisms. - -Following the \texttt{grammar} in this example is a \texttt{subrule} -declaration -\begin{verbatim} - subrules - v <:: t -\end{verbatim} -declaring that the \verb+v+ rule (of values) is a -subgrammar of the \verb+t+ rule (of terms). The tool checks that -there is in fact a subgrammar relationship, i.e.~that for each -production of the lower rule there exists a production of the higher -rule with corresponding elements (up to the subrule relation). -In the generated Isabelle/Coq/HOL for this example only one free -datatype is generated, for the \verb+t+ rule, whereas for the \verb+v+ -rule we generate an \verb+is_v+ predicate over the \verb+t+ type. Usages of -\verb+v+ nonterminals in the semantic rules have instances of this -predicate automatically inserted. - -We continue with a substitutions declaration -\begin{verbatim} - substitutions - single t x :: tsubst -\end{verbatim} -instructing the tool to generate Isabelle/Coq/HOL for a substitution -function replacing metavariables by terms. This is for single -substitutions; multiple substitution functions (taking lists of -substitutand/substitutee pairs) can also be generated. -Substitution functions are generated for all rules of the grammar for -which they might be required --- here, just over \verb+t+, with a -function named \verb+tsubst_t+. Such functions can be used in the -\verb+isa+/\verb+coq+/\verb+hol+ homomorphisms for meta syntax, e.g. as in the -production -\begin{verbatim} - | { t / x } t' :: M :: tsub {{ ich ( tsubst_t [[t]] [[x]] [[t']] ) }} -\end{verbatim} -introducing syntax for term substitution. - - -Finally, we give a collection of definitions of inductive relations. -In this example there is just one family of definitions (of -operational judgements), called \verb+Jop+; it contains just one -definition of a relation, called \verb+E+. The relation definition -also includes a grammar production specifying how elements of the -relation can be written and typeset, here -\begin{verbatim} - t1 --> t2 -\end{verbatim} -Syntax rules for each family of -judgements, and for their union, are implicitly generated. -The relation definition is given by a sequence of inference rules, -each with a horizontal line separating a number of premises from a -conclusion, for example as below. -\begin{verbatim} - t1 --> t1' - -------------- :: ctx_app_arg - v t1 --> v t1' -\end{verbatim} -The conclusion must be a symbolic term of the form of the judgement being -defined. -In simple cases (as here) the premises can be symbolic terms of the -form of any of the defined judgements. More generally (see -\S\mref{a13}) they can be symbolic terms of a user-defined -\texttt{formula} grammar. -Each rule - has a name, composed of a definition family prefix -(here empty), a definition prefix (here also empty) and a kernel -(the~\verb+ctx_app_arg+). - - - - - - - - - -\begin{figure} -\fbox{\begin{minipage}{\textwidth} -\verbatiminput{test10.thy} -%\verbatiminput{test10.hand.edited.thy} -\end{minipage}} -\caption{Generated Isabelle:\texttt{test10.thy}\protect\label{a5}} -\end{figure} - -\begin{figure} -\fbox{\begin{minipage}{\textwidth} -\verbatiminput{test10.v} -%\verbatiminput{test10.hand.edited.v} -\end{minipage}} -\caption{Generated Coq:\texttt{test10.v}\protect\label{a6}} -\end{figure} - -\begin{figure} -\fbox{\begin{minipage}{\textwidth} -\verbatiminput{test10Script.sml} -\end{minipage}} -\caption{Generated HOL:\texttt{test10Script.sml}\protect\label{a40}} -\end{figure} - - -% \section{\texttt{test1}} -% \testOneall -% -% \section{\texttt{test8}} -% \testEightall - -\clearpage - -\section{Command-line Usage}\mlabel{a32}% -The best place to get started is probably one of the test -\texttt{make} targets in the \texttt{ott} directory, e.g. -\begin{verbatim} -test10: tests/test10.ott - bin/ott \ - -isabelle out.thy -coq out.v -hol outScript.sml \ - -tex out.tex \ - -parse ":t: (\z.z z) y" \ - tests/test10.ott \ - && ($(LATEX) out; $(DVIPS) out -o) -\end{verbatim} -When \verb+make test10+ is executed, \texttt{ott}: -\begin{itemize} -\item reads the source file \verb+tests/test10.ott+ -\item prints on standard output various diagnostic information, - including ASCII versions of the grammar and - inductive definitions. - By default these are coloured (using - \verb+vt220+ control codes) with metavariables in red, nonterminals - in yellow, terminals in green, and object variables in white. - Scanning over this output quickly picks up some common errors. -\item parses the symbolic term \verb+(\z.z z) y+ using the \verb+t+ - grammar and prints the result to standard output -\item generates Isabelle definitions in the file \verb+out.thy+ -\item generates Coq definitions in the file \verb+out.v+ -\item generates HOL definitions in the file \verb+outScript.sml+ -\item generates a \myLaTeX{} document in the file \verb+out.tex+, with a - standard document preamble to make it self-contained. -\end{itemize} -That \myLaTeX{} document is then compiled and converted to postscript. - -If multiple source files are specified then they are (after parsing) -concatenated together. - - -The~\verb+%.out+ \verb+Makefile+ target runs \verb+ott+ with common -defaults on the file~\verb+%.ott+, so for example executing \verb+make tests/test10.out+ -runs \verb+ott+ on \verb+tests/test10.ott+, generating all outputs.

It is written in Ott~\cite{ott}, which generates -\LaTeX, HOL, Coq, and Isabelle/HOL definitions, and it comprises a small-step -operational semantics and a syntactic, non-algorithmic type system. A type -soundness theorem has been proved and mechanized in HOL-4. To ensure that the -operational semantics accurately models Objective Caml, an executable version -of the semantics has been created (and proved equivalent in HOL to the -original, relational version) and tested on a number of small test cases. - -We take a straightforward approach, formalizing the syntax of \OCL{} as a -collection of inductive datatypes, and the \OCL{} type system and operational -semantics as a collection of inductive relations and recursive functions -directly over the source syntax. We hypothesize that this clear connection -between the source language and its semantics will facilitate verification -about \OCL{} programs, in addition to the present verification of type -soundness. \OCL{} covers a large part of Objective Caml, but excludes the -language's module and object systems. It includes: -\begin{itemize} -\item -definitions -\begin{itemize} -\item -variant data types (e.g., \verb+type t = I of int | C of char+), -\item -record types (e.g., \verb+type t = {f : int; g : bool}+), -\item -parametric type constructors (e.g., \verb+type 'a t = C of 'a+), -\item -type abbreviations (e.g., \verb+type 'a t = 'a * int+), -\item -mutually recursive combinations of the above (excepting abbreviations), -\item -exceptions, and values; -\end{itemize} -\item -expressions for type annotations, sequencing, and primitive values (functions, lists, tuples, and records); -\item -\verb+with+ (record update), \verb+if+, \verb+while+, \verb+for+, \verb+assert+, \verb+try+, and \verb+raise+ expressions; -\item -let-based polymorphism with an SML-style value restriction; -\item -mutually-recursive function definitions via \verb+let rec+; -\item -pattern matching, with nested patterns, \verb+as+ patterns, and ``or'' (\verb+|+)patterns; -\item -mutable references with \verb+ref+, \verb+!+, and \verb+:=+; -\item -polymorphic equality (the Objective Caml \verb+=+ operator); -\item -31-bit word semantics for \texttt{int}s (using an existing HOL library); and -\item -IEEE-754 semantics for \texttt{float}s (using an existing HOL library). -\end{itemize} - -Most of the proof effort is a straightforward application of HOL's tactic-based proof mechanisms.

The pretty-printer breaks lines at specified break -%hints, and indents lines according to the box structure. -% For a gentle introduction to the basics of pretty-printing using Format, -%read -%http://caml.inria.fr/resources/doc/guides/format.html[http://caml.inria.fr/reso -%urces/doc/guides/format.html]. -% Warning: the material output by the following functions is delayed in the -%pretty-printer queue in order to compute the proper line breaking. Hence, you -%should not mix calls to the printing functions of the basic I/O system with -%calls to the functions of this module: this could result in some strange -%output seemingly unrelated with the evaluation order of printing commands. -% You may consider this module as providing an extension to the printf -%facility to provide automatic line breaking. The addition of pretty-printing -%annotations to your regular printf formats gives you fancy indentation and -%line breaks. Pretty-printing annotations are described below in the -%documentation of the function Format.fprintf[20.9]. -% You may also use the explicit box management and printing functions provided -%by this module. This style is more basic but more verbose than the fprintf -%concise formats. -% For instance, the sequence open_box 0; print_string "x ="; print_space (); -%print_int 1; close_box () that prints x = 1 within a pretty-printing box, can -%be abbreviated as printf "@[%s@ %i@]" "x =" 1, or even shorter printf "@[x =@ -%%i@]" 1. -% Rule of thumb for casual users of this library: -% -% - use simple boxes (as obtained by open_box 0); -% - use simple break hints (as obtained by print_cut () that outputs a simple -% break hint, or by print_space () that outputs a space indicating a break -% hint); -% - once a box is opened, display its material with basic printing functions -% (e. g. print_int and print_string); -% - when the material for a box has been printed, call close_box () to close -% the box; -% - at the end of your routine, evaluate print_newline () to close all -% remaining boxes and flush the pretty-printer. -% -% The behaviour of pretty-printing commands is unspecified if there is no -%opened pretty-printing box. Each box opened via one of the open_ functions -%below must be closed using close_box for proper formatting. Otherwise, some of -%the material printed in the boxes may not be output, or may be formatted -%incorrectly. -% In case of interactive use, the system closes all opened boxes and flushes -%all pending text (as with the print_newline function) after each phrase. Each -%phrase is therefore executed in the initial state of the pretty-printer. -% 0.5cm -% -%Boxes -%===== -% -%<< -% val open_box : int -> unit -%>> -% -% open_box d opens a new pretty-printing box with offset d. -% This box is the general purpose pretty-printing box. Material -% in this box is displayed --horizontal or vertical--: break -% hints inside the box may lead to a new line, if there is no -% more room on the line to print the remainder of the box, or if -% a new line may lead to a new indentation (demonstrating the -% indentation of the box). When a new line is printed in the box, -% d is added to the current indentation. -% -%<< -% val close_box : unit -> unit -%>> -% -% Closes the most recently opened pretty-printing box. -% -% -%Formatting functions -%==================== -% -%<< -% val print_string : string -> unit -%>> -% -% print_string str prints str in the current box. -% -%<< -% val print_as : int -> string -> unit -%>> -% -% print_as len str prints str in the current box. The -% pretty-printer formats str as if it were of length len. -% -%<< -% val print_int : int -> unit -%>> -% -% Prints an integer in the current box. -% -%<< -% val print_float : float -> unit -%>> -% -% Prints a floating point number in the current box. -% -%<< -% val print_char : char -> unit -%>> -% -% Prints a character in the current box. -% -%<< -% val print_bool : bool -> unit -%>> -% -% Prints a boolean in the current box. -% -% -%Break hints -%=========== -% -%<< -% val print_space : unit -> unit -%>> -% -% print_space () is used to separate items (typically to print a -% space between two words).

It is equivalent to print_break 1 0. -% -%<< -% val print_cut : unit -> unit -%>> -% -% print_cut () is used to mark a good break position. It -% indicates that the line may be split at this point. It either -% prints nothing or splits the line. This allows line splitting -% at the current point, without printing spaces or adding -% indentation. It is equivalent to print_break 0 0. -% -%<< -% val print_break : int -> int -> unit -%>> -% -% Inserts a break hint in a pretty-printing box. print_break -% nspaces offset indicates that the line may be split (a newline -% character is printed) at this point, if the contents of the -% current box does not fit on the current line. If the line is -% split at that point, offset is added to the current -% indentation. If the line is not split, nspaces spaces are -% printed. -% -%<< -% val print_flush : unit -> unit -%>> -% -% Flushes the pretty printer: all opened boxes are closed, and -% all pending text is displayed. -% -%<< -% val print_newline : unit -> unit -%>> -% -% Equivalent to print_flush followed by a new line. -% -%<< -% val force_newline : unit -> unit -%>> -% -% Forces a newline in the current box.

Otherwise, ignore the next formatting command. -% -% -%Margin -%====== -% -%<< -% val set_margin : int -> unit -%>> -% -% set_margin d sets the value of the right margin to d (in -% characters): this value is used to detect line overflows that -% leads to split lines.

Nothing occurs if insertion point is -% already on a tabulation mark. If there is no next tabulation -% on the line, then a newline is printed and the insertion point -% moves to the first tabulation of the box. If a new line is -% printed, offset is added to the current indentation. -% -%<< -% val set_tab : unit -> unit -%>> -% -% Sets a tabulation mark at the current insertion point. -% -%<< -% val print_tab : unit -> unit -%>> -% -% print_tab () is equivalent to print_tbreak (0,0). -% -% -%Ellipsis -%======== -% -%<< -% val set_ellipsis_text : string -> unit -%>> -% -% Set the text of the ellipsis printed when too many boxes are -% opened (a single dot, ., by default). -% -%<< -% val get_ellipsis_text : unit -> string -%>> -% -% Return the text of the ellipsis. -% -% -%Tags -%==== -% -%<< -% type tag = string -%>> -% -% Tags are used to decorate printed entities for user-s defined purposes, e.g. -%setting font and giving size indications for a display device, or marking -%delimitations of semantics entities (e.g. HTML or TeX elements or terminal -%escape sequences). -% By default, those tags do not influence line breaking calculation: the tag -%--markers-- are not considered as part of the printing material that drives -%line breaking (in other words, the length of those strings is considered as -%zero for line breaking). -% Thus, tag handling is in some sense transparent to pretty-printing and does -%not interfere with usual pretty-printing. Hence, a single pretty printing -%routine can output both simple --verbatim-- material or richer decorated -%output depending on the treatment of tags. By default, tags are not active, -%hence the output is not decorated with tag information. Once set_tags is set -%to true, the pretty printer engine honors tags and decorates the output -%accordingly. -% When a tag has been opened (or closed), it is both and successively -%--printed-- and --marked--. Printing a tag means calling a formatter specific -%function with the name of the tag as argument: that --tag printing-- function -%can then print any regular material to the formatter (so that this material is -%enqueued as usual in the formatter queue for further line'breaking -%computation). Marking a tag means to output an arbitrary string (the --tag -%marker--), directly into the output device of the formatter. Hence, the -%formatter specific --tag marking-- function must return the tag marker string -%associated to its tag argument. Being flushed directly into the output device -%of the formatter, tag marker strings are not considered as part of the -%printing material that drives line breaking (in other words, the length of the -%strings corresponding to tag markers is considered as zero for line -%breaking). In addition, advanced users may take advantage of the specificity -%of tag markers to be precisely output when the pretty printer has already -%decided where to break the lines, and precisely when the queue is flushed into -%the output device. -% In the spirit of HTML tags, the default tag marking functions output tags -%enclosed in "<" and ">": hence, the opening marker of tag t is "" and the -%closing marker "". -% Default tag printing functions just do nothing. -% Tag marking and tag printing functions are user definable and can be set by -%calling set_formatter_tag_functions. -%<< -% val open_tag : tag -> unit -%>> -% -% open_tag t opens the tag named t; the print_open_tag function -% of the formatter is called with t as argument; the tag marker -% mark_open_tag t will be flushed into the output device of the -% formatter. -% -%<< -% val close_tag : unit -> unit -%>> -% -% close_tag () closes the most recently opened tag t. In -% addition, the print_close_tag function of the formatter is -% called with t as argument. The marker mark_close_tag t will be -% flushed into the output device of the formatter. -% -%<< -% val set_tags : bool -> unit -%>> -% -% set_tags b turns on or off the treatment of tags (default is -% off). -% -%<< -% val set_print_tags : bool -> unit -%>> -% -%<< -% val set_mark_tags : bool -> unit -%>> -% -% set_print_tags b turns on or off the printing of tags, while -% set_mark_tags b turns on or off the output of tag markers. -% -%<< -% val get_print_tags : unit -> bool -%>> -% -%<< -% val get_mark_tags : unit -> bool -%>> -% -% Return the current status of tags printing and tags marking. -% -% -%Redirecting formatter output -%============================ -% -%<< -% val set_formatter_out_channel : Pervasives.out_channel -> unit -%>> -% -% Redirect the pretty-printer output to the given channel. -% -%<< -% val set_formatter_output_functions : -% (string -> int -> int -> unit) -> (unit -> unit) -> unit -%>> -% -% set_formatter_output_functions out flush redirects the -% pretty-printer output to the functions out and flush. -% The out function performs the pretty-printer output.

The first argument must therefore have type -% out_channel -> 'b -> unit and the second 'b. The output -% produced by the function is therefore inserted in the output -% of fprintf at the current point. -% - t: same as %a, but takes only one argument (with type -% out_channel -> unit) and apply it to outchan. -% - !: take no argument and flush the output. -% - %: take no argument and output one % character. -% -% The optional flags include: -% -% - -: left-justify the output (default is right justification). -% - 0: for numerical conversions, pad with zeroes instead of -% spaces. -% - +: for numerical conversions, prefix number with a + sign if -% positive. -% - space: for numerical conversions, prefix number with a space -% if positive. -% - `#': request an alternate formatting style for numbers. -% -% The field widths are composed of an optional integer literal -% indicating the minimal width of the result, possibly followed by -% a dot . and another integer literal indicating how many digits -% follow the decimal point in the %f, %e, and %E conversions. For -% instance, %6d prints an integer, prefixing it with spaces to -% fill at least 6 characters; and %.4f prints a float with 4 -% fractional digits.

Hence, a -% space in the format matches any amount of whitespace in the -% input. -% Conversion specifications consist in the % character, followed -% by an optional flag, an optional field width, and followed by -% one or two conversion characters. The conversion characters and -% their meanings are: -% -% -% - d: reads an optionally signed decimal integer. -% - i: reads an optionally signed integer (usual input formats -% for hexadecimal (0x[d]+ and 0X[d]+), octal (0o[d]+), and -% binary 0b[d]+ notations are understood). -% - u: reads an unsigned decimal integer. -% - x or X: reads an unsigned hexadecimal integer. -% - o: reads an unsigned octal integer. -% - s: reads a string argument (by default strings end with a -% space). -% - S: reads a delimited string argument (delimiters and special -% escaped characters follow the lexical conventions of Caml). -% - c: reads a single character. To test the current input -% character without reading it, specify a null field width, -% i.e. use specification %0c. Raise Invalid_argument, if the -% field width specification is greater than 1. -% - C: reads a single delimited character (delimiters and special -% escaped characters follow the lexical conventions of Caml). -% - f, e, E, g, G: reads an optionally signed floating-point -% number in decimal notation, in the style dddd.ddd e/E+-dd. -% - F: reads a floating point number according to the lexical -% conventions of Caml (hence the decimal point is mandatory if -% the exponent part is not mentioned). -% - B: reads a boolean argument (true or false). -% - b: reads a boolean argument (for backward compatibility; do -% not use in new programs). -% - ld, li, lu, lx, lX, lo: reads an int32 argument to the -% format specified by the second letter (decimal, hexadecimal, -% etc). -% - nd, ni, nu, nx, nX, no: reads a nativeint argument to the -% format specified by the second letter. -% - Ld, Li, Lu, Lx, LX, Lo: reads an int64 argument to the -% format specified by the second letter. -% - [ range ]: reads characters that matches one of the -% characters mentioned in the range of characters range (or -% not mentioned in it, if the range starts with ^). Returns a -% string that can be empty, if no character in the input -% matches the range. Hence, [0-9] returns a string -% representing a decimal number or an empty string if no -% decimal digit is found. If a closing bracket appears in a -% range, it must occur as the first character of the range (or -% just after the ^ in case of range negation); hence []] -% matches a ] character and [^]] matches any character that is -% not ]. -% - l: applies f to the number of lines read so far. -% - n: applies f to the number of characters read so far. -% - N: applies f to the number of tokens read so far. -% - !: matches the end of input condition. -% - %: matches one % character in the input. -% -% Following the % character introducing a conversion, there may be -% the special flag _: the conversion that follows occurs as -% usual, but the resulting value is discarded. -% The field widths are composed of an optional integer literal -% indicating the maximal width of the token to read. For -% instance, %6d reads an integer, having at most 6 decimal digits; -% and %4f reads a float with at most 4 characters. -% Scanning indications appear just after the string conversions s -% and [ range ] to delimit the end of the token. A scanning -% indication is introduced by a @ character, followed by some -% constant character c. It means that the string token should end -% just before the next matching c (which is skipped). If no c -% character is encountered, the string token spreads as much as -% possible. For instance, "%s@\t" reads a string up to the next -% tabulation character. If a scanning indication @c does not -% follow a string conversion, it is ignored and treated as a plain -% c character. -% Notes: -% -% -% - the scanning indications introduce slight differences in the -% syntax of Scanf format strings compared to those used by the -% Printf module. However, scanning indications are similar to -% those of the Format module; hence, when producing formatted -% text to be scanned by !Scanf.bscanf, it is wise to use -% printing functions from Format (or, if you need to use -% functions from Printf, banish or carefully double check the -% format strings that contain -@- characters). -% -% -% - in addition to relevant digits, -_- characters may appear -% inside numbers (this is reminiscent to the usual Caml -% conventions). If stricter scanning is desired, use the range -% conversion facility instead of the number conversions. -% -% -% - the scanf facility is not intended for heavy duty lexical -% analysis and parsing. If it appears not expressive enough for -% your needs, several alternative exists: regular expressions -% (module Str), stream parsers, ocamllex-generated lexers, -% ocamlyacc-generated parsers. -% -%<< -% val fscanf : -% Pervasives.in_channel -> -% ('a, Scanning.scanbuf, 'b) Pervasives.format -> 'a -> 'b -%>> -% -% Same as Scanf.bscanf[20.27], but inputs from the given channel. -% Warning: since all scanning functions operate from a scanning -% buffer, be aware that each fscanf invocation must allocate a new -% fresh scanning buffer (unless careful use of partial evaluation -% in the program).

It -%will not take advantage of multi-processor machines. Using this library will -%therefore never make programs run faster. However, many programs are easier to -%write when structured as several communicating processes. -% Two implementations of the threads library are available, depending on the -%capabilities of the operating system: -% -% - System threads.

The main differences between -'big -%arrays-- and standard Caml arrays are as follows: -% -% - Big arrays are not limited in size, unlike Caml arrays (float array are -% limited to 2097151 elements on a 32'bit platform, other array types to -% 4194303 elements). -% - Big arrays are multi-dimensional. Any number of dimensions between 1 and 16 -% is supported. In contrast, Caml arrays are mono-dimensional and require -% encoding multi-dimensional arrays as arrays of arrays. -% - Big arrays can only contain integers and floating-point numbers, while Caml -% arrays can contain arbitrary Caml data types.

Terminology

+ +
+
Instruction
+
Instructions refers to Michelson primitives such as ADD. + Not to be confused with operations.
+
Operation
+
The side effect of a contract execution is a new storage and a list of operations. + An operation is either a transfer, an account creation or a delegation.
+
Numerical type
+
Refers to any of the numerical types of Michelson: + int, + nat, + timestamp or + mutez. + Numerical values are values of one these types. +
Sequence type
+
Refers to any of the two sequence type of Michelson: string or bytes. +
+
Structural type
+
Refers to any of the structural types of Michelson: + list, + set, + map or + big_map. + Structural values are values of one these types. +
+
Argument
+
Michelson instructions may be indexed by arguments. + For instance, the + arguments of PUSH nat 3 is nat and 3. + The argument of DIP 2 is 2. + Not to be confused with operands and parameters. +
+
Operand
+
Refers to stack values consumed by instructions. + Not to be confused with arguments and parameters. +
+
Parameter
+
Parameter may refer to three things. + First, each contract has a parameter type and when called, takes a parameter value of this type. + Second, some michelson data types, such as list are parametric. + For instance, a list of integer list nat is an instance of the list type with + the type parameter instantiated to nat. + Finally, the input type of a lambda. + Not to be confused with arguments and operands. +
+
Return value
+
Refers either to the stack values produced by an instruction, or the return value of a lambda. +
+
+
