2001-03-28 Shiro Kawai <shiro@scherzo>
* release 0.2.14
* src/class.c: added generic function write-object.
* src/error.c, src/vm.c, src/gauche/vm.h: added vm->errorFlags,
and use SCM_ERROR_BEING_HANDLED flag to avoid inifinite loop
of calling error function.
2001-03-27 Shiro Kawai <shiro@scherzo>
* release 0.2.13
* src/vm.c, src/compile.c: finally deals with let-family, do and
receive properly tail recursive way.
consolidate compiler flags.
* src/main.c: added -fno-source-info option. it disables inserting
debug information into the final code, and improves performance
considerably.
* lib/gauche/vm/disasm.scm: more reasonable output format.
* lib/gauche/object.scm: added class-slot-ref and class-slot-set!
2001-03-26 Shiro Kawai <shiro@scherzo>
* release 0.2.12
* lib/gauche/object.scm (compute-get-n-set): implemented class,
each-subclass and virtual slot allocation.
* src/class.c: if a slot accessor returns UNDEFINED, regard it
as an unbound slot and call slot-missing. Necessary for virtual
slots to tell the system that slot is unbound.
* src/class.c (method_more_specific): fixed a bug.
* src/class.c (Scm_AddMethod): check for method redefinition of
the same signature.
* src/extlib.stub: added undefined and undefined? to treat undefined
value explicitly in Scheme.
* src/vm.c: fixed a bug with inlined slot-ref and slot-set!, that
broke VM stack when Scm_VMApply was called internally.
2001-03-25 Shiro Kawai <shiro@scherzo>
* release 0.2.11
* lib/gauche/object.scm: support :getter, :setter and :accessor
slot options.

VM regs before calling Scm_Error.
2001-03-24 Shiro Kawai <shiro@scherzo>
* release 0.2.10
* test/object.scm: test file for object system.

code to deal with Scheme-defined slots.
* src/class.c (Scm_MakeBaseGeneric): added for C code to create
a generic fucntion.
* src/gauche-init.scm: load object system as well.
* src/main.c: adapted to the changes of load.c and core.c.
redesigned command-line options.
* src/load.c: current dir is not added to the load-path by default.
it's also up to the application.

initfile is up to the application.
* src/list.c: Scm_Delete added.
2001-03-23 Shiro Kawai <shiro@scherzo>
* release 0.2.9
* lib/*: reorganized library structure. gauche-specific stuff
go into gauche/ subdirectory, and can be used by
"(use gauche.something)".
* src/class.c, src/gauche/class.h: changed ScmClassAccessor to
ScmSlotAccessor and made it have more information for slot
initialization and access. Basic features such as defining
class in Scheme, instancing it, and accessing slots, start
working---a lot has to be done for completeness.
* src/compile.c (compile_qq_list): fixed a bug that messed up
the stack by quasiquoted forms with unquote and unquote-splicing
intertwined.

2001-03-19 Shiro Kawai <shiro@scherzo>
* release 0.2.6
* src/gauche.h, src/proc.c, src/class.c: changed procedure
structure. there's no longer separate classes for closure and
subr; they're <procuedure>. "type" field in ScmProcedure structure
discriminates closures, subrs, and other applicable metaobjects.
* src/vm.c: method dispatching code is embedded in VM loop. Not
quite working, but it's on the way.
