# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).

## [Unreleased]

## [0.3.0] - 2019-09-05

### Added

* Add support for decoding the optional `Content-Type` field in messages.
* Implement support for the following client-to-server messages:
  * `workspace/didChangeWorkspaceFolders`
  * `workspace/didChangeConfiguration`
  * `workspace/didChangeWatchedFiles`
  * `workspace/symbol`
  * `workspace/executeCommand`
* Implement support for the following server-to-client messages:
  * `telemetry/event`
  * `client/registerCapability`
  * `client/unregisterCapability`
  * `workspace/applyEdit`

### Changed

* Bump minimum Rust version to 1.34.0.
* Rename `highlight()` to `document_highlight()` to better match the
  specification.
* Make all notification methods into provided methods (PR #34).
* Change `LspService` request type from `String` to `Incoming` (PR #28).
* Update `Server` to spawn services with `Incoming` request type.
* Use `env_logger` to print log messages in examples.

### Fixed

* Fix broken doc link to `textDocument/didChange` in `LanguageServer` trait.

## [0.2.0] - 2019-09-03

### Added

* Add `ExitedError` for when calling `LspService` after it has already exited.

### Changed

* Language server now returns server error code `-32002` if any method is called
  before `initialize` request is received, [as per the spec][init].
* `LspService` sets `Service::Error` to `ExitedError`.
* `Server` can now accept any service where `Service::Error` is convertible to
  `Box<dyn Error + Send + Sync>`. This enables compatibility with most Tower
  middleware.
* Retain error or success from future in `ExitReceiver::run_until_exit()`.
* Remove `'static` bounds on some `Server` and `ExitReceiver` methods.
