### Unreleased

### v0.20.0: 21 February 2024

#### Highlights

- Selection ranges provider added. This provider handles expand/shrink selection editor commands in a semantic aware way
- Completions, hover and signature help providers now are able to display `@doc` and other attributes data from the currently edited buffer
- Hover provider now returns markdown with working links to hexdocs and erlang documentation. Support for [ExDoc autolinking](https://hexdocs.pm/ex_doc/readme.html#auto-linking) and [erlang see tags](https://www.erlang.org/doc/apps/erl_docgen/inline_tags#%3Csee*%3E---see-tags) has been added

#### Improvements

- ElixirLS updated to [v0.20.0](https://github.com/elixir-lsp/elixir-ls/blob/master/CHANGELOG.md#v0200)
- Quoted atoms and calls are now treated as unbalanced bracket scopes
- Improved syntax highlighting of underscored typespecs and typespecs without parens. Previously those were matched as `comment.unused.elixir`, `variable.other.readwrite.elixir`, `entity.name.function.call.local.elixir`. A scope `meta.type.definition.elixir` has been introduced

### Breaking changes and deprecations

- Typespecs are now matched as `entity.name.function.typespec.elixir`. Previously those would match as `comment.unused.elixir`, `variable.other.readwrite.elixir` and `entity.name.function.call.local.elixir`

### v0.19.0: 21 January 2024

#### Highlights

- Test UI is now able to run multiple tests at once. This is made possible with running `mix test` command via debug adapter with a custom ExUnit formatter streaming test suite progress via DAP output events. Running multiple tests is supported on workspace folder, file, module, describe blocka and doctest level
- On type parsing and diagnostics for phoenix `.heex` files
- Workspace symbols provider has been reimplemented. Previously the workspace symbols index was build from all available symbols. To make it more focused and helpful now only symbols from the project are considered. This change made it much quicker and improved the quality of returned results. Fuzzy matching engine was also improved and made consistent with how complete provider works.

#### Improvements

- ElixirLS updated to [v0.19.0](https://github.com/elixir-lsp/elixir-ls/blob/master/CHANGELOG.md#v0190)
- Added highlighting of matching `do|fn` `end` pairs. This was added in v0.15.0 and reverted in v0.15.1. The previous attempt broke on `do:` and other atoms. This problem is now resolved with `constant.language.symbol.elixir` added to unbalanced scopes
- Added highlighting of matching `<<` `>>` pairs. This was added in v0.15.0 and reverted in v0.15.1. The previous attempt broke on bitwise operators. This problem is now resolved with `keyword.operator.bitwise.elixir` and `keyword.operator.other.unbalanced.elixir` added to unbalanced scopes
- Tests are no longer run with with `--raise` flag
- Test UI now renders separate doctests making it possible to run or debug them separately
- Charlists are now classified as `string.quoted.single.elixir` instead of `support.function.variable.quoted.single.elixir`. The previous class was breaking brackets matching algorithm. VSCode treats strings as unbalanced scopes.

#### Fixes

- Test UI is able to correctly run tests with file filter on Windows. This works around https://github.com/elixir-lang/elixir/issues/13225
- Test UI now finds tests of types other that `test` and `doctest`. Previously the filtering was too aggressive

### Breaking changes and deprecations

- Tests are now always run through debug adapter (with or without `noDebug` flag)
- Charlists are now classified as `string.quoted.single.elixir` instead of `support.function.variable.quoted.single.elixir`. The previous class was breaking brackets matching algorithm. VSCode treats strings as unbalanced scopes.
- `~>>` `<<~` operators are now classified as `keyword.operator.other.unbalanced.elixir` instead of `keyword.operator.other.elixir`

### v0.18.1: 28 December 2023

#### Improvements

- ElixirLS updated to [v0.18.1](https://github.com/elixir-lsp/elixir-ls/blob/master/CHANGELOG.md#v0181)
- Syntax highlighting now correctly matches quoted remote calls (`Mymod."4quo\"ted"()` is valid elixir syntax)

### v0.18.0: 22 December 2023

#### Highlights

- Elixir 1.16 support
- Diagnostics provider now returns related info with code positions. This feature works best with elixir 1.16 allowing for navigation to invalid syntax elements like mismatched brackets
- On type parser has been improved and extended. It now keeps a cache of parsed AST and extracted document metadata. Most of the providers has been updated to reuse this metadata eliminating the need for on demand parsing. This should make completions, hover, etc more snappy. The previous implementation was particularly not efficient for completions provider that would parse the file twice for each request
- Phoenix integration improved. Go To Definition can now navigate to controllers when inside a Phoenix scope. Complete suggestions in Phoenix.Router now return controllers and actions[Gustavo Aguiar](https://github.com/gugahoa)

#### Improvements

- ElixirLS updated to [v0.18.0](https://github.com/elixir-lsp/elixir-ls/blob/master/CHANGELOG.md#v0180)
- Added suggested configuration for `eex` files
- Test UI will no longer look for test files in directories starting with `.`

#### Fixes

- Grammar updated - fixed dot access matched as function call. This regression was introduced in v0.17.1
- Grammar updated - fixed punctuation not matched in atoms and attributes. This regression was introduced in v0.17.0
- Restart command refactored. Previously it would fail to restart a failed language server client

### v0.17.1: 13 October 2023

- Consistently match modules. Previous rules matched them differently in `defmodule`

### v0.17.0: 11 October 2023

#### Highlights

- Syntax highlighting for Unicode identifiers. Elixir supports Unicode identifiers since v1.5 and now all ElixirLS features should work with them
- When running a debug session from Test UI test result is now passed to the test controller and UI updates accordingly

#### Improvements

- ElixirLS updated to [v0.17.0](https://github.com/elixir-lsp/elixir-ls/blob/master/CHANGELOG.md#v0170)
- The extension is now bundled. This should improve startup time
- `defprotocol` and `defimpl` are now treated as modules in grammar

#### Fixes

- Task arguments are now correctly passed to debugger when starting debug session from Test UI. This bug made it impossible to debug a single test
- Fixed race conditions in Test Controller. Previously if Test UI was loaded before the language server starts the extension would error and fail to get the list of tests in project
- `env` from launch config is now correctly passed to debugger process in folderless setup (i.e. when launch config is bundled in workspace file)
- Bogus syntax highlighting rules matching function calls removed

### v0.16.0: 19 August 2023

#### Improvements

- ElixirLS updated to [v0.16.0](https://github.com/elixir-lsp/elixir-ls/blob/master/CHANGELOG.md#v0160)
- Migrated to pull based configuration retrieval and removed deprecated configuration sync. This addresses issues in recent VSCode versions when after restart the server would ignore client configuration.
- Improved handling of language server uninitialized state. This should make Testing UI more stable.

#### Fixes

- Fixed syntax highlighting with camelCase calls [Milo Lee](https://github.com/oo6)
- Debug now starts in the correct workspace folder. Previously the debug controller incorrectly assumed there is only one workspace.

#### Deprecations and removals

- `<<` and `>>` bracket matching has been removed. It broke syntax highlighting in modules using `<<<` and `>>>` bitwise operators.

### v0.15.3: 7 July 2023

No changes since v0.15.2. 0.15.2 failed to publish to Open VSX

### v0.15.2: 29 June 2023

#### Improvements

- ElixirLS updated to [v0.15.1](https://github.com/elixir-lsp/elixir-ls/blob/master/CHANGELOG.md#v0151) with support for OTP 26

### v0.15.1: 22 June 2023

### Fixes

- Revert `do` `end` bracket matching. This introduced too many problems and the workarounds did not work for `do:`
- Revert markdown highlighting in heredocs. `text.html.markdown` interferes with elixir grammar when a list (`*` or `-`) is present. Handling this would require a dedicated grammar for heredoc markdown.

### v0.15.0: 20 June 2023

#### Improvements

- ElixirLS updated to [v0.15.0](https://github.com/elixir-lsp/elixir-ls/blob/master/CHANGELOG.md#v0150)
- Added support for elixir 1.15 multi-letter sigils
- Added highlighting of matching `do` `end` pairs
- Treat code in heredocs as markdown. This allows syntax highlighting and delegation to markdown language server in `@moduledoc` `@doc` and `@typedocs`
- Highlight elixir code in `~L` sigil
- Improved handling of multi-root workspaces. Now language server is started in outermost workspace directories that contain `mix.exs`.
- Pass env from launch configuration to debugger. This allows setting node name for remote debugging (e.g. `"env": {"ELS_ELIXIR_OPTS": "--sname mynode"}`)

### Fixes

- Fixed not working syntax highlighting for `defguard` and `reraise`
- Reverted changes adding syntax highlighting in `.heex`. This conflicted with [Phoenix Framework extension](https://marketplace.visualstudio.com/items?itemName=phoenixframework.phoenix)
- `languageServerOverridePath` is correctly handled in debugger
- Consistently highlight `@moduledoc` `@doc` and `@typedocs` modifiers as documentation

### Refactorings

VSCode potentially breaking changes:
- Change language id to be lowercase kebab-case in accordance with [VSCode guidelines](https://code.visualstudio.com/docs/languages/identifiers#_new-identifier-guidelines). This also fixes an issue displaying the elixir logo for html.eex files. (thanks [Matt Furden](https://github.com/zolrath)) [#87](https://github.com/elixir-lsp/vscode-elixir-ls/pull/87)
  - This changes the language id's `EEx`->`eex` and `HTML (EEx)`->`html-eex`
  - If you have customized your emmet configuration configuration then you need to update it:
  - Open VSCode and hit `Ctrl+Shift+P` or `Cmd+Shift+P` and type `"Preference: Open Settings (JSON)"`
  - Add or edit your `emmet.includedLanguages` to include the new Language Id:
```json
"emmet.includeLanguages": {
  "html-eex": "html"
}
```

If you have eex file associations in your settings.json then remove them:
```
"files.associations": {
  "*.html.eex": "HTML (EEx)", // remove this
  "*.html.leex": "HTML (EEx)" // remove this
},
```

- Fix dialyzer checking files that have not changed which gives a good speedup [#165](https://github.com/elixir-lsp/elixir-ls/pull/165) (thanks [hworld](https://github.com/hworld))

VSCode:
- Change: No longer override default value of `editor.acceptSuggestionOnEnter` [vscode-elixir-ls [#53](https://github.com/elixir-lsp/vscode-elixir-ls/issues/53)](https://github.com/elixir-lsp/vscode-elixir-ls/pull/53)

- Add didSave to server capabilities (thanks to [Jonáš Trantina](https://github.com/Coffei)) [#86](https://github.com/elixir-lsp/elixir-ls/pull/86)

Potentially Breaking Changes:

- `language_server.sh` and `debugger.sh` run bash instead of `sh` (this is expected to break very few setups, if any) [#118](https://github.com/elixir-lsp/elixir-ls/pull/118)

### v0.2.28: 16 Nov 2019

- Fix debugger tasks not continuing to run on Elixir 1.9 (thanks to [joshua-andrassy](https://github.com/joshua-andrassy) for doing the legwork)

- Print PATH to developer console if "elixir" command fails
- Fix Dialyzer crash when some modules are undialyzable

### v0.2.20: 13 Jul 2018

### v0.2.18: 19 Mar 2018

- Fix autocomplete bugs when typing in parentheses
- Copy latest syntax highlighting from fr1zle/vscode-elixir
- Handle `subdirectories` and `import_deps` in `.formatter.exs`. Requires the latest Elixir (1.6.5), which you can install via kiex with `kiex install master` prior to its release.

- New feature: Automatically fetch deps when compiling. Set `elixirLS.fetchDeps` to `false` to disable
- New feature: Incremental text synchronization
- Minor improvements to autocomplete and automatic block closing

- ** ACCEPT AUTOCOMPLETE SUGGESTIONS WITH TAB INSTEAD OF ENTER.** See readme for an explanation of why. You can change it back if you really want.
- Change default settings to automatically trim trailing whitespace and add newline at end of file

### v0.2.14: 3 Mar 2018

- Fix failures to launch in some projects

- Fix builds and related features on Windows

### v0.2.9: 29 Nov 2017

- Fix autocomplete not firing after "."

### v0.2.8: 29 Nov 2017

- Add auto-indentation rules (copied from
  [fr1zle/vscode-elixir](https://github.com/fr1zle/vscode-elixir))
- Disable `editor.quickSuggestions` by default so autocomplete suggestions are
  triggered automatically only when after a ".". This is nice because the
  language server irritatingly tries to auto-complete things like "do" or "else"
  if they come at the end of a line.
- Add configuration option "mixEnv" to set the Mix environment used when
  compiling. It now defaults to "test" instead of "dev" to aid in TDD and to
  avoid interfering with the Phoenix dev server.
- Add configuration option "projectDir" for when your Mix project is in a
  subdirectory instead of the workspace root.
- Add debug launch configuration option "env" to set environment variables
  (including `MIX_ENV`)

  modules. This is important if for modules that contain NIFs which can't be
  debugged.

### v0.2.7: 9 Nov 2017

- Read formatter options from `.formatter.exs` in project root instead of
  including line length in extension config options

  and recoverable

### v0.2.5: 3 Nov 2017

- Improve error output in debugger and fix failures to launch debugger

### v0.2.4: 25 Oct 2017

- Package ElixirLS as .ez archives instead of escripts. This should make `asdf`
  installs work.

- Fix timeouts when calling back into the language server with build or dialyzer
  results

### v0.2.3: 24 Oct 2017

- Fix failing debugger launch
- Fix segfaults in OTP 20 caused by regexes precompiled in OTP 19

### v0.2.2: 19 Oct 2017

### v0.2.1: 19 Oct 2017

- Fix bug where deps are recompiled after every change
- Update README
- Update syntax highlighting (merged from fr1zle/vscode-elixir)

### v0.2.0: 17 Oct 2017

- Rewritten build system to make use of Elixir 1.6 compiler diagnostics
- Code formatting in Elixir 1.6
- Automatic dialyzer server in Erlang/OTP 20
- Lots and lots of refactoring

### v0.0.9: 23 Jun 2017

- Revert to building with Erlang OTP 19.2 instead of 20.0. It seems that
  escripts built with 20.0 won't run on 19.2 runtimes.
- Fix handling of Windows paths with non-default drive letter

### v0.0.8: 23 Jun 2017

- Enable setting breakpoints in Erlang modules

### v0.0.7: 12 Jun 2017

- Fix launching of debugger on OSX (when working directory is not set to the
  extension directory)

  (Fix in 0.0.6 didn't actually work)

### v0.0.6: 12 Jun 2017

- Handle Elixir installations that were done via the "asdf" tool

### v0.0.5: 11 Jun 2017

- Windows support

### v0.0.4: 10 Jun 2017

- Updated ElixirLS to package its apps as escripts and updated client to handle
  it. This should fix the error `(Mix) Could not start application language_server: could not find application file: language_server.app`.
  Windows, however, is still broken.
- Began a changelog :)
