Unreleased

v0.18.1: 28 December 2023

Improvements

  • Variables defined in ex_unit test, setup and setup_all context are now returned by completions provider. Navigation to variable definition and references now also works correctly
  • Suggest spec code lens now emits specs for all arity variants when function has default arguments. Previously only the one with all parameters was emitted
  • Missing required OTP :crypto module is now detected on startup
  • Completions provider is now properly returning quoted remote calls. Previously accepting a suggestion would insert invalid code

Fixes

  • Fixed regression and crash on phoenix-heex files. This problem was introduced in v0.18.0 and broke completions, definition and hover
  • Fixed a crash during struct field inspection when the struct cannot be instantiated
  • Fixed a crash in implementations provider when behaviour implementation is a delegate or a guard
  • Fixed a crash on invalid delegate AST node
  • Fixed a crash when incorrect AST resulted in mismatched alias stack pop operations
  • Fixed a crash on older elixir versions when compiler diagnostic message is not a binary. This problem was introduced in v0.18.0
  • Fixed invalid argument passed to fallback implementation for Apply spec code action
  • Workspace symbols provider now correctly navigates to functions with default arguments

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 actionsGustavo Aguiar

Improvements

  • Diagnostic provider returns deprecated and not used tags on certain warnings. This allows editors for visually marking code ranges using deprecated APIs and not used code constructs
  • Diagnostics are now stored along with document version. Diagnostic publishing algorithm has been improved to prefer recent parser diagnostics over stale build diagnostics.
  • Parser is now able to provide diagnostics in untitled: schema files based on languageId document property
  • On type formatting and Folding ranges providers are now disabled on eex documents as eex was never supported in those providers
  • OTP 26 compatibility warning on Windows updated to direct users to install 26.2+ version
  • Struct field completions now work on functions returning remote type sarah kate
  • Type inference from guard expressions added Nguyễn Văn Đức

Fixes

  • Fixed crash in document symbols provider on invalid attribute nodes
  • Fixed crash on cases where some compiler generates diagnostics with invalid position
  • Fixed test lense provider on code using Elixir proxy
  • Fixed debugger crash when stacktrace frame returns undefined instead of arguments list
  • Improved LSP compatibility on document synchronization. Previously the document version after applying changes was increased. This bug was present since the initial code release but started causing issues with discarded diagnostics in Helix editor since v0.17.0 started publishing diagnostics with document version
  • Fixed invalid result returned from build process when handling error during project reload

Potential incompatibilities

  • elixir_ls_debugger app has been renamed to debug_adapter to better reflect that it is not a debugger but an adapter implementing Debug Adapter Protocol. Similarly, the launch scripts has been renamed to debug_adapter.sh and debug_adapter.bat respectively. Editor extensions and custom launcher scripts may need an update

v0.17.10: 19 November 2023

Improvements

  • Improved validation of language server configuration
  • Improved validation of debugger launch configuration
  • Diagnostics with no file are now emitted on mix.exs. Previously they were skipped

  • Added missing clauses handling function call expansion in type inference engine

v0.17.6: 2 November 2023

Improvements

  • Bring back partial support for elixir 1.12. Note that it's best effort and not all features will work
  • Directory issues with fish launch script fixed Jamin Thornsberry
  • RTX activation in launch script now uses env -s instead of activate Walton Hoops
  • Language server is now more resilient when cwd changes. Workaround added for elixir issue when Path.expand would unnecessarily evaluate File.cwd!
  • Tracer should now be able to recover when DETS files are corrupted
  • elixir_sense plugin crash is now handled and should not prevent completions

Fixes

  • Fixed crash in debugger when on_load fails during module interpreting
  • Fixed crash in completions due to missing regex escapes
  • Fixed crash in document symbols on invalid typespec
  • Fixed crash in test code lense when test block cannot be found
  • Launch script properly uses custom Mix.install. This error made it fail on elixir 1.16. Not e that elixir 1.16 is not yet supported
  • Fixed crash in type inference incorrectly matching on typespec with arguments
  • Fixed crash in completions when callbacks from typespecs do not match those from docs

v0.17.5: 31 October 2023

Improvements

  • Invalid environment variables config is now raised as message. Previously it would crash the server
  • Compile tracer is more error tolerant. It should now handle invalid DETS files and missing directories
  • Dialyzer is more error tolerant - it should now be able to recover from broken beam files on elixir 1.14+

Fixes

  • Fixed crash when mix is unable to load deps. Loading of deps should now emit diagnostics
  • Fixed crash in complete when editing a map/struct
  • Fixed a crash in parser on untitled: schema files
  • Fixed a crash when emitting diagnostics and cwd is not present

v0.17.4: 30 October 2023

Improvements

  • Dialyzer will now store beams in separate directories for each elixir/OTP combo. This should limit number of errors due to beam errors
  • Debugger will now use current directory if projectDir is not set. This makes it easier to setup in folderless configuration

Fixes

  • All references to Mix.Project moved under a build lock or made go through cache. This should improve stability during build when Mix.Project stack changes
  • Fix error prone usages of String.starts_with? as a way of checking if file is in directory
  • Language server made more stable with autoBuild disabled

v0.17.3: 24 October 2023

Fixes

  • Fixed crash when language server tried to respond to cancelled requests. The bug was longstanding but changes from v0.17.2 exposed it

  • Fixed a problem when old diagnostics would not be cleared after server restart

v0.17.1: 13 October 2023

Fixes

  • Fixed a crash when emitting a diagnostic during file edit

v0.17.0: 11 October 2023

Highlights

  • Language Server now emit parser errors and warnings on type in .ex, .exs and .eex files
  • Language Server provides better completions for elixir reserved words. Thanks Kevin Kalb for initial work
  • Debugger now automatically breaks on Kernel.dbg macro. This allows inspecting variables, evaluating expressions and stepping through piped function calls. A setting breakOnDbg defaulting to true can be used to turn off that behaviour
  • Progress reports and cancel support added in debugger. This can be used to terminate long running evaluate requests.
  • Improved rendering of documentation in hover provider
  • Improved support for Unicode identifiers and atoms. Elixir supports Unicode identifiers since v1.5 and now all ElixirLS features should work with them

Improvements

  • Added support for fish shell Sergey Kislyakov
  • Consistently render parens for basic types in Suggest Contracts Code Lense and markdown
  • Debugger should now be better at handling some common crashes
  • Debugger now optimistically translates erlang versioned variable names to elixir names
  • Debugger emits better warnings when modules cannot be interpreted
  • Debugger can be launched with "noDebug": true. This allows Run Without Debugging in VSCode
  • Debugger will now emit exit code via exited DAP event. This allows tracking mix task result in debug session e.g. when running tests
  • New setting added to debugger exitAfterTaskReturns, defaulting to true - controls wether to end debug session when mix task returns
  • Language server will now reset cwd to project root after interrupted build
  • All ElixirLS dependencies are now vendored and should not conflict with client project dependencies
  • ElixirLS unloads deps used during startup and compilation
  • *nix launch scripts has been refactored and split into dedicated bash, fish, zsh Florian Neumann
  • A workaround for elixir formatter accidentally compiling the project has been implemented
  • Language fences added in complete/signature/hover provided markdown fragments
  • Language server stability should be improved by unloading project's applications. This works around elixir not updating application controller state after recompilation
  • Completions provider is now able to suggest keyword params on macros. Previously only functions was supported
  • Added float to list of bitstring modifiers in completions provider

Fixes

  • Debugger will not allow mix task with a /
  • A bug preventing do completion when there's a whitespace after cursor has been fixed
  • Document symbol provider will not crash when unable to get selection location for AST node
  • Signature provider now highlights the correct parameter in calls with default arguments when default arguments are not after required ones
  • Completions now work correctly after Unicode characters
  • Do not error if client returns null to workspace/configuration reverse request
  • Fixed a crash when getting a parameter name from complex parameter type. This bug made completions on :pg module fail.
  • Fixed invalid aliases in scope inference when a submodule __MODULE__.Some is used

Potential incompatibilities

  • Debugger will terminate the debug session and return result code when mix task returns. Previously, debugger would continue running. If the new behavior is not wanted, please set exitAfterTaskReturns to false in your launch configuration
  • debugExpressionTimeoutMs debugger launch configuration setting no longer has any effect. DAP cancel request can now be used to terminate long running debugger evaluate requests.
  • Debugger will now auto break on Kernel.dbg macro. If this is not intended consider setting breakOnDbg to false in your launch configuration

v0.16.0: 19 August 2023

Highlights

  • Added support for rtx version manager.
  • Language server now returns diagnostics in config files for current configuration. Previously when there were compilation errors in config files an error with stacktrace would be returned on mix.exs instead of the config file.
  • Configuration management has been refactored and migrated to pull based approach. This addresses recent problem on VSCode when the server would start with default settings after a restart. Pull based workspace/configuration request has been added in LSP 3.6 and the pull based workspace/didChangeConfiguration with params is deprecated.
  • Language server now uses call arity in definition, implementation, references and hover providers. This means that if there are multiple arity variants, the documentation for correct ones will be presented. In case of incomplete code all variants with arity greater or equal to the number of arguments are considered.

Improvements

  • Debugger is now able to set breakpoints in multiple modules in case one line maps to many modules
  • Completions provider will now trigger signature help when accepting a completion with 0-arity function when there higher arity versions available.
  • Completions provider will now trigger signature help when accepting a completion with a typespec of arity greater than 0.
  • Mix project modules pruning is more robust. This should address some rare crashes e.g. when deps directory is removed during a build.
  • Logger interception is more robust. This should address some rare crashes observed on elixir 1.15.
  • Install script no longer unnecessarily starts and stops applications. This should improve launch time.
  • On Unix systems launch script now uses SHELL environment variable to decide if it should prefer bash or zsh. Previously, bash was preferred.
  • Providers now rely on parser token_metadata when determining module and functions scopes. This allows for more accurate suggestions. Previous implementation was not able to provide module attribute completions inside module body when there were defs after the cursor.
  • Language server now provides documentation for builtin module attributes in hover and completions providers Nguyễn Văn Đức.
  • Hover provider returns documentation on reserved words and variables.
  • References provider is now able to find references to functions and module in current file. Previously only compiled modules were scanned for references.
  • Hover provider returns simple documentation for functions, typespecs and modules from the current file. Previously nothing was returned and a crash was logged.
  • Completions provider returns signatures for typespecs defined in current file.
  • Improved handling of defs with default params in signature help. Now only head signature is returned.
  • Language server is now able to provide signatures from behaviour or protocol in many cases.
  • Definition and references provider are now able to return result on variable remote calls when variable is known to be a module.
  • References provider is now able to track variable references outside of modules.
  • Improved type inference when variable is reassigned.
  • Providers consider local macros only after definition. This should improve correctness and reduce number of invalid completions.
  • Improved handling of alias and require with warn: option.

Fixes

  • Fixed crash in debugger when setting a function breakpoint on not existing function
  • Setting breakpoints in Inspect protocol implementations is now forbidden. This protocol is used internally and hitting a breakpoint resulted in deadlock.
  • Debugger no longer interprets JsonV.Encoder protocol (a vendored version of Json.Encoder) used internally.
  • Fixed a case when completions provider would return only 1 variant of a function with multiple arities.
  • Completion and signature providers correctly return multiple @spec clauses. Previously only the first one was formatted properly.
  • Changing settings no longer results in notification about changed mix target.
  • ELS_ELIXIR_OPTS environment variable was not correctly word split when passed to elixir command.
  • Fixed a crash when launching debugger with default mix task (equivalent of running mix).
  • Completions provider suggests aliased structs after % Nguyễn Văn Đức
  • Completions provider no longer returns @@.
  • Fixed a crash in completion provider when type in callback matched local without parens.
  • Improved Mix.Task module subtype detection. Previously are submodules of Mix.Tasks were considered. Now only ones exporting run/1. This error resulted in unnecessary completions.
  • Fixed a case when completions provider would suggest additional edit with alias Elixir.
  • Fixed a case when completions provider would suggest Elixir.Elixir Nguyễn Văn Đức
  • Correctly return alias subtype in completions provider when suggesting an alias. Previously module was returned even if such module does not exist.
  • Completions provider suggests alias for all matched module parts. Previously only first match was considered.
  • Completions provider no longer suggests alias when the hint has more than one part. This means that additional edits with aliases will not be returned after Some.Module..
  • Type of pinned variables is now correctly inferred Nguyễn Văn Đức
  • Fixed AST parsing of protocol implementations without for:.
  • Fixed a case when definition provider was unable to locate variables inside multiline struct.
  • Implementation provider works with macrocallback implementations.
  • Fixed endless recursion when expanding use macro. This caused definition provider to hang when navigating to Kernel functions/macros.
  • Fixed rendering of docs for builtin typespecs.
  • Fixed a crash with definition provider over __MODULE__.
  • Fixed a case in AST parser when @spec or @callback would get overwritten. Now all definitions are collected.
  • Fixed rare crashes on elixir 1.15 with cursor over submodule of an attribute or variable.
  • Signature provider no longer reveals details of @opaque typespecs.
  • Fixed order of signatures in completions provider.
  • Fix signature render of erlang functions with multiple EIP48 documentation entries (e.g. :erlang.system_info/1).
  • Fixed render of callback signatures. Previously they were marked as @spec, now @callback or @macrocallback.
  • No parens locals are no longer treated as calls on elixir 1.15+.
  • Fixed cases when crash in AST parser would produce invalid metadata.
  • Fixed crash in completions with nested dot expression on elixir 1.15.
  • Fixed AST parsing when quote was used as variable.

Potential incompatibilities

  • The language server will get configuration workspace/configuration if the client supports it. Previously it relied on workspace/didChangeConfiguration notification.

v0.15.1: 29 June 2023

Improvements

  • This is the first release supporting OTP 26. Unfortunately due to bugs in OTP only 26.0.2+ is supported. See 886 and 923 for details

Fixes

  • Fixed crash when handling workspace/didChangeWatchedFiles when project_dir not yet set
  • ExUnit test tracer is now under build lock. This should fix crashes due tu race conditions
  • Fixed completion of remote calls matching locals without parens (e.g. Map.drop when drop is local without parens from ecto_sql) Milo Lee

v0.15.0: 20 June 2023

Improvements

  • This is the first release supporting Elixir 1.15. See 898 for details
  • Main distribution mode switched to Mix.install script. This allows running ElixirLS built with a correct combination of OTP and elixir. Previously used .ez releases suffered from numerous problems stemming from version incompatibilities (e.g. 193)
  • elixir_sense replaced many of its custom source parsing internals with elixir 1.13+ Code.Fragment APIs
  • require and import are now understood by elixir_sense. This improves accuracy of definition, hover, references and complete providers. For example only imports matching only and except options will now be suggested by complete provider.
  • When accepting a completion with a not required macro a require directive will be now added to module.
  • Reimplemented use macro expansion. This should improve accuracy.
  • Better handling of typespecs in elixir_sense. This should improve accuracy in modules with defs and types sharing the same name.
  • Added ability to pass command line options to elixir and erlang via ELS_ELIXIR_OPTS and ELS_ERL_OPTS. This allows for setting a node name and connecting remotely to language server and debugger.

Fixes

  • Fixed a longstanding bug with formatter not respecting .formatter.exs when code is compiling (requires elixir 1.15) Thomas Depierre
  • Fixed invalid alias handling with submodules

Breaking changes and deprecations

  • Silence output from dialyxir making client disconnect from the server on elixir < 1.14
  • Avoid serializing PID to JSON

v0.14.4: 20 April 2023

Fixes

v0.14.3: 17 April 2023

Fixes

v0.14.2: 15 April 2023

Fixes

  • Print correct version

v0.14.1: 14 April 2023

Fixes

  • Reorder startup sequence to avert mix crash

v0.14.0: 14 April 2023

Improvements

  • Doctests can now be run via Test UI Carl-Foster
  • Fixed completions of records defined in the same file
  • Fixed support for alias __MODULE__
  • Silent crashes in dialyzer fixed

  • Debugger now properly tracks running processes. Previously UI was not updated when new processes start or running not monitored processes exit
  • Debugger now respects MIX_TARGET environment variable
  • Undefined function diagnostics no longer emitted from mix.exs dependencies. Elixir mix swallows those warnings since 1.10
  • Builds now use --all-warnings flag on mix compile. This should result in more predictable diagnostics in umbrella apps.
  • Completion provider returns typespecs for struct properties in documentation if struct module defines type t()
  • Debugger now returns type of breakpoint in the hit event as required by DAP
  • Fixed crash when elixir-ls is run in a directory without mix.exs
  • References provider now can find references to elixir modules. Previously modules were found only when a function or macro from that module was called
  • Typespecs from behaviour module are used on callback implementations in completions, hover and specification providers
  • @after_verify attribute added in elixir 1.14 is recognized as builtin
  • Fixed edge cases when private def would overshadow a public one
  • Quoted expressions are now skipped when code AST is analyzed. There is low chance anything useful can be extracted from them
  • Submodule implicit alias behavior is now correctly implemented. This should improve quality in various providers
  • Fixed crash in references provider when reference does not have a line (e.g. in phoenix live views)

Refactorings

  • Mix Formatter now properly formats elixir-ls code from the top directory
  • Major refactoring of elixir-ls server driven by Steve Cohen is under way. It's not yet complete and can be tested by enabling experimental server. Thanks to others involved (Scott Ming, Samuel Hełdak)
  • Language server now runs with consolidated protocols. Consolidation is disabled on each build with --no-protocol-consolidation flag on mix compile. This should make the server faster. The side effect is more protocol consolidation warnings printed to the console on elixir < 1.14.

Deprecations

  • This is the last release supporting elixir 1.12

  • Fix Dialyzer crash when some modules are undialyzable

  • Change default settings to automatically trim trailing whitespace and add newline at end of file

  • Fix autocomplete not firing after "."

v0.2.8: 29 Nov 2017

  • Add auto-indentation rules (copied from 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)

  • Automatic dialyzer server in Erlang/OTP 20
  • Lots and lots of refactoring

v0.0.9: 23 Jun 2017

  • Enable setting breakpoints in Erlang modules

v0.0.7: 12 Jun 2017

v0.0.5: 11 Jun 2017

  • Began a changelog :)
