Release v0.17.0

on GitHub

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
