Snapshot release 2022-11-15

Mostly for bug fixes, some of which are annoying.
The snapshot period will be slowing down if there are no interesting changes or big bug fixes.

New features:

• Document links. textDocument/documentLink

  Valid relative paths, URLs and flake references now report
  as links. For VSCode, it's shown as underlined text, and a
  hand-shaped cursor is shown when moving over them.
  Ctrl-Click would open the target file or URL.

• Store Attr source information in types.

  It is not quite useful for now, and is only be used by the
  "completion kind" during completion.
  We'll find a way to support goto-definition for it in the future.

Fixes:

• Fixed type inference for if conditions.
• Fixed errors from client exit monitor.
• Fixed a deadlock that occurs when changing text rapidly.

Snapshot release 2022-11-07

New features:

• Initial type system implementation with inference.

  The design is a modified Hindley–Milner type system.
  Polymorphism is not yet implemented, and poly-lambdas like a: a
  would currently fail with the result ? -> ?.

  With the help of Attrset types, we can now support more completion
  places.

• Type signatures are rendered in hover messages.

• Field completions.

  Completions in both reference and definition sites are supported,
  when the type information is enough.

  let
    f = { foo }@bar: bar.|; # -> foo. Reference site.
  in f {
    f| # -> foo. Definition site.
  }

  It can also self-complete in let or Attrsets.

  {
    some.deep.setting = 42;
    some.d| # -> deep
  }

Fixes:

• Force exit the server when the client process died. (Linux)
• Enhance parser error recovery.

Weekly release 2022-10-03

New features:

• Multi-threading.
• LSP request cancellation.
• Report duplicated lambda parameters.
• Goto-definition for non-Nix file paths.

Fixes:

• Multiple workspaces now work well.
• Mis-synchronization when creating new files is now fixed.
• Suppress unhandled notification errors with VSCode and Nix IDE.

2022-09-26

New features

• Renaming now supports names involving inherit.

  • Renaming identifiers inside inherit will change the definition, and
    foo: { inherit foo/* -> new */; }
    =>
    foo: { new = foo; }

  • Renaming identifiers outside inherit will change references.
    foo/* -> new */: { inherit foo; }
    =>
    new: { foo = new; }

• Show documentations during completion for builtins.

  Currently only global builtins like map are supported.
  The documentations are generated from Nix at build-time, and some
  builtins don't have upstream documentations.

• Hover. textDocument/hover

  • Show documentations for global builtins.
  • Show the kind of names, like let-bindings, parameters, or etc.

• Syntax errors are now shown by default.

• Custom diagnostics filter.

  See docs/features.md for more information.

• Symbol hierarchy, aka. outline. textDocument/documentSymbol

• File formatting via external command. textDocument/formatting

Fixes

• Contextual keyword or are now semantically highlighted correctly.
• Parser error recovery is improved, and error messages are tweaked to be
  more helpful.

2022-09-19

New features

• Semantic highlighting textDocument/semanticTokens/{range,full}.
• Catch panics in request handlers and show messages to LSP clients.
• Incremental change notification handling for textDocument/didChange.

Fixes

• Load only .nix files in workspace. This could speed up workspace loading.
• Remove unmaintained ansi_term from dependency tree.
