Snapshot release 2023-04-03

Features

• Code actions about string rewriting. (#69)

  • quote_attr and unquote_attr to quote/unquote attributes in
    attrset or let-in.
  • rewrite_string_to_indented and rewrite_indented_to_string to
    rewrite between two string styles.
  • rewrite_uri_to_string to rewrite deprecated URI literals into
    strings.

• Completion for NixOS options.

  This requires a working Flake setup, which has an input named
  nixpkgs for the source of NixOS options. It must be a relatively
  recent version of github:NixOS/nixpkgs. If you have multiple nixpkgs
  in your inputs, you can create an alias inputs.nixpkgs.follows = "the-input-to-use" to select one.

  If it's correctly recognized and evaluated, any NixOS-module-like Nix
  files will get completions and type information for NixOS options.

  For example:

  { ... }:
  {
    nix.settings.|  # -> allowed-users, auto-optimise-store, ...
  }

• The LSP server now reports server name nil and its version (if any)
  to the client through serverInfo during initialization.

Fixes

• Parsing errors when ' appears in indented strings.
• Panics when a flake input is named self.
• Unescaped identifiers and/or attributes in completions.
• Recognition of flake.nix when rec { ... } is used in top-level.
