Add parameter highlights to Erlang This doesn't work robustly (within pattern matches). Only regular bindings are highlighted as parameters. In order to highlight all parameters even in matches, we would need an arbitrary nesting operator in queries which doesn't exist yet in tree-sitter. 2022-11-02 18:38:36 +04:00			`; Specs and Callbacks`

Update tree-sitter-erlang and highlights A few changes: * 0-arity type specs like the following previously would not have the expected 'variable.parameter' highlighting for the return type: -spec foo() -> Value when Value :: term(). * Highlight module, type and function docs as documentation comments and inject markdown into them. * Replace `#match?` predicates with `#any-of?` where possible. * Remove custom auto-pairs. Now that Erlang uses markdown for documentation, the asciidoc-style backtick-singlequote pair is no longer useful. 2023-04-14 20:41:20 +04:00			`pattern: (arguments (variable)? @local.definition)`
