Lexer

The tree-sitter lexer handles syntax analysis and reports:

• Syntax errors
• Missing nodes
• Invalid token sequences

auto_lsp requires a valid Concrete Syntax Tree (CST) from tree-sitter to generate an AST.

Automatic errors

During AST construction, auto_lsp automatically detects and reports errors:

There are 2 types of errors:

• Missing Fields: Occurs when required fields in an AST node aren't matched by the query

• Query Mismatch: Happens when query captures don't align with the AST structure.
