tree-sitter-csv

The CSV grammar used by Blue CSV.

Nodes

• file — top-level.
• row — one record.
• field_1 .. field_10 — positional wrappers for the first ten cells in a row. Each wraps a quoted_field or unquoted_field. Positional nodes drive rainbow-column highlighting.
• field_overflow — every cell past the tenth in a row, same wrapper shape.
• quoted_field — double-quoted, supports escaped quotes ("") and embedded newlines.
• unquoted_field — everything else up to the next ,, \r, or \n.

Build

npm install
npm run generate
npm test

Prior art

tree-sitter-grammars/tree-sitter-csv is a generic CSV grammar with a single field node type. This one diverges by emitting field_1..field_10 / field_overflow so rainbow-column highlighting works through tree-sitter queries alone, without runtime column counting.
