tree-sitter-latex


This repo provides a LaTeX grammar for the tree-sitter parser generator.

Originally, this grammar is based off the parser of the texlab language server and primarily focuses on the constructs that are relevant for the language server.

This repository does not provide the accompanying highlighting definitions, instead they live in the nvim-treesitter repository.

To generate the parser, run

``
npx tree-sitter generate
`

after checking out the repository.

Limitations

As widely known, parsing LaTeX is Turing complete so there is no way to handle every construct in a tree-sitter` grammar. Instead, the grammar relies on a best effort approach while focusing on the LaTeX specific constructs like environments or sections instead of dealing with TeX internals like catcode.
