Build and Deploy Verso / deploy (push) Has been cancelled
Replace the StreamLanguage tokenizer with a full LR grammar compiled by
@lezer/generator, giving Typst the same parse-tree infrastructure that
LaTeX and BibTeX already use.
Grammar features:
- Headings (=, ==, …) via SOL-detecting external tokenizer
- Code expressions (#keyword, #func(args), #ident.method, #{…}, #[…])
- Named argument highlighting (key: value in function calls)
- Inline and display math ($…$)
- Strong (*…*) and emphasis (_…_) with bold/italic formatting
- Raw blocks (```lang…```) and inline raw (`…`)
- Nested block comments (/* /* */ */) via depth-tracking external tokenizer
- Labels (<name>) and references (@name)
- Backslash escapes
Infrastructure changes:
- lezer-typst/typst.grammar — new Lezer grammar
- lezer-typst/tokens.mjs — external tokenizers for context-sensitive lexing
- scripts/lezer-latex/generate.mjs — Typst added to grammars array so the
existing lezer-latex:generate script (and Dockerfile step) compile it
- .gitignore — generated typst.mjs / typst.terms.mjs excluded from git
