Module core 

The parser entry point and its output type.

parse runs the pipeline: lex → [grammar::parse] (the recursive descent, which emits events + errors) → [build_tree] (the green tree). Syntax errors ride a side channel and never abort the parse.

Structs

Parse

A green tree and the syntax errors gathered while parsing it.

SyntaxError

A syntax error, carried on a side channel keyed by byte range.

Functions

parse

Parse LaTeX source into a lossless CST.

parse_with_declarations

Parse LaTeX source under an explicit LexConfig and a project’s declarations — the one input to the tree that is not the text (AGENTS.md decision #12).

parse_with_declarations_resolved

parse_with_declarations, additionally handing back the ParseCtx the returned tree was parsed under.

parse_with_flavor

Parse LaTeX source into a lossless CST under an explicit LexConfig.

reconstruct

Parse input and render the CST back to source. By the losslessness invariant this always equals input.
