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 parsed document: the green tree plus any syntax errors gathered alongside it. Errors never abort the parse (see AGENTS.md, Core decision #5).

SyntaxError

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

Functions

parse

Parse LaTeX source into a lossless CST.

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.
