katex_parser/
lib.rs

1//! A Rust port of the KaTeX parser: lexes and parses LaTeX math expressions
2//! with macro expansion into a typed [`ParseNode`] AST, and renders that AST
3//! to Unicode text.
4//!
5//! The parser mirrors the MoonBit `katex-parser` package (itself a port of
6//! [KaTeX](https://katex.org)). Entry points:
7//!
8//! - [`parse`] / [`parse_with_specs`] — parse LaTeX into a `ParseNode` list.
9//! - [`render`] — render a parsed node list as Unicode text.
10//! - [`Settings`] — parser configuration (display mode, macros, strictness,
11//!   trust policy, and a persistent macro store).
