cmarkit — CommonMark parser and renderer for OCaml

%%VERSION%%

Cmarkit parses the CommonMark specification. It provides:

• A CommonMark parser for UTF-8 encoded documents. Link label resolution can be customized and a non-strict parsing mode can be activated to add: strikethrough, LaTeX math, footnotes, task items and tables.

• An extensible abstract syntax tree for CommonMark documents with source location tracking and best-effort source layout preservation.

• Abstract syntax tree mapper and folder abstractions for quick and concise tree transformations.

• Extensible renderers for HTML, LaTeX and CommonMark with source layout preservation.

Cmarkit is distributed under the ISC license. It has no dependencies.
