ocaml-cmark is an OCaml interface for the cmark CommonMark parsing and rendering library.
Before installing this, you must install cmark.
All the parsing and rendering functions should be implemented.
The interface is pretty simple. Check out src/cmark.mli.
Functions for examining, modifying, and iterating over node data are not yet implemented.
They shouldn't be hard to do, just tedious.
To build, you will need to install car, a collection of ocamlbuild aliases.
Then you can install via OPAM with:
opam pin add cmark .
Alternatively you can install using car:
car lib
