omd: Markdown library and tool in OCaml
Omd is an OCaml library designed to parse, manipulate, and print Markdown into different formats. In addition to the library, a command-line tool
omd is included to easily convert markdown into HTML.
Omd is developed on GitHub. If you need to report an issue, please do so at https://github.com/ocaml/omd/issues.
The recommended way to install
omd is via the [opam package manager][opam].
You can install versions published to opam with:
$ opam install omd
You can install the current development version from the GitHub repository with
$ opam pin email@example.com:ocaml/omd.git

Building from source
You can also build it manually from source with:
$ git clone https://github.com/ocaml/omd.git $ cd omd $ make build
You can run the test suite with
$ make test
The minimum version of OCaml required is 4.13.
Dependencies are tracked in the dune-project and can be installed by running:
$ opam install . --deps-only # or $ make deps
Its development was motivated by at least these facts:
We wanted an OCaml implementation of Markdown; some OCaml parsers of Markdown existed before but they were incomplete. It's easier for an OCaml project to depend on an pure-OCaml implementation of Markdown than to depend some interface to a library implemented using another language, and this is ever more important since Opam exists.
We wanted to provide a way to make the contents of the OCaml.org website be essentially in Markdown instead of HTML. And we wanted to this website to be implemented in OCaml.
Having an OCaml implementation of Markdown is virtually mandatory for those who want to use a Markdown parser in a Mirage application. Note that OMD has replaced the previous Markdown parser of COW, which has been developed as part of the Mirage project.
Omd 2 started development in 2020, beginning Nicolás Ojeda Bär's redesign and rewrite, and is currently ongoing. Omd 2 has yet to reach feature parity with Omd 1.
