`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 aims for compliance with the [CommonMark](https://commonmark.org/) standard.
We are currently compliant with [0.30 of the ComonMark
spec](https://spec.commonmark.org/0.30/).

Omd is developed on GitHub. If you need to report an issue, please do so at
https://github.com/ocaml/omd/issues.

Installation
------------

The recommended way to install `omd` is via the [opam package manager][opam].

You can install versions published to opam with:

```sh
$ opam install omd
```

You can install the current development version from the GitHub repository with

```sh
$ opam pin [email protected]:ocaml/omd.git
```

Documentation
-------------

- View API docs online: https://ocaml.github.io/omd
- View the API docs locally: `odig doc omd`

Building from source
--------------------

You can also build it manually from source with:

```sh
$ git clone https://github.com/ocaml/omd.git
$ cd omd
$ make build
```

You can run the test suite with

```sh
$ make test
```

Dependencies
------------

The minimum version of OCaml required is 4.13.

Dependencies are tracked in the [dune-project](./dune-project) and can be
installed by running:

```sh
$ opam install . --deps-only
# or
$ make deps
```

History
-------

Omd 1 was developed by [Philippe Wang](https://github.com/pw374/) at [OCaml
Labs](http://ocaml.io/) in [Cambridge](http://www.cl.cam.ac.uk).

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](https://opam.ocaml.org) exists.

- We wanted to provide a way to make the contents of the
[OCaml.org](http://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](http://www.openmirage.org)
application. Note that OMD has replaced the previous Markdown parser of
[COW](https://github.com/mirage/ocaml-cow), which has been developed as part
of the Mirage project.

Omd 2 started development in 2020, beginning [Nicolás Ojeda
Bär](https://github.com/nojb)'s redesign and rewrite, and is currently ongoing.
Omd 2 has yet to reach feature parity with Omd 1.
