recommonmark
************

A "docutils"-compatibility bridge to CommonMark.

This allows you to write CommonMark inside of Docutils & Sphinx
projects.

Documentation is available on Read the Docs:

Getting Started
===============

To use "recommonmark" inside of Sphinx only takes 2 steps. First you
install it:

   pip install recommonmark 

Then add this to your Sphinx conf.py:

   # for Sphinx-1.4 or newer
   extensions = ['recommonmark']

   # for Sphinx-1.3
   from recommonmark.parser import CommonMarkParser

   source_parsers = {
       '.md': CommonMarkParser,
   }

   source_suffix = ['.rst', '.md']

This allows you to write both ".md" and ".rst" files inside of the
same project.


Links
-----

For all links in commonmark that aren't explicit URLs, they are
treated as cross references with the ":any:" role. This allows
referencing a lot of things including files, labels, and even objects
in the loaded domain.


Linking to headings in other files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For linking to headings in other files you can use the
"autosectionlabel" sphinx feature, e.g.

   # conf.py

   extensions = [
       # Auto-generate section labels.
       'sphinx.ext.autosectionlabel',
   ]

   # Prefix document path to section labels, otherwise autogenerated labels would look like 'heading'
   # rather than 'path/to/file:heading'
   autosectionlabel_prefix_document = True

You would use it like:

   <!-- path/to/file_1.md -->

   # Title

   ## My Subtitle

   <!-- file_2.md -->

   [My Subtitle][]

   [My Subtitle]: <path/to/file_1:My Subtitle>


AutoStructify
-------------

AutoStructify makes it possible to write your documentation in
Markdown, and automatically convert this into rST at build time. See
the AutoStructify Documentation for more information about
configuration and usage.

To use the advanced markdown to rst transformations you must add
"AutoStructify" to your Sphinx conf.py.

   # At top on conf.py (with other import statements)
   import recommonmark
   from recommonmark.transform import AutoStructify

   # At the bottom of conf.py
   def setup(app):
       app.add_config_value('recommonmark_config', {
               'url_resolver': lambda url: github_doc_root + url,
               'auto_toc_tree_section': 'Contents',
               }, True)
       app.add_transform(AutoStructify)

See https://github.com/rtfd/recommonmark/blob/master/docs/conf.py for
a full example.

AutoStructify comes with the following options. See
http://recommonmark.readthedocs.org/en/latest/auto_structify.html for
more information about the specific features.

* **enable_auto_toc_tree**: enable the Auto Toc Tree feature.

* **auto_toc_maxdepth**: The max depth of the Auto Toc. Defaults to 1.

* **auto_toc_tree_section**: when True, Auto Toc Tree will only be
  enabled on section that matches the title.

* **enable_auto_doc_ref**: enable the Auto Doc Ref feature.
  **Deprecated**

* **enable_math**: enable the Math Formula feature.

* **enable_inline_math**: enable the Inline Math feature.

* **enable_eval_rst**: enable the evaluate embedded reStructuredText
  feature.

* **url_resolver**: a function that maps a existing relative position
  in the document to a http link

* **known_url_schemes**: a list of url schemes to treat as URLs,
  schemes not in this list will be assumed to be Sphinx cross-
  references. Defaults to "None", which means treat all URL schemes as
  URLs. Example: "['http', 'https', 'mailto']"


Development
===========

You can run the tests by running "tox" in the top-level of the
project.

We are working to expand test coverage, but this will at least test
basic Python 2 and 3 compatability.


Why a bridge?
=============

Many python tools (mostly for documentation creation) rely on
"docutils". But docutils only supports a ReStructuredText syntax.

For instance this issue and this StackOverflow question show that
there is an interest in allowing "docutils" to use markdown as an
alternative syntax.


Why another bridge to docutils?
===============================

recommonmark uses the python implementation of CommonMark while
remarkdown implements a stand-alone parser leveraging parsley.

Both output a "docutils" document tree and provide scripts that
leverage "docutils" for generation of different types of documents.


Acknowledgement
===============

recommonmark is mainly derived from remarkdown by Steve Genoud and
leverages the python CommonMark implementation.

It was originally created by Luca Barbato, and is now maintained in
the Read the Docs (rtfd) GitHub organization.
