----

M2RR (R for Reborn) converts a markdown file including reStructuredText (rst) markups to a valid
rst format.

Why another converter?
----------------------

I wanted to write sphinx document in markdown, since it's widely used now and
easy to write code blocks and lists. However, converters using pandoc or
recommonmark do not support many rst markups and sphinx extensions. For
example, rst's reference link like ``see `ref`_`` (this is very convenient in
long document in which same link appears multiple times) will be converted to
a code block in HTML like ``see <code>ref</code>_``\ , which is not expected.

Why fork
--------

The original author seems to be no longer maintain the repository actively.
`Original Repo <https://github.com/miyakogi/m2r/>`_.

Features
--------


* Basic markdown and some extensions (see below)

  * inline/block-level raw html
  * fenced-code block
  * tables
  * footnotes (\ ``[^1]``\ )

* Inline- and Block-level rst markups

  * single- and multi-line directives (\ ``.. directive::``\ )
  * inline-roles (\ ``:code:`print(1)` ...``\ )
  * ref-link (\ ``see `ref`_``\ )
  * footnotes (\ ``[#fn]_``\ )
  * math extension inspired by `recommonmark <https://recommonmark.readthedocs.io/en/latest/index.html>`_

* Sphinx extension

  * add markdown support for sphinx
  * ``mdinclude`` directive to include markdown from md or rst files
  * option to parse relative links into ref and doc directives (\ ``m2rr_parse_relative_links``\ )

* Pure python implementation

  * pandoc is not required

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

Python 2.7 or Python 3.4+ is required.

.. code-block:: text

   pip install m2rr

Or,

.. code-block:: text

   python3 -m pip install m2rr

Usage
-----

Command Line
^^^^^^^^^^^^

``m2rr`` command converts markdown file to rst format.

.. code-block:: text

   m2rr your_document.md [your_document2.md ...]

Then you will find ``your_document.rst`` in the same directory.

Programmatic Use
^^^^^^^^^^^^^^^^

Import ``m2rr.convert`` function and call it with markdown text.
Then it will return converted text.

.. code-block:: python

   from m2rr import convert
   rst = convert('# Title\n\nSentence.')
   print(rst)
   # Title
   # =====
   #
   # Sentence.

Or, use ``parse_from_file`` function to load markdown file and obtain converted
text.

.. code-block:: python

   from m2rr import parse_from_file
   output = parse_from_file('markdown_file.md')

This is an example of setup.py to write README in markdown, and publish it to
PyPI as rst format.

.. code-block:: python

   readme_file = os.path.join(os.path.dirname(os.path.abspath(__file__)), 'README.md')
   try:
       from m2rr import parse_from_file
       readme = parse_from_file(readme_file)
   except ImportError:
       # m2rr may not be installed in user environment
       with open(readme_file) as f:
           readme = f.read()
   setup(
       ...,
       long_description=readme,
       ...,
   )

Sphinx Integration
^^^^^^^^^^^^^^^^^^

In your conf.py, add the following lines.

.. code-block:: python

   extensions = [
       ...,
       'm2rr',
   ]

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

Write index.md and run ``make html``.

When ``m2rr`` extension is enabled on sphinx and ``.md`` file is loaded, m2rr
converts to rst and pass to sphinx, not making new ``.rst`` file.

mdinclude directive
~~~~~~~~~~~~~~~~~~~

Like ``.. include:: file`` directive, ``.. mdinclude:: file`` directive inserts
markdown file at the line.

Note: do not use ``.. include:: file`` directive to include markdown file even if
in the markdown file, please use ``.. mdinclude:: file`` instead.

Restrictions
------------


* In the rst's directives, markdown is not available. Please write in rst.
* Column alignment of tables is not supported. (rst does not support this feature)
* Heading with overline-and-underline is not supported.

  * Heading with underline is OK

* Rst heading marks are currently hard-coded and unchangeable.

  * H1: ``=``\ , H2: ``-``\ , H3: ``^``\ , H4: ``~``\ , H5: ``"``\ , H6: ``#``

Example
-------

See `example document <https://qhua948.github.io/m2rr/example.html>`_ and `its
source code <https://github.com/qhua948/m2rr/blob/master/docs/example.md>`_.

I'm using m2rr for writing user guide of `WDOM <https://github.com/miyakogi/wdom>`_.
So you can see it as another example. Its `HTML is
here <http://wdom-py.readthedocs.io/en/latest/guide/index.html>`_\ , and `its
source code is here <https://github.com/miyakogi/wdom/tree/dev/docs/guide>`_.

Demo editor
^^^^^^^^^^^

Demo editor of m2rr is available.

Acknowledgement
---------------

m2rr is written as an extension of
`mistune <http://mistune.readthedocs.io/en/latest/>`_\ , which is highly extensible
pure-python markdown parser.
Without the mistune, I couldn't write this. Thank you!
