# recommonmark



[![No Maintenance Intended](http://unmaintained.tech/badge.svg)](http://unmaintained.tech/)



**Warning:** recommonmark is now deprecated. We recommend using [MyST](https://github.com/executablebooks/MyST-Parser) for a docutils bridge going forward. See [this issue](https://github.com/readthedocs/recommonmark/issues/221) for background and discussion.



A `docutils`-compatibility bridge to [CommonMark][cm].



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



Documentation is available on Read the Docs: 



Contents

--------



* [API Reference](api_ref.md)

* [AutoStructify Component](auto_structify.md)



## 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:`](http://www.sphinx-doc.org/en/stable/markup/inline.html#role-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.



```python

# 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:



```markdown



# Title



## My Subtitle

```



```markdown



[My Subtitle][]



[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](http://recommonmark.readthedocs.org/en/latest/auto_structify.html)

for more information about configuration and usage.



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



```python

# 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](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][dc] only supports a ReStructuredText syntax.



For instance [this issue][sphinx-issue] and [this StackOverflow

question][so-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][pcm] of [CommonMark][cm] while

[remarkdown][rmd] implements a stand-alone parser leveraging [parsley][prs].



Both output a [`docutils` document tree][dc] and provide scripts

that leverage `docutils` for generation of different types of documents.



## Acknowledgement



recommonmark is mainly derived from [remarkdown][rmd] by Steve Genoud and

leverages the python CommonMark implementation.



It was originally created by [Luca Barbato][lu-zero],

and is now maintained in the Read the Docs (rtfd) GitHub organization.
