将Sphinx与Markdown而不是RST一起使用

I hate RST but love sphinx. Is there a way that sphinx reads markdown instead of reStructuredText?

The “proper” way to do that would be to write a docutils parser for markdown. (Plus a Sphinx option to choose the parser.) The beauty of this would be instant support for all docutils output formats (but you might not care about that, as similar markdown tools already exist for most). Ways to approach that without developing a parser from scratch:

1. You could cheat and write a “parser” that uses Pandoc to convert markdown to RST and pass that to the RST parser :-).

2. You can use an existing markdown->XML parser and transform the result (using XSLT?) to the docutils schema.

3. You could take some existing python markdown parser that lets you define a custom renderer and make it build docutils node tree.

4. You could fork the existing RST reader, ripping out everything irrelevant to markdown and changing the different syntaxes (this comparison might help)…
   EDIT: I don’t recommend this route unless you’re prepared to heavily test it. Markdown already has too many subtly different dialects and this will likely result in yet-another-one…

UPDATE: https://github.com/sgenoud/remarkdown is a markdown reader for docutils. It didn’t take any of the above shortcuts but uses a Parsley PEG grammar inspired by peg-markdown.

• Doesn’t yet support directives.

UPDATE: https://github.com/readthedocs/recommonmark and is another docutils reader, natively supported on ReadTheDocs. Derived from remarkdown but uses the CommonMark-py parser.

• It can convert specific more-or-less natural Markdown syntaxes to appropriate structures e.g. list of links to a toctree. * Doesn’t have generic native syntax for roles.
• Supports embedding any rST content, including directives, with an as well as a shorthand for directives DIRECTIVE_NAME:: ....

UPDATE: MyST is yet another docutins/Sphinx reader. Based on markdown-it-py, CommonMark compatible.

• Has a generic {ROLE_NAME}`...` syntax for roles.
• Has a generic syntax for directives with ```{DIRECTIVE_NAME} ... fenced blocks.

In all cases, you’ll need to invent extensions of Markdown to represent Sphinx directives and roles. While you may not need all of them, some like .. toctree:: are essential.
This I think is the hardest part. reStructuredText before the Sphinx extensions was already richer than markdown. Even heavily extended markdown, such as pandoc’s, is mostly a subset of rST feature set. That’s a lot of ground to cover!

Implementation-wise, the easiest thing is adding a generic construct to express any docutils role/directive. The obvious candidates for syntax inspiration are:

• Attribute syntax, which pandoc and some other implementations already allow on many inline and block constructs. For example `foo`{.method} -> `foo`:method:.
• HTML/XML. From <span class="method">foo</span> to the kludgiest approach of just inserting docutils internal XML!
• Some kind of YAML for directives?

But such a generic mapping will not be the most markdown-ish solution… Currently most active places to discuss markdown extensions are https://groups.google.com/forum/#!topic/pandoc-discuss, https://github.com/scholmd/scholmd/

This also means you can’t just reuse a markdown parser without extending it somehow. Pandoc again lives up to its reputation as the swiss army knife of document conversion by supporting custom filtes. (In fact, if I were to approach this I’d try to build a generic bridge between docutils readers/transformers/writers and pandoc readers/filters/writers. It’s more than you need but the payoff would be much wider than just sphinx/markdown.)

Alternative crazy idea: instead of extending markdown to handle Sphinx, extend reStructuredText to support (mostly) a superset of markdown! The beauty is you’ll be able to use any Sphinx features as-is, yet be able to write most content in markdown.

There is already considerable syntax overlap; most notably link syntax is incompatible. I think if you add support to RST for markdown links, and ###-style headers, and change default `backticks` role to literal, and maybe change indented blocks to mean literal (RST supports > ... for quotations nowdays), you’ll get something usable that supports most markdown.

You can use Markdown and reStructuredText in the same Sphinx project. How to do this is succinctly documented on Read The Docs.

Install recommonmark (pip install recommonmark) and then edit conf.py:

from recommonmark.parser import CommonMarkParser

source_parsers = {
    '.md': CommonMarkParser,
}

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

I’ve created a small example project on Github (serra/sphinx-with-markdown) demonstrating how (and that) it works. It uses CommonMark 0.5.4 and recommonmark 0.4.0.

This doesn’t use Sphinx, but MkDocs will build your documentation using Markdown. I also hate rst, and have really enjoyed MkDocs so far.

Update: this is now officially supported and documented in the sphinx docs.

It looks like a basic implementation has made it’s way into Sphinx but word has not gotten round yet. See github issue comment

install dependencies:

pip install commonmark recommonmark

adjust conf.py:

source_parsers = {
    '.md': 'recommonmark.parser.CommonMarkParser',
}
source_suffix = ['.rst', '.md']

Markdown and ReST do different things.

RST provides an object model for working with documents.

Markdown provides a way to engrave bits of text.

It seems reasonable to want to reference your bits of Markdown content from your sphinx project, using RST to stub out the overall information architecture and flow of a larger document. Let markdown do what it does, which is allow writers to focus on writing text.

Is there a way to reference a markdown domain, just to engrave the content as-is? RST/sphinx seems to have taken care of features like toctree without duplicating them in markdown.

This is now officially supported: http://www.sphinx-doc.org/en/stable/markdown.html

I went with Beni’s suggestion of using pandoc for this task. Once installed the following script will convert all markdown files in the source directory to rst files, so that you can just write all your documentation in markdown. Hope this is useful for others.

#!/usr/bin/env python
import os
import subprocess

DOCUMENTATION_SOURCE_DIR = 'documentation/source/'
SOURCE_EXTENSION = '.md'
OUTPUT_EXTENSION = '.rst'

for _, __, filenames in os.walk(DOCUMENTATION_SOURCE_DIR):
    for filename in filenames:
        if filename.endswith('.md'):
            filename_stem = filename.split('.')[0]
            source_file = DOCUMENTATION_SOURCE_DIR + filename_stem + SOURCE_EXTENSION
            output_file = DOCUMENTATION_SOURCE_DIR + filename_stem + OUTPUT_EXTENSION
            command = 'pandoc -s {0} -o {1}'.format(source_file, output_file)
            print(command)
            subprocess.call(command.split(' '))

There is a workaround.
The sphinx-quickstart.py script generates a Makefile.
You can easily invoke Pandoc from the Makefile every time you’d like to generate the documentation in order to convert Markdown to reStructuredText.

Here’s a new option. MyST adds some features to Markdown that allow Sphinx to build docs like rst does. https://myst-parser.readthedocs.io/en/latest/

Note that building documentation using maven and embedded Sphinx + MarkDown support is fully supported by following maven plugin :
