Sphinx文档和Markdown链接

Question

I'm trying to use Sphinx to build some documentation from Markdown source. My conf.py is as follows...

conf.py

from recommonmark.parser import CommonMarkParser
project = 'DS'
copyright = '2018, DS'
author = 'DS, Work'

version = ''
release = ''

extensions = []

templates_path = ['_templates']

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

master_doc = 'index'

language = None
exclude_patterns = []
pygments_style = 'sphinx'
html_theme = 'classic'
html_static_path = ['_static']
source_parsers = {
   '.md': CommonMarkParser,
}
htmlhelp_basename = 'DSDocumentationdoc'
latex_elements = {
}
latex_documents = [
    (master_doc, 'DSDocumentation.tex', 'DS Documentation',
     'DS, Work', 'manual'),
]
man_pages = [
    (master_doc, 'dsdocumentation', 'DS Documentation',
     [author], 1)
]
texinfo_documents = [
    (master_doc, 'DSDocumentation', 'DS Documentation',
     author, 'DSDocumentation', 'One line description ofproject.',
 'Miscellaneous'),
]

index.rst

Welcome to DS Documentation!
======================================

The following documentation is produced and maintained by the Data Science team.

Contents:

.. toctree::
   :maxdepth: 2
   :glob:

   README.md
   documentation.md
   getting_started/*
   how-tos/*
   statistics_data_visualisation.md

The documents build and html output is generated, however README.md has links to other markdown documents in the two sub-directories such as the following...

... [this document](./getting_started/setting_your_machine_up.md)...

...which in the translated README.html document the target has not been converted to the translated HTML target as its been recognised as reference external ...

...<a class="reference external" href="./getting_started/setting_your_machine_up.md">this document</a>...

...I was half-expecting/hoping it would output as reference internal and convert the file extension approrpiately...

...<a class="reference internal" href="./getting_started/setting_your_machine_up.html">this document</a>...

...so that links worked in the same vein as the Table of Contents does in the sidebar.

Any suggestions as to whether this can be achieved would be appreciated.

Cheers.

EDIT

Trying out the solution suggested by @waylan I have added the following to by conf.py to enable_auto_doc_ref ...

def setup(app):
    app.add_config_value('recommonmark_config', {
        'enable_auto_doc_ref': True,
    }, True)
    app.add_transform(AutoStructify)

...and on running make html I get the following error.....

    content=content)
TypeError: 'NoneType' object is not callable

I've looked through the last two calls and I think this might be down to content not being set, which may be something to do with my index.rst but I'm really out of my depth here.

Answer 1

The recommonmark documentation suggests enabling AutoStructify by adding the following to your config.py file:

from recommonmark.transform import AutoStructify

github_doc_root = 'https://github.com/rtfd/recommonmark/tree/master/doc/'
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)

This will give you the following features:

• enable_auto_toc_tree : whether enable Auto Toc Tree feature.
• auto_toc_tree_section : when enabled, Auto Toc Tree will only be enabled on section that matches the title.
• enable_auto_doc_ref : whether enable Auto Doc Ref feature.
• enable_math : whether enable Math Formula
• enable_inline_math : whether enable Inline Math
• enable_eval_rst : whether Embed reStructuredText is enabled.
• url_resolver : a function that maps a existing relative position in the document to a http link

Of note is the Auto Doc Ref feature:

It is common to refer to another document page in one document. We usually use reference to do that. AutoStructify will translate these reference block into a structured document reference. For example

 [API Reference](api_ref.md) 

will be translated to the AST of following reStructuredText code

 :doc:`API Reference </api_ref>` 

And it will be rendered as API Reference

Why is this necessary? Because, unlike Rst, Markdown does not have any knowledge of anything outside of the given document and has no support for Rst style directives. Therefore, there is no mechanism to transform a URL.

Instead, AutoStructify waits until after the recommonmark bridge converts the Markdown to Sphinx's underlying document structure (docutils document object), then it runs a series of transformers on it to provide limited Rst like functionality. Even with AutoStructify, you will never get full feature support when using Markdown. That would require Markdown to have native support for directives, which is not likely to ever happen.
