Sphinx 文档和指向 Markdown 的链接

Question

我正在尝试使用 Sphinx 从 Markdown 源构建一些文档。我的conf.py如下...

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

生成了文档构建和html输出，但是README.md在两个子目录中有指向其他markdown文档的链接，例如以下...

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

...在已翻译的README.html 文档中，目标尚未转换为已翻译的HTML 目标，因为它被识别为reference external...

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

...我有一半的期望/希望它会输出为reference internal 并适当地转换文件扩展名...

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

...这样链接的工作方式与侧边栏中的目录相同。

任何关于这是否可以实现的建议将不胜感激。

干杯。

尝试@waylan 建议的解决方案我已将以下内容添加到conf.py 到enable_auto_doc_ref...

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

...在运行make html 时出现以下错误.....

TypeError: 'NoneType' object is not callable

我查看了最后两个电话，我认为这可能归结为 content 未设置，这可能与我的 index.rst 有关，但我在这里真的超出了我的深度。

recommonmark documentation 建议通过将以下内容添加到您的 config.py 文件来启用 AutoStructify：

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)

这将为您提供以下功能：

• enable_auto_toc_tree：是否开启Auto Toc Tree功能。
• auto_toc_tree_section：启用后，自动目录树只会在与标题匹配的部分上启用。
• enable_auto_doc_ref：是否开启Auto Doc Ref功能。
• enable_math：是否启用数学公式
• enable_inline_math：是否启用内联数学
• enable_eval_rst：是否启用 Embed reStructuredText。
• url_resolver：将文档中现有的相对位置映射到 http 链接的函数

值得注意的是Auto Doc Ref 功能：

在一个文档中引用另一个文档页面是很常见的。我们 通常使用参考来做到这一点。 AutoStructify 将翻译这些 参考块转化为结构化文档参考。例如

[API Reference](api_ref.md)

将被翻译成以下 reStructuredText 代码的 AST

:doc:`API Reference </api_ref>`

它会被渲染为 API 参考

为什么这是必要的？因为，与 Rst 不同，Markdown 不了解给定文档之外的任何内容，也不支持 Rst 样式指令。因此，没有转换 URL 的机制。

相反，AutoStructify 会等到 recommonmark 桥将 Markdown 转换为 Sphinx 的底层文档结构（docutils 文档对象）之后，然后在其上运行一系列转换器以提供有限的类似 Rst 的功能。即使使用 AutoStructify，在使用 Markdown 时您也永远不会获得完整的功能支持。这需要 Markdown 原生支持指令，这不太可能发生。
