假设我在同一文件夹中有两个文件a.rst
和b.rst
,a.rst
看起来像这样
.. _foo: http://stackoverflow.com
`foo`_ is a website
似乎在foo
中使用b.rst
是不允许的。有没有办法定义超链接并在多个文件中使用它们?
跟进
史蒂夫·皮尔西建议我使用extlinks
扩展。它的实现和docstring可以看到here on github。
就我而言,我在conf.py中定义了维基百科链接
extlinks = {'wiki': ('https://en.wikipedia.org/wiki/%s', '')}
在.rst
文件中,使用它们
:wiki:`Einstein <Albert_Einstein>`
爱因斯坦将作为https://en.wikipedia.org/wiki/Albert_Einstein的链接显示
至少有四种可能的解决方案。
将完整的reST放在每个文件中。你可能不希望这样。
这个很聪明。在rst_epilog
中配置conf.py
值以及substition with the replace
directive:
rst_epilog = """
.. |foo| replace:: foo
.. _foo: http://stackoverflow.com
"""
和休息:
|foo|_ is a website
收益率:
<a class="reference external" href="http://stackoverflow.com">foo</a>
对于您希望拥有基本URL并附加路径段或参数的外部网站的链接,您可以在extlinks
中使用conf.py
:
extensions = [
...
'sphinx.ext.extlinks',
...
]
...
extlinks = {'so': ('https://stackoverflow.com/%s', None)}
然后在你的reST:
:so:`questions/49016433`
产量:
<a class="reference external"
href="https://stackoverflow.com/questions/49016433">
https://stackoverflow.com/questions/49016433
</a>
对于由Sphinx生成的文档的外部网站,您可以在intersphinx
中使用conf.py
:
extensions = [
...
'sphinx.ext.intersphinx',
...
]
...
intersphinx_mapping = {
'python': ('https://docs.python.org/3', None),
}
然后在你的reST:
:py:mod:`doctest`
产量:
<a class="reference external"
href="https://docs.python.org/3/library/doctest.html#module-doctest"
title="(in Python v3.6)">
<code class="xref py py-mod docutils literal">
<span class="pre">doctest</span>
</code>
</a>
这是另一种解决方案:对于官方支持的共享外部链接的方式来说,它有点hacky并且有点不同。
首先完成安装然后:
conf.py
中添加commonlinks
条目在extensions
conf.py
中配置常用链接的地图:例如:
extensions = [
...,
'sphinx.ext.commonlinks'
]
commonlinks = {
'issues': 'https://github.com/sphinx-doc/sphinx/issues',
'github': 'https://github.com'
}
然后在.rst文件中你可以这样做:
The :github:`_url_` url is aliased to :github:`GitHub` and also to :github:`this`
所需要的只是将文件sphinx/ext
复制到commonlinks.py
目录中:
# -*- coding: utf-8 -*-
"""
sphinx.ext.commonlinks
~~~~~~~~~~~~~~~~~~~~~~
Extension to save typing and prevent hard-coding of common URLs in the reST
files.
This adds a new config value called ``commonlinks`` that is created like this::
commonlinks = {'exmpl': 'http://example.com/mypage.html', ...}
Now you can use e.g. :exmpl:`foo` in your documents. This will create a
link to ``http://example.com/mypage.html``. The link caption depends on the
role content:
- If it is ``_url_``, the caption will be the full URL.
- If it is a string, the caption will be the role content.

要找到sphinx
安装目录,一种方法是:
$ python 3
> import sphinx
> sphinx
<module 'sphinx' from '/usr/local/lib/python3.5/dist-packages/sphinx/__init__.py'>
然后:
% cp commonlinks.py /usr/local/lib/python3.5/dist-packages/sphinx/ext
