降价命名链接的第一个等价物是什么？

Question

在markdown中，我可以这样做：

Imagine a long paragraph here, with [an extended phrase linked
to something elsewhere][shortref].

[shortref]: http://really-long-and-annoying-link-here

reStructuredText 中的等效语法是什么？

Answer 1

您可以定义一个substitution，其中包含一个替换和对相应超链接目标的引用。

Imagine a long paragraph here, with |SR|_.

.. |SR| replace:: an extended phrase linked to something elsewhere
.. _SR: http://really-long-and-annoying-link-here

另一个选项不是完全等价的，但仍然接近：

Imagine a long paragraph here, with `an extended phrase linked
to something elsewhere`_.

Here is a short reference link: `shortref`_.

.. _shortref: `an extended phrase linked to something elsewhere`_
.. _an extended phrase linked to something elsewhere: http://really-long-and-annoying-link-here

上面的例子使用了external and indirect hyperlink targets的组合。
