:mod:`gfm.strikethrough` -- Strike-through support

The :mod:`gfm.strikethrough` module provides GitHub-like syntax for
strike-through text, that is text between double tildes:
``some ~~strike-through'ed~~ text``

Typical usage

.. testcode::

   import markdown
   from gfm import StrikethroughExtension

   print(markdown.markdown("I ~~like~~ love you!",

.. testoutput::

   <p>I <del>like</del> love you!</p>


from __future__ import unicode_literals

import markdown

STRIKE_RE = r'(~{2})(.+?)(~{2})'  # ~~strike~~

[docs]class StrikethroughExtension(markdown.Extension): """ An extension that adds support for strike-through text between two ``~~``. """ def extendMarkdown(self, md, md_globals): pattern = markdown.inlinepatterns.SimpleTagPattern(STRIKE_RE, 'del') md.inlinePatterns.add('gfm-strikethrough', pattern, '_end')
