paka.cmark

https://travis-ci.org/PavloKapyshin/paka.cmark.svg?branch=master

paka.cmark is a Python library that wraps subset of cmark C library (that is one of reference implementations of CommonMark).

Features

  • Python 2.7 and 3.5 are supported
  • PyPy (Python 2.7) is supported, as wrapping is made with CFFI
  • no need to install libcmark, it is bundled with paka.cmark (and sources of the former are regularly updated according to upstream)
  • supported output: HTML, XML, CommonMark, man, LaTeX
  • supported options: CMARK_OPT_SAFE, CMARK_OPT_NOBREAKS, CMARK_OPT_HARDBREAKS, CMARK_OPT_SOURCEPOS, CMARK_OPT_SMART
  • unlike libcmark—underlying C library—paka.cmark uses CMARK_OPT_NOBREAKS by default (breaks argument allows to control line break rendering)

Examples

>>> from paka import cmark

Render with CMARK_OPT_DEFAULT | CMARK_OPT_NOBREAKS:

>>> print(cmark.to_html(u"Hello,\n*World*!"))
<p>Hello, <em>World</em>!</p>

Render with CMARK_OPT_DEFAULT | CMARK_OPT_NOBREAKS | CMARK_OPT_SAFE:

>>> print(cmark.to_html(u"<p>nope</p>", safe=True))
<!-- raw HTML omitted -->

Render with CMARK_OPT_DEFAULT:

>>> print(cmark.to_html(u"Hello,\n*World*!", breaks=True))
<p>Hello,
<em>World</em>!</p>

Render with CMARK_OPT_DEFAULT | CMARK_OPT_HARDBREAKS:

>>> print(cmark.to_html(u"Hello,\n*World*!", breaks="hard"))
<p>Hello,<br />
<em>World</em>!</p>

Render CommonMark with CMARK_OPT_DEFAULT | CMARK_OPT_NOBREAKS:

>>> print(cmark.to_commonmark(u"_Hello_"))
*Hello*
