kapyshin / paka.cmark

Lightweight CFFI-based Python bindings to cmark library (CommonMark implementation in C).

paka.cmark

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 3.6 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_UNSAFE, 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)
• safe HTML output is on by default (like in libcmark)

Examples

>>> from paka import cmark

Render with CMARK_OPT_DEFAULT | CMARK_OPT_NOBREAKS:

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

Render with CMARK_OPT_DEFAULT | CMARK_OPT_NOBREAKS | CMARK_OPT_UNSAFE:

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

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*
