The Pygments Markdown Preprocessor
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This fragment is a Markdown_ preprocessor that renders source code
to HTML via Pygments. To use it, invoke Markdown like so::
from markdown import Markdown
md = Markdown()
md.textPreprocessors.insert(0, CodeBlockPreprocessor())
html = md.convert(someText)
markdown is then a callable that can be passed to the context of
a template and used in that template, for example.
This uses CSS classes by default, so use
``pygmentize -S <some style> -f html > pygments.css``
to create a stylesheet to be added to the website.
You can then highlight source code in your markdown markup::
[sourcecode:lexer]
some code
[/sourcecode]
