I wanted to use Markdown for posting on Blogger. As I am planning to post source code examples I wanted to be able to do syntax highlighting of the code.
I've found python-markdown which is Markdown implementation in Python. Furthermore, some searching returned Pygments as an option to generate html syntax highlighting from plain source code snippets and I was considering to use Beautiful Soup to extract relevant code blocks from processed Markdown output and replace them with syntax formatted html. There is a python-markdown extension CodeHilite which adds code syntax highlighting support to Python-Markdown using Pygments.
