Snippet List
The default Django urlize filter does not work with html nicely so here I've used an HTML parser [BeautifulSoup](http://www.crummy.com/software/BeautifulSoup/) to quickly search through each text node and run the django urlize filter on it.
Optimizations could be made to include a regex in the soup.findAll() method's text argument to only search those text nodes which matched a url pattern. You could also modify the method to convert the text to urls, such as using your own custom url filter.

Replaces <code> blocks with syntax highlighted code. Use CSS to actually get the colours you want, look at pygments documentation for extracting css for various styles.
This snippet has the advantage of falling back on <pre> if anything goes wrong, and attempting to guess the syntax of code, falling back on python.

A variation on a theme, inspired by [snippet 39][39] and [snippet 119][119]. The
intent is to provide a more generic and simple mechanism for combining
[Markdown][markdown] with [Pygments][pygments]. Common scenarios could include blogging or commenting. Snippet 119 seemed too specific and perhaps not as
efficient, needing to process the HTML twice to accomplish it's ends. The one snag in the implementation is the need to use a tag other than `code` as a wrapper. See the comments for details.
You will need the [BeautifulSoup][soup] module installed.
Sample usage:
from django.db import models
class Blog(models.Model):
'''Bare bones blogging model'''
title = models.CharField(maxlength=255)
slug = models.SlugField(maxlength=255, prepopulate_from=('title',))
pub_date = models.DateTimeField()
# the cooked view, cached for quick retrieval
blog = models.TextField()
# the raw markdown-encoded text, saved for subsequent edits
markdown = models.TextField()
def save(self):
from datetime import datetime
if not self.id and not self.pub_date:
self.pub_date = datetime.now()
self.blog = pygmented_markdown(self.markdown)
super(Blog, self).save()

This is a simple filter I use to display a list of links from a blog entry off in the sidebar ([example](http://www2.jeffcroft.com/blog/2007/feb/25/two-new-django-sites-both-source-available/)).
Requires beautifulsoup. Originally by [Nathan Borror](http://playgroundblues.com), tweaked slightly by me.

This function takes a string (most likely from a template), searches it for `<code>[...]</code>`, highlights it with Pygments, and returns the entire thing back, as a string. (Note: the `<code>[...]</code>` must have a class corresponding to the language inside. If it lacks the class, then it's silently ignored.)
