On the topic of programming blogs, are there any libraries to automatically detect code snippets within text? I know there are some StackOverflow posts talking about possible approaches to this, but not sure if anyone has actually built an open source solution.

It looks like this highlights code within <pre><code> blocks with a color scheme appropriate for the language, but it can't actually detect whether a snippet is code in the first place.

This is good to know about, although I personally care more about just displaying code blocks in a different typeface than I do about highlighting them appropriately.
