I'm using processwire to power my (mostly) coding blog, and have had problem finding a stable solution for including code snippets from various langauges, to display them with proper formatting and syntax highlighting etc. I finally ended up just embedding gists (gist.github.com) since it was the only thing that would not mess up totally with the HTML on the page, etc, but that is some extra work, creating a new gist for every little code snippet you want to show.
So, I was wondering what other use for this purpose, and what seems to be the best solution right now?
