I found pygments [1] as exactly the tool I was looking for. They don't support so much languages as we have in our repository, and of course the css styles that come with it, are not way as stunningly beautiful as the TextMate styles ;-) but it's quiet alright and its API is easy to use and well documented. I found Pygments through paste.e-scribe [2] ... I just wished I could use pastie's [3] codestyler's [4] colors and lexers ... mmm dreaming ...
