pygmentize -f rtf FILE | pbcopy(Pasting RTF directly into PowerPoint doesn't work correctly, at least with PowerPoint 2008 — it extends colour spans longer than it should, and sometimes removes line breaks. Going via TextEdit seems to solve the problem.)
Great tip! Seemingly obvious in hindsight, yet something I had not considered at all before.
For future readers, note that you can also read from the clipboard if you don't want to extract your snippets out to files: pbpaste | pygmentize -l ruby -f rtf | pbcopy. In this scenario the lexer (-l) should be specified, since there will be no filename to guess from.
WHOW... this definitely makes my day. Need to prepare dozens of slides with (cucumber) code - your tipp saved hours! Thanx.
It really helps me a lot!
and for current PPT you could skip step 2
With PowerPoint 2011 for Mac, I found that it is not necessary to go via TextEdit to preserve the formatting -- however it was necessary to use the "Paste Options" popup to "Keep Source Formatting" (explained there for Windows).
I found a page with previews of all the pygmentize styles which can be helpful finding a style for you (especially in my case, as I needed one with white text, whereas the default one has black text).
Thanks for this great tip, BTW. Also I didn't know about pbcopy!
