I google'd this multiple times in the past but I've never found an answer. Is there a way to save vimdiff's output (preferably while maintaining colors, highlights, etc.)? I'd like to send this one output file to other people and tell them "just open this file, here are the differences, side by side and highlighted".
If there are better alternatives to vimdiff for this purpose, I'm open to suggestions - something that would work on both Windows and Linux platforms is ideal.
Vim can export to HTML, see:
