If anyone got recommendations for nice sub-line diff visualizers (i.e. producing some nice HTML to display the differences) let me know.
Including commercial stuff?
i.e: are you looking for code, or just inspiration?
If it's the latter, I'd suggest you to take a look at Araxis Merge. It is a damn nice (and damn expensive :) tool.
I highly recommend Beyond Compare. No Mac version, unfortunately, but it's good enough for me to keep a Windows install in Parallels primarily to run it. And at $30/seat, I wouldn't even call it damn expensive. (Though if you count the cost of Parallels and a Windows license, then I suppose it qualifies. :-)
No, he (Allan) is talking about some open-source thing we can drop into TextMate diff/version control bundles.
