Anybody know of a better open source diff than diff? Possibly in one of the open source SCM systems like darcs, mercurial, or arch/tla?


I use the free version of Perforce. It supports two users and 5 workspaces. The Merge utility is very nice. I recently used it to back-rev a Java application that I broke. I was trying to add a file cache feature and speed the application up, but I introduced a bug. I compared the previous version with the new version using the Perforce Merge and diff tools to a) find and remove the offending code, b) make the current (broken) version work the same way as the previous (working) version without having to completely debug the current version, and c) make sure all the new code that did work was left intact in the merged result.


(Damn, I thought I sent this several hours ago!)
