Is there any graphical display tool for diff output?
I would like to post-process diff output and then pass the results to a graphical viewer, such as kdiff3 or xxdiff. If possible, I would like to be able to highlight in-line differences using different colors.
If you can use windows, there is a great program that does this called WinMerge
Here is an example:
Perhaps this is not what you're looking for exactly, but you can do this in using vim:
vimdiff file1 file2 file3
