Anybody have any suggestions for DIFF?

I searched through the various archives, and also tried nearly all the
gems related to diff (I dont think some of them are Ruby 2.x compatible
although they dont mention that). Anyhow, I have a script that compares
two sets of files, finds the matching file (the file names dont match,
so Im forced to look at the XML and compare a field via
nokogiri). Once found, all I really want to do is do something like the
unix diff between the two files. I realize I can use %x(diff file1
file2), but thats not going to work with my windows coworkers. Most of
the diff gems Ive found either make a mess of the output, or are so
woefully documented that I couldnt get the diff to really find the
differences between the two files.

Anybody have any luck with any of the gems out there? If so, any hints
on getting output that remotely looks like the diff output?

Thanks,
Wayne

There seem to be some XML diff tools out there but I am not aware of any
gem.

Kind regards

diff-lcs requires a bit of digging into the API but it works well. It’s
even got a command line diff clone built in called “ldiff” – check out
its source code in ldiff.rb (you can find it after install by using “gem
which ldiff”)

As usual, thanks Robert! Ill give that a look.
