If you use Mercurial, Git or Subversion at the shell, CDiff is a useful tool to have around. By default,
hg diff or
git diff is displayed in the classic diff format. This shows the before-and-after changed lines one below the other. Personally, I find this very confusing. I very much prefer the side-by-side diff view used in GUI diff programs. cdiff is a great way to get this side-by-side diff view at the shell in full color!
CDiff is a Python program that can be installed from PyPI using this command:
$ sudo pip install cdiff
Note: Do not confuse this package with the colordiff package that is available in Ubuntu repositories. That is something else!
cdiff in any subdirectory of a Mercurial, Git or Subversion repository. By default, this shows a colorful diff of the changes in all uncommitted files.
To get side-by-side diff view use:
CDiff assumes that your window width is 80 by default. I prefer to view side-by-side diff that uses the full width of my terminal window. This can be achieved by invoking:
cdiff -s -w 0
To diff two files, just pass them through
diff -u and pipe that to cdiff:
$ diff -u file1.cpp file2.cpp | cdiff -s
Tried with: CDiff 0.9.7, Python 2.7.6 and Ubuntu 14.04
