Using Meld to compare code changes with Git

Install Meld


$ sudo apt-get install meld

Create a script in your home directory.


$ nano ~/diff.py

Paste this in


#!/usr/bin/python

import sys
import os

os.system('meld "%s" "%s"' % (sys.argv[2], sys.argv[5]))

Set script to be executable


$ sudo chmod ug+x ~/diff.py

Run this:


git config --global diff.external ~/diff.py

Now you should be able to run git diff and it should load meld.


$ git diff git_filename_to_diff
