Git diff with Meld in Ubuntu

Are you using Git in Ubuntu and want to use a visual diff viewer? Excellent. May i suggest the awesome meld. Meld is  a visual diff and merge tool targeted at developers. Meld can diff files, directories, and version controlled projects. If you don't already have Meld, then install it:

sudo apt-get install meld

Next enter enter this into a terminal:

git config --global diff.external meld

Then navigate to a Git tracked directory and enter this (with an actual filename):

git diff filename

Meld will open but it will complain about bad parameters. The problem is that Git sends the external diff viewer seven parameters but Meld only needs two of them - which are the  filenames of files to compare. One way to fix it is to write a script to format the parameters before sending them to Meld.

Create a new python script in your home directory (or wherever, it doesn't matter) and call it


import sys
import os

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

Now we can set Git to perform it's diff on our new script (replacing the path with yours):

git config --global diff.external /home/teroz/

git diff filename

This time when we do a diff it will launch Meld with the right parameters and we will see our visual diff - Enjoy

Hey all am working on a 100% ruby implementation of SIP ( This is because, firstly, there doesn't seem to by any freely availabe ( yes i looked - not just another excuse to implement my very own version ) and i get to learn ruby for free. Btw - if anyone knows of any such libaray , freely availabe, let me know.
While we are on the subject of open source why the hell are there one million versions of every little thing. I guess the one of the joys of open source is the every one can go out in there own direction but damn :(
