At work we use Subversion for just about all our software project data: source code, design documents, reports. Design documents are usually in MS Word, Excel and Visio. TortoiseSVN is great at using MS Word's "track changes" feature to do a graphical diff of two versions of a document.
At home, I use Linux and Subversion, and also store my ODF (OpenOffice.org) documents in Subversion. So I've been interested in getting a graphical diff feature working for these documents too, which can be started from the command line, and ideally integrated with Subversion.
Recently I found a Python script to do this in "OpenOffice / OpenDocument diff" on the Catarsis blog. That in turn was based on the OpenOffice.org diff script used in TortoiseSVN.
I wanted to make some improvements to the script:
- in the original post, the straight quotes are converted to curly quotes by the blog software, which must be reversed to get it running in Python
- filenames weren't being passed as command line parameters
- it didn't work properly on Gnome in Ubuntu, due to some invalid assumptions about whether the just-opened document has the focus in the window manager when it is opened
- it required the user to first manually start OpenOffice.org with the special parameters needed for the scripting to work
So, I've made these improvements. I've got the changes in a Mercurial repository, now hosted on bitbucket.org in the repository: cmcqueen1975/oodiff.
I have been running this on Ubuntu Linux 9.04 (Jaunty). I have not had success running it on Windows.
This script integrates nicely into Mercurial workflow using the extdiff extension. I've got it set up so I can just type hg oodiff file.odt to see how an ODF file within my Mercurial working copy has changed.

I downloaded this but I couldn't get it to work, what's the usage? I'm using standard Jaunty with gnome.
Hello. Ah yes—dependencies. Try installing the package python-uno using Synaptic Package Manager (under System-->Administration menu). If it's still giving you grief, let me know the error message you get, and hopefully I can tell you something useful.
Thanks, works great! Very useful tool.
Thanks, works great! Only feedback is that a different colour rather than the line through in the same colour would be a huge help in usability. But a very useful tool, nice work.
Just automating a built-in feature
Hello. I should clarify—this code doesn't implement the feature, the feature already exists in OpenOffice. This code just automates it so a diff can be started from the command line. If you want to do a diff in OpenOffice.org via the menus, you can do it this way:
Thanks for the tip about open office.
However, does anyone know of a graphical way of comparing power point slides?
