[Trac] description diff without rebuilding the exe

2014-05-01 Thread David Vanleeuwen 
I am running trac 0.12 on a server (our company actually has several trac 
systems using different versions) and I want to be able to diff the 
description in email notifications instead of Old and then New 
descriptions.  I have seen some solutions for this by changing the 
notification.py and rebuilding the exe.  Does anyone know of a way to do 
this without changing the source code and then rebuilding the exe?

I was thinking that I could possibly do some python in the 
ticket_notify_email.txt to pull apart $changes_descr into old description 
and then new discription and then run a diff.  Is there a better way to do 
this? Also, is there a way to run a python script in genshi?

Thanks,
David

I do know at least of two:

Python code block/lines (as permitted by Genshi xmlns as I guess)

Beware, that cited examples are not showing ideal code by no means, just
meant for illustration of the real-world use case.
