PySVN is a nice graphical client for Subversion. Unfortunately the builtin Diff tools are pretty awkward to use, esp. if the user (like me) is rather well known with Kdiff3.
I figured a bit with the settings and now PySVN diffs gracefully with Kdiff3 for me.
The settings are simple:
Set “External GUI Diff Command”, “Diff Tool” to kdiff3 and the “Tool Arguments” to -L1 %tl -L2 %tr %nl %nr
Happy Diffing!
