I had to do this again today because of my hard drive crash, so I’ll document it here in case I have to do it again in the future.

Due to the relatively poor integration of GUI tools for Subversion (I consider them a leaky abstraction) with the command line version, I only use the command line for most of the actions. Still, I can’t stand the diff output generated by subversion.

It’s not hard to plug in a different diff tool like SourceGear’s Vault Diff and Merge into subversion. Here are the steps:

• create a batch file called diff.cmd and put it somewhere in your path; the contents of this file should be a single line: <path_to_vault_directory>\sgdm.exe %6 %7
• go to %AppData%\Subversion folder and open config file (it has no extension) in notepad (or suitable replacement); then search for diff-cmd = … and replace right hand side with diff.cmd
• enjoy!
