Environment Variable for defining differencing tool in Subversion

Question

I see that there is the SVN_EDITOR environment variable to define what editor to use with subversion, and there's also SVN_MERGE environment variable for merging files.

Is there an environment variable for defining the differencing tool?

Answer 1

You can customize the difference tool used by setting diff-cmd in your ~/.subversion/config file; see the manual. You can also use a --diff-cmd option on the command-line.

Answer 2

You could also add an alias such as the following to the same default profile: alias svndiff='svn diff --diff-cmd /usr/bin/meld'
