Version: 3.4 (using KDE 3.5.0-4.0.fc3.kde, Fedora Core release 3 (Heidelberg)) Compiler: gcc version 3.4.4 20050721 (Red Hat 3.4.4-2) OS: Linux (i686) release 2.6.12-1.1381_FC3 I think kompare should also parse stdin for diff output. Then svn diff somefile.tex | kompare would be possible.
try "svn diff somefile.tex | kompare -" kompare with one argument assumes that the argument is a file containing a diff. a hyphen in place of a filename interpreted to mean stdin in kompare and many other programs
