KDiff
KDiff is a graphical difference viewer for the KDE platform, that allows you to visualize changes to a file.
It is based on and inspired by the Kompare Application and it actually uses a fork of libkomparediff2 for comparing files.
A major difference between Kompare and KDiff is that in KDiff the diff viewer component is based on KDE's KTextEditor allowing for (destination) file editing and providing syntax highlighting.
