Thu May 17 16:20:04 2001 Jonathan Blandford <jrb@redhat.com> * demos/gtk-demo/main.c (fontify): It's the worlds ugliest highlighting code!!!! The result is okay so long as you don't try to stress it. It also highlights a bug in the TextView so it's in an unproportional font right now until it's fixed. *demos/gtk-demo/*.c: Clean up code a bit to make it ugly-parser(TM) friendly. (-:
