From 8f85599aba6b569de5c559994704a416f52bc031 Mon Sep 17 00:00:00 2001 From: Pat Thoyts Date: Fri, 22 Oct 2010 16:14:38 +0100 Subject: [PATCH] git-gui: apply color information from git diff output This patch extracts the ANSI color sequences from git diff output and applies these to the diff view window. This ensures that the gui view makes use of the current git configuration for whitespace display. ANSI codes may include attributes, foreground and background in a single sequence. Handle this and support bold and reverse attributes. Ignore all other attributes.
