From: Jeff King Date: Thu, 18 Aug 2011 05:03:12 +0000 (-0700) Subject: diff: refactor COLOR_DIFF from a flag into an int X-Git-Tag: v1.7.7-rc1~37^2~6 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=f1c9626105d5e4962a5ccaa4620114d03f32ad02;p=git.git diff: refactor COLOR_DIFF from a flag into an int This lets us store more than just a bit flag for whether we want color; we can also store whether we want automatic colors. This can be useful for making the automatic-color decision closer to the point of use. This mostly just involves replacing DIFF_OPT_* calls with manipulations of the flag. The biggest exception is that calls to DIFF_OPT_TST must check for "o->use_color > 0", which lets an "unknown" value (i.e., the default) stay at "no color". In the previous code, a value of "-1" was not propagated at all.
