Subject: [PATCH v3 00/11] Fix color handling in git add -i
Date: Mon, 16 Nov 2020 16:08:21 +0000	[thread overview]
Message-ID: <pull.785.v3.git.1605542912.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.785.v2.git.1605097704.gitgitgadget@gmail.com>

This patch series started out as a tiny fix for a bug reported by Philippe
Blain in 
https://lore.kernel.org/git/313B8999-1E99-4695-A20D-E48840C30879@gmail.com/.
And then I only wanted to add a regression test to make sure that this does
not regress. And then I just wanted to ensure that it passes both with the
Perl version of git add -i as well as with the built-in version.

And in no time I was looking at a real patch series.

Changes since v2:

 * The commit messages of patches 7/11 and 9/11 now stress why we want to
   align the output of the Perl vs the built-in version so slavishly: to be
   able to validate both versions against prerecorded output.
 * A typo was fixed in the commit message of patch 10/11.

Changes since v1:

 * The regression test now actually exercises the re-coloring (that is the
   primary purpose of git add -p looking at the color.diff.* variables).
 * The way the built-in git add -p renders hunk headers of split hunks was
   aligned with how the Perl version does things.
 * We now consistently prefer color.diff.context over color.diff.plain, no
   matter whether using the Perl or the built-in version of git add -p.
 * The commit message for the regression test no longer confuses readers by
   mentioning dash.
 * The regression test was structured a bit better, first testing error
   message coloring, then the menu in git add -i and then the diff coloring
   in git add -p.

Johannes Schindelin (11):
  add -i (built-in): do show an error message for incorrect inputs
  add -i (built-in): send error messages to stderr
  add -p (built-in): imitate `xdl_format_hunk_hdr()` generating hunk
    headers
  add -i: use `reset_color` consistently
  add -i (built-in): prevent the `reset` "color" from being configured
  add -i (built-in): use correct names to load color.diff.* config
  add -p (built-in): do not color the progress indicator separately
  add -i (built-in): use the same indentation as the Perl version
  add -i (Perl version): color header to match the C version
  add -p: prefer color.diff.context over color.diff.plain
  add -i: verify in the tests that colors can be overridden
