patch 9.1.0016: default diff highlighting is too noisy Commit: https://github.com/vim/vim/commit/124371c5a149a8c0c75c04b6c90ac11e71a0aa97 Author: Romain Lafourcade <romain.lafourcade@razorfish.fr> Date: Sun Jan 7 15:08:31 2024 +0100 patch 9.1.0016: default diff highlighting is too noisy Problem: default diff highlighting is too noisy Solution: Link diff highlighting groups to new Added/Removed/Changed, revert previous change (Romain Lafourcade) Remove diff* links added in #13776 and doc added in commit b1392be The links added in #13776 are way too noisy for the contexts in which the `diff` syntax is applied (git commits, patches, etc.). This commit: - removes those links - adds new default highlighting groups Added, Changed and Removed - links the diff highlighting groups to those new defaults - removes the doc changes - adjusts the syntax_completion test for those newly added group names Note: Changes to the default color schemes will be handled separately, by adding links to those newly created Added/Removed/Changed highlighting groups. related: #13776 closes #13825 Signed-off-by: Romain Lafourcade <romain.lafourcade@razorfish.fr> Signed-off-by: Christian Brabandt <cb@256bit.org>

The files in this directory come from the xdiff implementation in git.
You can find it here: https://github.com/git/git/tree/master/xdiff
The files were last updated March 17, 2023 from git release v.2.40.0

This is originally based on libxdiff, which can be found here:
http://www.xmailserver.org/xdiff-lib.html

The git version was used because it has been maintained and improved.
And since it's part of git it is expected to be reliable.

The code is distributed under the GNU LGPL license.  It is included in the
COPYING file.

Changes in these files were made to avoid compiler warnings.

The /* */ comments are kept to make syncing to a newer version easier, do not
change them to // comments!

The first work for including xdiff in Vim was done by Christian Brabandt.
