Subject: [PATCH v16] Support auto-merge for meld to follow the vim-diff behavior
Date: Sun, 12 Jul 2020 09:08:23 +0000 [thread overview]
Message-ID: <pull.781.v16.git.git.1594544903477.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.781.v15.git.git.1594543148959.gitgitgadget@gmail.com>
From: Lin Sun <lin.sun@zoom.us>
Make the mergetool used with "meld" backend behave similarly to "vimdiff" by
telling it to auto-merge non-conflicting parts and highlight the conflicting
parts when `mergetool.meld.useAutoMerge` is configured with `true`, or `auto`
for detecting the `--auto-merge` option automatically.

Enable auto-merge for meld to follow the vimdiff beharior
Hi, the mergetool "meld" does NOT merge the no-conflict changes, while
the mergetool "vimdiff" will merge the no-conflict changes and highlight
the conflict parts. This patch will make the mergetool "meld" similar to
"vimdiff", auto-merge the no-conflict changes, highlight conflict parts.
