Subject: [PATCH v6] Support auto-merge for meld to follow the vim-diff behavior
Date: Thu, 02 Jul 2020 00:44:47 +0000 [thread overview]
Message-ID: <pull.781.v6.git.git.1593650687697.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.781.v5.git.git.1593587206520.gitgitgadget@gmail.com>
From: Lin Sun <lin.sun@zoom.us>
Make the mergetool used with "meld" backend behave similarly to how
"vimdiff" behavior by telling it to auto-merge parts without conflicts
and highlight the parts with conflicts when configuring
`mergetool.meld.useAutoMerge` with `true`, or `auto` for automatically
detecting the option.

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.
