Subject: [PATCH v5 6/7] difftool: make --gui, --tool and --extcmd mutually exclusive
Date: Mon, 29 Apr 2019 02:21:17 -0400 [thread overview]
Message-ID: <c70789b689937f31bcde333f3d7cbe9099e53a0e.1556518203.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1556518203.git.liu.denton@gmail.com>
In git-difftool, these options specify which tool to ultimately run. As
a result, they are logically conflicting. Explicitly disallow these
options from being used together.
