Subject: [PATCH v5 2/2] format-patch: configure a command to generate the output directory name
Date: Mon, 21 Oct 2019 12:25:23 +0200 [thread overview]
Message-ID: <d461ae79c23ded9cc570ba1856cbae4ca227a711.1571653441.git.bert.wesarg@googlemail.com> (raw)
In-Reply-To: <ac3cc3df4452355dc41c58fe94961c37ca09ebec.1571653441.git.bert.wesarg@googlemail.com>
The 'format.outputDirectory' configuration is only able to store constant
directory names. Though some may use
$ git format-patch -o $(createdir) …
to name the directory dynamically. Provide a new configuration to be able
to store such a command too.
