Subject: [PATCH 12/15] for-each-ref: introduce %(upstream:track[short])
Date: Tue, 9 Jul 2013 16:02:23 +0530 [thread overview]
Message-ID: <1373365946-9230-13-git-send-email-artagnon@gmail.com> (raw)
In-Reply-To: <1373365946-9230-1-git-send-email-artagnon@gmail.com>
Introduce %(upstream:track) to display "[ahead M, behind N]" and
%(upstream:trackshort) to display "=", ">", "<", or "<>"
appropriately (inspired by the contrib/completion/git-prompt.sh).
Now you can use the following format in for-each-ref:
%C(green)%(refname:short)%C(reset)%(upstream:trackshort)
to display refs with terse tracking information.
Note that :track and :trackshort only work with upstream, and error out
when used with anything else.
