Subject: [PATCH 11/15] for-each-ref: introduce %(HEAD) marker
Date: Tue,  9 Jul 2013 16:02:22 +0530	[thread overview]
Message-ID: <1373365946-9230-12-git-send-email-artagnon@gmail.com> (raw)
In-Reply-To: <1373365946-9230-1-git-send-email-artagnon@gmail.com>

'git branch' shows which branch you are currently on with an '*', but
'git for-each-ref' misses this feature.  So, extend the format with
%(HEAD) to do exactly the same thing.

Now you can use the following format in for-each-ref:

  %C(red)%(HEAD)%C(reset) %C(green)%(refname:short)%C(reset)

to display a red asterisk next to the current ref.

 In addition to the above, for commit and tag objects, the header
 field names (`tree`, `parent`, `object`, `type`, and `tag`) can
 be used to specify the value in the header field.
