Subject: [PATCH v7 16/17] branch: use ref-filter printing APIs
Date: Wed, 9 Nov 2016 01:42:10 +0530 [thread overview]
Message-ID: <20161108201211.25213-17-Karthik.188@gmail.com> (raw)
In-Reply-To: <20161108201211.25213-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Port branch.c to use ref-filter APIs for printing. This clears out
most of the code used in branch.c for printing and replaces them with
calls made to the ref-filter library.
Introduce build_format() which gets the format required for printing
of refs. Make amendments to print_ref_list() to reflect these changes.
Change calc_maxwidth() to also account for the length of HEAD ref, by
calling ref-filter:get_head_discription().
Also change the test in t6040 to reflect the changes.
Before this patch, all cross-prefix symrefs weren't shortened. Since
we're using ref-filter APIs, we shorten all symrefs by default. We also
allow the user to change the format if needed with the introduction of
the '--format' option in the next patch.
