Subject: [GSoC][PATCH 3/5 v3] submodule: port set_name_rev() from shell to C
Date: Sat, 1 Jul 2017 01:17:25 +0530 [thread overview]
Message-ID: <20170630194727.29787-3-pc44800@gmail.com> (raw)
In-Reply-To: <20170630194727.29787-1-pc44800@gmail.com>
Function set_name_rev() is ported from git-submodule to the
submodule--helper builtin. The function get_name_rev() generates the
value of the revision name as required, and the function
print_name_rev() handles the formating and printing of the obtained
revision name.
