From fca416a41e90be0102b48949522ff0d2dc258c53 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Thu, 9 Oct 2014 13:45:21 -0700 Subject: completion: use "git -C $there" instead of (cd $there && git ...) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We have had "git -C $there" to first go to a different directory and run a Git command without changing the arguments for quite some time. Use it instead of (cd $there && git ...) in the completion script. This allows us to lose the work-around for misfeatures of modern interactive-minded shells that make "cd" unusable in scripts (e.g. end users' $CDPATH taking us to unexpected places in any POSIX shell, and chpwd functions spewing unwanted output in zsh). Based on Øystein Walle's idea, which was raised during the discussion on the solution by Brandon Turner for a problem zsh users had with RVM which mucks with chpwd_functions in users' environments (https://github.com/wayneeseguin/rvm/issues/3076). As $root variable, which is used to direct where to chdir to, is set to "." based on if $2 to __git_index_files is set (not if it is empty), the only caller of the function is fixed not to pass the optional $2 when it does not want us to switch to a different directory. Otherwise we would end up doing "git -C '' command...", which would not work. Maybe we would want "git -C '' command..." to mean "do not chdir anywhere", but that is a spearate topic.
