Subject: [PATCH v2 04/11] t9903: run pc mode tests again with PS1 expansion disabled
Date: Wed, 4 Jun 2014 17:01:20 -0400 [thread overview]
Message-ID: <1401915687-8602-5-git-send-email-rhansen@bbn.com> (raw)
In-Reply-To: <1401915687-8602-1-git-send-email-rhansen@bbn.com>
Bash has a shell option that makes it possible to disable parameter
expansion in PS1. Test __git_ps1's ability to detect and react to
disabled PS1 expansion by running the "pc mode" tests twice: once
with PS1 parameter expansion enabled and once with it disabled.
