From 738a94a9f645a5f63fbccaab76d5e43a97e53d78 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Tue, 3 Feb 2009 10:20:54 +0100 Subject: bash: offer to show (un)staged changes Add a bit of code to __git_ps1 that lets it append '*' to the branch name if there are any unstaged changes, and '+' if there are any staged changes. Since this is a rather expensive operation and will force a lot of data into the cache whenever you first enter a repository, you have to enable it manually by setting GIT_PS1_SHOWDIRTYSTATE to a nonempty value. The configuration variable bash.showDirtyState can then be used to disable it again for some repositories. Signed-off-by: Thomas Rast Acked-by: Shawn O.
