From eb443e3b39482b3d64c1efd46de7481c3321a87a Mon Sep 17 00:00:00 2001 From: Tony Finch Date: Mon, 22 Dec 2014 18:09:25 +0000 Subject: [PATCH] git-prompt: preserve value of $? inside shell prompt If you have a prompt which displays the command exit status, __git_ps1 without this change corrupts it, although it has the correct value in the parent shell: ~/src/git (master) 0 $ set | grep ^PS1 PS1='\w$(__git_ps1) $? \$ ' ~/src/git (master) 0 $ false ~/src/git (master) 0 $ echo $? 1 ~/src/git (master) 0 $ There is a slightly ugly workaround: ~/src/git (master) 0 $ set | grep ^PS1 PS1='\w$(x=$?; __git_ps1; exit $x) $? \$ ' ~/src/git (master) 0 $ false ~/src/git (master) 1 $ This change makes the workaround unnecessary.
