From 0120b8c85c7a52b26ea7062fec349d178a4e0208 Mon Sep 17 00:00:00 2001 From: Jess Austin Date: Tue, 6 Jan 2015 20:22:27 -0500 Subject: [PATCH] git-prompt.sh: allow to hide prompt for ignored pwd Optionally set __git_ps1 to display nothing when present working directory is ignored, triggered by the new environment variable GIT_PS1_HIDE_IF_PWD_IGNORED. This environment variable may be overridden on any repository by setting bash.hideIfPwdIgnored to "false". In the absence of GIT_PS1_HIDE_IF_PWD_IGNORED this change has no effect. Many people manage e.g. dotfiles in their home directory with git. This causes the prompt generated by __git_ps1 to refer to that "top level" repo while working in any descendant directory. That can be distracting, so this patch helps one shut off that noise.
