EDIT: (12-Mar-2010) slight update to the svn prompt code to give a better / more useful output…

I’ve seen things like this posted on the net before but never really had a chance to play with the idea. But as I’m now using git and svn a lot more these days (fingers crossed i’ll be totally free of cvs soon!) I thought it was about time I pulled my finger out.

So here’s the end goal, in a normal directory, we just get a normal bash promt, but in a directory controlled by git or svn, we also get an addition telling us the source control tool in use and the current branch:

So, fire up yer terminal and add the following to your .profile, .bash_profile or .bashrc (whichever one you use):

parse_git_branch () {
	git name-rev HEAD 2> /dev/null | sed 's#HEAD\ \(.*\)# (git::\1)#'
}
parse_svn_branch() {
	parse_svn_url | sed -e 's#^'"$(parse_svn_repository_root)"'##g' | awk '{print " (svn::"$1")" }'
}
parse_svn_url() {
	svn info 2>/dev/null | sed -ne 's#^URL: ##p'
}
parse_svn_repository_root() {
	svn info 2>/dev/null | sed -ne 's#^Repository Root: ##p'
}
 
BLACK="\[\033[0;38m\]"
RED="\[\033[0;31m\]"
RED_BOLD="\[\033[01;31m\]"
BLUE="\[\033[01;34m\]"
GREEN="\[\033[0;32m\]"
 
export PS1="$BLACK[ \u@$RED\h $GREEN\w$RED_BOLD\$(parse_git_branch)\$(parse_svn_branch)$BLACK ] "

Simples. Now just open up a new terminal and move into a project directory using svn or git.
