# Add the following to ~/.bashrc

function parse_git_dirty() {
  [[ $(git status 2> /dev/null | tail -n1) != "nothing to commit (working directory clean)" ]] && echo "*"
}
function ps1_git() {
  git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/*\( .*\)/\1$(parse_git_dirty)/"
}
function ps1_rvm() {
  [[ $(~/.rvm/bin/rvm-prompt g) != "@${PWD##*/}" ]] && echo "*"
}

# Replace the PS1 value with:
PS1="\[\033[1;32m\]Foo/\j \[\033[1;33m\]\W\$(ps1_rvm)\[\033[1;34m\]\$(ps1_git) \[\033[00m\]\$ "

# \[\033[1;32m\]               - Switch to green text
# Foo                          - I prefer to give my comps a unique name in the prompt rather than muck around with changing the hostname
# \j                           - Display how many background jobs are running.
# \[\033[1;33m\]               - Yellow text
# \W                           - Display the current directory - I prefer this to the path as otherwise my prompt gets too long
# \$(ps1_rvm)                  - Display an asterisk if the current directory and the current rvm gemset are not the same. I give my gemsets the same name as my projects.
# \[\033[1;34m\]               - Blue text
# \$(ps1_git)                  - Display the git branch when in a git repo with an asterisk if there are uncommitted files
# \[\033[00m\]                 - Back to white text
