# Get current git branch name
parse_git_branch() {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}

# Format Terminal input prefix
export PS1="\W\[\033[32m\]\$(parse_git_branch)\[\033[00m\] $ "

# Load RVM into a shell session *as a function*
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
