# Configuring Our Prompt
# ======================

  # if you install git via homebrew, or install the bash autocompletion via homebrew, you get __git_ps1 which you can use in the PS1
  # to display the git branch.  it's supposedly a bit faster and cleaner than manually parsing through sed. i dont' know if you care
  # enough to change it

  # This function is called in your prompt to output your active git branch.
  function parse_git_branch {
    git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
