e0da prompt

.zshrc goes in $HOME, everything else goes in $HOME/share, and you want to brew install zsh-git-prompt. I'm using Gruvbox here with macOS Terminal.

if test -t $STDOUT; then
  INTERACTIVE=1

interactive_shell() {

color() {
  if interactive_shell; then
    echo -en "\033[$1;5;$2m"

}

  echo -en "\033[1m"
