Takes the default macOS zsh prompt and adds colour to the path, a branch name if present, and marks that changes are made if true.

"Installing"

Add (or create) the following to the ~/.zshrc file.

# ~/.zshrc

autoload -Uz vcs_info # enable vcs_info
precmd () { vcs_info } # always load before displaying the prompt
zstyle ':vcs_info:*' formats ' (%F{34}%{⤴%G%} %b%f)'

function parse_git_dirty {
  inside_git_repo="$(git rev-parse --is-inside-work-tree 2>/dev/null)"

  if [ "$inside_git_repo" ]; then 
    if git diff-index --quiet HEAD
    then
      echo ""
    else
      echo " ●"
    fi
  else
    echo ""
  fi
}

setopt PROMPT_SUBST
export PROMPT='%n@%m %F{220}%1~%f${vcs_info_msg_0_}%F{202}$(parse_git_dirty)%f %% '
