+# Prompt coloring for macOS ZSH
+
+The snippet below modifies the `zsh` prompt by setting a green color for the name (hardcoded to my name here), magenta for path (only shows current folder name), followed by git branch name (if any) color coded by status.
+This is basically just a copy of [this template](https://gist.github.com/chrisnolet/d3582cd63eb3d7b4fcb4d5975fd91d04) by [Chris Nolet](https://gist.github.com/chrisnolet) but with slight modifications for my own purposees.
+To use, add the following lines to `.zshrc`:
+
+```zsh
+autoload -Uz compinit && compinit
+autoload -Uz add-zsh-hook
+autoload -Uz vcs_info
+
+add-zsh-hook precmd vcs_info
+
+zstyle ':vcs_info:*' enable git
+zstyle ':vcs_info:*' formats " %F{cyan}%c%u(%b)%f"
+zstyle ':vcs_info:*' actionformats " %F{cyan}%c%u(%b)%f %a"
+zstyle ':vcs_info:*' stagedstr "%F{green}"
+zstyle ':vcs_info:*' unstagedstr "%F{red}"
+zstyle ':vcs_info:*' check-for-changes true
+
+zstyle ':vcs_info:git*+set-message:*' hooks git-untracked
+
++vi-git-untracked() {
+  if git --no-optional-locks status --porcelain 2> /dev/null | grep -q "^??"; then
+    hook_com[staged]+="%F{red}"
+  fi
+}
+
+setopt PROMPT_SUBST
+export PROMPT='%F{green}ajinkya%f:%F{magenta}%1~%f$vcs_info_msg_0_ %# '
