Zsh Theme For Pragmata Pro

Having spent a lot of money on purchasing the Pragmata Pro font (mostly to acquire a well-made set of glyphs for things like lambdas etc, I decided to allow this font to supplement my zsh theme. Here's the results.

This file is updated often and available on Github here.

#!/usr/bin/env zsh

local LAMBDA="%(?,%{$fg_bold[green]%}λ,%{$fg_bold[red]%}λ)"
if [[ "$USER" == "root" ]]; then USERCOLOR="red"; else USERCOLOR="yellow"; fi

# Git sometimes goes into a detached head state. git_prompt_info doesn't
# return anything in this case. So wrap it in another function and check
# for an empty string.
function check_git_prompt_info() {
  if git rev-parse --git-dir > /dev/null 2>&1; then
    if [[ -z $(git_prompt_info) ]]; then
      echo "%{$fg[blue]%}detached-head%{$reset_color%}) $(git_prompt_status)
%{$fg[yellow]%}→ "
    else
      echo "$(git_prompt_info) $(git_prompt_status)
%{$fg_bold[cyan]%}→ "
    fi
  else
    echo "%{$fg_bold[cyan]%}→ "
  fi
}

function get_right_prompt() {
  if git rev-parse --git-dir > /dev/null 2>&1; then
    echo -n "$(git_prompt_short_sha)%{$reset_color%}"
  else
    echo -n "%{$reset_color%}"
  fi
}

 %{$fg_bold[$USERCOLOR]%}%n\
 %{$fg_no_bold[magenta]%}[%3~]\
 $(check_git_prompt_info)\
