# the idea of this theme is to contain a lot of info in a small string, by
  # compressing some parts and colorcoding, which bring useful visual cues,
  # while limiting the amount of colors and such to keep it easy on the eyes.
  # When a command exited >0, the timestamp will be in red and the exit code
  # will be on the right edge.
  # The exit code visual cues will only display once.
  # (i.e. they will be reset, even if you hit enter a few times on empty command prompts)
