dietmar is a zsh theme (for ohmyzsh or antigen.sh) based on the themes dieter and mortalscumbag.
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. If you are connected via ssh there will be a notification.
Antigen:
insert into .zshrc
