Hey Dan!
Your prompt is truly wonderful.
It inspired me to grow up, as far as my shell is concerned.
Based on your design, I came up with this:
if [[ `whoami` = root ]] then
a1="%{$fg_bold[red]%}"
a2="%{$fg_no_bold[red]%}"
else
a1="%{$fg_bold[cyan]%}"
a2="%{$fg_no_bold[cyan]%}"
fi
if [[ $+WINDOW = 1 && $TERM = screen* ]] then
PROMPT="$a1(%n@%m) [$WINDOW] $a2%~ >%{$reset_color%} "
RPROMPT="%D{%H:%M} %D{%d/%m}"
fi
PROMPT="$a1(%n@%m) $a2%~ >%{$reset_color%} "
RPROMPT="%D{%H:%M} %D{%d/%m}"
And I think I'm keeping it like that.
Unless you have any suggestions on how to simply its setup?
It takes up a lot of lines, maybe it could shrink a little.
I hope you don't consider me stealing your design.
If that's the case I'll revert back to my old one.
It's kinda nice though, isn't it? :)
All the best,
Kyrre
