### Segment drawing
# A few utility functions to make it easy and re-usable to draw segmented prompts
CURRENT_BG='NONE'
SEGMENT_SEPARATOR=''
# Begin a segment
# Takes two arguments, background and foreground. Both can be omitted,
# rendering default background/foreground.

local bg fg
[[ -n $1 ]] && bg="%K{$1}" || bg="%k"
[[ -n $2 ]] && fg="%F{$2}" || fg="%f"
if [[ $CURRENT_BG != 'NONE' && $1 != $CURRENT_BG ]]; then
echo -n " %{$bg%F{$CURRENT_BG}%}$SEGMENT_SEPARATOR%{$fg%} "
else
echo -n "%{$bg%}%{$fg%} "
# echo $(pwd | sed -e "s,^$HOME,~," | sed "s@\(.\)[^/]*/@\1/@g")
# echo $(pwd | sed -e "s,^$HOME,~,")
fi
CURRENT_BG=$1
[[ -n $3 ]] && echo -n $3
}
# End the prompt, closing any open segments
prompt_end() {
