# color support is limited to your terminal
# for most terminals, valid colors are 000-256
# run 'prompt_fg_samples' and 'prompt_bg_samples' for a preview of the colors
# set these colors to the same color to disable the prompt changing color based on directory
# foreground color for the prompt when in $HOME directory
COLOR_HOME="004"
# foreground color for the prompt when in /usr/* and /opt/*
COLOR_USR="011"
# foreground color for the prompt when in /*
COLOR_ROOT="009"
# background color for the prompt
COLOR_BG="000"
# PROMPT
# set the contents of the prompt
# '%$(FG_COLOR)F' is the color based on the $PWD as set in ~/.zsh_prompt.conf
# '%{$(BG_COLOR $COLOR_BG)%}' is the background color as set in ~/.zsh_prompt.conf
# '%25<$(echo "/${${PWD#/*}%%/*}/" | sed 's%\/home\/%\~\/%')...<%~' truncates the current
# directory if more than 25 characters
# see http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Prompt-Expansion for zsh prompt expansions
