Clock3 Prompt

This prompt uses ANSI position codes to put a clock in the upper right corner of your term. It uses different codes than clock, so this works if you have a VGA font in any terminal emulator. However, the body of the prompt is locked to the bottom two rows of the term. If the terminal window is resized, this prompt adjusts itself.

This is probably the most attractive and most useless prompt I've done.

Code:

#   This prompt requires a VGA font.  The prompt is anchored at the bottom
#   of the terminal, fills the width of the terminal, and draws a line up
#   the right side of the terminal to attach itself to a clock in the upper
#   right corner of the terminal.

function prompt_command {
#   Calculate the width of the prompt:
hostnam=$(echo -n $HOSTNAME | sed -e "s/[\.].*//")
#   "whoami" and "pwd" include a trailing newline
usernam=$(whoami)
newPWD="${PWD}"
#   Add all the accessories below ...
let promptsize=$(echo -n "--(${usernam}@${hostnam})---(${PWD})-----" \
                 | wc -c | tr -d " ")
#   Figure out how much to add between user@host and PWD (or how much to
#   remove from PWD)
let fillsize=${COLUMNS}-${promptsize}
fill=""
#   Make the filler if prompt isn't as wide as the terminal:
while [ "$fillsize" -gt "0" ] 
do 
    fill="${fill}"
	let fillsize=${fillsize}-1
done
#   Right-truncate PWD if the prompt is going to be wider than the terminal:
if [ "$fillsize" -lt "0" ]
then
    let cutt=3-${fillsize}
    newPWD="...$(echo -n $PWD | sed -e "s/\(^.\{$cutt\}\)\(.*\)/\2/")"
fi
#
#   Create the clock and the bar that runs up the right side of the term
#
local LIGHT_BLUE="\033[1;34m"
local     YELLOW="\033[1;33m"
#   Position the cursor to print the clock:
echo -en "\033[2;$((${COLUMNS}-9))H"
echo -en "$LIGHT_BLUE($YELLOW$(date +%H%M)$LIGHT_BLUE)\304$YELLOW\304\304\277"
local i=${LINES}
echo -en "\033[2;${COLUMNS}H"
#   Print vertical dashes down the side of the terminal:
while [ $i -ge 4 ]
do
   echo -en "\033[$(($i-1));${COLUMNS}H\263"
   let i=$i-1
done

let prompt_line=${LINES}-1
#   This is needed because doing \${LINES} inside a Bash mathematical
#   expression (ie. $(())) doesn't seem to work.
