Simple way to display title of focused window in i3blocks about i3blocks HOT 2 OPEN

Hello, I used to use unbuffer xtitle -s -t 50 where 50 is the length of the window.

This works well but sometimes de-syncs requiring a quick i3 reload. I now run polybar in the background to stdout as the window command in i3blocks polybar -q --stdout | grep -o -P '(?<=%{l}).*(?=%{PR})' however still the face issue just left often. Let me know how you get on!

Sorry for the late reply ;-)

This is more viable script and does work.

#!/bin/bash
# A simple blocket that prints window title in center of panel.
# Very much dependant on guessing the total length?

window_title=$(xdotool getactivewindow getwindowname)

# Estimation of characters in the block (modify this as per your estimate)
total_length=200 

length=${#window_title}
padding_length=$(( total_length - length ))

# Generate the padding string with underscores
padding=$(printf ' %.0s' $(seq 1 $padding_length))

# Print the window title followed by the padding string
echo  "$window_title $padding"

This is a bit of trial and error as finding the 'center' of screen depends on quite a few variables and calculations.

Based total_length by pure guess work.
