How to get the width of terminal window in Ruby

Question

Have you ever noticed that if you run rake -T in rails the list of rake descriptions are truncated by the width of the terminal window. So there should be a way to get it in Rub

Answer 1

Ruby actually comes with a built-in class called "Curses", which lets you do all kinds of things with the terminal window.

For example, you can do this:

require 'curses'

Curses.init_screen()

puts Curses.lines # Gives you the height of terminal window
puts Curses.cols # Gives you the width of terminal window
