module Kernel
require "highline/import"
adds shortcut methods to
Kernel, making agree(), ask(), choose() and say()
globally available. This is handy for quick and dirty input and output.
These methods use the HighLine object in the
global variable $terminal
, which is initialized to used
$stdin
and $stdout
(you are free to change this).
Otherwise, these methods are identical to their HighLine counterparts, see that class for detailed
explanations.
