Read a single char from stdin without pressing enter

Question

How can I read a single char from the console without pressing enter / return?

In ruby I would just use:

require 'io/console'
input = STDIN.getch

Try this:

char = STDIN.raw &.read_char
p char

Is there an equivalent of `STDIN.ready?` ? When I am reading Meta/Alt characters or Shifted-Fn keys, I keep reading while `STDIN.ready?` and return with the collected keys when it is not ready. – rahul Apr 30 '19 at 06:55
