Availability:built-in

with_tty_raw(:Goal)

Run goal with the user input and output streams set in raw mode, which implies the terminal makes the input available immediately instead of line-by-line and input that is read is not echoed. As a consequence, line editing does not work. See also get_single_char/1.
