Term::termios

termios routines for Rakudo Perl 6

use Term::termios;

# Save the previous attrs
my $saved_termios := Term::termios.new(fd => 1).getattr;

# Get the existing attrs in order to modify them

# Set the tty to raw mode

# You could also do the same in the old-fashioned way

# Set the modified atributes, delayed until the buffer is emptied
$termios.setattr(:DRAIN);

# Loop on characters from STDIN
loop {
    my $c = $*IN.getc;
    print "got: " ~ $c.ord ~ "\r\n";

# Restore the saved, previous attributes before exit

See the manpage termios(3) for information about the flags.
