Here is a demonstration code, which depends on Term::ReadLine::Gnu.

Cheers,



use Term::ReadLine; # automatically loads Term::ReadLine::Gnu, 
                    # which must be present
use Event;
use AnyEvent;

my $term = new Term::ReadLine("Test Event");
my $attribs = $term->Attribs;
$term->callback_handler_install( "> ", sub{ print "got: @_\n" });
my $stdin_watcher = AE::io(*STDIN, 0, 
	sub 
	{ 
		$attribs->{'callback_read_char'}->(); 
	}
);
my $timer = AE::timer(5,0, 
	sub
	{ 
		print "....timed out\n"; 
		$term->rl_deprep_terminal(); # restore usual terminal behavior
		exit;
	}
);
Event::loop();
__END__
