Re: cross-platform timeout on user input

[THRAK]

I haven't used Term::Prompt, but I did throw this little demo thing together for a former coworker many moons ago. It was written for use on a Unix but should run on WIN (using a WIN cmd obviously) if Term::ReadKey and Term::ReadLine are installed. Note this was written many moons ago, thus no "-w" or "use strict". Hope this might be of some use to you.

#!/usr/bin/perl

use Term::ReadLine;
use Term::ReadKey;

$in = new Term::ReadLine 'LABEL';
$inval = "";
$prompt = " Enter a Unix command.  Enter 'quit' to bailout.\n\n  -> ";
    while ( $inval eq "" ) {
    $inval = $in->readline($prompt);
    }
if ($inval ne "quit") { #Do this
    print "You entered: $inval\n";
    system("$inval");
} else {
    print "You said to quit.\n\nBye!\n";
    $quit = confirm("quit");
    if ($quit eq "n") {
        print "Decided not to quit I see.\n";
    } else {
        print "OK, OK, I'm quitting...\n";
    }
}

pressanykey();
