Re: Term::ReadPassword::Win32 kills STDIN

You could also just use Term::ReadKey. I've used it on Win2k, XP, and Vista. It's clumsy to use, but I stuffed it into a utility module I use, like so:

my $pword = get_pword( "Enter password" );
print "Password is '$pword'\n";

sub get_pword {
    use Term::ReadKey;

    my ($prompt) = shift; 
    my $pword;
    my $key;
    local $| = 1;  # Turn off STDOUT buffering for immediate response
    print "$prompt: ";
    ReadMode 4;    # Change to Raw Mode, disable Ctrl-C
    while( 1 ) {
        while (not defined ($key = ReadKey(-1))) { }
        if(ord($key) == 13) { # if Enter was pressed...
            print "\n";       # print a newline
            last;             # and get out of here
        }
        print '*';
        $pword .= $key;
    }
    ReadMode 0; # Reset tty mode before exiting. <==IMPORTANT
    return $pword; 
}

Also, Term::ReadKey comes standard with Perl.

UPDATE: Fixed a sorta bug. Accidentally introduced an extraneous while loop when I copied the code. Didn't hurt anything but my pride...

Thanks! Have you considered putting this on cpan?

This and several other solutions are addressed in perlfaq8. It turns out to be surprisingly platform-dependent.

On Linux, you also need to check for \n, not only \r




if(ord($key) == 13 || ord($key) == 10) { # if Enter was pressed...
