Term::ReadPassword::Win32 kills STDIN

Gulliver has asked for the wisdom of the Perl Monks concerning the following question:

After the call to read_password STDIN stops working. It doesn't wait for user input. Any ideas?

#!/usr/bin/perl
use strict;
use warnings;
use Term::ReadPassword::Win32;
$Term::ReadPassword::Win32::USE_STARS = 1;

my $pass1 = read_password('    sftp password: ');
print "Password:$pass1,\n";
    
print "\nLoad template configuration? \n[Y/n] :";
chomp (my $ans=<STDIN>);   #doesn't wait here for input
print "ans=$ans,,,\n";

Seems it's a known issue, resulting from a Win32::Console bug. The latter report contains a simple patch to Console.pm that purports to fix the issue. Cheers, Rob	[reply]

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; } [download] Also, Term::ReadKey comes standard with Perl. --marmot UPDATE: Fixed a sorta bug. Accidentally introduced an extraneous while loop when I copied the code. Didn't hurt anything but my pride...	[reply] [d/l]

Thanks! Have you considered putting this on cpan?	[reply]

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

On Linux, you also need to check for \n, not only \r `if(ord($key) == 13 \|\| ord($key) == 10) { # if Enter was pressed...` [download]	[reply] [d/l]
