Greetings Monks,

Ok, I'm trying to do this Console/Teminal interaction shell... So far I've done the following which is the closest I've gotten to what I want:
#!/usr/bin/perl use Term::ReadKey; use strict; use warnings; startListening(); #$| = 1; #$|++; #select(STDOUT); #$| = 1; sub startListening { # Disable CTRL keys ReadMode(4); my $word = ''; print "> "; while(1) { my $char; if (defined ($char = ReadKey(0))){ print $char; } my $ord = ord($char); last if ($ord == 3); if ($ord == 10 or $ord == 13) { # "Enter" enterPressed($word); $word = ""; print "> "; next; } elsif ($ord == 127) { # ie "Backspace" #chop($word); #print chr(8),' ',chr(8); print "BACKSPACE!\n"; next; } elsif ($ord == 27) { #clearstream(); #$ord="\0"; } elsif ($ord == 8) { print "BACKSPACE!\n"; } #if($ord != "\0"){ #$word .= chr($ord); #print '*'; #} } ReadMode(0); } sub clearstream { while(1) { my $char; if (defined ($char = ReadKey(-1)) ){}else{return} } return; } sub enterPressed { my $word = shift; print "WORD: " . $word . "\n"; }
Now, the problem I have here running this in Window XP, is that I have to press another key (several times) just after a Enter/Return press to show the "WORD..." output. Why is that and how to fix this? Seems like its cached or not flushed properly?

I've tested out with ReadMode(0); but then I can't make the "BACKSPACE!" work. Although I may not need all those special keys, it would be nice to make it work just in case...

Oh, and yea, I know about Term::ReadLine and all those Zoid and Gnu submodules... but Zoid didn't really work in Windows... Got some wierd output by keypress which I shouldn't get... And, with ReadKey its not that big step to make it work as ReadLine (that is, save all keypresses in a scalar, and use this "command" saved in a scalar when enter is pressed)...plus that ReadKey can be non-blocking aswell!

Thanks,
Ace
