Hi all

I am trying to write some console app
but I found that ncurses/SLang is too big for me,

also it still need to wrote code to process key combination something like
CTRL+ALT+P

What I need is a directly responsed getch();
and a defined keymap.

Is there any sample or issue of that?

thank you very much
your key9

work becoming hard.

Check out Perl's Term::ReadKey.
Search Google and groups.google for more
complex examples.

#!/usr/bin/perl
use warnings;
use strict;
use Term::ReadKey;

#passing ReadKey() an argument of -1 to indicate not to block:

ReadMode('cbreak');

while(1){
my $char;
if (defined ($char = ReadKey(0)) ) {
print "$char->", ord($char),"\n"; # input was waiting and it
was $char
if(ord($char) == 144){ print "Got a Ctrl-Alt-p\n" }

} else {
# no input was waiting
# do whatever
}
}

ReadMode('normal'); # restore normal tty settings
__END__
