Re^2: Reading non-blockingly / "awk has to be better for something."

[james2vegas]

When using Gtk2 I normally use the AnyEvent wrapper over that, especially for its AnyEvent::Handle's methods which let you define reading by line as you wish. But keeping with plain Gtk2 you can just, with your $fh set non-blocking, call sysread with the maximum expected length of your data, like this:

use IO::Handle;
my $fh = *STDIN;
$fh->blocking(0);
while (1) {  # this block would go in your callback, not in a loop lik
+e this:
  $fh->sysread( my $data, 255 ); 
  print "$data";   # split $data into lines on CR|LF put the first lin
+e on the end of the last line of the previous block (use an array per
+haps)
}
