IPC, buffering, and Win32


P

perl coder

I'm trying to run an external program in Windows (with ActivePerl),
using the piped-open method:

open (PIPE, $cmd_line);
while (<PIPE>) {
# process data
}

All is well and good when my code is run from a shell window, but when I
make a shell-less version (it's a Perl/Tk program compiled with the -gui
argument in perlapp), the data becomes buffered, and that really cramps
my style. :-(

I know that you can trick a program to believe it's running on a
terminal using IO::pty or Expect, but there doesn't seem to be a PPM for
those modules in ActivePerl 5.8! At least I don't see anything at
http://ppm.activestate.com/PPMPackages/zips/8xx-builds-only/Windows/
even though there seems to be compiled versions for Perl 5.6...

Did Perl 5.8 break those modules, or did they forget to compile them, or
are they available somewhere else?
