[wxperl-users] Demo>Process

[Graciliano M. P. \(V. Sites\) <gm...@vi...>]

I was looking for I/O redirection of a process for Wx. I saw in the wxPerl
demo something for that, but doen't work!

I got this alert on reading the HANDLE:
readline() on unopened filehandle o at
F:/CVS/wxPerl/wxPerl/demo/wxProcess.pm li
ne 152 (+-)

I'm using Win2K, Perl580 and wxPerl-0.11-wx233. I made another script to
test this:

---------------
  testwxio.pl
---------------

#!/usr/bin/perl

use Wx ;

package MyApp ;

use vars qw(@ISA); @ISA = qw(Wx::App);

sub new {
  my $class = shift;
  my $this = $class->SUPER::new();
  return $this;
}

sub OnInit { 1 }

package main ;

 my $app = MyApp->new() ;

 my $process = Wx::Process->new( $app , -1 );
 $process->Redirect ;

 Wx::ExecuteArgs( [$^X, "test3.pl"], 1 , $process );
# Wx::ExecuteCommand( "$^X test3.pl" , 1 , undef ) ;

 my $stream = $process->GetInputStream ;

 while( 1 ) {
   sysread($stream , $buffer , 1) ;
   print "<$buffer>\n" ;
   sleep(1);
 }

exit;

---------------
  test3.pl
---------------

#!/usr/bin/perl

 for(0..2) {
   print "$_\n" ;
   sleep(1);
 }

 print STDERR "ERROR!!!! \n" ;

exit;
