Ultimately, what I want to do is to start a process in a module and parse the output in real time in another script.

What I want to do :

• Open a process Handler (IPC)
• Use this attribute outside of the Module

How I'm trying to do it and fail :

• Open the process handler
• Save the handler in a module's attribute
• Use the attribute outside the module.

Code example :

#module.pm

self->{PROCESS_HANDLER};

sub doSomething{
  ...
  open( self->{PROCESS_HANDLER}, "run a .jar 2>&1 |" );
  ...
}


#perlScript.pl

my $module = new module(...);
...
$module->doSomething();
...
while( $module->{PROCESS_HANDLER} ){
  ...
}
