To clarify, I am showing an example of what I am trying to do, trimmed down and not functional. As you can see, it's a simple object with a separate thread that keeps reading the output from a program. The thread should exit when the variable $self->{active} turns false, for example by running the method 'stop'.
package Thingee;
use threads;
use threads::shared;
# CONSTRUCTOR
sub new {
local *IN;
my $self = {};
$self->{active} : shared = 1; # SYNTAX ERROR HERE
# This variable must be shared between
# threads.
$self->{in} = undef;
$self->{thread} = undef;
open(*IN, "a_program" ) or $self->{active} = 0;
$self->{in} = *IN;
$self->{thread} = threads->new(\&reader, $self); # Start thread
bless($self);
return $self;
}
# READER (Thread)
sub reader {
my $self = shift;
my $fh = $self->{in};
my $line;
while ( $self->{active} ) {
$line = <$fh>;
print "> $line\n";
}
}
# METHOD
sub stop {
my $self = shift;
$self->{active} = 0;
}
# RETURN TRUE FOR THE USE
1;
