MojoX-Run

SYNOPSIS

 # create executor object
 # NOTE: new *ALWAYS* returns singleton object!
 my $executor = MojoX::Run->new()
 
 # simple usage
 my $pid = $executor->spawn(
 	cmd => "ping -W 2 -c 5 host.example.org",
 	exit_cb => sub {
 		my ($pid, $res) = @_;
 		print "Ping finished with exit status $res->{exit_val}.\n";
 		print "\tSTDOUT:\n$res->{stdout}\n";
 		print "\tSTDERR:\n$res->{stderr}\n";
 	}
 );
 # check for injuries
 unless ($pid) {
 	print "Command startup failed: ", $executor->error(), "\n";
 }
 
 # more complex example...
 my $pid2 = $executor->spawn(
 	cmd => 'ping host.example.org',
 	stdin_cb => sub {
 		my ($pid, $chunk) = @_;
 		print "STDOUT $pid: '$chunk'\n"
 	},
 	# ignore stderr
 	stderr_cb => sub {},
 	exit_cb => sub {
 		my ($pid, $res) = @_;
 		print "Process $res->{cmd} [pid: $pid] finished after $res->{time_duration_exec} second(s).\n";
 		print "Exit status: $res->{exit_status}";
 		print " by signal $res->{exit_signal}" if ($res->{exit_signal});
 		print "with coredump " if ($res->{exit_core});
 		print "\n";
 	}
 );

 # even fancier usage: spawn coderef
 my $pid3 = $executor->spawn(
 	cmd => sub {
 		for (my $i = 0; $i < 10; $i++) {
 			if (rand() > 0.5) {
 				print STDERR rand(), "\n"
 			} else {
 				print rand(), "\n";
 			}
 			sleep int(rand(10));
 		}
 		exit (rand() > 0.5) ? 0 : 1;
 	},
 	exit_cb => {
 		print "Sub exited with $res->{exit_status}, STDOUT: $res->{stdout}\n";
 	},
 );
