Ok, sorry about that. The way I mentioned probably shouldn't have given you
redefined errors, since it uses an anonymous subroutine. You probably could've
done the same with yours as well without the need for RAWPERL.
For example:
my $mycrunch = sub{
use IPC::Run3 qw(run3);
my $text = shift;
my $output;
run3 ['perl', 'lib/compact_css.pl'], \$text, \$output;
return $output;
};
$context->define_filter(
MyCrunch => $mycrunch,
);
