I'm trying to use Module::Pluggable::Ordered to make OOP-based plugins. I
pass parameter (ref to hash) in constructor.
I write this code:
use Module::Pluggable::Ordered search_path => ['Lxctl::plugins::set'],
instantiate => "new";
<...>
sub AUTOLOAD
{
my $self = shift;
my ($function) = $AUTOLOAD =~ m/.*::(.*)$/;
if ($function eq "DESTROY") {
return;
}
for my $plugin ($self->plugins_ordered(\%options)) {
eval {
$plugin->$function(@_);
print "Called $plugin->$function\n";
}
}
}
What I expect:
ref to %options is passed to constructor
What I've got:
Can't use an undefined value as a HASH reference at Lxctl/plugins/set/
base.pm
line 170 (#1)
(F) A value used as either a hard reference or a symbolic reference must
be a defined value. This helps to delurk some insidious errors.
Possible solution:
in Ordered.pm change line 58 from:
--- /usr/share/perl5/Module/Pluggable/Ordered.pm 2011-07-19
02:44:25.576616775 +0400

I don't know perl quite well, so I don't think it's propper fix, but at
least it works for my tasks.
