Re: Breaking up a big module

[tobyink]

I've already answered this question, but now I'm typing a second solution.

Foo.pm

package Foo;
use Role::Tiny::With; with "Foo::Bar";
sub aa {
  my ( $self, $args ) = @_;
  my $val = $self->_aa ( $args->{'bar'} );
}
sub bb {
  my ( $self, $args ) = @_;
  my $val = $self->_bb ( $args->{'foo'} );
}
1;

Foo/Bar.pm

package Foo::Bar;
use Role::Tiny;
sub _aa {
  my $self, $quux ) = @_;
}
sub _bb {
  my $self, $fazoo ) = @_;
}
1;

This has the advantage that the methods defined in Foo::Bar are no longer coupled to Foo. If you define a new class called Foo2, and want to have _aa and _bb defined in Foo2 as well, you can just do:

package Foo2;
use Role::Tiny::With; with "Foo::Bar";
...;
1;
