NAME MooseX::MarkAsMethods - Mark overload code symbols as methods SYNOPSIS package Foo; use Moose; # mark overloads as methods and wipe other non-methods use MooseX::MarkAsMethods autoclean => 1; # define overloads, etc as normal package Baz; use Moose::Role use MooseX::MarkAsMethods autoclean => 1; # overloads defined in a role will "just work" when the role is # composed into a class # additional methods generated outside Class::MOP/Moose can be marked, too __PACKAGE__->meta->mark_as_method('foo'); package Bar; use Moose; # order is important! use namespace::autoclean; use MooseX::MarkAsMethods; # ... DESCRIPTION MooseX::MarkAsMethods allows one to easily mark certain functions as Moose methods. This will allow other packages such as namespace::autoclean to operate without blowing away your overloads. After using MooseX::MarkAsMethods your overloads will be recognized by Class::MOP as being methods, and class extension as well as composition from roles with overloads will "just work". By default we check for overloads, and mark those functions as methods. If 'autoclean => 1' is passed to import on use'ing this module, we will invoke namespace::autoclean to clear out non-methods. TRAITS APPLIED use'ing this package causes a trait to be applied to your metaclass (for both roles and classes), that provides a mark_as_method() method. You can use this to mark newly generated methods at runtime (e.g. during class composition) that some other package has created for you. mark_as_method() is invoked with one or more names to mark as a method. We die on any error (e.g. name not in symbol table, already a method, etc). e.g. __PACKAGE__->meta->mark_as_method('newly_generated'); e.g. say you have some sugar from another package that creates accessors of some sort; you could mark them as methods via a method modifier: # called as __PACKAGE__->foo_generator('name', ...) after 'foo_generator' => sub { shift->meta->mark_as_method(shift); }; IMPLICATIONS FOR ROLES Using MooseX::MarkAsMethods in a role will cause Moose to track and treat your overloads like any other method defined in the role, and things will "just work". That's it. CAVEATS meta->mark_as_method() You almost certainly don't need or want to do this. CMOP/Moose are fairly good about determining what is and what isn't a method, but not perfect. Before using this method, you should pause and think about why you need to. namespace::autoclean As currently implemented, we run our "method maker" at the end of the calling package's compile scope (B::Hooks::EndOfScope). As namespace::autoclean does the same thing, it's important that if namespace::autoclean is used that it be use'd BEFORE MooseX::MarkAsMethods, so that its end_of_scope block is run after ours. e.g. # yes! use namespace::autoclean; use MooseX::MarkAsMethods; # no -- overloads will be removed use namespace::autoclean; use MooseX::MarkAsMethods; The easiest way to invoke this module and clean out non-methods without having to worry about ordering is: use MooseX::MarkAsMethods autoclean => 1; SEE ALSO overload, B::Hooks::EndOfScope, namespace::autoclean, Class::MOP, Moose. MooseX::Role::WithOverloading does allow for overload application from roles, but it does this by copying the overload symbols from the (not namespace::autoclean'ed role) the symbols handing overloads during class composition; we work by marking the overloads as methods and letting CMOP/Moose handle them.
