DESCRIPTION

There are several ways to use this module. The most straightforward is to just "use MooseX::NonMoose;" in your class; this should set up everything necessary for extending non-Moose modules. MooseX::NonMoose::Meta::Role::Class and MooseX::NonMoose::Meta::Role::Constructor can also be applied to your metaclasses manually, either by passing a "-traits" option to your "use Moose;" line, or by applying them using Moose::Util::MetaRole in a Moose::Exporter-based package. MooseX::NonMoose::Meta::Role::Class is the part that provides the main functionality of this module; if you don't care about inlining, this is all you need to worry about. Applying MooseX::NonMoose::Meta::Role::Constructor as well will provide an inlined constructor when you immutabilize your class.

"MooseX::NonMoose" allows you to manipulate the argument list that gets passed to the superclass constructor by defining a "FOREIGNBUILDARGS" method. This is called with the same argument list as the "BUILDARGS" method, but should return a list of arguments to pass to the superclass constructor. This allows "MooseX::NonMoose" to support superclasses whose constructors would get confused by the extra arguments that Moose requires (for attributes, etc.)

Not all non-Moose classes use "new" as the name of their constructor. This module allows you to extend these classes by explicitly stating which method is the constructor, during the call to "extends". The syntax looks like this:

  extends 'Foo' => { -constructor_name => 'create' };

similar to how you can already pass "-version" in the "extends" call in a similar way.

BUGS/CAVEATS

• The reference that the non-Moose class uses as its instance type must match the instance type that Moose is using. Moose's default instance type is a hashref, but other modules exist to make Moose use other instance types. MooseX::InsideOut is the most general solution - it should work with any class. For globref-based classes in particular, MooseX::GlobRef will also allow Moose to work. For more information, see the "032-moosex-insideout" and "033-moosex-globref" tests bundled with this dist.
• Modifying your class' @ISA after an initial "extends" call will potentially cause problems if any of those new entries in the @ISA override the constructor. "MooseX::NonMoose" wraps the nearest "new()" method at the time "extends" is called and will not see any other "new()" methods in the @ISA hierarchy.
• Completely overriding the constructor in a class using "MooseX::NonMoose" (i.e. using "sub new { ... }") currently doesn't work, although using method modifiers on the constructor should work identically to normal Moose classes.
