NAME

       Mouse::Spec - To what extent Mouse is compatible with Moose

VERSION

       This document describes Mouse version 0.99

SYNOPSIS

	   use Mouse::Spec;

	   printf "Mouse/%s is compatible with Moose/%s
",
	       Mouse::Spec->MouseVersion, Mouse::Spec->MooseVersion;

DESCRIPTION

       Mouse is a subset of Moose. This document describes to what extend Mouse is compatible (and incompatible) with Moose.

   Compatibility with Moose
       Sugary APIs

       The sugary APIs are highly compatible with Moose. Methods which have the same name as Moose's are expected to be compatible with Moose's.

       Meta object protocols

       Meta object protocols are a subset of the counterpart of Moose.	Their methods which have the same name as Moose's are expected to be
       compatible with Moose's. Feel free to use these methods even if they are not documented.

       However, there are differences between Moose's MOP and Mouse's.	For example, meta object protocols in Mouse have no attributes by default,
       so "$metaclass->meta->make_immutable()" will not work as you expect.  Don not make metaclasses immutable.

       Mouse::Meta::Instance

       Meta instance mechanism is not implemented, so you cannot change the reftype of Mouse objects in the same way as Moose.

       Role exclusion

       Role exclusion, "exclude()", is not implemented.

       -metaclass in Mouse::Exporter

       "use Mouse -metaclass => ..." are not implemented.  Use "use Mouse -traits => ..." instead.

       Mouse::Meta::Attribute::Native

       Native traits are not supported directly, but "MouseX::NativeTraits" is available on CPAN. Once you have installed it, you can use it as
       the same way in Moose. That is, native traits are automatically loaded by Mouse.

       See MouseX::NativeTraits for details.

   Notes about Moose::Cookbook
       Many recipes in Moose::Cookbook fit Mouse, including:

       o   Moose::Cookbook::Basics::Recipe1 - The (always classic) Point example

       o   Moose::Cookbook::Basics::Recipe2 - A simple BankAccount example

       o   Moose::Cookbook::Basics::Recipe3 - A lazy BinaryTree example

       o   Moose::Cookbook::Basics::Recipe4 - Subtypes, and modeling a simple Company class hierarchy

       o   Moose::Cookbook::Basics::Recipe5 - More subtypes, coercion in a Request class

       o   Moose::Cookbook::Basics::Recipe6 - The augment/inner example

       o   Moose::Cookbook::Basics::Recipe7 - Making Moose fast with immutable

       o   Moose::Cookbook::Basics::Recipe8 - Builder methods and lazy_build

       o   Moose::Cookbook::Basics::Recipe9 - Operator overloading, subtypes, and coercion

       o   Moose::Cookbook::Basics::Recipe10 - Using BUILDARGS and BUILD to hook into object construction

       o   Moose::Cookbook::Roles::Recipe1 - The Moose::Role example

       o   Moose::Cookbook::Roles::Recipe2 - Advanced Role Composition - method exclusion and aliasing

       o   Moose::Cookbook::Roles::Recipe3 - Applying a role to an object instance

       o   Moose::Cookbook::Meta::Recipe2 - A meta-attribute, attributes with labels

       o   Moose::Cookbook::Meta::Recipe3 - Labels implemented via attribute traits

       o   Moose::Cookbook::Extending::Recipe3 - Providing an alternate base object class

NAME

       Moose::Cookbook::Meta::Table_ClassMetaclass - Adding a "table" attribute to the metaclass

VERSION

       version 2.0604

SYNOPSIS

	 package MyApp::Meta::Class;
	 use Moose;
	 extends 'Moose::Meta::Class';

	 has table => (
	     is  => 'rw',
	     isa => 'Str',
	 );

DESCRIPTION

       WARNING: Subclassing metaclasses (as opposed to providing metaclass traits) is strongly discouraged. This recipe is provided solely for
       reference when encountering older code that does this.

       In this recipe, we'll create a new metaclass which has a "table" attribute. This metaclass is for classes associated with a DBMS table, as
       one might do for an ORM.

       In this example, the table name is just a string, but in a real ORM the table might be an object describing the table.

THE METACLASS

       This really is as simple as the recipe "SYNOPSIS" shows. The trick is getting your classes to use this metaclass, and providing some sort
       of sugar for declaring the table. This is covered in Moose::Cookbook::Extending::Recipe2, which shows how to make a module like "Moose.pm"
       itself, with sugar like "has_table()".

   Using this Metaclass in Practice
       Accessing this new "table" attribute is quite simple. Given a class named "MyApp::User", we could simply write the following:

	 my $table = MyApp::User->meta->table;

       As long as "MyApp::User" has arranged to use "MyApp::Meta::Class" as its metaclass, this method call just works. If we want to be more
       careful, we can check the metaclass's class:

	 $table = MyApp::User->meta->table
	     if MyApp::User->meta->isa('MyApp::Meta::Class');

CONCLUSION

       Creating custom metaclass is trivial. Using it is a little harder, and is covered in other recipes. We will also talk about applying traits
       to a class metaclass, which is a more flexible and cooperative implementation.
