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::Snack::Types - Snippets of code for using Types and Type Constraints

VERSION

       version 2.0603

SYNOPSIS

	 package Point;
	 use Moose;

	 has 'x' => ( isa => 'Int', is => 'ro' );
	 has 'y' => ( isa => 'Int', is => 'rw' );

	 package main;
	 use Try::Tiny;

	 my $point = try {
	     Point->new( x => 'fifty', y => 'forty' );
	 }
	 catch {
	     print "Oops: $_";
	 };

	 my $point;
	 my $xval	      = 'forty-two';
	 my $xattribute       = Point->meta->find_attribute_by_name('x');
	 my $xtype_constraint = $xattribute->type_constraint;

	 if ( $xtype_constraint->check($xval) ) {
	     $point = Point->new( x => $xval, y => 0 );
	 }
	 else {
	     print "Value: $xval is not an " . $xtype_constraint->name . "
";
	 }

DESCRIPTION

       This is the Point example from Moose::Cookbook::Basics::Point_AttributesAndSubclassing with type checking added.

       If we try to assign a string value to an attribute that is an "Int", Moose will die with an explicit error message. The error will include
       the attribute name, as well as the type constraint name and the value which failed the constraint check.

       We use Try::Tiny to catch this error message.

       Later, we get the Moose::Meta::TypeConstraint object from a Moose::Meta::Attribute and use the Moose::Meta::TypeConstraint to check a value
       directly.
