NAME
Moose::Cookbook - How to cook a Moose
DESCRIPTION
The Moose cookbook is a series of recipes showing various Moose features. Most recipes
present some code demonstrating some feature, and then explain the details of the code.
You should probably read the Moose::Manual first. The manual explains Moose concepts
without being too code-heavy.
RECIPES
Basic Moose
These recipes will give you a good overview of Moose's capabilities, starting with simple
attribute declaration, and moving on to more powerful features like laziness, types, type
coercion, method modifiers, and more.
Moose::Cookbook::Basics::Recipe1 - The (always classic) Point example
A simple Moose-based class. Demonstrates Moose attributes and subclassing.
Moose::Cookbook::Basics::Recipe2 - A simple BankAccount example
A slightly more complex Moose class. Demonstrates using a method modifier in a
subclass.
Moose::Cookbook::Basics::Recipe3 - A lazy BinaryTree example
Demonstrates several attribute features, including types, weak references, predicates
("does this object have a foo?"), defaults, laziness, and triggers.
Moose::Cookbook::Basics::Recipe4 - Subtypes, and modeling a simple Company class hierarchy
Introduces the creation and use of custom types, a "BUILD" method, and the use of
"override" in a subclass.
Moose::Cookbook::Basics::Recipe5 - More subtypes, coercion in a Request class
More type examples, including the use of type coercions.
Moose::Cookbook::Basics::Recipe6 - The augment/inner example
Demonstrates the use of "augment" method modifiers, a way of turning the usual method
overriding style "inside-out".
Moose::Cookbook::Basics::Recipe7 - Making Moose fast with immutable
Making a class immutable greatly increases the speed of accessors and object
construction.
Moose::Cookbook::Basics::Recipe8 - Builder methods and lazy_build
The builder feature provides an inheritable and role-composable way to provide a
default attribute value.
Moose::Cookbook::Basics::Recipe9 - Operator overloading, subtypes, and coercion
Demonstrates using operator overloading, coercion, and subtypes to model how eye color
is determined during reproduction.
Moose::Cookbook::Basics::Recipe10 - Using BUILDARGS and BUILD to hook into object
construction
This recipe demonstrates the use of "BUILDARGS" and "BUILD" to hook into object
construction.
Moose::Cookbook::Basics::Recipe11 - Extending a non-Moose base class
In this recipe, we make a Moose-based subclass of DateTime, a module which does not
use Moose itself.
Moose Roles
These recipes will show you how to use Moose roles.
Moose::Cookbook::Roles::Recipe1 - The Moose::Role example
Demonstrates roles, which are also sometimes known as traits or mix-ins. Roles provide
a method of code re-use which is orthogonal to subclassing.
Moose::Cookbook::Roles::Recipe2 - Advanced Role Composition - method exclusion and
aliasing
Sometimes you just want to include part of a role in your class. Sometimes you want
the whole role but one of its methods conflicts with one in your class. With method
exclusion and aliasing, you can work around these problems.
Moose::Cookbook::Roles::Recipe3 - Applying a role to an object instance
In this recipe, we apply a role to an existing object instance.
Meta Moose
These recipes show you how to write your own meta classes, which lets you extend the
object system provided by Moose.
Moose::Cookbook::Meta::Recipe1 - Welcome to the meta-world (Why Go Meta?)
If you're wondering what all this "meta" stuff is, and why you should care about it,
read this "recipe".
Moose::Cookbook::Meta::Recipe2 - A meta-attribute, attributes with labels
One way to extend Moose is to provide your own attribute metaclasses. Attribute
metaclasses let you extend attribute declarations (with "has") and behavior to provide
additional attribute functionality.
Moose::Cookbook::Meta::Recipe3 - Labels implemented via attribute traits
Extending Moose's attribute metaclass is a great way to add functionality. However,
attributes can only have one metaclass. Applying roles to the attribute metaclass
lets you provide composable attribute functionality.
Moose::Cookbook::Meta::Recipe4 - Adding a "table" attribute to the metaclass
If you want to store more information about your classes, you'll have to extend
"Moose::Meta::Class". Doing so is simple, but you'll probably also want to provide
some sugar, so see Moose::Cookbook::Extending::Recipe2 as well.
Moose::Cookbook::Meta::Recipe5 - The "table" attribute implemented as a metaclass trait
This recipe takes the class metaclass we saw in the previous recipe and reimplements
it as a metaclass trait.
Moose::Cookbook::Meta::Recipe6 - A method metaclass for marking methods public or private
This recipe shows a custom method metaclass that implements making a method private.
Moose::Cookbook::Meta::Recipe7 - Using a blessed array reference as an object instance
This recipe shows an example of how you create your own meta-instance class. The meta-
instance determines the internal structure of object instances and provide access to
attribute slots.
Moose::Cookbook::Meta::Recipe8 - Hooking into immutabilization (TODO)
Moose has a feature known as "immutabilization". By calling
"__PACKAGE__->meta()->make_immutable()" after defining your class (attributes, roles,
etc), you tell Moose to optimize things like object creation, attribute access, and so
on.
If you are creating your own metaclasses, you may need to hook into the
immutabilization system. This cuts across a number of spots, including the metaclass
class, meta method classes, and possibly the meta-instance class as well.
This recipe shows you how to write extensions which immutabilize properly.
Extending Moose
These recipes cover some more ways to extend Moose, and will be useful if you plan to
write your own "MooseX" module.
Moose::Cookbook::Extending::Recipe1 - Moose extension overview
There are quite a few ways to extend Moose. This recipe provides an overview of each
method, and provides recommendations for when each is appropriate.
Moose::Cookbook::Extending::Recipe2 - Providing a base object class role
Many base object class extensions can be implemented as roles. This example shows how
to provide a base object class debugging role that is applied to any class that uses a
notional "MooseX::Debugging" module.
Moose::Cookbook::Extending::Recipe3 - Providing an alternate base object class
You may find that you want to provide an alternate base object class along with a meta
extension, or maybe you just want to add some functionality to all your classes
without typing "extends 'MyApp::Base'" over and over.
Moose::Cookbook::Extending::Recipe4 - Acting like Moose.pm and providing sugar Moose-style
This recipe shows how to provide a replacement for "Moose.pm". You may want to do this
as part of the API for a "MooseX" module, especially if you want to default to a new
metaclass class or base object class.
