6 Moose::Cookbook - How to cook a Moose
10 The Moose cookbook is a series of recipes showing various Moose
11 features. Most recipes present some code demonstrating some feature,
12 and then explain the details of the code.
14 You should probably read the L<Moose::Manual> first. The manual
15 explains Moose concepts without being too code-heavy.
21 These recipes will give you a good idea of what Moose is capable,
22 starting with simple attribute declaration, and moving on to more
23 powerful features like laziness, types, type coercion, method
28 =item L<Moose::Cookbook::Basics::Recipe1> - The (always classic) B<Point> example
30 A simple Moose-based class. Demonstrated Moose attributes and subclassing.
32 =item L<Moose::Cookbook::Basics::Recipe2> - A simple B<BankAccount> example
34 A slightly more complex Moose class. Demonstrates using a method
35 modifier in a subclass.
37 =item L<Moose::Cookbook::Basics::Recipe3> - A lazy B<BinaryTree> example
39 Demonstrates several attribute features, including types, weak
40 references, predicates ("does this object have a foo?"), defaults,
41 laziness, and triggers.
43 =item L<Moose::Cookbook::Basics::Recipe4> - Subtypes, and modeling a simple B<Company> class hierarchy
45 Introduces the creation and use of custom types, a C<BUILD> method,
46 and the use of C<override> in a subclass.
48 =item L<Moose::Cookbook::Basics::Recipe5> - More subtypes, coercion in a B<Request> class
50 More type examples, including the use of type coercions.
52 =item L<Moose::Cookbook::Basics::Recipe6> - The augment/inner example
54 Demonstrates the use of C<augment> method modifiers, a way of turning
55 the usual method overriding style "inside-out".
57 =item L<Moose::Cookbook::Basics::Recipe7> - Making Moose fast with immutable
59 Making a class immutable greatly increases the speed of accessors and
62 =item L<Moose::Cookbook::Basics::Recipe8> - Managing complex relations with trigger (TODO)
66 Work off of this http://code2.0beta.co.uk/moose/svn/Moose/trunk/t/200_examples/007_Child_Parent_attr_inherit.t
68 =item L<Moose::Cookbook::Basics::Recipe9> - Builder methods and lazy_build
70 The builder feature provides an inheritable and role-composable way to
71 provide a default attribute value.
73 =item L<Moose::Cookbook::Basics::Recipe10> - Operator overloading, subtypes, and coercion
75 Demonstrates using operator overloading, coercion, and subtypes to
76 model how eye color is determined during reproduction.
78 =item L<Moose::Cookbook::Basics::Recipe11> - Using BUILDARGS and BUILD to hook into object construction
80 This recipe demonstrates the use of C<BUILDARGS> and C<BUILD> to hook
81 into object construction.
87 These recipes will show you how to use Moose roles.
91 =item L<Moose::Cookbook::Roles::Recipe1> - The Moose::Role example
93 Demonstrates roles, which are also sometimes known as traits or
94 mix-ins. Roles provide a method of code re-use which is orthogonal to
97 =item L<Moose::Cookbook::Roles::Recipe2> - Advanced Role Composition - method exclusion and aliasing
99 Sometimes you just want to include part of a role in your
100 class. Sometimes you want the whole role but one if its methods
101 conflicts with one in your class. With method exclusion and aliasing,
102 you can work around these problems.
104 =item L<Moose::Cookbook::Roles::Recipe3> - Applying a role to an object instance
106 In this recipe, we apply a role to an existing object instance.
112 These recipes show you how to write your own meta classes, which lets
113 you extend the object system provide by Moose.
117 =item L<Moose::Cookbook::Meta::Recipe1> - Welcome to the meta-world (Why Go Meta?)
119 If you're wondering what all this "meta" stuff is, and why you should
120 care about it, read this "recipe".
122 =item L<Moose::Cookbook::Meta::Recipe2> - A meta-attribute, attributes with labels
124 One way to extend Moose is to provide your own attribute
125 metaclasses. Attribute metaclasses let you extend attribute
126 declarations (with C<has>) and behavior to provide additional
127 attribute functionality.
129 =item L<Moose::Cookbook::Meta::Recipe3> - Labels implemented via attribute traits
131 Extending Moose's attribute metaclass is a great way to add
132 functionality. However, attributes can only have one metaclass.
133 Applying roles to the attribute metaclass lets you provide
134 composable attribute functionality.
136 =item L<Moose::Cookbook::Meta::Recipe4> - Adding a "table" attribute to the metaclass
138 If you want to store more information about your classes, you'll have
139 to extend C<Moose::Meta::Class>. Doing so is simple, but you'll
140 probably also want to provide some sugar, so see
141 L<Moose::Cookbook::Extending::Recipe2> as well.
143 =item L<Moose::Cookbook::Meta::Recipe5> - The "table" attribute implemented as a metaclass trait
145 This example takes the class metaclass we saw in the previous recipe
146 and reimplements it as a metaclass trait.
148 =item L<Moose::Cookbook::Meta::Recipe6> - Hooking into the immutabilization system (TODO)
150 Moose has a feature known as "immutabilization". By calling C<<
151 __PACKAGE__->meta()->make_immutable() >> after defining your class
152 (attributes, roles, etc), you tell Moose to optimize things like
153 object creation, attribute access, and so on.
155 If you are creating your own metaclasses, you may need to hook into
156 the immutabilization system. This cuts across a number of spots,
157 including the metaclass class, meta method classes, and possibly the
158 meta-instance class as well.
160 This recipe shows you how to write extensions which immutabilize
163 =item L<Moose::Cookbook::Meta::Recipe7> - I<meta-instance> (TODO)
165 I<abstract goes here>
169 =head2 Extending Moose
171 These recipes cover some more ways to extend Moose, and will be useful
172 if you plan to write your own C<MooseX> module.
176 =item L<Moose::Cookbook::Extending::Recipe1> - Moose extension overview
178 There are quite a number of ways to extend Moose. This recipe explains
179 provides an overview of each method, and provides recommendations for
180 when each is appropriate.
182 =item L<Moose::Cookbook::Extending::Recipe2> - Providing a base object class role
184 Many base object class extensions can be implemented as roles. This
185 example shows how to provide a base object class debugging role that
186 is applied to any class that uses a notional C<MooseX::Debugging>
189 =item L<Moose::Cookbook::Extending::Recipe3> - Providing an alternate base object class
191 You may find that you want to provide an alternate base object class
192 along with a meta extension, or maybe you just want to add some
193 functionality to all your classes without typing C<extends
194 'MyApp::Base'> over and over.
196 =item L<Moose::Cookbook::Extending::Recipe4> - Acting like Moose.pm and providing sugar Moose-style
198 This recipe shows how to provide a replacement for C<Moose.pm>. You
199 may want to do this as part of the API for a C<MooseX> module,
200 especially if you want to default to a new metaclass class or base
