6 | Moose::Cookbook - How to cook a Moose |
7 | |
8 | =head1 DESCRIPTION |
9 | |
4711f5f7 |
10 | The Moose cookbook is a series of recipes taken from the Moose |
471c4f09 |
11 | test suite. Each recipe presents some code, which demonstrates |
12 | some of the features of Moose, and then proceeds to explain the |
13 | details of the code. |
14 | |
734d1752 |
15 | We also provide a L<Moose::Cookbook::FAQ> and a L<Moose::Cookbook::WTF> |
16 | for common questions and problems people have with Moose. |

20 | =head2 Basic Moose |
21 | |
4eec354b |
22 | These recipes will give you a good idea of what Moose is capable, |
23 | starting with simple attribute declaration, and moving on to more |
24 | powerful features like laziness, types, type coercion, method |
25 | modifiers, and more. |

29 | =item L<Moose::Cookbook::Basics::Recipe1> - The (always classic) B<Point> example |
471c4f09 |
30 | |
f7f3648d |
31 | A simple Moose-based class. Demonstrated Moose attributes and subclassing. |

33 | =item L<Moose::Cookbook::Basics::Recipe2> - A simple B<BankAccount> example |
471c4f09 |
34 | |
f7f3648d |
35 | A slightly more complex Moose class. Demonstrates using a method |
36 | modifier in a subclass. |
cb2478d4 |
37 | |
021b8139 |
38 | =item L<Moose::Cookbook::Basics::Recipe3> - A lazy B<BinaryTree> example |
471c4f09 |
39 | |
f7f3648d |
40 | Demonstrates several attribute features, including types, weak |
41 | references, predicates ("does this object have a foo?"), defaults, and |
5cfe3805 |
42 | lazy attribute uction. |
cb2478d4 |
43 | |
021b8139 |
44 | =item L<Moose::Cookbook::Basics::Recipe4> - Subtypes, and modeling a simple B<Company> class hierarchy |
471c4f09 |
45 | |
f7f3648d |
46 | Introduces the creation and use of custom types, a C<BUILD> method, |
47 | and the use of C<override> in a subclass. |
cb2478d4 |
48 | |
021b8139 |
49 | =item L<Moose::Cookbook::Basics::Recipe5> - More subtypes, coercion in a B<Request> class |
471c4f09 |
50 | |
f7f3648d |
51 | More type examples, including the use of type coercions. |
cb2478d4 |
52 | |
021b8139 |
53 | =item L<Moose::Cookbook::Basics::Recipe6> - The augment/inner example |
496b74ab |
54 | |
f7f3648d |
55 | Demonstrates the use of C<augment> method modifiers, a way of turning |
56 | the usual method overriding style "inside-out". |
cb2478d4 |

021b8139 |
58 | =item L<Moose::Cookbook::Basics::Recipe7> - Making Moose fast with immutable |
496b74ab |
59 | |
5de2944f |
60 | Making a class immutable greatly increases the speed of accessors and |
61 | object construction. |

71 | The builder feature provides an inheritable and role-composable way to |
72 | provide a default attribute value. |

87 | =item L<Moose::Cookbook::Role::Recipe1> - The Moose::Role example |
496b74ab |
88 | |
f7f3648d |
89 | Demonstrates roles, which are also sometimes known as traits or |
90 | mix-ins. Roles provide a method of code re-use which is orthogonal to |
91 | subclassing. |
cb2478d4 |

496b74ab |
94 | |
2e3d0a0a |
95 | Sometimes you just want to include part of a role in your |
96 | class. Sometimes you want the whole role but one if its methods |
97 | conflicts with one in your class. With method exclusion and aliasing, |
98 | you can work around these problems. |

106 | =head2 Meta Moose |
107 | |
4eec354b |
108 | These recipes show you how to write your own meta classes, which lets |
109 | you extend the object system provide by Moose. |

113 | =item L<Moose::Cookbook::Meta::Recipe1> - Welcome to the meta-world (Why Go Meta?) |
496b74ab |
114 | |

115 | If you're wondering what all this "meta" stuff is, and why you should |
116 | care about it, read this "recipe". |

118 | =item L<Moose::Cookbook::Meta::Recipe2> - A meta-attribute, attributes with labels |
496b74ab |
119 | |
f7f3648d |
120 | One way to extend Moose is to provide your own attribute |
121 | metaclasses. Attribute metaclasses let you extend attribute |
122 | declarations (with C<has>) and behavior to provide additional |
123 | attribute functionality. |
cb2478d4 |

43aa5bf9 |
125 | =item L<Moose::Cookbook::Meta::Recipe3> - Labels implemented via attribute traits |
a7d0cd00 |
126 | |
aff0421c |
127 | Extending Moose's attribute metaclass is a great way to add |
128 | functionality. However, attributes can only have one metaclass. |
129 | Applying roles to the attribute metaclass lets you provide |
130 | composable attribute functionality. |
cb2478d4 |
131 | |

132 | =item L<Moose::Cookbook::Meta::Recipe4> - Adding a "table" attribute to the metaclass |
133 | |
134 | If you want to store more information about your classes, you'll have |
135 | to extend C<Moose::Meta::Class>. Doing so is simple, but you'll |
136 | probably also want to provide some sugar, so see |
c5b9daec |
137 | L<Moose::Cookbook::Extending::Recipe2> as well. |

139 | =item L<Moose::Cookbook::Meta::Recipe5> - The "table" attribute implemented as a metaclass trait |
24a8fe99 |
140 | |
c5b9daec |
141 | This example takes the class metaclass we saw in the previous recipe |
142 | and reimplements it as a metaclass trait. |

144 | =item L<Moose::Cookbook::Meta::Recipe6> - Hooking into the immutabilization system (TODO) |
145 | |
146 | Moose has a feature known as "immutabilization". By calling C<< |
147 | __PACKAGE__->meta()->make_immutable() >> after defining your class |
148 | (attributes, roles, etc), you tell Moose to optimize things like |
149 | object creation, attribute access, and so on. |
150 | |
151 | If you are creating your own metaclasses, you may need to hook into |
152 | the immutabilization system. This cuts across a number of spots, |
153 | including the metaclass class, meta method classes, and possibly the |
154 | meta-instance class as well. |
155 | |
156 | This recipe shows you how to write extensions which immutabilize |
157 | properly. |

165 | =head2 Extending Moose |
166 | |

167 | These recipes cover some more ways to extend Moose, and will be useful |
168 | if you plan to write your own C<MooseX> module. |

172 | =item L<Moose::Cookbook::Extending::Recipe1> - Moose extension overview |
173 | |
174 | There are quite a number of ways to extend Moose. This recipe explains |
175 | provides an overview of each method, and provides recommendations for |
176 | when each is appropriate. |

178 | =item L<Moose::Cookbook::Extending::Recipe2> - Providing a base object class role |
c8d5f1e1 |
179 | |
180 | Many base object class extensions can be implemented as roles. This |
f3ce0579 |
181 | example shows how to provide a base object class debugging role that |
182 | is applied to any class that uses a notional C<MooseX::Debugging> |
183 | module. |
c8d5f1e1 |
184 | |
185 | =item L<Moose::Cookbook::Extending::Recipe3> - Providing an alternate base object class |
6fa0a13f |
186 | |
187 | You may find that you want to provide an alternate base object class |
188 | along with a meta extension, or maybe you just want to add some |
189 | functionality to all your classes without typing C<extends |
190 | 'MyApp::Base'> over and over. |
191 | |
c8d5f1e1 |
192 | =item L<Moose::Cookbook::Extending::Recipe4> - Acting like Moose.pm and providing sugar Moose-style |
6fa0a13f |
193 | |
c5b9daec |
194 | This recipe shows how to provide a replacement for C<Moose.pm>. You |
195 | may want to do this as part of the API for a C<MooseX> module, |
5583dc1c |
196 | especially if you want to default to a new metaclass class or base |
197 | object class. |
