6Moose::Cookbook - How to cook a Moose
7
8=head1 DESCRIPTION
9
ad248e00 10The Moose cookbook is a series of recipes showing various Moose
11features. Most recipes present some code demonstrating some feature,
12and then explain the details of the code.
471c4f09 13
ad248e00 14You should probably read the L<Moose::Manual> first. The manual
15explains Moose concepts without being too code-heavy.

18
496b74ab 19=head2 Basic Moose
20
4eec354b 21These recipes will give you a good idea of what Moose is capable,
22starting with simple attribute declaration, and moving on to more
23powerful features like laziness, types, type coercion, method
24modifiers, and more.

471c4f09 26=over 4
27
021b8139 28=item L<Moose::Cookbook::Basics::Recipe1> - The (always classic) B<Point> example
471c4f09 29
f7f3648d 30A simple Moose-based class. Demonstrated Moose attributes and subclassing.
cb2478d4 31
021b8139 32=item L<Moose::Cookbook::Basics::Recipe2> - A simple B<BankAccount> example
471c4f09 33
f7f3648d 34A slightly more complex Moose class. Demonstrates using a method
35modifier in a subclass.
cb2478d4 36
021b8139 37=item L<Moose::Cookbook::Basics::Recipe3> - A lazy B<BinaryTree> example
471c4f09 38
f7f3648d 39Demonstrates several attribute features, including types, weak
0fde1850 40references, predicates ("does this object have a foo?"), defaults,
41laziness, and triggers.
cb2478d4 42
021b8139 43=item L<Moose::Cookbook::Basics::Recipe4> - Subtypes, and modeling a simple B<Company> class hierarchy
471c4f09 44
f7f3648d 45Introduces the creation and use of custom types, a C<BUILD> method,
46and the use of C<override> in a subclass.
cb2478d4 47
021b8139 48=item L<Moose::Cookbook::Basics::Recipe5> - More subtypes, coercion in a B<Request> class
471c4f09 49
f7f3648d 50More type examples, including the use of type coercions.
cb2478d4 51
021b8139 52=item L<Moose::Cookbook::Basics::Recipe6> - The augment/inner example
496b74ab 53
f7f3648d 54Demonstrates the use of C<augment> method modifiers, a way of turning
55the usual method overriding style "inside-out".
cb2478d4 56
021b8139 57=item L<Moose::Cookbook::Basics::Recipe7> - Making Moose fast with immutable
496b74ab 58
5de2944f 59Making a class immutable greatly increases the speed of accessors and
60object construction.
cb2478d4 61
021b8139 62=item L<Moose::Cookbook::Basics::Recipe8> - Managing complex relations with trigger (TODO)

67
021b8139 68=item L<Moose::Cookbook::Basics::Recipe9> - Builder methods and lazy_build
496b74ab 69
fbd7ad7a 70The builder feature provides an inheritable and role-composable way to
71provide a default attribute value.
cb2478d4 72
58d129ba 73=item L<Moose::Cookbook::Basics::Recipe10> - Operator overloading, subtypes, and coercion
c2a0627f 74
48757542 75Demonstrates using operator overloading, coercion, and subtypes to
a8b3fe62 76model how eye color is determined during reproduction.
c2a0627f 77
04d80e2a 78=item L<Moose::Cookbook::Basics::Recipe11> - Using BUILDARGS and BUILD to hook into object construction
45ef8386 79
04d80e2a 80This recipe demonstrates the use of C<BUILDARGS> and C<BUILD> to hook
81into object construction.

85=head2 Moose Roles
86
4eec354b 87These recipes will show you how to use Moose roles.
88
496b74ab 89=over 4
90
13dbfe49 91=item L<Moose::Cookbook::Roles::Recipe1> - The Moose::Role example
496b74ab 92
f7f3648d 93Demonstrates roles, which are also sometimes known as traits or
94mix-ins. Roles provide a method of code re-use which is orthogonal to
95subclassing.
cb2478d4 96
13dbfe49 97=item L<Moose::Cookbook::Roles::Recipe2> - Advanced Role Composition - method exclusion and aliasing
496b74ab 98
2e3d0a0a 99Sometimes you just want to include part of a role in your
100class. Sometimes you want the whole role but one if its methods
101conflicts with one in your class. With method exclusion and aliasing,
102you can work around these problems.
cb2478d4 103
9a823f26 104=item L<Moose::Cookbook::Roles::Recipe3> - Applying a role to an object instance
104379bc 105
9a823f26 106In this recipe, we apply a role to an existing object instance.

110=head2 Meta Moose
111
4eec354b 112These recipes show you how to write your own meta classes, which lets
113you extend the object system provide by Moose.
114
496b74ab 115=over 4
116
17a65b17 117=item L<Moose::Cookbook::Meta::Recipe1> - Welcome to the meta-world (Why Go Meta?)
496b74ab 118
38031ac8 119If you're wondering what all this "meta" stuff is, and why you should
120care about it, read this "recipe".
cb2478d4 121
43aa5bf9 122=item L<Moose::Cookbook::Meta::Recipe2> - A meta-attribute, attributes with labels
496b74ab 123
f7f3648d 124One way to extend Moose is to provide your own attribute
125metaclasses. Attribute metaclasses let you extend attribute
126declarations (with C<has>) and behavior to provide additional
127attribute functionality.
cb2478d4 128
43aa5bf9 129=item L<Moose::Cookbook::Meta::Recipe3> - Labels implemented via attribute traits
a7d0cd00 130
aff0421c 131Extending Moose's attribute metaclass is a great way to add
132functionality. However, attributes can only have one metaclass.
133Applying roles to the attribute metaclass lets you provide
134composable attribute functionality.
cb2478d4 135
3f002851 136=item L<Moose::Cookbook::Meta::Recipe4> - Adding a "table" attribute to the metaclass
137
138If you want to store more information about your classes, you'll have
139to extend C<Moose::Meta::Class>. Doing so is simple, but you'll
140probably also want to provide some sugar, so see
c5b9daec 141L<Moose::Cookbook::Extending::Recipe2> as well.
3f002851 142
c5b9daec 143=item L<Moose::Cookbook::Meta::Recipe5> - The "table" attribute implemented as a metaclass trait
24a8fe99 144
c5b9daec 145This example takes the class metaclass we saw in the previous recipe
146and reimplements it as a metaclass trait.
cb2478d4 147
1acd5999 148=item L<Moose::Cookbook::Meta::Recipe6> - Hooking into the immutabilization system (TODO)
149
150Moose 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
153object creation, attribute access, and so on.
154
155If you are creating your own metaclasses, you may need to hook into
156the immutabilization system. This cuts across a number of spots,
157including the metaclass class, meta method classes, and possibly the
158meta-instance class as well.
159
160This recipe shows you how to write extensions which immutabilize
161properly.

6fa0a13f 169=head2 Extending Moose
170
4eec354b 171These recipes cover some more ways to extend Moose, and will be useful
172if you plan to write your own C<MooseX> module.

c8d5f1e1 176=item L<Moose::Cookbook::Extending::Recipe1> - Moose extension overview
177
178There are quite a number of ways to extend Moose. This recipe explains
179provides an overview of each method, and provides recommendations for
180when each is appropriate.
181
f3ce0579 182=item L<Moose::Cookbook::Extending::Recipe2> - Providing a base object class role
c8d5f1e1 183
184Many base object class extensions can be implemented as roles. This
f3ce0579 185example shows how to provide a base object class debugging role that
186is applied to any class that uses a notional C<MooseX::Debugging>
187module.
c8d5f1e1 188
189=item L<Moose::Cookbook::Extending::Recipe3> - Providing an alternate base object class
6fa0a13f 190
191You may find that you want to provide an alternate base object class
192along with a meta extension, or maybe you just want to add some
193functionality to all your classes without typing C<extends
194'MyApp::Base'> over and over.
195
c8d5f1e1 196=item L<Moose::Cookbook::Extending::Recipe4> - Acting like Moose.pm and providing sugar Moose-style
6fa0a13f 197
c5b9daec 198This recipe shows how to provide a replacement for C<Moose.pm>. You
199may want to do this as part of the API for a C<MooseX> module,
5583dc1c 200especially if you want to default to a new metaclass class or base
201object class.
