NAME

6       MooX::Types::MooseLike - some Moosish types and a type builder

SYNOPSIS

9         package MyApp::Types;
10         use MooX::Types::MooseLike;
11         use base qw(Exporter);
12         our @EXPORT_OK = ();
13
14         # Define some types
15         my $defs = [{
16           name => 'MyType',
17           test => sub { predicate($_[0]) },
18           message => sub { "$_[0] is not the type we want!" }
19         },
20         {
21           name => 'VarChar',
22           test => sub {
23             my ($value, $param) = @_;
24             length($value) <= $param;
25           },
26           message => sub { "$_[0] is too large! It should be less than or equal to $_[1]." }
27         }];
28
29         # Make the types available - this adds them to @EXPORT_OK automatically.
30         MooX::Types::MooseLike::register_types($defs, __PACKAGE__);
31
32         ...
33
34         # Somewhere in code that uses the type
35         package MyApp::Foo;
36         use Moo;
37         use MyApp::Types qw(MyType VarChar);
38

40           is  => 'ro',
41           isa => MyType,
42         );
43
44         has string => (

DESCRIPTION

50       This module provides a possibility to build your own set of Moose-like
51       types. These custom types can then be used to describe fields in Moo-
52       based classes.
53
54       See MooX::Types::MooseLike::Base for a list of available base types.
55       Its source also provides an example of how to build base types, along
56       with both parameterizable and non-parameterizable.

FUNCTIONS

59   register_types
60       register_types( types, package, moose_namespace )
61
62       Install the given types within the package. This makes the types
63       automatically exportable by adding them to @EXPORT_OK of the package.
64       Types are expected to be an array ref where every type is of the
65       following format:
66
67         {
68           name            => 'MyType',
69           test            => sub { check_the_value_somehow($_[0]) },
70           message         => sub { "$_[0] is not the type we want!" },
71           subtype_of      => 'SomeParentType',           # Optional
72           from            => 'Some::Parent::CoolTypes',  # Optional
73           parameterizable => sub { ... },                # Optional
74           inflate         => sub { ... },                # Optional
75         }
76
77       A type can be declared with a reference (subtype_of) to some previously
78       declared type. In this case the new type will inherit the behaviour of
79       the referenced type.
80
81       The referenced type can come either from the same package or from a
82       third party package:
83
84         MooX::Types::MooseLike::register_types([{
85           name       => 'GreaterThan10',
86           subtype_of => 'Int',
87           from       => 'MooX::Types::MooseLike::Base',
88           test       => sub { $_[0] > 10 },
89           message    => sub { 'not greater than 10' },
90         }], __PACKAGE__);
91
92         MooX::Types::MooseLike::register_types([{
93           name       => 'Between10And20',
94           subtype_of => 'GreaterThan10',
95           from       => __PACKAGE__,
96           test       => sub { $_[0] < 20 },
97           message    => sub { 'not an integer between 10 and 20' },
98         }], __PACKAGE__);
99
100         MooX::Types::MooseLike::register_types([{
101           name       => 'Between10And30',
102           subtype_of => GreaterThan10(),
103           test       => sub { $_[0] < 30 },
104           message    => sub { 'not an integer between 10 and 30' },
105         }], __PACKAGE__);
106
107   exception_message
108       exception_message( value, part_of_the_exception_string )
109
110       Helper function to be used in a type definition:
111
112         {
113           ...
114           message => sub { return exception_message($_[0], 'a HashRef' },
115           ...
116         }
117
118       In the event of <value> mismatching the type constraints it produces
119       the message:
120
121         "<value> is not a HashRef!"
122
123   inflate_type
124       inflate_type( coderef )
125
126       Inflates the type to a Moose type. Requires Moose.
