NAME

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

SYNOPSIS

  package MyApp::Types;
  use MooX::Types::MooseLike;
  use base qw(Exporter);
  our @EXPORT_OK = ();

  # Define some types
  my $defs = [{
    name => 'MyType',
    test => sub { predicate($_[0]) },
    message => sub { "$_[0] is not the type we want!" }
  },
  {
    name => 'VarChar',
    test => sub {
      my ($value, $param) = @_;
      length($value) <= $param;
    },
    message => sub { "$_[0] is too large! It should be less than or equal to $_[1]." }
  }];

  # Make the types available - this adds them to @EXPORT_OK automatically.
  MooX::Types::MooseLike::register_types($defs, __PACKAGE__);

  ...

  # Somewhere in code that uses the type
  package MyApp::Foo;
  use Moo;
  use MyApp::Types qw(MyType VarChar);

  has attribute => (
    is  => 'ro',
    isa => MyType,
  );

  has string => (
    is  => 'ro',
    isa => VarChar[25]
  );

DESCRIPTION

This module provides a possibility to build your own set of Moose-like types. These custom types can then be used to describe fields in Moo-based classes.

See MooX::Types::MooseLike::Base for a list of available base types. Its source also provides an example of how to build base types, along with both parameterizable and non-parameterizable.

SEE ALSO

MooX::Types::MooseLike::Numeric - an example of building subtypes.

MooX::Types::SetObject - an example of building parameterized types.

MooX::Types::MooseLike::Email, MooX::Types::MooseLike::DateTime

Type::Tiny - another implementation of type constraints. Compatible with Moo, Moose and Mouse.

FUNCTIONS

register_types

register_types( types, package, moose_namespace )

Install the given types within the package. This makes the types automatically exportable by adding them to @EXPORT_OK of the package. Types are expected to be an array ref where every type is of the following format:

  {
    name            => 'MyType',
    test            => sub { check_the_value_somehow($_[0]) },
    message         => sub { "$_[0] is not the type we want!" },
    parameterizable => sub { ... }, # Optional
    inflate         => sub { ... }, # Optional
  }

exception_message

exception_message( value, part_of_the_exception_string )

Helper function to be used in a type definition:

  {
    ...
    message => sub { return exception_message($_[0], 'a HashRef' },
    ...
  }

In the event of <value> mismatching the type constraints it produces the message:

  "<value> is not a HashRef!"

inflate_type

inflate_type( coderef )

Inflates the type to a Moose type. Requires Moose.
