NAME

Type::Libraries - bundle up multiple type constraint libraries

SYNOPSIS

package Contact {
   use Moo;
   use MooX::late;
   
   use Type::Libraries [qw(
      Types::Standard
      MooseX::Types::Common::Numeric
      MouseX::Types::URI
   )], qw( ArrayRef NegativeInt PositiveInt Uri );
   
   has house_number => (
      is     => 'ro',
      isa    => PositiveInt->plus_coercions(NegativeInt, '-$_'),
      coerce => 1,
   );
   
   has websites => (
      is     => 'ro',
      isa    => ArrayRef[Uri],
      coerce => 1,
   );
}

DESCRIPTION

Type::Libraries allows you to import type constraints from multiple type constraint libraries in a single use statement.

Whatsmore, it wraps type constraints using Type::Tiny to ensure that the imported type constraint keywords will work in Moose-, Moo-, and Mouse-based classes and roles. Yes, that's right: you can use MooseX::Types libraries in Moo; MouseX::Types libraries in Moose and so on.

Using Type::Libraries in classes and roles

The example in the "SYNOPSIS" demonstrates how to use Type::Libraries in your class or role. (The example uses the MooX::late extension for Moo to enable coerce => 1 to work. Without this extension, Moo coercions need to be a coderef, but it by no means necessary to use MooX::late if you're using Type::Libraries.)

The basic syntax for importing types is:

use Type::Libraries \@libraries, @types;

For further information, see:

Using Type::Libraries to create a union type library

You can also use Type::Libraries to create your own type constraint library which is the union of several pre-existing one:

package MyTypes {
   use Type::Libraries;
   Type::Libraries->setup_class(
      __PACKAGE__,   # me
      qw(
         Types::Standard
         MooseX::Types::Common::Numeric
         MouseX::Types::URI
      ),
   );
}

Your union type library can then be imported from:

use MyTypes qw( ArrayRef NegativeInt PositiveInt Uri );

MooseX::Types::Combine is similar, but only supports MooseX::Types libraries.
