NAME

Moose::Cookbook::Extending::Mooseish_MooseSugar - Acting like Moose.pm and providing sugar Moose-style


VERSION

version 2.1605


SYNOPSIS

  package MyApp::Mooseish;
  use Moose::Exporter;
  Moose::Exporter->setup_import_methods(
      with_meta       => ['has_table'],
      class_metaroles => {
          class => ['MyApp::Meta::Class::Trait::HasTable'],
      },
  );
  sub has_table {
      my $meta = shift;
      $meta->table(shift);
  }
  package MyApp::Meta::Class::Trait::HasTable;
  use Moose::Role;
  has table => (
      is  => 'rw',
      isa => 'Str',
  );


DESCRIPTION

This recipe expands on the use of the Moose::Exporter manpage we saw in the Moose::Cookbook::Extending::ExtensionOverview manpage and the class metaclass trait we saw in the Moose::Cookbook::Meta::Table_MetaclassTrait manpage. In this example we provide our own metaclass trait, and we also export a has_table sugar function.

The with_meta parameter specifies a list of functions that should be wrapped before exporting. The wrapper simply ensures that the importing package's appropriate metaclass object is the first argument to the function, so we can do my $meta = shift;.

See the the Moose::Exporter manpage docs for more details on its API.


USING MyApp::Mooseish

The purpose of all this code is to provide a Moose-like interface. Here's what it would look like in actual use:

  package MyApp::User;
  use namespace::autoclean;
  use Moose;
  use MyApp::Mooseish;
  has_table 'User';
  has 'username' => ( is => 'ro' );
  has 'password' => ( is => 'ro' );
  sub login { ... }


CONCLUSION

Providing sugar functions can make your extension look much more Moose-ish. See the Fey::ORM manpage for a more extensive example.
