package Moose::Cookbook::Extending::Mooseish_MooseSugar; # ABSTRACT: Acting like Moose.pm and providing sugar Moose-style =pod =head1 NAME Moose::Cookbook::Extending::Mooseish_MooseSugar - Acting like Moose.pm and providing sugar Moose-style =head1 VERSION version 2.0604 =head1 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', ); =head1 DESCRIPTION This recipe expands on the use of L<Moose::Exporter> we saw in L<Moose::Cookbook::Extending::ExtensionOverview> and the class metaclass trait we saw in L<Moose::Cookbook::Meta::Table_MetaclassTrait>. In this example we provide our own metaclass trait, and we also export a C<has_table> sugar function. The C<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 C<S<my $meta = shift;>>. See the L<Moose::Exporter> docs for more details on its API. =head1 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 { ... } =head1 CONCLUSION Providing sugar functions can make your extension look much more Moose-ish. See L<Fey::ORM> for a more extensive example. =begin testing { package MyApp::User; use Moose; MyApp::Mooseish->import; has_table( 'User' ); has( 'username' => ( is => 'ro' ) ); has( 'password' => ( is => 'ro' ) ); sub login { } } can_ok( MyApp::User->meta, 'table' ); is( MyApp::User->meta->table, 'User', 'MyApp::User->meta->table returns User' ); ok( MyApp::User->can('username'), 'MyApp::User has username method' ); =end testing =head1 AUTHOR Moose is maintained by the Moose Cabal, along with the help of many contributors.
