NAME

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

VERSION

       version 2.0604

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 Moose::Exporter we saw in Moose::Cookbook::Extending::ExtensionOverview and the class metaclass trait we
       saw in Moose::Cookbook::Meta::Table_MetaclassTrait. 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 Moose::Exporter 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 Fey::ORM for a more extensive example.

NAME

       Moose::Cookbook::Extending::Recipe4 - Acting like Moose.pm and providing sugar Moose-style

VERSION

       version 2.0205

SYNOPSIS

	 package MyApp::Mooseish;

	 use Moose ();
	 use Moose::Exporter;

	 Moose::Exporter->setup_import_methods(
	     with_meta => ['has_table'],
	     also      => 'Moose',
	 );

	 sub init_meta {
	     shift;
	     return Moose->init_meta( @_, metaclass => 'MyApp::Meta::Class' );
	 }

	 sub has_table {
	     my $meta = shift;
	     $meta->table(shift);
	 }

	 package MyApp::Meta::Class;
	 use Moose;

	 extends 'Moose::Meta::Class';

	 has 'table' => ( is => 'rw' );

DESCRIPTION

       This recipe expands on the use of Moose::Exporter we saw in Moose::Cookbook::Extending::Recipe1. Instead of providing our own object base
       class, we provide our own metaclass class, and we also export a "has_table" sugar function.

       Given the above code, you can now replace all instances of "use Moose" with "use MyApp::Mooseish". Similarly, "no Moose" is now replaced
       with "no MyApp::Mooseish".

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

       See the Moose::Exporter 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 MyApp::Mooseish;

	 has_table 'User';

	 has 'username' => ( is => 'ro' );
	 has 'password' => ( is => 'ro' );

	 sub login { ... }

	 no MyApp::Mooseish;

       All of the normal Moose sugar ("has()", "with()", etc) is available when you "use MyApp::Mooseish".

CONCLUSION

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