=head1 NAME
Moose::Cookbook::Extending::Mooseish_MooseSugar - Acting like Moose.pm and providing sugar Moose-style
=head1 VERSION
version 2.1005
=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
