MooseX::Attributes::Curried 0.03

MooseX::Attributes::Curried is a Perl module that lets you define curried versions of "has" in Moose. If many of your attributes share the same options, especially across multiple classes, then you can refactor those options away into a curried has.

Typical usage of this extension is to create a standalone "has library" module. If you only need a curried has for one class, then you might as well just define a sub has_datetime { has(...) } in that class.

When you use your "has library", you can customize each curried has further by specifying additional options on your import line, like so:

 use MyAttrs (
 has_datetime => {
 is => 'ro',
 },
 has_datetime => {
 -as => 'needs_datetime',
 required => 1,
 },
 );

Your "defaults" for the attribute can also be a code reference. This code reference will receive both the additional specializations performed when the curried attribute was imported, as well as any additional specializations used in the individual attribute. This is immensely powerful, see t/007-smart-has.t for a taste.

SYNOPSIS

 package MyAttrs;
 use MooseX::Attributes::Curried (
 has_datetime => {
 isa => 'DateTime',
 default => sub { DateTime->now },
 },
 has_rw => {
 is => 'rw',
 },
 );

 package My::Class;
 use Moose;
 use MyAttrs;

 has_datetime 'birthday' => (
 is => 'ro',
 );

 has_rw 'age' => (
 isa => 'Int',
 );
