MooseX:...tribute(3)
πΈ NAME πΈ
okay bestie, welcome to the MooseX:...tribute(3) page from User Contributed Perl Documentation π this one is all about MooseX::ClassAttribute β it declares class attributes Moose-style, and honestly? iconic. β¨
β VERSION β
version 0.29 β periodt. π
π¦ SYNOPSIS π¦
package My::Class;
use Moose;
use MooseX::ClassAttribute;
class_has 'Cache' =>
( is => 'rw',
isa => 'HashRef',
default => sub { {} },
);
__PACKAGE__->meta()->make_immutable();
no Moose;
no MooseX::ClassAttribute;
# then later ...
My::Class->Cache()->{thing} = ...;
π DESCRIPTION π
This module lets you declare class attributes in exactly the same way as object attributes, using class_has() instead of has(). no cap, that's the whole vibe. π«Ά
You can use any feature of Moose's attribute declarations, including overriding a parent's attributes, delegation (handles), attribute traits, etc. All features should just work. The one exception? The required flag is not allowed for class attributes. π
The accessor methods for class attribute may be called on the class directly, or on objects of that class. Passing a class attribute to the constructor will not set that attribute. that's just how it is, bestie. π
β¨ FUNCTIONS β¨
This class exports one function when you use it: class_has(). It works exactly like Moose's has(), but it declares class attributes. slay. π
One little nit is that if you include no Moose in your class, you won't remove the class_has() function. To do that you must include no MooseX::ClassAttribute as well. Or you can just use namespace::autoclean instead. iykyk. π
π οΈ Implementation and Immutability π οΈ
This module will add a role to your class's metaclass β see MooseX::ClassAttribute::Trait::Class for details. This role provides introspection methods for class attributes. π
Class attributes themselves do the MooseX::ClassAttribute::Trait::Attribute role. yes bestie, they have a role too. π
π€ Cooperation with Metaclasses and Traits π€
This module should work with most attribute metaclasses and traits, but it's possible that conflicts could occur. This module has been tested to work with Moose's native traits. ngl, that's pretty reassuring. π
π§ Class Attributes in Roles π§
You can add a class attribute to a role. When that role is applied to a class, the class will have the relevant class attributes added. Note that attribute defaults will be calculated when the class attribute is composed into the class. β¨

πΈ DONATIONS πΈ
If you'd like to thank me for the work I've done on this module, please consider making a "donation" to me via PayPal. I spend a lot of free time creating free software, and would appreciate any support you'd care to offer. π₯Ίπ
Please note that I am not suggesting that you must do this in order for me to continue working on this particular software. I will continue to do so, inasmuch as I have in the past, for as long as it interests me. fr fr.
Similarly, a donation made in this way will probably not make me work on this software much more, unless I get so many donations that I can consider working on free software full time (let's all have a chuckle at that together). π
