NAME

Class::Tiny::Antlers - Moose-like sugar for Class::Tiny

SYNOPSIS

{
   package Point;
   use Class::Tiny::Antlers;
   has x => (is => 'ro');
   has y => (is => 'ro');
}

{
   package Point3D;
   use Class::Tiny::Antlers;
   extends 'Point';
   has z => (is => 'ro');
}

DESCRIPTION

Class::Tiny::Antlers provides Moose-like has, extends, with, before, after and around keywords for Class::Tiny. (The with keyword requires Role::Tiny; method modifiers require Class::Method::Modifiers.)

Class::Tiny doesn't support all Moose's attribute options; has should throw you an error if you try to do something it doesn't support (like triggers).

Class::Tiny::Antlers does however hack in support for is => 'ro' and Moo-style is => 'rwp', clearers and predicates.

From version 0.24, Class::Tiny::Antlers also adds support for `isa` and `coerce` using Type::Tiny. (I mean, this is a TOBYINK module, so what do you expect?!) Technically MooseX::Types, MouseX::Types, Specio, and Type::Nano should work, but these are less tested.

Export

By default, Class::Tiny::Antlers exports has, with and extends, and also imports strict into its caller. You can optionally also import confess and warnings:

use Class::Tiny::Antlers qw( -default confess warnings );

And Class::Method::Modifiers keywords:

use Class::Tiny::Antlers qw( -default before after around );
use Class::Tiny::Antlers qw( -default -cmm );  # same thing

If you just want everything:

use Class::Tiny::Antlers qw( -all );

Class::Tiny::Antlers also ensures that Class::Tiny's import method is called for your class.

You can put a no Class::Tiny::Antlers statement at the end of your class definition to wipe the imported functions out of your namespace. (This does not unimport strict/warnings though.) To clean up your namespace more thoroughly, use something like namespace::sweep.

Functions

has $attr, %spec

Create an attribute. The specification hash roughly supports is, default, clearer and predicate as per Moose and Moo.

extends @classes

Set the base class(es) for your class.

with @roles

Compose Role::Tiny roles with your class.

before $name, \&code

Install a before modifier using Class::Method::Modifiers.

after $name, \&code

Install a after modifier using Class::Method::Modifiers.

around $name, \&code

Install a around modifier using Class::Method::Modifiers.

confess $format, @list

sprintf-fueled version of Carp's confess.

Methods

Class::Tiny::Antlers inherits the get_all_attributes_for and get_all_attribute_defaults_for methods from Class::Tiny, and also provides:

Class::Tiny::Antlers->get_all_attribute_specs_for($class)

Gets Moose-style attribute specification hashes for all the class' attributes as a big hashref. (Includes inherited attributes.)
