Class::Tiny::Antlers(3pm)

Usage

   {
      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');
   }

Overview

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.)
