MooseX...Mooish(3pm)

💖 MooseX::Meta::TypeConstraint::Mooish 💖

okay so bestie, welcome to MooseX::Meta::TypeConstraint::Mooish, aka the little translator that takes your Moo-style constraints and makes them speak fluent Moose. it's a Perl module, it lives in User Contributed Perl Documentation, and it's about to change your whole has game. slay. 💅

---

✨ VERSION ✨

this doc is describing version 0.001 of MooseX::Meta::TypeConstraint::Mooish — it dropped March 12, 2015, as part of the MooseX-Meta-TypeConstraint-Mooish fam. vintage but iconic, no cap. 🎀

---

🌸 SYNOPSIS 🌸

easiest route? go through AttributeShortcuts. the way that it just works:

# easiest is via AttributeShortcuts
use MooseX::AttributeShortcuts 0.028;

has foo => (
    is  => 'rw',
    isa => sub { die unless $_[0] == 5 },
);

or, the hard way (respect, but it's giving extra steps):

# or, the hard way
use MooseX::Meta::TypeConstraint::Mooish;

has foo => (
    is  => 'rw',
    isa => MooseX::Meta::TypeConstraint::Mooish->new(
        constraint => sub { die unless $_[0] == 5 },
    ),
);

🦋 DESCRIPTION 🦋

so here's the tea, bestie. 🍵

Moose type constraints are expected to return true if the value passes the constraint, and false otherwise. Moo "constraints", on the other hand? they just straight-up die if validation fails. different philosophies, same energy, lowkey incompatible.

this metaclass allows for Moo-style constraints; it will wrap them and translate their Moo into a dialect Moose understands. it's literally a translator. 🌈

note that this is largely to enable functionality in MooseX::AttributeShortcuts; the easiest way use this metaclass is by using that package.

also — and this is the fun part — as it's not inconceivable that this functionality may be desired in other constraint metaclasses, the bulk of this metaclass' functionality is implemented as a trait. modular queen behavior. 👑
