optional type restrictions for Moo attributes

NAME

MooX::Should - optional type restrictions for Moo attributes

VERSION

version v0.1.4

SYNOPSIS

use Moo;

use MooX::Should;
use Types::Standard -types;

has thing => (
  is     => 'ro',
  should => Int,
);

DESCRIPTION

This module is basically a shortcut for

use Devel::StrictMode;
use PerlX::Maybe;

has thing => (
        is  => 'ro',
  maybe isa => STRICT ? Int : undef,
);

It allows you to completely ignore any type restrictions on Moo attributes at runtime, or to selectively enable them.

Note that you can specify a (weaker) type restriction for an attribute:

use Types::Common::Numeric qw/ PositiveInt /;
use Types::Standard qw/ Int /;

has thing => (
  is     => 'ro',
  isa    => Int,
  should => PositiveInt,
);

but this is equivalent to

use Devel::StrictMode;

has thing => (
  is     => 'ro',
  isa    => STRICT ? PositiveInt : Int,
);

• Devel::StrictMode
