NAME
MooX::late - easily translate Moose code to Moo
SYNOPSIS
package Foo;
use Moo;
use MooX::late;
has bar => (is => "ro", isa => "Str", default => "MacLaren's Pub");
(Examples for Moo roles in section below.)
DESCRIPTION
Moo is a light-weight object oriented programming framework which aims to be compatible with Moose. It does this by detecting when Moose has been loaded, and automatically "inflating" its classes and roles to full Moose classes and roles. This way, Moo classes can consume Moose roles, Moose classes can extend Moo classes, and so forth.
However, the surface syntax of Moo differs somewhat from Moose. For example the isa
option when defining attributes in Moose must be either a string or a blessed Moose::Meta::TypeConstraint object; but in Moo must be a coderef. These differences in surface syntax make porting code from Moose to Moo potentially tricky. MooX::late provides some assistance by enabling a slightly more Moosey surface syntax.
MooX::late does the following:
Allows
isa => $string
to work when defining attributes for all Moose's built-in type constraints (and assumes other strings are package names).This feature require MooX::Types::MooseLike::Base. If you don't have it, you'll get a warning message and all your
isa
checks will be no-ops.Allows
default => $non_reference_value
to work when defining attributes.Allows
lazy_build => 1
to work when defining attributes.Exports
blessed
andconfess
functions to your namespace.
Four features. It is not the aim of MooX::late
to make every aspect of Moo behave exactly identically to Moose. It's just going after the low-hanging fruit. So it does four things right now, and I promise that future versions will never do more than seven.
Use in Moo::Roles
MooX::late should work in Moo::Roles, with no particular caveats.
package MyRole;
use Moo::Role;
use MooX::late;
Package::Variant can be used to build the Moo equivalent of parameterized roles. MooX::late should work in roles built with Package::Variant.
use Package::Variant
importing => ['MooX::Role' => ['late']],
subs => [ qw(has with) ];
BUGS
Please report any bugs to http://rt.cpan.org/Dist/Display.html?Queue=MooX-late.
SEE ALSO
MooX::late
uses MooX::Types::MooseLike::Base to check many type constraints.
The following modules bring additional Moose functionality to Moo:
MooX::Override - support override/super
MooX::Augment - support augment/inner
MooX::HandlesVia is also in development, and once released MooX::late may be able to use it to add a native-traits-like feature.
MooX allows you to load Moo plus multiple MooX extension modules in a single line.
