NAME

MooX::late - easily translate Moose code to Moo

SYNOPSIS

package Foo;
use MooX 'late';
has bar => (is => 'ro', isa => 'Str');

or, without MooX:

package Foo;
use Moo;
use MooX::late;
has bar => (is => 'ro', isa => 'Str');

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:

  1. 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.

  2. Allows default => $non_reference_value to work when defining attributes.

  3. Allows lazy_build => 1 to work when defining attributes.

  4. Exports blessed and confess 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.

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. This is an optional dependency, but without it most type constraints are ignored.

The following modules bring additional Moose functionality to Moo:

If you have MooX then you can import them all at once using:

use MooX qw( late Override Augment );
