NAME

MooX::NewDefaults - Alter attribute defaults with less pain

VERSION

version 0.001002

SYNOPSIS

Concept and documentation liberally stolen from MooseX::NewDefaults

    package One;
    use Moo;

    has A => (is => 'ro', default => sub { 'say ahhh' });
    has B => (is => 'ro', default => sub { 'say whoo' });

    package Two;
    use Moo;
    use MooX::NewDefaults;

    extends 'One';

    # sugar for defining a new default
    default_for A => sub { 'say oooh' };

    # this is also legal
    default_for B => 'say oooh';

DESCRIPTION

Ever start using a package from the CPAN, only to discover that it requires lots of subclassing and has '+foo' => (default => ...)? It's not recommended Moose best practice, and it's certainly not the prettiest thing ever, either.

That's where we come in.

This package introduces new sugar that you can use in your class, default_for (as seen above).

e.g.

    has '+foo' => (default => sub { 'a b c' });

...is the same as:

    default_for foo => sub { 'a b c' };

NEW SUGAR

default_for

default_for() is a shortcut to extend an attribute to give it a new default; this default value may be any legal value for default options.

    # attribute bar defined elsewhere (e.g. superclass)
    default_for bar => 'new default';

... is the same as:

    has '+bar' => (default => 'new default');
