NAME

MooseX::NewDefaults - Alter attribute defaults with less pain

VERSION

This document describes version 0.005 of MooseX::NewDefaults - released April 24, 2015 as part of MooseX-NewDefaults.

SYNOPSIS

package One;
use Moose;
use namespace::autoclean;

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

package Two;
use Moose;
use namespace::autoclean;
use MooseX::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');

Please note I do not expect to be gittip'ed or flattr'ed for this work, rather it is simply a very pleasant surprise. I largely create and release works like this because I need them or I find it enjoyable; however, don't let that stop you if you feel like it ;)

Flattr this, gittip me, or indulge my Amazon Wishlist... If you so desire.
