# 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**,

works like this because I need them or I find it enjoyable; however, don't let
that stop you if you feel like it ;)
