NAME
MooseX::NewDefaults - Alter attribute defaults with less pain
VERSION
version 0.003
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;
# 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 certanly not the prettiest thing ever, either.
That's where we come in.
This package introduces new sugar that you can use in the baseclass, 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');
