NAME MooX::NewDefaults - Alter attribute defaults with less pain VERSION version 0.001000 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'); AUTHORS * Kent Fredric <kentnl@cpan.org> * Chris Weyl <cweyl@alumni.drew.edu> COPYRIGHT AND LICENSE This software is Copyright (c) 2011 by Chris Weyl.
