NAME Mo - Micro Objects. Mo is less. SYNOPSIS package Less; use Mo; extends 'Nothing'; has 'something' => ( is => 'rw', default => sub { my $self = shift; $self->build_something; }, ); sub BUILD { my $self = shift; $self->SUPER::BUILD(); # ... } DESCRIPTION use Mo. Mo is less. Moose led to Mouse led to Moo led to Mo. M is nothing. Mo is more. Not much. When Moo is more than you need, drop an 'o' and get some Mo. FEATURES This is what you get. Nothing Mo. "new" method Mo provides a "new" object constructor. It will call the "BUILD" method after creation if it "can". "extends" Mo exports the "extends" keyword, to name your parent class. "Mo" itself is your default parent class, of course. "has" Mo exports a "has" keyword, to generate accessors. These accessors support "get" and "set" operations and allows a "default". That's it. has 'name'; has 'name' => ( default => sub { 'Joe' } ); "has" takes arguments after the name. Here is what it currently supports: default Should be a code reference. The object instance is passed in, and it should return the default value for this attribute. Default is always called lazily. Any other arguments are ignored. This lets you switch from Moo to Mo and back, without having to change all your accessors. "strict" and "warnings" Mo turns on "use strict" and "use warnings". Embeddable Mo is tiny. You can easily inline it in your code, if you want to. AUTHORS Ingy döt Net Damien 'dams' Krotkine COPYRIGHT AND LICENSE Copyright (c) 2011. Ingy döt Net.
