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. Much 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. You pass it a list of name/value pairs and it returns a new object.

After creation, it will call the BUILD method for all its parents and itself, if any of the classes have a BUILD method.

extends

Mo exports the extends keyword, to name your parent class. Mo itself is your default parent class, of course. You can have multiple parent classes.

has

Mo exports a has keyword, to generate accessors.

These accessors support get and set operations and allows a default. That's it.

has 'name1';
has 'name2' => ( default => sub { 'Joe' } );
has 'name3' => ( builder => 'name_builder' );

has takes arguments after the name. Here is what it currently supports:

default

Must 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. ie It is called when you try to get the value and it does not(exists()).

builder

Must be a method name. This method should return the default value for this attribute. builder 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 for you.

Embeddable

Mo is tiny. It is currently < 15 lines, < 80 chars each.

You could easily inline it in your code, if you wanted to.
