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;
# enhance your object before it is returned by new()
}
DESCRIPTION
use Mo. Mo is less. Much less.
Moose is huge. 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 object creation, it will call the
BUILD
method (if present) for all of its parents and itself. extends
-
Mo exports the
extends
keyword, to declare your parent class.Mo
itself is your default parent class, of course.Mo only supports single inheritance. If you need multiple inheritance or roles, you should upgrade to Moo.
has
-
Mo exports a
has
keyword, to generate accessors.These accessors always support both
get
andset
operations. They allow thedefault
andbuilder
options. 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
andwarnings
-
Mo turns on
use strict
anduse warnings
for you. - Embeddable
-
Mo is tiny. It is compressed into a single line. You can easily inline it in your code, should you want to do that.
