Mo - Micro Objects. Mo is less.
package Less;
use Mo;
extends 'Nothing';
has something => ();
sub BUILD {
my $self = shift;
# enhance your object before it is returned by new()
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.
To get just a little Mo from Mo, use "Mo Features" below.
Core 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.
Mo exports the "extends" keyword, to declare your parent class.
"Mo::Object" itself is your default parent class.
Mo only supports single inheritance. If you need multiple
inheritance or roles, you should upgrade to Moo.
Mo exports a "has" keyword, to generate accessors.
These accessors always support both "get" and "set" operations.
That's it.
has name => ();
has thing => (is => 'ro'); # arguments silently ignored
All arguments passed to "has" are ignored. This makes it easier to
switch between Mo and Moo, without having to change all your
"strict" and "warnings"
Mo turns on "use strict" and "use warnings" for you.
Mo is tiny. It is compressed into a single line. You can easily
inline it in your code, should you want to do that. See Mo::Inlining
for more information.
Mo Features
Mo is the bare minimum needed for Perl OO. Many times you'll want just a
couple more features. Don't worry. Mo's got you covered:
use Mo qw'default builder';
has name1 => ( default => sub { 'Joe' } );
has name2 => ( builder => 'name_builder' );
Mo simply loads the feature classes Mo::default and Mo::builder. These
add their magics to "has". A Mo::Feature module can enhance "new",
"extends" and "has", and also add new export subs, or remove existing
ones. See Mo::Features for a list of all the features and for an
explanation of the Feature API..
