Introduction

So-o defines a functional layer which adds an object-oriented programming model to a structured programming language. Inspired by Smalltalk, So-o is complete, simple and light, easy to understand.

Implementation

So-o proposes a standard implementation in several languages. The code in PHP is less than a 1000 lines.

Example
namespace Hello;

require_once 'So-o.php';

defclass('Hello', null, 1, null, null, null, array('hello'));

function i_hello($self) {
    echo 'Hello from So-o!', PHP_EOL;

    return $self;
}
$ php -a
php > require_once 'Hello.php';
php > $hello=sendmsg($Hello, 'new');
php > sendmsg($hello, 'hello');
Hello from So-o!
