Poop (Php's Object Oriented Project) is an experiment for classless object oriented programming.

It is highly inspired of javascript and python and also IO.

How to use

Create an instance

You create an instance by cloning another one, like the Object instance

include "src/lib.php";
$Range = Instance::object()->clone();

Making this will allow range to inherit form all of Object's attributes.

Add attributes and methods

Then you can add attributes and methods like this. Like in python, a method's first agrument must reference the instance itself so there is no more this keyword.

$Range->max = 10;
$Range->min = 0;
$Range->include = function($self, $value)
{
  return ($self->max > $value) && ($self->min <= $value);
};

In fact, min, max and include are not really attributes of the instance but stored inside an attribute named slots that contains an array of every attribute of the instance.

So getting a value or calling a method is in fact done using ghost methods and attributes with the special methods __get and __call. This make possible to search not only in the instance's slots but also in the slots on its prototype in chain until there is not more parent instance, which allow for inheritance.

Generating instances

Making one range is fine, but it can be more efficient to use inheritance to generate different ranges.

$Range->make = function($self, $min, $max)
{
  $new = $self->clone();
  $new->min = $min;
  $new->max = $max;
  return $new;
};

With $Range->make we can now create new ranges with the same behaviour as $Range.
