"A meta-level architecture for describing a wide range of object behaviour models. CodA can be thought of as a generic object engine framework in wich users define, on a per-object or even per-user basis, how object's behave computationally." This is an implementation of the CodA framework described in Jeff McAffer paper "Meta Level Programming With CodA". It is composed by two parts: * An Interpreter who dispatches messages to be interpreted to CodA * The CodA model for dispatching messages and building object behaviour models Actually the development is being done in Squeak 2.7, because the Interpreter Simulator runs fast as those images are small. In the future, the idea is to integrate CodA to the Pharo project.
