ParenScriptObjectSystem

The ParenScript Object System (PSOS) is a facility for object-oriented programming in ParenScript using the same style and techniques as the CommonLispObjectSystem?. It consists of a set of macros in lisp and a runtime environment in Parenscript.

The current source may be downloaded via SVN:

Features

Multiple inheritance, generic functions, and basic method combination is currently implemented. Example Parenscript that uses PSOS:

    (defclass person ())
    (defclass politician (person))

    (defgeneric discuss-environment (individual))
    (defmethod discuss-environment ((individual person))
        (alert "I don't know anything about the environment"))
    (defmethod discuss-enviornment ((individual politician))
        (alert "The environment is an important issue, but so is Osama Bin Laden"))

TODO

* method dispatch optimization * slots beyond javascript's built-in per-object slot storage. * a well-defined metaobject protocol
