Hum, from what I see on this, pdlua uses one method of "object encapsulation", while pdluax uses this single method type of object.
I know that Lua itself doesn't have an object style, I am just curious how pdlua does this, so that I can at least follow along in the style being used.
I really like what I have seen with pdlua, and you are right, Frank, I also think this will help to open up PD. One of the things that I have had trouble with in PD (by itself) was having to go in and repatch things to make some sort of change in how I am generating the data, while using pdlua, I think that it will make these sorts of changes much easier to understand.

The object system in pdlua isn't particularly well-thought out or elegant, I'd be interested in what you had developed and how it differs - maybe I could learn something from it.
Well, thanks for that vote of encouragement, but after studying the methods used in pdlua, it is actually a bit less verbose. Many of the things I had done my way were about a 1/3 longer. It was a method that I borrowed from a book I have.
Actually Lua itself doesn't have a preconfigured object system like C++ or Python, so you'd have to roll your own anyway. Pdlua uses a protype-based objects system.
Another interesting "object system" would be the Single Method approach: http://www.lua.org/pil/16.5.html where you use a closure to store the object's state.
I recently wrote a LOGO-style turtle using this idiom. Attached is a simplified version of it (removed typechecks etc).
Take special note of how seamlessly the single method turtle in smtut.lua can be included in the Pd object runturtle.lua using this primitive method:
function M:in_1(action, atoms) self.t(action, atoms) -- selt.t is the single method turtle endIt's even possible to convert smtut.lua to a proper module so that you can reload it luax-style while Pd is running.
