classic VS ulisp

Once they grasp some lua basics and I've actually got a little code running but before I do much to make a game. I'd suggest you give them loom my fork includes the documentation with the code. Also a class system either a basic but easy to understand or more featureful.

I can't criticism your implementation at the moment but I want to share a tiny class module for Lua as a inspiration. https://github.com/rxi/classic

(this example uses classic, which is a library I like using for OOP to keep things simple)

I like classic over middleclass: https://github.com/rxi/classic Feels lighter weight, like barely anything.

You can do oop in Lua too! You just need a class lib.

I'd recommend spending a bit of time with the readme for classic: https://github.com/rxi/classic

Get as simple as possible OOP library, for example this one and write some code using it. This library can inherit ordinary functions, but not any metamethods. Try to improve it. If you can implement metamethod chaining inheritance that allows you to __call an instance of inherited classes like a function, then you understand metamethods thoroughly. Even if you fail, it still will be a good practice.

I love his projects too. He's also the creator of uLisp.

Not CL, but there is ulisp (http://www.ulisp.com/) for microcontrollers, supposed to be really tiny, and there is Carp (https://github.com/carp-lang/Carp) which is without a GC so seems suitable for real-time stuff.

There's also ulisp (for Arduino projects etc.): http://www.ulisp.com/

This is larger, because there are functions for accessing peripherals, and the core is more standard lispy with 'caadr' et.al., and it has a compacting GC, so images can be saved as a compact blob.

You might consider uLisp, it's very Common Lispy for the memory constraints given (sans macros and splicing quote). And you can still connect to it and save an image. I've tried it and it works well enough. Here is the homepage.

Agreed - the interactivity is good. Lisp is close (have you seen http://www.ulisp.com/ - I can't believe they got into into that small a target!). Python is ok, but for some reason I don't use the REPL in the same way I do in Forth - I think calling functions is just harder somehow. Mostly is exploring valves from the Python REPL.
