I haven’t any problem to comment it with you. After all it’s open source. w3s project is already released to the publi (http://sourceforge.net/projects/w3s/). Also I wrote a paper some months ago (http://searchlores.org/mhyst_w3s.htm).

As for the w3s language, now I’m writing an interface to access Java Objects from it. I’ll write some article about it as soon as I have something working.

Data types management sucks. I wanted for my language a loose types management. But as long as I need to instantiate java objects and pass arguments to it, I need a hard typed model.

If you’re really interested, I can send you the source code.

Thanks

I would love to share ideas with you, since neat and short implementation of (interpreted or not) languages is one of my hobbies.

There are mainly two reasons for the shortness of my implementation:

1. I decided to do it as a one-night stunt

2. The (static) closures and chains of environments in Lua are isomorphic to what is found in (most) LISP implementations; I used that isomorphism heavily.

Hope to see some code from you somewhere; please post an URL for anything you can expose to the big wide world

Thanks,

David

Hello,
I was creating a new language (lisp based) for my w3s personal web crawler, to serve as interpreter for user searching algorithms. The entire project is written in java. Then I discovered this post and I got shocked. Lol. Your code is really short!

I got some good ideas from your post.

Thank you!

Neat, and it ran straight out of the box. LuaLisp lacks a few primitives needed by my little Prolog in Lisp (dug up from a sibling directory to where resides groeb.pl), but adding them wouldn’t be a lot of work…
