Hi, what is this project?

[h8liu]

Just curious, what is zin? What do you have in your mind?

Zin is a programming language. I design it to try some interesting ideas.

It is yet under designing (not runable now).

Maybe...

• A homoiconic & functional (not pure) programming language. AST is regarded as data.
• Runtime = call stack + search path (dynamic namespace)
• CPS. Call by passing AST.
• No "real" core language (besides GC). The language (includes syntax and type system) is wrapped in the standard library and can be overrided / modified by the users.
• Nyfix syntax. It will be something like: definition(qsort) := ifx(length(param) > 0, ( qsort(param select '(param < head)) append qsort(param select '(param >= head)) ) with (head := param(0)), list())
• No optimization for speed. Glue of C code.

Thanks for your quick response. Please tolerate my curiosity; I have more questions:

• Is it going to be interpreted or compiled? Sounds more like a interpreted language.
• Also, it sounds like Scheme, so far. So what will be the difference?
• Sorry for my ignorance, what does "nyfix syntax" mean?

btw, I also speak Mandarin, if you prefer.

Is it going to be interpreted or compiled? Sounds more like a interpreted language.

Yes, it is interpreted. Partly JIT compiled is possible, but it takes a lot of work, you know. :)

Also, it sounds like Scheme, so far. So what will be the difference?

Most of the language (intepreter) is in the standard library. For example, True and False are defined atom.zc, and it is possible to redefine them (a := definition(true); definition(true) := '(print "ahaha", a)).

Another difference is that both variables and (some of) functions has "(on)write" operation. Function can run back. sin(x) := 1 will be an arcsine.

Besides, it will not be so "pure" but looks like a procedural programming language.

Sorry for my ignorance, what does "nyfix syntax" mean?

"中缀表达式" maybe :)

Thanks! :)
