Introduction

A simple & naive conceptual-quasi-pseudo-primitive programming language.

Features

Full Object-oriented, i.e. cannot write pure function without a wrapper class
Dynamic, objects remembers their Class
Dynamic, can add methods and members to Classes at any time
message sending, like Objective-C

Why conceptual?

Currently no front-end (maybe never will)
No syntax (You can imagine one in your brain)

Why quasi?

Lives on C++
Can interact with C/C++ seamlessly

Why pseudo?

Come on, a language in less than 100 lines of implementation can not be considered as a serious language.

Why Primitive? (TODO)

Currently not provided, but someday will (if the whole repo not abandoned)

member access
standard library
- array
- primitive types, like int, bool etc
- string
multiple dispatch
malloc instead of new to be independent from C++

How To Write

Conceptual (remember, there is no syntax now):

	class Printer {
		(instancetype) print() {
			printf("hello world!, I am %s\n",typeof(this));
		}
	}

Code:

	#include "Runtime.h"
	Instance * print(RuntimeObject * receiver, std::vector<Instance *>args) {
	    printf("hello world!, I am %s\n",receiver->receiver->isa->name.c_str());
	    return receiver->receiver;
	}

	int main(int argc, const char * argv[]) {
	    Class *Printer = Class::createClass("Printer", nullptr);
	    Printer->appendMethod("print", print);
	    Instance *printer = Printer->newInstance();
	    printer->msg_send("print", std::vector<Instance*>());
	    return 0;
	}

Output:

	hello world!, I am Printer
