Toy 0.6.0

This is the Toy programming language interpreter, written in C.

Special thanks to http://craftinginterpreters.com/ for their fantastic book that set me on this path.

Building

Simply run make in the root directory.

Syntax

import "standard"; //for a bunch of utility functions


print "Hello world"; //"print" is a keyword

var msg = "foobar"; //declare a variable like this

assert true, "This message won't be seen"; //assert is another keyword

//-------------------------

fn makeCounter() { //declare a function like this
	var total: int = 0; //declare a variable with a type like this

	fn counter(): int { //declare a return type like this
		return ++total;
	}

	return counter; //closures are explicitly supported
}

var counter = makeCounter();

print counter(); //1
print counter(); //2
print counter(); //3

export makeCounter; //export this variable to the host program
