Toy v2.x

The Toy Programming Language is an imperative, bytecode-interpreted, embeddable scripting language. Rather than functioning independently, it serves as part of another program, the "host". This design allows for straightforward customization by both the host's developers and end users, achieved by exposing program logic through external scripts.

This repository holds the reference implementation for Toy version 2.x, written in C - alpha testing is currently underway.

Nifty Features

Simple C-like syntax
Intermediate AST and bytecode representations
Strong, but optional type system
First-class functions and closures
Extensible with native C-bindings
Can re-direct output, error and assertion messages
Open-Source under the zlib license

Syntax

fn makeCounter() {
	var counter: Int = 0;

	fn increment() {
		return ++counter;
	}

	return increment;
}

var tally = makeCounter();

while (true) {
	var result = tally();

	print result; //prints 1 to 10

	if (result >= 10) {
		break;
	}
}

Building

This project requires gcc and make by default, but should also work in other environments. Officially supported platforms include linux, windows and macOS, see source/toy_common.h for implementation details.

Run make in the root directory to build the shared library named libToy.so and a useable REPL named repl.out.
