Toy v2-beta

The Toy Scripting 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, written in C - open beta 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;
}

//'tally' holds internal state
var tally = makeCounter();

for (var result = 0; result < 10; result = tally()) {
	print result;
}

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.

Documentation

The contents of docs/ is also available on the official website toylang.com.
