# 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.

## Nifty Features

* Simple C-like syntax
* Bytecode intermediate compilation
* `import` and `export` variables from the host program
* Optional, but robust type system
* functions and types are first-class citizens
* Fancy slice notation for strings, arrays and dictionaries (`print greeting[0:4:-1]; //prints "olleh"`)

## Building

For windows, simply run `make` in the root directory.

For linux, run `make repl-static` in the root directory (see [this issue for details](https://github.com/Ratstail91/Toy/issues/26)).

For mac, good luck.

## 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 tally = makeCounter();

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

export tally; //export this variable to the host program
```
