# Experimental Moss interpreter in Rust

Experimental interpreter for the dynamic programming language Moss.
This implementation is written in Rust and more type safe than
the [first](https://github.com/JohnBSmith/moss-c) implementation in C.

See [Moss Home](https://johnbsmith.github.io/moss/home.htm).

Example of calling Moss code from Rust:

```rust
extern crate moss;

fn main(){
    let i = moss::Interpreter::new();
    let x = i.eval(r#"
        f = |n| 1 if n==0 else n*f(n-1)
        f(4)
    "#);
    println!("{}",x);
}
```
