rurust

A Rust wrapper over the MRI Ruby VM.

Documentation

Allows you to create a Ruby VM, eval code, plug classes, define modules, and insert C functions into the environment.

For a more high level library, take a look at plugger.

Examples

A simple REPL

extern fn callable_from_ruby() {
    println!("Hello World!");
}

fn main() {
    let mut vm = rurust::VM::new().unwrap();

    vm.class("Rust").
        method("hello_world", callable_from_ruby as *const _, 0).
        method("foo", callable_from_ruby as *const _, 0).
        build();

    loop {
        let mut line = String::new();
        std::io::stdin().read_line(&mut line).unwrap();

        let result = vm.eval(&line);
        println!("{:?}", result);
    }
}
