Crate artichoke

Expand description

Artichoke Ruby

This crate is a Rust and Ruby implementation of the Ruby programming language. Artichoke is not production-ready, but intends to be a MRI-compliant implementation of Ruby 2.6.3.

This crate provides:

An embeddable Ruby interpreter, which can be created with the interpreter function.
A Rust and Ruby implementation of Ruby Core and Standard Library using high-quality Rust dependencies and modern Ruby.
Support for injecting Rust code and types into the interpreter with a rubygems-style File API.
The ability to disable parts of the interpreter VM or library functions at compile time. For example, deny access to the system environ by disabling the core-env-system feature.

Usage

You can create an interpreter and begin executing code on it:

use artichoke::prelude::*;

let mut interp = artichoke::interpreter()?;
let result = interp.eval(b"2 + 5")?;

Artichoke supports calling Ruby functions from Rust and converting between Ruby boxed values and Rust native types:

use artichoke::prelude::*;

let mut interp = artichoke::interpreter()?;
let s = interp.try_convert_mut("💎")?;
let codepoint = s.funcall(&mut interp, "ord", &[] /* args */, None /* block */)?;
let codepoint = codepoint.try_convert_into::<u32>(&interp)?;
assert_eq!(128142, codepoint);
