# ~~Helix~~



> :warning: **Deprecated** :warning:

>

> Sadly, we have made the decision to deprecate this project. While we had

> hoped to bootstrap the project to a point where it could flourish as a

> community project, unfortunately we ran into a number of roadblocks along the

> way, along with the need for significant architectural overhaul. While these

> issues are solvable on a technical level, doing so correctly requires more

> resources than we have been able to provide and progress has stalled.

>

> One of our goals was also to integrate our own Skylight agent with Helix,

> aligning the company's priorities with the project. While the Skylight agent

> is still written in Rust with a thin layer of C bindings (which is the part

> Helix would replace), we were not able to get the project to the point where

> we felt comfortable running it on our customer's servers. We did not identify

> any specific blockers that would prevent us from doing this, but ultimate, we

> did not have the necessary time and resources to realize this.

>

> Since we are a small team, it is unlikely that we will be able to provide the

> necessary investment in the foreseeable future to achieve our ambitions for

> the project. At this point, we believe it is in everyone's best interest to

> formally deprecate the project, accurately reflecting its effective state.

> Meanwhile, others in the Ruby and Rust communities have continued to explore

> in the adjacent research areas. Some of them have made great progress and

> brought new ideas and innovations to the table. We look forward to seeing

> these new ideas come to fruition and fill the void we are leaving.



Helix allows you to write Ruby classes in Rust without having to write the glue code yourself.



```rust

ruby! {

    class Console {

        def log(string: String) {

            println!("LOG: {}", string);

        }

    }

}

```



```shell

$ rake build

$ bundle exec irb

>> require "console"

>> Console.log("I'm in your Rust")

LOG: I'm in your Rust

 => nil

```

## Contributing



If you'd like to experiment with Helix, you can start with some of the examples in this repository.



Clone and download the Helix repository:

```shell

$ git clone https://github.com/tildeio/helix

$ cd helix

```



Navigate to the console example folder and bundle your `Gemfile`:

```shell

$ cd examples/console

$ bundle install

```



Run `rake irb` to build and start irb:

```shell

$ bundle exec rake irb

```



Try running some of the methods defined in `examples/console/src/lib.rs`:

```shell

> c = Console.new

Console { helix: VALUE(0x7fdacc19a6a0) }

 =>

> c.hello

hello

 => nil

> c.loglog('hello', 'world')

hello world

 => nil

```
