Ferrugo is a JVM implementation written in Rust.

*This is now just a **toy** project (for me/you to learn how it works).*

# Current Status

- Able to run some classfiles. see ``./examples/(Hello|BigInt|SmallPT).class``

- Partly support for JIT compiling powered by LLVM

- Aiming readable code (this is the hardest, yes)

# Building from Source

## Building on Linux

1. Install Rust

  Run the command below and follow the onscreen instructions. 

```sh

curl https://sh.rustup.rs -sSf | sh

```

2. Use Rust Nightly

```sh

rustup override set nightly

```

3. Install dependencies

  - LLVM 6.0

  - (Other packages as necessary...)

```sh

# e.g. Ubuntu or Debian

apt-get install llvm-6.0

```

4. Test 

```sh

cargo test

```

5. Build and Run

```sh

cargo run --release examples/Hello.class

```

## Building on other platforms

I don't know. Maybe almost the same as Linux.
