Building Artichoke

To build Artichoke, install the prerequisites and run:

$ git clone https://github.com/artichoke/artichoke.git
$ cd ./artichoke
$ cargo run --bin artichoke -- --version
$ cargo run --bin airb

WebAssembly

Artichoke can be used in WebAssembly environments via the wasm32-unknown-emscripten target. This target is not tested in CI and should be considered unstable.

rustup target add wasm32-unknown-emscripten
cargo build --release --target wasm32-unknown-unknown

This on its own does not produce a usable artifact. To build a WebAssembly bundle, depend on artichoke in a crate with a main. See the artichoke/playground repository for an example.

Prerequisites

Rust Toolchain

Artichoke is a collection of Rust crates and requires a Rust compiler. The specific version of Rust Artichoke requires is specified in the toolchain file.

Artichoke only guarantees support for the latest stable version of the Rust compiler.

Installation

The recommended way to install the Rust toolchain is with rustup. On macOS, you can install rustup with Homebrew:

brew install rustup-init
rustup-init

On Windows, you can install rustup from the official site and follow the prompts: https://win.rustup.rs/. This will automatically install Visual Studio (the Community Edition) and several C++ packages selected through the VS component installer.

Once rustup is installed, ensure the correct toolchain is present by running:

rustup install

It is recommended to install rustfmt and clippy to help with static code analysis and to do relevant checks prior to submitting PRs.

rustup component add rustfmt clippy

Bindgen

Artichoke generates Rust declarations for C code at build time using bindgen. bindgen is a build dependency of artichoke-backend and the bindgen CLI is not required to be present on $PATH.

Bindgen requires a libclang shared object to be discoverable. On macOS, no steps are necessary, but you may wish to install the lates LLVM, which you can do with Homebrew:

brew install llvm

On Windows, install LLVM from winget:

winget install --id=LLVM.LLVM -e

Rust Crates

Artichoke depends on several Rust libraries, or crates. Once you have the Rust toolchain installed, you can install the crates specified in Cargo.lock by running:

cargo build --workspace

C Toolchain

Some artichoke dependencies, like the mruby sys FFI bindings and the onig crate, build C static libraries and require a C compiler.

Artichoke specifically requires clang. WebAssembly targets require clang-8 or newer.

On Windows, install the latest LLVM distribution from GitHub and add LLVM to your PATH: https://github.com/llvm/llvm-project/releases.

cc Crate

Artichoke and some of its dependencies use the Rust cc crate to build. cc uses a platform-dependent C compiler to compile C sources. On Unix, cc crate uses the cc binary.

mruby Bindings

To build the Artichoke mruby backend, you will need a C compiler toolchain. By default, mruby requires the following to compile:

  • clang
  • ar

You can override the requirement for clang by setting the CC and LD environment variables.
