• On Ubuntu, sudo apt-get install curl pkg-config libssl-dev clang
• On NixOS (using flakes):
  • Install direnv
  • Run echo use flake > .envrc
  • Run direnv allow in the repository root
  • Finally run make or make cli
• rustup
• Stable Rust, installed via rustup install stable && rustup default stable
• wasm32-wasip1, can be installed via rustup target add wasm32-wasip1
• wasm32-wasip2, can be installed via rustup target add wasm32-wasip2
• Rosetta 2 if running MacOS on Apple Silicon, can be installed via softwareupdate --install-rosetta

How to build

In the repository root, run:

$ cargo build -p javy-plugin --target=wasm32-wasip1 -r
$ cargo build -p javy-cli -r

Alternatively if you want to install the javy binary globally, at the repository root, run:

$ cargo build -p javy-plugin --target=wasm32-wasip1 -r
$ cargo install --path crates/cli

If you are going to recompile frequently, you may want to prepend CARGO_PROFILE_RELEASE_LTO=off to cargo build for the CLI to speed up the build.
