# Installation
## Clone Repo
```bash
git clone --recurse-submodules git@github.com:web-infra-dev/oxc.git
```
The `--recurse-submodules` flag will install the following submodules:
- [babel](https://github.com/babel/babel) registered for path `tasks/coverage/babel`
- [test262](https://github.com/tc39/test262) registered for path `tasks/coverage/test262`
- [typescript](https://github.com/microsoft/TypeScript) registered for path `tasks/coverage/typescript`
## New to Rust
### Install Rust
```bash
# https://rustup.rs/
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```
```bash
# move to the cloned repository
cd oxc
```
```bash
# rust toolchain
rustup show
```
`rustup show` reads the `./rust-toolchain.toml` file and installs the correct Rust toolchain and components for this project.
### Cargo Tools
Some additional Cargo tools are required for developing this project, they can be installed via [`cargo binstall`](https://github.com/cargo-bins/cargo-binstall). `cargo binstall` provides a low-complexity mechanism for installing rust binaries as an alternative to building from source via the slower `cargo install`.
You can download the [pre-compiled binary](https://github.com/cargo-bins/cargo-binstall#installation) and save it in `~/.cargo/bin` or install it by running `cargo install cargo-binstall`
## Required tools
```bash
cargo binstall just -y
```
[`just`](https://github.com/casey/just) is a handy way to save and run project-specific commands.
To initialize all the required tools, run
```
just init
```
## Commands
Run `just` for the list of available commands.
Run `just r` (alias for `just ready`) to make sure the whole project builds and runs correctly.
Take a look at `just new-rule` if you need to start porting a new ESLint rule.
Make sure the rule is registered in `crates/oxc_linter/src/rules.rs`.
