## Developing

### Set up

This is no different than other Rust projects.

```bash
git clone https://github.com/nushell/nushell
cd nushell
cargo build
```

### Useful Commands

- Build and run Nushell:

  ```shell
  cargo build --release && cargo run --release
  ```

- Build and run with extra features:
  ```shell
  cargo build --release --features=extra && cargo run --release --features=extra
  ```

- Run Clippy on Nushell:

  ```shell
  cargo clippy --all --features=stable
  ```

- Run all tests:

  ```shell
  cargo test --all --features=stable
  ```

- Run all tests for a specific command

  ```shell
  cargo test --package nu-cli --test main -- commands::<command_name_here>
  ```

- Check to see if there are code formatting issues

  ```shell
  cargo fmt --all -- --check
  ```

- Format the code in the project

  ```shell
  cargo fmt --all
  ```

### Debugging Tips

- To view verbose logs when developing, enable the `trace` log level.

  ```shell
  cargo build --release --features=extra && cargo run --release --features=extra -- --loglevel trace
  ```
