Developing

Setup

Nushell requires a recent Rust toolchain and some dependencies; refer to the Nu Book for up-to-date requirements. After installing dependencies, you should be able to clone+build Nu like any other Rust project:

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

Useful Commands

Build and run Nushell:
```
cargo run
```
Build and run with extra features. Currently extra features include dataframes and sqlite database support.
```
cargo run --features=extra
```

Run Clippy on Nushell:

cargo clippy --workspace --features=extra -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect

Run all tests:

cargo test --workspace --features=extra

Run all tests for a specific command

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

Check to see if there are code formatting issues
```
cargo fmt --all -- --check
```
Format the code in the project
```
cargo fmt --all
```

Debugging Tips

To view verbose logs when developing, enable the trace log level.
```
cargo run --release --features=extra -- --log-level trace
```

To redirect trace logs to a file, enable the --log-target file switch.

cargo run --release --features=extra -- --log-level trace --log-target file
