# Contributing to spytial

Contributions are welcome via pull requests. Bug reports, feature requests,
and questions are also welcome on the issue tracker.

## Local setup

```sh
cargo build
cargo test --lib --tests
cargo test --doc
```

## Running examples

```sh
cargo run --example rbt
```

Examples may open a browser window by default. To run headless (e.g. in CI),
set `SPYTIAL_NO_OPEN=1`:

```sh
SPYTIAL_NO_OPEN=1 cargo run --example rbt
```

## Code style

- `cargo fmt` clean (rustfmt with the repo's default config).
- `cargo clippy --all-targets -- -D warnings` clean.

## Pull requests

- Add an entry to the `Unreleased` section of [CHANGELOG.md]./CHANGELOG.md.
- Changes to decorators must include test coverage in `tests/decorators.rs`.
- Keep PRs focused; unrelated cleanups belong in separate PRs.
