## Formatting the code

We use `stylish-haskell` 0.14.6.0 for Haskell code formatting.
We use `fourmolu` for Haskell code formatting. See [tools.nix](./nix/tools.nix) for the `fourmolu` version used in CI.

Either enable editor integration or call the script used by CI itself:

```bash
./scripts/ci/run-stylish.sh
./scripts/ci/run-fourmolu.sh
```

When using Nix, you can use the following command, which will build and use
the right version of `stylish-haskell`.
the right version of `fourmolu`.

```bash
nix develop -c ./scripts/ci/run-stylish.sh
nix develop -c ./scripts/ci/run-fourmolu.sh
```
