## Development

```bash
poetry install --with dev
```

```bash
poetry shell
```

Open the `manual_test.py` file in VS Code to see the error messages.

```bash
pytest tests/ -v
```

or (to see `print()`s)

```bash
pytest tests/ -v -s
```

Copy the output of the following script and paste it in the [Flake8 codes](#flake8-codes) section:

```bash
python gen_table.py
```

If changes are not reflected in VS Code after changing something in the package, close it and open it again.

## Deployment

```bash
poetry check
```

```bash
poetry version minor
```

or

```bash
poetry version patch
```

Commit the change in the `pyproject.toml` file.

```bash
git tag
```

```bash
git tag "v$(poetry version --short)"
```

```bash
git push origin "v$(poetry version --short)"
```
