A Flake8 plugin to catch common issues on Scrapy spiders.

## Issue types

| Code  | Meaning |

| ---   | --- |

| SCP01 | There are URLs in `start_urls` whose netloc is not in `allowed_domains` |

| SCP02 | There are URLs in `allowed_domains` |

| SCP03 | Usage of `urljoin(response.url, '/foo')` instead of `response.urljoin('/foo')` |

| SCP04 | Usage of `Selector(response)` in callback |

This is a work in progress, so new issues will be added to this list.
