While the initial purpose of this repository was implementing the lists of flake8 plugin entry points described below, the machinery is also well suited for reporting when flake8 plugins are added to or updated on PyPI. Accordingly, whenever these entrypoints lists are updated, information on new/updated packages is:
- Tweeted at @Flake8Plugins (via tweepy)
- Pushed to the RSS feed at https://github.com/bskinn/flake8-bot/raw/master/feed/feed.rss (via python-feedgen)
The data used to persist historical package data for the RSS feed is curated here; if documentation of the schema used there would be helpful, please open an issue.
flake8 uses the Python packaging entry_points mechanism
as its hook for registering plugins.
It supports two types of plugins:
"checkers"
and "formatters,"
which are registered via the flake8.extension and flake8.report entry points, respectively.
For both types of plugins, if multiple plugins try to register with the same entry-point name (the portion of the value before the equals sign), all but one of the plugins will ~silently not be loaded.
Thus, the goal of this repository is to automatically assemble as complete and current a list as possible of the entry-point names claimed by plugins on PyPI, to allow authors of new plugins to confidently choose entry-point names that will not conflict with other, pre-existing plugins. It also seeks to identify those checker plugins whose entry-point names do not conform to the valid format (see the lower half of this page).
The set of PyPI projects surveyed to create these lists can be retrieved here, and the intermediate datasets used to create the lists are available in JSON format, zipped in this file. If there is interest (please open an issue if so), I can add documentation of the JSON schema used in these two files. If there are any flake8 plugins missing from these lists, please open an issue (or PR) as well.
