Flake8 plugin warning for unsafe functions

Alfred the butler

Alfred is a flake8 plugin to warn on unsafe/obsolete symbols. You can use it as a transition tool to eliminate functions, modules, variables you don't want in existing project or you want to avoid in new ones. This plugin requires Python 3.6.

Getting Started

First, install Alfred using pip:

$ pip install flake8-alfred

Then, enable the plugin by configuring a blacklist of Python symbols that should be flagged by flake8. Here is an example of configuration in your project's setup.cfg:

[flake8]
enable-extensions = B1
warn-symbols =
    obsolete_module = Warning! This module is obsolete!
    module.obsolete_function = Warning! This function is obsolete!
    module.submodule.constant = Warning! this variable will be removed!

Here enable-extensions tells flake8 to enable this plugin and warn-symbols is the list of symbols we want to flag in our project, with the associated warning. By default, this plugin doesn't warn about any other symbol.

If you just want to test/run once, you can also pass the configuration directly to flake8:

$ flake8 --enable-extensions=B1 --warn-symbols=$'obsolete_module=Warning!\nmodule.obsolete_function=Warning!'

Local Development

First, clone the repository:

git clone https://github.com/datatheorem/alfred-checker.git

The project uses pipenv to manage dependencies:

$ pipenv install --dev

Then, the test suite can be run:

$ pipenv run pytest
