flake8-warnings

Python linter that warns you about using deprecated modules, classes, and functions. It provides a CLI as well as flake8 and pylint plugins.

Usage

Installation:

python3 -m pip install flake8-warnings

Now, you can use it in one of the following ways:

1. Directly from CLI: python3 -m flake8_warnings ./my_project/
2. As a flake8 plugin. Just run flake8 ./my_project/, it will automatically detect the plugin.
3. As a pylint plugin. For pylint, plugins must be explicitly specified: pylint --load-plugins=flake8_warnings ./my_project/.

How it works

It analyzes all imported modules, classes and functions and detects the following:

1. warnings.warn function calls.
2. Deprecation decorators like deprecated or deprecation.
3. Deprecation messages in docstrings.

2. astroid is a direct runtime dependency of flake8-warning and it is licensed under LGPL-2.1 License. It allows commercial and private usage, distribution and whatever, don't confuse it with GPL. However, if your legal department is still nervous, just don't make flake8-warnings a production dependency (why would you?), use it only on dev and test environments.
