license-scanner 0.2.7

No project description provided

license_scanner

Find all licenses needed by the package in your python environment. It will sort all package by license.

Install by pip

pip install license_scanner

Usage

license_scanner

Check within you pipeline

You can make your pipeline fail if a project does not have the correct licenses. To do so create a pyproject.toml and add underneath tool.license_scanner two lists allowed-licenses and allowed-packages. If a package does not have license in allowed-licenses AND it is not in allowed-packages it will throw an error.

[tool.license_scanner]
allowed-licenses = [
  "MIT",
  "apache software license",
  "apache software license v2",
  "apache software license v3",
  "BSD license",
  "BSD 3-clause license",
  'GNU lesser general public license',
  'GNU lesser general public license v2',
  'GNU lesser general public license v3',
  'Python software foundation license',
  'Mozilla public license 2.0 (mpl 2.0)',
  'mozilla',
]
allowed-packages = ["license_scanner"]

To run the license scanner make sure you are in the same directory as pyproject.toml and run license_scanner -m whitelist or python -m license_scanner -m whitelist. It will now throw you an error if your environment has an package with a license you did not approve of.

Example: Github actions

This github actions triggers every time you make a PR to the main branch. With pip install . it installs the current project, next it installs license_scanner, and lastly it runs the check.

Be aware, if you want to do unittest make sure you install pytest AFTER you run license_scanner. Otherwise pytest is in your environment when you check for unwanted licenses.
