Checker

pylic – Python license checker

Reads pylic configuration in pyproject.toml and checks licenses of installed packages recursively.

Principles:

  • Every license has to be allowed explicitly (case-insensitive comparison).
  • All installed packages without a license are considered unsafe and have to be listed as such.

Only installed packages are checked for licenses. Packages/dependencies listed in pyproject.toml are ignored.

Installation

pip install pylic

Configuration

pylic needs be run in the directory where your pyproject.toml file is located. You can configure

safe_licenses: All licenses you concider safe for usage. The string comparison is case-insensitive.

unsafe_packages: If you rely on a package that does not come with a license you have to explicitly list it as such.

[tool.pylic]
safe_licenses = [
“Apache Software License”,
“Apache License 2.0”,
“MIT License”,
“Python Software Foundation License”,
“Mozilla Public License 2.0 (MPL 2.0)”,
]
unsafe_packages = [
“unlicensedPackage”,
]
