PyLicense

PyLicense is a CLI tool that queries license information from one of the following package repositories: PyPI, Anaconda or conda-forge.

PyLicense uses the online information of those repositories, e.g. the license information that is listed on pypi.org/pypi/<packagename>, e.g. https://pypi.org/project/dcs-pylicense/. While this means that the package must not be installed on the local system, it also shows information about the lastest package version and not every possible package version.

Installation

To install the package run

$ pip install dcs-pylicense

The tool registers itself as pylicense. To learn about the available arguments refer to its help:

$ pylicense --help

Usage

PyLicense requires a file in the format of a requirements file. The format is described here.

To query license information of the packages run

$ pylicense path/to/my/requirements.txt
| name       | license   | version   |
|:-----------|:----------|:----------|
| black      | MIT       | 20.8b1    |
| pylint     | GPL       | 2.6.0     |
| pytest     | MIT       | 6.0.2     |
| pytest-cov | MIT       | 2.10.1    |
| sphinx     | BSD       | 3.2.1     |
| twine      | unknown   | 3.2.1     |

It is also possible to read from stdin

$ cat /path/to/my/requirements.txt | pylicense

By default the result is returned as a markdown table. Other format options are available, e.g. output formatting as CSV.

$ pylicense --output-format csv path/to/my/requirements.txt
name|license|version
black|MIT|20.8b1
pylint|GPL|2.6.0
pytest|MIT|6.0.2
pytest-cov|MIT|2.10.1
sphinx|BSD|3.2.1
twine|unknown|3.2.1

By default the Python Package Index (PyPI) is queried. This can be changed with the --repository flag.

For example to query the anaconda package repository use the following command

$ pylicense --repository anaconda path/to/my/requirements.txt
| name       | license      | version   |
|:-----------|:-------------|:----------|
| black      | MIT          | 19.10b0   |
| pylint     | GPL-2        | 2.6.0     |
| pytest     | MIT          | 6.0.2     |
| pytest-cov | MIT          | 2.10.1    |
| sphinx     | BSD-2-Clause | 3.2.1     |
| twine      | Apache  2    | 2.0.0     |
