licomp-toolkit 0.5.5

Simple command line tool to check compatibility between two licenses, given context

Licomp Toolkit

Licomp toolkit is a license compatiblity tool using miscellaneous available compatibility resources and provides replies from all resources.

Introduction

Licomp can be used to help determine if a license is compatible with an outbound license. These compatibility checks needs context which is often missing. The context above must be provided to licomp-toolkit. In short the context is:

• use case - how you use the licensed component
• provisioning - how you provide the component to your user
• modification - if you have modified the component

Licomp toolkit is using the Licomp api to communicate with the Licomp resources. For a better understanding of Licomp we suggest you read:

• Licomp basic concepts
• Licomp reply format

Licomp resources

Licomp toolkit uses the following compatibility resources using the Licomp api: licomp-hermione, licomp-osadl, licomp-proprietary, licomp-reclicense, licomp-dwheeler and licomp-gnuguide.

Using Licomp Toolkit

Command line interface (brief intro)

If you want to check if the following is compatible:

• outbound license "MIT"
• inbound license "LGPL-2.0-or-later"

$ licomp-toolkit verify -il MIT -ol LGPL-2.0-or-later | jq .summary.results
{
  "nr_valid": "1",
  "yes": {
    "count": 1,
    "percent": 100.0
  }
}

In the above example, licomp-toolkit by default chose:

• usecase library- i.e. the licenses component is used as a library (e.g. linking to it)
• provisioning binary-distribution
• modification is not yet implemented

Python module

If you want to check if the following is compatible:

• outbound license "MIT"
• inbound license "LGPL-2.0-or-later"

>>> from licomp_toolkit.toolkit import LicompToolkit
>>> licomp_toolkit = LicompToolkit()
>>> compatibilities = licomp_toolkit.outbound_inbound_compatibility("MIT", "LGPL-2.0-or-later", "library", "binary-distribution")
>>> print(str(compatibilities['summary']['results']))
{'nr_valid': '1', 'yes': {'count': 1, 'percent': 100.0}}
