I was introduced to this project and I think it would be a good option to either incorporate or use as a dependency: https://github.com/nexB/debut |

A package will typically have many files within it which may have different licenses that govern their distribution. This is why debian typically contains all the licenses in their copyright text rather than declare a package license. This change adds a pkg_licenses property which is a list of strings that represent licenses within a package. Tests for the new property are also added. This is work towards tern-tools#499 Signed-off-by: mukultaneja <[email protected]> Signed-off-by: Nisha K <[email protected]>

We use a new pip package "debut" to parse Debian style copyright texts. - Added debut as a requirement. - Added functions in common.py to parse the copyright texts and to collect a list of licenses for each package to be filled in a Package object. - Added functions in the default generator to list all the package licenses found. - Added a check for "deb" package format in order to parse the copyright text so this functionality is restricted to deb style packages only. Fixes tern-tools#499 Signed-off-by: mukultaneja [email protected] Signed-off-by: Nisha K <[email protected]>

Describe the Feature
Debian packages do not contain license metadata. Instead, the license information is contained in the copyright text. This results in an empty license list when you run Tern with the default output against a Debian image/BaseOS.
Use Cases
This would be helpful for the default output of Tern, primarily when running against Debian base images.
Implementation Changes
Add a function that can parse the copyright text for the licenses in a Debian image and report it as the "License" field for a package.
