Description

I want to find out the files without licenses/copyright content using scancode. How can I do that? Also if I want to put a filter exclusively for finding images inside the source code repo, is it possible?

System configuration

For bug reports, it really helps us to know:

• Linux
• What installation method was used to install/run scancode? source

I want to find out the files without licenses/copyright content using scancode.

There is no explicit filter for that but there is a filter "--only-findings" that does the exact opposite.
You could either:

1. contribute a plugin based on only-findings to do the opposite
2. post-process the JSON results separately to collect things without copyright/license

Also if I want to put a filter exclusively for finding images inside the source code repo, is it possible?

well, we have all the data in the scans for that: mime type, file type and extensions as well as an is_media flag https://github.com/nexB/scancode-toolkit/blob/f488b6c2172f588e80e1b764ed6158444e92b8ef/src/typecode/contenttype.py#L480 but nothing that can as a summary tell you: this file is an image. I think we could add this to contenttype.py as is_image
Then once that is done, we could add a generic option to filter based on any of the is_*** flag?
Just some ideas.

https://github.com/nexB/scancode.io/ does display files without a license or without a copyright is better suited for this since it is backed by a database. I am moving this issue there!

@vvscloud this is an example screen shot from scancode.io

You can see how the files without licenses and without copyright are shown in the pie charts.
And clicking it leads to the list:

The same data is available through the API for integration in your workflow.

A new "Resources detected license expressions" panel was added in the project details view.
You click on the "no licenses" entry to view the list of files without licenses.

Alternatively, you can use the "Detected license expression" filter in the resources list view.
