@hesa

@pombredanne , do you have any ideas what I am doing wrong when parsing as reading a scancode produced spdx report, as described above?

Philippe Ombredanne

@pombredanne

@hesa no immediate idea... do you mind to file an issue with a small example?

Henrik Sandklef

@hesa

@pombredanne on my way, thanks

@pombredanne would you like it in scancode-toolkit or tools-python?

Philippe Ombredanne

@pombredanne

that's for scancode-toolkit IMHO

Henrik Sandklef

@hesa

@pombredanne ..... double checked the issue, hope it is useful. Don't hesitate to use me as a test/review resource here

@rijusougata13

Hi, is there any way to test if my installations is successful or not ? I have git cloned , run ./configure.bat and run./Scripts/activate.bat and there were no error !

Philippe Ombredanne

@pombredanne

@rijusougata13 then run "scancode" proper to run a scan. For instance: scancode -clipeu --json-pp - samples -n4

Henrik Sandklef

@hesa

Sorry to bug you all on this list. Have a question about Nexb's license-expression - where do I ask this?

Philippe Ombredanne

@pombredanne

@hesa you do not bug anyone. You can ask here alright :P

Henrik Sandklef

@hesa

Excellent :)

I wrote some words at the end of this issue over at maxhbr/LDBcollector#4
In short, how do I add a "translation" of a license (e.g. GPLv2 to GPL-2.0-only)? Do you have a procedure?

I have some 10-20 license expressions from Yocto that makes https://github.com/vinland-technology/flict scream and shout
I'd rather add the translation to license-expression than to flict

Philippe Ombredanne

@pombredanne

me thinks....

@hesa what you call a translation is a license detection (or you could call it a normalization).
This would typically a job for scancode-toolkit
But you can also use the license expression library for more constrained approach

The license expression parsing operates on license "symbols" each consisting of a key (say the SPDX id or the scancode key) and one or more "aliases" that can be arbitrary strings.

@hesa did you ever try this: https://github.com/maxhbr/LDBcollector/issues/4#issuecomment-827967277 ?

@pombredanne

The translation would be to use GPLv2 as an alias

Henrik Sandklef

@hesa

Whatever we call it, I would like to license-expression to be able to go from "GPLv2" to "GPL-2.0-only" :)

Philippe Ombredanne

@pombredanne

@hesa actually, adding a list of alias to each license record may be the best
https://github.com/maxhbr/LDBcollector/issues/4#

this way they are closest together

and license-expression would just consume this

Philippe Ombredanne

@pombredanne

@hesa at some stage I would also like to integrate flict in scancode.io :)

separate topic :)

Henrik Sandklef

@hesa

@pombredanne I am not sure how to add an "alias". Will this be a new concept in scancode? If so, I'll propose some syntax. If "alias" is already a concept, please show me an example :)

Maximilian Huber

@maxhbr

The LDBcollector allready has these aliases: https://github.com/maxhbr/LDBcollector/blob/generated/aliases/aliases.csv#L686

Henrik Sandklef

@hesa

@maxhbr The column "True", sometimes with the value "False" :), what is it for?

Henrik Sandklef

@hesa

@maxhbr Have these aliases been verified? E.g. X11 is in the table linked above an alias for ICU, but the license text differ although similar, so I am curious what a lawyer would say. Note: I would love to see more aliases in license-expression and your list is impressive :)

From a license compatibility point of view, they're compatible ("the same"), but not when attributing the license (text)?

Maximilian Huber

@maxhbr

The third column indicates whether that is a unique mapping. So if the same alias appears to be mapped to multiple licenses or was flagged ambiguous in the beginning, it is set to "False"

Henrik Sandklef

@hesa

Ah nice

Maximilian Huber

@maxhbr

The x11 / ICU clash comes from the scancode data and was already discussed in https://github.com/maxhbr/LDBcollector/issues/4#

Henrik Sandklef

@hesa

Yes. I am curious if the list of aliases can be used in license-expression (by first adding it to https://github.com/nexB/scancode-toolkit/tree/develop/src/licensedcode/data/licenses).

Looking at the scancode files:
$ head -7 x11.yml
key: x11
short_name: X11 License
name: X11 License
category: Permissive
owner: XFree86 Project, Inc
homepage_url: http://www.xfree86.org/3.3.6/COPYRIGHT2.html
spdx_license_key: ICU

Is this the origin of "your" circular alias?

Maximilian Huber

@maxhbr

yes

in the SPXD list, X11 and ICU are two independent licenses, and this joins these two. this violates the rule that the main IDs never have clashes with aliases ...

Henrik Sandklef

@hesa

Hmmm... OK :(

Philippe Ombredanne

@pombredanne

If "alias" is already a concept, please show me an example :)

an alias is something in license-expression, but not in scancode. IMHO this would be a list of strings naned aliases

@maxhbr re:

This would be perfect!

Philippe Ombredanne

@pombredanne

@maxhbr @hesa re:

I would rather say that SPDX got it differently possibly not right.
But basically:

what scancode calls x11 and SPDX calls ICU originated at X11 not ICU. It is mapped to SPDX ICU alright in SC data.
what scancode calls x11-xconsortium and SPDX call X11 is really specific to the X consortium. It is mapped to SPDX X11 alright in SC data.

But I reckon this may need some thinking wrt. to use as aliases. The simplest may be to ignore the scancode key in the set of license symbols and only use SPDX and aliases

Hi everyone I am Aditya an undergrad student from India, I just finished setting up my development environment for scancode because I want to contribute to this project and I am good with python, django, html, css and ready to contribute so if there are any issues I can work on to understand codebase please let me know.

Philippe Ombredanne

@pombredanne

@adii21-Ux welcome :wave:
Please see https://aboutcode.readthedocs.io/en/latest/contributing.html

@adii21-Ux

Hello I was going through scancode-toolkit documentation and here (https://scancode-toolkit.readthedocs.io/en/latest/getting-started/newcomer.html) I found that there are these three points about scan which are repeated in two section namely Try Scancode Toolkit and Installing Scancode and I don't think its necessary in both topics.

Philippe Ombredanne

@pombredanne

@adii21-Ux good catch :) the doc needs some significant love alright (much more than just a few typos)
