Hello Sharlatan,

thank you very much for your patch, Weir and generative algorithms for

art graphic production are very interesting

We should check the overall license status of weir, see below

3. Some code suggested by @lispm (in src/auxiliary/dat.lisp, src/various.lisp). There

are links to the original suggestions

AFAIU the license in 1. means that that piece of code is not free

software, since "verbatim copy" AFAIU is not free

The license in 2. AFAIU is free software, license:expat or other? Can

you clarify please?

The code referenced in 3. is suggested by lispm in

https://gist.github.com/inconvergent/8b6ccfbde4fca7844c1962082ef07a7e

and AFAIU is not a trivial patch with no clear license: I really don't

know how this kind of code is normally evaluated from a GNU FSDG point

of view

I think we need some guidance from someone more experienced in license

issues.

Thanks! Giovanni.

Patch pushed as 5763eba94cccc4019cb07b0cac6c16132c741e11.
I managed to get the tests working on SBCL, it was a file access
permission issue. However a few tests are failing on ECL, so I disabled
them for now.

Hi Giovanni,

I pushed the patch just before receiving your email about the possible

license issue. Bad timing...

I'm not a lawyer and I'm not sure what the final license of Weir is, so

it would be nice if some license expert could give us their opinion on

this. And in case there's a problem, I'll revert the patch.

I am almost sure that the licenses for the points 1 (license clearly

stated by Paul Graham) and 3 (no license for that code means "classic"

full copyright) are non-free.

Please do not forget that a reasonable copyright and license audit is

one of the things to do before committing, so please do not skip this

important step just IANAL ;-)

Please can you yust revert this patch and give us some time to settle

this issue?

Thanks! Giovanni

Concerning point 1, there's a modified version of the code from

"On Lisp" at https://github.com/DalekBaldwin/on-lisp.

The file "on-lisp.asd" contains an extra indication by Paul Graham about

the license:

Original code:

to use the code in any nonprofit activity, or distribute free

verbatim copies (including this notice), is encouraged to do so.

Modified code:

the original, that's fine. --pg

Unfortunately AFAIU the "Modified code" license addition (where does it

comes from?) still does not qualify the license as free.

"On Lisp" official page is here:

http://www.paulgraham.com/onlisptext.html,book and code (mechanically

extracted from the TeX source files of _On Lisp_) is copyright by Paul

Graham. AFAIU today both the code and the book are freeware but not

free.

The original code (officially linked in the book web page) is here:

https://sep.yimg.com/ty/cdn/paulgraham/onlisp.lisp?t=1595850613&

A good chance to ask Paul Graham (and Dalek Baldwin... or Kyle Littler?)

to release the code as free software? :-D

Thanks! Giovanni.

P.S.: I'm not familiar with Common Lisp but is it possible that the

functions from "On Lisp" has been somehow replaced or incorporated in a

proper library? ...I'm going to ask on guix-devel.

This alone will not fix the problem with "point 3." of the Weir license,

but would be a start.

Hello Licensing Team!

in Guix we are considering adding a new package, Weir, but we need some

clarificartions about it's license.

This is what I found:

Can you please clarify how to manage the three different licenses

declared above?

AFAIU:

1. the license is not free since "verbatim copy" is not free

2. is a free software, seems a modified version of the expat

license... or other? Can you clarify please?

3. the code (I read it) suggested by lispm in

https://gist.github.com/inconvergent/8b6ccfbde4fca7844c1962082ef07a7eis

not a trivial patch and no license is included, so it should be

"copyright by default", right?

Thank you for your support!

Best regards, Giovanni.
