Hello,

here's the new patch for GNU XaoS, I added it to maths.scm, fixed the
("gettext" ,gnu-gettext) thing but didn't add gpl3+ to the licenses
because I couldn't find any file with it.

I was going to commit this patch but now I don't know: should we wait
for a reply from the maintainers about updating xaos release on gnu.org?
Or maybe push this patch now, and change the origin URL later (if there
will be a response)?

Our convention is to use the following commit message:

gnu: Add xaos.

Our (gnu packages image) module uses (gnu packages maths).  I wouldn't
add this circularity, I think it was better to have xaos in a separate
module.  But actually I don't know if it's a real issue and what our
policy on such things is.  I hope more experienced guix/guile people
will tell if we should avoid such circularities.

No, this shouldn’t be blocking packaging.  (It’s really a thankless side
activity of trying to get GNU maintainers to follow GNU conventions. ;-))

Sorry for bumping, just to prevent this package from burying in ML.

Originally Fabian sent a patch for separate "xaos.scm" file.  Then
Andreas suggested to move it to "maths.scm".  But this will lead to the
mentioned circularity:
  (gnu packages image) already uses (gnu packages maths)
and after this patch:
  (gnu packages maths) will use (gnu packages image).

Is it OK to leave it like this, or should 'xaos' be left in a
separate file?

It’s OK to leave it as is.

Module circularity are not a problem, unless there are circular
*top-level* references.

That is, if maths.scm does, say:

  (define foo libpng)

and image.scm does:

  (define bar lapack)

then we have a problem.

Great!  Though I believe it's preferable to avoid module circularities
if possible, right?

Yes, but it’s also hard, unless there’s one package per module.

[PATCH] Add package definition for GNU XaoS

[Fabian Harfert]

[-- Attachment #1: Type: text/plain, Size: 416 bytes --]

Hello,

this is my first contribution to this project.  I hope everything is
right with this package definition for GNU XaoS
(see https://www.gnu.org/software/xaos/).  It's a nice program to
discover fractals, so I decided to use it for my first packaging
attempt.

"guix-lint" worked fine and without error messages after I had
corrected some little things. Please let me know if something is wrong.

This program is a lot of fun!

Some of the files say "GPL 2 or later" and some say "GPL 3 or later".
What's the typical way to denote that in the license field?

Otherwise, looks good to me!

I think we can just use a list with 2 licenses, but I didn't find GPL3
in the source code, what files do you mean?

You're right. I did `grep -rIi gpl` and didn't notice that all of the
GPL 3 results were describing the licenses of the dependencies.

Hello,

I think it would make sense to add it to maths.scm, to avoid the profusion
of modules.

It is not available on the GNU ftp server?

There is <http://ftp.gnu.org/pub/gnu/xaos/> but it has a very old version.

Maybe it would make sense to kindly remind them to put their releases
on ftp.gnu.org. That would also allow us to be notified of updates
(which could be used as an argument).

Fabian, since you have a special interest in the program, would you like
to do this?

I couldn't get information about who's the maintainer of GNU XaoS for
GNU, but I have sent a mail to the person who owns the GitHub
repository.

According to GNU's records, Zoltan Kovacs <kovzol@gmail.com> is the
maintainer of Xaos.

Hello, great attempt!  And thank you for showing this awesome program!
I didn't know about it.

It should be:         `(("gettext" ,gnu-gettext))
