Dear Guix,

I am hereby submitting a patch series updating volctl to 0.9.3.

This new version relies on python-pulsectl, which this patch series also adds.

Thanks!

I'd reword this as "Re-indent the synopsis line", or alternatively make
it really shorter, perhaps dropping the last "for graphical
applications" bit, which get repeated the description anyway.

I chose the second option and made the synopsis shorter as you suggest.

Tests are typically stripped from the pypi source archive (sdist).  If
you look into the source repository, there are tests under
pulsectl/tests, so it'd be better to fetch the source from git.

Also note that for the cases where using #:tests? #f is actually needed
(when there really are no test suite), a short explanatory comment is
expected (;no test suite).

Please do not include trailing #t in phases or snippets anymore; they
are not needed.  Also prefer using a plain list for arguments and
g-expressions (gexps).

I'd start the description with "This package provides a Python
high-level interface [...]", to make it a complete sentence.

I'd use plural for the last word (player-like clientS), as there could
be more than one client available.

Don't forget to CC my email when sending a revised v2 version with the
above :-).

Ah!  Incidentally, this is what I was aiming to fix when I started the
work on this patch series, but guix lint told me I could update the
version… :D

I tested the new version with ./pre-inst-env guix shell volctl and
everything looked fine with the default systray of EXWM.

I will do a global system update by the end of the week and will see if
I can reproduce and fix the issue.

Sorry, I forgot to mention in my previous reply: here, you could use
(search-input-file inputs "lib/libpulse.so.0"), which has the added
benefit of failing if the file cannot be found in the inputs arguments.

In fact, pulsectl's tests fail because they seem to want to start
a dummy PulseAudio instance, which I expect to fail because of the
restrictions of the build environment.  Here's my post on the mailing
list with some more details:

https://lists.gnu.org/archive/html/help-guix/2023-01/msg00038.html

I added a comment briefly explaining this, but maybe there is
a better way.

Fixed, thank you.

I spent some time squinting at this remark and reading the manuals, but
I can't figure out what you mean.

Could you please give some more hints about the parts I should change
and how?

Done, thank you.

Done as well :D

Oh, good to know, thank you for the suggestion!  search-input-file
actually simplified the code and allowed me to drop the let (which
I copied from the previous version of volctl in fact).

I updated patches 2 and 3 to use search-input-file and attach both to
these E-mails.

By the way, I'd be happy to know whether with debbugs it is better to
attach the updated patches to E-mails with comments, or rather sending
the patches as separate E-mails.
