Hey,

This line is redundant; ``out'' is implicit.

> +    (propagated-inputs (list ngspice))

Can you try to avoid propagating this somehow? Propagation is a last-resort
measure, and usually we try to do something like patching invocations of
external commands to refer to the full store path. (Although, looking at
the ``modify-phases'' below, it seems like you already do that, so I guess
you'll only need to move ``ngspice'' to ``inputs''.)

Please use the new style ``(list ...)'' instead of ```(...)''.

> +       (modify-phases %standard-phases

You'll need to gexp this under the new arguments style: ``#~(modify-phases ...)''.

This looks pretty redundant. Try using this instead:

> +               (call-with-output-file "etc/xdg/qucs_s/qucs_s.conf"
> +                 (cute format <>

And add this to ``arguments'':

  #:modules `((ice-9 format)
              (srfi srfi-26)
              ,@%gnu-build-system-modules)

to import ``format'' and ``cute'', respectively.

I think this description would probably be better and far more succint as:

[Message part 1 (text/plain, inline)]

Hello Garek Dyszel,

For the sake of completeness, I've tried to package "qucs-s" already:
  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=56768

Wasn't finished the process though due to issues and the lack of time,
but maybe two incomplete patches could be merged into a working one.

Thanks,

- Artyom

( and Artyom,

I synthesized my last version of this package with Artyom's version in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=56768.
Starting over from that version, more or less, automatically fixed the
following issues:

1. (outputs '("out")) removed
2. (propagated-inputs (list ngspice)) removed
3. (arguments `( --> (arguments (list : style changed

Further changes:
1. Overly long description shortened by blending ('s suggestion and Artyom's version.
2. Regexps in the (substitute*) procedure now correctly detect and replace the lines where ngspice and octave are referenced in qucs/main.cpp. 

Let me know what you think.

Thanks,
Garek

To conserve lots of horizontal space, consider moving the ``modify-phases''

You can just do ``(search-input-file inputs "bin/octave")'', no need for the
leading slash. Also, wouldn't you want to patch in the paths for Xyce,
SpiceOpus, and Qucsator, too?

Hi (,

I applied your fixes, but in the process found that qucs-s had already been successfully added before by looking at the package definition for libngspice. This led to the following bug link: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27344#236.

It looks like support was later dropped because qucs-s still depended on Qt4 at the time, mentioned in this thread: https://lists.gnu.org/archive/html/guix-devel/2016-02/msg00596.html.

This suggested it would be a good idea to start from the commit where qucs and qucs-s were removed. Now I'm hacking those old package definitions to work with Qt6. qucs-s 0.0.24 still depends on qt5 (which is already out of date), and I don't want to have to update it right away when this Qt security issue comes up again this year.

I'll send an updated patch when that's done. Sorry for jumping around among existing package sources; I suppose how it worked out this time.
