According to ngspice documentation, it doesn't have a GUI. There are
many GUIs you can use though.
Properly speaking, ngspice does not have a GUI to drive commands. However, ngspice comes
with a "plot" command, which per this tutorial, is supposed to make a graph
appear in a graphical window.
https://ngspice.sourceforge.io/ngspice-tutorial.html
With some more investigation last week, I determined that ngspice has a --with-x option,
and I believe that the ngspice package in Guix is not using the option. However, I tried
building ngspice myself using this option and I quickly ran into a build error, related
to it not being able to find an an Xaw library. Even with -D libxaw, configure reports
"configure: error: Couldn't find Xaw library". So, perhaps the package was
simply unable to build ngspice --with-x.
I don't really care much about this now, though, as I figured out that ngspice's "plot" command can be replaced by a
similar "gnuplot" command which causes the same graph to be constructed with gnuplot. This works well most of the time.
However, "gnuplot" command does require an extra argument (specifying the image file to save to) and it doesn't handle
axis ranges in quite the same way, so "gnuplot" is not quite a drop-in replacement for "plot" in tutorials.
Oh! OK! Now I get what you meant!
I managed to make it build with the viewport and also moved some deps
from the library to the package itself.
Here's the patch for it. I'll review carefully and commit it during the
next days.
If you want to add anything, please do.
