[bug#54953] gnu: Add emacs-nano-theme

---
This is my first git patch ever. I really hope I did everything correctly. This is imported emacs package from ELPA, but I shortened the ELPA description a bit.

I apologize for any mistakes I made. I never used this method before.

Conventionally, except for composite words, words are written without
spaces. And Λ is not a fancy A, but the capital Greek letter lambda.
You are also mixing Greek and Latin alphabet here, and I don't see why
the lambda, nu and omicron is capitalised here.  My proposal: Νανο.

(Nitpickery reported upstream at
<https://github.com/rougier/nano-theme/issues/26>.  I don't think it
has to be changed downstream in Guix.)

To make lists, use the Texinfo markup @itemize, @item and @end itemize,
then "guix show emacs-nano-theme" can render the list nicely.
Texinfo also has some markup for hyperlinks.

Maybe a reference to the Guix package (I think it's font-google-
roboto?) would be useful here?

Oh I am sorry, I didn't know that.

I agree. If it is fine that the package now will not agree with upstream.

I wouldn't call it that ("consistent") myself and I do agree that it sounds a bit weird, if it is, again, fine, that it will not agree with upstream, I will change it.

It sounds better. However does it matter that it now will not match guix package name but match the emacs package name?

It sadly does not. But Roboto Mono Nerd is not packaged for guix and I haven't checked the license on their assets yet. I believe that Roboto Mono is recommended as a aesthetic matching font.

Best,
Maya.

No problem.  Now you do :)

Many upstreams don't have useful synopses or descriptions, so we often
have to adapt them.  In other words, it's no harm if you put more
effort into synopses and descriptions than merely copying them from
elsewhere, as long as formal requirements are met (e.g. the synopsis is
a short line, the description consists of full sentences, etc.)

As above, we usually strip all marketing words from upstream
descriptions.

That's fine imo.  IIUC nano-theme would be a feature that you can
(require), no?

Last time I checked, Nerd fonts were a special kind of mess that's
difficult to disentangle and more difficult to check licenses on.  I
wouldn't bother too hard.

Is the recommendation important in your opinion?

Yes it is a emacs package of that name. You also then load-theme it, so I guess it's fine.

It looks like it. I didn't felt comfortable packaging it as it looked like they automatically download copyrighted content.

> Is the recommendation important in your opinion?
There is kind of a problem with that. The nano-theme package also provides a method of setting other not theme-related functionality under the nano-mode function. But that function prints an error if Roboto Mono Nerd isn't present on the system. (but does not fail)

As for the recommendation of the Roboto Mono itself, I don't know. The nano packages are all about aesthetics. And the theme optionally sets faces to Roboto (or Fira Code as a fallback font). Weirdly enough, the code also sets some faces to Victor Mono, but there is no mention of that in the package description.

The longer I'm looking at the code, the weirder it gets. It seems like it's not only a them per-se. But rather a visual style that kind-of breaks the borders of normal emacs theme.

Best,
Maya
