There’s this weird requirement that for the sake of i18n, we must not
construct synopses/descriptions like this:

  https://guix.gnu.org/manual/devel/en/html_node/Synopses-and-Descriptions.html

I’d suggest something as shown below.

Could you update the patch along those lines?

Thanks,
Ludo’.

Is that a specific rule for Guix? GNU gettext allows format strings,
and its manual refers to

  https://people.csail.mit.edu/jaffer/slib/Format-Specification.html

for format string syntax in Scheme. For Guile specifically,
it refers to (ice-9 format).

Cheers,
  Konrad

Specific to the ‘guix-package’ domain, even.

Concretely, the idea is that <package> objects carry the untranslated
English-language synopsis and description.  This is useful for things
like ‘guix search’ or for web page generators, because they can query
translation explicitly when they need it.

We could allow constructed strings in there, like this:

  (package
    ;; …
    (synopsis (format #f (G_ "This is a ~a compiler") "C")))

But in that case, we’d have to perform translation right in the ‘G_’
call, and thus <package> would end up carrying a translated string.

So far we’ve managed to avoid that, it’s a constraint, but hopefully one
we can live with.

I hope that makes sense!

Thanks for the explanation! That all makes sense, it's just not very
obvious.

I'll send a revised patch in which all synopses and descriptions are
literal string.

Cheers,
  Konrad.

xgettext recognizes (synopsis "foo"), but it won’t catch the variables
defined above, because they’re not preceded by the ‘synopsis’ keyword or
anything.

That’s why I proposed in <https://issues.guix.gnu.org/issue/38436#2> to
arrange to keep the string wrapped in (synopsis …).

It’d be great if you could give it a spin, or I can make the change on
your behalf if you prefer.

Apologies for making something simple somewhat complicated!

Thanks,
Ludo’.

OK, so what's the exact rule? If the literal string has to be right
after the symbol "synopsis", then your optional-arg approach shouldn't
work when the argument is supplied at the call site (in
gfortran-toolchain).

That would still leave the option of doing something like

  (define-public gfortran-toolchain
   (package (inherit (make-gcc-toolchain gfortran))
     (synopsis ...)
     (description ...)

Cheers,
  Konrad.

Good point!

The exact rule is given the the ‘--keyword’ options in
po/packages/Makevars.  Namely, xgettext will recognize:

  (synopsis "…")

Thus, something like:

  (define* (foo #:key (synopsis "…"))
    …)

works.

Now, for gfortran, you could resort to a not-so-fancy hack (used in
‘define-word-list-dictionary’ in (gnu packages aspell)) like this:

  (let-syntax ((synopsis (syntax-rules () ((_ str) str))))

Quite an effort for this little thing, but I couldn’t find of anything
simpler.

Great, good to know!

It looks like I still don't understand how this works. Why wouldn't
the simpler

   (let ((synopsis (lambda (_) _)))
     (make-gcc-toolchain gfortran #:synopsis (synopsis "…")))

be sufficient? And is there a good reason to prefer such constructs
to

  (define-public gfortran-toolchain
   (package (inherit (make-gcc-toolchain gfortran))
     (synopsis ...)
     (description ...)

which I think expresses the intention more clearly?

Cheers,
  Konrad

Ah yes, that would work too.

Oh I guess I had overlooked this proposal, I agree that it’s nicer.

Apologies for the confusion!

Patch submitted. It's probably also the shortest possible
patch to get the desired result.

Applied, thanks!  I fixed that typo that Jonathan reported.
