Hi,

For some reasons, the Opam importer is failing for coq-of-ocaml:

My guess is that the package is missing a description? I vaguely recall
running into this or a similar error when trying to import Infer, but
I'm not sure how I fixed it.
Based on the backtrace, just modifying beautify-description? to act as
the identity function when the input isn't a string should be enough.

ps.:
This is why Scheme should have a Maybe type instead of this mess of
overloading boolean false. :)
Or at least Guile should have an optional type checker like MyPy.

Thanks.  If no one beats me, I will give a look.  But for now it is low
in my list. :-)

Hm, I do not think Maybe would change something if the «package is
missing a description».  At best, Maybe would be another way to catch
the errors instead of raising the Backtrace, no?

And I do not think that a type checker like MyPy would raises something
here if the issue comes from the missing upstream description, no?

Something like QuickCheck seems required and would raise the bug,
eventually.  Oh wait, guile-quickcheck is around [1] and used by
Disarchive; therefore already an indirect dependency of guix. :-)

That’s said, nothing prevents Guile to have a Maybe monad.  But I think
this way of programming is not popular among Schemers. :-) And I agree
that a type checker would prevent many issues.  Even, I remember talking
this topic back on December 2018 around this event:
<https://lists.gnu.org/archive/html/guix-devel/2018-12/msg00049.html>. ;-)


Cheers,
simon

Since then, this has been fixed:

guix import opam coq-of-ocaml
...
(description
   "This package lacks a description.  Run \"info '(guix) Synopses and
Descriptions'\" for more information.")
...

So, closing :)
