[bug#55920] [PATCH] build-system: chicken: Added insert-missing-version phase

[Michal Atlas]

Many .egg files don't contain version information,
this causes `chicken-install` to label them {unknown},
which makes it fail compilations whenever a
dependency is tagged with a minimum-version.

I am unaware of a way to force this check to not-happen
and the version information should be included anyway,
so this patch should fix the problem.

I find "stamp-egg-version" funnier.

We don't do square brackets in Guile.  Also, using λ rather than
spelling out "lambda" results in a syntax error.

"lambda".

Note that 'insert-missing-version will always be logged even if the
version is not actually missing.

This construct seems to work fine for me:

> (let ((id (λ (x) x))) (id 0))
$2 = 0

My bad, I only typed the letter λ into a repl and brain-grepped for
syntax error.  Still, the long form ought to be used in my opinion,
because that's the one that editors are more likely to look out for.

Not true, but we conventionally don't use λ in Guix code.  There 
are a good few counterexamples that snuck in over the years, 
though.

Kind regards,

[bug#55920] [PATCH] build-system: chicken: Added stamp-egg-version phase

[Michal Atlas]

* guix/build/chicken-build-system.scm (stamp-egg-version): New phase
Compiled eggs will now always contain some version,
falling back to the guix package version if none is provided by the egg.
(%standard-phases): Inserted the new phase

---

Many .egg files don't contain version information,
this causes `chicken-install` to label them as "unknown",
which causes it to fail compilations whenever a
dependency is tagged with a minimum-version.

I am unaware of a way to disable the version check
and the version information should be included anyway,
so this patch should fix the problem.

Hopefully I understood your comments well.

> Note that 'insert-missing-version will always be logged
I was aware of that but
didn't find anything about making a phase optional,
good thing it has a more sensible name now.

Pushed with some wording fixes.  Cheers
