* gnu/packages/emacs-xyz.scm (emacs-consult)[propagated-inputs]: Add

emacs-vertico.

---

emacs-vertico is an optional dependency so maybe there is a better way

deal with this. Splitting the package into multiple outputs might be a

better idea, but I don’t know how we would do that.

This is certainly an interesting question.  With other Emacs packages,
there is sometimes a contrib version, that adds "more", see e.g. org-
mode or telega.  But those are tied closely to what upstream considers
contrib, so I don't think that applies here.

IIUC selectrum is likewise optional.  Perhaps we should consider not
propagating optional inputs, but rather adding them as normal inputs –
so that byte compilation succeeds, but users won't be forced to have a
rather large elisp library as part of their profiles if it's not
needed.

I've CC'd Maxim to get their input on the matter, the patch otherwise
LGTM.

Regards,
Leo

Yeah, Org has a separate contrib/ directory.

I think this might be the best option.

Hi all,

I actually think we should not add emacs-vertico to the

propagated-inputs, and remove emacs-flycheck and emacs-selectrum as

well. All these are optional dependencies, and we should leave it to the

user to install the ones they want. At least in this specific case, the

three packages (flycheck, selectrum and vertico) are the kind the user

would want to explicitly install. They aren't backend libraries that

ought to remain invisible to the user.

In fact, this is the version of emacs-consult I have installed in my

profile.

Toggle snippet (5 lines)

(package

(inherit emacs-consult)

(propagated-inputs `()))

Also, byte compilation works for me without any propagated inputs. Am I

missing something?

Regards,

Arun

Another option would be to define package variants of ‘emacs-consult’,

that way we would have four packages:

* emacs-consult;

* emacs-consult-flycheck;

* emacs-consult-vertico; and

* emacs-consult.

WDYT?

Guix packages typically come as featureful as possible unless there are
good reasons not too (to minimize the closure size, for example).  In
this case, the added optional dependencies seem to have negligible
effect on the closure size, according to `guix size`; I'd be in favor to
keep the optional dependencies specified for that reason, unless there
are other considerations that I'm missing.

I would prefer not go that route (variants multiplication), especially

when the user already has a way to customize.

My 2 cents,

Maxim

While closure size is normally a good metric, with interpreted
languages like Emacs Lisp you have the added baggage of *propagating*
inputs, thereby installing stuff at user (or system) level, that the
user did not actually ask for.  My personal take on those is to provide
them as inputs where necessary to compile, but not actually propagate
them where not necessary to run.

For example, an Emacs package might require emacs-dash to function at
all and might install some autocompletion stuff with emacs-autocomplete 
or emacs-company (perhaps even both).  emacs-dash absolutely must be
propagated, but unless you're already using autocomplete or company and
thus have them in your manifest, you probably don't want them to be
installed by emacs-foo.  Does this make sense?

I agree. Closure size isn't the right metric for this
case. emacs-vertico and emacs-selectrum aren't really optional
dependencies in the normal sense. The user would only want one of them
in their profile, and never both. Propagating both would rather be a
nuisance to the user.

I agree. Variant multiplication would result in a minor combinatorial
explosion. emacs-vertico and emacs-selectrum are anyway the kind of
package a user would explicitly install in their profile.

Cheers!

Thanks for explaining. It makes sense, although there would probably be

exceptions. I'm thinking for example about emacs-elpy, for which not

propagating optional dependencies would render the package nearly

useless out of the box.

From a purity sense, yes, but propagating autocomplete or company

wouldn't cause any problems in practice, no?

As another possible option to explore to avoid propagation could be to

develop a runpath equivalent for the Emacs compiled format (.elc). More

work, but more definitive!

Thank you,

Maxim

True, that's why those have to be evaluated on a case-by-case basis.

FWIW, I do think that not propagating auto-completion frameworks by

more or less unrelated packages is a good rule of thumb, however.

Packages installed by Guix do contribute to startup times (guix-emacs
autoloads etc.) and if you don't care about a given feature you might
also want to update one package separately from the others (because the
spacebar heater got deactivated), which would lead to a conflict of
propagated inputs.  I'm not sure how well the latter would work in
practice, but it's a thing to think about especially with libraries
that would otherwise propagate nothing.

I think the bigger problem in Emacs is the lacking module system. Even

if you have runpaths, you're still polluting the same global namespace.

Thanks

I just noticed that the “16.4.6 Emacs Packages” section of the manual
has the following paragraph.

     The Elisp dependencies of Emacs packages are typically provided as
  ‘propagated-inputs’ when required at run time.  As for other packages,
  build or test dependencies should be specified as ‘native-inputs’.
  
Since these optional dependencies (‘emacs-autocomplete’ and
‘emacs-company’ in your case) are not needed at runtime, would it make
sense to make them ‘native-inputs’ instead of ‘inputs’?

Thanks Olivier, keeping our list of opened issues relevant is very

valuable.

Since there was no concensus on what to do, and it was not clear the

suggested changes would have improved the status quo, I think it's fair

to close it now.

Done!
