Subject: [PATCH] ui: Describe package outputs.
Date: Fri, 18 Mar 2022 20:16:39 +0100

* guix/ui.scm (package->recutils): Output outputs with their descriptions,
one per line.
---
Salut Guix,

People have been complaining for a while, that outputs are not really
discoverable [who?].  This patch attempts to fix that by displaying each
on their own line with a (hopefully) helpful description next to it.
It is expected, that these descriptions do not span multiple lines.

Cheers

"gtk3", "gtk4", "module", "src", "woff2", "headless", "installer",

Wouldn't this require #:substitutable? #false?
It's punny but rather inaccurate ...
WDYT of adding a package property to allow packages to document unusual
outputs?

Oh, right, I just put in the most common ones.  Of the ones you cite,
"doc", "examples", "gui", "src" "utils", and perhaps "cargo" make sense
if defined like this, the others appear rather specific.  "python" in
particular sounds like it might have multiple meanings.

You can substitute state secrets, but they will be marked to see who
leaked them.  It's not like all of our outputs are 100% reproducible,
are they? :P

That is literally the first thing I'm doing.  It is unimaginatively
called 'output-descriptions and checked before either of the fallbacks.

Indeed, I overlooked that.  That seems like something that needs to be
documented though (maybe in ‘package Reference’ or ‘Packages with
Multiple Outputs’, perhaps complemented by a linter that checks
that outputs without fallbacks are described in 'output-descriptions').

Greetings,
Maxime.

Should the descriptions be thunked, in case the package modules
are loaded before the locale is set, or if the locale changes during
execution?  E.g., guix-data-service often changes locales, e.g. in
<https://git.savannah.gnu.org/cgit/guix/data-service.git/tree/guix-data-service/model/package-metadata.scm?id=8ab72e633ae700fe58bb3bf72aa155d62c2bc22e#n234>.
I don't know if old processes are reused or new processes are created,
but I'd assume the former.

Greetings,
Maxime.

Hmm, that's an interesting question.  For what it's worth neither
synopsis nor description seem thunked and those are also localized, so
I don't think it'd be an issue.

Those work differently -- they don't use G_ or P_, instead the
localisation is delayed to 'package-field-string' and
'package->recutils'.

IOW we'd have to wrap (assoc-ref descs output) in an (and=> <> P_)?

I don't think that's sufficient, somehow the strings need to end up in
the .po files.  IIRC, there's some magic somewhere to add package
descriptions to the .po files even when they aren't wrapped in
(P_ "foo"), but I cannot locate it anywmore.

I was more thinking of:

(package
  [...]
  (properties
    `((output-descriptions 
         . ,(lambda () ("foo" . ,(G_ "Bar")) ...)))))

though bringing the magic used for package descriptions to
output descriptions would be tidier.

Greetings,
Maxime.

Rather:

  (properties '((output-descriptions
                  ("send-email" (synopsis "send email!")))))

That is, instead of calling ‘G_’, you just use one of the keywords
xgettext recognizes (see ‘po/packages/Makevars’).  The actual call to
‘gettext’ would then be made in (guix ui).

I wonder if we’re going overboard though?

Thanks for moving forward on this!

I get:

Where can I see Appendix H though?  (Real question.)

There is no appendix H, it's an obscure reference to the appendix H of
the x86 instruction set (containing undocumented instructions or here
undocumented outputs 🙂️).

In order to have a more meaningful string, you'd need to add an output
synopsis property to the package like so: 
(properties 
  `(...
    (output-synopsis "send-email" "the `git send-email' command")
    (output-synopsis "credential-libsecret" "the libsecret credential
helper")
    ...))

The second string should (if I got everything right) be translatable
without needing to wrap it in a G_.

Cheers

Thanks for this nice improvement.

--8<---------------cut here---------------start------------->8---
+      (assoc-ref `(("bin" . ,(G_ "executable programs and scripts"))
+                   ("debug" . ,(G_ "debug information"))

+                   ("out" . ,(G_ "everything else")))
+                 output)
+      (G_ "see Appendix H"))))
--8<---------------cut here---------------end--------------->8---

Maybe we could just replace this “see Appendix H” by “undocumented”.

Or if we want to keep the reference, “see the non-existing Appendix H”.

+1!  For those like me who’d otherwise take it at face value.

Thanks,
