bug#30757: Better manipulation (suppressing, examining type) of warnings from *Warnings* buffer

[Noam Postavsky]

Severity: wishlist

It would be nice if warnings in the *Warnings* buffer came with some
kind of button to let the user add the relevant value to
warning-suppress-types or warning-suppress-log-types.

Adjust strings according to your personal preference. The button names
are a tad verbose as well :-)

Reading your message on emacs-devel, I guess you'd want this kind of
change to be made permanent? So customize-push-and-save of the
resulting values?

Ah, yes, something using customize was more what I had in mind.

Also, potentially reusing the Warning(foo) prefix for the button might
save some space, the different types of suppression could accessed by
different keybindings/mouse clicks (maybe that conflicts with the
"easy to use" goal, though, not sure).

Here's what I've got so far. Suggestions welcome for wording, style
changes, etc.

It works fine for me, but I have warning-suppress-types and
warning-suppress-log-types set to nil, so it might well fail for
people who have already set those manually.

"+++" means this change was documented in the manual(s), but this
change wasn't, AFAIU.  Shkuld this be documented in the ELisp manual?

This entry should be made more clear.  "Warning types" is never
explained, the reference to 'display-warning' is confusing (this is a
user-level feature, so why mention the function which is involved?),
it is unclear what buffer is alluded to by "the buffer it uses", and
the difference between "warning popup" and "warning itself" is left
unexplained.

Likewise here: the difference between "disable popping up" and "never
generate" is unclear.  maybe a different wording will clarify that,
but I cannot suggest one because frankly I don't understand well
enough what each one does.

etc/NEWS says:

  +++ indicates that all necessary documentation updates are complete.
      (This means all relevant manuals in doc/ AND lisp doc-strings.)

I'd looked through the manuals and couldn't see anywhere where I
thought it should be documented, hence I only changed the
doc-string. We can go for '---' in that case.

I've rewritten it. See attached.

Yes. I'm stuck between being precise but verbose, and more general and
succinct, and expressing the permanence of the resulting change. I've
make another attempt, although I'm still not entirely happy with it,
especially since the button texts are now quite long (I thought about
using the verb 'hide', but that's not accurate either).

"---" is correct if a change needs not be documented, yes.

In this case, I wonder whether we should document this where
warning-suppress-types etc. are documented.

Instead of the vague "generation" I'd suggest to say explicitly that
its logged in the *Messages* buffer.  Otherwise, this text is a
significant improvement, thanks.

I think we should make similar changes in the help-echo strings.

Perhaps taking Drew's suggestion to popup a *Help* window would give
more room to be descriptive?

It would, but I thought the target user here was someone who doesn't
necessarily know much about how to configure stuff in Emacs, but just
wants to disable an annoying warning, so a long verbose detailed
*Help* window might be counter-productive.

I think everybody agreed that the feature was good, but there was some
discussion about the wording, so the patch was never applied.  I've now
respun the patch for Emacs 28, and tweaked the wording (and made it
pretty brief).  If anybody wants to change the wording, please do so,
but I don't think we should let that stop us from adding the
functionality, so I've now pushed it.

I think this one was a victim of when I moved to a mac, and it got
orphaned. Thanks for this, although youʼre running the risk of me just
posting patches and waiting for you to apply them :-)

+1

It would be good for the button/link to open *Help* with a more
complete description of the warning.  And there (in *Help*) there
could be buttons/links to suppress things.

In addition, we might have a command or commands that would
show such *Help* regardless of whether the warnings are being
shown.  In *Help*, if the warning is currently not being
shown then the button/link would enable showing it (i.e.,
the button toggles the behavior show/suppress).

That sounds like a whole new feature request :-)

I don't think there's anything preventing that from being added later.
