Subject: 31.0.50; Register previews cannot be disabled
Date: Tue, 04 Mar 2025 12:36:08 +0100

REPRODUCTION:

  1. start `emacs -Q'
  2. eval `(setq register-use-preview 'never)'
  3. type "foo", highlight it, and type `C-x r s a'
  4. type "bar", highlight it, and type `C-x r s'
  5. wait one second

EXPECTED:

  no preview shows

ACTUAL:

  preview shows

NOTES:

  The preview shows on `C-x r i' as well.  Is the `register-use-preview'
  variable supposed to control its preview as well?  If so, then the
  variable should not be documented as

    "Whether to show register preview when manipulating registers."
                                           ^^^^^^^^^^^^
  instead of

    "Whether to show register preview when modifying registers."

  because `C-x r i' does not modify any registers.

Do not use setq to configure this.

Yes, I already replied, the problem is if one set this variable with
setq, the defcustom has a :set function.
So from emacs -Q here:

(customize-set-variable 'register-use-preview 'never)

Then do 3) and 4) from the recipe above.

No preview, as expected.

Yes, I saw it too late, thanks.

Right.  I've already updated the doc string to say using setq is not
effective, so maybe this is all that's needed here.

Yes, for this it should be enough, however there is a little bug when
using never and trying to do C-h, the minibuffer exit with "No register
specified", which is wrong, the preview should popup with full
capabilities, here the needed changes:

[I just re-tested with `customize-set-variable' and the setting pertains
to `C-x r i' as well, so the wording above needs corrected.]

P.S. This is not theoretical: When I was figuring out the way to change
the behavior of `C-x r i', I found and *ignored* this variable, as it
said "when modifying".  I thought to myself: "These folks are precise
with their words, so there must be some other variable." :)

Perhaps using:

"Whether to show register preview when using registers." ?

Don't know what the best wording would be, Eli WDYT?

PS: You can also disable preview without touching the default value of
register-use-preview (keeping traditional) by modifying the value of
register-preview-delay.

Which register-related commands are _not_ supposed to show the
preview?  Knowing that will allow to decide which wording will be
appropriate here.

All register commands use preview AFAIK.

Then I think this will be clearer:

  Whether register commands should show preview of registers that have values.

Perhaps "non-empty registers" instead of "registers that have values"?

  Whether register commands should show preview of non-empty registers.

Otherwise, LGTM.  Thank you, Eli!

Is it really better?  Someone might think, for example, that a
register whose value is an empty string could be considered "empty".
We don't use the word "empty" anywhere in the "Registers" node of the
Emacs manual.  Doc strings do use that, though.  So maybe do both:

  Whether register commands should show preview of registers with non-nil values.

Good point!  I apologize for not consulting the manual first.  Thanks
for the guidance!  Let me try again.  The manual says:

  All of the commands that prompt for a register will by default display
  a preview window that lists the existing registers (if there are any)
  and their current values, after a short delay.

  [Later, the manual also says "show" instead of "display".]

To match the existing terminology, we could say:

  Whether register commands show preview of current register values.

Not sure if we need "should"; feel free to re-add it:

  Whether register commands [should] <display|show> preview ...

And then someone comes up complaining that we don't show nil values?

What was wrong with my last suggestion that required removing the
"non-nil" part?

Ha-ha!  The manual calls such registers non-existent (e.g. "lists the
existing registers"), so I thought that much is given: no register, no
current value.  However, as a long-term maintainer, you know best what
wording might cause support headaches down the line, so your "non-nil"
variant LGTM.  Besides, my problem was with the word "modifying", and
that was addressed already.  Thank you for your patience!
