There's no need to show a screenshot, I believe you.  It's just that I
cannot reproduce the problem: typing C-s over and over wraps around at
the end of the buffer and goes to the beginning.  So I wonder what is
different on your system that makes this not work.

FWIW, I cannot reproduce it here as well.

Typing C-s over and over does wrap around at the end of the buffer.
But that shouldn't be the behaviour when isearch-wrap-pause is set to
`no' or `no-ding', right?

The following is an excerpt from the documentation I'm referring to
[https://www.gnu.org/software/emacs/manual/html_node/emacs/Repeat-Isearch.html]

"You can control what happens when there are no more matches by
customizing the isearch-wrap-pause user option. If it is t (the
default), signal an error. (Repeating the search will wrap around.) If
no, issue a ding and wrap immediately after reaching the last match.
If no-ding, wrap immediately, but don’t ding. Finally, if nil, never
wrap, but just stop at the last match."

Please let me know if I'm missing anything here.

Here it says "If no-ding, wrap immediately, but don’t ding."  And that
is what I see.  Where is the problem, or what am I missing?

For more clarity, here's an example.

Assume it's a plain vanilla emacs install with all options set to
their default values, and it has in it a buffer with the following
content (of just 3 lines).

Line one of buffer
Line two of buffer
Line three of buffer

If the point is at the beginning of the second line, and we issue a
C-r and start typing the following characters "L", "i", "n", "e", " ",
the point would be moved to the first line. If we continue to type
"t", the minibuffer will display "Failing I-search backward" and the
point will still remain on the first line. If we press C-r again, the
minibuffer will display "Wrapped I-search backward" and move the point
to the third line.

This is the default behaviour (with isearch-wrap-pause set to t). I
can see the documented behaviour when I set the value to nil i.e. no
wrap around.

But when I set the value to `no' or `no-ding', I was expecting the
point to automatically move to the third line immediately after typing
"t" as mentioned in the above use case. Atleast, this is what I could
understand from the documentation. Please correct me if I'm wrong.

When I set the isearch-wrap-pause option to `no' or `no-ding', it
still displays "Failing I-search backward" on entering a non-matching
character. I still have to press C-r again to wrap around. This is the
same behaviour as having set the value of isearch-wrap-pause to t.

Ah, your expectations are wrong: Isearch only wraps silently if you
repeatedly type C-r without changing the search string.

Ahh ok. That clarifies. Thanks for the explanation. And thanks for
your time as well. Please close this bug.

On a side note, automatically wrapping during search string input
would be a cool feature though. ;)

I think this is the expected behavior.  This feature only controls
wraparound of repeated Isearch.

It was never intended to wrap around on typing a letter or yanking a text.
If such a behavior is a good idea, it could be added as a new value
to this variable.

Please try the following patch after setting isearch-wrap-pause to the
new value 'auto-repeat':

Hey Juri,

Regret the delayed response.

Yes, I do believe this would be a good idea.

Let me try this patch atop emacs-28.1 and get back to you.

No problem with the delay.  Thanks for confirming that it works.

Now we have to find a better name to describe what it really does.
Probably it should have the prefix "no-" since it makes no pause
like the existing two values 'no' and 'no-ding':

  :type '(choice (const :tag "Pause before wrapping" t)
                 (const :tag "No pause before wrapping" no)
                 (const :tag "No pause and no flashing" no-ding)
                 (const :tag "Disable wrapping" nil))

This raises the question: should it ding and flash on wrapping?
Or two new separate values are needed: one to ding when wrapping
on typing a character, and another not to ding?  To ding, or not to ding?

Definitely ding. Lot of people do prefer visual feedback.

How about this?

  :type '(choice (const :tag "Pause before wrapping" t)
                 (const :tag "No pause before wrapping for
non-incremental search" nis-no)
                 (const :tag "No pause and no flashing for

                 (const :tag "Absolutely no pause and no flashing"
no-ding)  ;;This will cover non-incremental searches as well
                 (const :tag "Disable wrapping" nil))

I suppose non-incremental search here means repeatable search,
i.e. the search that is being repeated with C-s C-s.
Maybe then better to emphasize this difference explicitly?
For example: 'inc-no' and 'inc-no-ding' for incremental wrapping,
and leave the existing 'no' and 'no-ding' for repeatable wrapping.

I too thought of it as this would preserve the original meaning of the
current values in letter and spirit.

But won't it give the notion that 'inc-no-ding' and 'no-ding' are
mutually exclusive?
Meaning, setting value as 'inc-no-ding' won't wrap for repeatable
searches, and setting 'no-ding' won't wrap for incremental searches.

Shouldn't we be conveying that one of the options includes/performs
the behaviour of all the other ones, in addition to handling the new
scenario?

It's difficult to choose self-descriptive symbols.  So we need to have
just good enough symbol names, then describe their exact meaning in the
documentation.

Then I guess introducing 'inc-no' and 'inc-no-ding' for incremental
wrapping should do as it preserves the meaning of the existing values.

Just  one more question.

Why shouldn't the behaviour of 'no' and 'no-ding' be changed to handle
incremental searches as well, instead of introducing new values?

Good question.  The reason was to maintain "backward-compatibility".
But do we really need to restrict the existing values only to C-s C-s,
and not to incremental commands?  In this case here is a new patch:

I tested your patch and it works, Juri.

Yep, "backward-compatibility" is one reason. But, in effect this patch
will also retain part of the original behaviour.

The problem is that I was stuck when trying to document the
new non-repeatable incremental behavior of the old values
`no' and `no-ding' of `isearch-wrap-pause'.

Currently this is documented in the Info node
(info "(emacs) Repeat Isearch"):

     You can control what happens when there are no more matches by
  customizing the ‘isearch-wrap-pause’ user option.  If it is ‘t’ (the
  default), signal an error.  (Repeating the search will wrap around.)  If
  ‘no’, issue a ‘ding’ and wrap immediately after reaching the last match.
  If ‘no-ding’, wrap immediately, but don’t ‘ding’.  Finally, if ‘nil’,
  never wrap, but just stop at the last match.

The problem is that everything in this Info node is about
repeating the search with `C-s C-s'.  I can't find a suitable place
to describe the additional incremental wrapping here.

Why is this node not appropriate for whatever you want to document?

Or maybe I don't have a clear idea of what you want to add there?

The new additional behavior of ‘no’ and ‘no-ding’ is to wrap on appending
a character to the search string.  Maybe then something like this:

LGTM, since that node already describes what happens when the search
wraps.
