Hello,

Good news: the bug that i had in Emacs 26.3 is not present in 28.1.
With Emacs 28.1 compiled from source and started with "src/emacs -Q" i can
use incremental search (e.g. in dired) including for visible text (found)
or invisible text (not found), and highlighting is correct in all cases.
Also i see in Emacs 28.1 sources that `invisible-p' has been rewritten (in
C), and is more thorough than in 26.3 :-)

Thanks,

Thierry

Right.

Anyway, back to the original issue -- Thierry, you reported this problem
for Emacs 26.3, but do you see it in more recent Emacs versions?

If so, can you give a complete recipe to reproduce it, starting from
"emacs -Q"?

Yep, that is my understanding too: first check both, then each separately.

That's true.  Was that the intention here -- first to check invisibility
of both text properties and overlays and then only check invisibility of
text properties?

I don't see how it's always true:

1. (invisible-p (point))
   checks invisibility of both: text properties and overlays.

2. (invisible-p (get-text-property (point) 'invisible))
   checks invisibility of text properties only.

3. (invisible-p (overlay-get o 'invisible))
   checks invisibility of overlays only.

There is a need for a separate check because overlays
can be opened, whereas text properties can't.

The claim was that invisible-p:

>>> it only tests that there is a text property, not actual
>>> invisibility

and then there's a definition of invisible-p, which indeed only tests
that.  I pointed out that that's not what invisible-p is defined as, or
what it does.

In other words, this:

	;; If the following character is currently invisible,
	;; skip all characters with that same `invisible' property value.
	;; Do that over and over.
	(while (and (< (point) end) (invisible-p (point)))
	  (if (invisible-p (get-text-property (point) 'invisible))

Is fine, but

(eq (invisible-p (point))
    (invisible-p (get-text-property (point) 'invisible)))

is always true.

I checked this again, and I see nothing wrong in the current implementation:

  (invisible-p (get-text-property (point) 'invisible))

is a valid call, because the arg of ‘invisible-p’ can be the actual value
of the ‘invisible’ text property.

(invisible-p (point)) has already been tested in the previous line, but it
only tests that there is a text property, not actual invisibility:
(defun invisible-p (pos)
  (get-text-property pos 'invisible))

If the text property `invisible' has another symbol than t as value and
`buffer-invisibility-spec' is a list (which is the case in dired, see
below), then the text will only be invisible if that symbol is currently
part of `buffer-invisibility-spec' (and that is used by
`dired-hide-details-mode').

buffer-invisibility-spec is a variable defined in =E2=80=98C source code=E2=
=80=99.
Its value is (t)
Local in buffer lisp; global value is t

  Automatically becomes buffer-local when set.

Documentation:
Invisibility spec of this buffer.
The default is t, which means that text is invisible if it has a non-nil
=E2=80=98invisible=E2=80=99 property.
This variable can also be a list.  The list can have two kinds of elements:
=E2=80=98ATOM=E2=80=99 and =E2=80=98(ATOM . ELLIPSIS)=E2=80=99.  A text cha=
racter is invisible if its
=E2=80=98invisible=E2=80=99 property is =E2=80=98ATOM=E2=80=99, or has an =
=E2=80=98invisible=E2=80=99 property that is a
list
that contains =E2=80=98ATOM=E2=80=99.
If the =E2=80=98(ATOM . ELLIPSIS)=E2=80=99 form is used, and =E2=80=98ELLIP=
SIS=E2=80=99 is non-nil, an
ellipsis will be displayed after the invisible characters.
Setting this variable is very fast, much faster than scanning all the text
in
the buffer looking for properties to change.

Actually, I just reverted to the previous version.
But the original change was 66e2e71d556785cd10270931c6fc0424b9dea6a6

Hm...  shouldn't this just be

Hello,

isearch fails to highlight in dired and displays the following error:
[image: image.png]

As dired sets text property 'invisible to a symbol, either:
'dired-hide-details-detail, 'dired-hide-details-information or
'dired-hide-details-link, in order for isearch to properly highlight the
searched string in a dired buffer, the following patch ought to be applied
to isearch-range-invisible:
diff -u isearch.el~ isearch.el
--- isearch.el~ 2019-09-10 02:32:49.000000000 +0200
+++ isearch.el 2022-06-02 17:13:55.490492201 +0200
@@ -2972,7 +2972,7 @@
