highlight-regexp not working after tabulated-list-col-sort
Here is how:
1) M-x package-list-packages
2) M-x highlight-regexp RET parens RET and word "parens" will get
highlighted
3) Click on "Archive" title and sort the list by Archive column
4) M-x highlight-regexp RET parens RET and the word "parens" is not
highlighted. I would like to understand why. hi-lock mode remains
turned on.

I can observe that M-x highlight-regexp does not work for second time
in Dired mode as well.

As the doc string says:
---
Use Font lock mode, if enabled, to highlight REGEXP. Otherwise,
use overlays for highlighting. If overlays are used, the
highlighting will not update as you type. The Font Lock mode
is considered "enabled" in a buffer if its ‘major-mode’
causes ‘font-lock-specified-p’ to return non-nil, which means
the major mode specifies support for Font Lock.
---
So in these modes, changing the text won't update the overlays, and
re-sorting them will remove the overlays altogether. So I don't think
there's any bug here, and I'm therefore closing this bug report.

I wish to use the function highlight-regexp for reasons of
simplicity. The above description does not tell me HOW to use font
lock mode to highlight regexp.
I can see that font-lock-mode is T inthe buffer before and after
sorting. My understanding is that I am already using
font-lock-mode. It is enabled, and I cannot get highlighting.
Description such as "Use Font lock mode, if enabled, to highlight
REGEXP." with its "REGEXP" relates to the argument REGEXP. It is
related to the function. It tells little how is that supposed to work.
I have followed the above instructions by my (mis)understanding and
have specified `font-lock-specified-p' below, and after sorting I
still cannot invoke highlight-regexp neither with M-x neither by
evaluation.
Please, help me resolve this.
(define-derived-mode hyperscope-list-mode tabulated-list-mode "Hyperscope" "Hyperscope mode"
(hyperscope-text-scale-adjust 'hyperscope-list-mode)
(let ((id-length (length (number-to-string (rcd-sql-first "SELECT hyobjects_id FROM hyobjects ORDER BY hyobjects_id DESC LIMIT 1" hs-db)))))
(setq tabulated-list-format (vconcat (list (list "ID" id-length t :right-align t))
(list (list "Hyperdocument" 70 t))
(list (list "Type" 12 t))
(list (list "Action" 9 t))))
(setq font-lock-specified-p t)
(setq tabulated-list-padding 1)
;; (setq tabulated-list-sort-key (cons "ID" nil))
(tabulated-list-init-header)))

I think you just have to reapply the highlight-regexp after altering the
buffer.

Then I wasn't clear. I have tried that in first place and it does not
work. That is why I said it is bug.
I don't get it why it is not bug.

You are right, that doesn't work. The second time `hi-lock-set-pattern'
checks `hi-lock-interactive-patterns', finds the pattern, and does
nothing.
At least in the package-list buffer. Dired is different because it
_does_ use font-lock. But I don't see a problem in dired when I revert
or reorder the buffer, the highlighting doesn't disappear, so I don't
need to add a pattern a second time.
Michael.
