* How to get === on a line by itself to be a special string

I want separators like this:

===

to be treated as a special string in HTML.  This was the
case in the old exporter.

org-html-special-string-regexps is a variable defined in `ox-html.el'.
Its value is (("^-----$" . "<hr/>")
 ("---\\([^-]\\|$\\)" . "&mdash;\\1")
 ("--\\([^-]\\|$\\)" . "&mdash;\\1")
 ("^===$" . "<hr width=\"10%\"
style=\"width:10%;color:#000;background-color:#000;height:1px;border:none\"
/>")
 ("\\\\-" . "&shy;")
 ("---\\([^-]\\)" . "&mdash;\\1")
 ("--\\([^-]\\)" . "&ndash;\\1")
 ("\\.\\.\\." . "&hellip;"))

I don't want them to be interpreted as code.  I don't want
to turn off all code just to get this one thing to work.  I don't want
to do ~===~.

Does this mean some filter has to be used?

This did not work.

(add-to-list 'org-export-filter-code-functions
       (lambda (text back-end &rest _rest)
         (if (eq back-end 'html)
             (replace-regexp-in-string "^===$" "~===~" text)
           text)))

Thanks.

  There are a few solutions to your problem: a macro, a hook, a filter...

  That's because `html' back-end never returns "^===$", but
  "<code>=</code>", as "=" is a verbatim marker. Also, the output of
  a filter function will appear in the final output. I doubt that you want
  "~===~" to appear in your HTML document.
  
  Here is one solution, with a filter:
  
  #+begin_src emacs-lisp
  (defun my-rule-markup (paragraph backend info)
    (when (and (org-export-derived-backend-p backend 'html)
               (string-match "<p>\n<code>=</code>\n</p>\n*" paragraph))
      "<hr width=\"10%\" style=\"width:10%;color:#000;background-color:#000;height:1px;border:none\"/>\n\n"))
  (add-to-list 'org-export-filter-paragraph-functions 'my-rule-markup)
  #+end_src
  
  
  Regards,

    I think this restores the behavior.  Thank you.
