export to html, colored dates: org-mime export works but org to html does not

[Uwe Brauer <oub@mat.ucm.es>]

Hi

The following drives me a bit crazy.

I have two functions, one for email.


(defun my-color-red-html ()
  (interactive)
  (while (re-search-forward "#\\([^#]*\\)#" nil t)
    (replace-match "<span style=\"color:red\">\\1</span>")))

I put this function into  two hooks

  (add-hook 'org-mime-html-hook 'my-color-red-html)


(defun my-html-red (text backend info)
    (when (org-export-derived-backend-p backend 'html)
      (replace-regexp-in-string "#\\([^#]*\\)#"
				"<span style=\"color:red\">\\1</span>"
				text)))

  (add-to-list 'org-export-filter-plain-text-functions 'my-html-red)

Now if I have 
#<2023-02-11>#
in an email it gets replaced by 

<span style="color:red"><span class="timestamp-wrapper"><span class="timestamp"> 11.02.2023 </span></span></span>


But if I have 
#<2023-02-11>#
in an org file and export it to html, no color is added to the timestamp.

I don't know how to debug this.

Any idea?

Regards

Uwe Brauer
