Hi
When I use org-mime-htmlize, then I can use the setting
Render text between "@" in red color, you can use =org-mime-html-hook=,
#+begin_src elisp
(add-hook 'org-mime-html-hook
(lambda ()
(while (re-search-forward "@\\([^@]*\\)@" nil t)
(replace-match "<span style=\"color:red\">\\1</span>"))))
#+end_src
And every text between @ appears red.
Can I have a similar setting when exporting an org file to html via the
«normal» html exporter?
Thanks
Uwe Brauer

Have a look at the filter functions, such as
`org-export-filter-final-output-functions'. See
<https://orgmode.org/manual/Advanced-Export-Configuration.html>.
All the best,
Timothy

Using a custom filter?
#+begin_src emacs-lisp
(defun foo (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-final-output-functions 'foo)
#+end_src
Best regards,
Juan Manuel

Thanks very much it works as expected. However I just realized (and this is true also for the org-mime filter that the reg-exp has a flaw.
I used the text
=email:oub@mat.ucm.es=
So there is only one @, nevertheless the exporter translated that to
<code>email:oub<span style="color:red">mat.ucm.es</code><br />
But this is wrong in my view.
Any ideas how to deal with such a situation?
Thanks
Uwe

You can bind the function to org-export-filter-plain-text-functions
instead of ...-final-output-functions.
That way you wouldn't get false positives on lines like:
=email:oub@mat.ucm.es= some text @some text@
<code>email:oub@mat.ucm.es</code> some text <span style="color:red">some text</span>
Best regards,
Juan Manuel

Perfect, thanks.
Just out of curiosity because google does not know the answer
There is
(add-hook 'some-hook 'some-function)
(remove-hook 'some-hook 'some-function)
So if I have
(add-to-list 'org-export-filter-plain-text-functions 'my-html-red)
How could I remove something from a list?
Regards
Uwe

I think this would work:
(setq org-export-filter-plain-text-functions
(remove 'my-html-red org-export-filter-plain-text-functions))
Anyway, I recommend that you take a look at the documentation on filters
that Timothy pointed you to, as custom filters are tremendously useful
and versatile, and very "surgical". I use them a lot!
You can also apply a filter only in a document, by using the #+bind
keyword and including the function in a non-exportable code block:
#+begin_src emacs-lisp :exports results :results none
(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)))
#+end_src
#+bind: org-export-filter-plain-text-functions (my-html-red)
(You need to set org-export-allow-bind-keywords to non-nil)
Best regards,
Juan Manuel
