Hi,

I'm trying to develop my own `publish.el` for some research project linked to reproductibility. 
I chose ox-slimhtml [0] as derived backend to limit and simplify the html/css outputs generated by vanilla html
backend/publish. 

Actually footnotes are not defined in ox-slimhtml, so as i read in the org documentation [1] ), 
i try to add this capacity by simply calling vanilla ox-html function org-html-footnote-reference into translate-alist :

(org-export-define-derived-backend 'ox-slimhtml-publish-to-html 'slimhtml
  :translate-alist '((bold . ox-slimhtml-bold)
 
                    (footnote-reference . org-html-footnote-reference)
                     (verse-block . org-html-
verse-block)
                     (special-block . org-html-special-block)))

Using the vanilla ox-html export function, everything is awesome and footnote appear in my html, normal.
 
:publishing-function org-blog-publish-to-html 

But if i switch to ":publishing-function ox-slimhtml-publish-to-html" the function 
org-html-footnote-reference is never called.

There is something i don't understand in the processing of "translate-alist", so perhaps if the derived backend doesn't
implement a footnote-reference function, i cannot extend it ?

If you have some higlight on this, or solution on this problem, i'm interested.

You didn't receive much feedback - sorry for that.

Did you make progress about your project?

The first argument of `org-export-define-derived-backend' should be the
name of the new back-end, as a symbol, not the function used to publish.
E.g,

  (org-export-define-derived-backend 'slimhtml-improved 'slimhtml
   ....)

>                     (footnote-reference . org-html-footnote-reference)

You need to define your own publishing function with the help of
`org-publish-org-to' and make it use `slimhtml-improved. Here you're
re-using plain slimhtml, without your additions. E.g.,

  (defun ox-slimhtml-improved-publish-to-html (plist filename pub-dir)
    "Publish an org file to html.
  PLIST is the property list for the given project.  FILENAME
  is the filename of the Org file to be published.  PUB-DIR is
  the publishing directory.
  Return output file name."
    (let ((html-extension (or (plist-get plist :html-extension) org-html-extension)))
      (org-publish-org-to 'slimhtml-improved
                          filename
                          (if (and html-extension (not (string= "" html-extension)))
                              (concat "." html-extension) "")
                          plist
                          pub-dir)))

Then you can set :publishing-function to `org-slimhtml-publish-to-html'.

You should be able to extend it.
