Hi!
I have a custom function for exporting image links in org-mode (I have my
html exported to the parent folder of my .org files, and I just want to
keep one copy of the image files).
How can I get the "attr_html" of the link for a custom
org-set-link-parameters function? As far as I can tell, the :export wants a
function taking (path desc backend), and I do not know how to extract the
parent of the link from this.
Thanks in advance!
Regards,
Tarjei

One way is through a filter. In the filter function you get an info
argument that contains the information you want. I hacked this together and
it does add a tooltip to the link, but it is not elegant or obvious, and it
does not do any checking for the type of link, whether an attr exists, etc.
The gist is that it looks like you can get the parent from the parse-tree
info, and get the attr_html info from that (which is a list of strings).
Then you have to modify the "data" in the filter function which is the
html. It is easy here to just replace the <a with <a attr_html, but a more
complex transformation might require something more clever.
Maybe this is a start to get where you want.
the cite link is an org-ref link, but I think this should work on any kind
of link.
#+attr_html: title="I am a tooltip"
cite:schuett-2018-schnet
* build
:noexport:
#+BEGIN_SRC emacs-lisp
(defun ox-html-link-filter (data _backend info)
(let ((link (car (org-element-map (plist-get info :parse-tree) 'link
'identity))))
(replace-regexp-in-string "<a " (concat "<a "
(s-join " " (org-element-property
:attr_html
(org-element-property :parent link)))
" ")
data)))
(add-to-list 'org-export-filter-link-functions 'ox-html-link-filter)
(browse-url (org-html-export-to-html nil nil nil t))
#+END_SRC
