Hi all,
The LaTeX command \autoref{} produces a hyperlink that covers both the target type and its number; for example, \autoref{chap:org} produces something like _Chapter 3_. It's very similar to Chapter \ref{chap:org}, but:
* "Chapter" is clickable
* I can demote this chapter to a section, or change a figure into a tale, and the word "Chapter" or "Figure" will appropriately change.
I'd like to use this facility in my org-mode documents. I started defining a new link type [[autoref:(1)][(2)]]; (1) is the actual link, and (2) is the text to use in HTML export (Figure, Section, ...); LaTeX export ignores it (this isn't ideal, because in the buffer it only shows Figure, section, etc.; bu since the follow function of custom links only gets the path, I didn't find another way).
This mostly worked:
(org-add-link-type "autoref" #'org-autoref-follow #'org-autoref-export)
(defun org-autoref-follow (path)
"Follow fuzzy link PATH."
(unless (run-hook-with-args-until-success
'org-open-link-functions path)
(let ((destination (org-with-wide-buffer
(org-link-search path (point)) ;; should be +2 of beginning
(point))))
(unless (and (<= (point-min) destination)
(>= (point-max) destination))
(widen))
(goto-char destination))))
but then I started looking at org-autoref-export, and things got hairy. org-latex-link gets three arguments (link desc info), which it uses in the fuzzy link case to call (org-export-resolve-fuzzy-link link info). But custom links don't get quite as much info: they just get the path, and not the `info' parameter. I wasn't sure how to proceed at that point, so I wrote my function as :around advice on org-latex-link; which is not too satisfactory.
Did I miss something?
Thanks!
Clément.

Hi Clément,
I don’t know if you’ve found a satisfactory solution yet, but I found the following to work quite well in my case:
;; Define an export function for autoref links
(defun kk/org-autoref-export (path desc format)
"Export an autoref type reference for the given path"
(case format
('latex (string-join `("\\autoref{" ,path "}")))))
;; Define a function for following org links
(defun kk/org-follow-path (path)
"Follow an org path given in the argument"
(org-open-link-from-string (string-join `("[[" ,path "]]"))))
;; Register autoref link type
(org-add-link-type "ar" 'kk/org-follow-path 'kk/org-autoref-export)
It works fine for items that have a #+NAME attached to them, perhaps to other stuff as well (though I haven’t tested this).
Hope it helps.
Good luck,
Kosta
