Hello,

I'm converting a latex document into org-mode to easily export it both
to latex and html. I've just encountered something that I don't know how
to do: export a \vref reference. I would like to have something that
exports to \vref in latex, and to a normal link in html.

I thought I could do this trick with a macro:

#+macro: vref @@latex:\myvref{$1}{@@[[$1]]@@latex:}@@

then define the latex command to ignore the second argument:

\newcommand{\myvref}{2}{\vref{#1}}

Unfortunately this does not work, as the name of the label is changed
during export:

Figure \myvref{fig:log-expt-7}{\ref{fig:orgparagraph1}} 

So my question is: is anyone using vref with org-mode? Or should I just
convert this to a plain reference?

Thanks,

Alan

I may be missing something but could you not simply use

  [[vref:fig:log-expt-7]]

(along with description text if you wished) and define an org link as
below?

#+begin_src elisp
  (org-add-link-type "vref" nil
                     (lambda (path desc format)
                       (cond
                        ((eq format 'latex)
                         (format "\\vref{%s}" path)))))
#+end_src

(untested)

Thank you for the suggestion, but I end up with the same thing as with
the macro: the reference generated is to "fig:log-expt-7", but this does
not work as the label assigned by org to the figure is
"fig:orgparagraph1".

Here is a small example of a similar problem. Exporting this to latex

This is a \ref{fig:foo} and this is a link [[fig:foo]]

#+label: fig:foo
#+begin_figure
Test
#+end_figure

results in

#+begin_src latex
This is a \ref{fig:foo} and this is a link \ref{orgspecialblock1}

\begin{figure}
Test
\label{orgspecialblock1}
\end{figure}
#+end_src

Try:

(setq org-latex-prefer-user-labels t)

I think this does what you want for org 8.3.4 at least.

As a followup question, I read the documentation for `org-add-link-type`
which says "Org mode has a built-in default for exporting links." What
is the name of that function? I would like to change Eric's function to
something like:

#+begin_src elisp
  (org-add-link-type "vref" nil
                     (lambda (path desc format)
                       (cond
                        ((eq format 'latex)
                         (format "\\vref{%s}" path))
                        (t (call org default)))))
#+end_src

I searched through ox.el but could not find that function.

Thanks,

Alan

I solve this with the help of an export filter:

--8<---------------cut here---------------start------------->8---
(defun sn/ox-latex-filter-varioref (text backend info)
  (when (org-export-derived-backend-p backend 'latex)
    (replace-regexp-in-string "\\\\ref{" "\\\\vref{" text)))
    
(eval-after-load "ox-latex"
  '(progn
     (add-to-list 'org-export-filter-link-functions 'sn/ox-latex-filter-varioref)))
--8<---------------cut here---------------end--------------->8---

you could also try redefining the export of a ref link like this.

#+BEGIN_SRC emacs-lisp
(setf (elt  (assoc "ref" org-link-protocols) 2)
      (lambda (keyword desc format)
        (cond
         ((eq format 'latex)
          "\\vref{keyword}")
         ((eq format 'html)
          (format
           "<a href=\"%s\">%s</a>"
           keyword (or desc ""))))))
#+END_SRC

I am not sure if that is the kind of html export you want, but you could
adapt it to something else.

I guess these are defined in backends, e.g. org-latex-link.

Thank you for the suggestion, but this would convert every link in a
vref link. What I want to do is to be able to handle some links as vref.

Ah, yes, thanks a lot. Unfortunately this approach does not work because
org-add-link-type uses a function whose argument do not contain enough
information to call the backend functions (for instance the first
argument is a string in org-add-link-type, and it's an org link in the
backend functions).

I went back to the macro approach, and with the addition of
org-latex-prefer-user-labels it works great.

Thanks again,

Alan
