Re: Integration of RefTeX and LaTeX export

[Andreas Willig <andreas.willig@canterbury.ac.nz>]

Hi Thomas,

thanks for this hint. I have looked at this, the changed / added functions are
below, everything else has not changed. I still have a problem.

I have created a new link type as you suggested and have consulted google
on how to do it (my emacs-lisp-fu is not good enough to sort out directly what
this function is doing ...). In my understanding the third argument is a function
that is called when an export process has started and a link is about to be
exported. My first problem is: this handler function is never called, the error
message that i have inserted below does never appear. I have seen that the
variable "org-link-types" contains the defined link type, and the variable
"org-link-protocols" shows my handler.

My second problem is that the generated LaTeX output is
  "\texttt{\cite{key}}"
but it should simply be "\cite{key}". I would guess that the second problem
is a corollary of the first one ...

Any ideas?

Andreas

(org-add-link-type "rtcite" 
		   'rt-handler
		   (lambda (path desc format)
		     (error "my handler is called")
		     (cond ((eq format 'latex)
			    (if (or (not desc) (equal 0 (search "rtcite:" desc)))
				(format "\\cite{%s}" path)
			      (format "\\cite[%s]{%s}" desc path))))))


(defun org-mode-reftex-setup ()
  (load-library "reftex")
  (and (buffer-file-name) (file-exists-p (buffer-file-name))
       (progn
	 ;;enable auto-revert-mode to update reftex when bibtex file changes on disk
	 (global-auto-revert-mode t)
	 (reftex-parse-all)
	 ;;add a custom reftex cite format to insert links
	 (reftex-set-cite-format "[[rtcite:%l][\\cite{%l}]]")
	 ))
  (define-key org-mode-map (kbd "C-c )") 'reftex-citation)
  (define-key org-mode-map (kbd "C-c (") 'org-mode-reftex-search))
