Integration of RefTeX and LaTeX export

Integration of RefTeX and LaTeX export

[Andreas Willig]

Hi,

i am relatively new to org mode. Yesterday i have tried to use org mode for
the first time to write the beginnings of a paper, and found that i wanted to
insert literature references and a bibliography. I like RefTeX a lot and google
provided me some links for proper integration. As a result, i have added the
stuff to my .emacs that you find below. The "org-latex-to-pdf-process" stuff
works.

My problems are related to (reftex-set-cite-format ..). Right now i do not use
it and get the default implementation by which RefTeX simply expands the
chosen reference to \cite{Key}, which is not highlighted in the org buffer. I would
like to have this expanded into an org link with the [[][]] syntax. I have tried
several variations of (reftex-set-cite-format ...) but i have never succeeded in
creating the bibliography. After generating the LaTeX output into a buffer 
(C-c C-e L) i found that org translates [[][]] type of stuff into \hyperref{}s and not
into \cite{} commands.

So, how can i change things so that in the org buffer the bib key gets displayed
nicely and in the LaTeX output a \cite{} command is generated?

Any help would be appreciated!!

Best regards,

Andreas

Aloha Andreas,

Welcome to Org Mode!

You might want to define a new link type.  See
http://orgmode.org/worg/org-tutorials/org-latex-export.html#sec-17-2 for
one example of how this might be done.

Tom

Re: Integration of RefTeX and LaTeX export

[Andreas Willig]

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

============================================

(defun rt-handler (path)
  (message "dummy handler called, path = %s" path)
  (let ((arg (concat "\\cite{" path "}")))
    (reftex-view-crossref arg)))

(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}]]")
	 ))

I'm pretty sure the second function is not quoted properly in your
org-add-link-type so it ends up actually getting called at the time of
the org-add-link-type is called.

Try the following:

--8<---------------cut here---------------start------------->8---
(defun rt-follow-handler (path)
  (message "dummy handler called, path = %s" path)
  (let ((arg (concat "\\cite{" path "}")))
    (reftex-view-crossref arg)))

(defun rt-export-handler  (path desc format)
  (message "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)))))

(require 'org)
(org-add-link-type "rtcite" 
		   (function rt-follow-handler)
		   (function rt-export-handler))
--8<---------------cut here---------------end--------------->8---

By way of explanation:

I had this as part of a minimal .emacs and it seems to work more or
less OK: I replaced the error call with a message call, because it
actually triggered and blew up :-) The rt-export-handler needs tweaking
but you 'll know what to do better than I do when you see the latex
output.

I had to (require 'org) to pick up the definition of org-add-link-type:
that seems to be a missing autoload somewhere.

And finally I like to quote functions with function, not quote, for
compiled-code reasons, but in most cases, it won't make any difference:
use quotes if you prefer.

Hi Nick,

thanks for this, but i cannot get it to work ...
I have started a vanilla emacs without any init file
(emacs -q), have loaded your snippet from a file and
evaluated the buffer. Again, the export-handler does
not get called. I am running Debian 6.0.4 and my emacs
is the one coming with it (see below).

I feel so stupid :-))

Andreas


M-x emacs-version says: GNU Emacs 23.2.1 (i486-pc-linux-gnu, GTK+ Version 2.20.0) of 2010-12-12 on raven, modified by Debian

M-x org-version says: Org-mode version 6.33x

Debian version is 6.0.4 (/etc/debian_version)

I should have added that the rt-follow-hander is properly called ...

Is this a version problem?

(emacs -q), have loaded your snippet from a file and
evaluated the buffer. Again, the export-handler does
not get called. I am running Debian 6.0.4 and my emacs
is the one coming with it (see below).

I feel so stupid :-))

I'm pretty sure the second function is not quoted properly in your
org-add-link-type so it ends up actually getting called at the time of
the org-add-link-type is called.

Try the following:

--8<---------------cut here---------------start------------->8---
(defun rt-follow-handler (path)
  (message "dummy handler called, path = %s" path)
  (let ((arg (concat "\\cite{" path "}")))
    (reftex-view-crossref arg)))

(defun rt-export-handler  (path desc format)
  (message "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)))))

(require 'org)
(org-add-link-type "rtcite" 
		   (function rt-follow-handler)
		   (function rt-export-handler))
--8<---------------cut here---------------end--------------->8---

By way of explanation:

I had this as part of a minimal .emacs and it seems to work more or
less OK: I replaced the error call with a message call, because it
actually triggered and blew up :-) The rt-export-handler needs tweaking
but you 'll know what to do better than I do when you see the latex
output.

I had to (require 'org) to pick up the definition of org-add-link-type:
that seems to be a missing autoload somewhere.

And finally I like to quote functions with function, not quote, for
compiled-code reasons, but in most cases, it won't make any difference:
use quotes if you prefer.

Re: Integration of RefTeX and LaTeX export

[Andreas Willig]

Hi,

it is a version problem. I have just downloaded the latest version of
org-mode (7.8.03) and now the handler gets called. 

Sorry for the fuss ...

Thanks again, i really appreciate the quick help i have received here!!

I should have added that the rt-follow-hander is properly called ...

Is this a version problem?

Hi Nick,

thanks for this, but i cannot get it to work ...
I have started a vanilla emacs without any init file
(emacs -q), have loaded your snippet from a file and
evaluated the buffer. Again, the export-handler does
not get called. I am running Debian 6.0.4 and my emacs
is the one coming with it (see below).

So what version were you using? The only likely fix I found was this
commit from almost two years ago:

so yours must have been pre-6.36 or thereabouts, i.e. probably whatever was
built-in with your (23.2-based?) emacs.

If you were indeed using such an ancient version, I think you will be
*much* happier with latest.

No fuss, no muss.

6.33 as delivered with Emacs23, this was buried in some earlier posting...

Thanks! I found the posting and it was a reply to me: hardly buried, but
I missed it nevertheless - sorry about that.

Navigatable and exportable bib/notes links - Was: Re: Integration of RefTeX and LaTeX export

[Olivier Berger]

Hi.

FWIW, I've been inspired by your code and some other posts on the topic
of bibliographic references / notes management with org-mode and have
summarized the results in [0].

The end result : links like [[note:abibref]] or [[bib:abibref]] which
respectively point to a bibliography notes or a bibtex section in a
.bib, and which both can be exported to latex as regular \cite{abibref}
references would do.

Hope this helps.

Best regards,
