* Filter not working (org 8.0.3)

Hello,

I have this at the top of an org file in order to put graphics in the 
margin:

#+LATEX_HEADER: \usepackage[right=2in,left=0.5in]{geometry} 
\usepackage{parskip}

#+BEGIN_SRC emacs-lisp
(defun margin-graphics (contents backend info)
   (when (eq backend 'latex)
     (replace-regexp-in-string "\\`\\\\includegraphics.+\\({.+}\\)"
"\\\\marginpar{\\\\includegraphics[width=0.9\\\\marginparwidth]\\1} " 
contents)))

(add-to-list 'org-export-filter-link-functions 'margin-graphics)
#+END_SRC

C-e lp produces a pdf document, but the filter is not applied (org 8.0.3).

Can someone show me what I'm doing wrong?

Thanks,
Roger

I think you need to tell Babel to actually execute the code (e.g.
with :exports both). You may also want to make
`org-export-filter-link-functions' local to the buffer, too.

Thanks for the reply.

Unfortunately, :exports both does not make any difference.  Looking at 
the generated LaTeX file I see that it contains:

\begin{verbatim}
(defun margin-graphics (contents backend info)
   (when (eq backend 'latex)
     (replace-regexp-in-string "\\`\\\\includegraphics.+\\({.+}\\)"
"\\\\marginpar{\\\\includegraphics[width=0.9\\\\marginparwidth]\\1} " 
contents)))

(add-to-list 'org-export-filter-link-functions 'margin-graphics)
\end{verbatim}

which seems odd.

Thanks for the help.

It is to be expected since ":exports both" is meant to leave source code
behind.

Anyway, the following works for me (I had to tweak your regexp):

--8<---------------cut here---------------start------------->8---
  #+LATEX_HEADER: \usepackage[right=2in,left=0.5in]{geometry}
  #+LATEX_HEADER: \usepackage{parskip}

  * Setup                                                                 :noexport:
  #+BEGIN_SRC emacs-lisp :exports both
  (defun margin-graphics (contents backend info)
      (when (eq backend 'latex)
        (replace-regexp-in-string "\\`\\\\includegraphics.*?\\({.+}\\)"
  "\\\\marginpar{\\\\includegraphics[width=0.9\\\\marginparwidth]\\1} "
  contents)))

  (add-to-list (make-local-variable 'org-export-filter-link-functions) 'margin-graphics)
  #+END_SRC

  * Document

  [[file:~/Documents/work/2-data/images/2-echantillonnage-1-fluctuations-fig1.png]]
--8<---------------cut here---------------end--------------->8---

I suggest to use `make-local-variable' to keep global filters list
clean.

That got rid of the verbatim output.  Thanks.

Unfortunately the replacement of \includegraphics... by \marginpar... 
still does not work:

#+CAPTION: Acicular
[[../images/acicular.eps]]

produces

\begin{figure}[htb]
\centering
\includegraphics[width=.9\linewidth]{../images/acicular.eps}
\caption{Acicular}
\end{figure}

I'm using org Emacs 24.3.1 (Org mode 8.0.3).

Please don't spend any more time on this on my account:  I'll use 
ConTeXt instead.

Cheers,
Roger

In this case, you need to remove "\\`" from your regexp.

That fixed it.

Many thanks.
