Dear Nicolas, Thank you for the prompt reply. Nicolas Goaziou m...@nicolasgoaziou.fr writes: Samuel Loury konubi...@gmail.com writes: This I just the feature I need today. Thank you for sharing. Do you know what is missing to add the feature to org-mode instead of adding in each user's .emacs file? This function apparently includes many features. Which one are you talking about? I used the clearpage and newpage features. The only other way I found out was to add a bit of latex just before the heading. --8---cut here---start-8--- * My heading Some content with images. @@latex:\clearpage@@ * My other heading, totally cleared some other content --8---cut here---end---8--- What I dislike with this way of doing is that the latex fragment is inside the heading above while I would prefer to associate it with the second heading. The semantic in my case is I am starting a brand new topic, clear the floats from the last topic so that they won't pollute my new topic. I find the solution with the code of Thomas S.

I used the clearpage and newpage features. The only other way I found out was to add a bit of latex just before the heading. As Nicolas says, we'd need to think carefully as to how to incorporate such things across backends for it to be worthwhile to include. For clearpage you'd have something like in ascii and there's an odt equivalent as well. For html it's less clear. New features should be implemented like headline properties. I would still like to see a proper ignoreheading, but it's a proper definition of this behavior is hard. Note: For all Tom's examples it would be enough to have a way to insert arbitrary code just before (and maybe just after) a headline. An export_before_BACKEND property, say.

The :ignoreheading: part has been discussed already on this ML (and it's a FAQ, IIRC). The major problem is that it is not clearly defined as a parse tree operation. Regards, -- Nicolas Goaziou

Aloha all,
Inspired by discussions and code on the mailing list, I managed to
cobble together the headline filter below. It works in that the
pdf output from LaTeX export is exactly what I want. I'm thrilled!
It has one unwanted side effect. In the tex file, a headline tagged
with either :newpage: or :clearpage: includes some extra baggage, like
this:
\newpage
\section*{Introduction\hfill{}\textsc{}}
\label{sec-5}
I tried setting the option tags:nil, but then my export tags had no
effect. Can someone suggest how I can avoid the \hfill etc.? Or, am I
picking nits here?

Here's an edited filter that works with the enclosed test document.
Note that you could split this into different filters, but it may be
non-trivial with this identification-scheme since things would be
moving around.
