The following does what I want : export ln a = LaTeX block to latex and beamer, export as a raw LaTeX snippet in HTML and = ODT, no export otherwise :

#+property: header-args=

  (custom-set-variables

      "java -jar=
 %j -unicode -force -df %o %I")
   '(org-latex-to-mathml-jar-file=

      "/usr/local/bin/mathtoweb.jar"))
#+end_src
=


#+RESULTS:

Current exporter sr=
c_emacs-lisp[:results raw]{org-export-current-backend}.

A printing auxilliary :

#+name: printme
#+begin_src emacs-lisp :exports both :var data=3D()
  (if d=
ata
      (cond ((memq org-export-current-backend '(latex beamer)=
)
	     (format "#+begin_export latex\n%s\n#+end_export" data))
	    ((memq org-export-current-backend '(odt html))
	   =
  data)
	    (t data))
    "")
#+end_src

A "normal" function call with filtered result...
=


#+name: foo
#+begin_src emacs-lisp :exports b=
oth :results value raw :post printme(data=3D*this*)
  "Pseudo-fun=
ction returning a LaTeX pseudo-result."
  "\\[\\displaystyle{\\si=

#+end_src

<=
pre>Real-life test :

#+name: gee
#+begin=
_src sage :exports both :results raw :post printme(data=3D*this*)
  a, b =3D var("a, b")
  R =3D str(LatexExpr("\\[\\displaystyle{=

  R +=3D =
"\n\n"
  R +=3D str(LatexExpr("\\[\\displaystyle{%s}\\]"%latex(ta=
n(a-b) =3D=3D tan(a-b).trig_expand())))
  LatexExpr(R)
=
#+end_src

But this still has snags : you must not =
have evaluated results in the buffer. Which is problematic if you want to u=
se caching... Exporting LaTeX blocks to ODT/HTML would be a better solution=
...

Ideas ?

Can you declare the output as or=

Dear list,

Org-mode offers the ability to create functions retu=

Such func=

+begin_export latex ...  #+end_export latex=3D block is exported as La=
TeX and end up in the PDF versin.

But such blocks =
seem to export *only* to LaTeX/PDF ; more specically, they do n=
ot export to HTML nor ODT. In order to insert those results at export, one =
*has* to print them *raw*. See the attached examples, and com=
pare PDF, HTML and ODT outputs of the enclosed zip archive (necessary to av=
oid the wrath of the spam filter of my provider ;-)...)..

Unless I am mistaken, this is the *only* way to export LaTeX export=
s to HTML/ODT ; I am not aware of any option allowing to force such exports=
. So a couple questions :
  • Am I mistaken ?
  • Are there mo=
re steamlined ways to get LaTeX in HTML/ODF/whatever-but-not-LaTeX ?
    • Wouldn't an option to allow these exports be a welcome addition to the ex=
port structure (or possibly to the various exporters) ?
