Dear list,

Org-mode offers the ability to create functions returning LaTeX results
: such occurrences are frequent with Sagemath, Maxima, Mathematica, R,
and even emacs's Calc...

Such functions can be declared has having LaTeX output, and the
resulting  =#+begin_export latex ...  #+end_export latex= block is
exported as LaTeX and end up in the PDF versin.

But such blocks seem to export *only* to LaTeX/PDF ; more specically,
they do not export to HTML nor ODT. In order to insert those results at
export, one *has* to print them *raw*. See the attached examples, and
compare PDF, HTML and ODT outputs of the enclosed zip archive
(necessary to avoid the wrath of the spam filter of my provider ;-
)...)..

Unless I am mistaken, this is the *only* way to export LaTeX exports to
HTML/ODT ; I am not aware of any option allowing to force such exports.
So a couple questions :
 * Am I mistaken ?
 * Are there more 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 export structure (or possibly to the various exporters) ?

Thanks in advance,

Can you declare the output as org so they will just be latex snippets?

I tried this :

#+property: header-args:sage :session
#+options: tex:t toc:nil author:nil
#+begin_src emacs-lisp :exports none
 ;; (customize-set-variable
 ;; 'org-latex-to-mathml-convert-command
 ;; "latexmlmath \"%i\" --presentationmathml=%o")
 (custom-set-variables
 '(org-latex-to-mathml-convert-command
 "java -jar %j -unicode -force -df %o %I")
 '(org-latex-to-mathml-jar-file
 "/usr/local/bin/mathtoweb.jar"))
#+end_src

A "normal" function call with org result...

#+name: foo
#+begin_src emacs-lisp :exports both :results org
 "Pseudo-function returning a LaTeX pseudo-result."
 "\\[\\displaystyle{\\sin\\left(\\frac{a}{b}\\right)}\\]"
#+end_src

#+RESULTS: foo
#+begin_src org
\[\displaystyle{\sin\left(\frac{a}{b}\right)}\]
#+end_src

Which exports the LaTeX *source* (uncompiled) in PDF, HTML and ODT.

I'm currently lookin into a =:post= workaround. But an option to export
=latex= blocks to selected exporters (ODT, HTML, possibly Morkdown via
pandoc).

I'll keep you posted.

This incantation worked for me:

#+name: foo
#+begin_src emacs-lisp :exports both :results drawer
  "Pseudo-function returning a LaTeX pseudo-result."
  "\\[\\displaystyle{\\sin\\left(\\frac{a}{b}\\right)}\\]"
#+end_src

#+RESULTS: foo
:results:
\[\displaystyle{\sin\left(\frac{a}{b}\right)}\]
:end:

the key is the drawer I think.

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:sage :session
#+options: tex:t toc:nil author:nil
#+begin_src emacs-lisp :exports none
 ;; (customize-set-variable
 ;; 'org-latex-to-mathml-convert-command
 ;; "latexmlmath \"%i\" --presentationmathml=%o")
 (custom-set-variables
 '(org-latex-to-mathml-convert-command
 "java -jar %j -unicode -force -df %o %I")
 '(org-latex-to-mathml-jar-file
 "/usr/local/bin/mathtoweb.jar"))
#+end_src

#+RESULTS:

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

A printing auxilliary :

#+name: printme
#+begin_src emacs-lisp :exports both :var data=()
 (if data
 (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 both :results value raw :post printme(data=*this*)
 "Pseudo-function returning a LaTeX pseudo-result."
 "\\[\\displaystyle{\\sin\\left(\\frac{a}{b}\\right)}\\]"
#+end_src

Real-life test :

#+name: gee
#+begin_src sage :exports both :results raw :post printme(data=*this*)
 a, b = var("a, b")
 R = str(LatexExpr("\\[\\displaystyle{%s}\\]"%latex(tan(a+b) == tan(a+b).trig_expand())))
 R += "\n\n"
 R += str(LatexExpr("\\[\\displaystyle{%s}\\]"%latex(tan(a-b) == 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 use caching... Exporting
LaTeX blocks to ODT/HTML would be a better solution...

Ideas ?

Yes, this works, indeed.

If I could just figure why

... and how to use it with captions, labels and cross-references.

But I still don't "get" drawers, I thonk.

Thanks a lot ! You gave me somethong to think about.

FYI as of
https://code.orgmode.org/bzg/org-mode/commit/b90b850ae8be46a1ebe7d13b05ad79869e8d1032
a LaTeX environment will "just work". i.e.

#+RESULTS:
\begin{equation*}
  \displaystyle{\sin\left(\frac{a}{b}\right)}
\end{equation*}

This is currently made use of in the new ob-julia (WIP).

"Raw" LaTeX code export to ODT always worked if =tex= (and possibly
=org-latex-to-mathml-convert-command=) were correctly set.

The problem is that "raw" output is no longer recognized as the
function result. If the function is reran, the result will be output
twice : once by the function execution and once by the "#+results:"
paragraph.

John's black magic with drawers allows to keep the link between
function and results.

HTH,
