[-- Attachment #1.1: Type: text/plain, Size: 1144 bytes --] 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) ?

[-- Attachment #1: Type: text/plain, Size: 3239 bytes --] 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."

Which is problematic if you want to use caching... Exporting LaTeX blocks to ODT/HTML would be a better solution... Ideas ?

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). -- Timothy

```
"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.
