Re: Suggestion : Option enabling LaTeX blocks to non-latex exporters.

[Emmanuel Charpentier]

Well... this :

#+begin_src sage :exports both :results output raw

  a, b = var("a, b");

  print("\\begin{equation*}\n%s\n\\end{equation*}"%latex(sin(a+b)==sin(a+b).trig_expand()))

  # print("\\(%s\n\\)"%latex(sin(a+b)==sin(a+b).trig_expand()))

#+end_src


#+RESULTS:

\begin{equation*}

\sin\left(a + b\right) = \cos\left(b\right) \sin\left(a\right) + \cos\left(a\right) \sin\left(b\right)

\end{equation*}

will get you the expected result, in ODT as in PDF. But this might be happenstance : the slightly simpler

#+begin_src sage :exports both :results output raw

  a, b = var("a, b");

 #  print("\\begin{equation*}\n%s\n\\end{equation*}"%latex(sin(a+b)==sin(a+b).trig_expand()))

  print("\\(%s\n\\)"%latex(sin(a+b)==sin(a+b).trig_expand()))

#+end_src


#+RESULTS:

\(\sin\left(a + b\right) = \cos\left(b\right) \sin\left(a\right) + \cos\left(a\right) \sin\left(b\right)

\)

will print the expected results *twice* (in ODT and in PDF).

The more straightforward) 

#+begin_src sage :exports both :results value latex

  var("a, b")

  latex(cos(a+b)==cos(a+b).trig_expand())

#+end_src


#+RESULTS:

#+begin_export latex

\cos\left(a + b\right) = \cos\left(a\right) \cos\left(b\right) - \sin\left(a\right) \sin\left(b\right)

#+end_export

gives the expected result in PDF (i. e. results *once*,whether the code has #+results: or not), but not in ODT.

The "Kitchin's workaround" :

#+begin_src sage :exports both :results drawer

  print("\\(\\displaystyle{%s}\\)"%latex(tan(a+b)==tan(a+b).trig_expand()))

#+end_src


#+RESULTS:

:results:

\(\displaystyle{\tan\left(a + b\right) = -\frac{\tan\left(a\right) + \tan\left(b\right)}{\tan\left(a\right) \tan\left(b\right) - 1}}\)

:end:

works as (un)expected, but is still less straightforward. I'd rather have a documented, understood way to export LaTeX snippets/ blocks marked as such explicitly exported to ODT...

Hope this is clearer,

Hi Emmanuel,

It may interest you to hear that I submitted a patch a month or two ago

(which was merged) to support LaTeX environments as results.

That means that this is now possible:

#+begin_src something

...stuff...

#+end_src

#+results:

\begin{equation*}

  some latex which will be exported nicely

\end{equation*}

All the best,

Timothy
