Dear list,
"raw" LaTeX can already be successfully exported by some exporters :
both html and odt exporters can translate (a limited subset of) such
latex expressions in something palatable to their respective targets
(Mathjax and representation MathML respectively).
This does *not* apply to LaTeX marked as such. To be clear :
babble babble $\int_a^b f(x) dx$ noise noise
will export the math expression to html and odt (if tex:t or
tex:dvipng or tex:dvisvgm) ; on the other hand
babble babble @@latex:$\int_a^b f(x) dx$@@ noise noise
will not. Neither will :
#+latex: \[\Phi_{\mu, \sigma}(x) = \frac{e^-{\frac{(x-\mu)^2}{2\sigma^2}}}{\sigma\sqrt{2\pi}}\,.\]
nor :
#+begin_export latex
\[\Phi_{\mu, \sigma}(x) = \frac{e^-{\frac{(x-\mu)^2}{2\sigma^2}}}{\sigma\sqrt{2\pi}}\,.\]
#+end_export
This has an annoying consequence : a function cannot (easily) return a
LaTeX block. One can return a raw result, but this loses the link
between the function and its result(s).
John Kitchin has suggested
(https://lists.gnu.org/archive/html/emacs-orgmode/2021-07/msg00099.html)
to wrap raw latex code in a drawer ; this works, but I am unable to
understand how, and I do not know what are the consequences.
Having an option allowing latex code marked as such to be passed to
other exporters (possibly with conversion) would allow a "cleaner"
solution.
What do you think ?

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

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,
