org with equations, some equations are not converted when placed in a src block

[ouboub]

Hi

I found to my surprise that a src block #+begin_src latex prevents the conversion of equations. I attach the org and the odt file testmath.odt testmath.txt

[kjambunathan]

I confirm the bug. Do this as a workaround

(add-to-list  'org-src-lang-modes  '("latex" . latex))

I will fix the bug after some time ....

src blocks are pre-formatted blocks. So, you will get latex source for the equation as opposed to equation itself. You can compare the behaviour with HTML exporter.

You will get

for

* Some math with a source block

#+begin_src latex
\begin{equation}
\label{eq:test:2}
\int dx
\end{equation}
#+end_src

* With out a source block

\begin{equation}
\label{eq:test:2}
\int dx
\end{equation}

The hassle-free way to get math in libreoffice is either to use images or starmath.

You may want to consult the following articles if you want to typeset equations using starmath.

• Use Starmath---NOT LaTeX, NOT MathML---when exporting Org mode files to LibreOffice

• Mix Starmath and LaTeX / Mix English and Tamil in same Org file (or) How to conditionally export text using Macros and Drawers in Org mode

Are right, I recall having seen such a document. The documents in questions are just an interchange with students who for one reason or the other do not use LaTeX but stick to MS Word. I have to send them some formulas that involve matrices etc, and starmath, although close to say plain tex requires some time to get acquainted with. So I rather stick to latex for the moment.

Maybe the png version would be enough. How do I enable that for the odt export? Sorry for this elementary question.....

See end of this node

This method requires that the dvipng program, dvisvgm or ImageMagick suite is available on your system. You can still get this processing with

#+OPTIONS: tex:dvipng

#+OPTIONS: tex:dvisvgm

or

#+OPTIONS: tex:imagemagick

Thanks very useful, again

#+OPTIONS: tex:dvipng

Works, but the enumeration of the equation environment does not really work, all equations end up with (1)

#+OPTIONS: tex:dvisvgm

It is installed but the conversion seems not to work

or

#+OPTIONS: tex:imagemagick

Work, and I cannot distinguish the result from dvipng.

thanks

A problem! the followiing contruction is not converted to odt, but to html (with a subdirectory including the png image for the equation) maybe this has to do what you said about starmath testmath.txt

I did but it did not help.

Ok. It is not that urgent or sever.
