Exporting Latex fragment both rendered and verbatim

Exporting Latex fragment both rendered and verbatim

[Jarmo Hurri]

Greetings all.

I have been using Org for years, but just bumped into a very simple
thing I don't know how to achieve.

Let's say I have a Latex fragment, and to illustrate the use of Latex, I
want to
1. write that fragment in an Org file
2. export the file so that the fragment is exported both verbatim and
   rendered (by pdflatex or similar).

It is easy to export the fragment rendered as follows:

  #+BEGIN_EXPORT latex
    Here is an interesting (and true) equation: 
    \begin{equation} 
    \int uv' = uv - \int u'v \label{int}. 
    \end{equation}
    And that happens to be equation \eqref{int} on page \pageref{int}.
  #+END_EXPORT

It is easy to export it verbatim as follows:

  #+name: fragment
  #+BEGIN_SRC latex
    Here is an interesting (and true) equation: 
    \begin{equation} 
    \int uv' = uv - \int u'v \label{int}. 
    \end{equation}
    And that happens to be equation \eqref{int} on page \pageref{int}.
  #+END_SRC

But what is the correct combination of environments (src, export) and
header arguments (noweb, exports, results, ...) which allows me to only
write the fragment once and produce both effects? I have tried quite a
few.

Use this src block but add ":exports both" to the begin_src line.

Tried this before: for some weird (?) reason I am getting the verbatim
output only. And ":exports results" produces blank.

This is a beamer export with org version 9.1.6.

Hmm...

Very strange.  Attached are the org file I used to try this out and the
result of exporting to LaTeX.

And when I export your a.org to LaTeX, I get the attached tex with a
verbatim environment only:

Even the document classes are different. Now I am running org 9.1.7, by
the way, just did a git pull and all.

So this is a setup issue of some kind. Where should I begin... Our emacs
versions differ quite a bit (yours 27, mine 25). But that is not likely
to be the issue.

Ideas?

Ah, that's because I do modify the default LaTeX class for
export...  sorry!

But I see that you've sorted the problem out.

Got it: I did not have latex in my org-babel-do-load-languages.

Thanks!
