org-export-babel-evaluate and :exports none

org-export-babel-evaluate and :exports none

[Ista Zahn]

Hi,

I upgraded to the latest git version yesterday, and am loving the new
exporter. Congrats to all involved!

However, when I set org-export-babel-evaluate to nil the new latex
exporter (I have not tried the others) ignores :exports none source
block header arguments. To reproduce:

1. start emacs with 'emacs -q' and visit a file named tmp.org with the
following contents:
<start org example>

#+TITLE: Source block export test

* Source block export

#+name: test
#+begin_src emacs-lisp :exports none :results silent :tangle no
  ;should not be exported but is
    (setq org-export-babel-evaluate nil)
#+end_src

</end org example>

2. place the point inside the test block and press 'C-c-c' to evaluate it
3. export to latex file with 'C-e l l'

the resulting tmp.tex incorrectly contains

\begin{verbatim}
;should not be exported but is
  (setq org-export-babel-evaluate nil)
\end{verbatim}

If this is an error on my part please correct my examples! Otherwise
please consider this a bug report. 'M-x org-version' reports "Org-mode
version 7.9.3e (7.9.3e-1107-g45442f @
/usr/share/emacs/site-lisp/org/)" on my system, which I believe to be
the latest.

Best,
Ista

Hi all,

Just checking to see if anyone was able to reproduce this or if I am
the only one with this problem.

Thanks,

I just make update2'ed, followed your recipe, but my tmp.tex did not
incorrectly have the exported source block.  So, I guess I can't
reproduce, unfortunately.

Thanks for checking Jay. I just tried with make update2 (usually I use
make update), with the same result as I got before (i.e., the code
block is exported). Just to make sure -- you ran the test with emacs
-q right?

Anybody else try this?
Thanks!

I confirm the problem. It is coming from
12d592b73223f3b0628e10f0f627447b1a312203. I reverted it.

Thanks you.

I confirm it is now working as expected. Thank you!

Doesn't this throw the baby out with the bathtub?  If anything that's an
indication that the evaluation and the exporting of a block should be
independently controllable.  So either org-babel-exp-process-buffer is
not the correct function to call or it needs to take
org-export-babel-evaluate into account.

BTW, the function org-export-execute-babel-code is called before it is
being defined.  Not sure why this doesn't give a warning.

I'm just starting over because that wasn't a correct solution. I'm not
even sure about what bug this patch fixed.

Anyway, it isn't org-export-babel-evaluate's job to tell when to
evaluate a source code block. It may be org-babel-exp-process-buffer's.
I asked the author of that patch to provide more information about the
context so I can get a clue.

Why should it? It's not a macro, after all.

The bug was that Babel blocks were evaluated during export when
org-export-babel-evaluate was explicitly set to nil (the default value
is t).

The documentation says that its job is exactly that, if the context is
export.

--8<---------------cut here---------------start------------->8---
Documentation:
Switch controlling code evaluation during export.
When set to nil no code will be evaluated as part of the export
process.
--8<---------------cut here---------------end--------------->8---

You call org-export-execute-babel-code however, which doesn't check the
above variable.

Ah yes.  To much C++ the last month.

FWIW, I have not experienced this bug. I always set
org-export-babel-evaluate to nil, and this has always had the desired
effect of preventing babel evaluation on export.

AFAICT, they aren't.

Try the following in a buffer with `org-export-babel-evaluate' set
alternatively to nil and t:

  #+BEGIN_SRC emacs-lisp :exports both :results value
  (+ 2 2)
  #+END_SRC

That was a typo. I meant "it isn't org-export-execute-babel-code's job
...".

It doesn't need to. Export = "ox.el", but export + babel = "ob-exp.el".
So everything Babel related should happen there.

So, /if there's a bug/, it should be fixed in ob-exp.el (maybe in
`org-babel-exp-process-buffer's'), not in ox.el.

So let's go back to the OP (Gregor Kappler, IIRC) and ask for a
reproducible recipe.
