org export customization: why do #+EXCLUDE_TAGS: settings have no effect?

org export customization: why do #+EXCLUDE_TAGS: settings have no effect?

[Martin Steffen]

Hi,

I want selective export in org (for instance, exporting to beamer/latex, and
html etc). I seem to understand the "theory" but it seems not really to work
for me.


what _works_ is as follows: I set directly a corresponding variable, in
particular, for instance, set it "hard" to

(setq org-export-exclude-tags '("noexport" "private" "handout")


"noexport" is the original value, but I want to keep trees tagged as
"private" and as "handout" out of for instance the slides.

Now that seems to work.

Now: when I want to /customize/ that in the org-file itself, it seems that's
done by doing something like


#+EXCLUDE_TAGS: private


(In (older?) versions, I also found #+EXPORT_EXCLUDE_TAGS). 


Anyhow: having such a specification in the org-file seems to have /no
effect/, even if I "refresh" the org-file, nor does it work when I visit the
file for the first time. It seems simply not to affect the said variable
"org-export-exclude-tags"

I use a pretty up-to-date org version pulled from git-hub (org-version
8.3.2, emacs-version 24.3.1)

I cannot reproduce your issue. With the following buffer

  #+EXCLUDE_TAGS: private
  * H1 :private:
  * H2

I get

  1 H2
  ════

when I export to, e.g., UTF-8.

Thanks,


For your small example (exporting to latex) I get

\begin{itemize}
\item H1 :private:
\item H2
\end{itemize}

(apart from the preamble etc).  What is also weird: If I add the
``standard'' vanilla template (via C-c C-e # beamer), then

    - 1) some option settings like H:2  vs H:3 /are/ working.
    - 2) variable org-export-headline-levels does not change


By "working" I mean: if I change the #+OPTIONS: H:2 to H:3, refresh the
emacs-buffer wrt. org's settings, and export the output (concretetely I
did beamer/latex). Now changing the section-level head /does change/ the
beamer-latex output the way I'd expect (i.e., it influences the
sectioning level).

What is strange though: the emacs-variable org-export-headline-levels
does not change when doing that, expect that I would have expected that
refreshing the buffer would do exactly that: update that variable and
thereby influencing the sectioning-levels:

---------------------
org-export-headline-levels is a variable defined in `ox.el'.
Its value is 3
...
This option can also be set with the OPTIONS keyword,
e.g. "H:2".
---------------------


I did not to comprehensive experiments which #+OPTIONS work or work
strangely, I just noticed that H:3 etc ``work'' (but I don't know why),
whereas the #EXCLUDE_TAGS do ``not work'' when refreshing the
buffer. For instance in that simple example you provided.

Then something may be wrong with `org-export-headline-levels', or
`org-latex-classes' in your config.

ox-beamer uses this option item for something else,
`org-beamer-frame-level'. IOW `org-export-headline-levels' has no effect
during Beamer export.

Did you try with emacs -Q?
