Re: [O] section subtitle in latex export

[Masataro Asai]

Nicolas,

sorry for my offending remarks in the second message. i was just a little
nervous about that unexpected behavior for me.

org latex classes can be considererd as a template. template is somewhat
similer to lambda. you wouldnt want any function to be modified by another
function which recieved it as its argument.

so if something may be inserted in the template without notice, instead it
should be better if it has more arguments. say additional %s. if only there
is two of them in the template you can add alternative title, this may be
an option. amother option is, giving altered version explicitly. which may
make it accept four templates per sectioning,
numbered,unnumbered,alternative numbered, altered unnumbered. some people,
at least not me, may want this feature.

if user can modify that behavior it would be definitrly better. well, that
may inflate the list of vars in customs, but thats another ploblem.

the reason of cancelling the alt title, the situation im in is written in
the
first message. one journal template throws an error because it does not
recognize altered titles.
maybe i can write a script which regex all alt titles out, but i wanted to
contribute to the development of org.

sorry for many typos, im currentry wrting on android.

 Obviously, not you.

  you shouldn't do things like this... The code is overwriting the
  defcustom'ed sectioning format, no one knows.

 Doing what? Would you mind giving an example of that overwriting thing?

  the best answer for this problem would be changing the structure of
  org-latex-classes

 Really?

  but I dont want to do that right now. so I just gave an option for
  alternative-heading.

 Why would you want to remove every optional title? That would break
 things like tags:not-in-toc and ALT_TITLE properties.

[O] section subtitle in latex export

[Masataro Asai]

Hi all,

I am currently writing a journal thesis in org-mode and exporting it
to a LaTeX file. It worked well until recently I have updated the
org-mode version
to the latest one.

My problem is that the specified class file for the journal fails to
interpret the subtitle
of the sectioning command e.g.) \section[subtitle]{title} . Is it
possible to turn off that subtitle?
I looked into the source code of ox-latex.el but org-latex-section tells
nothing about it.
I have also checked org-latex-classes but curiously
the sectioning format is just \\section{%s} and so on. no subtitle.

org-mode version is the latest devel in the git repository, after 8.0.2,
git commit hash is 00badf1
 and the emacs version is 23.3.1
