latex (beamer) export and short title

latex (beamer) export and short title

[Andreas Leha]

Hi all,

I am having trouble to find a way to set a short title for the exported
beamer document.


Illustration:

I'd like to see
,----
| \title[short title]{long title}
`----
in the exported latex document.


The first shot
,----
|  #+TITLE: [short title]{long title}
`----
was too easy, I guess.


Overriding org's setting of \title with
,----
| #+TITLE:       long title
| #+latex_header: \title[short title]{long title}
`----
does not work either, as org's setting gets into the tex later.


What is the way to accomplish this?

Regards,
Andreas

There is no way to do this right now.

From what I've seen, \title[shorttitle]{title} is a beamerism, right?

If so, we may hack something in the next Beamer export library without
changing the LaTeX export library.

I have the impression that it's as well for other LaTeX classes, such as
article, report and book.

At least, it's so for ASMart: see

Can you send me a minimal .tex where \title[shorttitle]{title} works?

With the package you need for that?

It does not work on my machine.

The reason for me asking was indeed a beamer presentation.

Thanks for looking this up.  The short title for footlines is something
that I have used occasionally as well.

I'd be a regular user of such functionality, especially for
presentations.  But as the concept is useful in other (LaTeX-)
documents, a more general support for short titles might be appropriate,
I'd say.

It is as simple as using a filter to remove the title provided by the
template and install your own.

#+begin_src emacs-lisp
(defun ngz-enforce-my-title (contents backend info)
  ;; In LaTeX export, if I defined a title with a short title, remove
  ;; default title command provided by template, if any.
  (if (or (not (eq backend 'e-latex))
          (not (string-match "^\\\\title\\[.*\\]{.*}$" contents))
          (not (string-match "^\\\\title{.*}\n" contents)))
      contents
    (replace-match "" nil nil contents)))

(add-to-list 'org-export-filter-final-output-functions 'ngz-enforce-my-title)
#+end_src

Now you can use the following Org setup:

#+begin_src org
#+TITLE:       Long Title
#+LATEX_HEADER: \title[short title]{long title}
#+end_src

Argh...  this is why I love the new org-export.el !!  :)

thanks a lot for this, both the reminder that filters can do this and
the provided function.  For sure, it works, and I'll be a happy user of
this.

In general:
If org-mode exports 'A' which I'd rather like to be 'B', then I can convert
'A' to 'B' after the export (e.g. via a filter).  It would be easier if it
was 'B' right away.  The support for short titles in LaTeX export might
be a general enough concept to be supported right away.  I guess, at
least a few people will add the identical snippet from above to their
.emacs right now...  So, why not have the above filter included and
active by default?
But don't take this too seriously.  For me the own filter solution works
great.  I already have a filter, that strips the #+XXX keywords from the
export, where I can easily add another filter function.  And the general
need for short titles has been surprisingly low, apparently.

So, thanks again,
Andreas
