[Latex Export] Influence placement of \maketitle command

[Latex Export] Influence placement of \maketitle command

[Alexander Baier]

Hello,

I am writing a paper using llncs as the document class. I use the
=\institute= command which has to be placed _above_ the =\maketitle=
command to be considered. But exporting my document always yields a
latex file where =\maketitle= appears above =\institute=. I use
simple #+LATEX: directives to insert =\institute=.

Is there a way for me to influence the placement of =\maketitle= and
thus be able to order those commands "the right way"?

TIA for any pointers,

If \institute can be placed in the preamble, then using #+LATEX_HEADER
instead of #+LATEX is probably the way to go.

If it has to be in the document body, one way to do it is to redefine
the variable org-latex-title-command in a file-local-variable section
added to the end of your file:

# Local Variables:
# org-latex-title-command: "\\institute{Foo}\\maketitle"
# End:

Of course! Somehow I totally forgot about the LATEX_HEADER
directive. With this, everything works fine!

Oh, the title-command is a variable, that is nice.

Thank you very much,

While we are on the topic of placing "stuff": I also need to insert
citations for which I use bibtex. I use #+LATEX:
\bibliographystyle{plain} and #+LATEX: \bibliography{literatur} under my
last header for the bibliography to be placed at the very end.

I find this to be a somewhat lacking solution as moving my last subtree
would move my bibliography, too.

Is there a way to make it make it appear at the bottom of my document no
matter what?

I put it under its own heading with an :ignoreheading: tag and use the
filter that was posted on this list (today in fact):

#+begin_src org
  ,* references                                             :ignoreheading:
  \bibliographystyle{acm}
  \bibliography{papers.bib}
#+end_src

I can't find the filter you are referring to. I guess it is in the
org-ref thread?  I did not follow that thread as org-ref seems to be
a somewhat full-fledged solution including a lot of things I do not
need.  I looked through the thread but wasn't lucky to find said
filter.  Could you kindly post a link? (if that's not to much to ask)

Thanks,

I don't have a link, but I have the following in an example file (which
afaik still works fine):

--8<---------------cut here---------------start------------->8---
#+LATEX_CLASS: article

#+include: "ch1.org" 
#+include: "ch2.org" :minlevel 1 
#+include: "ch3.org" :minlevel 1 
#+include: "ch4.org" :minlevel 1 
#+include: "ch5.org" :minlevel 1 
#+include: "bib.org"

* Code                                                                                                        :noexport:

Suvayu's filter to get rid of :ignoreheading: tagged headlines - used in bib.org
#+BEGIN_SRC emacs-lisp :results silent
(defun sa-ignore-headline (contents backend info)
  "Ignore headlines with tag `ignoreheading'."
  (when (and (org-export-derived-backend-p backend 'latex 'html 'ascii)
          (string-match "\\`.*ignoreheading.*\n"
                (downcase contents)))
    (replace-match "" nil nil contents)))

(add-to-list 'org-export-filter-headline-functions 'sa-ignore-headline)

#+END_SRC
--8<---------------cut here---------------end--------------->8---

Using #+include also largely resolves your original concern I think
and is invaluable for larger files.

It was not in that thread and the email was tangentially about ignored
headlines.  I think it had to with beamer columns and generating
articles.  I'm offline currently so cannot check.

In any case, this is what I use:

  (defun esf/remove-lines-with-ignore-heading-tag (backend)
    (message "Deleting lines with ignore heading tag")
    (while (search-forward-regexp "^\\*+.*[ \t]+[a-ZA-Z0-9:]*:ignoreheading:[a-ZA-Z0-9:]*$" (point-max) t)
      (cond
       ((eq backend 'latex) (replace-match "#+latex: % \\&" ))
       ((eq backend 'html) (replace-match "#+html: <!-- \\& -->" ))
       (t (replace-match "")))))
  (add-hook 'org-export-before-processing-hook 'esf/remove-lines-with-ignore-heading-tag)

HTH,
eric

This works like charm, thanks!

And thanks to Suvayu for providing this filter in the first place!

This is also a good idea. But for now my document is small enough to
maintain it in a single org file.

Ah, well, neither did I follow that one.

Thank you for digging this up!  I, however, already applied Suvayu's
solution suggested by Nick that uses a headline filter.  I see that
your filter inserts the original headline in comments into the source
document, which might be very helpful, in case you are using this for
more than just two latex commands.
