How do I define the space allocated to the footnotes in an Org file that is intended to be exported as a Beamer presentation? The problematic result is shown below:
The relevant bit of Org file looks like this:
#+STARTUP: beamer
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [bigger]
#+BEAMER_FRAME_LEVEL: 2
#+COLUMNS: %40ITEM %10BEAMER_env(Env) %9BEAMER_envargs(Env Args) %4BEAMER_col(Col) %10BEAMER_extra(Extra)
* Role of Org-Babel
** Overview :B_verse:
:PROPERTIES:
:BEAMER_env: verse
:END:
=org-babel= is a facility that provides inline code evaluation,
highlighting and tangling[fn:1: Tangling and untangling is the
process employed in literate programming for hiding and displaying
code blocks.].
PS. Of course literate programming.
Add the following option in your header:
#+LaTeX_HEADER:\addtobeamertemplate{footnote}{}{\vspace{2ex}}

I'm currently trying to write up my thesis in emacs org-mode, and have run into some problems with file inclusions.
When I include figures with:
#+NAME: fig:banana
#+CAPTION: this is a figure caption
[[/path/to/image.png]]
(or using a pdf) it works fine. But when I insert another image, it is somehow moved to the end of the file instead of being inserted where it is called.
My pdf-export process (in my ~/.emacs file) looks like this:
(setq org-latex-pdf-process
'("latexmk -pdflatex='pdflatex -interaction nonstopmode' -pdf -bibtex -f %f"))
Any ideas on how to fix this?
A friend of mine pointed me to the LaTex package placeins.
#+LATEX_HEADER: \usepackage{placeins}
* section 1
** hi!
#+TITLE: fig:banana
#+CAPTION: this is a banana figure
[[/link/to/banana.png]]
\FloatBarrier
* section 2
The FloatBarrier stops floats (figures are floats) from jumping over them. I will need to look into passing [tbh] options to figures from org mode further.
Check the org-mode manual on how to pass placement options such as [h], [t] etc. to theLaTeX compiler.
If you're not sure how to control where figures (more precisely, floats) get placed by LaTeX, please refer to any introduction.
Or do you want the figure to be placed where you include it? If so, you might not need it to be a float.
I like presentation zen, where less is more. I would like to export my org-mode files as beamer slides, but have the heading title ignored so as not to position a title at the top left of the each slide.
I can do it on a per-slide basis with:
** My slide title
:PROPERTIES:
:BEAMER_ENV: fullframe
:END:
Is there a way of applying this rule to every slide, without having to add this :PROPERTIES: section beneath every heading in my org file?
Several answers were suggested on the org mode mailing list here.
The one solution that worked for me was to put the following line at the top of my org file:
#+LATEX_HEADER: \setbeamertemplate{frametitle}{}
I use emacs org a lot to export parts of org documents to latex/pdf. I was wondering whether there is a way to promote all headings of the selected parts during the export process. For instance, suppose the file looks like this:
* Project 1
** Task 1 :export:
*** Introduction
Text text text.
*** Results
Text text text.
* Project 2
The emacs org export to latex would produce a tex file of the following structure:
\section{Project 1}
\subsection{Task 1}
\subsubsection{Introduction}
Text text text.
\subsubsection{Results}
Text text text.
But because there is not highest level in the part to be exported, it would make more sense to have the following structure:
\section{Task 1}
\subsection{Introduction}
Text text text.
\subsection{Results}
Text text text.
Or, even better:
\title{Task 1}
\maketitle
\section{Introduction}
Text text text.
\section{Results}
Text text text.
I was wondering whether anyone has an idea how to go about this? My lisp skills are unfortunately very rudimentary, seems like it should not be too hard.
Thanks!

The first behavior you describe can be achieved by adding the following to your .emacs:
;; Define a function for turning a single subtree into a top-level tree
;; (:export: headings might be located at an arbitrary nesting level,
;; so a single call to "org-promote-subtree" is not enough):
(defun org-promote-to-top-level ()
"Promote a single subtree to top-level."
(let ((cur-level (org-current-level)))
(loop repeat (/ (- cur-level 1) (org-level-increment))
do (org-promote-subtree))))
;; Define a function that applies "org-promote-to-top-level"
;; to each :export: subtree:
(defun org-export-trees-to-top-level (backend)
"Promote all subtrees tagged :export: to top-level.
BACKEND is the export back-end being used, as a symbol."
(org-map-entries 'org-promote-to-top-level "+export"))
;; Make org-mode run "org-export-subtrees-to-top-level" as part of the export
;; process:
(add-hook 'org-export-before-parsing-hook 'org-export-trees-to-top-level)
Implementing the second behavior is a bit trickier but you can use theorg-export-trees-to-top-level function as a starting point if that's what you ultimately need. I'd like to point out, however, that this will not work for files with more than one :export: subtree (unless you also come up with a way to decide which headline would become the \title in these cases).

With Beamer frames can be repeated by labeling the frame that should be repeated such as
\begin{frame}[label=framelabel]
...
\end{frame}
and then using \againframe{framelabel} at the place where that frame is to be repeated.
How can this method be used with Org-mode's Beamer export? The label can obviously be added by putting it in BEAMER_envargs such as:
* Org-mode section
:PROPERTIES:
:BEAMER_envargs: [label=questions]
:END:
But there are two problems in using \againframe via Org-mode:
\againframe is placed badly both if it is placed under an Org-mode section and if it is put directly in an Org-mode section. The problem is that in the former case is that is is placed inside a frame when it should be placed between. The problem in the latter case is that it is placed inside \frametitle.
\againframe is either swallowed by Org-mode sections or it is marked as one. Both are poor logical representations of its function.
So is there some effective way of using \againframe with Beamer or is there some other way to repeat frames with Org-mode that I have overlooked?
I have already looked at http://lists.gnu.org/archive/html/emacs-orgmode/2011-05/msg00954.html in trying to work this out.
I am running Org-mode 7.6 in Emacs 23.3.1 and I use Beamer 3.13.
The current org-mode has support for againframe. Just create a frame and add the beamer option BEAMER_env = againframe to the corresponding section. Or use C-c C-b a to insert it if you initialized the beamer mode on org-startup.
More information can be found in the org-mode documentation.
An example is available in the original proposal of the syntax:
* section
** My frame title :B_frame:
:PROPERTIES:
:BEAMER_env: frame
:END:
Some text. Some text. Some text. Some text.
Some text. Some text. Some text. Some text.
** section :B_againframe:
:PROPERTIES:
:BEAMER_env: againframe
:BEAMER_act: 2
:BEAMER_ref: *My frame title
:END:
This section will create "\againframe<2>{sec-1-2}".
** Following frame
etc.
I don't think this is currently possible. The limitation lies in the tree structure of an org document. As far as I understood from your question, the \againframe{...} command basically repeats a slide as is. In org terms, that means the original tree used to generate the slide is repeated. Since the org document format doesn't let you have any content which is not part of a tree (other than the frontmatter/header at the top of a file), I believe this is not possible. This has been discussed on the mailing list a few times, from what I understood there are no plans to implement something like this.
In standard Latex, one can use something like...
\section[short head]{A longer and more meaningful heading version for the section}
...that gives both a long and short version of a section (or other sectioning command) Thus, allowing for both meaningful sectioning 'titles' and, also, reasonable-looking running heads, TOCs, beamer navigation, etc..
Is there any way to easily achieve this in org mode? (That is without hard coding the sectioning commands in LATEX snippets and, thus, defeating most of the flexibility of changing sectioning levels and repurposing content for beamer, book, and article classes that is my reason for wanting to try orgmode, in first place?)
I tried a "workaround" that did not work. I tried editing the possible latex export classes by adding another class to org-export-latex-classes. This new class changes sectioning commands from \section{%s} to \section%s(EDIT-Fixed typo in slashes). Then I tested using [short]{longer version} in orgmode sections of the file. It worked, except it acted as if the longer version section heading was just "{" and "longer version" was body text! What is up with that?
Since version 8.0 the "org-export-latex-classes" strategy won't work anymore.
Instead, and dare I say much more elegantly, you can set the ALT_TITLE property for the heading.
See http://orgmode.org/manual/Table-of-contents.html.
The following org code:
* The Long Title of Section 1
:PROPERTIES:
:ALT_TITLE: Section 1
:END:
Lorem ipsum.
** The Long Title of Subsection 1-1
:PROPERTIES:
:ALT_TITLE: Subsection 1-1
:END:
Dolor sit amet.
will export to LaTeX as:
[...]
\section[Section 1]{The Long Title of Section 1}
\label{sec-1}
Lorem ipsum.
\subsection[Subsection 1-1]{The Long Title of Subsection 1-1}
\label{sec-1-1}
Dolor sit amet.
You had the right idea with creating your own LaTeX class. The problem lies with the way the templates are filled by the default org-fill-template function. I'm not so great with Lisp, but this this hack will do the trick. Add the following to your .emacs file:
(defun my-section (level text)
(let* ((in "") (out "")
(short-title (if (string-match "\\[.*\\]" text)
(substring text (match-beginning 0)
(match-end 0))
nil)))
(if short-title (setq text (substring text (match-end 0) -1)))
(setq in (org-fill-template
"\\section%S{%s}"
(list (cons "S" (or short-title ""))
(cons "s" (or text ""))))
out (copy-sequence "\\end{section}"))
(cons text (list in out in out))))
(add-to-list 'org-export-latex-classes
'("test"
"\\documentclass{article}"
my-section))
This declares a new latex class by adding a "test" class to the org-export-latex-classes. Here we declare, instead of the normal \\section{%s} stuff a function that takes two parameters --- the current level and the headline text --- and returns a modified cons cell. Some details of this information can be found in org-latex-export.el.
Above the adding to the list is where we actually define the function. This is honestly a hacky version, and I pulled a lot from the org-beamer-sectioning function in org-beamer.el file. This function basically searches the headline for anything that is like a LaTeX short label (i.e. [....]) removes it from the headline and sticks it before the actual section label. Right now this hack will only generate \section statements, no matter how deep the level - if you want something more intelligent like \chapter or \subsection or even unnumbered items, you'll need to do some more Lisping; again, see org-beamer.el for some help.
This bit of org-mode code
#+latex_class: test
* [short 1] this is 1 star
test
** this is a 2 star
test
*** [short 3] this is a 3 star
test
**** what happens
exports to LaTeX as (only relevant sections shown here):
\section[short 1]{ this is 1 star}
\label{sec-1}
test
\section{ this is a 2 star }
\label{sec-1-1}
test
\section[short 3]{ this is a 3 star}
\label{sec-1-1-1}
test
\section{ what happens }
\label{sec-1-1-1-1}
\end{section}
\end{section}
\end{section}
\end{section}
Although it's not a straight org-mode solution, it seems to work and can be a starting point for you. One of these days I might try to write it up properly and get it folded into the org-mode distribution.
It is possible to use the following commands in latex to define the text that should appear in the header to replace section names. But the TOC will still contain the original names.
\chaptermarks
\sectionmarks
\subsectionmarks
...
So, in org-mode you can write
* Long section title
#+LaTeX: \sectionmark{Short title}
edit: it actually doesn't work on the very page where the section name appears. On this one only, the full name is still put in the header.
