Exporting to LaTeX Beamer

Exporting to LaTeX Beamer

[Uwe Ziegenhagen]

Hi,

I am trying to export an org file to individual Beamer frames but fail as
Org mode exports the sections, but not the frames.

I use the following example org file (as given by
http://orgmode.org/worg/exporters/beamer/tutorial.html)

This slide consists of some text with a number of bullet points:

- the first, very @important@, point!
- the previous point shows the use of the special markup which
  translates to the Beamer specific /alert/ command for highlighting
  text.


The above list could be numbered or any other type of list and may
include sub-lists.

Use H:2 option instead of H:3 (in the #+OPTIONS line).  This setting
tells the exporter which level of heading constitutes frames.

Hi Eric, thanks for the feedback. I switched to H:2 but get no difference in
the output:

Here's the .emacs file I use:

;; Do not show welcome screen
(setq inhibit-startup-message t)

;; Load Emacs Org-Mode
(add-to-list 'load-path "C:/emacs-24.3/MyLisp/org-8.2.6/lisp/")

;; load the latex extension
(require 'ox-html)
(require 'ox-latex)
(require 'ox-ascii)
(require 'ox-beamer)


;; Load Recentfile code, see entry in  menu
(require 'recentf)
(recentf-mode 1)
(setq recentf-max-menu-items 25)
(global-set-key "\C-x\ \C-r" 'recentf-open-files)

;; show no startup-screen
(setq inhibit-startup-screen t)

;; just answer Emacs' question with 'y' or 'n'
(defalias 'yes-or-no-p 'y-or-n-p)

How exactly are you trying to export?  Your output looks like a plain
latex export (M-x org-export-dispatch RET l p), not beamer (... l P)?
Note difference in case (p versus P) and similar for export to latex
code alone (l or b) and for opening the PDF automatically (o versus O).

For beamer export, by the way, you do not need to specify the
latex_class.  For version 8.x of org, you no longer need
BEAMER_FRAME_LEVEL either.  For most of my beamer org documents, all I
have in terms of specifications is the following:

--8<---------------cut here---------------start------------->8---
#+TITLE:     The title of the talk
#+AUTHOR:    Eric S Fraga
#+LaTeX_CLASS_options: [bigger,allowframebreaks]
#+OPTIONS:   H:2 toc:nil num:nil
#+startup: beamer
--8<---------------cut here---------------end--------------->8---

followed by the actual content.  The startup option is to enable the
special key bindings that work on headlines for columns and blocks.

Also note that @...@ is no longer the specification for alterted
text.  Use *...* instead.  The example you have was for version 7.x of
org.

Finally, the documentation for the new exporter, for org v8.x, is here:
http://orgmode.org/worg/exporters/beamer/ox-beamer.html
The older documentation, written by me initially, is no longer
applicable but is there for those people still using org v7.x.

HTH,
eric

Got it! My assumption was that the LaTeX export is controlled by the beamer
startup option and just user the lowercase exports.

Now it's working, thanks for the help!
