Recipes for presentations with beamer latex using emacs org-mode

Mi, 08/08/2012 - 19:42 — Draketo

I wrote some recipes for creating the kinds of slides I need with emacs org-mode export to beamer latex.

Update: Read ox-beamer to see how to adapt this to work with the new export engine in org-mode 0.8.

The recipes as PDF (21 slides, 247 KiB)

The org-mode sources (12.2 KiB)

Below is an html export of the org-mode file. Naturally it does not look as impressive as the real slides, but it captures all the sources, so I think it has some value.

Note: To be able to use the simple block-creation commands, you need to add #+startup: beamer to the header of your file or explicitely activate org-beamer with M-x org-beamer-mode.

«I love your presentation»:

PS: I hereby allow use of these slides under any of the licenses used by worg and/or the emacs wiki.

2.8 Math snippet

2.8.1 Code BMCOL B_block

2.8.2 Inline B_block

\( 1 + 2 = 3 \) is clear

2.8.3 As equation B_block

\[ 1 + 2 \cdot 3 = 7 \]

2.8.4 Result BMCOL B_block

2.8.5 Inline B_block

\( 1 + 2 = 3 \) is clear

2.8.6 As equation B_block

\[ 1 + 2 \cdot 3 = 7 \]

2.9 \( \LaTeX \)

2.9.1 Code BMCOL B_block

\( \LaTeX \) gives a space 
after math mode.

\LaTeX{} does it, too.

\LaTeX does not.

At the end of a sentence 
both work.
Try \LaTeX. Or try \LaTeX{}.

Only \( \LaTeX \) and \( \LaTeX{} \) 
also work with HTML export.

2.9.2 Result BMCOL B_block

\( \LaTeX \) gives a space after math mode.

\LaTeX{} does it, too.

2.10 Images with caption and label

2.10.1 B_columns

Code B_block BMCOL

#+caption: GNU Emacs icon
#+label: fig:emacs-icon
[[/usr/share/icons/hicolor/128x128/apps/emacs.png]]

This is image (\ref{fig:emacs-icon})

Result B_block BMCOL

GNU Emacs icon

This is image (emacs-icon)

2.10.2 B_ignoreheading

Autoscaled to the block width!

2.11 Examples

2.11.1 Code BMCOL B_block

: #+bla: foo
: * Example Header

Gives an example, which does not interfere with regular org-mode parsing.

#+begin_example
content
#+end_example

Gives a simpler multiline example which can interfere.

2.11.2 Result BMCOL B_block

#+bla: foo
* Example Header

Gives an example, which does not interfere with regular org-mode parsing.

content

Gives a simpler multiline example which can interfere.

3 Basic Configuration

3.1 Header

<Title>

#+startup: beamer
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [bigger]
#+AUTHOR: <empty for none, if missing: inferred>
#+DATE: <empty for none, if missing: today>
#+BEAMER_FRAME_LEVEL: 2
#+TITLE: <causes <Title> to be regular content!>

3.2 .emacs config

Put these lines into your .emacs or in a file your .emacs pulls in - i.e. via (require 'mysettings) if the other file is named mysettings.el and ends in (provide 'mysettings).

(org-babel-do-load-languages ; babel, for executing 
 'org-babel-load-languages   ; code in org-mode.
 '((sh . t)
   (emacs-lisp . t)))

(require 'org-latex) ; latex export 
(add-to-list         ; with highlighting
  'org-export-latex-packages-alist '("" "minted"))
(add-to-list 
  'org-export-latex-packages-alist '("" "color"))
(setq org-export-latex-listings 'minted)

3.3 .emacs variables

You can easily set these via M-x customize-variable.

(custom-set-variables ; in ~/.emacs, only one instance 
 '(org-export-latex-classes (quote ; in the init file!
    (("beamer" "\\documentclass{beamer}" 
        org-beamer-sectioning))))
 '(org-latex-to-pdf-process (quote 
    ((concat "pdflatex -interaction nonstopmode" 
             "-shell-escape -output-directory %o %f") 
     "bibtex $(basename %b)" 
     (concat "pdflatex -interaction nonstopmode" 
             "-shell-escape -output-directory %o %f")
     (concat "pdflatex -interaction nonstopmode" 
             "-shell-escape -output-directory %o %f")))))

(concat "…" "…") is used here to get nice, short lines. Use the concatenated string instead ("pdflatex…%f").

3.4 Required programs

3.4.1 Emacs - (gnu.org/software/emacs)

To get org-mode and edit .org files effortlessly.

emerge emacs

3.4.2 Beamer \( \LaTeX \) - (bitbucket.org/rivanvx/beamer)

To create the presentation.

emerge dev-tex/latex-beamer app-text/texlive

3.4.3 Pygments - (pygments.org)

To color the source code (with minted).

emerge dev-python/pygments
