Presentation with org beamer

Presentation with org-beamer

org-mode (an emacs major mode) comes with a namespace \`ox-beamer\` which permits to export org-mode to pdf presentation using LaTeX's beamer package.

This permits using org-mode's simple markup to write presentations.

Pre-requisite

environment

We need

• emacs

• latex

• latex's beamer package

Use your distribution's package manager to install those.

emacs setup

For inria, we need access to some latex macro that org does not know by default. This macro defines a \`picblock\` entry which permits to easily embed pictures with text.

Thus we need to extend emacs's org-beamer-mode:

   (require 'ox-beamer)
   
   (add-to-list 'org-beamer-environments-extra
                '("picblock"  "P" "\\begin{picblock}%o{%h}"      "\\end{picblock}"))

inria-presentation minor mode

For convenience here is a emacs minor mode to ease creating new presentation. Kill/Yank this snippet in your emacs configuration ~/.emacs.d/init.el for it to be loaded at emacs' startup time. When you want to create a presentation with beamer: M-x org-beamer-mode RET

Default template headers

Now we need to edit org-mode buffers to setup the pdf generation.
