• Overview

#+begin_export html

** Description

Welcome to Org Beamer reference card. It contains the reference documentation that describes how to write presentations based on:

• [[http://orgmode.org/][Org mode]] 9 and
• the [[https://bitbucket.org/rivanvx/beamer/][LaTeX Beamer class]].

Those free tools allow you to easily produce high quality PDF files which are going to be displayed on /every/ computer exactly the way they looked on /your/ computer.

** Features

Since they are like any other Org mode document, authoring presentations with Org Beamer is very easy, thanks to its straightforward syntax.

The obvious advantages of this approach are that:

• you don't have to know LaTeX in order to create Beamer presentations.

• you are more productive when editing presentations:

  • you can expand and collapse slides,
  • you can switch quickly between slides by using navigation (speed) commands,
  • you can incorporate code blocks (in R or in many other languages) for illustration, and evaluate them to actually render output (including plots).

** Requirements :PROPERTIES: :ID: c4f6745b-2147-4538-bd96-9f8e1e1d4669 :END:

• A working LaTeX installation is required for exporting to PDF. If it is not yet installed on your system, install [[http://www.tug.org/texlive/][TeX Live]] (for example).

• You must define a ~beamer~ class in ~org-latex-export-classes~:

  #+begin_src emacs-lisp (eval-after-load "ox-latex"

  ;; update the list of LaTeX classes and associated header (encoding, etc.) ;; and structure '(add-to-list 'org-latex-classes `("beamer" ,(concat "\documentclass[presentation]{beamer}\n" "[DEFAULT-PACKAGES]" "[PACKAGES]" "[EXTRA]\n") ("\section{%s}" . "\section*{%s}") ("\subsection{%s}" . "\subsection*{%s}") ("\subsubsection{%s}" . "\subsubsection*{%s}")))) #+end_src

• For nice code blocks, use Listings instead of Verbatim:

  #+begin_src emacs-lisp (setq org-latex-listings t) #+end_src

• Authoring presentations

** Creating a title page :PROPERTIES: :BEAMER_opt: allowframebreaks,label= :END:

The very first slide (called frame in a Beamer presentation) is the title page. By default, it will automatically be displayed with the following elements:

• the document title

  #+begin_src org ,#+TITLE: Document title #+end_src

  (file name, if none specified -- could be removed in the future)

• the author(s)'s name

  #+begin_src org ,#+AUTHOR: John Doe #+end_src

  (Emacs Lisp variable ~user-full-name~, if none specified)

• a date

  #+begin_src org ,#+DATE: 2017-01-01 #+end_src

  (LaTeX macro ~\today~, if none specified)

The insertion of ~\author~ can be turned off with:

#+begin_src org ,#+OPTIONS: author:nil #+end_src

#+beamer: \framebreak

The author's email can be included with:

#+begin_src org ,#+AUTHOR: \href{mailto:[email protected]}{John Doe} ,#+AUTHOR: \texorpdfstring{John Doe\newline\url{[email protected]}}{John Doe} % DOES NOT WORK XXX -> BEAMER_HEADER??? ,#+BEAMER_HEADER: \author{\texorpdfstring{John Doe\newline\url{[email protected]}}{John Doe}} % BAD ORDER XXX #+end_src

Other elements:

• the document subtitle,
• their affiliation (institute), and
• a title graphic can be included with the following commands:

#+begin_src org :eval no ,#+BEAMER_HEADER: \subtitle{Document subtitle} ,#+BEAMER_HEADER: \institute[INST]{Institute\\url{http://www.institute.edu}} ,#+BEAMER_HEADER: \titlegraphic{\includegraphics[height=1.5cm]{InstLogo}} #+end_src

#+begin_note

On [2015-03-21 Sat], Rasmus sent a patch to add the ~#+SUBTITLE~ keyword to

~ox-beamer~.

#+end_note

XXX Why do I have to use :eval no (in Org blocks)?

The [[id:f6d1f139-2460-4844-93f1-c71277c810e0][inner theme]] dictates how the title page is rendered.

#+begin_src org :eval no ,#+BEAMER_HEADER: \logo{\includegraphics[height=.9cm]{InstLogo}} #+end_src

** Adding an image on the title slide

Insert an image in the title slide that fills the whole width of the slide but limits to half height.

#+begin_src org :eval no ,#+BEAMER_HEADER: \titlegraphic{ \includegraphics[width=\textwidth,height=.5\textheight]{someimage} } #+end_src

(on one line.)

#+BEAMER_HEADER: \titlegraphic{\includegraphics[width=\textwidth,height=.5\textheight]{images/someimage}}

** Structure basics

Org mode presentations contain headings at different levels.

By default,

• Headings at the first outline level will become titles of the different frames.

• Deeper levels will be used as structural environments.

• The table of contents frame is created but is blank ([[id:b4252974-1d3d-4652-b42e-e7cd016f45f7][you'll understand why later]]).

  You can remove it by setting the ~toc~ option (default: ~t~) from the ~#+OPTIONS:~ keyword to ~nil~:

#+begin_src org ,#+OPTIONS: toc:nil

,* Frame 1

Some content.

,** Block

This is a block. #+end_src

** Creating a simple frame

To create a frame with bullets, you simply use standard Org mode bullets:

#+begin_src org ,* A title #+Beamer: \framesubtitle{A subtitle}

• Bullet 1
• Bullet 2
• Bullet 3 #+end_src

Content within frames is formatted using standard Org mode syntax.

The optional subtitle does not have an Org syntax because it's specific to the Beamer back-end only.

** Using graphics

How to center pictures horizontally?

• Figures

  #+ATTR_LaTeX: :width 3cm [[file:images/dot.png]]

  \pgfuseimage{myfigure}

  #+ATTR_LaTeX: :width 3cm #+CAPTION: The caption is /always/ placed below the figure. [[file:images/square.png]]

  myotherfigure

• TikZ

  http://tex.stackexchange.com/questions/64075/beamers-visible-inside-a-tikz-node

  #+begin_export latex \begin{tikzpicture} \node[align=center] {I'm {\visible<+->{very}}\happy.}; \end{tikzpicture} #+end_export

** A Little Diagram

#+BEGIN_SRC latex :file diagram.pdf :packages '(("" "tikz")) :border 1em :eval yes \usetikzlibrary{shapes,arrows} \begin{tikzpicture}[->, auto, node distance=3cm] \node [draw] (A) {A}; \node [ellipse, draw, right of=A] (B) {B}; \path (A) edge node {message} (B); \end{tikzpicture} #+END_SRC

The problem was three-fold:

• My org-latex-pdf-process was a call to latexmk that did /not/ set -outdir. This was fine for exporting a document as LaTeX as all the work happened in the one directory, but evaluating a LaTeX src block involves a temporary directory.

• The value substituted for the %o placeholder in org-latex-pdf-process included a trailing slash which prevented it from working due to a double slash appearing in constructed paths (looking at my notes, I seem to have removed this parameter because of this problem). I now set -outdir to the output of a sub-shell that pipes %o through sed to remove the trailing slash.

• I still encountered an error when evaluating the src block even though the PDF was being produced. The error was during cleanup of temporary files, specifically a .log file. The failure to delete a nonexistent file was stopping the Org machinery that would next insert the result in my document. I addressed this by changing the second parameter of the call to directory-files in the org-latex-compile function from nil to t so that it would return absolute paths.

Since making those three changes, I am able to evaluate LaTeX src blocks and have the resulting figures appear in my Org document.

** TODO Using graphics and text

Look at ~wrapfig~ or ~parinc~

** Frame with code

Here is a simple R code block...

#+begin_src org ,#+begin_src R :exports both summary(cars) ,#+end_src #+end_src

... that will display the code and show its output in the frame:

#+begin_src R :eval yes :exports both summary(cars) #+end_src

#+results: | Min. : 4.0 | Min. : 2.00 | | 1st Qu.:12.0 | 1st Qu.: 26.00 | | Median :15.0 | Median : 36.00 | | Mean :15.4 | Mean : 42.98 | | 3rd Qu.:19.0 | 3rd Qu.: 56.00 | | Max. :25.0 | Max. :120.00 |

XXX Is this needed?

#+begin_src org ,#+LATEX_HEADER: \lstdefinelanguage{R}{} #+end_src

** Frame with code only

To display a code block without evaluating it, you specify the ~:eval no~ option:

#+begin_src org ,#+begin_src R :eval no summary(cars) ,#+end_src #+end_src

It only renders the code:

#+begin_src R :eval no summary(cars) #+end_src

** Frame with output only

To display the output of a code block without echoing the underlying code, you specify the ~:exports results~ option:

#+begin_src org ,#+begin_src R :exports results summary(cars) ,#+end_src #+end_src

It only renders the results:

#+begin_src R :eval yes :exports results summary(cars) #+end_src

#+results: | Min. : 4.0 | Min. : 2.00 | | 1st Qu.:12.0 | 1st Qu.: 26.00 | | Median :15.0 | Median : 36.00 | | Mean :15.4 | Mean : 42.98 | | 3rd Qu.:19.0 | 3rd Qu.: 56.00 | | Max. :25.0 | Max. :120.00 |

** Frame with plot

Code blocks can also be used to include plots within presentations.

To display a plot while omitting the code used to generate it, you can include a code block like this:

#+begin_src org ,#+begin_src R :exports results :results graphics :file qplot.png plot(cars) ,#+end_src #+end_src

#+begin_src R :eval yes :exports results :results graphics :file qplot.png #+begin_src R :eval yes :exports results :results graphics :file qplot.png #+begin_src R :eval yes :exports results :results graphics :file qplot.png

library(ggplot2)

qplot(speed, dist, data=cars) + geom_smooth()

plot(cars) #+end_src

#+begin_center #+ATTR_LaTeX: :height 4.5cm #+results: [[file:qplot.png]] #+end_center

** Creating a table of contents :PROPERTIES: :ID: b4252974-1d3d-4652-b42e-e7cd016f45f7 :BEAMER_opt: allowframebreaks,label= :END:

If you set the ~H~ option from the ~#+OPTIONS:~ keyword (or the ~org-beamer-frame-level~ variable) to ~2~:

#+begin_src org ,#+OPTIONS: H:2 toc:t #+end_src

then:

• First-level headings become sections listed in the table of contents[fn:: The items in the TOC are clickable and take you to specific frames in the presentation.], and

• Second-level headings become the frames.

XXX Misplaced footnote!

#+beamer: \framebreak

If you set the ~H~ value to ~3~ in the ~OPTIONS~ line:

#+begin_src org ,#+OPTIONS: H:3 toc:t #+end_src

then:

• First- and second-level headings become sections and subsections listed in the table of contents, and

• Third-level headings become the frames.

In many themes, sections (and subsections, when ~H:3~) appear in the sidebar or heading.

** Present a bibliography

• Editing presentations

** Exporting to PDF

Type:

#+begin_src emacs-lisp M-x load-library RET ox-beamer RET #+end_src

to load the Beamer back-end library, and to obtain extra commands in the LaTeX export menu:

• ~C-c C-e l B~ :: Export as LaTeX buffer (Beamer).

• ~C-c C-e l b~ :: Export as LaTeX file (Beamer).

• ~C-c C-e l P~ :: Export as PDF file (Beamer).

• ~C-c C-e l O~ :: Export as PDF file and open (Beamer).

#+begin_note You do not need to set ~LaTeX_CLASS~ to ~beamer~. #+end_note

#+begin_note YYou do not need to set ~LaTeX_CLASS~ to ~beamer~. #+end_note

** Support editing

Type:

#+begin_src emacs-lisp M-x org-beamer-mode RET #+end_src

to load the minor mode ~org-beamer-mode~ easing the edition of the document structure (through the key binding ~C-c C-b~, which offers fast selection of a [[id:77f1b7a3-6e7d-4f2b-bd1f-02e6f02bba2f][Beamer environment]]).

You can also turn it on with:

#+begin_src org ,#+STARTUP: beamer #+end_src

in your document.

** Label!!!

Label to theorem.

• Distributing presentations

** Create a handout

You can distribute your presentation in the form of handouts.

Presentations exported in this manner are entirely animation-free: overlays are removed and just the last "slide" of each frame is printed.

#+begin_src org ,#+LATEX_CLASS_OPTIONS: [handout]

,#+LATEX_HEADER: \usepackage{pgfpages} ,#+LATEX_HEADER: \mode ,#+LATEX_HEADER: { ,#+LATEX_HEADER: ... see below ... ,#+LATEX_HEADER: } #+end_src

• with one frame per A4 page (extending page size)

  #+begin_src org ,#+LATEX_HEADER: \pgfpagesuselayout{resize to}[a4paper,landscape] #+end_src

• with two frames per A4 page

  #+begin_src org ,#+LATEX_HEADER: \pgfpagesuselayout{2 on 1}[a4paper,border shrink=5mm] #+end_src

• with four frames per A4 page

  #+begin_src org ,#+LATEX_HEADER: \pgfpagesuselayout{4 on 1}[a4paper,border shrink=5mm,% ,#+LATEX_HEADER: landscape] #+end_src

** Draw a border around the frames

Add a rectangle around each frame in the handout:

#+begin_src org ,#+LATEX_HEADER: \setbeamertemplate{background canvas}{ ,#+LATEX_HEADER: \tikz \draw (current page.north west) rectangle ,#+LATEX_HEADER: (current page.south east); ,#+LATEX_HEADER: } #+end_src

** Show speaker notes

Show reminders about what to say during each part of your presentation.

Your laptop monitor and your projector should have the same resolution.

** Print handout with speaker notes

See http://tex.stackexchange.com/questions/38084/displaying-slides-with-beamer-and-article-class/38146#38146

See Guido Diepen's [[http://www.guidodiepen.nl/2009/07/creating-latex-beamer-handouts-with-notes/][handoutWithNotes.sty]] for PowerPoint like handout.

#+begin_src org :eval no ,#+LATEX_HEADER: \usepackage{handoutWithNotes} ,#+LATEX_HEADER: \pgfpagesuselayout{3 on 1 with notes}[a4paper,border shrink=5mm] #+end_src

** Print as article

Using ~beamerarticle~.

• Customizing presentations

** LaTeX class (XXX not necessary, does work???)

#+begin_src org ,#+LATEX_CLASS_OPTIONS: #+end_src

Common options:

• ~8pt~, ~9pt~, ~10pt~, ~11pt~ (default), ~12pt~, ~14pt~, ~17pt~, ~20pt~
• ~draft~: no graphics, footlines,...
• ~handout~: no overlays

#+begin_src org ,#+LaTeX_CLASS_options: [bigger,allowframebreaks] #+end_src

Beamer now supports the 16:9 aspect ratio with the ~aspectratio~ option:

#+begin_src org ,#+LaTeX_CLASS_options: [aspectratio=169] #+end_src

** LaTeX preamble

Append any line of code in the LaTeX preamble with keywords specific to the LaTeX and Beamer back-ends:

#+begin_src org ,#+LATEX_HEADER: \usepackage{...} ,#+LATEX_HEADER_EXTRA: \usepackage{...} ,#+BEAMER_HEADER: \institute[short name]{Institute} #+end_src

It will go (in that order) in the ~[EXTRA]~ placeholder of the header associated to the ~beamer~ LaTeX class (see [[id:c4f6745b-2147-4538-bd96-9f8e1e1d4669][~org-latex-classes~]]).

** Inline LaTeX :PROPERTIES: :BEAMER_opt: allowframebreaks,label= :END:

You can include raw LaTeX in your Org presentations and it will get kept as LaTeX when it's exported.

*** Left :BMCOL: :PROPERTIES: :BEAMER_col: 0.43 :END:

#+begin_src org ,#+begin_export LaTeX \begin{minipage}{4cm} ... \end{minipage} ,#+end_export #+end_src

#+begin_src org ,#+LaTeX: \parbox{4cm}{...} #+end_src

Such LaTeX code will only be present in the exports to LaTeX and Beamer.

*** Right :BMCOL: :PROPERTIES: :BEAMER_col: 0.43 :END:

#+begin_src org ,#+begin_export Beamer \begin{minipage}{4cm} ... \end{minipage} ,#+end_export #+end_src

#+begin_src org ,#+Beamer: \parbox{4cm}{...} #+end_src

Such LaTeX code will only be present in the export to Beamer.

*** Back to one column :B_ignoreheading: :PROPERTIES: :BEAMER_env: ignoreheading :END:

#+beamer: \framebreak

It is especially useful for more advanced stuff like images or tables where you need more control of the LaTeX options than Org mode actually gives you.

For example, to insert a table with colspan or rowspan support:

#+begin_src org ,#+begin_export LaTeX \begin{tabular}{|l|l|l|} \hline Text1 & Text2 & Text3 \ \hline \multicolumn{3}{|c|}{Merged text here} \ \hline \end{tabular} ,#+end_export #+end_src

#+begin_center #+begin_export LaTeX \begin{tabular}{|l|l|l|} \hline Text1 & Text2 & Text3 \ \hline \multicolumn{3}{|c|}{Merged text here} \ \hline \end{tabular} #+end_export #+end_center

** Affiliated keywords

The Beamer back-end reads both

• ~#+ATTR_LATEX:~ and
• ~#+ATTR_BEAMER:~

affiliated keywords.

XXX Code with figure or table

** Using a custom theme :PROPERTIES: :ID: f6d1f139-2460-4844-93f1-c71277c810e0 :END:

You can specify a Beamer theme using the ~#+BEAMER_THEME~ keyword.

For example:

#+begin_src org :eval no ,#+BEAMER_THEME: Boadilla #+end_src

which is equivalent (for ~Boadilla~) to:

#+begin_src org :eval no ,#+BEAMER_COLOR_THEME: dolphin ,#+BEAMER_FONT_THEME: default ,#+BEAMER_INNER_THEME: [shadow]rounded ,#+BEAMER_OUTER_THEME: infolines #+end_src

** Changing the frame font

Fonts must be present on the system you're presenting on -- or it will go back to a fallback font.

Font Risque.

#+begin_src org ,#+LATEX_HEADER: \usepackage[frenchstyle]{kpfonts} #+end_src

** Changing font size for example environment

Something along these lines will work:

#+begin_src org ,#+LaTeX: {\footnotesize ... Org stuff here ... ,#+LaTeX: } #+end_src

Choose the font size you want.

You can also /shrink/ individual frames in Beamer by adding a BEAMER option property to the frame's headline. You can also specify a percentage, as in ~shrink=10~:

#+begin_src org :eval no ,* The frame title :PROPERTIES: :BEAMER_opt: shrink=10 :END: #+end_src

You can also use LaTeX ~resizebox~ to shrink table fonts:

#+LaTeX: \resizebox{\textwidth}{!}{

| 124.195 | 310.528 |

| 120.848 | 122.702 |

#+LaTeX: }

** Column view

For a column view of options and configurations for the individual frames

#+begin_src org ,#+COLUMNS: %45ITEM %10BEAMER_env(Env) %10BEAMER_act(Act) %4BEAMER_col(Col) %8BEAMER_opt(Opt) ,#+COLUMNS: %20ITEM %13BEAMER_env(Env) %6BEAMER_envargs(Args) %4BEAMER_col(Col) %7BEAMER_extra(Extra) #+end_src

• Environments

** Environment specification: BEAMER_env

XXX Put = or ~ around BEAMER_env in title...

• This becomes visible through the =B_frame= tag (visual aid only).

** Frames

*** frame :B_frame: :PROPERTIES: :BEAMER_env: frame :END:

If a heading in the current tree has a ~BEAMER_env~ property set to either ~frame~ or ~fullframe~, its level overrides the ~H~ value, giving you some flexibility in deciding what is and what isn't a frame.

#+begin_src org ,#+OPTIONS: H:2 toc:t

,* Section 1

,** Frame

,* Section 2

,** Subsection 2.1

,*** Frame :B_frame: :PROPERTIES: :BEAMER_env: frame :END:

This becomes a frame, instead of a block! #+end_src

This works in both "directions": to add or to remove sectioning levels above the current heading (which becomes a frame)!

*** fullframe :B_fullframe: :PROPERTIES: :BEAMER_env: fullframe :END:

If a heading in the current tree has a ~BEAMER_env~ property set to ~fullframe~, the frame will not display its title (~frametitle~ is being set to the empty string).

#+begin_src org ,*** Frame :B_fullframe: :PROPERTIES: :BEAMER_env: fullframe :END:

This becomes a frame, with its title ignored! #+end_src

** ~block~ environment :PROPERTIES: :ID: 77f1b7a3-6e7d-4f2b-bd1f-02e6f02bba2f :END:

Insert a default block (syntax assumes ~H:2~).

#+begin_src org ,*** A block

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. #+end_src

*** A block

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

*** End of block :B_ignoreheading: :PROPERTIES: :BEAMER_env: ignoreheading :END:

Comments:

• Use the ~BEAMER_env~ property to specify a different block type for the current "block" environment.

• Use [[id:7bf1634d-2bd6-484b-adae-67a80846cdf4][ignoreheading]] to terminate a block environment

** ~alertblock~ environment

Insert a block whose title is highlighted.

• Behaves like the ~theorem~ environment, except that the theorem style ~definition~ is used.
• In this style, the body of a ~theorem~ is typeset in an upright font.

#+begin_src org ,*** Prime number :B_definition: :PROPERTIES: :BEAMER_env: definition :END:

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. #+end_src

*** Prime number :B_definition: :PROPERTIES: :BEAMER_env: definition :END:

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

** ~example~ environment

• Behave like the ~theorem~ environment, except that the theorem style ~example~ is used.
• A side-effect of using this theorem style is that the contents is put in an ~exampleblock~ instead of a ~block~.

#+begin_src org ,*** Number 5 :B_example: :PROPERTIES: :BEAMER_env: example :END:

5 can only be divided evenly by 1 or 5, so it is a prime number. #+end_src

*** Number 5 :B_example: :PROPERTIES: :BEAMER_env: example :END:

5 can only be divided evenly by 1 or 5, so it is a prime number.

** ~theorem~ environment

• Insert a theorem.
• Italicized body.

#+begin_src org ,*** Niessen, 2010 :B_theorem: :PROPERTIES: :BEAMER_env: theorem :END:

Statement of theorem (proposition): \ Org mode + Beamer = productivity^{2} #+end_src

*** Niessen, 2010 :B_theorem: :PROPERTIES: :BEAMER_env: theorem :END:

Statement of theorem (proposition): \ Org mode + Beamer = productivity^{2}

** ~proof~ environment

• Typeset a proof.
• Period (full-stop) added at the end of the title.
• Control sequence ~\qed~ (/quod erat demonstrandum/, for the traditional "tombstone") added at the end of the proof.

#+begin_src org ,*** Proof :B_proof: :PROPERTIES: :BEAMER_env: proof :END:

Description of proof. #+end_src

*** Proof :B_proof: :PROPERTIES: :BEAMER_env: proof :END:

Description of proof.

• Quoting text

** ~quote~ environment

Use ~quote~ to typeset short quoted text (or a series of small quotes, separated by blank lines): it hasn't paragraph indentation.

#+begin_src org ,#+begin_quote "Don't give up on your dreams, keep on sleeping." --- Albert Einstein ,#+end_quote #+end_src

#+begin_quote "Don't give up on your dreams, keep on sleeping." --- Albert Einstein #+end_quote

If you want to place the source or the author's name at the right, after the quote, you can use these commands:

#+begin_src org ,#+LaTeX: \begin{raggedleft} (Albert Einstein) ,#+LaTeX: \par\end{raggedleft} #+end_src

#+LaTeX: \begin{raggedleft} (Albert Einstein) #+LaTeX: \par\end{raggedleft}

** ~quotation~ environment

Use ~quotation~ to typeset longer quoted text (one or more paragraphs) because it indents the first line of each paragraph.

#+begin_src org ,#+begin_quotation "Two things are infinite, the universe and human stupidity, and I am not yet completely sure about the universe." --- Albert Einstein ,#+end_quotation #+end_src

#+begin_quotation "Two things are infinite, the universe and human stupidity, and I am not yet completely sure about the universe." --- Albert Einstein #+end_quotation

** ~verse~ environment

Use ~verse~ for quotations where line breaks are important, such as poetry.

#+begin_src org ,#+begin_verse "Sit next to a pretty girl for an hour, it seems like a minute. Sit on a red-hot stove for a minute, it seems like an hour. That's relativity!" --- Albert Einstein ,#+end_verse #+end_src

#+begin_verse "Sit next to a pretty girl for an hour, it seems like a minute. Sit on a red-hot stove for a minute, it seems like an hour. That's relativity!" --- Albert Einstein #+end_verse

• Alternative

** Alternative environment syntax (without option)

• More readable, more portable, more natural mapping when environments exist (LaTeX + other backends): you can use special Org blocks. For example:

#+begin_src org ,#+begin_theorem There is no largest prime number. ,#+end_theorem #+end_src

You could use subsections for columns or nested structure and blocks for simple "boxes" in your frame.

• More powerful: you can't nest blocks of the same type with this syntax, and more portable when environments only exist in Beamer (then, they will appear as subheadings when exported to other backends)

• Use an empty heading /with a non-breaking space/ (or ~\phantom{dummy}~) for an empty block title.

#+begin_src org ,*** :B_theorem: :PROPERTIES: :BEAMER_env: theorem :END:

There is no largest prime number. #+end_src

If there is nothing after the block, no need to insert a heading for demarcating the end.

!Exception! The ~example~ environment can't be written in the short notation, as that one exists in Org and is translated to a ~verbatim~ LaTeX environment by default.

** Alternative environment syntax (with option)

#+begin_src org ,#+attr_latex: :options [Lagrange] ,#+begin_theorem Let $G$ be a finite group, and let $H$ be a subgroup of $G$. Then the order of $H$ divides the order of $G$. ,#+end_theorem #+end_src

#+begin_src org ,*** Lagrange :B_theorem: :PROPERTIES: :BEAMER_env: theorem :END:

Let $G$ be a finite group, and let $H$ be a subgroup of $G$. Then the order of $H$ divides the order of $G$.

,*** End of block :B_ignoreheading: :PROPERTIES: :BEAMER_env: ignoreheading :END: #+end_src

#+attr_latex: :options [Lagrange] #+begin_theorem Let $G$ be a finite group, and let $H$ be a subgroup of $G$. Then the order of $H$ divides the order of $G$. #+end_theorem

** Alternative environment syntax (with option)

#+begin_src org ,#+attr_latex: :options [Prime number] ,#+begin_definition A prime number is... ,#+end_definition #+end_src

#+begin_src org ,*** Prime number :B_definition: :PROPERTIES: :BEAMER_env: definition :END:

A prime number is...

,*** End of block :B_ignoreheading: :PROPERTIES: :BEAMER_env: ignoreheading :END: #+end_src

#+attr_latex: :options [Prime number] #+begin_definition A prime number is... #+end_definition

** Add extra environments

For simple environments, use:

#+attr_latex: :options {3}

#+begin_myenvironment

Test of a new

environment

#+end_myenvironment

I think we should changes some environment placeholders:

• Introduce %r which would stand for the raw heading (without any processing)
• %H and %U would use the raw heading text instead.

The previous definition would become:

'("textpos1" "w" "\begin{textblock}%r \visible %a {" "} \end{textblock}")

WDYT?

It never would have occurred to me on my own to use the heading text for LaTeX code. That's a conceptual leap that passed me by.

• Environment options may be given using the BEAMER_opt property. They will be enclosed in square brackets and inserted where %o appears in the environment definition. (with an example, but I can't think of one now)

• Additional arguments may be written into the environment's heading, and inserted into the LaTeX string using %r (raw heading text, no processing).

• Columns

** Column specification: BEAMER_COL

** Splitting a frame into multiple columns

To get multiple columns in a frame:

1. Press ~C-c C-b |~ (~BMCOL~) on the headings (inside the frame) which will become columns.

   The heading of column environments won't be outputted in the PDF file.

2. Specify the column width as a percentage of ~\textwidth~.

   #+begin_warning No absolute width (such as ~4cm~), which wouldn't be correctly translated... #+end_warning

Instead of ~block~, those structural environments will become ~column~ (with the width parameter as a factor of ~\textwidth~).

Consecutive ~column~ environments will be put in a ~columns~ environment.

*** First column :BMCOL: :PROPERTIES: :BEAMER_col: 0.39 :END:

First column

Two \ lines.

The arithmetic mean is equal to the summation of ~n~ numbers divided by ~n~.

*** Second column :BMCOL: :PROPERTIES: :BEAMER_col: 0.39 :END:

Second column

One line (but aligned).

$\frac{1}{n} \sum_{i=1}^{n} x_{i}$

** Splitting a frame into multiple columns

If you want to float an image to the left or right, simply include it within a 2-column layout.

*** Image :BMCOL: :PROPERTIES: :BEAMER_col: 0.39 :END:

#+ATTR_LaTeX: :width 3cm [[file:images/square.png]]

mygraphic.jpg

*** Text :BMCOL: :PROPERTIES: :BEAMER_col: 0.39 :END:

This text will appear \ to the right.

** ~column~

You can change the percent space of each column.

If you want like one column to take 70% and the other to take 30%, you can change that as follows:

XXX

** ~columns~ :B_columns: :PROPERTIES: :BEAMER_env: columns :BEAMER_opt: [c] :END:

*** Column 1 :BMCOL: :PROPERTIES: :BEAMER_col: 0.3 :END:

Colonne 1.

*** Column 2 :BMCOL: :PROPERTIES: :BEAMER_col: 0.7 :END:

Colonne 2.

** How to specify the best width?

Visualise the width by transforming the columns into blocks...

• Special cases

** appendix

You can add an appendix (frames that you do not intend to show during your talk, but which might be useful to answer a question) by inserting such a level 1 heading after the last regular slide of your actual presentation:

#+begin_src org ,* Appendix material follows :B_appendix: :PROPERTIES: :BEAMER_env: appendix :END:

Backup slides

#+end_src

Ignoring page number in backup slides can be achieved by setting the option ~noframenumbering~ on all "backup" slides.

** note

To keep your presentation notes (reminders about what to say), add a heading below the frame, and select the ~note~ environment with ~C-c C-b~.

#+begin_src org ,#+LATEX_HEADER: \setbeameroption{show notes}

,*** Some note :B_note: :PROPERTIES: :BEAMER_env: note :END:

This is a note.

• Stress this first.
• Then this. #+end_src

** noteNH

Note with its title ignored.

** againframe

You can "continue" frames that you previously started somewhere (but where certain details have been suppressed) at a much later point (for example only in the appendix) to show additional slides there.

For convenience (since those are mandatory), when asking for an ~againframe~, Org Beamer always asks for:

• ~BEAMER_ref~ property to refer, using link syntax, to (the label of) the frame being resumed, and

• ~BEAMER_act~ property to set the overlay specification.

An advantage is that you don't need to know the label of the frame being resumed: ~:BEAMER_ref: *My frame title~.

#+begin_src latex \againframe<BEAMER_act>{BEAMER_ref's name} #+end_src

Contents are ignored.

XXX How to label a frame? Via ~:BEAMER_opt: label=id~ or via other means?

** ignoreheading :PROPERTIES: :ID: 7bf1634d-2bd6-484b-adae-67a80846cdf4 :END:

Need to "close" a block environment, if followed by something else than a block.

#+begin_src org ,*** End of block :B_ignoreheading: :PROPERTIES: :BEAMER_env: ignoreheading :END: #+end_src

• A heading with an ~ignoreheading~ environment will have only its contents inserted in the output.

  • Contents is not inserted in any ~frame~ environment...

• This special value is useful to have data between frames, or to properly close a ~column~ environment.

• Animations

** Overlay specification: BEAMER_act

Set overlay / action specifications in current frame or block to create dynamic effects (/multiple slides/, called /overlays/, for a single frame) = old ~BEAMER_envargs~ property.

Overlay specifications are given inside angular brackets.

XXX <> seem to be added when they aren't present. Copied as is if present.

Headings support the ~BEAMER_act~ property:

#+begin_src org ,** Heading :PROPERTIES: :BEAMER_act: [<+->] :END:

• Item
• Item #+end_src

It is translated as:

• an overlay/action specification, or
• a default overlay specification when enclosed within square brackets.

It has an effect on all enumeration commands and all block environments inside the frame: they will be uncovered piece-wise with an incremental specification like ~<+->~.

• ~<+>~ Means that this material should appear on the next slide.
• ~<+->~ means that this appears on the next slide, and all subsequent slides.

Dynamic lists are possible on a case by case basis with the ~:overlay~ specification:

#+begin_src org ,#+ATTR_BEAMER: :overlay <+->

• Item 1
• Item 2 #+end_src

#+begin_src org

• @@beamer:<1->@@ Item 1
• @@beamer:<2->@@ Item 2 #+end_src

can be shortened to:

#+begin_src org

• @@b:<1->@@ Item 1
• @@b:<2->@@ Item 2 #+end_src

with:

#+begin_src emacs-lisp ;; export snippet translations (add-to-list 'org-export-snippet-translation-alist '("b" . "beamer")) #+end_src

• <1-| alert@1> Suppose /p/ were the largest prime number.
• <2-> Let /q/ be the product of the first /p/ numbers.
• <3-> Then /q + 1/ is not divisible by any of them.
• <1-> But /q + 1/ is greater than /1/, thus divisible by some prime number not in the first /p/ numbers.

Overlay specification for bold markup in the label of a description list:

• Test :: of a @@beamer:<2->@@useful feature!

• @@beamer:<2->@@Test 2 :: of the same feature

** Overprint

What may not be easy or possible is to use the \only directive.

You can always use the only environment. https://github.com/suvayu/.emacs.d/blob/master/org-mode-config.el#L215

That said, I think overlays with only is not as smooth as with simple overlay specifications to regular environments or macros like ~\includegraphics~, ~\item~, etc.

** Overlay specification: BEAMER_act

*** The Queen's old armchair :PROPERTIES: :BEAMER_act: <1-> :END:

• Princess Anne
• Prince Charles
• corgis

** Question on ML

#+begin_src latex \begin{figure} \begin{center} \includegraphics<1>[width=.7\textwidth]{figure1} \includegraphics<2>[width=.7\textwidth]{figure2} \includegraphics<3->[width=.7\textwidth]{figure3} \end{center} \end{figure} #+end_src

The following works for me:

#+begin_src org #+Beamer: \only<1>{ [[file:figure1.png]] #+Beamer: }\only<2>{ [[file:figure2.png]] #+Beamer: }\only<3->{ [[file:figure3.png]] #+Beamer: } #+end_src

There is the ~BEAMER_act~ property that can be used to apply overlay information on blocks but I don't think it's possible on individual figures. Of course, you could put each figure in a separate block. The following/attached will match what you had originally.

#+begin_src org #+options: H:1

• The slide ** figure 1 :PROPERTIES: :beamer_act: <1> :END: [[file:chromosome.png]] ** figure 2 :PROPERTIES: :beamer_act: <2> :END: [[file:diagram.png]] ** figure 3 :PROPERTIES: :beamer_act: <3-> :END: [[file:equation1.png]] #+end_src

• Options

** Option specification: BEAMER_opt

Insert optional arguments for the current ~frame~ or ~block~ environment using the ~BEAMER_OPT~ property.

The options will automatically be enclosed within square brackets. Don't enclose them yourself!

You can add that special property by editing the ~Opt~ column within the "column view":

1. Turn on column view by pressing ~C-c C-x C-c~ (~M-x org-columns~)
2. Go to the ~Opt~ column
3. Press ~e~ to edit its contents, and add your value
4. Exit the column editing by pressing ~q~

~fragile~ option is added automatically.

** Get the slide number

With:

#+begin_src org :PROPERTIES: :BEAMER_opt: label=name :END: #+end_src

You can set the label of a frame and then use ~\ref{name}~ to get the slide number.

** Vertical alignment :PROPERTIES: :BEAMER_opt: c :END:

You can specify /top/ vertical alignment globally by the ~t~ class option:

#+begin_src org ,#+LaTeX_CLASS_OPTIONS: [t] #+end_src

For single frames, you can use the same option locally:

#+begin_src org ,** Vertically top-aligned :PROPERTIES: :BEAMER_opt: t :END:

Some content. #+end_src

** Explicit page breaking

If the text does not fit on a single slide, all you have to do to automatically break up the frame into several frames, is set the option ~allowframebreaks~.

• To allow frame breaks on a frame by frame basis[fn:: Until the Beamer [[https://bitbucket.org/rivanvx/beamer/issue/265/including-frame-label-option-stops ][issue #265]] is solved, we need to unset the ~framelabel~ as shown above (~label=~) when we use that option.]:

  #+begin_src org :eval no ,** A very long "frame" with breaks :PROPERTIES: :BEAMER_opt: allowframebreaks,label= :END: #+end_src

  XXX This property shouldn't be interpreted for the current slide!

• You might want to put ~allowframebreaks=0.9~ there

#+beamer: \framebreak

• To add an explicit page break:

  #+begin_src org ,#+beamer: \framebreak #+end_src

• To allow frame breaks for all frames of the whole document[fn:: Till Tantau (author of Beamer) was really not keen on the idea of setting the auto-breaking frames option globally.]:

  #+begin_src org :eval no ,#+BIND: org-beamer-frame-default-options "allowframebreaks" #+end_src

** Frame without surroundings

:PROPERTIES:

:BEAMER_opt: plain

:END:

~plain~ causes the headlines, footlines, and sidebars to be suppressed. This is

useful for creating single frames with different head- and footlines or for

creating frames showing big pictures that completely fill the frame.
