Reveal.js and Org-Reveal
Requirements and Installation
** Install Reveal.js
Download Reveal.js packages from [[https://github.com/hakimel/reveal.js/][here]].
Extract Reveal.js folders from the downloaded zip file.
If you do not wish to download reveal.js yourself and would rather get a copy from a CDN, see the section [[https://github.com/yjwen/org-reveal#set-the-location-of-revealjs][Set the location of Reveal.js]]
** Install org-reveal from MELPA
The easiest way to install org-reveal is to install package ox-reveal from MELPA.
Please refer to [[http://melpa.org/#/getting-started]] for using MELPA.
Note: It is suggested to use the [[http://orgmode.org/elpa.html][Org ELPA]] archive in pair with the ox-reveal packages. Emacs builtin Org-mode package may be out of date for MELPA's ox-reveal.
** Install org-reveal from GitHub
You can also install the latest developing version of org-reveal directly from GitHub.
Please download the latest Org-reveal package from [[https://github.com/yjwen/org-reveal][the Org-reveal GitHub page]]. Or clone the GitHub repository:
git clone https://github.com/yjwen/org-reveal.git
Copy =ox-reveal.el= to one of your Emacs's ~load-path~, and add the following statement to your =.emacs= file.
(require 'ox-reveal)
Note: It is suggested to use the Org-mode git repository in pair with the GitHub org-reveal. Please get the Org-mode git repository by:
$ git clone https://code.orgmode.org/bzg/org-mode
Follow the [[http://orgmode.org/worg/dev/org-build-system.html][online instruction]] for building and installing Org-mode.
** Set the location of Reveal.js
Org-reveal must know where Reveal.js is on your computer before exporting Org contents. The location of Reveal.js is the path to the top directory of the Reveal.js packages, the directory which contains file README.md, but not the one that contains the file reveal.js.
The default location is =./reveal.js=, relative to the Org file.
Changing =org-reveal-root= 's value will change the location globally. For example, add the following statement to your .emacs file:
(setq org-reveal-root "file:///d:/reveal.js")
IMPORTANT: the absolute path to Reveal.js should be in URL form, "file:///path_to_reveal.js", as illustrated above. By setting option =REVEAL_ROOT=, the location is only affected within the Org file.
,#+REVEAL_ROOT: file:///d:/reveal.js
Set your =REVEAL_ROOT= to the following URL to download reveal.js from a CDN instead of downloading a local copy.
,#+REVEAL_ROOT: https://cdn.jsdelivr.net/npm/reveal.js
*** Url form for file location
For example if you cloned this repository to your home directory,
this file in Mac OS X would be referred to as
"file:///Users/username/org-reveal/readme.org". This file in
Ubuntu would be "file:///home/username/org-reveal/readme.org" and
in Windows this file would be
"file:///c:/Users/username/org-reveal/readme.org". For more
detail on this standard please refer to
[[http://en.wikipedia.org/wiki/File_URI_scheme]]** First Try
To load Org-reveal, type "M-x load-library", then type "ox-reveal".
Now you can export this manual into Reveal.js presentation by typing "C-c C-e R R".
Open the generated "Readme.html" in your browser and enjoy the cool slides.
** The HLevel
Org-reveal maps each heading and its contents to one Reveal.js slide. Since Reveal.js arranges slides into a 2-dimensional matrix, Org-reveal use a HLevel value to decide whether to map headings to horizontal or vertical slides.
Headings with a deeper level are mapped to vertical slides.
HLevel's default value is 1, means only level 1 headings are arranged horizontally. Deeper headings are mapped to vertical slides below their parent level 1 heading.
*** HLevel's Effects on Slides Layout
Assume we have a simple Org file as below:, H1 , H2 ,** H2.1 ,** H2.1.1 , H3
If HLevel is 1, the default value, headings H2.1 and H2.1.1 will
be mapped to vertical slides below the slides of heading H2.
[[./images/hlevel.png]]
If HLevel is changed to 2, slides of heading H2.1 will be changed
to the main horizontal queue, and slides of heading H2.1.1 will be
a vertical slide below it.
[[./images/hlevel2.png]]*** Configure HLevel's Value
* Change variable =org-reveal-hlevel='s value to set HLevel globally.\\
For example, add the following statement to your =.emacs= file.(setq org-reveal-hlevel 2)
* Setting Org files local HLevel to option =REVEAL_HLEVEL=.,#+REVEAL_HLEVEL: 2
** Force Split
If one heading has too many things to fit into one slide, you can split the contents into multiple vertical slides manually, by inserting
,#+REVEAL: split
Now a new slide begins after =#+REVEAL= keyword.
To repeat the heading title on the split slide, please insert ~#+REVEAL: split:t~ instead.
** Select Theme
Theme is set globally throughout the whole file by setting option =REVEAL_THEME=.
Available themes can be found in ~dist/theme~ in the reveal.js directory and can be select by giving the CSS file base name (without .css extension) to =REVEAL_THEME=.
A custom theme CSS can be also set by giving its URL to ~REVEAL_THEME~.
Slide transition style is set by initialization option ~transition~ and the transition speed is set by ~transitionSpeed~ . Please refer to section [[Initialization options]] for details.
Available transitions are: default|cube|page|concave|zoom|linear|fade|none.
For an example of these settings, please check the heading part of this document. ** Set The Title Slide By default, Org-reveal generates a title slide displaying the title, the author, the Email, the date and the time-stamp of the Org document, controlled by Org's [[http://orgmode.org/org.html#Export-settings][export settings]].
To avoid a title slide, please set variable ~org-reveal-title-slide~ to ~nil~, or add ~reveal_title_slide:nil~ to ~#+OPTIONS:~ line.
To restore the default title slide, please set variable ~org-reveal-title-slide~ to ~'auto~.
*** Customize the Title Slide
There are 3 ways to customize the title slide.
1. Set variable ~org-reveal-title-slide~ to a string of HTML markups.
2. Set ~reveal_title_slide~ in the ~#+OPTIONS:~ line to a string of HTML markups.
3. Use one or more option lines ~#+REVEAL_TITLE_SLIDE:~ to specify
the HTML of the title slide.
The following escaping characters can be used to retrieve document
information:
| ~%t~ | Title |
| ~%s~ | Subtitle |
| ~%a~ | Author |
| ~%e~ | Email |
| ~%d~ | Date |
| ~%%~ | Literal % |*** Title Slide State
Using this option allows to thoroughly change the style of the title slide:
* =REVEAL_TITLE_SLIDE_STATE=: Style applied to the [[https://revealjs.com/markup/#viewport][viewport]] of title slide.
See the [[https://revealjs.com/markup/#slide-states][reveal.js documentation]]
for details.** Set Slide Background
Slide background can be set to a color, an image, a repeating image array or an iframe by setting heading properties.
*** Single Colored Background :PROPERTIES: :reveal_background: #543210 :END:
Set property =reveal_background= to either an RGB color value, or any
supported CSS color format.,*** Single Colored Background :PROPERTIES: :reveal_background: #123456 :END:
*** Single Image Background :PROPERTIES: :reveal_background: ./images/whale.jpg :reveal_background_trans: slide :END:
Set property =reveal_background= to an URL of background image.
Set property =reveal_background_trans= to =slide= to make background image
sliding rather than fading.,*** Single Image Background :PROPERTIES: :reveal_background: ./images/whale.jpg :reveal_background_trans: slide :END:
*** Repeating Image Background :PROPERTIES: :reveal_background: ./images/whale.jpg :reveal_background_size: 200px :reveal_background_repeat: repeat :reveal_background_opacity: 0.2 :END:
Resize background image by setting property
=reveal_background_size= to a number.
Set property =reveal_background_repeat= to =repeat= to repeat
image on the background, =reveal_background_opacity= for the
background opacity, which is a value of 0-1.,*** Repeating Image Background :PROPERTIES: :reveal_background: ./images/whale.jpg :reveal_background_size: 200px :reveal_background_repeat: repeat :reveal_background_opacity: 0.2 :END:
*** Iframe background :PROPERTIES: :reveal_background_iframe: https://hakim.se :reveal_background: rgb(0,0,0) :reveal_background_opacity: 0.8 :END:
When =iframe= is being used as slide background, the content of the slide will
be put inside a dedicated division. The other background options can be used to
configure this new division. The =reveal_background= supports both color and
image as a normal slide.:PROPERTIES:
:reveal_background_iframe: https://hakim.se
:reveal_background: rgb(0,0,0)
:reveal_background_opacity: 0.8
:END:*** Title Slide Background Image
To set the title slide's background image, please specify the
following options:
* =REVEAL_TITLE_SLIDE_BACKGROUND=: A URL to the background image.
* =REVEAL_TITLE_SLIDE_BACKGROUND_SIZE=: HTML size specification, e.g. ~200px~.
* =REVEAL_TITLE_SLIDE_BACKGROUND_REPEAT=: Set to ~repeat~ to repeat the image.
* =REVEAL_TITLE_SLIDE_BACKGROUND_OPACITY=: Set the background opacity.*** Table of Contents Slide Background Image
To set the (automatically generated) table of contents slide's background
image, please specify the following options:
* =REVEAL_TOC_SLIDE_BACKGROUND=: A URL to the background image.
* =REVEAL_TOC_SLIDE_BACKGROUND_SIZE=: HTML size specification, e.g. ~200px~.
* =REVEAL_TOC_SLIDE_BACKGROUND_REPEAT=: Set to ~repeat~ to repeat the image.
* =REVEAL_TOC_SLIDE_BACKGROUND_OPACITY=: Set the background opacity.*** Background for all slides
You can also configure the background for all slides in the presentation with:
* =REVEAL_DEFAULT_SLIDE_BACKGROUND=
* =REVEAL_DEFAULT_SLIDE_BACKGROUND_SIZE=
* =REVEAL_DEFAULT_SLIDE_BACKGROUND_POSITION=
* =REVEAL_DEFAULT_SLIDE_BACKGROUND_REPEAT=
* =REVEAL_DEFAULT_SLIDE_BACKGROUND_TRANSITION=
Refer to the [[https://github.com/yjwen/org-reveal#set-slide-background][Set slide background section]] for instructions on how to use each
parameter.** Slide Size
Reveal.js scales slides to best fit the display resolution, but you can also specify the desired size by settings the option tags =reveal_width= and =reveal_height=.
The scaling behavior can also be constrained by setting following options:
** Slide Numbering
To enable slide numbers, please add the following Reveal.js initial option.
,#+REVEAL_INIT_OPTIONS: slideNumber:true
Other possible choice for slide numbers are: | "h.v" | Horizontal . vertical slide number. The same as ~true~ | | "h/v" | Horizontal / vertical slide number | | "c" | Flatten slide number | | "c/t" | Flatten slide number / total slides |
** Slide Header/Footer Specify Slide header/footer globally by =#+REVEAL_SLIDE_HEADER:= and =#+REVEAL_SLIDE_FOOTER:=. The option content will be put into divisions of class =slide-header= and =slide-footer=, so you can control their appearance in custom CSS file(see [[https://github.com/rafadc/org-reveal#extra-stylesheets][Extra Stylesheets]]). By default header/footer content will only display on content slides. To show them also on the title and toc slide you can add ~reveal_global_header:t~ and ~reveal_global_footer:t~ to ~#+OPTIONS:~ line.
** Fragmented Contents
Make contents fragmented (show up one-by-one) by setting option
=ATTR_REVEAL= with property ":frag frag-style", as illustrated
below.Paragraphs can be fragmented.- Lists can
- be fragmented.Pictures, tables and many other HTML elements can be fragmented.*** Fragment Styles Available fragment styles are:
* grow
* shrink
* roll-in
* fade-out
* highlight-red
* highlight-green
* highlight-blue
* appear
Setting ~:frag t~ will use Reveal.js default fragment style, which
can be overridden by local option ~#+REVEAL_DEFAULT_FRAG_STYLE~ or
global variable ~org-reveal-default-frag-style~.*** Fragment Index Fragment sequence can be changed by assigning adding ~:frag_idx~ property to each fragmented element.
And, this paragraph shows at last.This paragraph shows secondly.This paragraph shows at first.*** List Fragments
~#+ATTR_REVEAL: :frag frag-style~ above a list defines fragment
style for the list as a whole.1. All items grow.
2. As a whole.
To define fragment styles for every list item, please enumerate
each item's style in a lisp list.
~none~ in the style list will disable fragment for the
corresponding list item.
Custom fragment sequence should also be enumerated for each list
item.An example:,#+ATTR_REVEAL: :frag (grow shrink roll-in fade-out none) :frag_idx (4 3 2 1 -)
When there is ~:frag_idx~ specified, insufficient fragment style list will be extended by its last element. So a ~:frag (appear)~ assigns each item of a list the ~appear~ fragment style.
,#+ATTR_REVEAL: :frag (appear)
Initialization options
Use ~#+REVEAL_INIT_OPTIONS~ to give JS snippet for initialize
reveal.js with different options. Check [[https://github.com/hakimel/reveal.js/#configuration][reveal.js document]] for
supported options. Check the head part of this document for an
example.
Third-Party Plugins
Reveal.js is also extensible through third-party plugins. Org-reveal
provides a customizable variable ~org-reveal-external-plugins~ for
defining available third-party plugins. This variable is an
associative list. The first element of each Assoc cell is a symbol
same as the name of the plugin and the second is either a string
specifying the location of the plugin script or a list of string in
case of multiple scripts. Each script string can have ONE optional
~%s~, which will be replaced by reveal-root. Code below is an
example.
(setq org-reveal-external-plugins '((RevealMenu . "path/to/reveal.js-menu/menu.js"))
Plugins can be specified in buffer by one or more ~#+REVEAL_EXTERNAL_PLUGINS~ options. Each option can have one or more plugin specifications of the same format as in ~org-reveal-external-plugins~. Below is an example.
,#+REVEAL_EXTERNAL_PLUGINS: (plugin1 . "ex/plugin1.js") (plugin2 . "ex/plugin2.js") ,#+REVEAL_EXTERNAL_PLUGINS: (plugin3 "ex/plugin3-1.js" "ex/plugin3-2.js")
At most one ~%s~ can be inserted into each plugin string, which will be replaced by Reveal.js root path.
** Highlight Source Code
There are two ways to highlight source code.
Use highlight.js
To Use your Emacs theme, please make sure ~htmlize.el~ is installed. Then no more setup is necessary.
Below is an example of highlighted lisp code from org-reveal.
(defun org-reveal--read-file (file) "Return the content of file" (with-temp-buffer (insert-file-contents-literally file) (buffer-string)))
If you saw odd indentation, please set variable =org-html-indent= to =nil= and export again.
*** Using highlight.js
You can also use [[https://highlightjs.org][highlight.js]], by adding ~highlight~ to the Reveal.js
plugin list.
#+BEGIN_SRC org
,#+REVEAL_PLUGINS: (highlight)
#+END_SRC
The default highlighting theme is ~zenburn.css~ brought with
Reveal.js. To use other themes, please specify the CSS file name by
~#+REVEAL_HIGHLIGHT_CSS~ or the variable ~org-reveal-highlight-css~.
The "%r" in the given CSS file name will be replaced by Reveal.js'
URL.
Reveal.js supports to enable line numbers and highlighting on
given line numbers. Please use ~:code_attribs~ to pass [[https://github.com/hakimel/reveal.js#line-numbers--highlights][the proper
attributes]] to the source code block . Below is an example.,#+ATTR_REVEAL: :code_attribs data-line-numbers='1|3' ,#+BEGIN_SRC c++ int main() { cout << "Hello" << endl; } ,#+END_SRC
** Auto-Animate To enable [[https://revealjs.com/auto-animate/][auto-animate]], please add ~data-auto-animate~ to heading's ~REVEAL_EXTRA_ATTR~ property. To force Reveal.js to match source codes across slides, please add the same ~:data_id foo~ to the ~#+ADDR_REVEAL:~ tag of the source code blocks. Example as below.
,* Heading 1
:PROPERTIES:
:REVEAL_EXTRA_ATTR: data-auto-animate
:END:
,#+ATTR_REVEAL: :data_id foo
,#+begin_src js
let index = 1
,#+end_src
,* Heading 2
:PROPERTIES:
:REVEAL_EXTRA_ATTR: data-auto-animate
:END:
,#+ATTR_REVEAL: :data_id foo
,#+begin_src js
let index = 1
let value = 2
,#+end_src** Editable Source Code It is now possible to embed code blocks in a codemirror instance in order to edit code during a presentation. At present, this capacity is turned on or off at time export using these defcustoms:
** MathJax :PROPERTIES: :CUSTOM_ID: my-heading :END:
${n! \over k!(n-k)!} = {n \choose k}$
LateX equation are rendered in native HTML5 contents.
IMPORTANT: Displaying equations requires internet connection to [[http://mathjax.org/][mathjax.org]] or local MathJax installation. For local MathJax installation, set option =REVEAL_MATHJAX_URL= to the URL pointing to the local MathJax location.
Note: Option ~reveal_mathjax~ is obsolete now. Org-reveal exports necessary MathJax configurations when there is Latex equation found.
** Preamble and Postamble
You can define preamble and postamble contents which will not be shown as slides, but will be exported into the body part of the generated HTML file, at just before and after the slide contents.
Change preamble and postamble contents globally by setting variable =org-reveal-preamble= and =org-reveal-postamble=.
Change preamble and postamble contents locally by setting options =REVEAL_PREAMBLE= and =REVEAL_POSTAMBLE=, as illustrated at the heading part of this document.
To add custom contents into HTML =
= parts, set contents to variable =org-reveal-head-preamble= or option =REVEAL_HEAD_PREAMBLE=.*** Generating Pre/Postamble by Emacs-Lisp Functions
If the contents of pre/postamble is the name of an evaluated
Emacs-Lisp function, which must accept an argument of Org-mode
info and return a string, the returned string will be taken
as pre/postamble contents.
So you can embed the Emacs-Lisp function as an Org-Babel source
block and mark it to be evaluated when exporting the document.** Prologue and Epilogue
Similar to preamble and postamble, arbitrary HTML contents can be inserted between the opening ~
Specify those contents by options ~REVEAL_PROLOGUE~ and ~REVEAL_EPILOGUE~ for one buffer, or by variable ~org-reveal-prologue~ and ~org-reveal-epilogue~ for global setup.
** Raw HTML in Slides
Besides the Org contents, you can embed raw HTML contents into slides by placing a =#+REVEAL_HTML= keyword.
The famous cat jump fail:
** Speaker Notes Reveal.js supports speaker notes, which are displayed in a separate browser window. Pressing 's' on slide's windows will pop up a window displaying the current slide, the next slide and the speaker notes on the current slide.
Org-reveal recognize texts between =#+BEGIN_NOTES= and =#+END_NOTES= as speaker notes. See the example below.
,* Heading 1 Some contents. ,#+BEGIN_NOTES Enter speaker notes here. ,#+END_NOTES
To skip exporting speaker notes, please set variable ~org-reveal-ignore-speaker-notes~ to ~t~.
Speaker notes requires the ~notes~ plug-in. If you changed default plug-in setting by specifying =#+REVEAL_PLUGINS= or by setting variable =org-reveal-plugins=, please make sure ~notes~ is in the plug-in list to enable speaker notes.
Due to a bug in Reveal.js, sometimes the speaker notes window shows only blank screens. A workaround to this issue is to put the presentation HTML file into the Reveal.js root directory and reopen it in the browser.
** Multiplexing Reveal.js supports a [[https://github.com/reveal/multiplex#multiplex-plugin][multiplexing plugin]], which allows your audience to view the slides of the presentation you are controlling on their own phone, tablet or laptop. As the master presentation navigates the slides, all client presentations will update in real time. See a demo at [[https://reveal-multiplex.glitch.me/]].
To use multiplexing, first prepare a Socket.io server by the instruction [[https://github.com/reveal/multiplex#socketio-server][here]]. Then include the following options in the org file. Contents in ~[]~ are commentary notes, not part of the options.
,#+REVEAL_MULTIPLEX_ID: [Obtained from the socket.io server. ] ,#+REVEAL_MULTIPLEX_SECRET: [Obtained from socket.io server. Gives the master control of the presentation.] ,#+REVEAL_MULTIPLEX_URL: https://reveal-multiplex.glitch.me [Location of socket.io server]
If your are using Reveal.js 3.x, an extra option is necessary for Socket.io scripts.
,#+REVEAL_MULTIPLEX_SOCKETIO_URL: http://cdnjs.cloudflare.com/ajax/libs/socket.io/0.9.10/socket.io.min.js
You must generate unique values for the =REVEAL_MULTIPLEX_ID= and =REVEAL_MULTIPLEX_SECRET= options, obtaining these from the socket.io server you are using.
If you include these options in your .org file, reveal-org will enable your .html file as the master file for multiplexing and will generate a file named in the form =[filename]_client.html= in the same directory as the client .html file. Provide your audience with a link to the client file to allow them to track your presentation on their own device.
** Extra Stylesheets and Script Sources
Set =REVEAL_EXTRA_CSS= to a stylesheet file path to load extra custom styles after loading a theme.
Set =REVEAL_EXTRA_SCRIPT_SRC= to script file path to load extra script sources. In case of multiple script files, specify each of them by one =REVEAL_EXTRA_SCRIPT_SRC= line. The specified scripts is loaded after Reveal.js initialization.
Scripts that must be loaded before Reveal.js initialization can be set by one or more =REVEAL_EXTRA_SCRIPT_BEFORE_SRC= lines.
,#+REVEAL_EXTRA_CSS: url-to-custom-stylesheet.css ,#+REVEAL_EXTRA_SCRIPT_SRC: url-to-custom-script
Same setup can be done globally by customize variables ~org-reveal-extra-css~, ~org-reveal-extra-script-src~ and ~org-reveal-extra-script-before-src~. In case of multiple script files, organize the script file names as a list.
** Select Built-In Scripts
Set option =REVEAL_PLUGINS= or variable =org-reveal-plugins= to a lisp list to select built-in scripts.
Available built-in scripts are: classList/markdown/highlight/zoom/notes/search/remotes.
Default built-ins are: classList/markdown/highlight/zoom/notes/multiplex.
The following examples select /markdown/ and /highlight/ only.
,#+REVEAL_PLUGINS: (markdown highlight)
** Extra Dependent Script
Set =REVEAL_EXTRA_JS= to the url of extra reveal.js dependent script if necessary.
,#+REVEAL_EXTRA_JS: url-to-custom-script.js
** Extra Slide Attribute
Set property =reveal_extra_attr= to headings to add any necessary attributes to slides.
** Export into Single File
By setting option =reveal_single_file= to ~t~, images and necessary Reveal.js scripts will be embedded into the exported HTML file, to make a portable HTML. Please note that remote images will /not/ be included in the single file, so presentations with remote images will still require an Internet connection.
Attention: This needs locally available reveal.js files!
,#+OPTIONS: reveal_single_file:t
When exporting into single file, functions provided by Reveal.js libraries will be disabled due to limitation, including PDF export, Markdown support, zooming, speaker notes and remote control.
Code highlight by highlight.js is also disabled. But code highlight by Emacs is not effected.
** Export Current Subtree
Use menu entry " C-c C-e R S" to export only current subtree, without the title slide and the table of content, for a quick preview of your current edition.
** Skip headings Any heading with tag ~:noexport:~ will be discarded when exporting to all backends. If you want a heading being discard when exporting to Reveal.js only, please use tag ~:noexport_reveal:~.
** Managing Table of Contents
It is well often the automatic "Table of Contents" is too large to fit into one slide. One workaround is to disable the automatic TOC and generate one manually, which can be split into multiple slides. Org-reveal provides a helper function to insert a TOC to the current org buffer. Type ~M-x org-reveal-manual-toc~ to invoke it.
To disable the automatic TOC, add =toc:nil= to =#+OPTIONS=
,#+OPTIONS: toc:nil
** Internal Links
Reveal.js supports only jump between slides, but not between elements on slides. Thus, we can only link to headlines in an Org document.
You can create links pointing to a headline's text, or its custom-id, as the examples below:
** Custom JS
To pass custom JS code to ~Reveal.initialize~, state the code by ~#+REVEAL_EXTRA_INITIAL_JS~ (multiple statements are concatenated) or by custom variable ~org-reveal-extra-initial-js~. The first appearance of ~%s~ in the script will be replaced by Reveal.js root path.
If you want to add extra code outside of the ~Reveal.initialize~ block, then ~#+REVEAL_EXTRA_SCRIPT~ can be used. The code will be inserted after closing the ~Reveal.initialize~ statement, but before the closing ~~ tag.
** Executable Source Blocks To allow live execution of code in some languages, enable the klipse plugin by setting ~org-reveal-klipsify-src~ to non-nil. Src blocks with the languages ~js~, ~clojure~, ~html~, ~python~, ~ruby~, ~scheme~, ~php~ will be executed with output shown in a console-like environment. See the source code of ~org-reveal-src-block~ for more details.
*** HTML Src Block
*** Javascript Src Block
console.log("success"); var x='string using single quote'; x
*** Perl Src Block (not klipsified)
I don't know perl!
** Properties for Sub-headings
If you want to have multiple reveal presentations in a single Org-mode file, you might want to switch from file-based properties like:
,#+REVEAL_HLEVEL: 2 ,#+REVEAL_INIT_OPTIONS: transition: 'cube' ,#+REVEAL_THEME: moon
to properties of sub-headings like:
:PROPERTIES: :EXPORT_REVEAL_HLEVEL: 2 :EXPORT_INIT_OPTIONS: transition: 'cube' :EXPORT_REVEAL_THEME: moon :END:
This way, each org-reveal presentation can have its own settings. An example heading with corresponding settings would look like:
,* My org-reveal presentation among many within the same Org-mode file :PROPERTIES: :reveal_overview: t :EXPORT_AUTHOR: Test Author :EXPORT_DATE: 2018-01-01 :EXPORT_TITLE: My Title :EXPORT_EMAIL: Test@example.com :EXPORT_OPTIONS: num:nil toc:nil reveal_keyboard:t reveal_overview:t :EXPORT_REVEAL_HLEVEL: 3 :EXPORT_REVEAL_MARGIN: 200 :END:
** Customize iframe background slide :PROPERTIES: :reveal_background_iframe: https://hakim.se :reveal_background: rgb(0,0,0) :reveal_background_opacity: 0.8 :reveal_background_position: absolute :reveal_extra_attr: height: 200px; bottom: -700px; border-radius: 10px; padding: 20px :END:
:reveal_background_position: absolute :reveal_extra_attr: height: 200px; bottom: -700px; border-radius: 10px; padding: 20px
