The deck.js backend is a collection of Haml templates for Asciidoctor that transform an AsciiDoc document into HTML5 slides animated by deck.js.
-
Ensure Asciidoctor, Haml and all their dependencies are installed:
$ gem install asciidoctor tilt thread_safe haml
-
Clone the asciidoctor-deck.js repository to get the templates necessary for converting AsciiDoc source to HTML slides:
$ git clone https://github.com/asciidoctor/asciidoctor-deck.js
-
Edit
CONTENT_FILE( *.adoc or *.ad or …):-
Slides & content per slide
-
(Optional) Set presentation options at top of
CONTENT_FILE. The options available & their values will depend on presentation library (some examples below).:${Attribute}: ${Value}
-
-
Generate HTML from the Asciidoctor templates
-
Command Line:
$ asciidoctor -T templates/haml CONTENT_FILE
-
Build Script: use Ruby, JavaScript, Gradle or your favorite build tool/script with presentation options
-
-
Copy or clone presentation library (to output destination/branch)
$ git clone https://github.com/imakewebthings/deck.js

Tip
|
If you are using GitHub Pages, plan ahead by keeping your source files on master branch and all output files on the gh-pages branch.
|
-
If you are planning to split your slides you also need to copy to
extensionsdirectory thedeck.split.jsfile which can be downloaded from GitHub -
If you want to use the fullscreen photo feature, you must create an
imagesdirectory.
Let’s see some examples of deckjs backend features:
= Title Slide Presenter Name == Slide One Foo Bar World [canvas-image=./images/cosplay.jpg] == Slide Two [.canvas-caption, position=center-up] Hello World - Good Bye Cruel World
In the previous snippet, we are creating a slide titled “Slide One” with bullets and another one titled “Slide Two” with centered text (the default behavior of deck.js) with speaker notes.
Some things to consider:
-
The
canvas-imageattribute receives as a parameter the location of image we want to use and always must go before the section. -
If you are planning to add a message over the image, you can do it as usually, but probably won’t be read good, using
positionattribute which positions text into the slide (bottom-left, top-left, bottom-right, top-right, center-up, center-down) andcanvas-captionrole will improve so much how text is rendered.
== Another Slide [%step] That's all. [%step] My Folks
In previous example we are creating one slide which instead of showing both paragraphs at the same time, will be presented each time you try to go to next slide.
And the same can be applied to lists, images, quotes, code:
== Yet Another Slide [%step] * A * B * C
In this case, each bullet will appear to screen each time you try to go to next slide.
