Parade is an open source presentation software that consists of a Sinatra web app that serves up markdown files in a presentation format. Parade can serve a directory or be configured to run with a simple configuration file.
Parade is easily out-done by professional presentation software packages as far as out-of-the-box style and design. However, there are benefits that Parade has over presentational software:
-
Markdown backed data
This ultimately makes it easier to manage diffs when making changes, using the content in other documents, and quickly re-using portions of a presentation.
-
Syntax Highlighting
Using GitHub flavored markdown, code fences will automatically be syntax highlighted, making it incredibly easy to integrate code samples.
-
Code Execution
Slides are able to provide execution and show results for JavaScript and Coffeescript live within the browser. This allows for live demonstrations of code.
-
Web
Slide presentations are basically websites -- they run in your browser from your desktop. This allows for a wide range of possibilities for customization and expandability.
-
Basic Templating and Color Schemes
Several templates and color scheme options have been provided to help you get started. While Parade does not currently provide anything near the variety of many other presentation packages, it is well-suited for basic presentations.
-
Design Flexibility (pros and cons)
Unless you're skilled in CSS/Animations, you will likely have a harder time creating presentations with as much polish as other programs provide. However, this approach also makes Parade incredibly flexible if you do understand CSS/Animations.
-
Resizing
Currently, the presentation system can change gradual sizes, but does not have true full screen mode.
$ gem install parade
$ parade
By default, running parade starts a presentation from the current working
directory. It finds all markdown files, **/*.md
, within the directory
and creates a presentation out of them.
By default parade will split slides along lines that start with a single
#
You can manage the presentation with the following keys:
Advance to the next slide or advance the next incremental bullet point or show the end result of the code execution.
Move to the previous slide
Toggle help
Toggle footer (which shows slide count of total slides, percentage)
Toggle the display of the Table of Contents
Visit "http://localhost:9090/print"
Visiting this URL will generate a single page presentation that is printable
$ parade [directory]
This will start a presentation from the specified directory, finding all markdown files contained within the directories or sub-directories.
To include certain files, specify an order, or duplicate slides, you will need to
define a parade
file. Within that file, you may define specific files,
specific folders, and the order of the presentation.
title "My Presentation"
slides "intro.md"
section "directory_name"
slides and section are exactly the same. However, you may choose to use one over the other depending on if you are mentioning a specific file of slides or a directory which could contain another
parade
or be considered a section.
You can also define sub-sections with a title and slides or additional sections.
title "My Presentation"
section "Introduction" do
slides "intro.md"
end
section "Code Samples" do
slides "ruby"
slides "javascript"
section "coffeescript"
end
Slides are simply markdown format. Slides will be separated along
the #
elements within your document.
Relying on the #
as a separator is not always ideal. Alternatively, you can
use the !SLIDE
separator. This also provides you with the ability to define
additional metadata with your slides and presentation.
!SLIDE
# My Presentation
!SLIDE bullets incremental transition=fade
# Bullet Points
* first point
* second point
* third point
Using this separator will immediately override
#
, so you will have to insert!SLIDE
separators in all places you would like cut your slides.
You can define special notes that are shown in presenter mode.
Presenter mode has been removed until it can be rebuilt
Add a line that starts with .notes:
## Important Slide
* First Thing
* Second Things
.notes The reason that the second thing came about is because things changed.
In this example, the HTML output will contain a
<p class='notes'>
Toggle presenter notes with then
key while in the presentation.
Presenter mode has been removed until it can be rebuilt
!SLIDE #slide-id-1
In this example the id of the slide div would be set to
#slide-id-1
You can define an ID that will be added to the slide's div
. This id will be
set to any value prefaced with the #
character.
!SLIDE transition=fade
In this example, the slide will fade when it is viewed. This will set
data-transition='fade'
on the slides'sdiv
.
You can define transitions from the available body of transitions.
The transitions are provided by jQuery Cycle plugin. See http://www.malsup.com/jquery/cycle/browser.html to view the effects and http://www.malsup.com/jquery/cycle/adv2.html for how to add custom effects.
- none (this is the default)
- blindX, blindY, blindZ
- cover
- curtainX, curtainY
- fade
- fadeZoom
- growX, growY
- scrollUp, scrollDown, scrollLeft, scrollRight
- scrollHorz, scrollVert
- shuffle
- slideX, slideY
- toss
- turnUp, turnDown, turnLeft, turnRight
- uncover
- wipe
- zoom
!SLIDE bullets incremental my-custom-css-class
In this example, this will add custom css classes to the slide's
div
will display the following classes:class='content bullets incremental my-custom-css-class'
. Note: the content class is added by the default slide template.
All remaining single terms are added as css classes to the slide's div
.
Parade defines a number of special CSS classes:
places the content closer to the center of the page
centers images on a slide
places the title at the top and the content is left-aligned below it.

make all slide text size from 70% up to 150%, by percent increments of ten. E.G.: text-size-150, text-size-120, text-size-90, text-size-70.
on Javascript and Coffeescript highlighted code slides, you can click on the code to execute it and display the results on the slide
a slide without content is removed unless you specify that the slide is blank.
Parade comes with a set of themes which can be enabled in your parade file:
title "My Presentation"
theme "hack"
section "Introduction" do
slides "intro.md"
end
- archetect
- hack
- hayfield
- merlot
- minimal
- slate
The presentation has the following default footer:
<div id="footer">
<span id="slideInfo"></span>
<span id="debugInfo"></span>
<span id="notesInfo"></span>
</div>
You can override the default footer of the presentation by specifying a file path to a customized footer.
title "My Presentation"
footer "custom_footer.erb"
section "Introduction" do
slides "intro.md"
end
This example will load a file named customer_footer.erb
within your presentation directory.
By default Parade will load most CSS and JavaScript it finds within the the directory which parade was launched, the current working directory.
You may however also specify a single resource folder or multiple resource folders which parade will load instead of the current working directory.
title "My Presentation"
theme "hack"
resources "scripts"
resources "stylesheets"
section "Introduction" do
slides "intro.md"
end
The following will look for a folder named scripts and a folder named stylesheets relative to the current working directory and load all the CSS and JavaScript files found within those directories.
To insert custom JavaScript into your presentation you can either place it into a file (with extension .js) into the root directory of your presentation or you can embed a script element directly into your slides. This JavaScript will be executed—as usually—as soon as it is loaded.
If you want to trigger some JavaScript as soon as a certain page is shown or when you switch to the next or previous slide, you can bind a callback to a custom event:
- parade:willAppear
triggered before the slide is presented
- parade:didAppear
triggered after the slide is presented
- parade:show
triggered after the slide is presented
- parade:willDisappear
triggered before the slide disappears
- parade:didDisappear
triggered after the slide disppeared
- parade:next
triggered when an attempt to move to the next slide or incremental bullet point
- parade:prev
triggered when an attempt to move back a slide or incremental bullet point
These events are triggered on the "div.content" child of the slide, so you must add a custom and unique class to your SLIDE to identify it:
!SLIDE custom_and_unique_class
# 1st Example h1
<script>
// bind to custom event
$(".custom_and_unique_class").live("parade:show", function (event) {
// animate the h1
var h1 = $(event.target).find("h1");
h1.delay(500)
.slideUp(300, function () { $(this).css({textDecoration: "line-through"}); })
.slideDown(300);
return false;
});
</script>
This will bind an event handler for parade:show to your slide. The h1-element will be animated, as soon as this event is triggered on that slide.
If you bind an event handler to the custom events parade:next or parade:prev, you can prevent the default action (that is switching to the appropriate slide) by returning false:
!SLIDE prevent_default
# 2nd Example h1
<script>
$(".prevent_default").live("parade:next", function (event) {
var h1 = $(event.target).find("h1");
if (h1.css("text-decoration") === "none") {
h1.css({textDecoration: "line-through"})
return false;
}
});
</script>
This will bind an event handler for parade:next to your slide. When you press the right arrow key the first time, the h1-element will be decorated. When you press the right arrow key another time, you will switch to the next slide.
The same applies to the parade:prev event, of course.
To insert custom Stylesheets into your presentation you can either place it into a file (with extension .css) into the root directory of your presentation or you can embed a link element directly into your slides. This stylesheet will be applied as soon as it is loaded.
The content generated by the slide is wrapped with a div with the class .+content+ like this.
<div class="content">
<h1>jQuery & Sinatra</h1>
<h2>A Classy Combination</h2>
</div>
This makes the .content tag a perfect place to add additional styling if that is your preference. An example of adding some styling is here.
.content {
color: black;
font-family: helvetica, arial;
}
h1, h2 {
color: rgb(79, 180, 226);
font-family: Georgia;
}
.content::after {
position: absolute;
right: 120px;
bottom: 120px;
content: url(jay_small.png);
}
Note that the example above uses CSS3 styling with ::after and the content -attribute to add an image to the slides.
