Parade is a slide presentation deck built with developers in mind.

You compose parade presentations in markdown files and these files are presented as a small web-application. This allows you to quickly build technical presentations within minutes within your text editor instead of the tedious drag'n'drop and arrange you find in most presentation packages.

• 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:

space or cursor right or cursor down

Advance to the next slide or advance the next incremental bullet point or show the end result of the code execution.

shift-space or cursor left or cursor up

Move to the previous slide

` (backtick)

Launches a visor terminal within your presentation that allows you to go to a specific slide by number, name or partial match of the slide title: goto 12, goto start, goto end, goto javascript.

h or ?

Toggle help

f

Toggle footer (which shows slide count of total slides, percentage)

c or t

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.

!SLIDE

# My Presentation

!SLIDE

# 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 to your markdown which will not be displayed in the final presentation to the user.

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.

There are many ways you are able to customize your presentation.

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

Parade supports various slide formats. These can be specified alongside the slide separators. By adding a slide format, it adds a special CSS class to the slide that is rendered. You may also specify custom CSS classes and an Id.

!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.

Sometimes you want to add CSS classes to an entire section of slides:

section "Iteration 0" do
  css_classes "title-and-content"
  slides "iteration-zero-intro.md"
  slides "iteration-zero-example.md"
end

section "Iteration 1" do
  css_classes title"
  slides "iteration-one-intro.md"
  slides "iteration-one-example.md"
end

!SLIDE bullets incremental my-custom-css-class

In this example, this will add css classes to the slide's div and will display the following classes: class='content bullets incremental my-custom-css-class'.

Parade defines a number of common slide formats:

title

places the content closer to the center of the page

center

centers images on a slide

title-and-content

places the title at the top and the content is left-aligned below it.

section-header

similar to a title class except it is a litle further down the page.

bullets

sizes and separates bullets properly (fits up to 5, generally)

columns / comparison

creates columns for every ## markdown element in your slides (up to 4)

smbullets

sizes and separates more bullets (smaller, closer together)

command

monospaces h1 title slides

commandline

for pasted commandline sections (needs leading '$' for commands, then output on subsequent lines)

incremental

can be used with 'bullets' and 'commandline' styles, will incrementally update elements on arrow key rather than switch slides

text-size-(percentage)

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.

execute

on Javascript and Coffeescript highlighted code slides, you can click on the code to execute it and display the results on the slide

blank

a slide without content is removed from the presentation unless you specify that the slide is blank.

By default Parade will load most CSS 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 "stylesheets"

section "Introduction" do
  slides "intro.md"
end

The following will look for a folder named stylesheets relative to the current working directory and load all the CSS files found within the directory.

The presentation has the following default footer:

<div id="footer">
  <span id="slideInfo"></span>
  <span id="debugInfo"></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.

Sometimes adding a class is not strong enough for what you need. So that's why it is possible to override the entire slide template.

# Overrides the default slide template for the entire presentation
# This file is in the root directory of the presentation
template "default", "slide.erb"

section "Iteration" do
  # Overrides the default slide template for this SECTION of the presentation
  # This file is in the root directory of the presentation
  template "default", "iteration-slide.erb"
  slides "outline.md"
end

!SLIDE

Introduction

!SLIDE template=full_screen

section "Introduction" do
  # Overrides the all slides with the 'full_screen' template value set
  # This file is in the root directory of the presentation
  template "full_screen", "full_screen.erb"
  slides "outline.md"
end

What is a presentation without slide transitions. Parade supports a variety for slide transitions that can be specified alongside the side separator.

!SLIDE transition=fade

In this example, the slide will fade when it is viewed. This will set data-transition='fade' on the slides's div.

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

By default Parade will load most 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"

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 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 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 &amp; 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.
