Bridgetown reveal.js Plugin

Bridgetown is a ruby powered static site generation. Reveal.js is an open source HTML presentation framework.

This plugin wires the two together so that you can use bridgetown to host a reveal.js presentation as a section of your site.

Installation

Using an Automation

The preferred method to install this plugin is to run the automation. There are files to add / update to your site that uses this plugin and it is most easily done through the automation.

bin/bridgetown apply https://github.com/copiousfreetime/bridgetown_reveal

Manual Installation

Run this command to add this plugin to your site's Gemfile.

bundle add bridgetown_reveal

And then run the automation locally:

./bin/bridgetown apply $(bundle show bridgetown_reveal)/bridgetown.automation.rb

If you prefer NOT to run the automation, then look at the the automation file and apply the updates manually:

https://github.com/copiousfreetime/bridgetown_reveal/blob/main/bridgetown.automation.rb

The steps are:

1. Add the initializer to your configuraiton in config/initializers.rb

   init :bridgetown_reveal

2. Add reveal.js to your yarn package: yarn add reveal.js
3. Install the javascript for bootstrapping reveal.js and import it
4. Update the bridgetown.config.yml to add the slides collection.
5. Install a sample presentation

Usage

The plugin will add a new layout type of bridgetown_reveal/deck and an associated component of ::BridgetownReveal::Deck.

Integrating a reveal.js presentation into your site involves 3 items:

• Setting a collection for the slides in the top level bridgetown.config.yml.
• Create the single presentation page.
• Creating all the slide content.

For example, if to make a new presentation at output location /slidey you would do the following:

Add the slidey collection to the bridgetown.config.yml file:

collections:
    slidey:
      sort_by: order
      name: Slidey

Create the page for the presentation at src/slidey.erb

---
layout: bridgetown_reveal/deck
---

<%= render ::BridgetownReveal::Deck.new(site: site, collection: 'slidey') %>

Put all the slidey content pages themselves in src/_slidey/. The pages will all be combinded together and sorted based upon the order value in the frontmatter.

src/_slidey/intro.html

---
order: 1
---
<section>
  <h1>The first slide of the Intro</h1>
</section>

<section>
  <h1>The 2nd slide of the Intro</h1>
</section>

src/_slidey/outro.html

---
order: 100
---
<section>
  <h1>The penultimate slide of the talk.</h1>
</section>

<section>
  <h1>Thank you, and goodnight</h1>
</section>

All of the content is reveal.js <section> content. The top level wrapper for reveal.js is inside the bridgetown_reveal/deck layout.
