Wingtips

A presentation tool written in ruby - write your slides in Ruby!

Ensure that JRuby is installed.

Add this line to your application's Gemfile:

gem 'wingtips'

Or to grab it straight from github

gem 'wingtips', github: 'PragTob/wingtips'

And then execute:

$ bundle

Or install it yourself as:

$ gem install wingtips

A wingtips presentation expects this layout:

presentation_folder/
  code/*.rb
  images/*.*
  slides/*.rb
  config.rb

And a basic slide looks like this:

class Bullets < Wingtips::Slide
  def content
    headline 'Use bullet points, would you?'

    bullet "It's easy isn't it?"
    bullet 'Just keep on'
    bullet 'with ease!'
  end
end

You can express the same slide an even more fluent DSL like this:

slide do
  headline 'Use bullet points, would you?'

  bullet "It's easy isn't it?"
  bullet 'Just keep on'
  bullet 'with ease!'
end

For more examples please refer to the samples directory!

You need need a special flag to start the presentation as it is needed by the JVM. You need to add JRUBY_OPTS=-J-XstartOnFirstThread when trying to launch a presentation. So to launch the sample you need to type:

JRUBY_OPTS=-J-XstartOnFirstThread bin/wingtips samples/wingtips_introduction

Otherwise without the JRUBYY_OPTS, you will encounter the following error on Mac OSX:
