All the files you will work with in creating your presentation use the basename "deck." Defaults are set for you when generating a new project with penguin new. For the HTML, CSS, and JS files, the file extensions should match whichever preprocessors you're using for the given type. The generator uses Haml, Sass, and CoffeeScript by default, but you can use any libraries you like.

  • deck.rb is the configuration file. Require any HTML template engine and CSS/JS preprocessors you want here. Call set :template_engine, :engine_name_here to tell Penguin which library to use for generating your HTML.

  • deck.haml is your presentation HTML.

  • deck.sass is your presentation stylesheet.

  • is your presentation JavaScript.

Presentation format
