Dependencies and supported browsers

Tested on Ruby 1.8.7 and 1.9.2. It works in the latests versions of Chrome, Safari and IE (9+). Firefox and Opera don't support the CSS zoom property, so slides will not resize correctly.


First install the dependencies (it may take some minutes):

gem install watchr
gem install thin

Then execute the following command:


If you don't have execute permission, try:

ruby watch


The demo slideshow in the "slideshow" folder contains instructions to get you started. Everything inside the "slideshow" folder is specific to a presentation. However, what's inside the "lib" folder and the "watch" script shouldn't be modified.


For more information and additional options execute:

./watch --help


slideshow.html was based on the HTML5 Slideshow project by Rob Flaherty. The code was extended and new features were added:

  • The ruby script which offers support for partials and automated build
  • Dimensions and proportional slide resizing according to a specified ratio (for example, 1280x800)
  • Additional options (for example, hide the toolbar but keep the slide number visible)
  • Live.js was added (browser automatic refresh)
  • Less.js was added
