This Ruby extension provides graphical output under X.Org.


hornetseye-xorg requires the X.Org and Mesa development headers. If you are running Debian or (K)ubuntu, you can install them like this:

$ sudo aptitude install xserver-xorg-dev libxv-dev libxpm-dev libgl1-mesa-dev libglu1-mesa-dev libswscale-dev libboost-dev

To install this Ruby extension, use the following command:

$ sudo gem install hornetseye-xorg

Alternatively you can build and install the Ruby extension from source as follows:

$ rake
$ sudo rake install


Simply run Interactive Ruby:

$ irb

You can load and use the X.Org wrappers as shown below. This example shows how to display an image:

require 'rubygems'
require 'hornetseye_xorg'
include Hornetseye
img = lazy( 640, 480 ) { RGB 255, 0, 0 }

Here is another example. It demonstrates display of a video:

require 'rubygems'
require 'hornetseye_xorg'
include Hornetseye
X11Display.show do
  lazy( 320, 240 ) { RGB ( Time.new.to_f * 256 ) % 256, 0, 0 }
