xkcd and ruby

is Yesterday I noticed that yes ruby is really cool actually. One can very elegent and very easy to program with it. For the demonstration I've written a small program that displays the current xkcd comic in a window. It has only 20 lines of code!

 # / usr / bin / env ruby 
 require 'net / http' 
 require 'tk' 
 require 'tkextlib / tkimg' 
 
 str = Net:: HTTP.get (URI.parse ('http:/ / xkcd.com ')) 
 img_url = URI.parse (str.match (' http \\: \\ / \\ / imgs \\ \\ xkcd com \\ / comics \\ / \\ w + \\ png ') to_s) 
 File.... . open ('img.png', 'w') { = 
 
 TkLabel.new label = (root) 
 label.image = image 
 root.height Image.Height = '/ img.png.'; 
 root.width = image.Width; 
 label.place ('height' Image.Height =>, 'width' => image.Width) 
 Tk.mainloop
