Ruby bindings for the Wt web development toolkit, which  
allow you to write widget based web applications wired up  
with ‘signals’ and ‘slots’ in a very similar manner to a  
desktop toolkit such as Qt. The Wt::Ruby bindings runtime is  
derived from the well proven QtRuby code, and so it could be  
described as a ‘QtRuby for web programming’.

Hello World with quit button:

#!/usr/bin/env ruby  
require ‘wt’

class HelloApplication \< Wt::WApplication  
def initialize(env)  
super(env)  
root.addWidget(Wt::WText.new(“

# Hello, World!
”))  
button = Wt::WPushButton.new(“Quit”, root)  
button.clicked.connect(SLOT(self, :quit))  
end  
end

Wt::WRun(ARGV) do |env|  
HelloApplication.new(env)  
end

Note that this forms a complete web server that can be run  
from the command line as follows:

$ ./hello.rb --docroot . --http-address localhost  
–http-port 3000

To deploy the same code via FCGI running under a web server  
such as Apache, you just need to change the environment  
variable WT\_ENV from ‘development’ (or unset) to  
‘production’.

Requirements

- Ruby 1.8.x or 1.9.1
- Wt 2.2.3 or Wt 2.99.0 or greater
- cmake 2.6.x
- boost 1.35 or greater

Installed wtruby without trouble, but got the following error when  
running  
the Hello World script you included in the annoucement
