[MacRuby-devel] Ruby scripting of OSX Leopard - pointer needed

[Alan Skipp]

One way of achieving this is by using rb-appscript, which you can  
install as a rubygem:
http://appscript.sourceforge.net/rb-appscript/index.html

There's also the Scripting Bridge:

/apple_ref/doc/uid/TP40005424-SW1

The rb-appscript version of your Applescript would look like this:

require "rubygems"
require "appscript"
include Appscript

res = (`/usr/sbin/system_profiler SPDisplaysDataType | grep  
Resolution`).split
width,height = res.grep(/\d+/)

window = app("System  
Events").processes[its.frontmost.eq(true)].windows[1]
window.position.set([0, 22])
window.size.set([width, height])
