Rails on the road

This is how to get the frontmost application (name) in OSX 10.5 Leopard via Applescript and using Ruby with rb-appscript gem… now the code!

Applescript:

tell application "System Events"
  set frontmostApplication to name of the first process whose frontmost is true
end tell

Ruby (rb-appscript gem):

    1 require 'appscript'
    2 include Appscript
    3 
    4 puts app('System Events').processes.select.map{ |p| p.name.get if p.frontmost.get }.compact.first
