OSX 10.8 Mountain Lion - Migrate your stickies from Stickies.app to Notes.app

stickies-to-notes.rb

# Author: Ahmed Al Hafoudh <alhafoudh@freevision.sk
#
# Usage: ruby stickies-to-notes.rb
#
# Prerequisites:
#   gem install rb-appscript
#

require 'appscript'
require 'osax'

include Appscript

se = app('System Events')
stickies = app('Stickies')
notes = app('Notes')

se.application_processes['Stickies'].windows.get.each do |window|
  note = window.scroll_areas.first.text_areas.first.value.get
  notes.activate
  OSAX.osax.set_the_clipboard_to(note)
  se.keystroke('n', using: [:command_down])
  se.keystroke('v', using: [:command_down])
  sleep 0.5
end

Thks for this gist.
To make it work, I had to run Stickies and to check "activer l'accès pour les périphériques d'aide" in the system preferences.
