# :: Javascript to Python ::
# the following function will be called when the template button is pressed
def show_message(msg):
    print(msg)
    printMessage(msg)

# configure the viper app with a name, a descripton and the template url
vp = viperapp.ViperApp("Viper IoT Notes Printer","Print your message!","resource://template.html")

# everytime Javascript generates the event "showmsg" the function show_message is called
vp.on("showmsg",show_message)

# run the ViperApp!
vp.run()
# since vp.run starts a new thread, you can do whatever else you want down here!
