GNTP Python Library - #growl #gntp

Services available


Need anything else?

Contributors list


This is a Python library for working with the

Growl Notification
Transport Protocol 

It should work as a dropin replacement for the older Python bindings


You can install with pip


$ pip install gntp

then test the module


$ python -m gntp.notifier

Simple Usage


# GNTP uses the standard Python logging
import logging

import gntp.notifier

Simple "fire and forget" notification"Here's a quick message")

More complete example

growl = gntp.notifier.GrowlNotifier( applicationName = "My Application Name", notifications = ["New Updates","New Messages"], defaultNotifications = ["New Messages"], # hostname = "", # Defaults to localhost # password = "abc123" # Defaults to a blank password ) growl.register()

Send one message

growl.notify( noteType = "New Messages", title = "You have a new message", description = "A longer message description", icon = "", sticky = False, priority = 1, )

Try to send a different type of message

This one may fail since it is not in our list

of defaultNotifications

growl.notify( noteType = "New Updates", title = "There is a new update to download", description = "A longer message description", icon = "", sticky = False, priority = -1, )

URL based images do not work in the OSX version of

_ 1.4 You can send the image along with the notification to get around this.


image = open('/path/to/image.png', 'rb').read()
    noteType = "New Messages",
    title = "You have a new message",
    description = "This time we embed the image",
    icon = image,

.. note:: With Growl 2 and above user can choose to pass notification to system wide notifications center. In this case

argument would be ignored by the notification center (there would always be Growl icon instead).
