Growl Notification Transport Protocol for Python

Project description

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

# Send one message
    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
    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 growl 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,


GitHub issue tracker
