GNTP Basics

Python bindings for the Growl Notification Transport Protocol

Bugs can be reported at the GitHub issue tracker

Simple Message Sending

from gntp.notifier import mini
# Send a simple growl message with mostly default values
mini("Here's a quick message", callback="http://github.com/")

gntp.notifier.mini(description, applicationName='PythonMini', noteType='Message', title='Mini Message', applicationIcon=None, hostname='localhost', password=None, port=23053, sticky=False, priority=None, callback=None, notificationIcon=None, identifier=None, notifierFactory=<class 'gntp.notifier.GrowlNotifier'>)

Single notification function

Simple notification function in one line. Has only one required parameter and attempts to use reasonable defaults for everything else :param string description: Notification message

Warning

For now, only URL callbacks are supported. In the future, the callback argument will also support a function

Detailed Message Sending

class gntp.notifier.GrowlNotifier(applicationName='Python GNTP', notifications=[], defaultNotifications=None, applicationIcon=None, hostname='localhost', password=None, port=23053)

Helper class to simplfy sending Growl messages

Parameters:

• applicationName (string) – Sending application name
• notification (list) – List of valid notifications
• defaultNotifications (list) – List of notifications that should be enabled by default
• applicationIcon (string) – Icon URL
• hostname (string) – Remote host
• port (integer) – Remote port

The GrowlNotifier class is intended to mostly mirror the older python bindings for growl

GrowlNotifier.register()

Send GNTP Registration

Warning

Before sending notifications to Growl, you need to have sent a registration message at least once

GrowlNotifier.notify(noteType, title, description, icon=None, sticky=False, priority=None, callback=None, identifier=None, custom={})

Send a GNTP notifications

Warning

Must have registered with growl beforehand or messages will be ignored

Parameters:

• noteType (string) – One of the notification names registered earlier
• title (string) – Notification title (usually displayed on the notification)
• description (string) – The main content of the notification
• icon (string) – Icon URL path
• sticky (boolean) – Sticky notification
• priority (integer) – Message priority level from -2 to 2
• callback (string) – URL callback
• custom (dict) – Custom attributes. Key names should be prefixed with X- according to the spec but this is not enforced by this class

Warning

For now, only URL callbacks are supported. In the future, the callback argument will also support a function

GrowlNotifier.subscribe(id, name, port)

Send a Subscribe request to a remote machine

Complete Example

import gntp.notifier

# Simple "fire and forget" notification
gntp.notifier.mini("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 = "computer.example.com", # 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 = "http://example.com/icon.png",
        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 = "http://example.com/icon.png",
        sticky = False,
        priority = -1,
)

# Send the image with the growl notification
image = open('/path/to/icon.png', 'rb').read()
growl.notify(
        noteType = "New Messages",
        title = "Now with icons",
        description = "This time we attach the image",
        icon = image,
)

GNTP Configfile Example

class gntp.config.GrowlNotifier(*args, **kwargs)

ConfigParser enhanced GrowlNotifier object

For right now, we are only interested in letting users overide certain values from ~/.gntp

[gntp]
hostname = ?
password = ?
port = ?
