XML-RPC interface for Growl

Growl is a rather spiffy little notifier for OS X I’ve started using lately. Currently however, it’s lacking a nice way to send messages over the network. Since a project I’m working on would be even slicker with a way to communicate updates, I quickly tacked a Python XML-RPC Server onto Growl using Growl’s Python bindings.

In the future, Growl will have its own network interface, I’ve heard. Until then, this does the job quite nicely.

Please note: You will need to install the latest svn of Growl, the PyObjC bridge, and have Xcode 1.5 to get this working. Everything in ALL_CAPS should be changed as needed, this also assumes you want to use icons and they’re in a myIcons dir.


    import Growlimport SimpleXMLRPCServerfrom AppKit import NSImageimport sys, os.path

    iconPath = 'myIcons/'Icons = { 'MESSAGE_1' : 'MESSAGE_1.tiff', \
          'MESSAGE_2' : 'MESSAGE_2.tiff' }

    class MemberFunctions:
    def init(self,Icons):
        gn = Growl.GrowlNotifier()
        gn.applicationName = 'YOUR_APP_NAME'
        gn.applicationIcon = Icons['appIcon']
        gn.notifications = ['MESSAGE_1','MESSAGE_2']
        gn.register() = gn
        self.Icons = Icons

    def notify(self, ntype, title, description, sticky):
        gn =
        Icons = self.Icons
        nIcon = Icons['appIcon']
        if ntype  'MESSAGE_1':
            nIcon = Icons['MESSAGE_1']
        elif ntype  'MESSAGE_2':
            nIcon = Icons['MESSAGE_2']
            icon=nIcon, sticky=sticky)
        return 1

    def loadIcons(icons):
    global iconPath
    for icon in icons.keys():
        filename = icons[icon]
        nImagePath = os.path.abspath(iconPath+filename)
        nIcon = NSImage.alloc().initWithContentsOfFile_(nImagePath).autorelease()
        if not nIcon:
            sys.stderr.write(“Couldn't load file %s\n” % nImagePath)
        icons[icon] = nIcon
    return icons

    Icons = loadIcons(Icons)

    Make our XMLRPC Server, create our instance, and assign it
    server = SimpleXMLRPCServer.SimpleXMLRPCServer((“IP_TO_BIND_TO”, 7300))memfun = MemberFunctions(Icons)server.register_function(memfun.notify)

     Start the server
