Send Growl notifications from your ColdFusion App

Ok, so i realised there are many coldFusion developers on macs now and if you are like us then you love getting notifications of everything via Growl!

So we thought how cool would it be to be able to send growl notifications from any CF app, like sending the mac-using CEO a growl notification each hour with a sales summary, etc...

We also noticed there were a few implementations already (in ruby, php, python, java) but none in our favourite language (and the java implementation was bloated with a growl listener client included... where as we want a fast coldFusion native easily modifiable sending solution only + you don't need to do no funky installations)

Ok, so after a long night, using the other examples as reference, i've got a working alpha prototype that allows you to setup as easily as:

application.objGrowl = createObject('component','growl').init(appName='cfGrowl:My App');

then add some available notification types:

application.objGrowl.addNotification(notification='Company Sales',enabled=true);
application.objGrowl.addNotification(notification='Site Error',enabled=true);

then add client hosts to receive the notifications:

application.objGrowl.addHost(host='192.168.0.1',password='1s2v3');
application.objGrowl.addHost(host='192.168.0.2',password='1@23$45');

then broadcast a new notification:

application.objGrowl.sendNotification(
   notificationType='Company Sales',
   title='Website Store Hourly Sales Report',
   message='5 orders, 10 products, $3000 revenue',
   priority = 0,
   sticky = false);

so the code is attached, and we've only tried it currently with static IPs in an intranet environment, so it may need tweaking to work with firewalls, not entirely sure about that, or you could target with port forwarding a single mac machine that using growl network options can relay broadcast to all local machines... something to look at in future anyway.

you need to make sure you've got "listen for incoming notifications" and "allow remote application registration" checked in the network options tab in system preferences, and enter a server password, that you then enter when you add your IP and password as a new host.

also i read that snarl client for PC plans on being able to consume growl notifications in near future so this could soon be an even cooler cross platform solution

i'll make a riaforge project out of this if people show interest to further develop features (like writing hosts out to an XML file so they aren't lost on application restart), otherwise just our office will have the coolest coldfusion app notifications in the world ;)

That is cool as hell. Seriously. Now I wish I had a network of macs that I could play with. This would be great in a mac-centric office.

Yeah well, we are hoping to pull more people in our office over to the darkside...only about 20% mac :) but yeah i now envisage this as part of a bigger global notifications system where mac users get awesome unobtrusive growl notifications and the windows users will get their notifications via Jabber IM, as we've just rolled out our own server in the office for CF to talk through... fun times ahead!

Hi David,
Very cool - nice implementation of it. Now I have to see if there is something similar for Linux :-)
Cheers,
Mark

here's a clone someone made for linux, not sure if it is network enabled http://www.mumbles-project.org/screenshots, i don't think it would consume growl packets either, but if we picked a client to support for each platform we could then make a plug-in style x-platform notification service, where you could plugin support for new clients

# Posted By David Sirr | 5/8/07 1:50 PM

This is definitely worth a RIAForge project. I also like the idea of writing out the notification settings to an XML file....or some other persistence mechanism. Good job--I think this is really cool!

ok riaforge project now online @ http://cfgrowl.riaforge.com

Very cool indeed! Wrapping one's head around the UDP networking required for this is a serious chore, thanks for taking it on!

# Posted By Mark | 6/19/07 7:15 AM

cheers, the hardest part was getting my brain to process the bitwise stuff to build the packets properly

I noticed the mention of my mumbles project and thought I'd drop a comment and let everyone know that the newest version, mumbles 0.4, has growl network notification support. Using this application, you could now send the same notifications to a linux box running mumbles.

If you try it out, please let me know how it went.

Thanks,

I tested this camera for a client. I didn’t have the light running for more than 15 minutes. The battery lasted approximately 6 hours before recharging. The LCD, however, had a few dead pixels - never saw this before. Tried returning for exchange and had to put up quite a fight. Anyone else seen this? http://www.e-lw.com
