UDP protocol info?

Hi,
would it be posssible to get a description of the Growl UDP datagram format (when not using DO) somewhere?

Growl seems exceptionally cool, and several REALbasic users are asking for Growl support. Since you can't use DO from REALbasic, I'd like to write a module using UDP...

Thanks for any pointers!

Cheers,
Frank+++

1) Growl has REALbasic bindings so you don't have to write it yourself.
2) Here are Growl's protocol specs - http://trac.growl.info/documentation/de ... otocol.php

If you don't like the bindings we have, might be easier to talk to applescript than udp. UDP is not guaranteed to be running, whereas applescript is always there.

Or you can talk to cocoa/carbon. You get more functionality that way, but it's not as easy afaik.

Yes, noticed that, but it didn't compile for me. Plus, it's based on AppleScript, and I prefer UDP.

Thanks, that's what I was looking for!

I'd really suggest not depending on udp.

Can I use the AppleScript interface to post notifications to remote machines on the network as well?

Could you clarify this? Do you mean to call into a framework/dylib with a "Declare" statement in RB?

You have to use udp for network notifications.. I was under the impression you were just going to use them for local notifications.

I'm not familiar with rb, but I do know that most languages can wrap most other languages.

Maybe if you told us what error message you were getting with the rb bindings, we could fix that.

There's no such thing as "inline C" or something in RB. But you can call libraries if you know the exact function names and arguments.

I get a "This method requires fewer parameters than were passed" on both the call to growlNotifyScript and growlRegisterScript. I don't know the reason; 6 parameters are passed to growlNotifyScript and 3 to growlRegisterScript, exactly what the scripts' "On Run" handlers require. But still I get this message.
