Hi ! Very nice tool Stephen. It work on Ubuntu Dapper too. Very interesting for controlling/monitoring server-side pd too. I should update my AJAX/PHP tool too. http://pear.php.net/pepr/pepr-proposal-show.php?id=422 is not much used.

I might provide some beautiful XUL examples to help to spread it if I have time... A firefox extension is obivously a must. Is the pd patch extension for firefox abandonned ?

Hi,

...

is there a serialization for PD messages inside OSC? for example so one could load a webpage containing some XUL data hosted on padawan's site...it could check for a local PD instance, and shuttle the patch data over and open it..

If I understand you correctly, yes this is something I had in mind. Perhaps it could be used in a firefox extension instead of in a XULrunner app, so that you could browse to a server that hosts your audio interfaces. That would make setting up a networked audio system very nice and easy.

I'm not sure how it would work exactly in terms of the Mozilla security architecture, however, since as I understand it, remotely loaded pages can't access XPCOM components. I'm really not an expert with Mozilla, so if anyone has ideas on how to accomplish something like that I'd all ears.

Originally I wanted to do this is 100% javascript instead of having to create an XPCOM component, but it seems there is no way to have JS send UDP messages from a XUL app. As far I can tell anyways.

yup, thats the same i encountered, if you want to "easily" connect to XPCOM with mozilla/firefox, you have to do that code as an extension.

heres an "old" test that i made:

here i started to try to make a SVGUI library for XULRunner and PD:

Just to be clear: The Pd patch was to run on the server where also
the GUI stuff lives. And which is where the web-browser is pointed to.

Sorry for being a tad green. Andre Schmidt has made some SVG GUI examples http://osku.de/svg/gui-examples/. Say one would like to use such GUI's to - via OSC - control things in a Pd patch running on, say, localhost. What is the obvius next step?

My intuition doesn't ask for a Firefox extension, but rather some Java Script that can send the OSC messages to Pd. Any pointers would be nice.

Well, that's just the problem. There is no way to send UDP messages from JavaScript just like that. (As far as I know..)

So I wrote an XPCOM component which JavaScript can talk to as per my example. The XPCOM component is written in C++ and uses LibLo to send and receive OSC.

So say you wanted to get these SVG examples working with OSC. (Thanks for the link by the way!!)

The way my example works is that it is a XULrunner app (basically the firefox back-end), and it has a file called "oscapp.xul". This file tells it what the interface should look like. i.e., open a window and put a browser in it. In the <browser> tag there is an attribute which tells it to load the file "test.xhtml" into the browser. You could, for example, change this to point to your SVG files. Alternatively, have test.xhtml include your SVG files and arrange them on the page.

Then do the same thing I did in test.xhtml -- link to a JavaScript file, test.js, and create a function which instantiates the XPCOM component, called OpenSoundControl, and use it to send a message.

Take a look at "test.js" for an example of how to do it. I make no claims that my object has the best possible API, but it works.

The advantage of doing it this way over using a PHP or Python back-end is that it doesn't require running apache or communicating with it using HTTP, which probably introduces unwanted latency. The application just sends and receives OSC directly. (However, if you find writing a server back-end easier and more familiar, I say go for it!)
