A friend pointed out Music Playing Daemon to me; it’s the first thing I’ve found that makes it clear that it has similar goals to our jukebox software, ie a single playlist that’s under the control of multiple users.

Tobbe, thanks for the tip. I'm still getting to grips with the Erlang way of working - anyway, I've just found the guide to application directory structure, and I'll take your advice regarding priv. I'll post again when I've committed the changes to darcs.

Oh - there's a copy of the hmix source code in the util/ subdirectory.

Also: Where do I find this ‘hmix’ program that volume.erl wants to use ? (I’m running Gentoo btw and it doesn’t seem to exist among Gentoo’s packages)

Update: Found that I need to start Yaws in the same directory as the code. So now I don't get any errors in the log at least. Still doesn't work though.

It could be a good idea to structure the code under src,ebin,priv directories. The execdaemon binary then goes into the priv directory. You can then locate it with code:priv_dir/1. Example:

# erl -pa `pwd`/erlang_jukebox
1> l(spider).
{module,spider}
2>  code:priv_dir(erlang_jukebox).
"/home/www/site/erlang_jukebox/priv"

Another cool AJAX jukebox is at http://www.streampad.com

Seems a lot more advanced than this although certainly not as tiny!

@Tobbe: yes, just enqueueing it ought to do the trick. It’s very strange, the installation you have: it seems that some of the features are working, while others aren’t. For instance, typing in a chat message causes the history list to update, but the timer-based history (and playlist) refresh seems to be broken. Weird.

There’s really no comparison. This is a new, small, simple program, weighing in at 1,400 lines of Erlang and Javascript; Jinzora is a mature, large, complex program, with over 100,000 (!) lines of PHP code. Both are open-source, and both have something to do with playing MP3s in some kind of jukebox-like configuration, but that’s about where the similarities end, it seems to me.

Have you looked at jinzora? How is your Jukebox different than Jinzora? It has same functionality as yours and then some. Thanks.

Well, actually; I can’t get it to work :-)
Follow my link and see if it works for you.
It could be my server, I’ll have to check more closely.
Btw: how do I start playing a tune, just by enque it, or ?

Hey, great that you have it running!

The CSS problem is odd - how does it manifest itself? I'm using 1.5.0.7 here and it seems to work okay. Perhaps you have a developer plugin I've not tried?
