General purpose notification mechanism for Lua

[Tiago Katcipis <katcipis@...>]

First of all, this is my first post on this list, forgive me if the question is not brilliant :-).

I am starting to develop a application on Lua and since there is the need to do a lot of communication between objects, to loose coupling i was thinking on using some kind of generic purpose notification system like GSignal (http://library.gnome.org/devel/gobject/unstable/gobject-Signals.html), or like the event system used on QT, using something like this raises the flexibility of the system. Building a notification system in Lua is not very hard, but it is useless to build a new one if maybe there is something already done. I have done some research, include on luarocks, but i didn't found anything, everything that i found about events was related to poll, select, kqueue (Multi tasking stuff, like luaevent and luasys). But this is not what i really want, i want something to make easier a 1 to many relationship, not to make poll on file descriptors, sockets, etc.

If someone can help me, i would appreciate.

Best regards,
