multiple subscribers

[faassen]

Come up with a way so that multiple functions can be called when a dispatch function is called. This allows things like an event system.

Possible features:

• multiple generic functions that should all fire, instead of just one.
• specific subscribers using event system.
• topological sort so that subscribers can be made to fire after another (define order if two subscribers fire, but those subscribers may also fire independently)

Implementation notes:

• if predicate key is the same, add it to a list of functions to fire for that predicate key.
• use all functionality to make sure all subscribers fire.

Martijn,
How high is this issue on your priorities list?
Do you see it happening in the nearest future or we should not hold our breath?

(sorry, I got sick which delayed my response)

I don't think it's going to happen in the very near future as it's not needed for the application code I'm working on. I think for the moment you're better off using an external event system with Morepath.

I am going to try to find some time to work on it in, say, the next half year, though. (in the context of Reg)

Thank you for reply, Martijn. Get well soon!

Clearly I haven't managed to work on it yet. :)
