A simple bulletin board for managing channels in an event bus system. This is extracted from closed source code I've been using for a while. It's not feature complete, because I did not need all the features. But as an open-source library I will make time to add all the HOFs in core.async.

I use this setup within integrant keys allowing for a visual way to see how channels are connected. Because of the way core.async manages it's mults, taps, pubs and subs, closing almost all the channels occurs by closing the event bus. I've never bothered to add a close function to this library because the wiring is meant to be immutable. All channels are added and wired at integrant init and not intended to be changed after that. Although if your needs differ. As a plus, mixing this with integrant.repl.state and portal makes it dead simple to reason about what is happening in your system.
