Signals from outer space
This library is a competing Signaling implementation, modeled after Bodil's purescript-signal library.
It's differences?
- The signal effects for all handlers are explicit in Zeta
- Zeta Signals are traversable, but not functors, because mapping over a signal creates a new one (signals are references)
- There's an included
StrMap-based signaling system, but it's not that useful
Generally, I just wanted a pure implementation of Bodil's Signal library - this one is probably much slower, and will break api compliance, so fair warning!
Philosophically, this library competes with purescript-queue in the following ways:
- Queues pass messages to handlers, while Signals maintain a single state acknowledged by handlers
- Both Queues and Signals can have multiple handlers
- Signal handlers are informed of a state change, while Queues are informed of message subissions
- Signals can be manipulated by time or rate debouncing easily - signals are meant to be composed into new onces, while Queues aren't merged or composed
