A Clojure library designed to create deterministic finite state machines.
- Easy to use flat one level state machine.
- Define state machines that can accumulate values.
- Transitions with actions and guards.
- Graphically visualize the resulting state machines.
Refer to the documentation for more details.
Require the fsm-clj core name space.
(:require [fsm-clj.core :refer :all])
Define a simple traffic light state machine.
(defsm traffic-light [[:green -> :yellow when :to-yellow] [:yellow -> :red when :to-red] [:red -> :green when :to-green]])
(-> (traffic-light) (send-event :to-yellow) :state) ;; => :yellow
Graphically generate the State Machine (open a Swing viewer).
