FSM

Summary

FSM is a finite state machine for Go.

It is heavily based on two FSM implementations:

Javascript Finite State Machine https://github.com/jakesgordon/javascript-state-machine

Fysom for Python https://github.com/oxplot/fysom (forked at https://github.com/mriehl/fysom)

For API docs and examples see http://godoc.org/github.com/looplab/fsm

Example

fsm := NewFSM(
    "closed",
    Events{
        {Name: "open", Src: []string{"closed"}, Dst: "open"},
        {Name: "close", Src: []string{"open"}, Dst: "closed"},
    },
    Callbacks{},
)

fmt.Println(fsm.Current())

err := fsm.Event("open")
if err != nil {
    fmt.Println(err)
}

fmt.Println(fsm.Current())

err = fsm.Event("close")
if err != nil {
    fmt.Println(err)
}

fmt.Println(fsm.Current())
