# fsme
Finite State Machine Engine for Go
[](https://godoc.org/github.com/batazor/fsme/fsm)
### Try it
1. [Demo](https://fsme.herokuapp.com/)
-----
-----
### Install
`go get github.com/batazor/fsme/fsm`
### Basic Example
From [examples/simple.go](./examples/simple.go)
```go
package main
import (
"fmt"
"github.com/batazor/fsme/fsm"
)
func main() {
// Create new FSM
machine, err := fsm.New()
// Add rule
machine.AddStateTransitionRules("a", "b", "c")
machine.AddStateTransitionRules("b", "d", "e")
machine.AddStateTransitionRules("c", "k")
machine.AddStateTransitionRules("d", "a")
machine.AddStateTransitionRules("e", "k")
machine.AddStateTransitionRules("k")
// Add Events
machine.AddEvent("start", "a")
machine.AddEvent("to b", "b")
machine.AddEvent("to d", "d")
// Add callback for state
machine.AddCallback("a", "enter", func(f *fsm.FSM) { fmt.Println("Enter state: ", f.GetCurrentState()) })
machine.AddCallback("a", "leave", func(f *fsm.FSM) { fmt.Println("Leave state: ", f.GetCurrentState()) })
machine.AddCallback("b", "enter", func(f *fsm.FSM) { fmt.Println("Enter state: ", f.GetCurrentState()) })
// Init State
err = machine.SetStateTransition("a")
if err != nil {
fmt.Println(err)
}
// Send Event
err = machine.SendEvent("to b")
if err != nil {
fmt.Println(err)
}
err = machine.SendEvent("to d")
if err != nil {
fmt.Println(err)
}
fmt.Printf("State: %s\n", machine.GetCurrentState())
}
```
