In this implementation the description of a state machine could be written in yml., _(*5)

An example state machine could be like:, _(*6)

Name: door

Start: "dc"

Event:
- ["close door", "CD"]
- ["open door", "OD"]
- ["open window", "OW"]
- ["close window", "CW"]


State:
- "dc"
- "do"
- "wo"
- "wc"

Transition:
- ["dc", "OD", "do"]
- ["do", "OW", "wo"]
- ["wo", "CW", "wc"]
- ["do", "CD", "dc"]

In '''Event''' block all events are listed in the format [name, code]. Code must be unique. This code is also used to drive the machine., _(*7)

In '''State''' block all states are listed in the format "name"., _(*8)

In '''Transition''' block all transitions are listed in the format [startState, event, targetState]., _(*9)

The sample use of state machine and controller could be see in the test directory., _(*10)

Install per Composer

{

    "require": {
        "tiddr/state_machine": "dev-master"
    }
}

Then just add, _(*11)
