fsm2dot

Inspects a file containing a finite state machine defined using fsm-as-promised or javascript-state-machine libraries, and outputs the correspondent UML diagram using DOT graph representation.

Features

The following finite state machine:

/*
 * the file must contain
 * var StateMachine = require('fsm-as-promised');
 * or
 * var StateMachine = require('javascript-state-machine');
 */

var fsm = StateMachine.create({
  initial: 'start',
  final: 'stop',
  events: [
    { name: 'init', from: 'start', to: 'Ready' },
    { name: 'proceed', from: 'Ready', to: 'Steady' },
    { name: 'end', from: 'Steady', to: 'stop' },

    { name: 'test', from: 'Ready', to: 'Ready' }
  ],
  callbacks: {
    onReady: function () {},
    onleaveReady: function LeaveReady() {},
    onSteady: onS,
    ontest: function Activity() {}
  }
});

function onS() {}

will be converted to a DOT graph that can be visialized like this:

Command Line

Install node, then:

$ npm install -g fsm2dot

and run:

$ fsm2dot --help
