Release 0.12.0

0.12.0 (2020-08-25)

This release adds two new features:

1. The onTransition-hook can be used to react to statechart state changes from the outside. This is useful when you want to persist statechanges or for instrumentation, logging etc. - onTransition behaves the same way as xstate's own interpreter#onTransition.

2. To align ember-statecharts with xstate/react, xstate/vue and xstate's own interpreter functionality ember-statecharts now allows starting the interpreter that useMachine creates in a specific state - overriding the usual initialState.

const machine = Machine({
  initial: 'inactive',
  states: {
    inactive: {
      on: {
        START: 'active',
      },
    },
    active: {
      on: {
        STOP: 'inactive',
      },
    },
  },
});

class Test extends Component {
  @use statechart = useMachine(machine, { state: this.args.state })
}

{{!-- assuming this.state === 'active' --}}
<Test @state={{this.state}} />

The above code will start the statechart in the active state.

The restart function in the update-hook will take this state into account as well:

{{!-- assuming this.state === 'active' on initial load --}}
<Test @state={{this.state}} />

{{!-- sets `state` to `inactive`--}}
<button type="button" {{on "click" this.setInactive}}>
  Deactivate
</button>

class Test extends Component {
  @use statechart = useMachine(machine, { state: this.args.state })
     .update(({ restart }) => {
        // will restart interpreter in this.args.state
        restart();
      })
}

In addition to starting/restarting automatically in the state passed in interpreterOptions ember-statecharts now also allows passing the state that the interpreter should be restarted in:

class Test extends Component {
  @use statechart = useMachine(wizardMachine)
     .withContext({
       step: this.args.step
     })
     .update(({ restart, context: { step } }) => {
        // will restart interpreter in the state passed as `args.step`
        restart(step);
      })
}

matchesState and debugState now also support statecharts that are named differently than statechart.

export default Component.extend({
  // ...

  isOn: matchesState('on', 'customStatechartName'),

  _debug: debugState('customStatechartName'),

  customStatechartName: statechart({
    initial: 'off',
    states: {
      off: {
        on: {
          POWER: 'on',
