Class AcEdPromptStateMachine<TPromptOptions, TResult>

Example

type Prompt = { message: string }
type Result = { status: 'ok' | 'cancel'; value?: number }

class FirstState implements AcEdPromptState<Prompt, Result> {
  constructor(private sm: AcEdPromptStateMachine<Prompt, Result>) {}

  buildPrompt() {
    return { message: 'Enter first value:' }
  }

  handleResult(result: Result) {
    if (result.status !== 'ok') return 'finish'
    this.sm.setState(new SecondState(this.sm, result.value ?? 0))
    return 'continue'
  }
}

class SecondState implements AcEdPromptState<Prompt, Result> {
  constructor(
    private sm: AcEdPromptStateMachine<Prompt, Result>,
    private firstValue: number
  ) {}

  buildPrompt() {
    return { message: 'Enter second value:' }
  }

  handleResult(result: Result) {
    if (result.status !== 'ok') return 'finish'
    const sum = this.firstValue + (result.value ?? 0)
    console.log('sum', sum)
    return 'finish'
  }
}

const sm = new AcEdPromptStateMachine<Prompt, Result>()
sm.setState(new FirstState(sm))
await sm.run(async prompt => {
  // Editor interaction happens here:
  return { status: 'ok', value: 1 }
})
