Validation in Form

[KernelDeimos]

Reply on #107 suggests validation works in Form prompts.

Visually, it does - the indicator changes based on whether the input is valid. However, the Form prompt doesn't re-try or throw an error on failed validation, forcing me to again validate and implement re-try manually. What I want is for the user to not be able to submit the form until it's valid.

Can you provide more details @KernelDeimos? It would be great if you could show a basic example of the form prompt you were trying to get working, with config, choices, etc.

@jonschlinkert here's mine:

  const prompt = new Form({
    name: 'user',
    message: 'Please provide the following information:',
    choices: [
      {
        name: 'firstname',
        message: 'First Name',
        validate(value){
          this.error = 'Invalid name'
          return false
        }
      },
    ]
  });

  prompt.run()
    .then(value => console.log('ANSWERS:', value))
    .catch(console.error)

I got:

although the validate always returns false, the user can press enter just fine 🤔 Am I missing something?
