A simple way to ask one question at a time about survey HOT 4 CLOSED

I implemented this simply:

func askOne(p survey.Prompt) string {
	answers, err := survey.Ask([]*survey.Question{{Name: "q1", Prompt: p}})
	if err != nil {
		log.Fatal(err) // or whatever
	}
	return answers["q1"]
}

// Usage:
answer := askOne(&survey.Choice{
	Message: "...?",
	Choices: []string{"..."},
})

But it might be nice to see this available in the package itself.

I like this idea - if you had time to submit a PR I would gladly merge it in. I would do it myself but I think I will be pretty busy with the other issues.

Just curious, what sort of logic needs to happen? I'm wondering if there is something survey could be providing that would better support what you needed. The only usecase I could think of where one would need to change the question based on previous answers which I am still thinking on the right API for. If you have something different, I'd love to hear.

It's application-specific. In one case, I quit entirely ("are you sure you want to continue?" kind of thing). But yes, other times it is to add an extra follow-up question or to skip questions.

So I actually use your package more for getting input rather than doing an actual survey. I like how it formats the output and does multiple-choice, especially. Very pleasing to read and use. So I find myself asking one question at a time rather than batching them.

So I dunno how complicated you want your API to get, but if you felt like users need a more comprehensive solution you could consider something like a "computation graph" but with questions instead of computations. For each question, you'd need a function that maps possible answers to next questions.
