A library to easily create rich and interactive prompts in the terminal.

Inpired by [`AlecAivazis/survey`](https://github.com/AlecAivazis/survey)

Use `survey.Question` for `String` input and `survey.Confirmation` for `Bool` input.

```sh

gleam add survey

```

```gleam

import survey

import gleam/option.{type Option, None, Some}

pub fn main() {

  let assert [

    #("first_name", survey.StringAnswer(first_name)),

    #("last_name", survey.StringAnswer(last_name)),

    #("survey_fan", survey.BoolAnswer(survey_fan)),

  ] =

    [

      #(

        "first_name",

        survey.new_question(

          prompt: "First Name:",

          help: Some("Please enter your first name"),

          default: None,

          validate: None,

          transform: None,

        ),

      ),

      #(

        "last_name",

        survey.new_question(

          prompt: "Last Name:",

          help: Some("Please enter your last name"),

          default: None,

          validate: None,

          transform: None,

        ),

      ),

      #(

        "survey_fan",

        survey.new_confirmation(

          prompt: "Are you a survey fan?:",

          help: Some("It's a great library"),

          default: Some(True),

          transform: Some(fn(_: Bool) -> Bool { True }),

        ),

      ),

    ]

    |> survey.ask_many(help: False)

  case survey_fan {

    True -> io.println("Hello, " <> first_name <> " " <> last_name <> "!")

    False -> io.println("I don't believe you")

  }

}
