If you want a simple string list with word and value together, there is a function to convert.

open Inquirer_oc

(* string list *)
let flower_list = [ "sunflower"; "tulip"; "rose"; "daisy"; "lily" ]

let question_option : Question_list_type.question =
  {
    name = "flower";
    prompt_type = List;
    message = "What's your favorite flower?";
    (* convert choices string x -> {word: x; value: x} *)
    choices = Question_list.string_list_to_choice_list flower_list;
    page_size = Some 5;
  }

let result = Question_list.list_question question_option
let () = print_endline result

input

open Inquirer_oc

let question_option : Question_input_type.question_input_option =
  {
    name = "flower";
    prompt_type = Input;
    message = "What's your favorite flower?";
    default = Some "rose";
  }

let result = Question_input.question_input question_option
