Support []int for writing indexes in addition to []string about survey HOT 4 CLOSED

@ahmetb i'm going to close this now since the settable interface is now merged. Also, #92 should handle the int -> string conversions in the deeply nested cases (as in the MultiSelect example you shared above)

from survey.

Hey @ahmetb thanks for the detailed use case, I'm personally not a fan of returning an index from the list of options in a multi select prompt because i think it would create 2 different ways of retrieving data from a multi select which I think unnecessarily overcomplicates the API. Instead would like to add support for []int in the case where the options are []string{"1", "2", "3"} and the answers would then be converted to the right types.

I recognize this doesn't solve your issue so let I suggest implementing the interface described here and put the transformation from a list of strings to products in the interface method.

Another feature that could be added to support your usecase is having an object that allows for a different displayed question from the one that is returned by the prompt. This could look like

survey.MultiSelect{
    Message: "which products do you want?",
    Options: {}survey.Option{
        {Display: "ProductName1", Value: 123},
        {Display: "ProductName2", Value: 514},
    }
}

from survey.

Your suggestion sounds interesting, how about instead of a well defined struct, accepting something like []fmt.Stringer (or []survey.Option , which would be an interface that requires func DisplayName() string?

In your example, I would probably use Value to store indexes.
