def prompt_non_empty(warning_message, &prompt_block)
  prompt_until_valid do
    value = prompt_block.call
    [value, value.strip.empty? ? warning_message : nil]
  end
end

#prompt_until_valid ⇒ Object

General loop-until-valid primitive. The block must yield [value, error_or_nil]. When error is a String, shows it as a transient warning. When error is a Callable (e.g. a lambda), uses it directly as the clear function. Loops until the block yields a nil error.
