   @spec terminal? :: boolean
   @spec terminal?(:io.device) :: boolean

  The format for referring to sequences is `%{red}` and `%{red,bright}` (for
  multiple sequences).

  It will also append a %{reset} to the string. If you don't want this
  behaviour, use `escape_fragment/1` and `escape_fragment/2`.

  An optional boolean parameter can be passed to enable or disable
  emitting actual ANSI codes. When false, no ANSI codes will emitted.
  By default, standard output will be checked if it is a terminal capable
  of handling these sequences (using `terminal?/0` function)

  ## Example

      iex> IO.ANSI.escape("Hello %{red,bright,green}yes", true)
      "Hello \e[31m\e[1m\e[32myes\e[0m"
