      :param command: A string or a list of strings containing the name and
       arguments of the program.
      :param detach: If set to `True` the program will be executed using the
       `i3-msg` command. As a result the program is executed independent of
       i3pystatus as a child of i3 process. Because of how i3-msg parses its
       arguments the type of `command` is limited to string in this mode.
