I tried the following: (require 'cl) (defstruct (ModeLine (:constructor nil) (:constructor new-ModeLine (type description display function)) ) (type :read-only t) (description :read-only t) (display :read-only t) (function :read-only t) ) (setq e (new-ModeLine "word" "Display number of words" "W" 'buffer-count-words ) ) This seems to do what I want. A few questions remain: - Is there a way to make sure that type, description and display are of type string and function of type function? - Is there a way to make sure that none of the elements are empty? - I would like to have a list (or other data structure) filled with only objects of type ModeLine. What is the best way to do this? - Is it possible to have all type and display values distinct?
