(require 'cl-lib) (defun letter-to-index (l &optional offset) (let*((letters (list ?q ?w ?e ?r ?t ?y)) (pos (cl-position l letters)) (offs (or offset 10)) ) (when pos (+ offs pos) ))) ;; (letter-to-index ?a) ; nil ;; (letter-to-index ?q) ; 10 ;; (letter-to-index ?w) ; 11 ;; (letter-to-index ?e) ; 12 ;; (letter-to-index ?r) ; 13 ;; (letter-to-index ?t) ; 14 ;; (letter-to-index ?y) ; 15 ;; (letter-to-index ?u) ; nil HIH -- underground experts united https://dataswamp.org/~incal
