Greetings, Recently, I was working on something that just wouldn't work properly. Rather than get frustrated, I decided to get a chuckle from the offensive fortunes through cookie(). I discovered to my dismay that the offensive fortunes are rot13 encoded. As a result, I wrote the following functions and figured I would submit them if they prove amusing/useful in any way. Have a nice evening, -Trey (defun rot13 (string) "Rot13 a string" (rot string 13)) (defun rot (my-str num) "Rotate a string by num characters, if num is greater than 26, bad things may happen" ;; result has one character concatenated to it for every iteration of mapcar (let ((result "")) (concat result ;; mapcar takes two arguments, a function and sequence, the sequence is ;; the list of characters which makes up the given string ;; the function in this case is the following anonymous lambda form. (mapcar (function (lambda (char) (cond ((and (< char 123) (> char 96)) ;; lowercase characters (if (> char (- 122 num)) (int-to-char (- char (- 26 num))) (int-to-char (+ char num)))) ((and (< char 91) (> char 64)) ;; uppercase characters (if (> char (- 90 num)) (int-to-char (- char (- 26 num))) (int-to-char (+ char num)))) (t char)))) (string-to-list my-str))))) -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Ashton Trey Belew Phone: 860 983 1046 e-mail: trey(a)veggie.wesleyan.edu http://veggie.wesleyan.edu/trey/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I shot a query into the net. I haven't got an answer yet, A posted message called me rotten But seven people gave me hell For ignoring mail I'd never gotten; And said I ought to learn to spell; An angry message asked me, Please Don't send such drivel overseas; A lawyer sent me private mail And swore he'd slap my ass in jail -- One netter thought it was a hoax: I'd mentioned Un*x in my gem "Hereafter, post to net dot jokes!"; And failed to add the T and M; Another called my grammar vile And criticized my writing style. Each day I scan each Subject line In hopes the topic will be mine; I shot a query into the net. I haven't got an answer yet... -- Ed Nather
