문자열 거꾸로 하기 with Common Lips

▒ Common Lips 소스:  testStringReverse.lsp

#!/usr/bin/env clisp

(defun my-string-reverse (s)
    (let* ((arr (concatenate 'list s))
           (arr2 (reverse arr)))
        (format nil "~{~A~^~}" arr2)
    )
)

(setf s "Hello, world!")
(setf s2 "안녕하세요?")

(format t "s = ~A~%" s)
(format t "(reverse s) = ~A~%" (reverse s))
(format t "(my-string-reverse s) = ~A~%" (my-string-reverse s))
(format t "s2 = ~A~%" s2)
(format t "(reverse s2) = ~A~%" (reverse s2))
(format t "(my-string-reverse s2) = ~A~%" (my-string-reverse s2))

;; --------------------------------------------------------------
;; 출력 결과(CLisp 에서  MS949 인코딩으로 소스를 저장한 경우):
;;    s = Hello, world!
;;    (reverse s) = !dlrow ,olleH
;;    (my-string-reverse s) = !dlrow ,olleH
;;    s2 = 안녕하세요?
;;    (reverse s2) = ?요세하녕안
;;    (my-string-reverse s2) = ?요세하녕안

위의 예제에서 보듯이 CP949 한글의 문자열을 거꾸로 하기가 CLisp의 경우에는 잘 동작함이 확인되었다.
이를 대화형 모드(inttractive mode) CLisp에서 다시 한번 확인해 보자.
