回复 18# alexsum 的帖子
也是一个办法.不过,sd-read-from-string应该是read-from-string的改良版., u0 ]# h, X* n, S
3 A$ r6 x# e4 ~! P* R( Z( Z: d8 S(sd-read-from-string string)0 \& n _6 c5 S
Description: Same as the standard Lisp function read-from-string except that this function can handle empty strings or strings with just space characters.
( g E8 a% I; v, } \
' I) U+ O! y" u& Y# x' O1 A. r1 S遇到空键时,是有分别的.
! S+ Y+ @- T$ p/ {/ Y! z# w" Y(display (read-from-string " "))9 a: t7 E4 P# E4 H
(display (oli::sd-read-from-string " "))
$ F0 Y6 }0 V8 A6 W: H6 y7 Z) L; N5 f
