string-to-number 用来将字符串转化为数字,它可以支持从2到16进制的转化,例如 (string-to-number "ff" 16) ;; ⇒ 255 (string-to-number "A1") ;; ⇒ 0, 默认以10进制进行转化 (string-to-number "10" 2) ;; ⇒ 2 number-to-string 用于将数字转化为字符串,它只支持以10进制的形式转化 (nu...

如果需要处理字符串,可以将字符转换为字符串: (char-to-string ?A) (char-to-string 65) (format "%c" 65) "A" Run Code Online (Sandbox Code Playgroud) 与 (number-to-string 65) (format "%d" 65) "65" Run Code Online (Sandbox Code Playgroud)归档...
你似乎在寻找 (insert "1 2 3") 或者如果你想演示函数调用, (defun test () "1 2 3")(insert (test)) string表单需要一个字符序列,如下所示: (string ?1 ? ?2 ? ?3)=> "1 2 3" XShell 颜色高亮问题 不是。配色实际是会使用远程终端的配置;你本地 XShell 改的是当远程没有返回颜色信息时...

If optional fourth argument STRING is non-nil, it should be a string to act on; this should be the string on which the previous match was done via ‘string-match’. In this case, ‘replace-match’ creates and returns a new string, made by copying STRING and replacing the part of STRI...
