string:auto-split

说明：自动分段，按数字-字母-汉字自动断开字符串为字符串列表。不支持科学计数法的数字。

用法：

 (string:auto-split str)

参数：1 str : 字符串;

返回值：由字符串组成的列表

示例：

(string:auto-split "aa33.3bb汉字")

(defun string:auto-split (str / curr-type lst tmp% res unitp)
  "自动分段，按数字-字母-汉字自动断开字符串为字符串列表。不支持科学计数法的数字。"
  "由字符串组成的列表"
  "(string:auto-split \"aa33.3bb汉字\")"
