* Statistics of files in the execution directory (including the number of files and total lines
*
* 1. When skipping files:
* The matching rule only starts from the file name, matching The rules are also limited to the beginning.
* 2. Skip the comment lines in the file:
* The matching rules only match from the head of the comment paragraph, if // and * and # and /* appear. Lines and blank lines will be skipped. Therefore, sweaty comments like /* must be preceded by an * sign, otherwise such comments cannot be matched.
* 3、目录过滤：
* 匹配的规则是从目录名的全名匹配
