This is standard stuff, including Data: : Dumper for debugging purposes.
这是标准的代码,包括用于调试目的的Data:Dumper。
Being prudent, you use Data: : Dumper to look at what gets read into memory and are upset to find what's seen in Listing 8.
谨慎起见,先使用Data:Dumper查看在内存中读入了什么内容,结果如清单8所示。
If you have never used Data: : Dumper, you should read the documentation (" perldoc Data: : Dumper ") and try it in your programs.
如果从没用过Data:Dumper,则应该阅读文档(“perldoc Data: Dumper ”)并在程序中尝试。
Unlike Data: : Dumper, which I've used elsewhere in autotag.pl (sometimes needlessly, I must say), print_tag_info provides a nice, user-oriented printout of the hash tag elements.
不像我在autotag . pl程序中的其他地方使用的Data:dumper函数(必须指出,有时没有必要使用),print _ tag_info函数可以提供漂亮的、面向用户的散列标签元素的打印输出。
