Laurence build a tiny project to show washing time remaining elapse in the terminal[^1], that idea is very fun. and I was very curious about all code behind of this

Using ChatGPT to explain

首先安装 qnap 的社区版本, 注意因为 QNAP 非 root 运行, 所以现在基本上没法设置 systemctl 和 ping_group_range

论坛: https://forum.qnap.com/viewtopic.php?f=320&t=160538

安装完成后就有了 CLI, 然后根据 https://developers.cloudflare.com/cloudflare-one/tutorials/share-new-site 设置

最后更改一下 cloudflared start stop 命令 sudo vim /opt/CloudFlared/CloudFlared.sh

换一下 start stop 命令

筛选出一个 function

从以 function digga() 开头的行到 } 开头行结束

awk '/^function digga()/,/^}/' .functions

获取文本中 m3u8 链接

正则获取有 m3u8 链接行, 然后正则替换 ; 为空字符, 然后打印以 -F fs( fs 默认为 white space ) 分隔的第 4 个字符串

  ZigZag-Encoding
  ---------------
  
  Maps negative values to positive values while going back and
  forth (0 = 0, -1 = 1, 1 = 2, -2 = 3, 2 = 4, -3 = 5, 3 = 6 ...)

  (i >> bitlength-1) ^ (i << 1)

  with "i" being the number to be encoded, "^" being
  XOR-operation and ">>" would be arithemtic shifting-operation

不过，过长的代码行难以阅读，所以最好拆开来写。通常来说，当使用 .method_name() 语法调用方法时引入换行符和空格将长的代码行拆开是明智的。现在来看看这行代码干了什么。[^1]
