- 获取当前被按下的 按键 值, 支持全键盘按键, 以及鼠标 左 右 中键
- 参数说明:
- neoGetKey.exe [timeout [showMethod]]
- timeout 超时数, 单位 ms, 在运行超过此时间后自动退出, 并返回 255
- 如果 此项是 0 将一直等到检测到有键按下, 程序才会结束并返回键值.
- 如果 此项不存在, 最长将等到默认值 1000ms 后退出
- showMethod 返回值的显示方式, 此项为 D 以十进制显示, 此项为 X 以十六进制显示
- 如果此项不存在, 将不会显示返回值
- 此项 要么不指定, 否则必须和 timeout 同时指定

分别用@,-,#,$,_,},{,],[,.表示512个A、256个A、128个A、、、、、1个A,则化为:复制代码
- TVqQAAMAAAAEQAAMAAAAQAAMAAAAQAAMAAAAQAAMAAAAQAAMAAAAQAAMAAAAQAAMAAAAQAAMAAAAQAAMAAAAQAAMAAAAQAAMAAAAQAAMAAAA
然后继续迭代 用@,-,#,$,_,},{,],[,.表示512个、256个、128个、、、、、1个Q[M]则化为:复制代码
- TVqQ[M]EQ[M]Q[M]Q[M]Q[M]Q[M]Q[M]Q[M]Q[M]Q[M]Q[M]Q[M]Q[M]
用:冒号表示标签切换。化为可解码的格式复制代码
- TVq.E{]
如此就实现了用14个字符去表示108个字符的base64字符串。我发现没有任何算法有这个压缩率高。复制代码
- TVq.E{]:Q[M]:A
其中:[.;1中:[.表示要替换为的标签,分号;1表示只替换一级权签,也就是只替换.,之后的:A表示在上次替换完后再次替换所有权签为A。复制代码
