我正在尝试监视我的 Macbook 上的击键，以构建统计分析器。但是我怎样才能将字符与“事件”隔离开来，这更像是：

NSEvent: type=KeyDown loc=(850,248) time=66551.8 flags=0x100 win=0x0 winNum=0 ctxt=0x0 chars="l" unmodchars="l" repeat=0 keyCode=37

那么有谁知道如何根据下面发布的脚本来完成一个具有 chars 值的 .txt 文档（来自 NSEvent）？我需要一个带有按键的文本文件，以便在其上运行我的其他脚本并分析频率等...

提前致谢 ;）

我挖了一下，发现 github 用户 'gurgeh 在他的分支中对 selfspy 的 OSX 修改 - https://github.com/gurgeh/selfspy/blob/new_activity/sniff_cocoa.py。

我把一些我自己的想法放进去，这就是结果。感谢 gurgeh 弄清楚如何捕获窗口更改事件 - 这使得键盘记录器变得更加有趣，因为您基本上可以忽略不提供有趣事件的应用程序，或者对于具有统计意识的应用程序，绘制出您最常使用的应用程序和你在他们身上做什么..

用于使用 Keycode 模块。只需从这里克隆它并运行“sudo setup.py install”。您将拥有密钥代码模块 https://github.com/abarnert/pykeycode
