Python在OS X上的文本文件中捕获击键值 [英] Python capture Keystrokes values in text file on OS X
问题描述
我试图在Macbook上监视击键，以便构建统计分析器.但是，如何将字符与事件"隔离开呢?事件"更像是:
I am trying to monitor keystrokes on my Macbook on order to build a statistics analyzer. But how can I isolate the chars from "event" which is more something like :
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
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，有谁知道根据下面发布的脚本，如何使用chars值(来自NSEvent)来实现.txt文档?我需要一个带有按下键的文本文件，以便在其上运行其他脚本并分析频率等...
So do anyone know how to, based on the script posted below, fulfill a .txt doc with the value of chars (from NSEvent) ? I need a text file with a the pressed keys in order to run my other script on it and analyze the frequency etc...
预先感谢;)

我仔细研究了一下，发现github用户'gurgeh在自己的分支机构中对selfspy进行了OSX修改-
I dug around a bit and found github user 'gurgeh's OSX modifications for selfspy in his branch - https://github.com/gurgeh/selfspy/blob/new_activity/sniff_cocoa.py.
我在其中加入了一些自己的想法，这就是结果.弄清楚如何捕获窗口更改事件的方法值得称赞-这使按键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，或者从统计角度出发，找出使用最多的应用程序，你在他们身上做什么.
I put a few of my own ideas into it and this is the result. Kudos to gurgeh for figuring out how to capture window change events - this makes the key logger much more interesting since you could basically ignore apps that don't provide interesting events, or for the statistically minded, graph out which apps you use the most and what you're doing in them..
