Python capture Key values ​​in a text file on OS X

Question

I am trying to track keystrokes on my Macbook to create a statistical analyzer. But how can I extract characters from an “event”, which is more 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

So, does anyone know how, based on the script presented below, to execute a .txt document with a character value (from NSEvent)? I need a text file with keys pressed to run my other script on it and analyze the frequency, etc.

Thank you in advance;)

 #!/usr/bin/python2.6 # You _must_ turn on assistive devices under Accessibility prefpane # for any of this code to work. Otherwise it won't do anything. from Cocoa import * from Foundation import * from PyObjCTools import AppHelper import keycode import string import sys class AppDelegate(NSObject): def applicationDidFinishLaunching_(self, aNotification): NSEvent.addGlobalMonitorForEventsMatchingMask_handler_(NSKeyDownMask, handler) def handler(event): if event.type() == NSKeyDown and keycode.tostring(event.keyCode()) in string.printable: print keycode.tostring(event.keyCode()) def main(): app = NSApplication.sharedApplication() delegate = AppDelegate.alloc().init() NSApp().setDelegate_(delegate) AppHelper.runEventLoop() if __name__ == '__main__': main() 

I reached out a bit and found gigub user 'gurgeh OSX to work independently in my branch - https://github.com/gurgeh/selfspy/blob/new_activity/sniff_cocoa.py .

I put some of my own ideas into this, and this is the result. Kudos to gurgeh for determining how to capture window-changing events - this makes the key logger much more interesting, since you can mostly ignore applications that do not provide interesting events, or for a statistically-minded graph of which applications you use most and what you do in them.

To use the Keycode module. Just open it here and run "sudo setup.py install". You will have a keyboard code module https://github.com/abarnert/pykeycode
