作出这样的监听系统范围的快捷方式的AppleScript程序 [英] make AppleScript program that listens systemwide for shortcuts

问题描述

我想创建某种后台进程侦听所有击键事件，因此行为（例如做一些动作，如果CMD-A是pressed而在Finder.app，或更复杂的事情，比如序列创建快捷方式就像在Emacs ..）

I'd like to create some kind of background process that listens to all keystrokes event and acts consequently (for example does some action if CMD-A is pressed while in Finder.app, or more complex things, like sequences to create shortcuts like in emacs..)

但我怎么能听键presses系统范围的雪豹？
我以为AppleScript的..但没有发现任何..结果
（我擅长的红宝石也是如此，并打算用RB-appscript实际上）

But how can I listen to keypresses systemwide on SnowLeopard? I thought of Applescript.. but found nothing..
(I'm good at ruby too, and intended to use rb-appscript actually)

谢谢！

推荐答案

如果你真的想捕获所有击键系统范围内，需要<一个href=\"http://developer.apple.com/Mac/library/documentation/Carbon/Reference/QuartzEventServicesRef/Reference/reference.html#//apple_ref/c/func/CGEventTapCreate\"相对=nofollow> CGEventTap 。我不认为这是直接提供给AppleScript的，也许在10.6您可以使用 AppleScriptObjC 。当然，它应该通过<一个提供给红宝石href=\"http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/RubyPythonCocoa/Articles/GenerateFrameworkMetadata.html\"相对=nofollow>桥支持。

If you really want to capture all the keystrokes system-wide, you need CGEventTap. I don't think it's available directly to AppleScript, maybe on 10.6 you can use AppleScriptObjC. Surely it should be available to Ruby via Bridge Support.

然而，全系统的键盘听者会经常调用。我建议code C或对象 - 相反，这将是更有效的。

However, a system-wide keyboard listener would be called very often. I would suggest to code in C or Obj-C instead, which would be more efficient.
