在OS X中附加事件侦听器JavaScript for Automation（JXA）

Question

如何侦听OS X JavaScript中的事件以实现自动化？

在消息应用程序的脚本库中，有一个事件处理程序列表，如messageSent和messageReceived。但是，我无法弄清楚如何使用它们。尝试传递函数会产生错误，并尝试将这些变量设置为新函数会导致REPL挂起。

什么是设置这些事件处理程序的正确方法？

Answer 1

您将创建一个脚本，然后您可以从Preferences > General的AppleScript处理程序菜单中选择该脚本。使用内置的Speak Events.applescript文件作为您的指南，并注意您必须重写每个处理程序才能正确执行。

注：甚至用加标在内，你仍然不能因为他们是如何实现的脚本引擎之上这一层，使得使用currentApplication()看起来好像连一个合适的呼叫呼叫像say()可能脚本除了命令它正在被发送交叉应用程序。

这里是一个模板：

Messages = Application.currentApplication() 
Messages.includeStandardAdditions = true 

function messageSent(m, e) { 
} 

function messageReceived(m, e) { 
} 

function chatRoomMessageReceived(e) { 
} 

function activeChatMessageReceived(m, e) { 
} 

function addressedMessageReceived(m, b, c, e) { 
} 

function receivedTextInvitation(e) { 
} 

function receivedAudioInvitation(m, b, c, e) { 
} 

function receivedVideoInvitation(m, b, c, e) { 
} 

function receivedLocalScreenSharingInvitation(b, c, e) { 
} 

function buddyAuthorizationRequested(e) { 
} 

function addressedChatRoomMessageReceived(e) { 
} 

function receivedRemoteScreenSharingInvitation(e) { 
} 

function loginFinished(e) { 
} 

function logoutFinished(e) { 
} 

function buddyBecameAvailable(e) { 
} 

function buddyBecameUnavailable(e) { 
} 

function receivedFileTransferInvitation(e) { 
} 

function avChatStarted(e) { 
} 

function avChatEnded(e) { 
} 

function completedFileTransfer(e) { 
}

我已经得到说在OS X 10.11.3测试版（15D9c）工作。

ObjC.import('stdlib') 
var yell = "say" 

function run() { 
    // messageReceived("test",{from:Application("Messages").services.byName("SMS").buddies[0]}) 
} 

function execute(program, args) { 
    var command = program + " " + args.map(q).join("") 
    console.log(command) 
    $.system(command) 

    function q(s) { 
     return " '" + s.replace("'", "'\\''") + "' " 
    } 
} 

function messageReceived(text, who) { 
    execute(yell, [who.from.name(), text]) 
} 

function loginFinished(service) { 
    execute(yell, ["login", service.for.name()]) 
} 

function logoutFinished(service) { // doesn't work! 
    execute(yell, ["Logout", service.for.name()]) 
} 

function keys(o) { // debugging tool 
    return Object.keys(o).join(",") 
} 
receivedTextInvitation = addressedMessageReceived = chatRoomMessageReceived = activeChatMessageReceived = messageReceived 

function messageSent() {} 

function receivedAudioInvitation() {} 

function receivedVideoInvitation() {} 

function receivedLocalScreenSharingInvitation() {} 

function buddyAuthorizationRequested() {} 

function addressedChatRoomMessageReceived() {} 

function receivedRemoteScreenSharingInvitation() {} 

function logoutFinished() {} 

function buddyBecameAvailable() {} 

function buddyBecameUnavailable() {} 

function receivedFileTransferInvitation() {} 

function avChatStarted() {} 

function avChatEnded() {} 

function completedFileTransfer() {}
