Perhaps the best way to implement custom exception handling for all your functions, is to wrap the code inside all your event handlers such as OnEvent_Initialize or OnChatWndEvent_Created.

<code>

As you can see, despite being wrapped in other functions, the exception will still reach the try-catch block in the event handler. These are the starting points of your call stacks, so any exception occurring inside a function called from the event will bubble up in the call stack until it hits the try-catch block in your event handler code.

Javascript code:

Debugger.Catch = function(Function, Error)
{
    Debugger.Trace("/////////////////////////////////////////////////////////////////");
    Debugger.Trace("** Error in: " + Function + " **");
    Debugger.Trace("Description: " + Error.description + " (" + Error.code + ")");
    Debugger.Trace("Error time: " + new Date());
    Debugger.Trace("/////////////////////////////////////////////////////////////////");
}

Javascript code:

---

function OnEvent_Initialize(MessengerStart)
{
    try
    {
        Debugger.Call("Initialize", {"MessengerStart" : MessengerStart});
        // ...
        foo.bar(); // invalid function
    }
    catch (error)
    {
        Debugger.Catch("Initialize", error); // line 72
    }
}
