Visual Studio 2008 调试窗口显示时间戳？

发布于 2024-08-11 02:31:08 字数 346 浏览 9 评论 0原文

我希望能够在 Visual Studio 的调试窗口中的每条跟踪的开头看到时间戳。

 [此处的时间戳] 线程“Win32 Thread”(0xcd0) 已退出，代码为 0 (0x0)。

 [此处的时间戳] => CLR ProvideAssembly：AppDomainId：1，参考：'msvcm90d ...

例如 sysinternals 应用程序 - DebugView。问题是我无法进行 Visual Studio 调试，并同时使用 DebugView 进行监听，并且我不习惯将时间戳手动添加到跟踪器中。

I want to be able to see a time stamp in the beginning of every trace in the debug window in Visual studio.

 [Time stamp here] The thread 'Win32 Thread' (0xcd0) has exited with code 0 (0x0).

 [Time stamp here] => CLR ProvideAssembly: AppDomainId: 1, Ref: 'msvcm90d...

Example of this is the sysinternals application - DebugView. The problem is that I can't have Visual Studio debugging, and listening with DebugView at the same time, and I am not comfortable with adding the time stamp manually to my tracers.

由于输出窗口文本一旦写入就是只读的，因此没有一种简单的方法可以准确地执行您想要执行的操作。但是，执行类似的操作很容易：在将新文本写入输出窗口之后附加时间戳行。这将使输出窗口变得更加混乱，但你会得到你的计时。

其工作原理如下：首先，创建一个 Visual Studio 外接程序或宏，用于挂钩 PaneUpdated 事件。（请参阅此线程了解如何使用宏方法来做到这一点）。确保在事件处理程序中检查 pane.Name == "Debug" 并忽略其他窗格。其次，当您在调试输出窗格中检测到新文本时，附加一个时间戳行，如下所示：

public void AddTimestamp(DTE2 dte)
{
    // Retrieve and show the Output window.
    OutputWindow outWin = dte.ToolWindows.OutputWindow;

    pane = outWin.OutputWindowPanes.Item("Debug");
    }
    catch
    {
        pane = outWin.OutputWindowPanes.Add("Debug");
    }

    pane.OutputString("[timestamp: " + DateTime.Now.ToString() + "]\n");
}

也可以在每行前面附加一个时间戳，但这要困难得多。您无法更改“输出”窗口中已有的文本（它是只读的），但您可以清除该窗口并添加文本。因此，您可以使用上面相同的事件处理程序方法来检测文本更改，但您可以复制当前文本，将时间戳添加到任何还没有时间戳的行，清除窗口，然后重新添加 now，而不是附加- 带时间戳的文本。一旦输出窗口变大，就会出现性能问题。因此，您可能必须实现一种“惰性标记”，在后台进行清除和插入，以避免在短时间内发出 100 行调试输出（这是常见的）时杀死您的 IDE 。此外，当您清除并重新添加时，如果您当前正在输出窗口中选择文本，则您的选择将会丢失。

就我个人而言，我只会做简单的事情并附加时间戳行，而不是更困难的预挂起方法。由于如果不滚动就很难看到行末尾的内容，因此我可能会确保时间戳之前有一个换行符，因此用户会看到每批一个或多个输出行，后跟一个时间戳行。

可能有一种方法可以在显示文本之前挂钩输出窗口，但我在 VS Extensibility API 中找不到任何此类扩展点。

还有一个想法：您始终可以滚动自己的工具窗口，例如“Ivan 的调试输出”，它侦听来自真实输出窗口的事件，并将新行（带有时间戳）回显到您自己的工具窗口。这可能是最难的选择，但应该完全符合您的要求。

Since the output window text is read-only once written, there's not an easy way to do exactly what you want to do. However, it's easy to do something similar: append a timestamp line after new text is written to the output window. This will make the output window a lot more messy, but you'll get your timings.

Here's how this would work: First, create a Visual Studio Add-in or Macro which hooks the PaneUpdated event of the Outlook Window's active pane. (See this thread for how to do this with a Macro approach). Make sure to check, in the event handler, that pane.Name == "Debug" and ignore other panes. Second, when you detect new text in the debug output pane, append a timestamp line, like this:

public void AddTimestamp(DTE2 dte)
{
    // Retrieve and show the Output window.
    OutputWindow outWin = dte.ToolWindows.OutputWindow;

    pane = outWin.OutputWindowPanes.Item("Debug");
    }
    catch
    {
        pane = outWin.OutputWindowPanes.Add("Debug");
    }

    pane.OutputString("[timestamp: " + DateTime.Now.ToString() + "]\n");
}

It's also possible to pre-pend a timestamp to each line, but it's a lot harder. You can't change text already in the Output window (it's read-only), but you can clear the window and you can add text. So you could use the same event-handler approach above to detect text changes, but instead of appending you could copy the current text, prepend timestamps to any lines which don't have timestamps already, clear the window, and re-add the now-with-timestamps text. The problem with this is performance once your output window gets large. So you'd probably have to implement a kind of "lazy stamping" which does the clear and insert in the background, in order to avoid killing your IDE when (as is common) 100's of lines of debug output get emitted in a short time. Also, when you clear and re-add, if you're currently selecting text in the output window, your selection is lost.

Personally, I'd just do the easy thing and append timestamp lines rather than the harder pre-pend approach. Since stuff at the end of the line is hard to see without scrolling, I'd probably ensure there was a newline before the timestamp, so the user would see each batch of one or more output lines followed by one timestamp line.

It's possible there may be a way to hook the output window before text is displayed, but I couldn't find any such extensibility point in the VS Extensibility APIs.

One more idea: you could always roll your own tool window, e.g. "Ivan's Debug Output" which listens to events coming from the real output window, and echoes new lines (with timestamps) to your own tool window. This is probably the hardest option, but should do exactly what you want.
