在 Visual Studio 中以特定行号打开文件 [英] Open a file in Visual Studio at a specific line number

问题描述

我有一个实用程序 (grep)，它为我提供了一个文件名列表和一个行号.在确定 devenv 是打开文件的正确程序之后，我想确保它在指定的行号处打开.在 emacs 中，这将是:

I have a utility (grep) that gives me a list of filenames and a line numbers. After I have determined that devenv is the correct program to open a file, I would like to ensure that it is opened at the indicated line number. In emacs, this would be:

emacs +140 filename.c

我在 Visual Studio (devenv) 中没有发现任何类似的东西.我找到的最接近的是:

I have found nothing like this for Visual Studio (devenv). The closest I have found is:

devenv /Command "Edit.Goto 140" filename.c

但是，这为每个此类文件创建了一个单独的 devenv 实例.我宁愿拥有使用现有实例的东西.

However, this makes a separate instance of devenv for each such file. I would rather have something that uses an existing instance.

这些变体重复使用现有的 devenv，但不要转到指示的行:

These variations re-use an existing devenv, but don't go to the indicated line:

devenv /Command "Edit.Goto 140" /Edit filename.c
devenv /Command  /Edit filename.c "Edit.Goto 140"

我认为使用多个/Command"参数可能会做到这一点，但我可能没有正确的参数，因为我要么收到错误要么根本没有响应(除了打开一个空的 devenv).

I thought that using multiple "/Command" arguments might do it, but I probably don't have the right one because I either get errors or no response at all (other than opening an empty devenv).

我可以为 devenv 编写一个特殊的宏，但我希望没有该宏的其他人也可以使用该实用程序.而且我不清楚如何使用/Command"选项调用该宏.

I could write a special macro for devenv, but I would like this utility to be used by others that don't have that macro. And I'm not clear on how to invoke that macro with the "/Command" option.

有什么想法吗?

好吧，似乎没有办法按照我的意愿执行此操作.由于看起来我需要专门的代码来启动 Visual Studio，我决定使用 EnvDTE，如下所示.希望这会对其他人有所帮助.

Well, it doesn't appear that there is a way to do this as I wanted. Since it looks like I'll need to have dedicated code to start up Visual Studio, I've decided to use EnvDTE as shown below. Hopefully this will help somebody else.

        return false;

    CComPtr<IDispatch> selection_dispatch;
    result = doc->get_Selection(&selection_dispatch);

        return false;

    CComPtr<EnvDTE::TextSelection> selection;
    result = selection_dispatch->QueryInterface(&selection);
    if (FAILED(result))
        return false;

    result = selection->GotoLine(line, TRUE);
    if (FAILED(result))
        return false;

    return true;
}

推荐答案

我想不出用直接的命令行选项来做这件事的方法.看起来您必须为它编写一个宏.据说，您可以像这样调用它们.

I can't figure out a way to do this with straight command-line options. It looks like you will have to write a macro for it. Supposedly, you can invoke them like so.

devenv /command "Macros.MyMacros.Module1.OpenFavoriteFiles"

因此，您可以创建一个宏，它接受文件名和行号，然后打开文件并跳转到正确的位置.但是，我不知道您是否可以在某处指定相同实例标志.

So, you can probably create a macro that takes a filename and a line number, then opens the file and jumps to the proper place. But, I don't know that you can specify a same-instance flag somewhere, or not.
