[英]How do I write color text to the Visual Studio output window from c#?
[英]How do I write to the Visual Studio Output Window in My Custom Tool?
我正在編寫一個自定義工具,目前我正在使用它來實現我想要的功能。 如果出現問題,我希望能夠寫入 Visual Studio。 (格式不正確的代碼或其他)。
這有什么標准嗎? 現在我基本上可以強制該工具失敗,而 Visual Studio 會發出警告,說明它已經這樣做了。 我想要 Output window 中的一個類別,其中包含我要發送的任何結果消息。 我還可以接受錯誤列表 window 中更具描述性的任務/警告。
要在Visual Studio中寫入“常規”輸出窗口,您需要執行以下操作:
IVsOutputWindow outWindow = Package.GetGlobalService( typeof( SVsOutputWindow ) ) as IVsOutputWindow;
Guid generalPaneGuid = VSConstants.GUID_OutWindowGeneralPane; // P.S. There's also the GUID_OutWindowDebugPane available.
IVsOutputWindowPane generalPane;
outWindow.GetPane( ref generalPaneGuid , out generalPane );
generalPane.OutputString( "Hello World!" );
generalPane.Activate(); // Brings this pane into view
但是,如果要寫入自定義窗口,則需要執行以下操作:
IVsOutputWindow outWindow = Package.GetGlobalService( typeof( SVsOutputWindow ) ) as IVsOutputWindow;
// Use e.g. Tools -> Create GUID to make a stable, but unique GUID for your pane.
// Also, in a real project, this should probably be a static constant, and not a local variable
Guid customGuid = new Guid("0F44E2D1-F5FA-4d2d-AB30-22BE8ECD9789");
string customTitle = "Custom Window Title";
outWindow.CreatePane( ref customGuid, customTitle, 1, 1 );
IVsOutputWindowPane customPane;
outWindow.GetPane( ref customGuid, out customPane);
customPane.OutputString( "Hello, Custom World!" );
customPane.Activate(); // Brings this pane into view
有關IVsOutputWindow和IVsOutputWindowPane的詳細信息,請訪問 MSDN。
為了將項添加到錯誤列表, IVsSingleFileGenerator
有一個方法調用void Generate(...)
,其參數類型為IVsGeneratorProgress
。 此接口有一個方法void GeneratorError()
,它允許您向Visual Studio錯誤列表報告錯誤和警告。
public class MyCodeGenerator : IVsSingleFileGenerator
{
...
public void Generate( string inputFilePath, string inputFileContents, string defaultNamespace, out IntPtr outputFileContents, out int output, IVsGeneratorProgress generateProgress )
{
...
generateProgress.GeneratorError( false, 0, "An error occured", 2, 4);
...
}
...
}
可以在MSDN上找到GeneratorError()的詳細信息。
還有另一種方法使用Marshal.GetActiveObject
來獲取正在運行的DTE2
實例。
首先參考EnvDTE和envdte80。 這目前在VisualStudio 2012中有效,我還沒有嘗試過其他的。
using System;
using System.Runtime.InteropServices;
using EnvDTE;
using EnvDTE80;
internal class VsOutputLogger
{
private static Lazy<Action<string>> _Logger = new Lazy<Action<string>>( () => GetWindow().OutputString );
private static Action<string> Logger
{
get { return _Logger.Value; }
}
public static void SetLogger( Action<string> logger )
{
_Logger = new Lazy<Action<string>>( () => logger );
}
public static void Write( string format, params object[] args)
{
var message = string.Format( format, args );
Write( message );
}
public static void Write( string message )
{
Logger( message + Environment.NewLine );
}
private static OutputWindowPane GetWindow()
{
var dte = (DTE2) Marshal.GetActiveObject( "VisualStudio.DTE" );
return dte.ToolWindows.OutputWindow.ActivePane;
}
}
如果要在“輸出”窗口中顯示任何內容,則必須來自stdout。 為此,您的應用需要作為“控制台”應用進行關聯。 在項目的屬性頁面中設置/ SUBSYSTEM:CONSOLE標志,在Linker / System下將SubSystem屬性設置為CONSOLE。
在窗口中輸出輸出后,如果包含文本“錯誤:”,它將顯示為錯誤,或者如果設置“警告:”,它將顯示為警告。 如果您的錯誤文本以路徑/文件名開頭,后跟括號中的行號,則IDE會將其識別為“可單擊”錯誤,並自動導航到錯誤行。
Microsoft 示例項目中的以下幫助程序 class 對此進行了演示:
代碼如下:
using System;
using System.Diagnostics;
using Microsoft.VisualStudio.Shell.Interop;
namespace Microsoft.Samples.VisualStudio.Services
{
/// <summary>
/// This class is used to expose some utility functions used in this project.
/// </summary>
internal static class HelperFunctions
{
/// <summary>
/// This function is used to write a string on the Output window of Visual Studio.
/// </summary>
/// <param name="provider">The service provider to query for SVsOutputWindow</param>
/// <param name="text">The text to write</param>
internal static void WriteOnOutputWindow(IServiceProvider provider, string text)
{
// At first write the text on the debug output.
Debug.WriteLine(text);
// Check if we have a provider
if (null == provider)
{
// If there is no provider we can not do anything; exit now.
Debug.WriteLine("No service provider passed to WriteOnOutputWindow.");
return;
}
// Now get the SVsOutputWindow service from the service provider.
IVsOutputWindow outputWindow = provider.GetService(typeof(SVsOutputWindow)) as IVsOutputWindow;
if (null == outputWindow)
{
// If the provider doesn't expose the service there is nothing we can do.
// Write a message on the debug output and exit.
Debug.WriteLine("Can not get the SVsOutputWindow service.");
return;
}
// We can not write on the Output window itself, but only on one of its panes.
// Here we try to use the "General" pane.
Guid guidGeneral = Microsoft.VisualStudio.VSConstants.GUID_OutWindowGeneralPane;
IVsOutputWindowPane windowPane;
if (Microsoft.VisualStudio.ErrorHandler.Failed(outputWindow.GetPane(ref guidGeneral, out windowPane)) ||
(null == windowPane))
{
if (Microsoft.VisualStudio.ErrorHandler.Failed(outputWindow.CreatePane(ref guidGeneral, "General", 1, 0)))
{
// Nothing to do here, just debug output and exit
Debug.WriteLine("Failed to create the Output window pane.");
return;
}
if (Microsoft.VisualStudio.ErrorHandler.Failed(outputWindow.GetPane(ref guidGeneral, out windowPane)) ||
(null == windowPane))
{
// Again, there is nothing we can do to recover from this error, so write on the
// debug output and exit.
Debug.WriteLine("Failed to get the Output window pane.");
return;
}
if (Microsoft.VisualStudio.ErrorHandler.Failed(windowPane.Activate()))
{
Debug.WriteLine("Failed to activate the Output window pane.");
return;
}
}
// Finally we can write on the window pane.
if (Microsoft.VisualStudio.ErrorHandler.Failed(windowPane.OutputString(text)))
{
Debug.WriteLine("Failed to write on the Output window pane.");
}
}
}
}
您可以使用Debug和/或Trace類。 這里有一些信息: http : //msdn.microsoft.com/en-us/library/bs4c1wda(VS.71).aspx
祝你好運。
