添加语法高亮IElisonBuffer [英] Add Syntax Highlighting to IElisonBuffer

问题描述

我的工作在哪里我们的 IElisonBuffers 。我有智能感知挂钩，并按下图所示的缓冲与精细其他扩展交互：

不过，我不能让语法高亮这些编辑器内工作。

我通过以下步骤嵌入这些编辑：

1. 创建一个 IVsInvisibleEditor 该文件。


2. 获得 IVsTextLines 此 IVsInvisibleEditor


3. 创建一个 IVsCodeWindow 并设置了缓冲 IVsCodeWindow 是 IVsTextLines 从 IVsInvisibleEditor


4. 从这个代码窗口获得 IWpfTextViewHost 。这使我回WPF土地里我能够与传统的跨度进行互动。


5. 创建的SnapshotSpan的 IWpfTextViewHost 的文本视图。这SnapshotSpan包含一个单一的功能。


6. 创建一个 IElisionBuffer 包含SnapshotSpan。


7. 创建一个 IVsTextBuffer 通过 IVsEditorAdaptersFactoryService.CreateVsTextBufferAdapterForSecondaryBuffer（）传入 IElisionBuffer 。


8. 现在，我投了 IVsTextBuffer 到 IVsTextLines 并调用 SetLanguageServiceID（）通过在C＃GUID：694DD9B6-B865-4C5B-AD85-86356E9C88DC


9. 我仔细检查，它是通过正确设置 GetLanguageServiceID（），一切看起来正常的。


10. 创建一个 IVsTextView 和用新的 IVsTextBuffer 。


11. 然后我得到了 IWpfTextViewHost 的初始化这个 IVsTextView 。

是否有需要被照顾任何特殊步骤？建立一个IElisionBuffer语言服务ID时

为了完整起见，这是我使用的代码：

 IVsInvisibleEditor invisibleEditor;

解决方案

请的内容类型的省音缓冲器是，或从内容类型投影派生。就是这样标注器应通过该项目的暗示。

I'm working on a project where we've split up C# code into functions and stored these functions within IElisonBuffers. I've got Intellisense hooked up, and the buffers interact with other extensions fine as shown below:

However, I cannot get syntax highlighting to work within these editors.

I embed these editors via the following steps:

1. Create an IVsInvisibleEditor for the file.
2. Get the IVsTextLines for this IVsInvisibleEditor
3. Create an IVsCodeWindow and set the buffer for this IVsCodeWindow to be the IVsTextLines from the IVsInvisibleEditor
4. Get an IWpfTextViewHost from this code window. This brings me back to "WPF Land" where I'm able to interact with traditional spans.
5. Create a SnapshotSpan of the IWpfTextViewHost's text view. This SnapshotSpan contains a single function.
6. Create an IElisionBuffer containing the SnapshotSpan.
7. Create an IVsTextBuffer via IVsEditorAdaptersFactoryService.CreateVsTextBufferAdapterForSecondaryBuffer() passing in the IElisionBuffer.
8. Now I cast the IVsTextBuffer to IVsTextLines and call SetLanguageServiceID() passing in the C# GUID: 694DD9B6-B865-4C5B-AD85-86356E9C88DC.
9. I double check that it was set correctly via GetLanguageServiceID() and everything looks alright.
10. I create an IVsTextView and initialize it with the new IVsTextBuffer.
11. I then get the IWpfTextViewHost for this IVsTextView.

Are there any special steps that need to be taken care of when setting up the language service ID for an IElisionBuffer?

For the sake of completeness this is the code I'm using:

public CustomEditorViewModel CreateEditor(string filePath, int start, int end) {

IVsInvisibleEditor invisibleEditor;
ErrorHandler.ThrowOnFailure(this._InvisibleEditorManager.RegisterInvisibleEditor(
    filePath
    , pProject: null
    , dwFlags: (uint)_EDITORREGFLAGS.RIEF_ENABLECACHING
    , pFactory: null
    , ppEditor: out invisibleEditor));

var docDataPointer = IntPtr.Zero;
Guid guidIVsTextLines = typeof(IVsTextLines).GUID;

ErrorHandler.ThrowOnFailure(
  invisibleEditor.GetDocData(
  fEnsureWritable: 1
  , riid: ref guidIVsTextLines
  , ppDocData: out docDataPointer));

IVsTextLines docData = (IVsTextLines)Marshal.GetObjectForIUnknown(docDataPointer);

//Createa a code window adapter
var codeWindow = _EditorAdapterFactory.CreateVsCodeWindowAdapter(VisualStudioServices.OLEServiceProvider);

//Associate our IVsTextLines with our new code window
ErrorHandler.ThrowOnFailure(codeWindow.SetBuffer(docData));

//Get our text view for our editor which we will use to get the WPF control that hosts that editor.
IVsTextView textView;
ErrorHandler.ThrowOnFailure(codeWindow.GetPrimaryView(out textView));

//This is our TextViewHost
//It transports us back into the land of WPF 
IWpfTextViewHost textViewHost = _EditorAdapterFactory.GetWpfTextViewHost(textView);

  //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  //Now we need to subset TextBuffer somehow... 
  //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
int length = end - start;
SnapshotSpan subsetSnapshot = new SnapshotSpan(textViewHost.TextView.TextSnapshot, start, length);

var CSharpType = _contentTypeRegistry.GetContentType("CSharp");

var projBuffer = _ProjectionBufferFactory.CreateElisionBuffer(
  null
  , new NormalizedSnapshotSpanCollection(subsetSnapshot)
  , ElisionBufferOptions.None
  ,CSharpType);

IVsTextBuffer bufferAdapter = _EditorAdapterFactory.CreateVsTextBufferAdapterForSecondaryBuffer(VisualStudioServices.OLEServiceProvider, projBuffer);

//My attempt at getting syntax coloring to work:
Guid CSharpLanguageServiceId = new Guid("694DD9B6-B865-4C5B-AD85-86356E9C88DC");
IVsTextLines buffer = (IVsTextLines)bufferAdapter;
buffer.SetLanguageServiceID(ref CSharpLanguageServiceId);


IVsTextView projTextView = _EditorAdapterFactory.CreateVsTextViewAdapter(VisualStudioServices.OLEServiceProvider);

projTextView.Initialize(
            (IVsTextLines)bufferAdapter
            , IntPtr.Zero
            , (uint)TextViewInitFlags.VIF_HSCROLL | (uint)TextViewInitFlags.VIF_VSCROLL | (uint)TextViewInitFlags3.VIF_NO_HWND_SUPPORT,
                    new[] { new INITVIEW { fSelectionMargin = 0, fWidgetMargin = 0, fVirtualSpace = 0, fDragDropMove = 0 } }
                );


 return _EditorAdapterFactory.GetWpfTextViewHost(projTextView);
}

解决方案

Make the content type of your elision buffer be, or derive from, the content type "projection". That's the hint that taggers should project through that.
