Notes to Implementers

Implement this interface to create your language service. This is the primary language service interface and is required for all language services.

Examples

Here is a simple example of an implementation of this interface.

using Microsoft.VisualStudio;
using Microsoft.VisualStudio.TextManager.Interop;

namespace MyLanguagePackage
{
    class MyLanguageService : IVsLanguageInfo
    {
        public int GetCodeWindowManager(IVsCodeWindow pCodeWin,
                                        out IVsCodeWindowManager ppCodeWinMgr)
        {
            // MyCodeWindowManager class implements IVsCodeWindowManager.
            ppCodeWinMgr = new MyCodeWindowManager(pCodeWin);
            return VSConstants.S_OK;
        }


        public int GetColorizer(IVsTextLines pBuffer
                                out IVsColorizer ppColorizer)
        {
            // MyColorizer implements IVsColorizer
            ppColorizer = new MyColorizer(pBuffer);
            return VSConstants.S_OK;
        }


        public int GetFileExtensions(out string pbstrExtensions)
        {
            // This is the same extension the language service was
            // registered as supporting.
            pbstrExtensions = ".myext";
            return VSConstants.S_OK;
        }


        public int GetLanguageName(out string bstrName)
        {
            // This is the same name the language service was
            // registered with.
            bstrName = "MyLanguage";
            return VSConstants.S_OK;
        }
    }
}
