我正在尝试使用 sql 的嵌入式语言支持。 rel =“ nofollow noreferrer”>请求转发机制。

根据文档，我们可以使用 Middleware 选项劫持完成，并使用现有语言服务器提供子语言完成。例如，用户可以使用此机制获得 css 语言支持 html 。

在我的情况下，我希望在编写SQL查询时获得 SQL语言在另一种语言（新语言）中支持。

示例代码

let clientOptions: LanguageClientOptions = {
  documentSelector: [{ scheme: 'file', language: '.mylang' }],
  middleware: {
    provideCompletionItem: async (document, position, context, token, next) => {
      if (
        !isInsideSQLRegion(
          myLanguageService,
          document.getText(),
          document.offsetAt(position)
        )
      ) {
        return await next(document, position, context, token);
      }

      const originalUri = document.uri.toString();
      virtualDocumentContents.set(
        originalUri,
        getSQLVirtualContent(myLanguageService, document.getText())
      );

      const vdocUriString = `embedded-content://sql/${encodeURIComponent(originalUri)}.sql`;
      const vdocUri = Uri.parse(vdocUriString);
      return await commands.executeCommand<CompletionList>(
        'vscode.executeCompletionItemProvider',
        vdocUri,
        position,
        context.triggerCharacter
      );
    }
  }
};

在这里 providecompletionItem 每次我们在编辑器中编写新字符时都会触发，但是当用户写入“

I am trying to implement embedded language support for SQL in vscode extension using request forwarding mechanism.

According to the documentation we can hijack the completion using middleware option and provide the sub-language completion using an existing language server. As an example user can get CSS language support inside HTML using this mechanism.

In my scenario, I want get SQL Language support inside another language (new language) when writing a SQL query.

Sample Code

let clientOptions: LanguageClientOptions = {
  documentSelector: [{ scheme: 'file', language: '.mylang' }],
  middleware: {
    provideCompletionItem: async (document, position, context, token, next) => {
      if (
        !isInsideSQLRegion(
          myLanguageService,
          document.getText(),
          document.offsetAt(position)
        )
      ) {
        return await next(document, position, context, token);
      }

      const originalUri = document.uri.toString();
      virtualDocumentContents.set(
        originalUri,
        getSQLVirtualContent(myLanguageService, document.getText())
      );

      const vdocUriString = `embedded-content://sql/${encodeURIComponent(originalUri)}.sql`;
      const vdocUri = Uri.parse(vdocUriString);
      return await commands.executeCommand<CompletionList>(
        'vscode.executeCompletionItemProvider',
        vdocUri,
        position,
        context.triggerCharacter
      );
    }
  }
};

Here the provideCompletionItem get triggered each time we write a new character in the editor but it seems that it is not getting triggered when user writes " or single quote.

Is there a way to get provideCompletionItem when single or double quotes is being entered ?
