在 VSCode 扩展名中设置文本文档的语言

Question

我有一个 Visual Studio 代码扩展，我试图在其中打开一个虚拟编辑器：

vscode.workspace.openTextDocument(vscode.Uri.parse(previewSchema + ":" + path))

context.subscriptions.push(extractHibernateLogCommand, vscode.Disposable.from(
    vscode.workspace.registerTextDocumentContentProvider(previewSchema, hibernateExtractorProvider)
));

这些文档始终是 language:plain-文本。是否可以通过编程方式将此更改为 "SQL" 以获得正确的突出显示？

Answer 1

打开命令面板（查看->命令面板）
运行"Configure language specific settings"
在 Select 语言下拉菜单中应该有 SQL

的设置

Answer 2

我自己找到了解决办法：

let options: Object = {
  content: string,
  language: "sql"
};

vscode.workspace.openTextDocument(options).then(doc => {
  vscode.window.showTextDocument(doc, vscode.ViewColumn.One);
}, err => {
  vscode.window.showErrorMessage(err);
});

使用 TextDocumentContentProvider 时的解决方案似乎不可能。

Answer 3

Since VSCode 1.28 (September 2018), it's also possible to set the language mode for a document after it has been created using languages.setTextDocumentLanguage():

Set (and change) the language that is associated with the given document.

Note that calling this function will trigger the onDidCloseTextDocument event followed by the onDidOpenTextDocument event.

这是一个简单的示例，它打开包含 {} 的文档并将语言设置为 JSON:

vscode.workspace.openTextDocument({content: "{}"}).then(document => {
    vscode.window.showTextDocument(document);
    vscode.languages.setTextDocumentLanguage(document, "json");
});
