获取当前文档vscode的文件扩展名

Question

我正在编写一个vscode扩展名，它接受当前的文件类型，并为它生成一个HelloWorld初学者代码。但是，我无法找到如何在vscode文档中获取当前文件类型，找到的任何代码都无法工作。我们会感谢你的帮助。当前代码在生成相关代码之前接受文件名，然后接受fileType。

        const documentFileType = null;
        const documentFileName = vscode.window.activeTextEditor?.document.fileName;

        if documentFileType === 'ts' {
            vscode.window.activeTextEditor.edit(editBuilder => {
                editBuilder.insert(new vscode.Position(0, 0), 'console.log("Hello World!");');
            });
        }

如果有人想看的话..。

import * as vscode from 'vscode';
import "typescript";

export function activate(context: vscode.ExtensionContext) {
    console.log("code-boilerplate is active!");
    
    let disposable = vscode.commands.registerCommand('code-boilerplate.CodeBoilerPlate', () => {
    
        const documentFileType = null;
        const documentFileName = vscode.window.activeTextEditor?.document.fileName;

        if documentFileType === 'ts' {
            vscode.window.activeTextEditor.edit(editBuilder => {
                editBuilder.insert(new vscode.Position(0, 0), 'console.log("Hello World!");');
            });
        }
        else if documentFileType == "py" {
            vscode.window.activeTextEditor.edit(editBuilder => {
                editBuilder.insert(new vscode.Position(0, 0), 'print("Hello World!")');
            });
        }
        else if documentFileType === "js" {
            vscode.window.activeTextEditor?.edit(editBuilder => {
                editBuilder.insert(new vscode.Position(0,0), 'console.log("Hello World!")');
            })
        }
        
            vscode.window.showInformationMessage("Generating code boilerplate...");
    });

    context.subscriptions.push(disposable);
}

// this method is called when your extension is deactivated
export function deactivate() {
    console.log("code-boilerplate is deactivated!");
}

可以使用vscode.window.activeTextEditor?.document.languageId获取当前文档的语言。
