如何通过vscode扩展命令激活文档？

npm install -g yo generator-code
yo code

const vscode = require('vscode');

function activate(context) {
    let disposable = vscode.commands.registerCommand('extension.activateDocument', function () {
        // 获取当前活动文档
        const editor = vscode.window.activeTextEditor;
        if (editor) {
            const document = editor.document;
            // 在这里处理文档激活逻辑
            vscode.window.showInformationMessage(`激活文档: ${document.fileName}`);
        } else {
            vscode.window.showInformationMessage('没有活动的文本编辑器');
        }
    });

    context.subscriptions.push(disposable);
}

exports.activate = activate;
