自己编写了个vscode插件file-header

自己参考vsc的vscode-fileheader和vscode_extend-jsinfo扩展写了个插件
extension.ts:

'use strict';
// The module 'vscode' contains the VS Code extensibility API
// Import the module and reference it with the alias vscode in your code below
// import * as vscode from 'vscode';
let vscode=require('vscode');
let wp = vscode.workspace;

let pyComment=[
    '# @Author:${this.author}',
    '# @Date:${this.createTime}',
    '# @LastModifiedBy:${this.author}',
    '# @Last Modified time:${this.updateTime}',
    ''
];
let tjComment=[
    '/***',
    ' * @Author:${this.author}',
    ' * @Date:${this.createTime}',
    ' * @LastModifiedBy:${this.author}',
    ' * @Last Modified time:${this.updateTime}',
    ' */',
    '',
    ''
];

export function activate(context:any) {

    var config = wp.getConfiguration('fileheader');
    console.log('Congratulations, your extension "file-header" is now active!');
    console.log(config.Author);
    // 添加文件头信息
    let addFileHeader = vscode.commands.registerCommand('extension.addFileHeader', () => {
        vscode.commands.executeCommand("workbench.action.files.save");
        /**
         * 判断文件类型，使用对应格式的header注释
         */
        // let editor = vscode.editor || vscode.window.activeTextEditor;
        let editor = vscode.editor || vscode.window.activeTextEditor;
        // if(!editor){
        //     return;
        // }
        editor.edit(function(editBuilder:any){
            let dm = editor.document;
            let fileName = dm.fileName;
            console.log(fileName);
            let time = format(new Date());
            console.log(time);
            console.log(config.Author)
            let data={

            let fileCode = getFileCode(fileName);

                    for(var i=0;i<lineCount;i++){

                        lineText = lineText.trim();
                        console.log('linetext',lineText);

使用快捷键ctrl+s或ctrl+shift+y启用。
不过安装后有个bug，修改配置fileheader.Author后，不能及时同步更新，需要重新启动才行，不知道为什么。
先记录下来。
