不尚贤使民不争不贵难得之货使民不为盗不见可欲使民心不乱是以圣人之治虚其心实其腹弱其志强其骨常使民无知无欲使夫智者不敢为也为无为则无不治

开发环境MacOS(High Sierra 10.13.6 (17G65))

需要的信息和信息源：

开始编码

本篇是把ArthurSlog.com网站上的Markdown编辑器本地化了
使用的是Electron，用HTML，CSS和JavaScript来构建跨平台桌面应用程序的一个开源库
目前已经完成基本功能
完整源码已上传至 Github： github.com/BlessedChil…

git clone github.com/BlessedChil…

cd ArthurSlogMarkdownEditor

sudo npm i --unsafe-perm=true

sudo npm run start

启动rthurSlogMarkdownEditor
使用Markdown语法书写，测试成功！
对于electron来说，他主要是负责两件事情：

使用nodejs负责操作系统与界面之间的交互，称为主函数
调用浏览器渲染（例如V8、webkit、等）引擎负责界面的交互，成为渲染函数

顾名思义，主函数是一切的开始：

~/Desktop/ArthurSlogMarkdownEditor/main.js

const { app, BrowserWindow } = require('electron')

let win

function createWindow() {
    win = new BrowserWindow({
        width: 800,
        height: 600,

    })
    win.loadFile('index.html')

    //win.webContents.openDevTools()

    win.on('closed', () => {
        win = null
    })
}

app.on('ready', createWindow)

app.on('window-all-closed', () => {
    if (process.platform == 'darwin') {
        qpp.quit()
    }
})

app.on('activate', () => {
    if (win == null) {
        createWindow()
    }
})
复制代码

具体函数的作用，下次再补充了，因为我现在还有更重要的事要去做
再来看一下配置文件 package.json:

~/Desktop/ArthurSlogMarkdownEditor/package.json

  "version": "0.0.1",
  "description": "This is a Browser by Nodejs",

  "devDependencies": {

  },

  }
}
复制代码

当然，界面文件index.html也需要更新一下：
