开发环境配置完，就得好好琢磨开发内容了，不能老停留在hello world上呀！

一、开发文档结构分析 

1.Package.json

{
  "name": "kidtest",
  "displayName": "KidTest",
  "description": "for kid to test",
  "version": "0.0.1",
  "engines": {
    "vscode": "^1.74.0"
  },
  "categories": [
    "Other"
  ],
  "activationEvents": [
    "onCommand:kidtest.helloWorld"
  ],
  "main": "./out/extension.js",
  "contributes": {
    "commands": [
      {
        "command": "kidtest.helloWorld",
        "title": "Hello World"
      }
    ]
  },
  "scripts": {
    "vscode:prepublish": "npm run compile",
    "compile": "tsc -p ./",
    "watch": "tsc -watch -p ./",
    "pretest": "npm run compile && npm run lint",
    "lint": "eslint src --ext ts",
    "test": "node ./out/test/runTest.js"
  },
  "devDependencies": {
    "@types/vscode": "^1.74.0",
    "@types/glob": "^8.0.0",
    "@types/mocha": "^10.0.1",
    "@types/node": "16.x",
    "@typescript-eslint/eslint-plugin": "^5.45.0",
    "@typescript-eslint/parser": "^5.45.0",
    "eslint": "^8.28.0",
    "glob": "^8.0.3",
    "mocha": "^10.1.0",
    "typescript": "^4.9.3",
    "@vscode/test-electron": "^2.2.0"
  }
}

此文档里面定义的内容就是对插件的各种配置：

其中：

• "command": "case2script.helloWorld" 与 commands 中我们注册的命令 command 一致；
• "key": "ctrl+m" 为 windows 机器对应的快捷键；
• "mac": "cmd+m" 为 mac 机器对应的快捷键；
• "when": "editorFocus" 为什么时候可以调用快捷键从而可以调用插件；

when 的其他选项参考：when 的其他选项参考。

2.extension.ts 

// 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';

// This method is called when your extension is activated
// Your extension is activated the very first time the command is executed
export function activate(context: vscode.ExtensionContext) {

	// Use the console to output diagnostic information (console.log) and errors (console.error)
	// This line of code will only be executed once when your extension is activated
	console.log('Congratulations, your extension "kidtest" is now active!');

	// The command has been defined in the package.json file
	// Now provide the implementation of the command with registerCommand
	// The commandId parameter must match the command field in package.json
	let disposable = vscode.commands.registerCommand('kidtest.helloWorld', () => {
		// The code you place here will be executed every time your command is executed
		// Display a message box to the user
		vscode.window.showInformationMessage('Hello World from KidTest!');
	});

	context.subscriptions.push(disposable);
}

// This method is called when your extension is deactivated
export function deactivate() {}

 此文档涉及的就是插件的一些逻辑了，语法是Type Script(兼容JavaScript风格)。

二、插件发布

在发布之前，需要修改readme，不修改是没办法发布的

需要修改项目根目录下的 README.md 文件内容，删除 “This is the README for your extension” 

看上图，直接敲vsce package,提示找不到json文件，原因是因为路径问题，切换到对应路径即可。会有几个问题要回答，敲完，就显示done了

 发布了，还需要安装，下面这条指令进行安装，后面的是插件名称。

code --install-extension ./case2script-0.0.1.vsix 

安装完成，就可以在VScode里面看自己的杰作了。

三、写在最后

        对于一个程序员来说，此时差不多就入门了，接下来就是自己详细打磨开发过程了，这里推荐一个社区。个人觉得还不错，讲的还很详细。
