VSCode插件开发全攻略之package.json详解

package.json

在详细介绍vscode插件开发细节之前,这里我们先详细介绍一下vscode插件的package.json写法,但是建议先只需要随便看一下,了解个大概,等后面讲到具体细节的时候再回过头来看。

如下是package.json文件的常用配置,当然这里还不是全部:

{
	// 插件的名字,应全部小写,不能有空格
 "name": "vscode-plugin-demo",
	// 插件的友好显示名称,用于显示在应用市场,支持中文
 "displayName": "VSCode插件demo",
	// 描述
 "description": "VSCode插件demo集锦",
	// 关键字,用于应用市场搜索
 "keywords": ["vscode", "plugin", "demo"],
	// 版本号
 "version": "1.0.0",
	// 发布者,如果要发布到应用市场的话,这个名字必须与发布者一致
 "publisher": "sxei",
	// 表示插件最低支持的vscode版本
 "engines": {
  "vscode": "^1.27.0"
 },
	// 插件应用市场分类,可选值: [Programming Languages, Snippets, Linters, Themes, Debuggers, Formatters, Keymaps, SCM Providers, Other, Extension Packs, Language Packs]
 "categories": [
  "Other"
 ],
	// 插件图标,至少128x128像素
 "icon": "images/icon.png",
	// 扩展的激活事件数组,可以被哪些事件激活扩展,后文有详细介绍
 "activationEvents": [
  "onCommand:extension.sayHello"
 ],
	// 插件的主入口
 "main": "./src/extension",
	// 贡献点,整个插件最重要最多的配置项
 "contributes": {
		// 插件配置项

   "type": "object",

    "vscodePluginDemo.yourName": {
     "type": "string",
     "default": "guest",
     "description": "你的名字"
    },

     "group": "navigation@6"
    },
    {
     "when": "editorFocus",
     "command": "extension.demo.getCurrentFilePath",
     "group": "navigation@5"

    },

}

activationEvents

插件在VS Code中默认是没有被激活的,哪什么时候才被激活呢?就是通过activationEvents来配置,目前支持一下8种配置:

  • onLanguage:${language}
  • onCommand:${command}
  • onDebug
  • workspaceContains:${toplevelfilename}
  • onFileSystem:${scheme}
  • onView:${viewId}
  • onUri
  • *

都比较好懂,我就不做一一介绍了,举个例子,如果我配置了onLanguage:javascript,那么只要我打开了JS类型的文件,插件就会被激活。

重点说一下*,如果配置了*,只要一启动vscode,插件就会被激活,为了出色的用户体验,官方不推荐这么做。看到这里相信大家知道了我们前面HelloWord里面为啥要配置onCommand了吧。
