package.json

在詳細介紹vscode插件開發細節之前,這里我們先詳細介紹一下vscode插件的package.json寫法,但是建議先只需要隨便看一下,了解個大概,等后面講到具體細節的時候再回過頭來看。

如下是package.json文件的常用配置,當然這里還不是全部:

{
	// 插件的名字,應全部小寫,不能有空格
    "name": "vscode-plugin-demo",
	// 插件的友好顯示名稱,用於顯示在應用市場,支持中文
    "displayName": "VSCode插件demo",
	// 描述
    "description": "VSCode插件demo集錦",
	// 關鍵字,用於應用市場搜索
    "keywords": ["vscode", "plugin", "demo"],
	// 版本號
    "version": "1.0.0",
	// 發布者,如果要發布到應用市場的話,這個名字必須與發布者一致
    "publisher": "sxei",
	// 表示插件最低支持的vscode版本
    "engines": {
        "vscode": "^1.27.0"
    },

        "onCommand:extension.sayHello"
    ],

activationEvents

插件在VS Code中默認是沒有被激活的,哪什么時候才被激活呢?就是通過activationEvents來配置,目前支持一下8種配置:

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

都比較好懂,我就不做一一介紹了,舉個例子,如果我配置了onLanguage:javascript,那么只要我打開了JS類型的文件,插件就會被激活。

重點說一下*,如果配置了*,只要一啟動vscode,插件就會被激活,為了出色的用戶體驗,官方不推薦這么做。看到這里相信大家知道了我們前面HelloWord里面為啥要配置onCommand了吧。
