【VSCode】文件模板创建及使用.md

背景

最近使用VSCode学习Vue项目比较频繁，每次创建Vue文件都要手动写重复代码，特别麻烦，就上网查找自动生成代码的说明，结果发现VSCode有代码模板，怪怪，感觉发现新大陆了(low!)。

配置

1. 打开配置

   • 方式一：首先打开File->Preferences->Configure User Snippets配置（文件->首选项->配置用户片段）：
     
   • 方式二：或通过快捷键Ctrl+Shift+P打开命令面板，输入snippets，选择Configure User Snippets：
     

2. 然后选择需要配置模板的对应文件类型（以vue模板为例，选择vue.json，其他模板同理为类型.json），如：
   
   

3. 配置自定义代码模板:

   • "Print to console" 代码模板内容
   • "prefix" 代码模板前缀，在对应类型中使用该前缀可触发根据代码模板生成代码
   • "body" 代码模板数据，实际是字符串数组
   • $1,$2,$3 代码模板变量，根据变量顺序从1开始，$0为最后一个变量，会在代码生成后输入，根据次序代表变量顺序
   • ${1:default} 代码模板变量默认值，当不输入时以默认值显示，否则显示输入值

{{// Place your snippets for vue here. Each snippet is defined under a snippet name and has a prefix, body and // description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the // same ids are connected.// Example:// "Print to console": {// 	"prefix": "log",// 	"body": [// 		"console.log('$1');",// 		"$2"// 	],// 	"description": "Log output to console"// }"Print to console":{"prefix": "vue","body": ["<template>","	<div class='${1:home}'></div>","</template>","<script>","export default {","	name: '${2:Home}',","	data() {","		return {","		}","	},","	methods: {},","};","</script>",]}
}

使用

4. 配置完成后，在VSCode中输入模板名称，按tab键即可生成模板代码，如下图所示：
