VSCode代码片段配置

1.在VSCode设置 > 配置用户代码片段菜单添加

 2.在输入框中选择新建代码片段

3.输入代码片段名称.例如:copyright

4. 生成第3步名称的代码片段文件,默认位置:C:\Users\你的电脑名称\AppData\Roaming\Code\User\snippets

5. 代码片段模板的解释如下: 重点关注scope+prefix+body参数的配置,

        5.1 scope是代码片段适用的语言, 不配置则默认适用所有语言

        5.2 prefix 前缀,也就是快捷指令,在编辑器中输入快捷指令即可快速加载出该代码片段

        5.3 body 也就是代码片段的内容, 支持环境变量及可选入参

 6. 根据模板编写代码片段后保存,body中支持换行符 制表符等特殊字符

7.在编辑区域即可通过prefix 中配置的快捷指令来快速插入body中的内容

 8. body中关于变量的用法
