在开发项目过程中经常需要设置设置头部注释，总是复制粘贴过于繁琐，我以python语言为例，各种语言都是相同设置方法。

打开编辑器的 文件->首选项->用户片段
弹出以下输入框,选择相应的语言.json
我选的python.json

{
// Place your snippets for python 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');",
//         "$2"
//     ],
//     "description": "Log output to console"
// }
"HEADER": {
    "prefix": "header",
    "body": [
        "#!/usr/bin/env python",
        "# -*- encoding: utf-8 -*-",
        "'''",
        // "@文件        :$TM_FILENAME",            
        "@Description:       :",
        "@Date     :$CURRENT_YEAR/$CURRENT_MONTH/$CURRENT_DATE $CURRENT_HOUR:$CURRENT_MINUTE:$CURRENT_SECOND",
        "@Author      :Javi",
        "@version      :1.0",
        "'''",
        // "",            
        // "$0"        
    ],
},
}

“prefix：header” 是快捷代码的定义
“body”数组里就是定义的内容
设置完成后重启，在相应的语言文件里 输入 定义的 header
