这里以创建一个 javascript 代码片段为例：
1、首先可以打开一个javascript的文件(或在当前打开文件中)按快捷键ctrl+shift+p打开命令输入 snippet : (也可以点击文件=>首选项=>用户代码片段)
2、选择选项后会出现一个语言列表用以选择给哪种语言创建代码段。这里以设置javascript的console.writeline代码段为例，其他语言方法是一样的。
选择javascript后会自动打开一个json格式的配置文件
{ // place your snippets for javascript 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" // },}
根据自身需要修改内容如下：
{ // place your snippets for javascript 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: "page header": { "prefix": "ducx", "body": [ "/**", " * $1", " * ", " * @author ducx", " * @created $current_year/$current_month/$current_date $current_hour:$current_minute:$current_second", " */", "$2" ], "description": "page header" }}
保存之后，打开一个 js 文件，输入前缀 ducx 出现快捷提示窗后回车，此时已经生成了我们自定义的代码片段结构，依次按 tab 。
/** * * * @author ducx * @created 2018/08/31 17:08:37 */
