• 使用时，直接输入 .snippets文件的 prefix值 即可使用片段

.snippet文件一览

配置文件里可以使用一些变量，最常用的如$1光标首先指向位置，${1}按Tab键后光标下一个位置，${0}光标最后位置。然后还有一些变量可以使用，如文件path当前时间等

{
	// Place your global snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and 
	// description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope 
	// is left empty or omitted, the snippet gets applied to all languages. 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": {
	// 	"scope": "javascript,typescript",
	// 	"prefix": "log",
	// 	"body": [
	// 		"console.log('$1');",
	// 		"$2"
	// 	],
	// 	"description": "Log output to console"
	// }
	"myvuepage": {
		"scope": "vue",
		"prefix": "myvuepage",
		"body": [
		  "",
		  "",
		  "",
		  "",
		  ""
		],
		"description": "初始化一个 vue 文件"
	},
	"myfileurl": {
		"scope": "",
		"prefix": "myfileurl",
		"body": ["/**", "${TM_DIRECTORY}", "${1:${TM_FILEPATH}}$0", "*/"],
		"description": "查看当前文件路径"
	},
