1. 代码片段配置入口

输入：snipp
选择 Configure User Snippets

然后再选择 New Global Snippets file

输入 新建文件名称，然后按回车键。

2. 编辑代码模板

文件头和函数头模板：

{
	"FileHeader":{
		"scope": "c, cpp",
		"prefix": "demo",
		"description": "File header C/C++",
		"body": [
			"/*******************************************************************************",
			" * Copyright © XXX Technology Co., Ltd. $CURRENT_YEAR-$CURRENT_YEAR. All rights reserved.",
			"",
			" * File name:   ${TM_FILENAME/(.*)/${1:/downcase}/}",
			" * Description: THIS FILE PROVIDES ALL THE FIRMWARE FUNCTIONS.",
			" * Author:      R&D Team",
			" * Date:        $CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATE $CURRENT_HOUR:$CURRENT_MINUTE:$CURRENT_SECOND",
			" * Others:",
			" * -----------------------------------------------------------------------------",
			" * History: ",
			" * Date            Author          Modification description",
			" * ----------      ----------      -------------------------",
			" * $CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATE      Grey Luo        Create file.",
			" * $CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATE      xxxx xxx        xxxxxx xxxx.",
			" ",
			"*******************************************************************************/",
			"",
			"#ifndef _${TM_FILENAME_BASE/(.*)/${1:/upcase}/}_H_",
			"#define _${TM_FILENAME_BASE/(.*)/${1:/upcase}/}_H_",
			"",

			"#include <stdio.h>",
			"#include <stdint.h>",
			"#include <string.h>",
			"",
		
			"#include \"$TM_FILENAME_BASE.h\"",
			"","",
			"int main(void)",
			"{",
			"",
			"    return 0;",
			"}",
			"$0",
			"",
			"#endif   /* _${TM_FILENAME_BASE/(.*)/${1:/upcase}/}_H_ */"
		],
	},

	"Function":{
		"scope": "c, cpp",
		"prefix": "demo",
		"description": "Function header C/C++",
		"body": [
			"/*******************************************************************************",
			" * Function name: ModuleName_Xxxxx",
			" * Description:   This function xxxx.",
			" * Input:         a xxxxx",
			" *                b xxxxx",
			" * Output:        c xxxxx",
			" * Return:        E_OK      xxxxx",
			" *                E_NOT_OK  xxxxx",
			" * Others:",
			"*******************************************************************************/",
			"int32_t ModuleName_Xxxxx(uint8_t a, uint8_t b, uint8_t *c)",
			"{",
			"",
			"    return E_OK;",
			"}",
		],
	}
}

3. 使用代码模板

在代码编辑区输入上面配置文件里的 prefix 关键字字段值，如 “demo”，选中对应的条目，按回车键。

生成代码实际效果如下。
文件头：

函数头：
