jolt - 我有一个简单的 json 文件，我正在尝试使用 jolt 进行转换并且遇到了问题，因为我对 jolt 很陌生

Question

这就是我想要做的： 1. 将名字和姓氏与名字连接起来 2. 将 id 更改为 employeeID 并添加员工 ID 的前缀：emp_id 3. 如果部门等于销售，则部门应该是“SL” 4. 如果部门等于销售额，比部门应该是“RET”

这是我的输入：

{
    "employees": [{
            "f_name": "tom",`
            "l_name": "smith",
            "id": "100",
            "department": "sales",
            "company": "ABC Intelligence"
        },

        {
            "f_name": "john",
            "l_name": "doe",
            "id": "102",
            "department": "returns",
            "company": "ABC Intelligence"
        }, {
            "f_name": "jane",
            "l_name": "doe",
            "id": "103",
            "department": "sales",
            "company": "ABC Intelligence"
        }
    ]
}

specs:
 [{
    "operation": "shift",
    "spec": {
        "employees": {
            "*": {

                "name": "=concat(@(1,f_name),' ',@(1,l_name))"


            }
        }
    }

},
 {
   "operation": "remove",
    "spec": {
      "employees": {
        "*": { 
          "f_name": "",
          "l_name": ""

      }
    }
  }
 }
]


desired output:

{
    "employees": [
        {
            "name": "tom smith",
            "employeeID": "emp_100",
            "department": "SL",
            "company": "ABC Intelligence"
        },
        {
            "name": "john doe",
            "employeeID": "emp_102",
            "department": "RET",
            "company": "ABC Intelligence"
        },
        {
            "name": "jane doe",
            "employeeID": "emp_103",
            "department": "SL",
            "company": "ABC Intelligence"
        }
    ]
}

我能够获得第一条规则，但仍在与其他规则作斗争。任何帮助，将不胜感激
