jq - 如何修改jq中数组的每个元素

Question

假设我有一个 JSON:

[
    {
        "title": "Title1",
        "reference": [
            "123"
        ]
    },
    {
        "title": "Title2",
        "reference": [
            "234",
            "345"
        ]
    }
]

我想修改引用数组的每个元素，以便引用出现两次。我想要实现的目标:

[
    {
        "title": "Title1",
        "reference": [
            "123 is 123"
        ]
    },
    {
        "title": "Title2",
        "reference": [
            "234 is 234",
            "345 is 345"
        ]
    }
]

我已经尝试过:

jq '.[] | .reference = [("\(.reference[]) is \(.reference[])")]'

但是当数组有多个项目时，这会失败:

{
  "title": "Title1",
  "reference": [
    "123 is 123"
  ]
}
{
  "title": "Title2",
  "reference": [
    "234 is 234",
    "345 is 234",
    "234 is 345",
    "345 is 345"
  ]
}

如何修改上面的jq以达到预期的结果？

提前致谢!

Answer 1

map(.reference |= map(. + " is " + .))

将每个 .reference 更改为 .reference is .reference

[
  {
    "title": "Title1",
    "reference": [
      "123 is 123"
    ]
  },
  {
    "title": "Title2",
    "reference": [
      "234 is 234",
      "345 is 345"
    ]
  }
]
