删除存在于同级对象中并具有一定值的键 [英] remove keys that are present in sibling object and have a certain value

问题描述

我有以下输入文件:

{
    "dic": {
        "a": "",
        "b": "",
        "c": "",
        "d": ""
    },
    "remove": {
        "b": true,
        "c": false,
        "d": true
    }
}

我想用jq删除字典dic中所有同样位于值remove中的元素.

I want to remove with jq all elements of the dictionary dic which are also in the dictionary remove with the value true.

这将是输出:

{
    "dic": {
        "a": "",
        "c": ""
    },
    "remove": {
        "b": true,
        "c": false,
        "d": true
    }
}

我不确定该怎么做.我首先需要清理remove dic，仅获取值为true的键.然后，我只需要从dic删除这些键即可.

I am not sure how to do this. I would first need to clean the remove dic and only get the keys with the value true. Then I would need to somehow only delete these keys from dic.

推荐答案

除了JQ，您不需要其他任何东西.

You don't need anything other than JQ for that.

[.remove | path(.[] | select(.))] as $p | .dic |= delpaths($p)

如果remove中可能有除 true 和 false 以外的其他值，请使用

If there might be other values in remove than true and false, use

select(. == true)

代替

select(.)
