使幽灵return（部分）选定路径

Question

在下面的结构中，我知道如何迭代 :whatever 的所有 children 的 :x 值：

=> (specter/select
       [:whatever specter/MAP-VALS :x]
       {:whatever {:a {:x 1} :b {:x 2}}})
[1 2]

我想得到的是类似下面的内容，其中包含 wild-carded 映射键。

[[:a 1] [:b 2]]

幽灵如何做到这一点？

Answer 1

(select
        [:whatever ALL (collect-one FIRST) LAST :x]
        {:whatever {:a {:x 1}
                    :b {:x 2}
                    :c {:x 55}}})
=> [[:a 1] [:b 2] [:c 55]]

Make specter return (part of) the selected path
