clojure - 让幽灵返回所选路径(部分)

Question

在以下结构中，我知道如何迭代 :whatever 的所有子级的 :x 值:

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

我想要得到的是类似下面的内容，其中包含通配符的 map 键。

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

如何用幽灵来做到这一点？

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]]
