This library for both Clojure and ClojureScript provides an 'each' selector to use in combination with specter and tree-like data structures. It also provides the macros '+>>' and 'each+>>' to chain specter transformations.
spectree is available from Clojars. Add the following dependency to your project.clj:
...
(require '[me.lomin.spectree.hiccup])
(deftest hiccup-test
(is (= ["bash" "top"]
(specter/select (spectree/each [:hiccup/CMD :hiccup/word 1])
[:PS
[:HEADER [:word "header"]]
[:LINE
[:UID [:number "501"]]
[:PID [:number "45427"]]
[:CMD [:word "bash"]]]
[:LINE
[:UID [:number "502"]]
[:PID [:number "45428"]]
[:CMD [:word "top"]]]]))))
(deftest generic-examples-test
(is (= {:a [:x [:c 2]] :e "add-if-not-here"}
(each+>> specter/transform
:hiccup/b (constantly :x)
:e (constantly "add-if-not-here")
:must/f (constantly "not-here")
{:a [[:b 1] [:c 2]]})))
(is (= {:a 6 :b 4}
(+>> specter/transform
[:a] inc
[:b] dec
{:a 5 :b 5})))
(is (= {:a 6 :b 4 :c {:d 6 :e 4 :f [0 2 2]}}
((+>> specter/transform
[:a] inc
[:c] (+>> specter/transform
[:d] inc
[:e] dec
[:f] (+>> specter/transform
1 inc))
[:b] dec)
{:a 5 :b 5 :c {:d 5 :e 5 :f [0 1 2]}}))))
