@ -62,22 +62,22 @@ Here are some examples of using Specter recursively with `recursive-path`.
## Navigate to all values in a tree
```clojure
=> (def tree-walker (recursive-path [] p (if-path vector? [ALL p] STAY)))
#'playground.specter/tree-walker
=> (def TREE-VALUES (recursive-path [] p (if-path vector? [ALL p] STAY)))
#'playground.specter/TREE-VALUES
;; Get all of the values nested within vectors
=> (select tree-walker [1 [2 [3 4] 5] [[6]]])
=> (select TREE-VALUES [1 [2 [3 4] 5] [[6]]])
[1 2 3 4 5 6]
;; Transform all of the values within vectors
=> (transform tree-walker inc [1 [2 [3 4] 5] [[6]]])
=> (transform TREE-VALUES inc [1 [2 [3 4] 5] [[6]]])
[2 [3 [4 5] 6] [[7]]]
;; Increment even leaves
=> (transform [tree-walker even?] inc [1 [2 [3 4] 5] [[6]]])
=> (transform [TREE-VALUES even?] inc [1 [2 [3 4] 5] [[6]]])
[1 [3 [3 5] 5] [[7]]]
;; Get odd leaves
=> (select [tree-walker odd?] [1 [2 [3 4] 5] [[6]]])
=> (select [TREE-VALUES odd?] [1 [2 [3 4] 5] [[6]]])
;; => [1 3 5]
;; Reverse order of even leaves (order based on depth-first search)
=> (transform (subselect tree-walker even?) reverse [1 [2 [3 4] 5] [[6]]])
=> (transform (subselect TREE-VALUES even?) reverse [1 [2 [3 4] 5] [[6]]])
[1 [6 [3 4] 5] [[2]]]
