# spectree

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.

## Leiningen

*spectree* is available from Clojars. Add the following dependency to your *project.clj*:

## Usage

```clojure

...

(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"]]]
