Hey all, I'm having problems writing a zipper that can traverse a heterogeneous tree of nodes. I have i) a list of maps. Each map has ii) an :inputs key, whose value is a list of maps.
I want to use a zipper to visit each of those leaves and add a computed value. The code block and input tree data are below. I can't seem to get the zipper code to visit the leaf nodes, and add { :thing 123 }. I must be missing something simple. Any insights? A) (loop [loc (zip/zipper (or map? list?) #((if (map? %1) ;; get children of a node (:inputs %1) %1 )) #(%1) ;; create a new node (:input-layer neural-network)) ] (if (zip/end? loc) (zip/root loc) (if (map? loc) (recur (zip/next (zip/edit loc merge { :thing 123 } ))) (recur (zip/next loc)) ) ) ) B) ({:inputs ({:key :avolume, :value 2.25, :weight 0.4283380545172636, :bias 0} {:key :bvolume, :value 3.0, :weight 0.6970037374879661, :bias 0} {:key :ask, :value 1.32379, :weight 0.5387437158323669, :bias 0} {:key :bid, :value 1.3239, :weight 0.4648184032361037, :bias 0} {:key :time, :value 1.335902400676, :weight 0.43632873607404554, :bias 0}), :id "583c10bfdbd326ba34aed329139df6be2487ffc"} {:inputs ({:key :avolume, :value 2.25, :weight 0.13162215440222336, :bias 0} {:key :bvolume, :value 3.0, :weight 0.23886901184352727, :bias 0} {:key :ask, :value 1.32379, :weight 0.8408470512339872, :bias 0} {:key :bid, :value 1.3239, :weight 0.27071013797961796, :bias 0} {:key :time, :value 1.335902400676, :weight 0.6304505838898373, :bias 0}), :id "583c10bfdbd326ba34aed329139df6be2487ffd"} {:inputs ({:key :avolume, :value 2.25, :weight 0.8236972641966921, :bias 0} {:key :bvolume, :value 3.0, :weight 0.32421537754016705, :bias 0} {:key :ask, :value 1.32379, :weight 0.966306328543246, :bias 0} {:key :bid, :value 1.3239, :weight 0.8891668220470931, :bias 0} {:key :time, :value 1.335902400676, :weight 0.278993745549462, :bias 0}), :id "583c10bfdbd326ba34aed329139df6be2487ffe"} {:inputs ({:key :avolume, :value 2.25, :weight 0.27388486254027167, :bias 0} {:key :bvolume, :value 3.0, :weight 0.33659579299487363, :bias 0} {:key :ask, :value 1.32379, :weight 0.16610378593177033, :bias 0} {:key :bid, :value 1.3239, :weight 0.6964784902474896, :bias 0} {:key :time, :value 1.335902400676, :weight 0.6306732906337643, :bias 0}), :id "583c10bfdbd326ba34aed329139df6be2487fff"} {:inputs ({:key :avolume, :value 2.25, :weight 0.8819171698935051, :bias 0} {:key :bvolume, :value 3.0, :weight 0.5944805362120958, :bias 0} {:key :ask, :value 1.32379, :weight 0.9060962647355373, :bias 0} {:key :bid, :value 1.3239, :weight 0.37647418075176464, :bias 0} {:key :time, :value 1.335902400676, :weight 0.7797681719480866, :bias 0}), :id "583c10bfdbd326ba34aed329139df6be2488000"}) Thanks Tim Washington Interruptsoftware.ca 416.843.9060 -- You received this message because you are subscribed to the Google Groups "Clojure" group.
