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)
