macros - How to use defmacro instead of eval? -

-

i have come below function, works intended uses eval horrible, , not exist in clojurescript intend use it.

(defn path [d p]   (eval      (concat '[-> d]        (flatten (map                   #(conj (repeat (dec %) 'z/right) 'z/down)                   (path-to-vector p))))))

how convert macro? attempt looks this:

(defmacro path [d p]   `(concat (-> ~d)       (flatten        (map #(conj (repeat (dec %) z/right) z/down)              (path-to-vector ~p)))))

but not work.

no need macro or eval, operation reduce:

(defn path [d p]   (reduce (fn [s v]             (reduce #(%2 %1) s (conj (repeat (dec v) z/right) z/down)))           d (path-to-vector p)))

also note (conj (repeat (dec %) z/right) z/down) means z/down , z/right coz repeate return sequence, in case want z/right first , last item should z/down should use (conj (vec (repeat (dec %)) z/right) z/down)
