I have
(def data {:headers ["A" "B" "C" "D"]
:rows [["1" "2" "3" "4"] ["5" "6" "7" "8"] ["9" "10" "11"
"12"]]})
And I have a function
(defn replace-value [struct]
(clojure.walk/prewalk-replace {"3" "hello"} (struct :rows)))
When I do
(replace-value @data) > [["1" "2" "hello" "4"] ["5" "6" "7" "8"] ["9" "10"
"11" "12"]]
which is what I am expecting.
However I want to achieve this same result using swap! So I tried
#(swap! data (replace-value %))
but I get the error #object[user$eval1308$fn__1309 0x6caeefd7
"user$eval1308$fn__1309@6caeefd7"]
I don't know what this error means nor how to resolve it
