@nathanmarz Here is a test map input.

{:db
  {:active                         :left,
   :left
   {:southern                      false,
    :blocks
    [{:tame                        "first row"
      :nont                        false}]}}
 :event                            [:last-char-deleted 0]}

@frankmoyer oh, that transform should be a setval

also you should wrap (:active (:db db)) with keypath

no semantic difference but will perform better

since it doesn't have to convert keyword -> navigator at runtime

Perfect! That worked. I really appreciate it. I was just bragging to my wife about how great Specter is and how responsive you are. It makes working with Specter so much less daunting to know you are there for support!

you can also combine the two calls using (multi-path (if-path ...) nil?)

awesome, glad to help

I’m not sure I need the second call anymore now that the first call has been changed to a setval.
