Clojure kebab case on selected keywords -

i want change key's in large map in clojure. these key's can present @ level in map within required-key

i looking @ using camel-snake-kebab library need change given set of keys in required-key map. doesn't matter if change made in json or map

   (def my-map {:allow_kebab_or-snake {:required-key {:must_be_kebab ""}}              :allow_kebab_or-snake2 {:optional-key {:required-key {:must_be_kebab ""}}}}) 

currently using /walk/postwalk-replace fear may change keys not nested within :required-key map

(walk/postwalk-replace {:must_be_kebab :must-be-kebab} my-map)) 

ummmm.. clarify: want change keys of map?! or associated values?

off-topic: map above not correct (having 2 identical keys :allow_kebab_or_snake - i-m assuming you're underlining point , not showing actual example :))

postwalk-replace replace occurrence of key value.

so if know exact map struct first select sub-struct get-in , use postwalk-replace :

(walk/postwalk-replace {:must_be_kebab :mus-be-kebab}                        (get-in my-map [:allow_kebab_or_snake :required-key])) 

but you'll have assoc initial map.

you should consider walk function , construct own particular algorithm if interleaved ds complex.
