Welcome! Please see the About page for a little more info on how this works.
I want to develop a tool that ingests json into native clojure data-structure and then provides a jq /json-pointer like select/map/filter api or capabilities. I believe clojure-walk might solve this.
I would not call them tutorials necessarily, but there are some examples of clojure.walk/walk and related functions like prewalk and postwalk on ClojureDocs.org here (and also follow links to related functions, or just search for them):
Note especially the prewalk-demo function: https://clojuredocs.org/clojure.walk/prewalk-demo
I wrote a tutorial on it. Do check it out.
