Clojurians Log v2

I have a nested structure, combining vectors and maps like this:

[{:__type "some_type"
  :mykey 1
  :date    #inst"..."
  :subs [{__type "another_type"
          :typekey "value"}
         {__type "another_type"}]
  :onesub {:__type "random_type"
           :subkey 2}]}

how would I do that using specter (I guess specter is the best way to do it 🙂 )

it has to be some recursive path, but I can't really figure out how it would look like, so: (specter/transform [....?] resolve m)

with resolve the function to apply to the values that have to be transformed, but what is ...??

so, this is what I came up with so far for one type:

(defn type-map-path [__type]
	(specter/recursive-path [] p
                        [(specter/walker #(= (:__type %) __type))
                         (specter/stay-then-continue [specter/ALL p])]))

(def SOME-TYPE-MAP-PATH (type-map-path "some_type"))
(def SOME-TYPE-KEYS-PATH (specter/multi-path :date :name))

Just wondering looping and walking several times would bring much benefit over trying to make multi-path work for different __types

@kurt-o-sys this is a better way to do it:

(def MAPS
  (recursive-path [] p
    (cond-path
      map? (continue-then-stay MAP-VALS p)
      coll? [ALL p])
    ))

(transform [MAPS #(= (:__type %) "another_type")] resolve data)

walker is very wasteful in this case, since it traverses into map keys and key/value pairs

this is a much more efficient way to navigate your data structure that leverages the structure of your data

oh, nice, thx!

I'm starting to really fall in love with specter 😛

Hi everyone. I'm trying to add Specter to a lein clojure project. I've added [com.rpl/specter "1.1.0"] to my dependencies and (:require [com.rpl.specter]) to my ns. I'm getting the following error in my ns thought: FileNotFoundException Could not locate com/rpl/specter__init.class or com/rpl/specter.clj on classpath. clojure.lang.RT.load (RT.java:463).

@yogidevbear are you in a REPL?

I'm working from within ProtoREPL doing inline evaluation inside atom io

okay, I don’t know how that works unfortunately

try running lein deps inside your project and see if that helps

No luck

@yogidevbear you're best off asking in #clojurescript

Hmmm, but I'm not using ClojureScript

oh sorry, misunderstood

does it work from lein repl?

Yup, seems to work if I do (use 'com.rpl.specter) from within lein repl

have you tried restarting protorepl?

I'll give that a try

would it be worth clearing out my .m2 folder too?

doubtful given that it's working with a regular repl

Fair point 🙂
