cconj clj

(cconj xs item & {:keys [size]})

circular conj adds an item into a collection, droping the last element in case a collection count is greater than a :size. (def l '(10 11 12 13 14 15 16 17)) (take 5 (iterate #(cconj % (rand-int 10) :size 10) l)) => ((10 11 12 13 14 15 16 17) (3 10 11 12 13 14 15 16 17) (9 3 10 11 12 13 14 15 16 17) (5 9 3 10 11 12 13 14 15 16) (2 5 9 3 10 11 12 13 14 15))

deep-merge-with clj

(deep-merge-with f & maps)

like merge-with, but merges maps recursively, appling the given fn only when there's a non-map at a particular level. (deepmerge + {:a {:b {:c 1 :d {:x 1 :y 2}} :e 3} :f 4} {:a {:b {:c 2 :d {:z 9} :z 3} :e 100}}) -> {:a {:b {:z 3, :c 3, :d {:z 9, :x 1, :y 2}}, :e 103}, :f 4}

dissoc-in clj

(dissoc-in m [k & ks :as keys])

from https://github.com/clojure/core.incubator

dissociates an entry from a nested associative structure returning a new nested structure. keys is a sequence of keys. Any empty maps that result will not be present in the new structure.

validate clj

(validate validators fact)

(validate validators fact {:keys [check-all?]})

takes in a sequence of validator functions and a fact to validate returns :valid if all validators pass, otherwise returns a sequence of errors

if check-all? is true, all validators will be run otherwise, validators will be run until the first error is found

example:

(defn purrs? [cat] (or (= (:purrs cat) true) {:error "cat doesn't purr"}))

(defn says-meow? [cat] (or (= (:says cat) "meow") {:error "cat doesn't say meow"}))

(defn one-tail? [cat] (or (= (:tail cat) 1) {:error "cat doesn't have 1 tail"}))

(defn four-legs? [cat] (or (= (:legs cat) 4) {:error "cat doesn't have 4 legs"}))

(validate [purrs? says-meow? one-tail? four-legs?] {:legs 3 :tail 3 :says "bow" :purrs true})

; => [{:error "cat doesn't say meow"} {:error "cat doesn't have 1 tail"} {:error "cat doesn't have 4 legs"}]

(validate [purrs? says-meow? one-tail? four-legs?] {:legs 3 :tail 3 :says "bow" :purrs true} {:check-all? false})
