Random utils, vector utilities.

get-rand-nth clj

(get-rand-nth v)

(get-rand-nth v rng)

Returns a random element of the given vector. When the second argument is present it should be an instance of random number generator used to get the random position.

merge clj

(merge v1 v2)

Merges two vectors.

of-strings clj

(of-strings coll)

(of-strings coll skip-if)

Ensures that the given collection or a single value is a non-empty vector of strings. Optional function can be given to skip matching input argument and leave it as is.

pairs clj

(pairs coll)

Partitions a vector into pairs.

rand-nths clj

(rand-nths coll)

(rand-nths coll num)

(rand-nths coll num rng)

Returns a vector with the given number of randomly selected elements of the given vector. No element will be selected more than once.

replace-by-last clj

(replace-by-last v index)

Removes an element under the given index from a vector by replacing it with the last one. For the last element index it simply removes it.

shuffle clj

(shuffle coll)

(shuffle coll rng)

Like clojure.core/shuffle but makes use of custom random number generator.

split-at clj

(split-at idx v)

Splits vector at the given index.

swap clj

(swap v index-1 index-2)

Swaps two elements of a vector.
