primes

Fetch, locate and use prime numbers with this library. There's nothing more to it than that.

This library is designed to rapidly generate primes by being a Clojure-wrapper on top of a thread-safe Java class. You don't have to worry about anything, just ride the wave and enjoy the view. The library is stable, updates will thus be infrequent.

Usage

To use primes within your own Clojure programs and libraries, add this to your project.clj dependencies:

[com.hypirion/primes "0.2.1"]

From there, it's really easy to get working with primes. Have a look at the API for a list of different functions.

Example usage

(require '[com.hypirion.primes :as p])

(p/prime? 13)
#_=> true

(p/get 543210) ;; The 543210th prime, 0-indexed
#_=> 8054927

(p/take-below 100) ;; All primes below 100
#_=> #<UnmodifiableRandomAccessList [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 
    37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97]>

(p/take 20) ;; The 20 first primes
#_=> #<UnmodifiableRandomAccessList [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31,
    37, 41, 43, 47, 53, 59, 61, 67, 71]>

;; Lazy sequence of all primes ending with 1
(filter #(= 1 (mod % 10)) (p/primes))
#_=> (11 31 41 61 71 101 131 151 181 191 ...)
