A Clojure library for convering numbers into short alphanumeric IDs.
The number is coverted to an alphanumeric string and back using the encode the decode functions respectively. The functions accept the dictionary as their first parameter and the value as the second.
Helper functions are provided for the following dictionary sizes:
encode-16/decode-16encode-32/decode-32encode-64/decode-64encode-89/decode-89
Using a larger dictionary results in a shorter ID being generated.
(use 'alpha-id.core)
(def dict [\0 \1 \2 \3 \4 \5 \6 \7 \8 \9 \A \B \C \D \E \F])
(encode dict 123456) ;=> "1E240"
(decode dict "1E240") ;=> 123456
(encode-64 9007199254740992) ;=>"fFgnDxSe8"
(decode-64 "fFgnDxSe8") ;=> 9007199254740992Copyright © 2015 Dmitri Sotnikov
