Radix62

Convert integers to base 62 strings and back.

Base 62 includes the numbers 0-9 and characters A-Z (both lower and upper case). This can be useful for applications such as URL shorteners.

Installation

Just like any other gem:

gem install radix62

Usage

Two methods are provided, Radix62#encode62 and Radix62#decode62

require "radix62"
Radix62.encode62(1000)                          #=> "g8"
Radix62.encode62(9999999)                       #=> "FXsj"
Radix62.decode62("a")                           #=> "10"
Radix62.decode62("A")                           #=> "36"
Radix62.decode62("Abc123")                      #=> "33146185555"
Radix62.decode62(Radix62.encode62(1234567890))  #=> 1234567890

Radix62 also adds the decode62 and encode62 convenience methods to the String and Integer classes, respectively.

1000.encode62                                   #=> "g8"
"Abc123".decode62                               #=> "33146185555"
