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.
Just like any other gem:
gem install radix62
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"
The gem is tested against MRI 1.8/1.9/2.0/2.1, JRuby, and Rubinius. See Travis CI for details.
