gem install *.gem

Usage

require 'iso/iban'
ISO::IBAN.valid?('CH35 1234 5987 6543 2109 A')       # => true
ISO::IBAN.validate('CH37 1234 5987 6543 2109 A')     # => [:invalid_checksum]
ISO::IBAN.generate('CH', '12345', '987')             # => #<ISO::IBAN CH76 1234 5000 0000 0098 7>
iban = ISO::IBAN.parse('CH35 1234 5987 6543 2109 A') # => #<ISO::IBAN CH35 1234 5987 6543 2109 A>
iban = ISO::IBAN.new('CH351234598765432109A')        # => #<ISO::IBAN CH35 1234 5987 6543 2109 A>
iban.formatted       # => "CH35 1234 5987 6543 2109 A"
iban.compact         # => "CH351234598765432109A"
iban.country         # => "CH"
iban.checksum_digits # => "35"
iban.bank_code       # => "12345"
iban.account_code    # => "98765432109A"
iban.valid?          # => true
iban.validate        # => []

Note: iso/iban automatically loads the IBAN specifications delivered with the gem. If you do not wish those to be loaded, require 'iso/iban/no_autoload' instead.

ENV

ISO::IBAN.load_specifications (which is automatically called when you require 'iso/iban') uses the ENV variable IBAN_SPECIFICATIONS to determine where to look for IBAN specifications. If that variable is not set, it will default to the datafile delivered with the gem.
