Check your IBAN number.

iban = Iban::IbanCheck.new :iban => "PL27 1140 2004 0000 3002 0135 5387"
iban.checksum => "27"
iban.valid? => true

iban = Iban::IbanCheck.new :iban => "27 1140 2004 0000 3002 0135 5387", :country => "PL"
iban.checksum => "27"
iban.valid? => true

iban = Iban::IbanCheck.new :iban => "GB29 NWBK 6016 1331 9268 19"
iban.checksum => "29"
iban.valid? => true

iban = Iban::IbanCheck.new :iban => "IE55 AIBK 9311 5212 3456 78" # should be "IE29 AIBK 9311 5212 3456 78"
iban.checksum => "29"
iban.valid? => false

The gem will install a iban-check command to allow IBAN validation from external programs.

iban-check returns a zero exit-code if the IBAN is valid and a non-zero exit-code otherwise.

Example:

$ iban-check "GB29 NWBK 6016 1331 9268 19"
Valid IBAN
=> exit code 0

$ iban-check "XXX"
Invalid country
=> exit code 1

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
