KtoBlzCheck

KtoBlzCheck is a small Ruby extension for Linux (written in C) that provides an interface for libktoblzcheck, a library to check German account numbers and bank codes. It further provides a simple query method to find bank codes, locations and names

Huge chunks of this RubyGem is based on the original Ruby/C implementation rbKtoBlzCheck by Kim Rudolph.

Installation

You'll need

• Ruby v1.9.3 or higher (if you still run Ruby 1.8, use rbKtoBlzCheck)
• and libktoblzcheck (the package name may vary).

Add this line to your application's Gemfile:

gem 'ktoblzcheck'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ktoblzcheck

If you get a warning like Couldn't find header file ktoblzcheck.h, make sure you have libktoblzcheck installed. You can either fetch this library from SourceForge or install it on Debian/Ubuntu with

# apt-get install -y libktoblzcheck1c2a libktoblzcheck1-dev

You can verify the installation e.g. by calling locate ktoblzcheck.h—this should point to an existing file.

Usage

require 'ktoblzcheck'

@bank_code  = "20030700"
@account_no = "0"

puts "Testing Bank Code: #{@bank_code} / Account No. #{@account_no}"

KtoBlzCheck.new do |kbc|
  name, location = kbc.find(@bank_code)
  if name
    puts "Bank found! #{name} located in #{location}"
  else
    puts "Bank not found!"
  end
  case kbc.check(@bank_code, @account_no)
  when KtoBlzCheck::ERROR
    puts "Failed, bank code and account number don't match"
  when KtoBlzCheck::OK
    puts "Success, valid combination of bank code and account number"
  when KtoBlzCheck::UNKNOWN
    puts "Unknown."
  when KtoBlzCheck::BANK_NOT_KNOWN
    puts "Unknown bank code"
  else
    puts "Never reached :)"
  end
end
