Support generation of fixed width data

[seanbehan]

This code should do it...

# Fixedwidth.generate(data: input, header: header, start: start, stop: stop, delimiter: "|") do |line|
#  output << line
# end

module Fixedwidth
  def self.generate(options)
    @options = options
    @options[:delimiter] ||= ","

    @options[:data].each do |hash|
      string = " " * (string_length*2) # FIXME: Find of end of line!
      hash.sort_by { |k,v| header_positions["#{k}"][0] }.each do |k,v|
        positions = header_positions["#{k}"]
        string[positions[0],positions[1]]="#{v}"
      end

      yield(string)
    end
  end

  def self.string_length
    column_positions.last.inject(0) { |i,sum| sum += i }
  end

  def self.header_positions
    @header_positions ||= {}.tap do |positions|
      start.zip(stop).each_with_index do |item,index|
        a, b = item[0].to_i, item[1].to_i
        a = a - 1
        b = b-a

        positions.merge!(header[index] => [a,b])
      end
    end
  end
end
