SIE parser and generator supporting the format "SIE typ 1-4 – Klassisk SIE".

Installation

Add this line to your application's Gemfile:

gem 'sie'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sie

Generating a SIE file

To generate a SIE document you define a class that responds to the methods below. Try it out! Copy and paste this example into a ruby file and run it.

require "date"

class YourDataSource
  def program
    "Your app"
  end

  def program_version
    "1.0"
  end

  def generated_on
    Date.today
  end

  def financial_years
    [
      Date.new(2011, 1, 1)..Date.new(2011, 12, 31),
      Date.new(2012, 1, 1)..Date.new(2012, 12, 31),
      Date.new(2013, 1, 1)..Date.new(2013, 12, 31),
    ]
  end

  def company_name
    "Your company"
  end

  def accounts
    [
      { number: 1500, description: "Customer ledger" },
    ]
  end

  def balance_account_numbers
    [ 1500, 2400 ]
  end

  def closing_account_numbers
    [ 3100 ]
  end

  def dimensions
    [
      {
        number: 6,
        description: "Projekt",
        objects: [
          { number: 1, description: "Education" }
        ]
      }
    ]
  end

  # Used to calculate balance before (and on) the given date for an account.
  def balance_before(account_number, date)
    # ActiveRecord example:
    # VoucherLine.where('booked_on <= ?', date).
    # where(account_number: account_number).sum(:amount)

    0
  end

  # Used to load voucher data in batches so that you don't need to load all of
  # it into memory at once.
  def each_voucher(&block)
    [
      {
        # "creditor" and "type" is used to find the series, you can replace
        # that with "series" if the automatic lookup doesn't work for you.
        creditor: false, type: :invoice,

        number: 1, booked_on: Date.today, description: "Invoice 1",
        voucher_lines: [
          {
            account_number: 1500, amount: 512.0,
            booked_on: Date.today, description: "Item 1"
          },
          {
            account_number: 3100, amount: -512.0,
            booked_on: Date.today, description: "Item 1",
            dimensions: { 6 => 1 }
          },
        ]
      }
    ].each(&block)
  end
end

data_source = YourDataSource.new

require "sie"
doc = Sie::Document.new(data_source)
puts doc.render

For more info, see the specs.

Parsing a SIE file

You can parse sie data from anything that responds to each_line like a file or a string.

File.open("path/to/file.se") do |f|
  parser = Sie::Parser.new
  sie_file = parser.parse(f)

  # The company name
  puts sie_file.entries_with_label("fnamn").first.attributes["foretagsnamn"]

  # The first account number
  puts sie_file.entries_with_label("konto").first.attributes["kontonr"]
end

By default the parser will raise an error if it encounters unknown entry types. Use the lenient option to avoid this:

parser = Sie::Parser.new(lenient: true)

For more info, see the specs.
