baldr

Baldr - a god in Norse mythology, son of Odin and Frigg.

Lightweight and fast EDI X12 translator with extremely simple DSL.

Baldr supports:

• Advanced validation of structure and data types
• Multiple envelopes in a single file
• All possible separators (including non-printable characters)
• And more...

Installation

Using Bundler

gem 'baldr'

Reading

Just parse incoming message and then go over the tree (not Yggdrasil) built by Baldr:

parser = Baldr::Parser.new(File.read(file))

e = parser.envelopes.first
t = e.transactions.first

e.sender_id.should eq '4233372493'
e.receiver_id.should eq 'ODFL'

t['ST01'].should eq '204'
t.transaction_set_code.should eq '204'
t['B204'].should eq '04000000000000060'
names = t['S5'].map do |s|
  s['N101']
end
names.should eq ['SH', 'CN']

Writing

Baldr has simple syntax for building EDI messages. Something like that:

N1 do
  N101 'BT'
  N102 'AEROFLEX USA'

  N3 do
    N301 '282 Industrial Park Road'
  end

  N4 do
    N401 'Sweetwater'
    N402 'TN'
    N403 '37874'
    N404 'US'
  end

  G61 do
    G6101 'IC'
    G6102 'Local Telephone'
    G6103 'TE'
    G6104 '4233372493'
  end
end

When your transaction set is done, you can put it into X12 renderer:

separators = {
  component: '>',
  segment: "~\n",
  element: '*'
}
output = Baldr::Renderer::X12.draw(envelope, {separators: separators})

TODO

• write validators for :complex datatype
• import grammars for the rest transaction sets
• find more examples of EDI files for tests
• reading/writing components (:complex data type)
• clarify interchange version numbers
