This is a library to parse MT940 account statements. It was ported from Ruby and is based on
[Thies C. Arntzen's mt940 library](https://github.com/betterplace/mt940_parser).
MT940 is a standard structured customer statement message format developed by SWIFT. It is an
end-of-day statement file which details all entries booked to a bank account.

## Basic usage

Include a dependency in your `mix.exs`:

```elixir
deps: [{:mt940, "~> 0.4.1"}, …]
```

`use MT940` and `parse!` the raw input:

```elixir
defmodule BankAccount do
  use MT940

  def balance(raw) when is_binary(raw) do
    %{amount: amount, currency: currency} = raw
    |> parse!
    |> Enum.at(-1)
    |> MT940.CustomerStatementMessage.closing_balance
    "#{amount} #{currency}"
  end

  def transactions(raw) when is_binary(raw) do
    raw
    |> parse!
    |> Enum.flat_map(&MT940.CustomerStatementMessage.statement_lines/1)
  end
end
```

If you want to have a more detailed, low-level list of MT940 commands, use the
`MT940.Parser.parse!` command.
