`beancount-dkb` provides an Importer for converting CSV exports of [DKB]
(Deutsche Kreditbank) account summaries to the [Beancount] format.

## Installation

```sh
$ pip install beancount-dkb
```

In case you prefer installing from the Github repository, please note that
`main` is the development branch so `stable` is what you should be installing
from.

## Usage

If you're not familiar with how to import external data into Beancount, please
read [this guide] first.

Adjust your [config file] to include `ECImporter` and `CreditImporter`
(depending on what account you're trying to import).

A sample configuration might look like the following:

```python
from beancount_dkb import ECImporter, CreditImporter

IBAN_NUMBER = 'DE99 9999 9999 9999 9999 99' # your real IBAN number

CARD_NUMBER = '9999 9999 9999 9999' # your real Credit Card number

CONFIG = [
ECImporter(
IBAN_NUMBER,
'Assets:DKB:EC',
currency='EUR',
),

CreditImporter(
CARD_NUMBER,
'Assets:DKB:Credit',
currency='EUR',
)
]
```

Once this is in place, you should be able to run `bean-extract` on the command
line to extract the transactions and pipe all of them into your Beancount file.

```sh
$ bean-extract /path/to/config.py transaction.csv >> you.beancount
```

### Transaction Codes as Meta Tags

By default, the ECImporter prepends the transaction code ("Buchungstext") to the
transaction description. To achieve shorter descriptions and use meta tags to
query for certain transaction codes, the importer may be configured to store the
transaction code in a user provided meta tag.

The following configuration instructs the importer to use a meta tag `code` to
store transaction codes:

```python
...
CONFIG = [
ECImporter(
IBAN_NUMBER,
'Assets:DKB:EC',
currency='EUR',
meta_code='code',
),
...

```

This is how an example transaction looks without the option:

```beancount
2021-03-01 * "Kartenzahlung" "XY Supermarket"
Assets:DKB:EC -133.72 EUR
```

And this is the resulting transaction using `meta_code='code'`

```beancount
2021-03-01 * "XY Supermarket"
code: Kartenzahlung
Assets:DKB:EC -133.72 EUR
```

### Pattern-matching Transactions

It's possible to give the importer classes hints if you'd like them to include a
second posting based on specific characteristics of the original transaction.

For instance, if the payee or the description in a transaction always matches a
certain value, it's possible to tell the `ECImporter` or `CreditImporter` to
automatically place a second posting in the returned lits of transactions.

#### `ECImporter`

`ECImporter` accepts a `payee_patterns` argument, which should be a list of
`(pattern, account)` tuples.

```python
CONFIG = [
ECImporter(
IBAN_NUMBER,
'Assets:DKB:EC',
currency='EUR',
payee_patterns=[
('REWE Filialen', 'Expenses:Supermarket:REWE'),
('NETFLIX', 'Expenses:Online:Netflix'),
],
),
```

#### `CreditImporter`

`CreditImporter` accepts a `description_patterns` argument, which should be a
list of `(pattern, account)` tuples.

```python
CONFIG = [
CreditImporter(
CARD_NUMBER,
'Assets:DKB:Credit',
currency='EUR',
description_patterns=[
('REWE sagt Danke', 'Expenses:Supermarket:REWE'),
('NETFLIX', 'Expenses:Online:Netflix'),
],
)
```
