Usage

Basic parsing:

import mt940
import pprint

transactions = mt940.parse('mt940_tests/jejik/abnamro.sta')

print('Transactions:')
print(transactions)
pprint.pprint(transactions.data)

print()
for transaction in transactions:
    print('Transaction: ', transaction)
    pprint.pprint(transaction.data)

Set opening / closing balance information on each transaction:

import mt940
import pprint

mt940.tags.BalanceBase.scope = mt940.models.Transaction

# The currency has to be set manually when setting the BalanceBase scope to Transaction.
transactions = mt940.models.Transactions(processors=dict(
    pre_statement=[
        mt940.processors.add_currency_pre_processor('EUR'),
    ],
))

with open('mt940_tests/jejik/abnamro.sta') as f:
    data = f.read()

transactions.parse(data)

for transaction in transactions:
    print('Transaction: ', transaction)
    pprint.pprint(transaction.data)

Simple json encoding:

import json
import mt940


transactions = mt940.parse('mt940_tests/jejik/abnamro.sta')

print(json.dumps(transactions, indent=4, cls=mt940.JSONEncoder))

Parsing statements from the Dutch bank ASN where tag 61 does not follow the Swift specifications:

def ASNB_mt940_data():
    with open('mt940_tests/ASNB/0708271685_09022020_164516.940.txt') as fh:
        return fh.read()

def test_ASNB_tags(ASNB_mt940_data):
    tag_parser = mt940.tags.StatementASNB()
    trs = mt940.models.Transactions(tags={
        tag_parser.id: tag_parser
    })

trs.parse(ASNB_mt940_data)
trs_data = pprint.pformat(trs.data, sort_dicts=False)
print(trs_data)

Contributing

Help is greatly appreciated, just please remember to clone the development branch and to run tox before creating pull requests.

Travis tests for flake8 support and test coverage so it's always good to check those before creating a pull request.

Development branch:

To run the tests:

pip install -r mt940_tests/requirements.txt
py.test

Or to run the tests on all available Python versions:

pip install tox
tox
