nacha

NACHA is a fixed sized record format used to represent financial transactions composed like this:

FileHeader
    CompanyBatchHeader
        EntryDetail
            EntryDetailAddendum
            ...
        ...
    CompanyBatchControl
    ...
FileControl

which we express using bryl. Writing is done like this:

with open('sample.nacha', 'w') as fo:
    writer = nacha.Writer(fo)
    with writer.begin_file(
         ...
         ):
         with writer.begin_company_batch(
              ...
              ):
             writer.entry(...):
             ...
        ...

Reading is done by iterating records like this:

with open('sample.nacha', 'r') as fo:
    reader = Reader(fo, include_terminal=True)
    for record, terminal in reader:
        ...

Or structured like this:

with open('sample.nacha', 'r') as fo:
    reader = Reader(fo)
    reader.file_header()
    for company_batch_header in reader.company_batches():
        for entry_detail, entry_addenda in reader.entries():
            ...
        reader.company_batch_control()
    reader.file_control()

use

$ pip install nacha

dev

$ git clone git@github.com:balanced/nacha.git
$ cd nacha
$ mkvirtualenv nacha
(nacha)$ pip install -e .[tests]
(nacha)$ py.test tests.py --cov=nacha --cov-report term-missing

release

Now that all tests are passing:

• Update nacha.__version__ to new {version}.
• Commit that git commit -am "Release v{version}"
• Tag it git tag -a v{version} -v v{version}
• Push it git push origin --tags

and travis will take it from there.
