A Python library to parse Cabrillo-format amateur radio contest logs.

Project description

cabrillo Build Status

A Python library to parse Cabrillo-format amateur radio contest logs.

Getting Started

Basic Parsing

>>> from cabrillo.parser import parse_log_file
>>> cab = parse_log_file('tests/CQWPX.log')
>>> cab.callsign
'AA1ZZZ'
>>> cab.qso
[<cabrillo.qso.QSO object at 0x10cb09f28>, <cabrillo.qso.QSO object at 0x10cbc8860>]
>>> cab.text()
'START-OF-LOG: 3.0\nCREATED-BY: WriteLog V10.72C\nCALLSIGN: AA1ZZZ\n[...snip...]END-OF-LOG:\n'

You can also write to a file:

with open('out.cbr', 'w') as o:
    cab.write(o)

The same works for text-file-like objects.

Finally, if you desire to parse Cabrillo data already present as a Python string, you can do so with, e.g.,

from cabrillo.parser import parse_log_text

cabrillo_text = """START-OF-LOG: 3.0
END-OF-LOG:
"""

cab = parse_log_text(cabrillo_text)

Ignoring malorder

Cabrillo logs must be time-sorted. If you want to read files that are not so sorted, but other than that are Cabrillo files, you can do so by adding a keyword argument ignore_order=False to either parse_log_file or parse_log_text. If you do that, the resulting Cabrillo object will refuse to generate (potentially non-)Cabrillo output.

Matching Two QSOs in Contest Scoring

>>> # We start off with a pair with complementary data.
>>> from cabrillo import QSO
>>> from datetime import datetime
>>> qso1 = QSO('14313', 'PH', datetime.strptime('May 30 2018 10:15PM', '%b %d %Y %I:%M%p'), 'KX0XXX', 'KX9XXX', de_exch=['59', '10', 'CO'], dx_exch=['44', '20', 'IN'], t=None)
>>> qso2 = QSO('14313', 'PH', datetime.strptime('May 30 2018 10:10PM', '%b %d %Y %I:%M%p'), 'KX9XXX', 'KX0XXX', de_exch=['44', '20', 'IN'], dx_exch=['59', '10', 'CO'], t=None)
>>> qso1.match_against(qso2)
True
>>> qso1.freq = '14000'  # Same band, still will match.
>>> qso1.match_against(qso2)
True
>>> qso1.match_against(qso2, max_time_delta=1)  # Make time checking less lenient.
False
>>> # All flags.
>>> qso1.match_against(qso2, max_time_delta=30, check_exch=True, check_band=True)

Contributors

Pull requests are appreciated!

The following instructions show how to obtain the sourcecode and execute the tests. They assume Python 3.3 or later.

For Posix plattforms (which includes Mac and Linux):

git clone https://github.com/thxo/cabrillo.git
cd cabrillo
python3 -m venv python-venv
source python-venv/bin/activate
pip install -r requirements_test.txt
py.test --cov-report term-missing --cov cabrillo -v

On a Windows machine, using cmd.exe, substitute python-venv/Scripts/activate for source python-venv/bin/activate.
