A Python library to parse Cabrillo-format amateur radio contest logs, with no external dependencies.
>>> 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)For an up-to-date list of attributes to use in constructing objects
manually, see cabrillo/cabrillo.py and cabrillo/qso.py. This is helpful if your software maintains QSOs in a different database format and you are just exporting logs in the very end. For example:
>>> from cabrillo import QSO, Cabrillo
>>> from datetime import datetime
# >>> help(QSO)
# >>> help(Cabrillo)
>>> 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)
>>> cab = Cabrillo(callsign='KX0XXX', email='kx0xxx@example.com', grid_locator='AB12', soapbox=['Son of a gun!', 'DX IS!'])
>>> cab.qso.append(qso1)
>>> print(cab.text())
START-OF-LOG: 3.0
CALLSIGN: KX0XXX
EMAIL: kx0xxx@example.com
GRID-LOCATOR: AB12
CREATED-BY: cabrillo (Python)
SOAPBOX: Son of a gun!
SOAPBOX: DX IS!
QSO: 14313 PH 2018-05-30 2215 KX0XXX 59 10 CO KX9XXX 44 20 IN
END-OF-LOG:>>> # 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)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.
