QuickLog

QuickLog is a tiny Python3 library for logging experimental results. It uses JSON to serialize log records into human readable text files. Appending new records to a log file does not require parsing the current log data, making logging performance scallable. Parsing log results may however require some time, but complexity is $O(n)$ where n is the number of records in the log file.

QuickLog also features trace save to a traces database (which is a structured directory). Each trace is referenced in the log file via a unique random identifier. For this, the TRACESDIR environment variable should refer to the traces database directory. If this environment variable is not defined, ./traces directory is used.

This library is meant to be very simple to use.

Logging example

import quicklog

log = quicklog.Log()
for i in range(100):
    # new_record creates a dict with session Id, record Id and timestamp.
    record = quicklog.new_record()
    # Add experiment data
    record['result'] = do_experiment()
    log.append(record)

Parsing log example

import quicklog

for record in quicklog.read_log():
    rid = record['id']
    result = record['result']
    print(f'{rid}: {result}')
