Introduction to Loggalot

Loggalot is a powerful logging library designed for developers looking to incorporate comprehensive logging functionality into their applications. It provides a wide range of APIs for various logging needs, from basic logging to more advanced features.

Basic Logging

Loggalot allows you to perform simple logging with easy-to-use methods. Below is an example of basic log creation:

  import loggalot
# Create a logger instance logger = loggalot.get_logger('my_logger')
# Log a simple message logger.info('This is a basic log message')  

Advanced Logging

For more advanced logging needs, Loggalot offers methods such as:

  # Log a warning message logger.warning('This is a warning log message')
# Log an error message logger.error('This is an error log message')
# Log a debug message logger.debug('This is a debug log message')  

Conditional Logging

Log only when conditions are met:

  # Log an event if a certain condition is true if my_condition:
    logger.info('Condition met, logging event')
 

Structured Logging

Produce more detailed logs with structured data:

  # Log with structured data logger.info('User login', extra={'user': 'John Doe', 'status': 'success'})  

Exception Logging

Automatically log exceptions with integrated error handling:

  try:
    # Code block that may raise an exception
    risky_operation()
except Exception as e:
    logger.exception('An error occurred')
 

Log Rotation

Implement log file rotation to manage log file sizes:

  from loggalot.handlers import RotatingFileHandler
# Set up rotating file handler handler = RotatingFileHandler('app.log', maxBytes=1024, backupCount=3) logger.addHandler(handler)  

Filter Logs

Filter logs to capture specific types of log messages:

  class CustomFilter(loggalot.Filter):
    def filter(self, record):
        return 'important' in record.msg

logger.addFilter(CustomFilter())  

Log Formatting

Customize log message formats:

  formatter = loggalot.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s') handler.setFormatter(formatter)  

Application Example

Let’s integrate these APIs into a real-world example:

  import loggalot from loggalot.handlers import RotatingFileHandler
def create_logger(name):
    logger = loggalot.get_logger(name)
    handler = RotatingFileHandler('app.log', maxBytes=1024, backupCount=3)
    formatter = loggalot.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
    handler.setFormatter(formatter)
    logger.addHandler(handler)
    return logger

def main():
    logger = create_logger('app_example')
    logger.info('Application started')

    try:
        # Application logic
        logger.debug('Debug message with details')
        result = 10 / 0  # This will raise an exception
    except Exception as e:
        logger.exception('Caught an exception')

    logger.info('Application ended')

if __name__ == '__main__':
    main()
 

By leveraging Loggalot’s robust API, we can efficiently manage logging across various scenarios, making it a valuable tool for any developer’s toolkit.
