Welcome to lx-logger: The Ultimate Logging Solution

Logging is a crucial aspect of software development, providing insights into the operation of your application. lx-logger offers a robust and flexible logging system that can be customized to meet a variety of needs.

Getting Started with lx-logger

Before diving into the API, let’s initialize lx-logger:

  from lx_logger import Logger

  # Initialize the logger
  logger = Logger('app.log', level='DEBUG')

Key APIs and Examples

Basic Logging

The most fundamental logging function:

  logger.info('This is an information message.')
  logger.debug('This is a debug message.')
  logger.error('This is an error message.')

Custom Logging Levels

Define and use custom logging levels:

  logger.addLevel('TRACE', 5)
  
  logger.trace('This is a trace message.')

Formatted Messages

Utilizing formatted strings in log messages:

  user_id = 123
  logger.info('User {user_id} logged in.'.format(user_id=user_id))

Exception Logging

Log exceptions efficiently:

  try:
    1 / 0
  except ZeroDivisionError as e:
    logger.exception('An error occurred:', e)

Rotating Log Files

Manage log file sizes and rotations:

  from lx_logger.handlers import RotatingFileHandler
  
  handler = RotatingFileHandler('app.log', maxBytes=10000, backupCount=3)
  
  logger = Logger('app.log', level='DEBUG', handler=handler)

Asynchronous Logging

Improve performance with asynchronous logging:

  from lx_logger.handlers import AsyncHandler
  
  handler = AsyncHandler(RotatingFileHandler('app.log', maxBytes=10000, backupCount=3))
  
  logger = Logger('app.log', level='DEBUG', handler=handler)

Sample Application Using lx-logger

Integrating lx-logger into a simple application:

  from lx_logger import Logger
  from lx_logger.handlers import RotatingFileHandler

  # Initialize the logger
  handler = RotatingFileHandler('app.log', maxBytes=10000, backupCount=3)
  logger = Logger('app.log', level='DEBUG', handler=handler)

  def my_function():
      logger.info('my_function was called')
      try:
          result = 10 / 0
      except ZeroDivisionError as e:
          logger.exception('An error occurred in my_function:', e)

  if __name__ == '__main__':
      logger.info('Starting the application...')
      my_function()
