Introduction to Flip Logger

Flip Logger is a comprehensive logging utility that provides a wide range of APIs for logging in your applications. It offers simple and effective logging methods that can enhance debugging and tracking events in your applications.

Basic Usage

Using Flip Logger is straightforward. You can quickly get started with a few lines of code:

  import flip_logger as logger

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

Advanced Logging

Flip Logger also supports advanced logging techniques, such as logging exceptions, custom log levels, and writing logs to files:

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

  # Custom log level
  logger.log(25, "A custom log level message")

  # Logging to a file
  logger.setup_file_logging("application.log")
  logger.info("Log this message to a file")

Logging in Web Applications

Flip Logger can be used seamlessly in web applications. Below is an example using Flask:

  from flask import Flask
  import flip_logger as logger

  app = Flask(__name__)

  @app.route("/")
  def home():
      logger.info("Home page was accessed")
      return "Welcome to the Home Page"

  @app.route("/error")
  def error_page():
      try:
          1 / 0
      except ZeroDivisionError as e:
          logger.exception("Error page triggered an exception: ", e)
      return "This is an error page"

  if __name__ == "__main__":
      logger.setup_file_logging("app.log")
      app.run(debug=True)

Customizing Log Output

Flip Logger allows you to customize log formatting to suit your needs:

  custom_format = "%(levelname)s: %(asctime)s - %(message)s"
  logger.setup_custom_logging(format=custom_format)

  logger.info("This message uses a custom format")

Asynchronous Logging

In high-performance applications, you may need non-blocking logging:

  from flip_logger.async_logging import AsyncLogger

  async_logger = AsyncLogger("async.log")

  async_logger.info("Logging asynchronously")

  async_logger.close()  # ensure all logs are flushed and file handlers are properly closed

With these powerful features, Flip Logger can greatly enhance your application’s logging capabilities.
