TARDIS Logger Widget Demo

This notebook demonstrates how to use the TARDIS logging widget in a Jupyter environment.

import sys
import os
sys.path.append(os.path.dirname(os.path.abspath('')))  # Add parent directory to path

import logging
import time
from logger import logging_state

# Initialize the logging widget - this will display the widget in the notebook
widget = logging_state(log_level="DEBUG", display_logging_widget=True)

# Get the tardis logger
logger = logging.getLogger("tardis")

Basic Logging Examples

Let’s try different log levels. You’ll see the messages appear in different tabs of the widget above.

# Debug level message
logger.debug("🔍 This is a debug message - useful for detailed debugging information"*10000000)

# Info level message
logger.info("ℹ️ This is an info message - general information about program execution")

# Warning level message
logger.warning("⚠️ This is a warning message - something might be wrong!")

# Error level message
logger.error("❌ This is an error message - something has definitely gone wrong!")

Structured Logging Example

You can include variables and formatted strings in your logs:

batch_number = 42
processed_items = 100

logger.info("📊 Processing batch %d with %d items", batch_number, processed_items)
logger.debug("🔢 Current processing rate: %.2f items/second", processed_items/2.5)

Exception Logging Example

The logger can capture and display exception information:

try:
    result = 1 / 0
except Exception as e:
    logger.error("💥 An error occurred during calculation", exc_info=True)

Changing Log Levels

You can change the log level at any time:

# Switch to INFO level - debug messages will no longer appear
widget = logging_state(log_level="INFO", display_logging_widget=True)

logger.debug("🔍 This debug message won't appear")
logger.info("ℹ️ But this info message will!")
