advlog v0.1.0 - the very first implement

advlog-core

A powerful, feature-rich logging library for Python with beautiful terminal output, flexible configuration, and extensive plugin support.

✨ Features

• 🎨 Rich Console Output - Beautiful colored terminal logging with Rich library
• 📊 Progress Tracking - Integrated progress bars with automatic management
• 🔧 Flexible Configuration - Easy-to-use configuration system based on dataclasses
• 📁 Smart File Management - Log rotation, intelligent naming, and multiple file strategies
• 🎯 Multi-Module Coordination - LoggerManager for unified logging across modules
• 🔍 Source Information - Automatic display of log origin (file, line, function)
• 📐 Aligned Formatting - Precise control over field width and alignment
• 🌍 Environment Adaptive - Automatic detection and adaptation to different environments
• 🚀 ML/AI Ready - Built-in support for machine learning training logs

📦 Installation

Install from PyPI:

pip install advlog-core

Install with all optional features:

pip install "advlog-core[all]"

Note: The PyPI package name is advlog-core, but when importing in Python, use import advlog.

🚀 Quick Start

Basic Usage

from advlog import get_logger

# Create a logger for the current module
log = get_logger(__name__)

# Use the logger
log.info("Application started")
log.warning("High memory usage detected")
log.error("Database connection failed")

Initialize Logging System

from advlog import initialize, get_logger, get_progress

# Initialize the logging system
initialize(
    output_dir="./logs",
    session_name="myapp",
    log_level="DEBUG",
    show_location=True
)

# Get logger and progress tracker
log = get_logger(__name__)
progress = get_progress()

# Use in a workflow
with progress:
    task = progress.add_task("Processing", total=100)
    for i in range(100):
        # Do work
        progress.update(task, advance=1)

🏗️ Real-World Example

For a complete multi-module application example, see examples/real_world_demo/. This demonstrates:

1. Global logging initialization - Set up logging once at application start
2. Cross-module logging - Share loggers across multiple Python files
3. Progress tracking - Track long-running workflows
4. Error handling - Comprehensive error logging
5. File management - Organized log file structure

Run it:

python -m examples.real_world_demo.main

📋 Advanced Usage

Multiple Loggers with Manager

from advlog import LoggerManager, get_logger

# Create a logger manager for coordinated logging
manager = LoggerManager(shared_console=True)

# Register loggers for different modules
api_logger = manager.register_logger("api")
db_logger = manager.register_logger("database", log_level="DEBUG")
auth_logger = manager.register_logger("auth")

# Use them
api_logger.info("API server started")
db_logger.debug("Executing query")
auth_logger.warning("Invalid login attempt")

Smart File Naming

from advlog import LogNamingStrategy

# Timestamp-based naming
log_file = LogNamingStrategy.timestamped("app", suffix="production")
# Result: logs/2026-01-05/20260105_143022_app_production.log

# Daily directory structure
log_file = LogNamingStrategy.daily("myapp", suffix="errors")
# Result: logs/2026-01-05/myapp_errors.log

# Incremental naming (avoids conflicts)
log_file = LogNamingStrategy.incremental("backup", suffix="data")
# Result: logs/backup_data.log (or backup_data_1.log if exists)

Progress Tracking

from advlog import ProgressTracker

with ProgressTracker() as progress:
    # Add multiple tasks
    download_task = progress.add_task("Downloading files", total=100)
    process_task = progress.add_task("Processing data", total=50)

    # Update progress
    for i in range(100):
        # Download file
        progress.update(download_task, advance=1)

    for i in range(50):
        # Process data
        progress.update(process_task, advance=1)

ML Training Logger

from advlog import AdvancedLogger, TrainingLogger

# Create logger
logger = AdvancedLogger().get_logger()

# Create training logger
trainer = TrainingLogger(logger)

# Log training step
trainer.log_train_step(
    epoch=1,
    total_epochs=10,
    batch=100,
    total_batches=1000,
    loss_dict={"loss": 0.5, "accuracy": 0.85},
    learning_rate=0.001,
    time_elapsed=45.2
)

🛠️ Dependencies

This project is built to be lightweight. While the core functionality requires minimal setup, certain features are enabled only when optional dependencies are installed.

Required

These are necessary for the basic operation of advlog-core:

• Rich (MIT License): Used for beautiful terminal formatting and logging.

Optional

Install these based on your specific use case:

• OmegaConf (BSD-3-Clause): Required for advanced configuration file parsing.
• torchinfo (MIT License): Required for model structure visualization.
• Accelerate (Apache-2.0): Required for distributed training and multi-GPU logging support.

Installation

You can install the core package with:

pip install advlog-core

To include all optional features, you can use the extra tag:

pip install "advlog-core[all]"

Or install specific optional dependencies:

pip install "advlog-core[config]"      # For OmegaConf support
pip install "advlog-core[torch]"       # For torchinfo support
pip install "advlog-core[distributed]" # For Accelerate support
