nba-log 0.1.0

A ported Go logger with ANSI styling and file rotation

nba-log

A lightweight, synchronized Python logger with ANSI color support and automatic file rotation. Ported from a Golang logging utility to provide a clean, "tagged" logging experience for console and file-based output.

Features

• 🎨 ANSI Styling: Full support for foreground, background, and font styles (Bold, Italic, etc.).
• 🏷️ Tagged Logs: Every log entry includes a fixed-width tag (7 characters) for easy visual alignment.
• 📂 File Rotation: Background thread support to rotate logs at a specific time (e.g., daily at midnight).
• 🚀 Synchronous & Simple: Built for reliability and ease of use in Python scripts and applications.

Installation

You can install the library via pip:

pip install nba-log

Quick Start

from nba_log import Logger

# Initialize with a tag and debug mode enabled
log = Logger("GPIO", debug_mode=True)

# Apply standard colors (Info: White, Warn: Yellow, Error: Red, etc.)
log.set_default_style()

log.info("System initialized")
log.debug("Checking sensors...") # Only visible if debug_mode=True
log.error("Failed to reach server")

Advanced Usage

File Logging & Auto-Rotation

Enable persistent logging to a directory. The logger will automatically append the date to the filename.

import time
from nba_log import Logger

# 1. Setup Logger
log = Logger("SERVER", debug_mode=True)
log.set_default_style()

# 2. Enable file writing (Directory Path, File Prefix)
log.set_write_files_enable("./logs", "api_service")

# 3. Schedule rotation at 00:00 (Midnight)
# The logger handles the timing in the background
log.change_file_routine(0, 0)

log.info("Continuous logging started. Press Ctrl+C to stop.")

try:
    # 4. Infinite loop to print every 1 minute
    while True:
        log.info("Heartbeat: Service is healthy")

        # Wait for 5 seconds
        time.sleep(5)
        
except KeyboardInterrupt:
    log.warn("Logging stopped by user.")

Custom Styling

You can override default styles using the provided constants. Styles are lists of ANSI codes.

from nba_log import Logger, StyleFgYellow, StyleFontBold, StyleBgRed

log = Logger("APP", True)

# Custom style for warnings: Bold and Yellow text
log.warn_style = [StyleFontBold, StyleFgYellow]

# Custom style for fatal errors: Bold black text on a Red background
log.fatal_style = [StyleFontBold, StyleBgRed]

log.warn("This is a custom warning style!")
