📑 quick start

from dlogger import logger

logger.info("hello, world!")
logger.error("something went wrong")

with configuration:

from dlogger import logger

logger.configure(
    level="INFO",
    log_file="app.log",
    rotation="10MB",
    retention="7 days",
    compression=True
)

logger.debug("this won't be shown")
logger.info("but this will")

🧩 features

• 🎨 TrueColor output — HEX/RGB support powered by dcolor
• 🚀 high performance — use of buffers and call context caching
• 🧵 thread safety — stability in multithreaded applications thanks to locks
• 💾 write guarantee — automatic buffer reset upon correct program termination
• 📁 smart rotation — by size (10MB, 1GB) or time (1 day, 12 hours)
• 🗑️ auto cleanup — scheduled deletion of old files (retention="30 days")
• 📦 compression — automatic archiving of old logs to .gz
• 🛠️ minimal dependencies — only dcolor
• ✅ reliability — protection from memory leaks, data loss and deadlocks
• 🏗️ modular architecture — extensible via handlers, formatters and filters

📖 usage

log levels

logger.configure(level="INFO")  # DEBUG, INFO, WARNING, ERROR, CRITICAL

size-based rotation

logger.configure(
    log_file="app.log",
    rotation="10MB"  # or "500KB", "1GB"
)

once the file reaches 10MB → app.log.20260216_143022

time-based rotation

logger.configure(
    log_file="app.log",
    rotation="1 day"  # or "12 hours", "1 week"
)

log retention

logger.configure(
    log_file="app.log",
    retention="7 days"  # or "2 weeks", "1 month"
)

logs older than 7 days will be deleted automatically

compression

logger.configure(
    log_file="app.log",
    rotation="10MB",
    compression=True  # old logs → .gz
)

full configuration

logger.configure(
    level="INFO",              # minimum log level
    log_file="logs/app.log",   # path to log file
    show_path=True,            # show module:function:
    rotation="10MB",           # size-based rotation
    retention="7 days",        # keep logs for 7 days
    compression=True           # compress old logs
    time_format="%H:%M:%S"     # time format - 14:30:22
)

💡 examples

simple logging

from dlogger import logger

logger.info("server started on port 8000")
logger.warning("memory usage at 80%")
logger.error("failed to connect to database")

with file

from dlogger import logger

logger.configure(
    level="DEBUG",
    log_file="app.log"
)

logger.debug("starting request processing")
logger.info("request processed successfully")

for production

from dlogger import logger

logger.configure(
    level="INFO",
    log_file="logs/production.log",
    rotation="50MB",
    retention="30 days",
    compression=True
    time_format="%Y-%m-%d %H:%M:%S"
)

logger.info("application started")
logger.error("critical error in payments module")

extensibility (handlers, formatters, filters)

from dlogger import dLogger, ConsoleHandler, FileHandler, LevelFilter

# create your own logger
my_logger = dLogger()

# add handlers
my_logger.add_handler(ConsoleHandler(level="DEBUG"))
my_logger.add_handler(FileHandler("app.log", rotation="10MB"))

# or use the default logger and add/remove handlers
from dlogger import logger
logger.remove_handler(logger.handlers[0])  # remove console handler
logger.add_handler(FileHandler("debug.log", level="DEBUG"))

multiple loggers

from dlogger import dLogger

# independent loggers for different modules
app_logger = dLogger().configure(level="INFO", log_file="app.log")
db_logger = dLogger().configure(level="DEBUG", log_file="db.log")

app_logger.info("application started")
db_logger.debug("database query executed")
