Logging made simple.

logpie

Logging made simple.

This is a simple logging module with thread & file locking abilities.

---

Installation:

python -m pip install [--upgrade] logpie

---

Usage:

# your `main.py` module

from os.path import dirname, realpath, join
from sys import modules
from types import ModuleType

from cfgpie import get_config, CfgParser
from logpie import get_logger, Logger

# **************************** config constants: **************************** #

# main module
MODULE: ModuleType = modules.get("__main__")

# root directory
ROOT: str = dirname(realpath(MODULE.__file__))

# default config file path:
CONFIG: str = join(ROOT, "config", "cfgpie.ini")

# backup config params:
BACKUP: dict = {
    "LOGGER": {
        "basename": "logpie",  # if handler is `file`
        "folder": r"${DEFAULT:directory}\logs",
        "handlers": ["file"],  # or `console` or both (always as list)
        "level": 0,  # logs all messages above this level
    }
}

# NOTE: The constants above serve the usage example,
#       and you can use whatever suits you best.

# ********************** get `ConfigParser` instance: *********************** #

cfg: CfgParser = get_config(name="my_config")
cfg.set_defaults(directory=ROOT)
cfg.open(file_path=CONFIG, encoding="UTF-8", fallback=BACKUP)

# ************************* get `Logger` instance: ************************** #

# we can pass a config instance:
log: Logger = get_logger(name="my_logger", config=cfg)

or

# it will look for a config instance named `my_config`:
log: Logger = get_logger(name="my_logger", config="my_config")

or

# it will create and use its own config instance:
log: Logger = get_logger(name="my_logger", level="debug", handlers="file", basename="logpie")


if __name__ == '__main__':
    log.debug("Testing debug messages...")
    log.info("Testing info messages...")
    log.warning("Testing warning messages...")
    log.error("Testing error messages...")
    log.critical("Testing critical messages...")

By default, logging level is set to NOTSET (0) and it logs all messages.

The log file is prefixed with a date and will have an index number attached before the extension (ex: 2022-08-01_logpie.1.log). When it reaches 1 Mb the file handler will switch to another file by incrementing its index with 1.

The folder tree is by default structured as follows:

.
└───logs
    └───year (ex: 2022)
        └───month (ex: january)
            ├───2022-08-01_logpie.1.log
            ├───2022-08-01_logpie.2.log
            └───2022-08-01_logpie.3.log

When the current month changes, a new folder is created and the previous one is archived.
