Helpful classes, functions, & utilities for the stdlib logging module. No external dependencies.

Why?

I wanted to learn the stdlib logging module, and found I liked configuring my logger(s) with logging.config.dictConfig(). However, I did not want to have to continually check reference pages, copy/paste code, and do all the logging setup by hand each time.

red-log does not import any 3rd party modules, only Python's stdlib modules are used. This package does not necessarily aim to simplify configuring logging, but the config classes help by exposing configuration options for the logging module's formatters, handlers, and loggers.

Logger Configuration

With dictConfig()

Base config dict:

{
    "version": 1,
    "disable_existing_loggers": False,
    "propagate": True,
    "root": {},
    "formatters": {},
    "handlers": {},
    "loggers": {}
}

from logging.config import dictConfig

logging_configdict: dict = {
    "version": 1,
    "disable_existing_loggers": false,
    "propagate": true,
    "root": {
        "": {
            "handlers": [
                "console"
            ],
            "level": "NOTSET"
        }
    },
    "formatters": {
        "default": {
            "format": "[%(asctime)s] [%(levelname)s] > [%(filename)s:%(lineno)d] [%(funcName)s]: %(message)s",
            "datefmt": "%Y-%m-%d %H:%M:%S"
        }
    },
    "handlers": {
        "console": {
            "class": "logging.StreamHandler",
            "formatter": "default",
            "level": "DEBUG",
            "stream": "ext://sys.stdout"
        }
    },
    "loggers": {
        "": {
            "handlers": [
                "console"
            ],
            "level": "NOTSET"
        }
    }
}

dictConfig(logging_configdict)
log = logging.getLogger(__name__)

log.info("Logger configured")
