Example

Here's an example logger using fifo_folder to limit the resources used by log files:

import os

from fifo_folder import FIFOFolder

LOG_DIR_PATH = "/path/to/your/log/folder/"

log_manager = FIFOFolder(
    LOG_DIR_PATH,  # path to the folder to manage
    count_limit=100,  # keep at most 100 files
    total_size_limit=(1 << 30),  # keep sum of file sizes no greater than 1GB
)


def log(file_name: str, text: str) -> None:

    # create a new log file
    file_path = os.path.join(LOG_DIR_PATH, file_name)
    with open(file_path, "w") as file:
        file.write(text)

    log_manager.load_items()  # load current files
    removed_items = log_manager.manage()  # removed extra files
    if len(removed_items):  # display removed files
        print(
            "removed log files:",
            [os.path.basename(item.data.path) for item in removed_items]
        )
