"""Utility helpers to handle progress bars in `huggingface_hub`.

Example:
    1. Use `huggingface_hub.utils.tqdm` as you would use `tqdm.tqdm` or `tqdm.auto.tqdm`.
    2. To disable progress bars, either use `disable_progress_bars()` helper or set the
       environment variable `HF_HUB_DISABLE_PROGRESS_BARS` to 1.
    3. To re-enable progress bars, use `enable_progress_bars()`.
    4. To check whether progress bars are disabled, use `are_progress_bars_disabled()`.

NOTE: Environment variable `HF_HUB_DISABLE_PROGRESS_BARS` has the priority.

Example:
    ```py
    from huggingface_hub.utils import (
        are_progress_bars_disabled,
        disable_progress_bars,
        enable_progress_bars,
        tqdm,
    )

    # Disable progress bars globally
    disable_progress_bars()

    # Use as normal `tqdm`
    for _ in tqdm(range(5)):
       do_something()

    # Still not showing progress bars, as `disable=False` is overwritten to `True`.
    for _ in tqdm(range(5), disable=False):
       do_something()

    are_progress_bars_disabled() # True

    # Re-enable progress bars globally
    enable_progress_bars()

    # Progress bar will be shown !
    for _ in tqdm(range(5)):
       do_something()
    ```

    Open a file as binary and wrap the `read` method to display a progress bar when it's streamed.

    First implemented in `transformers` in 2019 but removed when switched to git-lfs. Used in `huggingface_hub` to show
    progress bar when uploading an LFS file to the Hub. See github.com/huggingface/transformers/pull/2078#discussion_r354739608
    for implementation details.

    Note: currently implementation handles only files stored on disk as it is the most common use case. Could be
          extended to stream any `BinaryIO` object but we might have to debug some corner cases.

    Example:
    ```py
    >>> with tqdm_stream_file("config.json") as f:
    >>>     requests.put(url, data=f)
    config.json: 100%|█████████████████████████| 8.19k/8.19k [00:02<00:00, 3.72kB/s]
