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

Example:
    1. Use `datasets.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_DATASETS_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_DATASETS_DISABLE_PROGRESS_BARS` has the priority.

Example:
    ```py
    from datasets.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()
    ```
