The paths watched can be directories or files, directories are watched recursively - changes in subdirectories are also detected. #### Force polling Notify will fall back to file polling if it can't use file system notifications, but we also force Notify to use polling if the `force_polling` argument is `True`; if `force_polling` is unset (or `None`), we enable force polling thus: * if the `WATCHFILES_FORCE_POLLING` environment variable exists and is not empty: * if the value is `false`, `disable` or `disabled`, force polling is disabled * otherwise, force polling is enabled * otherwise, we enable force polling only if we detect we're running on WSL (Windows Subsystem for Linux) Args: *paths: filesystem paths to watch. watch_filter: callable used to filter out changes which are not important, you can either use a raw callable or a [`BaseFilter`][watchfiles.BaseFilter] instance, defaults to an instance of [`DefaultFilter`][watchfiles.DefaultFilter]. To keep all changes, use `None`. debounce: maximum time in milliseconds to group changes over before yielding them. step: time to wait for new changes in milliseconds, if no changes are detected in this time, and at least one change has been detected, the changes are yielded. stop_event: event to stop watching, if this is set, the generator will stop iteration, this can be anything with an `is_set()` method which returns a bool, e.g. `threading.Event()`. rust_timeout: maximum time in milliseconds to wait in the rust code for changes, `0` means no timeout. yield_on_timeout: if `True`, the generator will yield upon timeout in rust even if no changes are detected. debug: whether to print information about all filesystem changes in rust to stdout, if `None` will use the `WATCHFILES_DEBUG` environment variable. raise_interrupt: whether to re-raise `KeyboardInterrupt`s, or suppress the error and just stop iterating. force_polling: See [Force polling](#force-polling) above. poll_delay_ms: delay between polling for changes, only used if `force_polling=True`. recursive: if `True`, watch for changes in sub-directories recursively, otherwise watch only for changes in the top-level directory, default is `True`. ignore_permission_denied: if `True`, will ignore permission denied errors, otherwise will raise them by default. Setting the `WATCHFILES_IGNORE_PERMISSION_DENIED` environment variable will set this value too. Yields: The generator yields sets of [`FileChange`][watchfiles.main.FileChange]s. ```py title="Example of watch usage" from watchfiles import watch for changes in watch('./first/dir', './second/dir', raise_interrupt=False): print(changes) ``` cSg|]}t|qSrr$.0prrr xzwatch..Ttimeoutrust notify timeout, continuingsignalz(KeyboardInterrupt caught, stopping watchNstop(all changes filtered out, raw_changes=%s) _default_force_polling!_default_ignore_permission_denied_default_debugr rsetloggerr1KeyboardInterruptwarning _prep_changes _log_changes)r+r,r-r.r/r0r1r2r3r4r5r6r7watcher raw_changeschangesrrrr4s<@     rAnyEventc  Gs|dur tdt|durt} n|} t|}t| } t|}tdd| D||| | | }t |}t } t 4IdH/}ztj |j|||| IdH}Wn|tfya| w|jWdIdHn 1IdHswwY|dkr|rtVn0tdn*|dkr WddS|d krtd t||}|rt||Vntd |q:1swYdS) a Asynchronous equivalent of [`watch`][watchfiles.watch] using threads to wait for changes. Arguments match those of [`watch`][watchfiles.watch] except `stop_event`. All async methods use [anyio](https://anyio.readthedocs.io/en/latest/) to run the event loop. Unlike [`watch`][watchfiles.watch] `KeyboardInterrupt` cannot be suppressed by `awatch` so they need to be caught where `asyncio.run` or equivalent is called. Args: *paths: filesystem paths to watch. watch_filter: matches the same argument of [`watch`][watchfiles.watch]. debounce: matches the same argument of [`watch`][watchfiles.watch]. step: matches the same argument of [`watch`][watchfiles.watch]. stop_event: `anyio.Event` which can be used to stop iteration, see example below. rust_timeout: matches the same argument of [`watch`][watchfiles.watch], except that `None` means use `1_000` on Windows and `5_000` on other platforms thus helping with exiting on `Ctrl+C` on Windows, see [#110](https://github.com/samuelcolvin/watchfiles/issues/110). yield_on_timeout: matches the same argument of [`watch`][watchfiles.watch]. debug: matches the same argument of [`watch`][watchfiles.watch]. raise_interrupt: This is deprecated, `KeyboardInterrupt` will cause this coroutine to be cancelled and then be raised by the top level `asyncio.run` call or equivalent, and should be caught there. See [#136](https://github.com/samuelcolvin/watchfiles/issues/136) force_polling: if true, always use polling instead of file system notifications, default is `None` where `force_polling` is set to `True` if the `WATCHFILES_FORCE_POLLING` environment variable exists. poll_delay_ms: delay between polling for changes, only used if `force_polling=True`. recursive: if `True`, watch for changes in sub-directories recursively, otherwise watch only for changes in the top-level directory, default is `True`. ignore_permission_denied: if `True`, will ignore permission denied errors, otherwise will raise them by default. Setting the `WATCHFILES_IGNORE_PERMISSION_DENIED` environment variable will set this value too. Yields: The generator yields sets of [`FileChange`][watchfiles.main.FileChange]s. ```py title="Example of awatch usage" import asyncio from watchfiles import awatch async def main(): async for changes in awatch('./first/dir', './second/dir'): print(changes) if __name__ == '__main__': try: asyncio.run(main()) except KeyboardInterrupt: print('stopped via KeyboardInterrupt') ``` ```py title="Example of awatch usage with a stop event" import asyncio from watchfiles import awatch async def main(): stop_event = asyncio.Event() async def stop_soon(): await asyncio.sleep(3) stop_event.set() stop_soon_task = asyncio.create_task(stop_soon()) async for changes in awatch('/path/to/dir', stop_event=stop_event): print(changes) # cleanup by awaiting the (now complete) stop_soon_task await stop_soon_task asyncio.run(main()) ``` Nzraise_interrupt is deprecated, KeyboardInterrupt will cause this coroutine to be cancelled and then be raised by the top level asyncio.run call or equivalent, and should be caught there.
