Internally, `run_process` uses [`watch`][watchfiles.watch] with `raise_interrupt=False` so the function exits cleanly upon `Ctrl+C`. Args: *paths: matches the same argument of [`watch`][watchfiles.watch] target: function or command to run args: arguments to pass to `target`, only used if `target` is a function kwargs: keyword arguments to pass to `target`, only used if `target` is a function target_type: type of target. Can be `'function'`, `'command'`, or `'auto'` in which case [`detect_target_type`][watchfiles.run.detect_target_type] is used to determine the type. callback: function to call on each reload, the function should accept a set of changes as the sole argument watch_filter: matches the same argument of [`watch`][watchfiles.watch] grace_period: number of seconds after the process is started before watching for changes debounce: matches the same argument of [`watch`][watchfiles.watch] step: matches the same argument of [`watch`][watchfiles.watch] debug: matches the same argument of [`watch`][watchfiles.watch] sigint_timeout: the number of seconds to wait after sending sigint before sending sigkill sigkill_timeout: the number of seconds to wait after sending sigkill before raising an exception recursive: matches the same argument of [`watch`][watchfiles.watch] Returns: number of times the function was reloaded. ```py title="Example of run_process running a function" from watchfiles import run_process def callback(changes): print('changes detected:', changes) def foobar(a, b): print('foobar called with:', a, b) if __name__ == '__main__': run_process('./path/to/dir', target=foobar, args=(1, 2), callback=callback) ``` As well as using a `callback` function, changes can be accessed from within the target function, using the `WATCHFILES_CHANGES` environment variable. ```py title="Example of run_process accessing changes" from watchfiles import run_process def foobar(a, b, c): # changes will be an empty list "[]" the first time the function is called changes = os.getenv('WATCHFILES_CHANGES') changes = json.loads(changes) print('foobar called due to changes:', changes) if __name__ == '__main__': run_process('./path/to/dir', target=foobar, args=(1, 2, 3)) ``` Again with the target as `command`, `WATCHFILES_CHANGES` can be used to access changes. ```bash title="example.sh" echo "changers: ${WATCHFILES_CHANGES}" ``` ```py title="Example of run_process running a command" from watchfiles import run_process if __name__ == '__main__': run_process('.', target='./example.sh') ``` rrunning "%s" as %sr3sleeping for %s seconds before watching for changesF)rr!r"r#raise_interruptr&r')r$r%r )rloggerr# catch_sigterm start_processr rstop)r)rrrrrr r!r"r#r$r%r&r'r(processreloadschangess K/var/www/reloj-farallon/venv/lib/python3.13/site-packages/watchfiles/run.pyrrs@f(0  LL%v;OF>GG JLY l %!%=  G  *'* LLL X#FwOG qLG     N  s )A CC) rrrrrr r!r"r#r&r'c # SSKn US:Xa [U5n[RSX5 [ 5 [ R R[XX5IShvN nSnU(a4[RSU5 [ R"U5IShvN [U UUUU U U S.6ShvN nUb(U"U5nU RU5(a UIShvN [ R RUR5IShvN [ R R[XXU5IShvN nUS- nMNNNNpNAN [ R RUR5IShvN U$7f)a Async equivalent of [`run_process`][watchfiles.run_process], all arguments match those of `run_process` except `callback` which can be a coroutine. Starting and stopping the process and watching for changes is done in a separate thread. As with `run_process`, internally `arun_process` uses [`awatch`][watchfiles.awatch], however `KeyboardInterrupt` cannot be caught and suppressed in `awatch` so these errors need to be caught separately, see below. ```py title="Example of arun_process usage" import asyncio from watchfiles import arun_process async def callback(changes): await asyncio.sleep(0.1) print('changes detected:', changes) def foobar(a, b): print('foobar called with:', a, b) async def main(): await arun_process('.', target=foobar, args=(1, 2), callback=callback) if __name__ == '__main__': try: asyncio.run(main()) except KeyboardInterrupt: print('stopped via KeyboardInterrupt') ``` rNrr,r-)rr!r"r#r&r'r ) inspectrr/r#r0anyio to_threadrun_syncr1r r isawaitabler2)r)rrrrrr r!r"r#r&r'r(r8r3r4r5rs r6rrsKZf(0  LL%v;OOO,,]FQU^^GG JLYkk,''' ! !9g  !A""1%%oo&&w||44400UYcjkk1 /_ (4k" // " "7<< 000 NsAF  E !47D"GFG''w&'Q  6 NNJ K&#&&U(UU&v& "":. 7 ##/&LsD# c[U[5(dgURS5(ag[R"SU5(agg)a& Used by [`run_process`][watchfiles.run_process], [`arun_process`][watchfiles.arun_process] and indirectly the CLI to determine the target type with `target_type` is `auto`. Detects the target type - either `function` or `command`. This method is only called with `target_type='auto'`. The following logic is employed: * If `target` is not a string, it is assumed to be a function * If `target` ends with `.py` or `.sh`, it is assumed to be a command * Otherwise, the target is assumed to be a function if it matches the regex `[a-zA-Z0-9_]+(\.[a-zA-Z0-9_]+)+` If this logic does not work for you, specify the target type explicitly using the `target_type` function argument or `--target-type` command line argument.
