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: ${WATCHFILES_CHANGES}" ``` ```py title="Example of run_process running a command" from watchfiles import run_process if __name__ == '__main__': run_process('.', target='./example.sh') ``` rrunning "%s" as %sr3sleeping for %s seconds before watching for changesF)r%r'r(r)raise_interruptr,r-)r*r+r)rloggerr) catch_sigterm start_processrrstop)r/r!r"r#r$r%r&r'r(r)r*r+r,r-r.processreloadschangess O/var/www/html/kelly-backend/venv/lib/python3.12/site-packages/watchfiles/run.pyrrs@f(0  LL%v{;OFKv>GG JLY l %!%=  G  *'* LLL X#FKvwOG qLG     N  s &A CC) r!r"r#r$r%r&r'r(r)r,r-c Kddl} |dk(r t|}tjd||t t j jt||||d{}d}|r3tjd|t j|d{t| |||| | | d23d{}|#||}| j|r |d{t j j|jd{t j jt|||||d{}|dz }7777q7B76t j j|jd{7|Sw)a  Async equivalent of [`run_process`][watchfiles.run_process], all arguments match those of `run_process` except `callback` which can be a coroutine. Starting and stopping the process and watching for changes is done in a separate thread. As with `run_process`, internally `arun_process` uses [`awatch`][watchfiles.awatch], however `KeyboardInterrupt` cannot be caught and suppressed in `awatch` so these errors need to be caught separately, see below. ```py title="Example of arun_process usage" import asyncio from watchfiles import arun_process async def callback(changes): await asyncio.sleep(0.1) print('changes detected:', changes) def foobar(a, b): print('foobar called with:', a, b) async def main(): await arun_process('.', target=foobar, args=(1, 2), callback=callback) if __name__ == '__main__': try: asyncio.run(main()) except KeyboardInterrupt: print('stopped via KeyboardInterrupt') ``` rNrr2r3)r%r'r(r)r,r-r) inspectrr5r)r6anyio to_threadrun_syncr7rr isawaitabler8)r/r!r"r#r$r%r&r'r(r)r,r-r.r>r9r:r;rs r<rrs[Zf(0  LL%v{;OOO,,]FKQUW]^^GG JLYkk,''' ! !9g  !A""1%oo&&w||44400 UY[acjkk1 /_ (4k" // " "7<< 000 NsA F"E#6FEF.E2E3E6!FE 0FE  /F8E 9 FFE F F F-F<E?=Fspawncmdcddl}|jjjdk7}t j ||S)Nrwindows)posix)platformunamesystemlowershlexsplit)rErIrHs r< split_cmdrOs6 NN  # # ) ) +y 8E ;;s% ((zLiteral['function', 'command']r;CombinedProcessc2|d}n8tj|Dcgc]\}}|j|gc}}}|tjd<|dk(rb|xsi}t |t r|t||f}t}i}n|}tj|||} | jt#| S|s|rtjdt |t sJdt|} tj | } t#| Scc}}w)Nz[]WATCHFILES_CHANGESfunction)r/r!r"z-ignoring args and kwargs for "command" targetz+target must be a string to run as a command)jsondumpsraw_strosenviron isinstancestr get_tty_path run_function spawn_contextProcessstartr5warningrO subprocessPopenrQ) r/r#r!r"r;changes_env_varcptarget_r9 popen_argss r<r7r7s**7%K741aqyy{A&67%KL'6BJJ#$j 2 fc "<>47D"GFG''wT&'Q  7 ## 6 NNJ K&#&U(UU&v& "":. 7 ##/&LsD cxt|tsy|jdrytjd|ryy)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.
