**Documentation**: [watchfiles.helpmanual.io](https://watchfiles.helpmanual.io)
**Source Code**: [github.com/samuelcolvin/watchfiles](https://github.com/samuelcolvin/watchfiles)
---
Underlying file system notifications are handled by the [Notify](https://github.com/notify-rs/notify) rust library.
This package was previously named "watchgod",
see [the migration guide](https://watchfiles.helpmanual.io/migrating/) for more information.
## Installation
**watchfiles** requires Python 3.9 - 3.14.
```bash
pip install watchfiles
```
Binaries are available for most architectures on Linux, MacOS and Windows ([learn more](https://watchfiles.helpmanual.io/#installation)).
Otherwise, you can install from source which requires Rust stable to be installed.
## Usage
Here are some examples of what **watchfiles** can do:
### `watch` Usage
```py
from watchfiles import watch
for changes in watch('./path/to/dir'):
print(changes)
```
See [`watch` docs](https://watchfiles.helpmanual.io/api/watch/#watchfiles.watch) for more details.
### `awatch` Usage
```py
import asyncio
from watchfiles import awatch
async def main():
async for changes in awatch('/path/to/dir'):
print(changes)
asyncio.run(main())
```
See [`awatch` docs](https://watchfiles.helpmanual.io/api/watch/#watchfiles.awatch) for more details.
### `run_process` Usage
```py
from watchfiles import run_process
def foobar(a, b, c):
...
if __name__ == '__main__':
run_process('./path/to/dir', target=foobar, args=(1, 2, 3))
```
See [`run_process` docs](https://watchfiles.helpmanual.io/api/run_process/#watchfiles.run_process) for more details.
### `arun_process` Usage
```py
import asyncio
from watchfiles import arun_process
def foobar(a, b, c):
...
async def main():
await arun_process('./path/to/dir', target=foobar, args=(1, 2, 3))
if __name__ == '__main__':
asyncio.run(main())
```
See [`arun_process` docs](https://watchfiles.helpmanual.io/api/run_process/#watchfiles.arun_process) for more details.
## CLI
**watchfiles** also comes with a CLI for running and reloading code. To run `some command` when files in `src` change:
```
watchfiles "some command" src
```
For more information, see [the CLI docs](https://watchfiles.helpmanual.io/cli/).
Or run
```bash
watchfiles --help
```
