A simple program that uses watchers.py to monitor specified directory in 2 seconds interval. It prints the message on a change in a file system.
from watchers import SimpleWatcher def foo(): print('Something has changed in directory!') x = SimpleWatcher(2, 'path/to/dir', foo) x.start()
Why polling? WHY?!
Because it works everywhere and has no other dependencies than pure Python.

pip install watchers.py
