# Import required modules
from subprocess import Popen, PIPE  # For starting the main.py script
import sys  # For getting the path to the current Python interpreter
from watchdog.observers import Observer  # For monitoring file system events
from watchdog.events import FileSystemEventHandler  # For handling file system events

# Define a custom event handler for file system events
class MyHandler(FileSystemEventHandler):
    # Define a function to be called when any file system event occurs
    def on_any_event(self, event):
        # Print a message indicating which file was changed
        print(f"Restarting script due to changes in {event.src_path}")
        # Start the main.py script using the current Python interpreter
        Popen([sys.executable, "main.py"], stdout=PIPE, stderr=PIPE)

# Create an observer object to monitor file system events
observer = Observer()
# Schedule the custom event handler to be called for all file system events in current directory
observer.schedule(MyHandler(), ".", recursive=True)
# Start the observer
observer.start()

# Print a message indicating that the script is running
print("Script is running. Press Ctrl+C to stop.")

# Wait for the observer to stop (e.g. when Ctrl+C is pressed)
try:
    while True:
        pass
except KeyboardInterrupt:
    observer.stop()

# Join the observer thread
observer.join()
