How to get Bottle to restart on file change?

To make a Bottle application automatically restart when a file changes, you can use a development server like bottle-devserver or a more general tool like watchdog. Here are two different approaches you can take:

1. Using bottle-devserver:

bottle-devserver is a development server for Bottle that includes an automatic reloading feature. You can install it via pip:

pip install bottle-devserver

Here's how you can use it:

from bottle_devserver import DevServer from bottle import route, run @route('/') def hello(): return "Hello, World!" if __name__ == '__main__': server = DevServer() server.watch('your_app.py') # Replace 'your_app.py' with the name of your Python script server.serve()

Now, when you run your Bottle application with python your_app.py, it will automatically restart whenever 'your_app.py' or any other files it depends on are modified.

2. Using watchdog:

watchdog is a general-purpose file monitoring library that you can use to watch for file changes and restart your Bottle application accordingly. First, you need to install watchdog via pip:

pip install watchdog

Here's an example of how to use watchdog to restart your Bottle application:

import os import subprocess import time from watchdog.observers import Observer from watchdog.events import FileSystemEventHandler def restart_server(): try: if server: server.terminate() except Exception: pass # Replace 'your_app.py' with the name of your Python script subprocess.Popen(['python', 'your_app.py']) class MyHandler(FileSystemEventHandler): def on_modified(self, event): if event.src_path.endswith('.py'): restart_server() if __name__ == '__main__': event_handler = MyHandler() observer = Observer() observer.schedule(event_handler, path='.', recursive=True) observer.start() restart_server() try: while True: time.sleep(1) except KeyboardInterrupt: observer.stop() observer.join()

In this example, watchdog is used to monitor file changes in the current directory and its subdirectories (you can change '.' to the specific directory you want to watch). When a '.py' file is modified, it calls restart_server(), which restarts your Bottle application.

Choose the approach that best fits your development workflow and requirements.
