python 脚本自动重载

利用flask自带的werkzeug模块实现

# 监控脚本
# 首先需要 pip install flask
# pymonitor.py
def run_with_reloader(main_func, args=(), kwargs=None,
                      extra_files=None, interval=1,
                      reloader_type='auto'):
    """Run the given function in an independent python interpreter."""
    import os
    import sys
    import signal
    import threading
    from werkzeug._reloader import reloader_loops
    reloader = reloader_loops[reloader_type](extra_files, interval)
    signal.signal(signal.SIGTERM, lambda *args: sys.exit(0))
    try:
        if os.environ.get('WERKZEUG_RUN_MAIN') == 'true':
            t = threading.Thread(target=main_func, args=args, kwargs=kwargs)
            t.setDaemon(True)
            t.start()
            reloader.run()
        else:
            sys.exit(reloader.restart_with_reloader())
    except KeyboardInterrupt:
        pass

# 运行脚本
import time

from pymonitor import run_with_reloader


def main(name, age):
    while True:
        print("hello, ", name, '!')
        time.sleep(2)
        print(age)


if __name__ == '__main__':
    run_with_reloader(main, args=('man', 20))
