Hello World

This section shows you how to write a hello world program using xronos. Create a file called hello.py and paste the following content into it.

import xronos

class Hello(xronos.Reactor):
    @xronos.reaction
    def hello(self, interface):
        interface.add_trigger(self.startup)
        return lambda: print(f"Hello, world!")

env = xronos.Environment()
env.create_reactor("hello", Hello)
env.execute()

If you see the following output, the library is installed successfully.

$ python hello.py
Hello, world!
