Async Chain

Utility for chaining awaits

About

This package allows library developers to write interfaces that are both fluent and async, avoiding ugly syntax, like in the following example:

async def on_message(event):
    # bad!
    (await (await (await event.get_message()).get_author()).send_message("Hello world!"))

Instead, by marking all involved methods with the @async_chain.method decorator:

import async_chain

class MyEvent:
    @async_chain.method
    async def get_message(self):
        ...

The following syntax can be achieved:

async def on_message(event):
    # nice!
    await event.get_message().get_author().send_message("Hello world!")
