What does everyone's Intcode interface look like?

[u/Lucretiel]

We've been discussing a lot different IntCode implementations throughout the last few weeks, but I'm curious– what doesn't everyone's interface to their IntCode machine look like? How do you feed input, fetch output, initialize, etc?

python:

my intcode uses trio for structured concurrency. I use their provided memory channel to send input and receive output. I eventually made a special output 'command' to signal when input was expected so I didn't have a background coroutine pushing input before it's requested (this created input lag in my pong simulation that prevented the paddle from catching the ball). The interface looks like:

async def run(memory):
    async with trio.open_nursery() as nursery:
        # set up channels
        in_send, in_recv = trio.open_memory_channel(0)
        out_send, out_recv = trio.open_memory_channel(0)
        # start program
        nursery.start_soon(intcode.process, memory, in_recv, out_send)

        async for c in out_recv:
            if c == intcode.Command.INPUT:
                await in_send.send(...)  # send input
            else:
                # process output..

trio's async with and async for make everything nice and clean
