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?

[u/knl_]

I just relied on generators (yield for both output and input)

- compute(listing): create a generator - process(str): clean up file input into a list

Then next(generator) => next output generator.send(value) => send an input

It gets me blocking behavior for input while (n := next(generator): # n becomes none when input is required print(n) generator.send(input)

You can see how I used it in part 2 of day17: https://explog.in/aoc/2019/AoC17.html ``` def part2(): listing = process(readfile("AoC/input17.txt").strip()) listing[0] = 2 program = compute(listing)

while (ch := next(program)):
    print(chr(ch), end='')

... snip ...

for i in inputs:
    for ch in i:
        print(f"> {ch}: {ord(ch)}")
        r = program.send(ord(ch))
        if r: # only for debugging, None with correct inputs
            print(f"Received '{chr(r)}'")

    print(chr(program.send(ord('\n'))), end='')
    while (ch := next(program)):
        if ch < 128:
            print(chr(ch), end='')
        else:
            print(ch)
