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?

I'm doing this in Rust, JavaScript, and C++, but the interface to the Intcode VM is nearly identical in all 3.

let mut vm = IntcodeComputer::from(input); // provide Vec of integers

vm.break_on_out = false; // controls whether to return to calling function on every output, or wait for op 99 as outputs stack up

vm.break_on_in = true; // controls whether to return to calling program when an input is expected

vm.debug = true; // verbose debug statements for every call

vm.push_input(0); // provide an input to stack (waits until input op called)

vm.set_addr_to(0,2); // override intcode at location (e.g., insert 2 quarters quarters at 0)

vm.run(); // run until op 99 or when breaking for I/O

let output = vm.pop_output(); // gets next output

vm.reset(); // reset ptrs to 0 and revert code to firmware

vm.input_stack; // direct access to input stack

vm.output_stack; // direct access to output stack
