Advent of Nim 2022
I will be uploading my solutions here. <https://gitlab.com/al1ranger/aoc2022> Most likely I will not be able to complete all the challenges during the event, but I plan to do the unsolved ones afterwards.
Advent of Nim 2021
My attempts at solving the problems using Nim can be found at <https://gitlab.com/al1ranger/aoc2021>

I also encountered the same issue. It seems that parseBinInt silently truncates the bit string based on the width of int (the example in the problem had no X in the first four bits and hence 32 bit integers did not cause any problems).

Here's the repository with my solutions: <https://gitlab.com/al1ranger/aoc2020> This is also the first AoC I am participating in (and using it to learn Nim).
