These are my solutions to Advent of Code, written in Nim. During 2021 I began solving in dart (See my repo aoc_dart), but switched to Nim after day 7 because I missed tuples soo much.
Please see perf.nim for how measurements are taken. Briefly, I use a macro to import every solution at compile time and generate statements that call measure on each part for each solution. Parts are measured either until they've been run 1000 times or until the total time exceeds 10 seconds. Time it takes to fetch and/or read the input is not included in the measurement (The parsing of the input within the solution still is counted of course).
I compile it with nim c -d:danger -d:release --opt:speed --passC:'flto' -r perf.nim
