“shouldn’t this have been published a few months ago?” yeah, probably. I even considered submitting it to the AoC contest. time is a real beast.
The title is clickbait. I did not design and implement a programming language for the sole or even primary purpose of leaderboarding on Advent of Code. It just turned out that the programming language I was working on fit the task remarkably well.
I can’t name just a single reason I started work on my language, Noulith, back in July 2022, but I think the biggest one was even more absurdly niche: I solve and write a lot of puzzlehunts, and I wanted a better programming language to use to search word lists for words satisfying unusual constraints, such as, “Find all ten-letter words that contain each of the letters A, B, and C exactly once and that have the ninth letter K.”1 I have a folder of ten-line scripts of this kind, mostly Python, and I thought there was surely a better way to do this.
