All years, all days, everything in Haskell
I've done every year in Haskell (2015 2016 2017 2018 2019 2020 2021), and so have several other people such as /u/glguy. I don't see if /u/mstksg has anything published for 2015 but they've done 2016 2017 2018 2019 2020 2021 along with some pretty good writeups, I recommend checking those out.

Jetbrains looks like it's about to release Compose ui for ios, and web!
I ran my own benchmarks for a whole ton of code at https://github.com/ephemient/aoc2021 on both Linux x64 and macos x64, and ended up disabling Kotlin/Native because it was varying between 10x and 100x slower than Kotlin/JVM, eventually timing out on CI. The generated code may be reasonable thanks to LLVM, but the runtime certainly is not.

Took a while for me to get around to completing this in Kotlin, Python, and Rust as well, since I was working on optimizing other solutions, but I finally made it.

So I switched tacks and implemented this in Kotlin, where mutation is easier. First version was brute-force with duplicate state avoidance (checked before the state explosion at every input), which worked quickly enough for part 1, but ran into OOMs for part 2. Once I replaced the HashSet with a custom LruSet (and later a simpler CacheSet which simply overwrites on hash collisions) it ran part 2 in a few minutes. I then ported this into Haskell.

Kotlin, Python, and Rust solutions are the same solution but much uglier.

I'm doing the same cached recursion in Kotlin, Python, and Rust.

I'm using dumber bounds in Kotlin, Python, and Rust since it was easier. But basically, assuming 0 ≤ all target x, we only need to check 0 ≤ 𝚫x ≤ max target x —anything else immediately overshoots the target— and assuming all target y < 0, we only need to check min target y ≤ 𝚫y ≤ max abs target y —anything smaller will immediately overshoot and anything larger will also overshoot after returning to origin.

Kotlin, Python, Rust all follow a similar approach, with bits being expanded from the hex characters on demand.
Looks somewhat similar in approach to mine, but instead of keeping track of the number of bits consumed myself, I simply re-use the position that it already keeps track of, plus a tiny bit of user-specified state so that I can parse directly from the hexadecimal representation, no need to build an intermediate String for the binary representation.

Is anyone doing the whole 2021 advent in Haskell?
I'm solving every day in Haskell, and translating or rewriting each into Kotlin, Python, and Rust.
