#Advent of Code \o/

is this some leaderboarder's highly-optimized, highly-readable solutions?


I try to optimize some when I have free time, golf solutions aren't even the best. do you like code-golfing? check out this repo!

long, modular solutions are always documented, but rarely (if not at all) unit-tested


  • no custom library imports (only stdlib)
  • each puzzle is standalone. they can be run using the standard compiler/interpreter
  • standard I/O is used for input and output

does this have solutions in my favorite programming language?

take a look at the language usage breakdown, if the git forge you're reading this from supports it.

if it doesn't support it, then there's a good chance that you're a shell literate! cook up a oneliner to analyze my file types here...

find 20?? ! -name '*.md' ! -name '*.txt' -type f | sed 's/.*\.//' | sort | uniq -c | sort -bnr

the .jpg files are probably screenshots of Apple Shortcuts solutions (mostly 2021), so they are in fact valid file types of solutions.

as of writing:

  45 py
  15 jpg
  14 go
   7 lua
   4 cpp
   2 sh
   2 moon

do you have a neat setup for input and submitting?

yeah, but not exactly neat

do you have a neat script or templates which you use to create new directory structures?


check out bin/new

templates at skel/

pretend this is actual installable software and document how a user should set it up


  • python
  • cargo
  • any other language you wish to run

install 'dependencies' (lol)

  • https://github.com/scarvalhojr/aoc-cli
  • set up direnv
    • set $AOCROOT to the path to this git repo in the .envrc of the parent dir of the repo
    • check envs using bin/new --help
  • create virtualenv
  • activate virtualenv
  • install from requirements.txt
  • start solving new puzzles as they come, using bin/new

are you going to (eventually) do all the previous puzzles?
