Advent of Code 2022

(ﾉ ◕ ヮ ◕)ﾉ*:･ﾟ ✧ Advent of Code 2022 (◕‿◕✿)

Setup

We'll need 2 env vars:

1. AOC_SESSION will hold your personal AoC session cookie
2. AOC_INPUT_PATH is the path to the input dir within this repo, eg. ~/code/aoc2022/input

echo 'export AOC_SESSION=<my-aoc-session>' >> .envrc.private
echo 'export AOC_INPUT_PATH=<my-aoc-input-path>' >> .envrc.private
direnv allow .

Use

scripts/comp.sh
scripts/solve.sh # current date
scripts/solve.sh 01 # specific day
scripts/solve.sh 2022 01 # specific date

Note: optimization in cabal.project is set to 0 for fast dev UX. Setting it to 1 can significantly speed up solvers.

Test

scripts/test.sh

Nix

build
aoc fetch --year 2022 --day 01
aoc solve --year 2022 --day 01

Dev

The project is using Nixkell

mkday.sh will fetch the input file and generate a template module and spec for it.

scripts/mkday.sh # current date
scripts/mkday.sh 01 # current year, specific day
scripts/mkday.sh 2022 01 # specific date

Formatting, Linting, Checking, etc...

treefmt
hlint .
scripts/shellcheck.sh
