Advent of Code

This repo contains my attempts for AOC 2020 - 2022.

Running the codes

• Running a specific day

  shards run day01

• Running tests

  crystal spec spec/file_spec.cr

or just

crystal spec

Running the codes (2021 & 2020)

cd into the year folder, and start a nix-shell with

nix-shell

Open your editor of choice (Vscode for me) in the nix-shell

code .

This will give the editor access to the GHC and the Haskell language server.

All sample inputs are stored in test.in and the full input in input.in.

Compile and run Haskell programs with runhaskell and pipe the input with stdin.

runhaskell filename.hs < test.in
