Haskell solutions to Advent of Code 2020. Main repository for AoC solutions (which includes these as well) is here.

My goal for Advent of Code 2020 is to explore core Haskell & not use any external libraries. Most puzzles contain new things learned when solving the day & NOTES.md contain puzzle notes, extra challenges, and open questions.

Workflow

./dev.sh script is the one-stop for interactive development.

./dev.sh day-number [assert] [lint]

Running it with no optional args, script starts a GHCi session & pulls input data (adventofcode.com session cookie value needs to be stored in a .cookie file. Saves me 10 seconds every day, I know).

• assert compares puzzle output correct answers from solutions folder
• lint runs hlint and checks for GHC warnings.
