Common Lisp solutions to Advent of Code 2022

How to run

• Checkout this repository and my advent of code repository into ~/quicklisp/local-projects
• Load the package (ql:quickload "advent-of-code-2022")
• Change to package (in-package :aoc-2022)

Downloading input

(get-problem PROBLEM-NUMBER YEAR) will retrieve the input, cache it in a file, and return it as a string. It needs your session cookie set up in the advent-of-code package first.

Running problems

Generally running (dayN (get-problem N YEAR) :part P) will get the answer, where N is the day and P is 1 or 2. Some days are different though.
