TL;DR

A shell program to download inputs for Advent of Code puzzles.

This is probably a note to myself for 2023.

It needs to access the cookie session from an authenticated browser. In Firefox:

• open Advent of Code and open the Developer Tools
• go to the Network tab
• login if you haven’t yet, refresh otherwise
• look for cookie session in one of the fetched items
• save it in /path/to/local/session-cookie

You can call it in different ways:

/path/to/get-inputs.sh 2018 15      # 15th puzzle of 2018 edition

# in a directory named 2022
/path/to/get-inputs.sh 4            # 4th puzzle of 2022 edition

# in a directory named 2022, on December 13th
/path/to/get-inputs.sh              # 13th puzzle of 2022 edition

Here’s the code:

Enjoy!
