#!/usr/bin/env fish
#
# This is a fish script to pull the input file of the specific day.
#
# In order to execute, run:
#
# set -x AOC_SESSION "<session key>"
# . ./prep.fish <day>
#
# where "key" is the session key in your logged-in cookie, and "day" is
# the day you want to prep.
#
# Credit where it is due, the concept of this script was inspired heavily by 0xdf's version.
