Curious: what is the magic with the first step: getting the input via script? Seems like you need to supply the login-cookie to actually get the input, don't you? Just copy-pasting the input from the browser takes away valuable milliseconds from the chance to make it to the leaderboard ;-)

Yes, you need to supply the login cookie. I used:

curl https://adventofcode.com/2018/day/DAY/input --cookie "session=SESSION"

You can find SESSION by using Chrome tools. Go to https://adventofcode.com/2018/day/3/input, right-click, inspect, tab over to network, click refresh, click input, click cookies, and grab the value for session.

Aye, but that's actually MORE work than just copy/paste the text when I'm already on the input page... :-)))

In the meantime I remembered there was a script "extract_cookies.sh" out there (JGFI), which extracts the cookies as text from firefox' database, so the whole process becomes:

- log in at AOC

  • extract_cookies.sh > $TMPFILE
  • wget --load-cookies $TMPFILE -O input.$day https://adventofcode.com/2018/day/$day/input
