A decently command-line interface I made because I was bored.
(Don't use this too frecuently, the AoC servers can only handle so much requests, so this CLI may cause problems if used too frecuently)
This CLI requires node version 8.x.x or greater.
You can install this using npm or yarn:
$ npm i -g advent-of-code-cli
$ yarn global add advent-of-code-cli
To run the CLI, run the following command:
$ aoc
A menu should pop up, where you must enter your session cookie to send with requests.
(If you don't have a session cookie, you can grab it on the "Application" tab of mostly any browser's DevTools, stored as "session" in the site cookies)
