Slack Slash command for Advent of Code leaderboard and competitions, including custom start times for people who don't want to compete at midnight EST.

Advent of Code Leaderboard Slash Command

This repository contains the code for a script that will run a Slash Command for a Private Advent of Code Leaderboard on Slack. This repo was originally forked from https://github.com/tomswartz07/AdventOfCodeLeaderboard and then expanded to be a slash command

Custom Start Times

For me, midnight EST is not a good time to attempt the challenges, so I've added /advent start as a way for users to mark their start time which results in a custom leaderboard. This of course requires participants not to cheat and peak at solutions.

Commands

• leaderboard: display the overall leaderboard ranked by stars
• today: display today's ranking ranked by how long each partipant took. Either from midnight EST, or when they used /advent start
• start: mark your custom start time
• details: dump the json used for informational purposes

Setup

Prerequisites:

• Python 3
• AWS Lambda
• AWS S3

Process:

1. Create a new Slack Slash Command and connect to AWS Lambda I followed this tutorial https://codeburst.io/building-a-slack-slash-bot-with-aws-lambda-python-d0d4a400de37
2. Log in to Advent of Code and obtain two things: the Private Leaderboard ID Number and a Session Cookie. See Session Cookie section for details.
3. Dump that info into a secrets.py file.

• Webhook URL goes in the SLACK_WEBHOOK variable
• Session goes in the SESSION_ID variable
• Leaderboard ID goes in the LEADERBOARD_ID variable.
  • The ID is the last part of the leaderboard url (https://adventofcode.com/2018/leaderboard/private/view/LEADERBOARD_ID)

5. Configure AWS S3 storage to keep track of custom start times. You could also use a database or any other storage solution you prefer.
6. Add AWS configuration parameters to secrets.py
7. Deploy and try /advent start
