Advent of Code Progress Announcer

Posts messages to Slack whenever someone gets a new star in Advent of Code.

Installation

Install the requirements with composer install.

Copy .env.example to .env and edit it:

SESSION_COOKIE is a valid AoC session cookie - use your browser's inspector.
LEADERBOARD is the ID of the leaderboard. It's in the leaderboard URL, but it's also the ID of the owner.
SLACK_URL is a valid Slack Incoming Webhook.

Now configure something, like cron, to run run.php every 15 minutes. Don't run it more often than that - the AoC servers don't like that.
