Advent Of Code

My Advent of Code Solutions.

I have built a framework that automates downloading inputs, but also submitting the answers.

Setup

Create file .env, adding in your AdventOfCode session token.

Example format is available in .env.sample

Dependencies

You will need GTK (cairo) installed to run the window library. https://github.com/Automattic/node-canvas/wiki/Installation:-Windows

Run npm install to install dependencies.

Download FFMPEG-git-full from https://www.gyan.dev/ffmpeg/builds/

Usage

Run day scripts using node 2021/01.js (for example).

Your unique puzzle input will be automatically downloaded.

To submit an answer, run node 2021/01.js --submit. Without this, the answer will be generated, but not submitted to AoC.

To generate a year's solution files from template, run node generate_files.js [YEAR]

Libs

Window

Creates a window that can render pixels.

Run with --render to automatically capture the window as a video.

Copy ffmpeg.exe into bin/ to get video support.

import Window from '../lib/window.js';

// create window with defined width and height (in pixels)
const W = new Window({ width: 5, height: 5 });

// set a pixel colour
W.setPixel(0, 0, Window.green);

// set arbitrary data on each cell
W.setKey(0, 0, 'wall', true);

// loop over all cells in window
W.forEach((cellObj, x, y) => {

});

// start window renderer
W.loop();
