Advent of code 2023

Advent of Code 2023

This repository has some boilerplate, utils and setup for running Advent of Code easily.

It has built in support for Typescript, Ruby and Python.

Setup

Copy .env.example to .env, and set LANGUAGE to your desired value.

Log in on advent of code, and copy the session cookie to your the SESSION env var.

Now run nvm use and yarn install.

Running

To fetch inputs for a given day, run yarn setup [day], e.g. yarn setup 1. If run without a day, it'll fetch all days up to now.

To run your code, simply run yarn [your-language], e.g. yarn typescript. By default, yarn start runs yarn typescript - change this if you want.

This will run tests (if provided), execute your code, and send the solution. Solutoons will be deduped before sending.

Utils (typescript)

Typescript has some special utils in the utils/typescript folder. There are:

• .last as an extension method on Array. Let's be honest, it should always have been there.
• printGrid(grid: string[][]) to display a grid.
• visualisePoints(points: Record<string, Point[]>): creates a visual grid with marks at the specified points.
  • For example: visualisePoints({a: [0, 0], b: [0, 1]}) prints ab
• aStar is the A* algorithm
