Advent of Code Go

Welcome to the Advent of Code Go project! This repository contains the solutions for the Advent of Code (AoC) - an annual set of Christmas-themed programming challenges.

Getting Started

Before you can start using this project, make sure you have Go installed on your system as this project assumes a Go development environment.

Prerequisites

• Go (1.21 or higher is recommended)
• Advent of Code session cookie (to fetch puzzles and inputs)

Setup

1. Clone the repository to your local machine:

   git clone https://github.com/mupkoo/advent-of-code-go.git
   

2. Navigate to the repository directory:

   cd advent-of-code-go
   

Usage

This project comes with a Makefile which simplifies several common tasks:

Show Help

To display a list of available make commands:

make help

Install Dependencies

go mod tidy

Check AoC Session Cookie

Ensure your AoC session cookie environment variable is set. This is required to fetch the challenges and inputs automatically:

export AOC_SESSION_COOKIE=your-session-cookie
make check-aoc-cookie

Generate Skeleton Code

Generate skeleton Go files for a specific day and year (if not provided, defaults to the current year). Replace $DAY and $YEAR with desired values:

make skeleton DAY=1 YEAR=2023

Fetch Challenge Input

Download the input for a specific day and year. The AoC session cookie is required:

make input DAY=1 YEAR=2023

Fetch Challenge Prompt

Retrieve the prompt for a specific challenge using:

make prompt DAY=1 YEAR=2023

Good luck and happy coding this Advent season!
