AdventOfCode20xx

Solutions to the Advent Of Code 20xx with C# (.NET 8). The goal is to make it a personal learning experience, and make it somewhat readable (by e.g. improvements suggested by GitHub Copilot or ChatGPT). These are by no means "optimal" or the most concise/clear solutions.

Solution Completion Table

Note that there's a seperate repository for 2021 in Haskell: p-kostic/AdventOfCode2021 for Days [1-11, 13p1] before I ragequit when I encountered "stateful" puzzles that require the extensive use of e.g. Records and/or Lenses).

Template from sindrekjr/AdventOfCodeBase. Below is some of the template's original documentation to get you started for when you want to run it locally.

Running locally for when you clone/fork this project

Create config.json with the following key/value pairs. If you run the program without adding a config.json file, one will be created for you without a cookie field. The program will not be able to fetch puzzle inputs from the web before a valid cookie is added to the configuration.

{
  "cookie": "c0nt3nt",
  "year": 2023,
  "days": [1] 
}

• cookie - Note that c0nt3nt must be replaced with a valid cookie value that your browser stores when logging in at adventofcode.com. Instructions on locating your session cookie can be found here: wimglenn/advent-of-code-wim#1. NOTE: the "session=" prefix must be excluded.
• year - Specifies which year you wish to output solutions for when running the project. Defaults to the current year if left unspecified.
• days - Specifies which days you wish to output solutions for when running the project. Defaults to current day if left unspecified and an event is actively running, otherwise defaults to 0.

The days field supports list comprehension syntax and strings, meaning the following notations are valid.

• "1..4, 10" - runs day 1, 2, 3, 4, and 10.
• [1, 3, "5..9", 15] - runs day 1, 3, 5, 6, 7, 8, 9, and 15.
• 0 - runs all days

Running the project

Write your code solutions to advent of code within the appropriate day classes in the Solutions folder, and run the project. From the command line you may do as follows.

> cd AdventOfCode
> dotnet build
> dotnet run

Using dotnet run from the root of the repository will also work as long as you specify which project to run by adding -p AdventOfCode. Note that your config.json must be stored in the location from where you run your project.

Notes

Generating Previous Year's Solution Files

Use the included PowerShell script AdventOfCode/UserScripts/GenerateSolutionFiles.ps1 to generate a year's solution files following the same layout as those already included.

Usage: GenerateSolutionFiles.ps1 [-Year <Int>]

If no value is provided it will generate files for the current year. The script will avoid overwriting existing files.

Requires PowerShell v3 or later due to the way $PSScriptRoot behaves. If you have Windows 8+ you should be set. Upgrades for previous versions, and installs for macOS and Linux can be found in Microsoft's Powershell Documentation
