Advent of Code

This is a multi-language repository, for easy usage, all of them share the same root level. You need to individually set up each language you wish to use.

Usage

The repository does not contain task inputs as my own inputs are located in a private repository. If you wish to use this repository with your own inputs provide them in the following folder structure:

resources
├── 2015
│   ├── 01
│   │   └── input.txt
│   ├── 02
│   │   └── input.txt
│   │  ...
│   └── 25
│       └── input.txt
│   ...
└── 2023
    ├── 01
    │   ├── example.1.txt
    │   ├── example.2.txt
    │   └── input.txt
    │  ...
    └── 25
        └── input.txt

Working with private files

If you wish to replicate the same input setup that I have so that it's compliant with Advent of Code's rules, you should not keep your inputs in a publicly hosted repository. I think the best solution to this is to keep them in a private submodule, keeping your inputs private, but your solutions public and keeping your CI happy and operational.

Why?

See the "Can I copy/redistribute part of Advent of Code?" section at https://adventofcode.com/2023/about

How?

Collect your input files into a new "advent-of-code-inputs" repository
Get a fresh clone of your repository!
Install git-filter-repo

You will completely rewrite your repository's history, so first educate yourself on how git-filter-repo works. (The tool you might find for this first is the BFG Repo cleaner, however git-filter-repo is much more capable and can clean out huge repositories in just milliseconds.)
Clean out the repository: git filter-repo --invert-paths --path-glob '*.txt' --path inputs

This is just an example command, add more globs or paths if needed
Verify that apart from the unwanted files everything is in order. Check older commits too!

Maybe in previous years you stored these files differently, and/or you refactored them at some point!

Add back your inputs as a git submodule:

git submodule add git@github.com:AlexAegis/advent-of-code-inputs.git resources
git commit -m 'added inputs submodule'

Adjust your CI so that it checks out submodules too.

If you're using GitHub Actions and actions/checkout:

- name: checkout
  uses: actions/checkout@v4
  with:
    fetch-depth: 1
    submodules: true

Verify if everything works locally
If everything looks right, re-add your remote and force push the changes. (Since you started with a fresh clone, your old can be used to restore it if anything goes wrong at any point)
```
git remote add origin git@github.com:AlexAegis/advent-of-code.git
git push --force
```
Clean out remaining branches by either force pushing them too or just removing them.
