SDK](https://dotnet.microsoft.com/download/dotnet/10.0)\n- [AOC_SESSION_KEY](#getting-your-session-key) environment variable (optional, for fetching inputs)\n\n### Running a specific day\n\n```bash\ndotnet run --project Runner -- \u003cyear\u003e \u003cday\u003e\n```\n\nExample:\n```bash\ndotnet run --project Runner -- 2024 1\n```\n\n### Running tests\n\n```bash\ndotnet test\n```\n\n## Project Structure\n\n```\nAdventOfFSharp/\n├── Year20XX/           # Solutions for each year\n│   ├── Day01.fs\n│   ├── Day02.fs\n│   └── ...\n├── Common/             # Shared

documentation\n    └── scaffold.py     # Scaffold new day files\n```\n\n## Scripts\n\n### Generate Wiki\n\nGenerates wiki documentation from solution headers:\n\n```bash\npython scripts/gen_wiki.py\n```\n\nThis creates:\n- `wiki/difficulty.md` — solutions by difficulty\n- `wiki/tags/index.md` — tag directory\n- `wiki/tags/{tag}.md` — per-tag pages\n- `YearXXXX/README.md` — per-year tables\n\n### Scaffold New Day\n\nCreates boilerplate for a new day:\n\n```bash\npython scripts/scaffold.py \u003cyear\u003e \u003cday\u003e\n```\n\nExample:\n```bash\npython scripts/scaffold.py 2024 15\n```\n\nThis creates:\n- `Year2024/Day15.fs` — solution module\n- `Inputs/2024_15.txt` — input file (fetched if AOC_SESSION_KEY is set)\n\n## Getting your session key\n\n1. Log in to [Advent of Code](https://adventofcode.com)\n2. Open browser dev tools → Application/Storage → Cookies\n3. Copy the `session` cookie value\n4. Set it as environment variable:\n   ```bash\n   export AOC_SESSION_KEY=\"your_session_cookie\"\n   ```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcode-shoily%2Fadventoffsharp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcode-shoily%2Fadventoffsharp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcode-shoily%2Fadventoffsharp/lists"}
