🧩 Generating a Puzzle Day

Quickly scaffold a new Advent of Code puzzle day:

bun run puzzle:generate

This command will:

1. Prompt you for the year, day number, and puzzle name.
2. Generate a folder structure under:

apps/<year>/day-<day>/
  ├─ puzzle.ts        # Puzzle solution template
  ├─ puzzle.test.ts   # Test template
  ├─ package.json     # Minimal package for the day
  ├─ sample.txt       # Sample input
  └─ input.txt        # Puzzle input

3. Run bun install in the root folder to ensure dependencies are up to date.
4. Display next steps, including:

• Updating input.txt and sample.txt.
• Renaming methods in puzzle.ts to something more descriptive.
• Running tests in watch mode

🧪 Running Tests

To run unit tests for Day 1 in watch mode:

bun test apps/2025/day-01 --watch

Tests will automatically rerun on file changes.

⚡ Updating Badge & Performance Table

Once you have completed a puzzle day, update your progress badge and performance table:

bun run puzzle:snapshot

This will regenerate the badge data to reflect your latest progress and performance.
