Prerequisites

• Deno

Setup

1. git clone this repository
2. cd into the repository

❗ Note: to start from scratch without my solutions, delete all the puzzle directories and the solver-factory.ts file in the lib directory.

Project Structure

📦
├─ lib/
│  ├─ yyDd/                       # puzzle directory for year `yy` and day `d`
│  │  ├─ input.txt                # input for the puzzle (git ignored)
│  │  ├─ puzzle.md                # problem description (git ignored)
│  │  └─ solver.ts                # solution for the puzzle
│  ├─ commands/
│  │  ├─ init.ts                  # command to scaffold a new puzzle directory
│  │  └─ solve.ts                 # command to solve a puzzle
│  ├─ tests/
│  │  ├─ main_test.ts             # unit tests for all the solvers
│  │  └─ main_test_answers.json   # correct answers for the puzzles
│  ├─ common.ts                   # common utility code
│  └─ solver-factory.ts           # factory for creating solvers
├─ deno.json                      # Deno configuration
└─ main.ts                        # entry point for the program

Usage

Solve the puzzle for the given year, day and part:

deno run solve [-d, --day <day>] [-p, --part <1 | 2>] [-y, --year <year>]

Initialize and scaffold a new puzzle directory into the lib directory:

deno run init [-d, --day <day>] [-y, --year <year>]

Defaults:

• day defaults to the day of the latest puzzle
• year defaults to the year of the latest AoC
• part defaults to 1

❗ Note: to use the init command to automatically scaffold a new puzzle directory and to fetch your input and problem description, you will need to set the AOC_SESSION environment variable to your Advent of Code session cookie. You can achieve this by creating a .env file with AOC_SESSION=<session cookie> in the root of your project (see .env.example). This same variable is also used to submit answers after solving a puzzle.

Testing

deno test will run all the solvers and test their output

❗ Note: the tests expects the lib/tests/main_test-answers.json file to contain the correct answers for the puzzles.
