A CLI tool to help you run and test your Advent of Code solutions across different programming languages.

## Features

- 🚀 Run solutions in multiple languages (Python, JavaScript, Java, C++, Ruby)
- 🔄 Watch mode for automatic re-runs
- 🎨 Beautiful terminal UI with spinners and colors
- 📡 Auto-fetch puzzle inputs
- 🧪 Test your solutions with sample/real inputs
- 📊 Track your progress and performance

## Installation

You can use the tool in two ways:

### Option 1: Using npx (Recommended)
```bash
# Run directly without installation
npx @nguyenhuu/adventofcode

# Or with specific command
npx @nguyenhuu/adventofcode --year 2024 --day 1 --part 1 --language python
```

### Option 2: Global Installation
```bash
# Install globally
npm install -g @nguyenhuu/adventofcode

# Run the tool
adventofcode
```

## Setup

Save your `session` cookie into `.env` file in the root folder:
```

## Telemetry

This application collects anonymous usage data to help improve the user experience. The data collected includes:

- Event types (execution, submission, input fetch, key press)
- Basic context (year, day, part, language, input mode)
- Application version and platform

No personal information is collected. The data is used to:
- Understand usage patterns
- Identify common issues
- Guide future improvements

### Opting Out

You can opt out of telemetry in two ways:

1. Using the command line option: `--disable-telemetry`

2. Using an environment variable: `DISABLE_TELEMETRY=true`
