# Beacon

A modern digital signage application for displaying church events, built with Rust and Iced.

## Features

- Real-time event display with automatic updates
- Smooth image loading and transitions
- Modern, clean interface design
- Automatic event filtering based on date/time
- Support for high-resolution displays
- Efficient memory management for images

## Requirements

- Rust 1.70 or higher
- A running church API instance with events endpoint

## Configuration

You can configure Beacon in three ways (in order of precedence):

### 1. Environment Variables
Configure Beacon using environment variables:
```bash
export BEACON_API_URL="https://your-api-url.com"
export BEACON_WINDOW_WIDTH="1920"
export BEACON_WINDOW_HEIGHT="1080"
./beacon
```

### 2. .env File
Create a `.env` file in the application directory:
```bash
# Copy the example file
cp .env.example .env
# Edit with your settings
nano .env
```

Example `.env` file:
```env
BEACON_API_URL=https://your-api-endpoint.com
BEACON_WINDOW_WIDTH=1920
BEACON_WINDOW_HEIGHT=1080
RUST_LOG=beacon=info
```

Available environment variables:
- `BEACON_API_URL` - API endpoint URL
- `BEACON_WINDOW_WIDTH` - Window width in pixels  
- `BEACON_WINDOW_HEIGHT` - Window height in pixels

### 3. Config File
Create a `config.toml` file in the application directory:

```toml
api_url = "https://your-api-url.com"
window_width = 1920
window_height = 1080
slide_interval_seconds = 10
refresh_interval_minutes = 5
```

**Configuration Precedence:**
1. Environment variables (highest priority)
2. .env file 
3. config.toml file (lowest priority)

## Building

```bash
cargo build --release
```

## Running

```bash
./target/release/beacon
```

## Development

The application is built using:
- Iced for the UI framework
- Tokio for async runtime
- Reqwest for HTTP requests
- Chrono for date/time handling
