# Luanti-Web: A dynamic website-toolkit

Welcome to the Luanti Web Generator! Born from a passion for creative sandbox gaming, this hobby project provides a powerful, automated toolkit for generating a beautiful and feature-rich static website for your Minetest or Luanti server. Showcase your server, worlds, track your players, and inform your community.

This system is designed from the ground up to be modular, easily configurable, and perfect for small communities who want web presence without the hassle.

# ✨ Features

* **Automated Map Generation:** Leverages `minetestmapper` to create high-resolution PNG maps of your game worlds.
* **Tiled Map Generation:** Uses `gdal2tiles.py` to create performant, zoomable map tiles for a smooth user experience.
* **Dynamic Map Viewer:** Implements an interactive map viewer using [Leaflet.js](https://leafletjs.com/), powered by the generated map tiles.
* **Live Player Tracking:** Dynamically fetches and displays player locations as markers on the live map.
* **Map Archive:** Automatically saves a daily snapshot of the map and makes it available through a dropdown viewer on the world detail page.
* **Template-Driven Site Generation:** Builds all static HTML pages from simple, customizable templates.
* **Flexible Configuration:** Configuration is easy with a central global config and a sub-config file for every of your worlds.
* **Automation-Ready:** Designed for unattended execution via scheduling tools like cron.

# 🔧 Prerequisites

To run this system, the following software packages must be installed on your server:

* **bash:** The scripting language used for the entire project.
* **ImageMagick:** Required for `identify` (to read image dimensions) and `convert` (to resize images).
    * *Debian/Ubuntu Install:* `sudo apt-get install imagemagick`
* **GDAL/OGR:** Provides the `gdal2tiles.py` script for tile generation.
    * *Debian/Ubuntu Install:* `sudo apt-get install gdal-bin python3-gdal`
* **minetestmapper:** The executable used to render maps from world data. This must be placed within the project directory.
* **Web Server:** A web server like Nginx or Apache is needed to serve the generated static files.

# ⚙️ Installation & Setup

### 1. Clone the Repository

First, clone or copy all project files to a base directory on your server, such as `/opt/luweb/`.

```
git clone https://git.geigernet.eu/rainer/luanti-web.git /opt/luweb
cd /opt/luweb
chmod +x generate_map.sh generate_site.sh
```

### 2. Global Configuration

The main configuration file is `config.sh`. You must edit this file to match your server's environment.

**Key variables in `config.sh`:**

* `BASE_SCRIPT_DIR`: The root directory of the project (e.g., `/opt/luweb`).
* `MINETESTMAPPER_WORLD_DATA_BASE_PATH`: The path to your Minetest/Luanti worlds' data directory (e.g., `<server-path>/worlds/`), docker compatible.
* `WEB_ROOT_PATH`: The document root of your website where the generated files will be placed (e.g., `/var/www/your-domain.com/web`).
* `LOG_DIR_BASE`: The directory where log files will be written (e.g., `/var/log/luweb`).

### 3. Per-World Configuration

For each world you want to feature on the website, a `web.conf` file must exist within that world's data directory (e.g., `<server-path>/worlds/my_world/web.conf`). This file allows you to override global defaults with world-specific settings.

A minimal `web.conf` could look like this and is automatically created for every detected world in your `MINETESTMAPPER_WORLD_DATA_BASE_PATH`:

```bash
# Display name for the world
WORLD_DISPLAY_NAME="My Creative World"

# Server connection details
SERVER_ADDRESS="your-server.com"
SERVER_PORT="30001"

# A short description for the world overview page
WORLD_SHORT_DESCRIPTION="A brief, catchy description of this world."

# A detailed HTML description for the world's detail page
WORLD_LONG_DESCRIPTION="<p>A longer description with <b>HTML</b> support.</p>"
```

# 🚀 Usage

The scripts are designed to be run from the command line, either manually or via automated jobs.

### 1. Map and Tile Generation

The `generate_map.sh` script creates the map, tiles, and archive images for a specific world. It must be called with the "world key" (the name of the world's directory) as an argument.

```bash
# Generate map assets for the world located in the 'world' directory
./generate_map.sh world
```

### 2. Website Generation

The `generate_site.sh` script builds the entire website (overview, detail pages, etc.). It scans all configured world directories and creates a detail page for each one.

```bash
# Generate the complete website
./generate_site.sh
```

### 3. Automation (Cronjob)

For fully automatic operation, setting up cronjobs is recommended.

**Example for `crontab -e`:**

```bash
# Generate map assets for the 'world' every 30 minutes
*/30 * * * * /opt/luweb/generate_map.sh world >> /var/log/luweb/cron.log 2>&1

# Re-build the website every 12 hours
* */12 * * * /opt/luweb/generate_site.sh >> /var/log/luweb/cron.log 2>&1
```
