🔐 Security

The Rune Editor is built with security at its core:

• 🛡️ Secure memory management
• 🔒 Process isolation
• 🔑 Encrypted file operations
• 📝 Comprehensive logging

GhostC Language Support

GhostC is now integrated into the kernel, providing a lightweight scripting language for system automation and customization. Key features include:

• Basic type system (int, float, string, bool, array, struct)
• Built-in functions for I/O operations
• Stack-based execution model
• Heap memory management
• Symbol table for variable storage

Using GhostC

To use GhostC in your programs:

1. Include the GhostC header:

#include <ghostc.h>

2. Initialize the runtime:

GhostCRuntime* runtime = ghostc_init(1024, 4096);  // Stack size: 1024, Heap size: 4096

3. Execute GhostC code:

const char* source = "print('Hello from GhostC!')";
GhostCCompiler compiler = {0};
ghostc_compile(source, &compiler);
ghostc_execute(runtime, compiler.bytecode, compiler.bytecode_size);

4. Clean up:

ghostc_cleanup(runtime);

Hardware Compatibility

Raspberry Pi Zero W

The GhostC OS is optimized for the Raspberry Pi Zero W with the following specifications:

• 1GHz single-core CPU
• 512MB RAM
• Built-in WiFi and Bluetooth
• Mini HDMI port
• Micro USB ports

Zero W Specific Setup

1. Use a good quality power supply (5V 2.5A recommended)
2. Connect via mini HDMI (requires mini HDMI to HDMI adapter)
3. For keyboard, use a micro USB OTG adapter
4. WiFi is enabled but Bluetooth is disabled by default to save resources

Performance Optimizations for Zero W

• Display resolution set to 640x480 for better performance
• GPU memory limited to 32MB
• Bluetooth disabled by default
• Audio disabled by default
• USB power consumption optimized
• Initial CPU turbo boost enabled for 30 seconds at boot

Other Raspberry Pi Models

For other Raspberry Pi models (3B+, 4, etc.), edit kernel/config.txt and uncomment the following lines:

#hdmi_mode=16  # 1080p 60Hz
#gpu_mem=128
#dtparam=audio=on
#max_usb_current=1

SD Card Preparation and Booting

Prerequisites

• A micro SD card (minimum 4GB recommended)
• SD card reader
• For Zero W:
  • Mini HDMI to HDMI adapter
  • Micro USB OTG adapter for keyboard
  • 5V 2.5A power supply

Building the OS

1. First, build the kernel:

cd kernel
./build-os.sh

Preparing the SD Card

1. Insert your SD card into your computer
2. Identify your SD card device (you can use lsblk command)
3. Run the preparation script as root:

sudo ./prepare-sd.sh /dev/sdX  # Replace X with your SD card device letter

⚠️ WARNING: Be very careful with the device name. Using the wrong device could erase your system drive!

Booting GhostC OS

1. Insert the prepared SD card into your Raspberry Pi
2. Connect a monitor via HDMI
3. Connect a USB keyboard
4. Power on the Raspberry Pi

The GhostC OS will boot automatically and you'll see the GhostTerminal interface.

Default Configuration

The default config.txt settings are optimized for:

• HDMI output at 1080p
• USB keyboard support
• Basic GPIO functionality

You can modify these settings by editing the config.txt file before running the preparation script.

Troubleshooting

If you encounter boot issues:

1. Ensure the SD card is properly formatted
2. Verify all files were copied correctly
3. Check your power supply is adequate (recommended: 5V 2.5A)
4. Ensure your HDMI cable is connected before powering on
