alenia-nerve 1.3.5

Ultra-fast cross-platform local IPC engine for sovereign game developers.

Nerve — Decentralized Nervous System for Local Sockets

Sovereignty, Speed, and Complete Privacy. Nerve is the cross-platform local inter-process communication engine designed by Alenia Studios to orchestrate game development tools locally, requiring zero cloud dependency.

---

The Concept: Sovereign Local Networks

In modern game development, the privacy of your assets, source code, and metadata is paramount. Nerve acts as an ultra-fast local data bus, allowing independent processes (such as sprite slicers, gif renderers, and system monitors) to sync in real-time with sub-millisecond latency, without sending a single byte outside your physical workstation.

---

Multi-Platform Native Core (UDS & TCP)

Nerve is fully cross-platform and dynamically adapts to the host operating system to deliver the best local latency possible:

• Linux & macOS: Utilizes native Unix Domain Sockets (UDS) via socket.AF_UNIX at /tmp/nerve.sock for high-performance direct memory piping.
• Windows: Dynamically falls back to a specialized local TCP connection via socket.AF_INET at 127.0.0.1:50505, ensuring 100% compatibility across developer workstations without modifying a single line of your tools' logic.

---

v1.3.3 Concurrency, Security & Stability Updates

Nerve has been heavily upgraded to offer production-grade resilience and studio identity:

• Industrial Auto-Reconnection: NexusClient features automatic background reconnection loops. If the connection drops or the Hub restarts, the client attempts connection every 2 seconds indefinitely, preserving the host application from crashes and registering back smoothly as soon as the Hub comes online.
• Resilient JSON Validation: The Hub evaluates incoming packets robustly. If corrupted or invalid payloads are sent, it registers an [NERVE] Invalid Payload error and proceeds without dropping the client socket or crashing the system.
• Background Heartbeats (Latido): The Hub broadcasts verification ping packets ({"type": "ping"}) every 5 seconds to actively monitor and purge stale, dead or silently dropped connections, freeing up system sockets.
• Aesthetic Colored Console: Enhanced interactive experience featuring beautiful Alenia purple banners, success green logs, warning orange, and failure red errors using standard ANSI colors.
• Verbose Mode: Run the server with --verbose or -v flags to print a detailed, colored trace of every single message routed through the Hub.
• External Configuration Support: Easily configure ports and socket paths without altering code. Create a nerve.config file in your root folder as JSON or simple key-value text.

---

Configuration File (nerve.config)

To customize socket paths or TCP ports globally, place a nerve.config file in your project's working directory.

Option A (JSON Format):

{
  "socket_path": "/tmp/nerve.sock",
  "port": 50505,
  "host": "127.0.0.1"
}

Option B (Simple Text Format):

socket_path=/tmp/nerve.sock
port=50505

---

Key Features

• Cross-Platform: Zero configuration required; runs out-of-the-box on Windows, Linux, and macOS.
• Line-Based Framing: Robust packet handling using newline delimiters (\n) to prevent data collision or buffer merging under heavy throughput.
• Hub-Client Architecture: A single central coordinator (NexusHub) directs intelligent message routing to specific registered nodes (NexusClient).
• Console Command Interface (CLI): Spawn and manage the hub globally from any terminal with a simple command.

Where Nerve Shines: Global Use Cases

Nerve is not just for game development. It is a zero-dependency, ultra-fast solution for any Local Inter-Process Communication (IPC) problem in Python. Here is where you can leverage its power:

1. Local Microservices (Desktop Applications)

• The Context: You are building a modern desktop app with a frontend in Electron, Tauri, or Flutter, and a heavy backend in Python for AI or data processing.
• Why Nerve: Instead of spawning a local HTTP server (like Flask or FastAPI) that consumes network ports and adds overhead, use Nerve to pass messages via native sockets at sub-millisecond speeds. It supports native bi-directional pushing without polling.

2. AI Pipelines & Real-Time Data Processing

• The Context: You have a local AI pipeline where one process captures video or audio, another process (running PyTorch or TensorFlow) analyzes the data, and a third process logs results.
• Why Nerve: If the AI model crashes due to VRAM exhaustion, the capture process doesn't die. Nerve handles automatic reconnection seamlessly. Line-based framing ensures high-speed message passing without buffer corruption.

3. Local DevOps & Automation Orchestration

• The Context: You run multiple background automation scripts on your workstation or server (e.g., log cleaners, disk monitors, auto-backup scripts) and need them to coordinate.
• Why Nerve: No need to write to shared lock-prone files or setup a local database just to share state. Scripts can broadcast events and a dedicated logger client can aggregate all outputs into a single clean stream.

4. Polyglot Bridge (Multi-Language Integration)

• The Context: Part of your system is in Python due to its rich ecosystem, but performance-critical parts are written in C++, Rust, or Go.
• Why Nerve: The protocol is extremely simple: JSON strings delimited by a newline (\n). Any language that can open a standard network or Unix socket can connect to the Nerve Hub and talk to your Python nodes without complex C-bindings or heavy RPC frameworks.

Installation

We highly recommend installing this tool inside an isolated virtual environment to comply with modern OS security standards (PEP 668) and avoid dependency conflicts.

# 1. Create a virtual environment
python3 -m venv alenia_env

# 2. Activate it
# On Linux/macOS:
source alenia_env/bin/activate
# On Windows:
alenia_env\Scripts\activate

# 3. Install the engine
pip install alenia-nerve

Note for global installation: If you prefer a system-wide installation (e.g., inside Docker or specific CI/CD pipelines) and are aware of the risks, you can bypass the OS restriction flag:

pip install alenia-nerve --break-system-packages

---

Command Line Interface (CLI)

Once installed, you can start the Nerve Hub globally from any terminal shell:

nerve start

For detailed message routing traces, run:

nerve start --verbose

Help Menu:

nerve --help

---

Simple Integration Example

1. Initialize the Client

Connect to the local hub by registering a unique client ID.

from nerve import NexusClient

client = NexusClient()
client.connect("my_tool_id")

2. Send Message to a Specific Node

Send any JSON-serializable payload directly to another registered node:

payload = {"progress": 100, "status": "COMPLETED"}
client.send("other_tool_id", payload)

3. Broadcast to All Nodes

Broadcast any payload to every other client currently connected to the hub:

client.broadcast({"event": "asset_ready", "path": "/assets/knight.png"})

4. Listen for Incoming Stream

Register an asynchronous callback function to listen to data streams in real-time:

def handle_incoming(data):
    print(f"Received: {data}")

client.listen(handle_incoming)

5. List Connected Nodes

Query the hub for all currently registered client IDs:

nodes = client.list_clients()
print(nodes)  # ['renderer', 'monitor', 'logger']
