Chapter 07: Extending General Bots

Architecture and deployment reference for developers.

Overview

BotServer is built in Rust with a modular architecture. Extend it by creating custom keywords, services, or entire applications.

Deployment Options

Method	Use Case	Guide
Local	Development	Installation
Docker	Production	Docker Deployment
LXC	Isolated components	Container Deployment

Module Structure

Module	Purpose
web_server	HTTP/WebSocket handling
basic	BASIC language runtime
llm	LLM provider integration
drive	Object storage
shared	Database models

Creating Custom Keywords

// In src/basic/keywords/my_keyword.rs
pub fn my_keyword(context: &mut EvalContext) -> Result<Dynamic, Box<EvalError>> {
    // Your keyword logic
    Ok(Dynamic::from("result"))
}

Register in keywords/mod.rs and rebuild.
