Crate ctx 

ctx - Code intelligence library for AI-assisted development.

This library provides tools for understanding codebases and generating context for Large Language Models (LLMs). It includes:

• Code Indexing: Parse and index source code with symbol extraction
• Semantic Search: Find relevant code using embeddings
• Call Graph Analysis: Understand code relationships and impact
• Smart Context Selection: Intelligently select files for LLM context
• Diff-Aware Context: Generate context focused on code changes
• Token Management: Count and budget tokens for LLM context windows

Quick Start

use ctx::{index::Indexer, db::Database, smart::{smart_context, SmartConfig}};
use ctx::embeddings::LocalProvider;

// Index a codebase
let mut indexer = Indexer::new("./my-project", false)?;
indexer.index()?;

// Open the database
let db = index::open_database("./my-project")?;

// Generate smart context for a task
let provider = LocalProvider::new()?;
let config = SmartConfig::default();
let context = smart_context(&db, &analytics, &provider, "add caching", config)?;
