Crate llmgrep 

llmgrep - Pattern-based code search powered by Magellan.

This library provides pattern-based code search capabilities using Magellan’s code graph database. It supports symbol search, reference search, call search, AST-based filtering, and algorithm-based analysis.

Features

• Symbol Search: Find symbols by name with fuzzy matching
• Reference Search: Find incoming references to symbols
• Call Search: Find outgoing function calls from symbols
• AST Filtering: Filter by AST node kind (functions, loops, etc.)
• Metrics Filtering: Filter by complexity, fan-in, fan-out
• Algorithm Integration: Run Magellan algorithms (reachable, dead-code, cycles)

Quick Start

use llmgrep::Backend;
use std::path::Path;

// Open a Magellan database
let db_path = Path::new(".magellan/llmgrep.db");
let backend = Backend::detect_and_open(db_path)?;

See the query module for search functions and options.

Modules

• algorithm - Magellan algorithm integration (reachable, dead-code, cycles)
• ast - AST node queries and context
• backend - Backend abstraction (SQLite, Geometric)
• error - Error types
• output - Response types and formatting
• query - Search functions and options
• safe_extraction - Safe UTF-8 extraction
