similarity-ts-core

Core library for TypeScript/JavaScript code similarity detection using AST-based comparison.

Features

• Extract functions from TypeScript/JavaScript code
• Compare function similarity using Tree Structured Edit Distance (TSED)
• Fast similarity detection with bloom filter pre-filtering
• Support for various function types (regular functions, arrow functions, methods)
• Configurable similarity thresholds

Usage

use similarity_core::{extract_functions, compare_functions, TSEDOptions};

// Extract functions from code
let functions = extract_functions("example.ts", source_code)?;

// Compare two functions
let options = TSEDOptions::default();
let similarity = compare_functions(&func1, &func2, source1, source2, &options)?;
