RefactoringMiner

RefactoringMiner is a Java library and API designed to automatically identify refactoring operations within code changes across multiple programming languages. It analyzes commits, pull requests, and commit ranges to detect over 100 refactoring types, from simple renames to complex structural changes. The tool also generates detailed Abstract Syntax Tree (AST) diffs, providing a deeper understanding of code evolution beyond traditional line-based diffs. ## Key Features - **Refactoring Detection** — Identifies 40+ classic refactorings from Fowler's catalog, 52 API-level changes, 8 migration patterns, and 5 test-specific refactorings. - **Multi-Language Support** — Works with Java, Python, and Kotlin codebases, with TypeScript support planned. - **AST Diff Generation** — Produces syntax-aware diffs at commit, pull request, and commit range levels. - **Visualization Tools** — Includes a Chrome extension for refactoring-aware commit reviews and interactive diff visualization in browsers. - **Advanced Diff Features** — Supports refactoring-aware tooltips, single-page views, embedded GitHub comments, and handling of code moved between files. ## Philosophy RefactoringMiner aims to make code evolution transparent and understandable by precisely tracking structural changes, helping developers and researchers analyze refactoring practices and improve code review processes.
