Commits often involve refactorings–behavior-preserving code modifications aiming at software design improvements. Refactoring operations pose a challenge to code reviewers, as distinguishing them from behavior-altering changes is often not a trivial task. Accordingly, research on automated refactoring detection tools has flourished over the past two decades, however, the majority of suggested tools is limited to Java projects. In this work, we present RefactoringMiner++, a refactoring detection tool based on the current state of the art: RefactoringMiner 3. While the latter focuses exclusively on Java, our tool is–to the best of our knowledge–the first publicly available refactoring detection tool for C++ projects. Being based on a refactoring detector for Java projects, our tool lacks support for many refactorings specific to C++. The most common language-independent refactoring types, however, are supported and even several language incompatibilities were reconciled. RefactoringMiner’s thorough evaluation provides confidence in our tool’s performance. In addition, we test RefactoringMiner++ on a small seeded dataset and demonstrate the tool’s capability in a short demo involving both refactorings and behavior-altering changes.
