clang-tidy is a static analysis and linting tool for C and C++ developed as part of the LLVM project. It identifies potential programming errors, coding style violations and opportunities to improve source code using modern language features.
The application builds on Clang’s parsing and semantic analysis capabilities. Its checks cover categories such as bug-prone constructs, performance problems, readability issues, portability and compliance with established coding guidelines.
clang-tidy can also suggest or automatically apply corrections for many detected problems. Developers can select the checks appropriate to their project and integrate the tool into their existing build systems and continuous integration workflows.
This is free and open source software.
Key Features
- Static analysis of C and C++ source code using Clang’s compiler infrastructure.
- Detect potential bugs, suspicious constructs and incorrect API usage.
- Identify performance problems and unnecessary operations.
- Suggest modern C++ language features and programming practices.
- Readability checks covering naming conventions, code structure and maintainability.
- Support for coding guidelines including the C++ Core Guidelines and CERT.
- Run selected checks from Clang Static Analyzer.
- Modular architecture allowing developers to implement custom checks.
- Enable or disable checks through command-line options and configuration files.
- Project-specific configuration using .clang-tidy files.
- Automatic fixes for many supported diagnostics.
- Export suggested changes in YAML format for later application.
- Use compilation databases to obtain project build settings.
- Analyse selected files and filter diagnostics by source location.
- Integrate with editors, development environments and continuous integration systems.
- Treat selected warnings as errors to enforce project coding standards.
