This plugin provides an user interface within CLion to easily use clang-tidy on your project's sources. Results will be displayed within an intuitive UI which allows to select and apply single changes to your project.

What is clang-tidy

clang-tidy is part of Clang, the C/C++/ObjectiveC compiler backend of LLVM.

When running clang-tidy, it performs a static code analysis to find some common issues and code style violations and provides fixes which can be applied to your code.

Some checks of clang-tidy, formerly known as clang-modernize, checks for code constructs, which can be converted into modern C++11 syntax. For example this includes:

  • converting iterator based or index based for loops into range based foreach loops
  • adding the override keyword to overridden functions in subclasses
  • replacing NULL macros with nullptr
  • replacing function arguments to match the pass-by-value idiom to gain advantage from new move semantics

To learn more about clang-tidy visit


  1. Download this plugin from IntelliJ plugin portal.
  2. Visit to download the latest version of llvm and clang or view instructions how to install them on your preferred linux distribution.
  3. In CLion open your settings and go to Other settings / clang-tidy and enter the full path to your clang-tidy executable.


  1. Before using clang-tidy, you should commit your current working directory into VCS or backup your project, if clang-tidy produces errors in your code.
  2. Right click on a single C/C++/ObjC file, opened editor or directory containing source files and select Refactor / clang-tidy.
  3. In the configuration dialog select the checks you want to apply and click OK to start clang-tidy.
  4. When finished, a list of all files containing issues will be displayed to you. Select the files you want to apply or click merge to view suggested fixes for a single selected file and apply them one by one.
