 KDevelop_ with the kdev-clang-tidy_ plugin, starting from version 5.1, performs
 static analysis using :program:`clang-tidy`. The plugin launches the
 :program:`clang-tidy` binary from the specified location and parses its
 output to provide a list of issues.

 QtCreator_ 4.6 integrates :program:`clang-tidy` warnings into the editor

 inspection in QtCreator, you need to create a copy of one of the presets and
