Clazy now provides a plugin (on Unix ClazyClangTidy.so) that allows all its checks to run inside clang-tidy, unifying your static analysis workflow. You no longer need to run two separate tools — just configure Clazy’s checks through clang-tidy itself.
This change needed quite a few refactorings to make the existing Clazy codebase more adaptable. In total, changes were spread out to 9 different pull requests to gradually implement the needed changes. Besides implementing the functionality, the testsuite was also adapted to ensure Clazy’s clang-tidy provides proper results.
🔒 If the plugin isn’t in a standard library path, either add it to your LD_LIBRARY_PATH or provide an absolute path to the plugin file.
Unfortunately, Clang-Tidy needs to have Clazy checks enabled explicitly and does not have a concept of “levels” to group checks. While wildcards like clazy-* would also work, it enables all manual-level checks. Those have more false positives and can hurt performance.
Checks in Clang-Tidy can be disabled when prefixing them with “-“, whereas Clazy uses “no-“ prefixes. An example clang-tidy command to use all level0 checks, with overloaded-signal being disabled and the qt-keywords manual check being enabled:
