clazy

Provides over 50 Qt-specific checks, such as detecting unnecessary QString allocations and misused signal-slot connections, which generic tools like clang-tidy miss, as listed in the README.

Many checks include automatic code refactoring capabilities, like fixing old-style connect syntax or adding missing QStringRef, directly from compiler warnings without manual intervention.

Checks are organized into levels 0-2 and manual, allowing granular control to start with safe checks and gradually enable more aggressive ones, reducing false positives.

Can run over JSON compilation databases without building the project via clazy-standalone, enabling integration into CI pipelines or pre-commit hooks for static analysis only.
