Use clazy to avoid Qt API pitfalls
Write good Qt code. Avoid the use of problematic Qt APIs.
While Qt prides itself on APIs that are consistent and simple to use - there are pitfalls. Parts of an API might turn out to be dangerous in practice or they may yield sub-optimal performance. clazy is a static code analysis tool built on to off the llcm/clang compiler infrastructure. It will issues warnings for Qt specific issues. See https://github.com/KDE/clazy for details and a list of the kind of warnings reported by clazy.
Either QtCreator >= 4.6, standalone or upstream clang (note that xcode-clang and android-clang do not work)
Very minimal (Qt Creator), small when already using upstream clang, potentially high if a project needs to be ported to upstream llvm/clang first.
All projects using C++ Qt.
- Clazy implements several warnings levels. The higher levels can produce false positives.
Usage via Qt Creator is probably the easiest way to get started. Integration into a CI system is probably best done via the standalone version of clazy in combination with a compilation database.
