Tailored static tooling using Clang: Clazy
summary
A Clang plugin that adds Qt-specific static checks and auto-fix "fixit" patches to catch real misuses (unsafe childEvent casts, unnecessary QString UTF-8→UTF-16 allocations, bad pass-by-value vs const-ref) and integrate into CI. It uses the LLVM/Clang APIs, reads compile_commands.json, runs per-project or inside Qt Creator and KDevelop, groups checks by false-positive risk (levels 0–3), is ~22,000 lines on GitHub and actively applies fixes that work on real code.
