Keep your code sane with clang-tidy
summary
Shows that clang-tidy is a clang-based lint framework that runs checks and often applies fixes automatically, e.g. adding override, converting loops to range-for and replacing long iterator types with auto. Demonstrates clang-format sorting includes and reformatting, and YouCompleteMe providing accurate completions even inside macros. Claims about scale: about half of Google’s codebase is converted to use override. Notes that fixes handle the 90–99% cases but need code review for tricky side effects, shadowing, or platform-specific iterator patterns.
