Better Tools in Your Clang Toolbox
summary
An open‑source Visual Studio extension Clang Power Tools brings clang‑tidy, clang‑format and LLVM compilation into MSVC workflows and a PowerShell CI script runs compilation and tidy in parallel with PCH support, extracting MSBuild settings automatically. Teams run selective modernization passes (range‑for, override, make_unique, use_auto) and write custom clang‑tidy checks using AST matchers and clang‑query. Adoption finds real bugs — missing virtual destructors, wrong enums, init order and dangling string_view — and exposes a buggy check (use‑using), but overall the tools scale and measurably modernize large codebases.
