Parallel clang-tidy runner
==========================
Runs clang-tidy over all files in a compilation database. Requires clang-tidy
and clang-apply-replacements in $PATH.
Example invocations.
- Run clang-tidy on all files in the current working directory with a default
set of checks and show warnings in the cpp files and all project headers.
run-clang-tidy.py $PWD
- Fix all header guards.
run-clang-tidy.py -fix -checks=-*,llvm-header-guard
- Fix all header guards included from clang-tidy and header guards
for clang-tidy headers.
run-clang-tidy.py -fix -checks=-*,llvm-header-guard extra/clang-tidy \
-header-filter=extra/clang-tidy
