ClangFormat usage tips
2020-09-19In this note I provide useful tips on how to use ClangFormat (somtimes called clang-format).
Run clang-format to check if a file is already formatted:
clang-format --dry-run -Werror foo.c || echo "not formatted!"
Run clang-format in parallel to check if files are formatted:
find . -iname "*.c" -or -iname "*.h" | xargs -P0 -I{} clang-format --dry-run -Werror {}
Run clang-format in parallel to reformat files:
find . -iname "*.c" -or -iname "*.h" | xargs -P0 -I{} clang-format -i {}
Useful command line options:
-Werror: causes clang-format to return non-zero exit status if any input file is not already formatted.--dry-run: don’t actually format, only check if files are formatted
