format

To apply clang-format to only changed lines in a C++ git diff, pipe the filtered git diff output into clang-format-diff.py using the -p1 and -i flags to edit files in place.

Formatting entire C++ files creates unnecessary diff noise during code reviews by rewriting unchanged lines. Incremental styling formats only reported git diff lines against HEAD to keep reviews focused on actual changes.

Yes, you can use clang-format-diff.py for incremental styling in OpenHarmony graphic_2d repositories by targeting graphic_2d/**/*.cpp and graphic_2d/**/*.h files with the repo-provided clang-format binary.

The best way to format C++ headers and sources without rewriting whole files is using clang-format-diff.py to isolate and format only the specific lines reported by your current git diff against HEAD.

Yes, you need to run incremental formatting commands from the OpenHarmony repo root to correctly execute the prebuilts clang-format binary and apply changes to your graphic_2d C++ files.

This incremental formatting approach is scoped specifically to graphic_2d/**/*.cpp and graphic_2d/**/*.h files within OpenHarmony repositories, targeting incremental formatting workflows during code reviews.
