After some trial, I found the cause of the issue: the version of clang-format
installed via Homebrew.
The clang-format
installed through brew:
brew install clang-format
which is located at /opt/homebrew/bin/clang-format
.
For some reason, this version of clang-format
has problems with formatting both .c
and .h
files.
To resolve this, using clang-format
via LLVM instead:
brew install llvm
Then, update the clang-format
path to the newly installed version: /opt/homebrew/opt/llvm/bin/clang-format
This fixed the issue.
