Cannot find clang-format-diff

[Smeegol]

OS: macOS 11.5.2
clang-format version 12.0.1, installed by Homebrew
But, error while using it:

$ ./scripts/apply-format -i --staged
Cannot find clang-format-diff which should be shipped as part of the same
package where clang-format is.

Please find out where clang-format-diff is in your distro and report an issue
at https://github.com/barisione/clang-format-hooks/issues with details about
your operating system and setup.

You can also specify your own path for clang-format-diff by setting the
$CLANG_FORMAT_DIFF environment variable, for instance:

    CLANG_FORMAT_DIFF="python /.../clang-format-diff.py" \
        ./scripts/apply-format

Any idea where it's actually installed?

What do these say:

ls -l $(which -a clang-format)

and:

find /usr/local/ -name clang-format-diff*

You need to set the CLANG_FORMAT_DIFF environment variable to tell the script where to look. e.g.

export CLANG_FORMAT_DIFF="python3 /opt/homebrew/Cellar/clang-format/15.0.7/share/clang/clang-format-diff.py"
