The equivalent of how I added namespace comments to Kaleidoscope source code

kaleidoscope-namespace-comments.sh

#!/usr/bin/env bash

cd "${KALEIDOSCOPE_DIR}"

cat > .clang-format <<EOF

BasedOnStyle: Google

Language: Cpp

FixNamespaceComments: true
KeepEmptyLinesAtTheStartOfBlocks: true
ReflowComments: false
EOF

fd '.*\.(h|cpp)$' src --print0 | xargs -0 clang-format -i
fd '.*\.(h|cpp)$' plugins --print0 | xargs -0 clang-format -i

git add --all && git commit -m "temporary clang-format"

perl -pi -e 's/(Fix.*:) true/$1 false/' .clang-format

fd '.*\.(h|cpp)$' src --print0 | xargs -0 clang-format -i
fd '.*\.(h|cpp)$' plugins --print0 | xargs -0 clang-format -i

git stash push -m "clang-format namespace comments"

git reset --hard HEAD^

git stash pop

# Manual review and fixup

Note: I did not actually run this script; I used magit in Emacs and edited the .clang-format file by hand. I've been using fd lately instead of find, and I was too lazy to convert it for this gist. And perl instead of sed because mac OS sed -i doesn't do what you'd want it to, and I can never remember the regex syntax for it. There may be errors.
