hook (dont use)

I'm adding the following to the top of my REPO_ROOT/.git/hooks/pre-commit file:

for FILE in $(git diff --cached --name-only)
do
        clang-format -i $FILE
done 

The .clang-format file is placed in the REPO_ROOT. 

chmod a+x pre-commit

hook (use)

#!/usr/bin/env bash

for FILE in *

do

    if [[ "$FILE" =~ \.(c|h|cpp|cc)$ ]]

    then

        echo "processing $FILE"

        clang-format -i $FILE

    else

        echo "skip $FILE"

    fi

done
