goエンジニア向けgitのpre-commitとpre-pushファイルのオススメ

commit時にはgo fmt、　push時にはgo vetが走るようにしてます。

.git/hooks/pre-push

linterr="$(go vet ./... 2>&1 )"
if [ -n "$linterr" ] ; then
    echo "go vet error:"
    echo $linterr
    exit 1
fi
echo "finish go vet"

branch="$(git symbolic-ref HEAD 2>/dev/null)" || \
       "$(git describe --contains --all HEAD)"

if [ "${branch##refs/heads/}" = "main" ]; then
    echo "do not push to main"
    exit 1
fi

.git/hooks/pre-commit

before_diff_bytes=`git diff | wc -c`
diff_files=(`git diff --name-only HEAD ./`)

for diff_file in "${diff_files[@]}"
do
    if [[ $diff_file =~ \.go$ ]]; then
        gofmt -w $diff_file
    fi
done

after_diff_bytes=`git diff | wc -c`

diff_bytes=`expr $after_diff_bytes \- $before_diff_bytes`
if [[ $diff_bytes > 0 ]] ; then
    echo "\033[0;31m Check golang code format! \033[0;39m"
    exit 1
fi

if test "`git symbolic-ref HEAD | sed -e 's:^refs/heads/::'`" = main; then
        echo "cannot commit on main branch."
        exit 1
fi
