Setup Git Hooks

First install llvm/clang tools on your operating system, then configure the repo:

$ cd esl
$ git config core.hooksPath ".githooks"

To ensure hook scripts will be executed properly, may require some extra setup on your system.

  target="/usr/bin/clang-format-diff.py"
  command -v "clang-format-diff.py" > /dev/null 2>&1 &&
    echo "clang-format-diff.py is already set" ||
    [[ -s "${src}" ]] &&
