Make friends local and global Git hooks

How to make local hooks work when you have set Git core.hooksPath

If core.hooksPath is set in Git local .git/hooks won't be triggered.

I'm using husky quite often and I need global hooks at the same time. That was a pain for a while. Today I found a solution: I call my local hooks from the global hooks.

Instruction

Let's assume we have such setup in our .gitconfig:

[core]
  hooksPath = /path/to/home/dir/.config/git/hooks

I declare a function in my shell:

ch() {
  HOOK="$HOME/.config/git/hooks/$1"
  if [[ -f "$HOOK" ]]
  then
    echo "\n\nif [[ -f \"\$PWD/.git/hooks/$1\" ]]; then\n  /bin/bash \"\$PWD/.git/hooks/$1\"\nfi" >> "$HOOK"
  else
    touch "$HOOK"
    echo "#\!/bin/bash\n\nif [[ -f \"\$PWD/.git/hooks/$1\" ]]; then\n  /bin/bash \"\$PWD/.git/hooks/$1\"\nfi" >> "$HOOK"
    chmod +x "$HOOK"
  fi
}

This function will create a hook file if it is not existed and append given code if the file already exist:

if [[ -f "$PWD/.git/hooks/hook-name" ]]; then
  /bin/bash "$PWD/.git/hooks/hook-name"
fi

Then we call this function for all possible hooks:

ch applypatch-msg
ch commit-msg
ch post-applypatch
ch post-checkout
ch post-commit
ch post-merge
ch post-rewrite
ch post-update
ch pre-applypatch
ch pre-auto-gc
ch pre-commit
ch pre-merge-commit
ch pre-push
ch pre-rebase
ch prepare-commit-msg
ch push-to-checkout
ch sendemail-validate 

That's it! Now your global hooks will check if local hook is presented and if so, it executes it.
