Captain Hook is a simple system to manage your git hooks.
The key concept is, that you have a central collection of your git hooks stored in ~/git-hooks . Rather than copying and/or manually combining these hooks in each of your repositories, Captain Hook lets you symlink & combine your scripts to produce sensible git hooks.
When git calls Captain Hook, it will search appropriate script directory(based on hook type) and try to execute every script forwarding all arguments from git. If any of the scripts fails, Captain Hook exits forwarding the return code of your script to git. Captain Hook only executes scripts up to the first script that fails.
For more concrete & in-depth explanation, check hookrun script.
Prerequisite: Our collection contains a script check-diff which can be used as a pre-commit hook(as specified by git).
mkdir new_project && cd new_projectgit inithook inithook add pre-commit check-diff
The hook is now setup, so that every time git runs its pre-commit hook, Captain Hook will call your script check-diff. The best part is, that your script is just a symlink, so modifying your hook will update all your repositories!
Just clone this repo to somewhere, fix CPTHOOK_DIR and HOOKS_DIR in hook script and make sure hook script is in your PATH.
cd ~git clone https://github.com/tomsik68/captain-hook.gitecho 'export PATH="PATH:$HOME/captain-hook"' >> ~/.bashrccd captain-hook && mkdir hooks
