Summary

GitHooks provides a multi-hook framework for Git Hooks, along with a collection of scripts for the purposes of encouraging a commit policy, altering the project environment depending on the state of the repository, and implementing continuous integration workflows. The framework allows multi-script execution, you can use GitHooks to automate or optimize virtually any aspect of your development workflow.

Getting Started

Git Hooks are event-based scripts you can place in a hooks directory to trigger actions at certain points in git’s execution. When you run certain git commands, the software will run the associated script within the git repository. GitHooks extends on this by enabling the installation of any arbitrary number of hooks for a command.

Installation

You can install hooks in a git repository by two methods: unzipping then deleting, or manually copying in the scripts. Either option you will need to use the command line to setup your git repository, however it is recommended to use the unzip method as it is less likely to encounter mistakes (forgetting to set execution bit, missing a script, etc).

Unzip githooks

You can quickly install a set of hooks into the git repository by unzipping githooks.zip into the .git/hooks/ directory. To install all hooks and sub-hooks, you can do so with the following:

unzip githooks.zip -d .git/hooks/
chmod +x .git/hooks/*

You can then delete any hooks from the .git/hooks/ directory that you do not wish to use.

Manual Copying

To manually install a git hook, you will need to start by copying the hook into the .git/hooks/ directory. The git hook, also known as the entrypoint hook, is responsible for executing scripts in a sub-directory. If you wish to install the commit-msg hook, you can do the following:

cp commit-msg .git/hooks/commit-msg
mkdir -p .git/hooks/commit-msg.d/
chmod +x .git/hooks/commit-msg

After copying in the entrypoint hook, you will be able to copy hooks into a sub-directory named after the hook (e.g. commit-msg.d/). These hooks will be run by the entrypoint hook, commit-msg. To add a hook, you can do so with the following:

cp 001-my-githook.sh .git/hooks/commit-msg.d/

This will install the hook 001-my-githook.sh into the commit-msg.d/ directory. When the entrypoint commit-msg is executed, it will call any scripts in the commit-msg.d/ directory. The entrypoint hook can be of the form of any supported git hook (applypatch-msg, commit-msg, post-update, pre-applypatch, pre-commit, etc).
