You can run `git hooks --uninstall` at any time to revert to your previous hooks. (These are usually the default hooks, which do nothing.) + +Run `git hooks --installglobal` to force any new git repository or any git repository you clone to have a reminder to install git hooks. (It can't be on by default for security reasons.) + + +Overview +======== + +Hooks are powerful and useful. Some common hooks include: + +- Spell check the commit message. +- Verify that the code builds. +- Verify that any new files contain a copyright with the current year in it. + +Hooks can be very project-specific such as: + +- Verify that the project still builds +- Verify that autotests matching the modified files still pass with no errors. +- Pre-populate the commit message with a "standard" format. +- Verify that any new code follows a "standard" coding style. + +Or very person-specific hooks, such as: + +- Don't allow a `push` to a remote repository after 1AM, in case I break something and will be asleep. +- Don't allow a commit between 9-5 for projects in `~/personal/`, as I shouldn't be working on them during work hours. + +For more details about the different hooks available to you, check out: + + http://www.kernel.org/pub/software/scm/git/docs/githooks.html + + + +Locations +========= + +git-hooks provide a way to manage and share your hooks using three locations: + + - **User hooks**, installed in `~/.git_hooks/` + - **Project hooks**, installed in `.git/git_hooks/` in a project. + - **Global hooks**, specified with the `hooks.global` configuration option. + +The `contrib/` directory includes a number of useful hooks, and can be set by doing the following: + + git config --global hooks.global $PWD/contrib/ + +You can even specify _multiple_ directories for your global hooks! Simply separate each path with spaces. + + +Creating hooks +============== + +To keep things organized, git-hooks looks for scripts in **sub-directories** named after the git hook name. For example, this project has the following `pre-commit` script in the following location: + + git_hooks/pre-commit/bsd + +When `git hooks` is run without arguments, it lists all hooks installed on your system. It will run the hooks with the `--about` argument to generate the description shown. + +Check out the hooks in `contrib/` for some examples. + |
