Awesome Git Hooks

:anchor: Easy-to-use git hooks for automating tasks during git workflows.

Git hooks are custom scripts you can use to automate tasks which are triggered before or after a git command is executed. There are two groups of these hooks: client-side and server-side. Client-side hooks are triggered by operations such as committing and merging, while server-side hooks run on network operations such as receiving pushed commits. This repo contains helpful resources as well as a variety of git hook scripts that can be easily customized to serve different purposes.

commit-msg

• enforce-insert-issue-number - Make sure user did not delete the ISSUE-[#] string that was generated by prepare-commit-msg/insert-issue-number.hook.

post-checkout

• delete-pyc-files - Delete all .pyc files every time a new branch is checked out.
• new-branch-alert - Display a message when a new branch is checked out for the first time.

post-update

• update-server-info - Prepare a packed repository for use over dumb transports (e.g. http).

pre-commit

• format-code - Run command to format code and re-add any files modified after formatting.
• search-term - Fail commit if a specific term is found in the code.
• spell-check-md-files - Check files with .md extension for spelling errors.
• verify-name-and-email - Fail commit if user.name or user.email is incorrect.

prepare-commit-msg

• include-git-diff-name-status - Include the output of "git diff --name-status -r" into the message, just before the "git status" output.
• insert-issue-number - Insert issue number to beginning of the commit message.

pre-push

• prevent-bad-push - Prevent push of commits where the log message starts with "WIP" (work in progress).

pre-rebase

• prevent-rebase - Prevent topic branches that are already merged to 'next' branch from getting rebased, because allowing it would result in rebasing already published history.

query-watchman

• fsmonitor-watchman - Output to stdout all files that have been modified since a given time.

update

• update - Block unannotated tags from entering.

Quick Start

1. Pick a hook, any hook! Try the "verify-name-and-email" one if you're not sure where to start.
2. Navigate to your project's hooks folder (.git/hooks).
3. You should see a list of files already in there. Create a new file called the exact commit type that you want to use (eg: "commit-msg", "pre-rebase", "pre-commit", etc). Do not give it an extension.

4. Open your new file and paste the code from the hook you chose out of this repo (eg: verify-name-and-email.hook).
5. Save file. Done! Now the git hook will be triggered automatically.
