GitHooks

Githooks provides a framework for creating standard pre-commit and commit-msg hooks for your git repository. These hooks run client side (not on a remote server), and can be used to validate your commits (actual deltas and commit messages), reducing the possibility of broken commits (or bad commit messages) making it into your repository.

Installation

gem install rabbitt-githooks
add rabbitt-githooks to the development group of your project's Gemfile
setup your project to use githooks:

cd /path/to/project
mkdir commit-hooks
githooks attach --path /path/to/commit-hooks

With the hooks installed, you can run the checks against your staged or unstaged deltas before you commit, or just commit your deltas and have the checks run automatically.

Creating Tests

Tests Path

All tests should be located under the path that was defined when attaching githooks to your project. In the following examples we'll assume a project root of /work/projects/railsapp and a hooks path of /work/projects/railsapp/.hooks.

Registration

All hooks must be registered via GitHooks::Hook.register <PHASE>, <BLOCK>

Main Testing Library with Tests (in execution order):
  Tests loaded from:

  Phase PreCommit:
      1: Standards
        1: Validate Ruby Syntax
          Limiter 1: :type -> [:modified, :added]
          Limiter 2: :path -> /^(app|lib)\/.+\.rb$/
        2: No Leading Spaces in Ruby files
          Limiter 1: :type -> [:modified, :added]
          Limiter 2: :path -> /^(app|lib)\/.+\.rb$/
        3: Validate CSS Syntax
          Limiter 1: :type -> [:modified, :added]
          Limiter 2: :path -> /^(app|lib)\/.+css$/
  Phase CommitMsg:
      1: Commit Message
        1: Message Length > 5 characters
        2: Verify no simple commit messages

Manually Running Tests

To run the pre-commit hook on unstaged deltas, run the following command:

$ cd /path/to/cms ; githooks exec --unstaged
