git-flow-hooks

Some useful hooks for git-flow (AVH Edition).

What does it do?

• Prevent direct commits to the master branch.
• Prevent merge marker commits.
• Automatically bump versions when starting a release or hotfix. Versions are generated, written to file and committed.
• Automatically specify tag messages.

Usage

Install

Clone this repository somewhere on your disk.

git clone git@github.com:jaspernbrouwer/git-flow-hooks.git

Whenever your read /path/to/git-flow-hooks, replace it with the actual path to your clone/working copy.

OS X

OS X doesn't support sort -V, which is used to sort git tags by version number, which in turn is needed to correctly bump versions.

On OS X you can install coreutils (using MacPorts or Homebrew), after which gsort -V can be used. If it's located at /opt/local/bin/gsort or /usr/local/bin/gsort we will pick it up automatically. Otherwise we fall back to /usr/bin/sort.

Optionally you can use the configuration option VERSION_SORT to point to a different command.

Activate

Initialize git-flow.

git flow init

It will ask you some questions, the last will be Hooks and filters directory?, which you can answer with /path/to/git-flow-hooks.

If you've already initialized git-flow, you can still set/change the path manually.

git config gitflow.path.hooks /path/to/git-flow-hooks

Prevention hooks

The hooks that prevent direct commits to the master branch, and prevent merge marker commits, are pre-commit hooks.

These only function if they're located in the .git/hooks directory of your working copy. In other words, after activating like described above, these hooks still won't kick in.

I see 2 options:

1. In stead of activating like described above, remove the .git/hooks directory and make it a symbolic link (ln -s /path/to/git-flow-hooks .git/hooks).
2. Create a symbolic link to the pre-commit file (ln -s /path/to/git-flow-hooks/pre-commit .git/hooks/pre-commit).

If you know a better way to use the pre-commit hooks, please let me know by opening an issue!

Update

Simply pull any updates from origin.

cd /path/to/git-flow-hooks
git pull

That's it, all your repositories that have git-flow initialized and use /path/to/git-flow-hooks as hooks and filters directory will be up-to-date.

Configuration

This is completely optional!

Global

Copy the file /path/to/git-flow-hooks/modules/git-flow-hooks-config.sh.dist to /path/to/git-flow-hooks/git-flow-hooks-config.sh (hooks directory) and change whatever you like.

Local

Copy the file /path/to/git-flow-hooks/modules/git-flow-hooks-config.sh.dist to .git/git-flow-hooks-config.sh (repository root) and change whatever you like.

Any settings in the local configuration file will override settings in the global one. So remove settings you don't want to override.

git-flow

git-flow (AVH Edition) has some useful configuration options too. See its wiki for a complete list. Or you can type git flow <command> [<subcommand>] --help.

Starting releases and hotfixes

If git flow release start and git flow hotfix start are run without a version, the version will be bumped automatically. Releases will be bumped at the minor level (1.2.3 becomes 1.3.0), hotfixes at the patch level (1.2.3 becomes 1.2.4). The hooks will look at the git tags to find the version to bump. If no tags are found, it looks for the version-file. If that isn't found, it assumes the current version is 0.0.0.

Alternatively you may use patch, minor and major as version. A bump of that level will take place.

If the commands are run with version, that version will be used (no bumping).

Bump messages

git-flow-hooks bumps the version in a commit with the message "Bump version to %version%".

If you want to use a different message, you can change it in the git-flow-hooks configuration.

Automatic tag messages

If you want tag messages to be automated (you won't be bothered with your editor to specify it), use the following configuration options:

git config gitflow.hotfix.finish.message "Hotfix %tag%"
git config gitflow.release.finish.message "Release %tag%"

If you like, you can change the tag-placeholder (%tag% in the example above) in the git-flow-hooks configuration.

Plugins

We want to create a plugin-like structure where users can add functionality in a more uniform way. Unfortunately, that would take some time and testing to implement.

While it's in progress, you can try to use the following forks:

• Send notifications with changelog to Slack and HipChat (diff)
