git-flow
========
A collection of Git extensions to provide high-level repository operations
for Vincent Driessen's [branching model](http://nvie.com/git-model "original
blog post").


Installing git-flow
-------------------

### Mac OS
If you're on a Mac and use [homebrew](http://github.com/mxcl/homebrew), it's simple:

    $ brew install git-flow

If you're on a Mac and use [MacPorts](http://macports.org/), it's simple:

    $ port install git-flow

### Linux, etc.
Another easy way to install git-flow is using Rick Osborne's excellent git-flow
installer, which can be run using the following command:

	$ wget -q -O - https://github.com/nvie/gitflow/raw/develop/contrib/gitflow-installer.sh | sudo sh

### Windows
#### Using Cygwin
For Windows users who wish to use the automated install, it is suggested that you install [Cygwin](http://www.cygwin.com/)
first to install tools like `git`, `util-linux` and `wget` (with those three being packages that can be selected
during installation). Then simply run this command from a Cygwin shell:

	$ wget -q -O - https://github.com/nvie/gitflow/raw/develop/contrib/gitflow-installer.sh | sh

#### Using msysgit
This is much like the manual installation below, but there are additional steps required to install some extra tools that
are not distributed with [msysgit](http://code.google.com/p/msysgit/).

After cloning the git-flow sources from Github, also fetch the submodules:

	$ git submodule init
	$ git submodule update

Copy git-flow's relevant files to your msysgit installation directory:

	$ mkdir /usr/local/bin
	$ cp git-flow* gitflow* /usr/local/bin/
	$ cp shFlags/src/shflags /usr/local/bin/gitflow-shFlags

Next up we need to borrow a couple of binaries from [Cygwin](http://www.cygwin.com/). If you don't have Cygwin installed, please 
install it including the `util-linux` package. Apart from `util-linux`'s dependencies, no other packages are required. When you
finished installation, copy the following files using msysgit's _Git Bash_. We assume the Cygwin's default installation path in C:\cygwin.

	$ cd /c/cygwin/
	$ cp bin/getopt.exe /usr/local/bin/
	$ cp bin/cyggcc_s-1.dll /usr/local/bin/
	$ cp bin/cygiconv-2.dll /usr/local/bin/
	$ cp bin/cygintl-8.dll /usr/local/bin/
	$ cp bin/cygwin1.dll /usr/local/bin/

After copying the files above, you can safely uninstall your Cygwin installation by deleting the C:\cygwin directory.

### Manual installation
If you prefer a manual installation, please use the following instructions.
After downloading the sources from Github, also fetch the submodules:

	$ git submodule init
	$ git submodule update

Then, you can install `git-flow`, using:

	$ sudo make install

By default, git-flow will be installed in /usr/local. To change the prefix
where git-flow will be installed, simply specify it explicitly, using:

	$ sudo make prefix=/opt/local install

Or simply point your `PATH` environment variable to your git-flow checkout
directory.

*Installation note:*  
git-flow depends on the availability of the command line utility `getopt`,
which may not be available in your Unix/Linux environment.  Please use your
favorite package manager to install `getopt`.  For Cygwin, install the
`util-linux` package to get `getopt`.  If you use `apt-get` as your install
manager, the package name is `opt`.


Integration with your shell
---------------------------
For those who use the [Bash](http://www.gnu.org/software/bash/) or
[ZSH](http://www.zsh.org) shell, please check out the excellent work on the
[git-flow-completion](http://github.com/bobthecow/git-flow-completion) project
by [bobthecow](http://github.com/bobthecow). It offers tab-completion for all
git-flow subcommands and branch names.

For Windows users, [msysgit](http://code.google.com/p/msysgit/) is a good
starting place for installing git.

Typical usage:
--------------
For the best introduction to get started to `git flow`, please read Jeff
Kreeftmeijer's blog post:

### Initialization

To initialize a new repo with the basic branch structure, use:
  
		git flow init
  
This will then interactively prompt you with some questions on which branches
you would like to use as development and production branches, and how you
would like your prefixes be named. You may simply press Return on any of
those questions to accept the (sane) default suggestions.


### Creating feature/release/hotfix/support branches

* To list/start/finish feature branches, use:
  
  		git flow feature
  		git flow feature start <name> [<base>]
  		git flow feature finish <name>
  
  For feature branches, the `<base>` arg must be a commit on `develop`.

* To list/start/finish release branches, use:
  
  		git flow release
  		git flow release start <release> [<base>]
  		git flow release finish <release>
  
  For release branches, the `<base>` arg must be a commit on `develop`.
  
* To list/start/finish hotfix branches, use:
  
  		git flow hotfix
  		git flow hotfix start <release> [<base>]
  		git flow hotfix finish <release>
  
  For hotfix branches, the `<base>` arg must be a commit on `master`.

* To list/start support branches, use:
  
  		git flow support
  		git flow support start <release> <base>
  
  For support branches, the `<base>` arg must be a commit on `master`.


Showing your appreciation
=========================
A few people already requested it, so now it's here: a Flattr button.

Of course, the best way to show your appreciation for the original
[blog post](http://nvie.com/git-model) or the git-flow tool itself remains
contributing to the community.  If you'd like to show your appreciation in
another way, however, consider Flattr'ing me:
