hub: git + hub = github
=======================

`hub` is a command line utility which adds GitHub knowledge to `git`.

It can used on its own or as a `git` wrapper.

Normal:

    $ hub clone rtomayko/tilt

    Expands to:
    $ git clone git://github.com/rtomayko/tilt.git

Wrapping `git`:

    $ git clone rack/rack

    Expands to:
    $ git clone git://github.com/rack/rack.git

hub requires you have `git` installed and in your `$PATH`. It also
requires Ruby 1.8.6+ or Ruby 1.9.1+. No other libraries necessary.


Install
-------

### Standalone

`hub` is most easily installed as a standalone script:

    curl http://defunkt.io/hub/standalone -sLo ~/bin/hub &&
    chmod 755 ~/bin/hub

Assuming `~/bin/` is in your `$PATH`, you're ready to roll:

    $ hub version
    git version 1.7.0.4
    hub version 1.1.0

### Homebrew

    $ brew install hub
    $ which hub
    /usr/local/bin/hub
    $ hub version
    ...

### RubyGems

Though not recommended, `hub` can also be installed as a RubyGem:

    $ gem install git-hub

Yes, the gem name is "git-hub".

(It's not recommended for casual use because of the RubyGems startup
time. See [this gist][speed] for information.)

### Standalone via RubyGems

Yes, the gem name is still "git-hub":

    $ gem install git-hub
    $ hub hub standalone > ~/bin/hub && chmod 755 ~/bin/hub

This installs a standalone version which doesn't require RubyGems to
run.

### Source

You can also install from source:

    $ git clone git://github.com/defunkt/hub.git
    $ cd hub
    $ rake install prefix=/usr/local

### Help! It's Slow!

Is your prompt slow? It may be hub.

1. Check that it's **not** installed using RubyGems.
2. Check that RUBYOPT isn't loading anything shady:

       $ echo $RUBYOPT

3. Check that your system Ruby is speedy:

       $ time /usr/bin/env ruby -e0

If #3 is slow, it may be your [GC settings][gc].


Aliasing
--------

`hub` works best when it wraps `git`. This is not dangerous - your
normal git commands should all work. hub merely adds some sugar.

Typing `hub alias <shell>` will display alias instructions for
your shell. `hub alias` alone will show the known shells.

For example:

    $ hub alias bash
    Run this in your shell to start using `hub` as `git`:
      alias git=hub

You should place this command in your `.bash_profile` or other startup
script to ensure runs on login.

The alias command can also be eval'd directly using the `-s` flag:

    $ eval `hub alias -s bash`


Commands
--------

Assuming you've aliased `hub` to `git` the following commands now have
superpowers:

GitHub Login
------------

To get the most out of `hub`, you'll want to ensure your GitHub login
is stored locally in your Git config or environment variables.

To test it run this:

    $ git config --global github.user

If you see nothing, you need to set the config setting:

    $ git config --global github.user YOUR_USER

For commands that require write access to GitHub (such as `fork`), you'll want to
setup "github.token" as well. See [local GitHub config guide][2] for more information.

Want to use environment variables instead of a local gitconfig?

* `GITHUB_USER`  - If set, this will be used instead of the `github.user` config
                   value to determine your GitHub username.
* `GITHUB_TOKEN` - If set, this will be used instead of the `github.token` config
                   value to determine your GitHub API token.

Configuration
-------------

If you prefer `http://` clones to `git://` clones, you can set the
`hub.http-clone` option to true using `git-config`.

For example:

    $ git clone defunkt/repl
    < git clone >
    $ git config --global --bool hub.http-clone true
    $ git clone defunkt/repl
    < http clone >

Or you can enter this manually into your `~/.gitconfig` file:

    $ cat ~/.gitconfig
    [hub]
      http-clone = yes


Prior Art
---------

These projects also aim to either improve git or make interacting with
GitHub simpler:

* [eg](http://www.gnome.org/~newren/eg/)
* [github-gem](http://github.com/defunkt/github-gem)
* [gh](http://github.com/visionmedia/gh)

------------

Once you've made your great commits:

1. [Fork][0] hub
2. Create a topic branch - `git checkout -b my_branch`
3. Push to your branch - `git push origin my_branch`
4. Create an [Issue][1] with a link to your branch
5. That's it!
