hub: git + hub = github

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

It can be 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 hub

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

Standalone via RubyGems

$ gem install 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.

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 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
