These scripts are helpers for managing developer workflow when using git repositories hosted on GitHub. Install as a RubyGem and they can be run as standard git commands, eg: git about.

gem install mavenlink-git-scripts

cd /usr/local/bin && curl -L http://github.com/jrolfs/git-scripts/tarball/master | gunzip | tar xvf - --strip=2

git about shows settings set by git pair and git project

Configures git authors when pair programming.

$ git pair sp js
user.name=Josh Susser & Sam Pierson
user.email=pair+jsusser+sam@pivotallabs.com

Create a .pairs config file in project root or your home folder.

# .pairs - configuration for 'git pair'
pairs:
  # <initials>: <Firstname> <Lastname>[; <email-id>]
  eh: Edward Hieatt
  js: Josh Susser; jsusser
  sf: Serguei Filimonov; serguei
email:
  prefix: pair
  domain: pivotallabs.com
  no_solo_prefix: true
global: false  # Set to true for git-pair to change git configuration for all your projects

By default this affects the current project (.git/config). Use the --global option or add global: true to your .pairs file to set the global git configuration for all projects (~/.gitconfig).

Options are:

-g, --global                     Modify global git options instead of local
-v, --version                    Show Version
-h, --help                       Show this.

When you're done pairing, change git's configuration to use your personal details.

git pair <your-initials>

Makes a git commit as normal, but chooses one of the pair members randomly to get credit for the commit on github (by setting the author email to that member's email address). The author name on the commit will list all members of the pair, as usual.

If pair members have email addresses on different domains, you can specify them separately in the optional email_addresses: key in your .pairs file.

If pair members would like to sign commits with a GPG key, you can specifiy them in the optional gpg_keys: sections in your .pairs file.

pairs:
  jd: Jane Doe
  fb: Frances Bar
email_addresses:
  jd: jane@awesome.local
  fb: frances@foo.bar
gpg_keys:
  jd: A1B2C3D4
  fb: E5F6G7H8

RubyMine already supports pointing at a custom location for your git executable in the Preferences -> Version Control -> Git The trick then is that pair-commit doesn't encompass all git functionality, so you can't just point RubyMine directly at it, you need something in the middle that will use pair-commit if the first arg is commit, otherwise just pass through. Here's a ruby script to do just that:

#!/usr/bin/env ruby

exit_code = if ARGV[1] == "commit"
  system "git pair-commit #{ARGV[1..-1].join(" ")}"
else
  system "git #{ARGV.join(" ")}"
end

exit exit_code

Make sure it's executable.

git project pivots

This script sets the user account you will use to access repos hosted on github.com. It creates a symlink from id_github_current to id_github_pivotal<project>, which switches the SSH key you are currently using to access GitHub repos. Make sure you have the following lines in your .ssh/config file:

Host github.com
  User git
  IdentityFile /Users/pivotal/.ssh/id_github_current
