CircleCI Gem Version

Git Swap

Git Switch is now Git Swap. Due to git releasing a native switch command, the gem has been renamed.

Git Swap is a command line utility to easily swap between multiple git profiles. It uses a .gitswap YAML file to configure each profile (name, username, and email) and ssh key.

Prerequisites

This gem has been developed for, and only tested on, Mac OS.

Additionally, it requires git version 2.10+. Run git --version to check your currently install version. If you are using homebrew, you can install a newer version of git with brew upgrade git.

Installation

Install with Homebrew

The Homebrew tap installs the git swap utility globally, and solves the issue with the gem method, which limited the executable to the current gemset.

brew install randallreedjr/git_swap/git_swap

To verify successful installation:

git swap -v

Install with rubygems

This gem is not intended to be installed via a Gemfile. Instead, install it yourself:

gem install git_swap

If you use rvm, you can save yourself from some headaches by installing git_swap for all gemsets.

rvm @global do gem install git_swap

If transitioning from git_switch, version 0.5.0 or earlier, to git_swap version 1.0.0 or later, run this command to preserve your current configuration.

cp ~/.gitswitch ~/.gitswap && rm ~/.gitswitch

Configuration

To run the guided setup, use git swap --config.

You may also manually create or edit your configuration at ~/.gitswap. The config file is in YAML format. Here is an example.

personal:
  username: johnnyfive
  email: me@johnsmith.com
  name: Johnny Smith
  ssh: ~/.ssh/id_rsa
work:
  username: johnsmith
  email: john@defmethod.io
  name: John Smith
  ssh: ~/.ssh/defmethod_rsa

Note that the ssh key must already exist. See these instructions to generate a new SSH key.

The root keys can be any nickname you want. It should be memorable to make it easy to swap between profiles.

Usage

Git Swap follows the convention to create a custom git command. It can be invoked as follows, to either set your git profile locally (no flag) or globally (-g):

git swap personal
git swap personal -g

Note that in previous versions, invoking git swap would remove all identities from ssh-add, except the one specified. You can always readd them using ssh-add path/to/ssh.

Newer versions use git config to specify which ssh identity to use when running git commands.

Flags

  • Use -l or --list to list configured profiles
git swap -l
  • Use -v or --verbose to print more detailed output
git swap personal -v

Releasing

To release a new version of the gem:

  • Create a new release branch (releases/vx.y.z) off main.
  • Bump the version number in lib/git_swap/version.rb.
  • Rerun bundle to update Gemfile.lock
  • Open a pull request to the main branch
  • Merge pull request
  • Checkout main branch and create a tag
git tag vx.y.z
  • Push the tag to GitHub
git push --tags
  • Create a new GitHub release for the tag
  • Build the new version of the gem - gem build git_swap.gemspec
  • Push the gem to rubygems from the master branch; this is the only branch from which releases should be deployed - gem push git_swap-x.y.z.gem
