Easily set/switch your current git user info for a git repo .git/config or your global ~/.gitconfig file.
This gem should come in handy if you have work and personal repositories. It also might help with switching between users while pair programming.
Would you rather type “git config user.email 'firstname.lastname@example.org'”, etc. or type “gitswitch switch work”? If you answered the latter, check out this gem.
# gem install gitswitch
First, establish a default ~/.gitswitch file using the git info you already have in your ~/.gitconfig file
# gitswitch init Gitswitch users file ~/.gitswitch not found. Would you like to create one? (y/n): y Adding your global .gitconfig user info to the "default" tag... Current git user information: Name: Joe Alba E-mail: email@example.com
Now, add a new git user tag
# gitswitch add Enter a tag to describe this git user entry: work E-mail address: firstname.lastname@example.org Name (ENTER to use "Joe Alba"): Joseph M. Alba
Set specific user info to your current git repository by updating .git/config
# gitswitch switch work # Update .git/config with your 'work' git user info Switching git user to "work" tag for the current repository (Joseph M. Alba <email@example.com>). # gitswitch switch # User info from your 'default' tag is used if you don't specify a tag Switching git user to "default" tag for the current repository (Joe Alba <firstname.lastname@example.org>).
List all the gitswitch user tags/info you have stored
# gitswitch list Current git user options -- default: Name: Joe Alba E-mail: email@example.com work: Name: Joseph M. Alba E-mail: firstname.lastname@example.org
Update a current entry. [TAG] parameter is optional. If omitted, you'll see a list.
# gitswitch update [TAG]
Delete a current entry. [TAG] parameter is optional. If omitted, you'll see a list.
# gitswitch delete [TAG]
Update your global .git user instead of your current repository
# gitswitch global work
Show your current git user info. If you are in a git repo directory, it will show you the info associated with the current repository. Outside a repo (or if you use the –global option), it will show you the info from your global .git config.
# gitswitch info
I initially wrote the gem using optparse and used the '-r' style params to keep the commands as short as possible. Now, I've decided to lean toward a rake-style descriptive method of passing commands – which meshes well with the way Thor likes to do things. But the old command line options still work fine in case you got used to it.
I've learned a few things, taken some inspiration from David Copeland's “Build Awesome Command-Line Applications in Ruby” book, and stolen the idea of making everything a class method from Hashrocket's hitch gem.
In Ruby 1.9, command line argument strings get frozen, which makes gsub! unhappy. I wasn't on 1.9 two years ago, and my tests are far too incomplete for Travis CI to catch this bug. But alas, it is now fixed.
I've made the first steps toward returning reasonable exit status codes. A failed git command will not yet throw a proper exit code.
