Manage the rubygems you need…

“Bundler makes sure Ruby applications run the same code on every machine”

From https://github.com/bundler/bundler

and their dependencies!

“and Bundler makes it easy to make sure that your application has the dependencies it needs to start up and run without errors.”

From http://bundler.io/

These are a few of

my favorite things!

What can Bundler do for you?

One developer, working on one project

One developer, working on many projects

If you are...

Best Practices

Create one bundle per theme

Add gems to the Gemfile, not the Gemfile.lock

Include ALL the gems you are using on the theme in the bundle

Best Practices

Specify the version of the gem if you know which one you need, otherwise you can let Bundler handle it

Update gems using Bundler, not manually

Once you have the bundle set up, use it!

Recommendations

State “require/bundler” in config.rb or set up a bash alias so that you don’t have to type “bundle exec…”

Use “chruby” to manage your system’s ruby version (https://github.com/postmodern/chruby)

Add the ruby version your gems use to your Gemfile

What does it look like?
