Hack your bundle for fun and profit (La Conf 2013)

Hack your bundle for fun and profit (La Conf 2013)

Bundler has turned out to be a super-usful tool for installing and managing dependencies, but it has hidden depths! This talk discusses some of the ways you can use Bundler and other tools together to boost your development productivity. I’ll walk through how to use the lesser-known but very handy commands like bundle gem, bundle open, and a few others. I’ll show you how to use Bundler to make sure you always run your app on the right version of Ruby, how to search through every gem in your Gemfile with a single command, and how to check for newer versions of the gems you use.
