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.

24. Rails 4 sneak preview (well… DHH does this)
25. gives you a binary that you can run from cron bundle binstubs
26. no more cd in cronjobs /myapp/bin/rake foo
27. if your Ruby location is known, check it in /myapp/bin/rake foo
28. creates a Gemfile for you bundle init
29. bundle git locals
30. bundle git locals use git checkouts directly
31. bundle git locals changes apply instantly
32. bundle git locals commits update lock file
33. bundle config local.rack ~/sw/rack
34. enforce ruby versions ruby "1.9.3"
35. sets Heroku ruby version ruby "1.9.3"
36. bundle won’t load on wrong versions ruby "1.9.3"
37. literal dependency graph bundle viz
39. load your gems, then open IRB bundle console
40. create a new gem named NAME bundle gem NAME
41. gemspec, directories, release tasks, all there bundle gem NAME
42. tasks update when bundler updates bundle gem NAME
43. go forth and bundle
