37. Smoke.exist?(path)
38. Get high.
39. Strategy Pattern
40. GitHub::RepoCreator handles repository creation
41. module GitHub RepoCreator = if Rails.fi? Fi::RepoCreator else Web::RepoCreator end end
42. module GitHub module Web class RepoCreator # implementation, lol end end end
43. module GitHub module Fi class RepoCreator < GitHub::Web::RepoCreator # implementation, lol end end end
44. module GitHub module Fi class RepoCreator < GitHub::Web::RepoCreator def setup_smoke # no-op end end end end
45. Provide a standardized API between products.
46. creator = GitHub::RepoCreator.new creator.setup
47. Feature flipping makes things less frightening.
48. if current_user.beta? beta_hotness end
