Ruby

• 2 SPACE INDENTATION
• generally follow community style guide: bbatsov/ruby-style-guide
• rubocop.yml template
• prefer rspec over test-unit

Lambdas and Procs

• See here: Procs
• The shorthand for creating Procs is Kernel.lambda BUT WITH SOME SLIGHT DIFFERENCES:
  • lambdas check the number of parameters passed when called (throws ArgumentError)
  • A return from a Proc returns from the enclosing method whereas lambdas return control to the caller
• In general, prefer lambda { } over Proc.new to avoid surprising behavior.

Framework specific

• Rails
• RSpec
