• Informed by Ruby Style Guide
• Class requirements
  • Spacing
    • 2 spaces per indent - no tabs
    • spaces in methods only if required to separate ideas
    • one space between methods
  • Case
    • snake_case variables
    • CamelCase classes
    • SCREAMING_SNAKE_CASE for constants
  • Methods
    • named what it returns not what it does (names, not get_names)
    • predicate methods end in a question mark (empty?)
    • dangerous methods end in an exclamation mark, where non-dangerous version exists (uniq and uniq!)
    • rarely more than 5 or 10 LOC
  • omit parenthesis, usually
  • prefer {...} over do...end for single line blocks
  • avoid perl style special variables ($0, $`, etc)
