Basic Ruby Syntax
- 1 min- Use :: only to reference constants(this includes classes and modules) and constructors (like Array() or Nokogiri::HTML()). Do not use :: for regular method invocation.
# bad
SomeClass::some_method
some_object::some_method
# good
SomeClass.some_method
some_object.some_method
SomeModule::SomeClass::SOME_CONST
SomeModule::SomeClass()
- Use def with parentheses when there are parameters. Omit the parentheses when the method doesn’t accept any parameters.
# bad
def some_method()
# body omitted
end
# good
def some_method
# body omitted
end
# bad
def some_method_with_parameters param1, param2
# body omitted
end
# good
def some_method_with_parameters(param1, param2)
# body omitted
end
- Methods that have “keyword” status in Ruby:
class Person
# bad
attr_reader(:name, :age)
# good
attr_reader :name, :age
# body omitted
end
- Do not use then for multi-line if/unless
# bad
if some_condition then
# body omitted
end
# good
if some_condition
# body omitted
end
