#symbolize ⇒ Object

A symbolized, underscored (i.e. reverse-camelized) representation of self.

Examples:

Hash.symbolize                     #=> :hash
ActiveRecord::Base.symbolize       #=> :"active_record/base"
"GetThisCamelOffMyCase".symbolize  #=> :get_this_camel_off_my_case

def symbolize
  self.to_s.underscore.to_sym
end

#tap {|_self| ... } ⇒ Object

Return self after yielding to the given block.

Useful for inline logging and diagnostics. Consider the following:

@items.map {|i| process(i) }.join(", ")

With tap, adding intermediate logging is simple:

@items.map {|i| process(i) }.tap {|obj| log obj.inspect }.join(", ")

– TODO Remove for Ruby 1.9

Yields:

  • (_self)
