Instance Method Details

#bind_with_indifference(obj) ⇒ Object Also known as: bind

Allows an unbound method to be bound to any object, instead of only those of the same class. Goes with original #bind method first, and if that fails, meta_def’s using #to_proc

def bind_with_indifference(obj)
  bind_without_indifference(obj) rescue class << obj; self end.class_eval(to_s(:ruby))
end

#name ⇒ Object

Simple string name. Taken from Pat Maddox’s with_context

def name
  @name ||= to_s.split("#").last.delete(">")
end

#to_proc ⇒ Object

eval’s and memoizes the output of Ruby2Ruby’s #to_ruby method

def to_proc
  @to_proc ||= eval(to_ruby)
end

#to_s_with_ruby(opt = nil) ⇒ Object Also known as: to_s

This is sort of ugly, but it does allow us to bind methods that take block arguments (you can’t use block arguments with blocks).
