Ruby assign context to lambda?

Question

Is it possible not to assign context to lambda?

For example:

class Rule
  def get_rule
    return lambda {puts name}
  end
end

class Person
  attr_         


        

Answer 1

A bit late to party, but here's an alternate way of doing this by explicitly passing the context to the rule.

class Rule
  def get_rule
    return lambda{|context| puts context.name}
  end
end

class Person
  attr_accessor :name
  def init_rule
    @name = "ruby"
    Rule.new.get_rule.call(self)
  end
end

Person.new.init_rule
#=> ruby
