instance_exec(*args, &block) click to toggle source

Evaluate the block with the given arguments within the context of this object, so self is set to the method receiver.

From Mauricio’s eigenclass.org/hiki/bounded+space+instance_exec

This version has been borrowed from Rails for compatibility sake.

# File lib/qed/core_ext.rb, line 19
def instance_exec(*args, &block)
  begin
    old_critical, Thread.critical = Thread.critical, true
    n = 0
    n += 1 while respond_to?(method_name = "__instance_exec#{n}")
    InstanceExecMethods.module_eval { define_method(method_name, &block) }
  ensure
    Thread.critical = old_critical
  end

  begin
    send(method_name, *args)
  ensure
    InstanceExecMethods.module_eval { remove_method(method_name) } rescue nil
  end
end
must_return(value) click to toggle source

This is used by the ‘#=>` notation.

# File lib/qed/core_ext.rb, line 40
def must_return(value)
  assert(self == value, "#{self.inspect} #=> #{value.inspect}")
end
