Best ruby idiom for “nil or zero”

Question

I am looking for a concise way to check a value to see if it is nil or zero. Currently I am doing something like:

if (!val || val == 0)
  # Is nil or zero
e         


        

Answer 1

My solution also use Refinements, minus the conditionals.

module Nothingness
  refine Numeric do
    alias_method :nothing?, :zero?
  end

  refine NilClass do
    alias_method :nothing?, :nil?
  end
end

using Nothingness

if val.nothing?
  # Do something
end
