Combinatory method like tap, but able to return a different value?

Question

I\'m going through a phase of trying to avoid temporary variables and over-use of conditional where I can use a more fluid style of coding. I\'ve taken a great liking to us

Answer 1

I found a method in the Facets gem that might be what you were looking for: Kernel#ergo

So your original method:

def not_nice_method
  obj = something_complex(a, b, c)
  if a_predicate_check?
    obj.one_more_method_call
  else
    obj
  end
end

might end up looking something like this:

require 'facets/kernel/ergo'

def nice_method
  something_complex(a, b, c).ergo do |_| 
    a_predicate_check? ? _.one_more_method_call : _
  end
end
