Pipe an object through a block only if condition is true. Like the pipe which simply yields self.

conditional_pipe.rb

class Object
  def conditional_pipe(condition, &block)
    condition ? yield(self) : self
  end
  
  def true_tap(&block)
    self && yield(self)
    self
  end

  def false_tap(&block)
    self || yield(self)
    self
  end
end

"foobar".conditional_pipe(true) { |s| s.sub(/foo/, 'baz') }
#=> "bazbar"

"foobar".conditional_pipe(false) { |s| s.sub(/foo/, 'baz') }
#=> "foobar"

true.false_tap { |v| puts v }
#=> true

true.true_tap { |v| puts v }
# true
#=> true
