if_not_ni

[wtd]

code:

class ElseHandler     def otherwise(&blk)         blk.call     end end class Object     def otherwise(&blk)         self     end     def if_not_nil(&blk)         if self.is_a? NilClass             ElseHandler.new         elsif blk             yield self         end     end end

And now...

code:

doSomethingThatReturnsNil.if_not_nil { |v| v.doSomething }.otherwise { doSomethingElse }

Can replace:

code:

tmp = doSomethingThatReturnsNil if tmp     tmp.doSomething else    doSomethingElse end
