Ruby Fleebie » Rubyize this : 4th edition

The 3rd edition marked the beginning of a new association between Rubyize this and RefactorMyCode. I did things in a rather clumsy manner, telling people about how cool RmC was while asking them to use pastie to submit their refactored version of the code. At that time I didn’t realize that RmC and Rubyize this were ready to work together.

Well, RmC is now the official way to submit your rubyized solution. With the trackback system in place, a link to your refactored code will appear here at the moment you hit the submit button on RmC.

Before diving into the 4th edition, I’d like to take a moment to talk about the results of the 3rd one. We started with something pretty ugly that turned onto something pretty awesome!. On a side note, I really liked how some participants transformed the already mean sentence into something even meaner. As an exemple, the test sentence was : « You truly are a moron, sir! » and someone changed it to « you truly are a stupid moron sir! ». Someone else add fuel to the fire by writing « you truly are a ’stupid’ moron, stupid sir! ». And finally, someone went as far as to write : « Stupid wabbit! Stupid, stupid, stupid! ». The situation was completely uncontrollable!

Enough said. Let’s get the ball rolling.

I have an array of insects and I want to be able to display on the screen the name, the iq and the annoyance factor of every members of a certain type. This “solution” works but has a ruby rating of 0.5/5. Moreover, it only works for butterflies… which feels rather incomplete and limiting. Remove stuff, add stuff and move stuff around. This dumb code must get smart and pretty!

class Bug
        attr_accessor :type
        attr_accessor :name
        attr_accessor :iq
        attr_accessor :annoyance_factor 
        
        def initialize(name,type,iq,annoyance_factor)
                if !type
                        @type="spider"
                else
                        @type=type
                end
                
                if !name
                        @name="unnamed"
                else
                        @name=name
                end          
                
                if !iq
                        @iq = 8
                else
                        @iq = iq
                end
                
                if !annoyance_factor
                        @annoyance_factor = 4
                else
                        @annoyance_factor = annoyance_factor
                end     
        end     
end
 
def keep_butterflies(bugs)
        butterflies = Array.new
        bugs.each do |bug|
                if bug.type == "butterfly"
                        butterflies.push(bug)
                end
        end     
        return butterflies
end
 
#create some bugs!
bugs = Array.new
bugs.push(Bug.new("ron","spider","4","2"))
bugs.push(Bug.new("don","spider","2","3"))
bugs.push(Bug.new("jake","ant","9","4"))
bugs.push(Bug.new("chris","ladybug","2","4"))
bugs.push(Bug.new("fred","cockchaffer","0","5"))
bugs.push(Bug.new("greg","butterfly","2","0"))
bugs.push(Bug.new("jason","butterfly","0","2"))
 
butterflies=keep_butterflies(bugs)
 
butterflies.each do |butterfly|
        puts "I am a butterfly and my name is #{butterfly.name}. I have an IQ of #{butterfly.iq} and an annoyance factor of #{butterfly.annoyance_factor}"
end

Give it a shot now!

Here’s my take. Bug as no logic in it so we can use the Struct class….

I’m wondering if I may have strayed away from refactoring and into code golf here……

Nothing too special here, just felt like posting something. I like others’ use of “method_missing”, but it just seemed a bit more work than was necessary….

Shortest complete solution. The struct solutions are good, but they don’t allow for default values….

Building on Mark Van Holstyn’s solution, keeping the ‘keep_spiders’ syntax and cleaner syntax for entering bugs….

Similar to above but the method missing on the Bug class…

Well, the repeated insults had to be introduced to have a failing test case

I agree. But whatever the reason, I had a good laugh watching everyone going mad with this sentence!

Some pretty crazy method_missing stuff… too “clever”, imo….

I was surprised the other solutions don’t have the class itself keeping track of instances….
