In The Zone

Tonight was amazing. I was amazing. Well, at least I amazed myself.
Before I tell you what amazed me, let me fill you in on the background. I’ve been stalling on my latest project for a week now because I’ve had a mental roadblock on how to refactor it to a place where I can add the next feature Meg (my Customer) wants. I knew that the code was not in a place to add it, but just could not find the path to salvation.
When I got home from work, I had some time to kill, so I pulled out my powerbook and started refactoring. It was absolutely inspired. I just started extracting little methods. I renamed a class. I renamed some methods on the class. Just a handful of teensy little changes like that and all of the sudden my code made so much more sense. Simply renaming the class and extracting a couple of methods had revealed the design that I’d been looking for.
I went to dinner.
When we got back from dinner I set in to refactor more, and I’ve been refactoring all night. It’s been more of the same: teensy little changes. I’ll rename a method, or move it. I’ve removed three parameters from the constructor of an object that had no real reason to ask for them, and that made my code a lot prettier because I had to fish those parameters down everywhere I constructed the object.
I think that the code is finally in a state that I can add the feature Meg wants, but beyond that, it’s in a much better state than it was this morning.
It’s also worth noting that I’ve been doing this project test first, so I have a safety net under me as I make all these broad changes. I’ve got a good test- bed and that makes all of this possible.
