Top Refactorings

This has been done before by another mentor, and it was fun. I’ve been watching my use of refactoring tools, and here is my top five list of seven most-used refactorings:

Rename
Introduce Variable
Extract Method
Inline variable
Inline method
Move Method
Change method signature

You might guess that I’m doing a fair amount of refactoring on legacy code.

I was suprised how much I’m using introduce/inline variable, but quite often I’m doing that to make a block of code ready for method extraction. Having broken out small methods, I sometimes find a larger method to extract, and then I inline the use of smaller methods. It’s sometimes hard to find the right level of generality.

I’d have trouble imagining that the first three weren’t everyone’s favorite refactorings.
