Anyone out there build your own code analysis tools to do things like automated testing, query validation and so forth?
I've been trying to figure out ways of reading and refactoring some really old code while also determining how much change is actually necessary (ie. if I change this one thing, how far does the ripple of change carry me?)
I know there are fancy expensive tools out there for some other languages which will remain nameless, but what about for perl?
I suppose the short answer is, "Write better code, stupid!" But what if I'm stuck with other people's code, and a LOT of it!?
