As far as I understand it, XP discourages assuming something is going to be
needed until you actually get to that point where it is needed. Also
according to my understanding, that includes abstracting code to be more
general for reuse, until there is duplication, and then it can be
refactored.
So, what about reuse across projects? That'd be duplication, but not within
the same project.
I've put about 30 hours into a part of this project I'm working on that I
really think could be reused, which is why I'm curious about this. Surely
reuse across projects can save a lot of time.
So how do you handle this, when you're working on a new project, and there's
a part that is very similar to something in another project? How do you know
when to abstract it for better reuse?
