Does anyone actually have a reusable-code system that survives long term?

I've spent years trying to organize reusable code. I've tried: ● snippet managers ● internal libraries ● private repositories ● documentation systems Everything works initially. Then projects evolve, code diverges, and suddenly there are multiple versions of the same utility everywhere. At this point I'm wondering if perfect organization simply isn't realistic. How are experienced developers handling this? submitted by /u/Unhappy-Pepper- [link] [留言]
