I've had a mac at work lately, and was amazed to see that Xcode would still find my latest project after I renamed its folder and moved it someplace else.

Now I understand that this is the result of a heavy infrastructure at work, but I was wondering if it would be possible to somehow come up with similar functionality for the rest of the Unix world ?

Mac OS X is in the Unix world. –  mouviciel Oct 14 '10 at 14:15
    
Indeed, edited. –  julien Oct 14 '10 at 14:54
    
Does it track changes no matter where you made the change? For example if you used mv /path/to/project /new/path/to/project would it still find it? Or are you moving/renaming in Xcode? Most IDEs will be able to trivially change/rename/move project files and still find them just fine. –  Falmarri Oct 14 '10 at 18:13
    
How did you move the project? Where did you move it to? I can certainly imagine that if you use Xcode to move it, it's a no-brainer. If Xcode uses some convention ("all projects are under ~/Projects") and you moved it around there, it could just look there (or even search all over your $HOME for stuff that looks like projects, today's machines have enough performance that you wouldn't necessarily notice). –  vonbrand Jan 31 '13 at 16:50

Well on Linux you could use inotify to track changes to your files. Inotify is in-kernel and has bindings to many different languages allowing you to quickly script such functionality if the app you are working with does not support inotify yet.

Sounds like it could be used to store ancient pathes to a file, and with a file-not-found-hook lookup the current path. Nice –  julien Oct 14 '10 at 16:26
