Re: Messing with %INC.

Well, this is certainly nicer than opening and reading a file full of code and then doing an eval on the code. Is there any way, though, that you could reread a configuration file that changes the behavior of the program and select among definitions of the routine?

Is this specifically a system designed to handle code plugins that are maintained separately and reload those while running? What you have is a fairly clean and straightforward way to do that I think. If those other files are not separately managed, though, I'd say write all your routines out and choose them dynamically through a reference rather than redefining them this way.

It's exactly that.

In that case, you may find mr_mischief's suggestion of using code references (such as anonymous subs in a hash) a much more flexible approach.

For example, the different plugins can reside in their own packages, and register themselves with the main program, instead of having all plugins be in the same package or the main program having to figure out where the plugin's functions are.

Reloading a file can be useful if you're reloading the same file repeatedly (e.g. after changes).

I do reload specific files, because they change.

Anonymous subs would make things more complicated. I posted the example out of the context of the actual application and this made explaining difficult. :-)
