How to split perl programm over multiple files

Question

How do I use functionality written in a different file, but not located in an @INC location, but relative to the main executable? I want to be able to distribute the entire directory and have it be executable everywhere (assuming third-party libraries are already installed).

Answer 1

You can use FindBin to get the location of your main executable and lib to add directories to your @INC that are based on your main directory.

A common example would be if your libraries were in a /lib directory below the directory that contains your main program.

use FindBin '$RealBin';
use lib "$RealBin/lib";

# You can then load your own modules from /lib
use My::Module;
