Question

I have the following file structure:

|_controllers
| |___FooController.pm
|_models
| |___Foo.pm
|_utils
| |___BarUtils.pm
|_foobar.do

I want to know how can I import the modules between files, let say that I want to use Foo.pm on FooControllers.pm or use BarUtils.pm on foobar.do . When I have the files on the same directories I just do

use Foo;

But in this case I cannot figure out how to do it.

Answer 1

You need to make sure that:

• The parent directory (the one that contains controllers etc..) is in @INC

• The modules would then be named:

  use controllers::FooController;
  use models::Foo;
  

The exact rationale for how and why this works (as well as @INC details) can be found on SO:

• How is Perl's @INC constructed? (aka What are all the ways of affecting where Perl modules are searched for?)

• How does a Perl program know where to find the file containing Perl module it uses?
