Module System

A Lumina project is structured like this

project-name
├── config.lm
└── src
    ├── main.lm
    ├── other_dir
    │   ├── file.lm
    │   └── lib.lm
    └── other_file.lm

When importing modules inside of Lumina source code, the relative filepath corresponds directly to the path in the use item.

So from main.lm the other modules would be imported as.

use other_dir:file
use other_dir
use other_file

lib.lm and main.lm are magic filenames which are put under the namespace of the folder they're in. So to import other_dir/lib.lm in main.lm then instead of use other_dir:lib, you'd use use other_dir

When importing a module, you can also import items from that module directly.

use other_file:file [Direction [Right, Down]]
//                   ^ Item
//                              ^ Members under Item

As opposed to using items through the module name.

fn down = file:Direction:Down
