Module: Jade::ModuleLoader::ModuleName

Extended by:
ModuleName
Included in:
ModuleName
Defined in:
lib/jade/module_loader/module_name.rb

Overview

A module is keyed by the name its file implies — imports resolve Shop.Cart to shop/cart.jd and back. The wrapper takes the declared name while every type reference inside takes the file's, so a mismatch emits Ruby referring to a constant that was never defined.
