Project layout

A project is the folder that holds app.jadpo. Its layout is fixed, so you never decide where a file goes: its path follows from two facts, the business area it belongs to and what it declares.

The project's root holds a fixed set of files and folders. All application code lives in business areas, called domains, in folders under domains/, one level deep. Every domain holds the same fixed folders, each named after the kind of declaration it holds: entities/, actions/, queries/ and so on.

Each file holds one primary declaration, named after the file and written last in it, below everything it needs. Nothing else goes in the file unless the primary declaration uses it. Decided layout gives the whole layout, and Files and names the rules for each file.

A single file, or a folder with no app.jadpo above it, is checked as loose files: one implicit domain, with the layout rules off.
