import.unneeded

On this page

A file imports a name it already sees without a use line, such as a built-in or something its test subject declares.

Area 1, Project layout and modules; not declinable; the next step is usually the agent's.

Why Jadpo refuses it

A use line tells a reader where a name lives. Some names need no such line, because where they live is already plain: built-in types and the standard library, what the file declares itself, what a test file's subject declares, and the file's own domain. An import of one of them says nothing, and suggests the name lives somewhere it doesn't.

What it looks like

domains/menu/actions/stock_item.jadpo:

example
use shared/types { Stock }/// A loaf's stock before any choices.function loaf_stock() -> Stock {    return 250}action stock_item() -> Stock {    return loaf_stock()}

domains/menu/actions/stock_item.test.jadpo, its test file:

example
use menu/actions { loaf_stock }test "a loaf has 250 in stock" {    assert loaf_stock() == 250}
jadpo checkcheck failed: 1 error, 4 files

error loaf_stock is declared in this test's subject

--> domains/menu/actions/stock_item.test.jadpo:1:20

  |1 | use menu/actions { loaf_stock }  |                    ^^^^^^^^^^ needs no import
reason
A test file sees everything its subject declares without importing it, and loaf_stock is in stock_item.jadpo.

(agent) at the end of the next: line means your coding agent can make the fix itself.

How to fix it

If the name is one the file already sees, remove the line. domains/menu/actions/stock_item.test.jadpo becomes:

example
test "a loaf has 250 in stock" {    assert loaf_stock() == 250}

The test calls loaf_stock directly, as it already could. Anything else it uses still comes in on a use line.
