syntax.expected_declaration: Expected a declaration

Expected a declaration.

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

example

Count = Int

jadpo checkcheck failed: 1 error, 1 file

error Count doesn't start a declaration

--> main.jadpo:1:1

  |1 | Count = Int  | ^^^^^ expected a declaration

reason: A file holds declarations, such as type, function, action, query and entity, each starting a line.
next: Start the declaration with type: type Count = ... (agent)

A top-level var is this error too, and its next: points to constant, because at the top of a file a fixed value is a constant (area 3, Constants):

example

type VatRate = Decimal {    scale: 4}var vat_rate: VatRate = 0.2000

jadpo checkcheck failed: 1 error, 1 file

error var doesn't start a declaration

--> main.jadpo:5:1

  |5 | var vat_rate: VatRate = 0.2000  | ^^^ expected a declaration

reason: var names a value inside a body; at the top of a file a fixed value is a constant.
next: Write constant vat_rate: VatRate = 0.2000 (agent)
