Import Statements

Import statements bring concepts and definitions from other Trilogy files into the current scope.

Syntax

import_statement: "import" (".")* IDENTIFIER ("." IDENTIFIER)* ("as" IDENTIFIER)?

Basic Import

Import a module by name:

import customer;

Relative Imports

Use dots to import from relative paths:

import .local_module;
import ..parent_module;

Nested Module Import

Import from nested module paths:

import models.customer;
import data.warehouse.sales;

Aliased Import

Use as to give the import a local alias. All concepts from the imported module will be namespaced under this alias:

import customer as c;
import models.order as ord;

After aliasing, reference concepts like c.id or ord.total.

Example

import customer as customer;
import order as order;
import std.money;
select
    customer.id,
    customer.name,
    sum(order.total) -> customer_total
;
