Fundamentals: Namespaces
A namespace is a named scope that contains a set of declarations.
To declare a namespace, use the namespace keyword.
namespace Foo;
When multiple files are in the same namespace, their declarations are merged together.
// file1.ara
namespace Foo;
const u8 MY_CONST = 1;
// file2.ara
namespace Foo;
const u8 MY_OTHER_CONST = 2;
// file3.ara
namespace Bar;
use Foo;
const u8 MY_CONST = Foo\MY_CONST;
const u8 MY_OTHER_CONST = Foo\MY_OTHER_CONST;
Root Namespace
In the absence of a namespace declaration, the declarations are in the root namespace.
const int MY_CONST = 1;
Nested Namespaces
Namespaces can be nested.
namespace Foo\Bar;
Importing
Namespaces can be imported using the use keyword.
use Foo;
const int MY_CONST = Foo\MY_CONST;
Aliasing
Namespaces can be aliased using the as keyword.
namespace Foo;
use Bar\Baz as Qux;
const int MY_CONST = Qux\MY_CONST;
Reserved Namespaces
The following namespaces are reserved, and cannot be used:
