Modules revisited

Every Spicy file specifies the module it declares.

module foo;

Other modules can be imported with the import keyword.

Typically, to refer to a type, function or variable in another module, it needs to be declared public.

# file: foo.spicy
module foo;

public global A = 47;
public const B = 11;
const C = 42;

# file: bar.spicy
module bar;

import foo;

print foo::A, foo::B;

# Rejected: 'foo::C' has not been declared public
# print foo::C;

Hint

Declaring something public makes it part of the external API of a module. This makes certain optimizations inapplicable (e.g., dead code removal).

Only declare something public if you intend it to be used by other modules.

Note

With spicy-1.11 (shipping with zeek-7) the rules around public are much more relaxed and public even closer maps onto "exposed C++ API". Above example use of a non-public const would be accepted.
