Modules

Modules are reusable units Oba code. Modules correspond to individual .oba files and can be used to break programs into smaller pieces.

All of the top-level function declarations and global variables defined in a module are “public” which means that other modules can import that module and read those symbols.

Imports

Modules are included into other modules using the import keyword:

import "system"

A module’s symbols can be accessed using the :: operator:

system::print("print from another module")

For now, Oba only supports importing core modules, which are built into the interpreter and made available to all programs. In a future release users will be able to write and import their own modules.

Core modules

Core modules are imported by name. e.g. import "system"

• system - Basic I/O and interaction with the host system.
• time - Timing routines.
