Modules

Modules group sets of functions and structures together in a namespace. Each source file is a separate module. Modules must be explicitly declared to be available for use. A module declaration is denoted by the keyword module followed by the module name.

module module_name

Modules can only be declared in the source root main.lx or in a module.lx file that is placed in a folder. Lexica will look for either a file or folder with the module name from the declaration location.

main.lx
module_name/
    module.lx

main.lx
module_name.lx

If both the file and folder exist then both sets of declarations in them will be processed.

Modules may also be declared inline inside a single file. The beginning of the module body is denoted by a colon.

module module_name:
    data Structure:
        field: Type,

External modules are not allowed to be declared inside a nested module.

module module_name:
    // This is NOT allowed.
    module external
