Modules Overview

This page explains what modules are, why they matter, and introduces the available modules.

What are modules

Modules are a unit of encapsulation in KDB-X. They have access to their own local namespace that can contain internal and external functions and variables for the module, as opposed to designating a fixed global namespace as it is often done for pre-module libraries.

The modules can expose variables and functions using the export variable, which can then be imported by code with the use function and assigned to an arbitrary name. Modules can be written in q or using the C API.
