Modules

Qore supports two kinds of modules:

• User Modules: modules written in Qore itself; Qore also comes with a set of user modules; see Module Overview for a list of user modules delivered with Qore with links to the module documentation
• Binary Modules: modules written in C++ using Qore's C++ API; there are many available from the qorelanguage github project; also from the Qore documentation, Module Overview has a list of binary modules, additionally see below for an overview of modules currently under active development
