LK is a scripting language originally developed for the National Renewable Energy Laboratory's System Advisor Model (SAM). LK is designed to be small, fast, and easily embedded in other applications, and provides a way for users to to extend an application's built-in functionality.

This repository contains a cross-platform standard library of function calls and core LK engine, which includes a lexical analyzer, parser, compiler, and virtual machine. It comprises roughly 7000 lines of ISO-standard C++ code, and is only dependent on the Standard C++ Library (STL), making LK extremely tight and portable to various platforms. LK also provides a C language API for writing extensions that can be dynamically loaded at runtime.

LK can utilize standard 8-bit ASCII strings via the built-in std::string class, or can be configured to utilize an std::string-compliant string class from an external library. In this way, Unicode text can be supported natively. For example, direct integration and linkage with the wxWidgets C++ GUI library string class is provided as an option.
