Utelua

Utelua is a name that appears in several informal discussions and project pages within the Lua ecosystem. There is no single, widely recognized project officially named utelua, and the term is used to describe a range of lightweight Lua-inspired scripting solutions rather than a single canonical implementation. As a result, information about utelua tends to vary by source and may refer to different embeddable runtimes that implement Lua-like syntax and APIs for constrained environments.

In general, projects associated with utelua aim to provide a compact, easy-to-embed interpreter suitable for microcontrollers, game engines, or other host applications that require scripting capabilities without the overhead of a full Lua distribution. Common characteristics include a small memory footprint, a C or C++ API for integration, and support for executing scripts at runtime with access to a limited host API. Some variants emphasize portability across operating systems; others focus on sandboxing or safety features to restrict script privileges.

Usage typically involves integrating the interpreter into a host program, initializing the runtime, loading script files or strings, and invoking functions defined in scripts from the host application. Depending on the source, features such as modules, coroutines, or a subset of Lua libraries may be available.
