Luacompatible

Luacompatible is an adjective used in software development to denote that a library, tool, or application is designed to work with the Lua scripting language, either by embedding Lua, providing Lua bindings, or extending functionality through Lua scripts. It indicates compatibility with Lua's C API, or with Lua binding frameworks, and compatibility across Lua versions.

The term can apply to libraries written in languages that expose or wrap the Lua C API, enabling loading into a Lua state or embedding a Lua interpreter into the host application. It may also refer to modules that provide Lua bindings for their features, enabling Lua scripts to call into host functionality.

Key criteria for Luacompatible projects include adherence to Lua's C API conventions, compatible data types between Lua and the host language, proper management of Lua state, robust error handling, and alignment with the targeted Lua version (for example Lua 5.3, 5.4, or LuaJIT). Some projects may claim Luacompatible across a range of versions, if they maintain broad compatibility.

Common use cases include game development, where Luacompatible engines allow scripts to control gameplay, UI, or AI, and application plug-ins or extensions, where Lua scripts automate tasks, customize behavior, or add features. The designation is typically cited to indicate practical interoperability rather than licensing or performance guarantees.

Limitations of the Luacompatible designation include that it does not guarantee performance, licensing terms, or feature parity. Some Lua features may be unavailable through bindings, and cross-platform or dependency issues may affect compatibility.
