When should I use C instead of pure Lua?

Integration with C is recommended for performance-bottleneck tasks, accessing hardware-level APIs, or when you need to embed a lightweight scripting language into an existing C/C++ application.

How does the virtual stack facilitate C-Lua integration?

The stack serves as the communication bridge between C and Lua; C code pushes values onto the stack to provide arguments to Lua, and pops values to receive results, ensuring memory safety and type control.

What are Lua userdata types in C?

Userdata allows developers to store arbitrary C data (like structs or pointers) inside Lua values, which can then be managed and manipulated via C-defined metatables for object-oriented behavior.

What is the primary purpose of the Lua-C API?

The Lua-C API is a set of functions that allows C code to interact with the Lua virtual machine, enabling the creation of high-performance native extensions or the embedding of Lua as a scripting engine.

Developer Tools

Integrates Lua scripting with native C code using the Lua-C API for high-performance extensions and application embedding.

About

This skill provides expert guidance on the Lua-C API, enabling developers to bridge the gap between high-level scripting and low-level performance. It covers essential patterns for virtual stack manipulation, the creation of native C modules, and the implementation of custom userdata types with metatables. Whether you are embedding Lua into a game engine or building high-performance native libraries for a Lua environment, this skill ensures robust memory management, efficient bidirectional communication, and optimal error handling across the language boundary.
