Marshalling data between C and Lua functions is also done using the stack. To call a Lua function, arguments are pushed onto the stack, and then the lua_call is used to call the actual function. When writing a C function to be directly called from Lua, the arguments are read from the stack. Here is an example of calling a Lua function from C:
SAS integrates Lua with PROC LUA as an alternative to its legacy macro language. [29] ScyllaDB uses Lua for user-defined functions, which let users deploy server-side scripts to perform data transforms such as aggregations, sums and averages. New versions of SciTE editor can be extended using Lua.

Lutro is a Lua game framework for libretro, a partial port of the LÖVE [40] API. ChaiLove follows a similar path by offering an implementation in ChaiScript, an embedded and cross-platform scripting language for C++ (C++14). [41] love.js is a port of LÖVE that aims to make it possible to run LÖVE games on the web via HTML5, WebGL, and ...
Function names are often of the form p.myFunctionName, where p is the table from the return p at the bottom of your program. The reason for this is that you can only access functions that are entries in this table from the original #invoke statement. Functions for local use within the program can have any name.
Allegro is a software library for video game development. [3] [4] [5] The functionality of the library includes support for basic 2D graphics, image manipulation, text output, audio output, MIDI music, input and timers, as well as additional routines for fixed-point and floating-point matrix arithmetic, Unicode strings, file system access, file manipulation, data files, and 3D graphics.
Few languages ever become sufficiently popular that they are used by more than a few people, but professional programmers may use dozens of languages in a career. Most programming languages are not standardized by an international (or national) standard, even widely used ones, such as Perl or Standard ML (despite the name).
Many software libraries are written in system programming languages such as C or C++. To use such libraries from another language, usually of higher-level, such as Java, Common Lisp, Scheme, Python, or Lua, a binding to the library must be created in that language, possibly requiring recompiling the language's code, depending on the amount of ...
