Lua Tutorial

Lua is a small scripting language. It is a research team at the Pontifical Catholic University of Rio de Janeiro in Brazil, composed of Roberto Ierusalimschy, Waldemar Celes and Luiz Henrique de Figueiredo and developed in 1993. It is designed to be embedded in applications to provide them with flexible extensions and customization capabilities. Lua is written in standard C and can be compiled and run on almost all operating systems and platforms. Lua does not provide a powerful library, which is determined by its positioning. Therefore, Lua is not suitable as a language for developing stand-alone applications. Lua has a concurrent JIT project that provides just-in-time compilation capabilities on specific platforms.

Lua scripts can be easily called by C/C code, and can also call C/C functions in turn, which makes Lua widely used in applications. Not only as an extension script, but also as an ordinary configuration file, replacing XML, ini and other file formats, and is easier to understand and maintain.

Let’s experience the first Lua program!

The first Lua program

print("Hello World!")

Lua is written in standard C. The code is simple and beautiful, and can be compiled and run on almost all operating systems and platforms. A complete Lua interpreter only costs 200k. Among all current script engines, Lua is the fastest. All this determines that Lua is the best choice for embedded scripts.
