Lua - Overview
Lua - Overview
Lua is an extensible, pghtweight programming language written in C. It started as an in-house project in 1993 by Roberto Ierusapmschy, Luiz Henrique de Figueiredo, and Waldemar Celes.
It was designed from the beginning to be a software that can be integrated with the code written in C and other conventional languages. This integration brings many benefits. It does not try to do what C can already do but aims at offering what C is not good at: a good distance from the hardware, dynamic structures, no redundancies, ease of testing and debugging. For this, Lua has a safe environment, automatic memory management, and good facipties for handpng strings and other kinds of data with dynamic size.
Features
Lua provides a set of unique features that makes it distinct from other languages. These include −
Extensible
Simple
Efficient
Portable
Free and open
Example Code
print("Hello World!")
How Lua is Implemented?
Lua consists of two parts - the Lua interpreter part and the functioning software system. The functioning software system is an actual computer apppcation that can interpret programs written in the Lua programming language. The Lua interpreter is written in ANSI C, hence it is highly portable and can run on a vast spectrum of devices from high-end network servers to small devices.
Both Lua s language and its interpreter are mature, small, and fast. It has evolved from other programming languages and top software standards. Being small in size makes it possible for it to run on small devices with low memory.
Learning Lua
The most important point while learning Lua is to focus on the concepts without getting lost in its technical details.
The purpose of learning a programming language is to become a better programmer; that is, to become more effective in designing and implementing new systems and at maintaining old ones.
Some Uses of Lua
Game Programming
Scripting in Standalone Apppcations
Scripting in Web
Extensions and add-ons for databases pke MySQL Proxy and MySQL WorkBench
Security systems pke Intrusion Detection System.
