At a point in time, I worked on an Interactive Voice Response(IVR) application
using an IP PABX that uses Lua as one of it scripting languages. Since I had in
or the other worked and used the other languages that can be used in writing
scripts for the PABX, I decided to pick Lua programming language as my choice, for
writing scripts to be executed by the IP PABX.
Prior to that time, I had only heard of Lua being used as the scripting engine for
the popular game World of Warcraft, I knew I was about to learn a new language entirely,
so the first thing I did was to open my Firefox and do some background check about
Then I started the learning process, and along the line, I fell in love with it
because though it is interpreted, it
is extremely the fastest among scripting languages. And I have decided I
will continouslly blog about it.
Lua which means moon
in Portugese is a programming language developed by Roberto Ierusalimschy and Waldemar
Luiz in 1993 and was written with C language and in fact the authors intention then
was to use Lua to do what C could not do,
a kind of C extension. It was originally designed to be integrated with software
written in C and other conventional languages. It is a simple and small language
yet powerful because it can run on virtually any device.
Lua can be embedded in an application, for example I might have a portion of an
application that I want Lua to handle while C# handles the rest, it can stand alone
and also it can be used together with C language.
Now lets start programming with Lua
Lua has a syntax close to C language, so it wont be add from somebody with a C
background to quickly grasp. You can download Lua from http://www.lua.org/download.html
As its the custom in the programming world to always display Hello World, so we
which displays hello world on the console window.
My subsequent blog posts will always contain cheat sheets and Lua codes that I have
