Requirements Requirements

Familiarity with at least one other programming language. Programming experience. Optionally if you have familiarity with other scripting languages, that will make it easier to understand Lua.

Overview Overview

Lua is an easy to use scripting language that is used as an embedded plugin/extension language in different products. For example it is the embedded scripting language of network applications like nmap and wireshark, and can also be found as a scripting language in World of Warcraft, Orbiter and other games.

Lua can also be used as a standalone language. It is a lightweight, multi-paradigm programming language and therefore the course teaches various concepts that students will find useful in other areas of software engineering as well.

This course covers the basic programming constructs in Lua and contains a lot of programming exercises, so that newcomers can gain proficiency with the language, starting from scratch.

After completing the course the students will be able to write middle sized standalone Lua programs and script software products where Lua is the embedded language.
