Next I read the official Programming in Lua book. In Part 1 you'll learn how to install Lua.

README.md Learning Lua. This repository contains notes I have created for my series of instructional videos on learning Lua. While used for my personal programming. This FAQ does not aim to help you to learn to program or even how to program in Lua. The best book to learn Lua is Programming in Lua by Roberto Ierusalimschy. Users who are relatively new to programming. Users of previous versions of Lua who want to learn. All things are discussed in terms of Lua and C in the tutorial.
Lua Basic Syntax. Let us start creating our first Lua program! First Lua Program.
Interactive Mode Programming. Lua provides a mode called interactive mode. In this mode, you can type in instructions one after the other and get instant results. This can be invoked in the shell by using the lua - i or just the lua command. Once you type in this, press Enter and the interactive mode will be started as shown below. When the script is finished, the interpreter is no longer active.
Let us write a simple Lua program. All Lua files will have extension . So put the following source code in a test. Below is the modified test. The first line is ignored by the interpreter if it starts with # sign.
Now, try to run this program as follows . For example, the following Lua statement consists of three tokens . An identifier starts with a letter 'A to Z' or 'a to z' or an underscore '. Lua is a case sensitive programming language. Thus Manpower and manpower are two different identifiers in Lua. Here are some examples of the acceptable identifiers . These reserved words may not be used as constants or variables or any other identifier names.
Whitespace in Lua. A line containing only whitespace, possibly with a comment, is known as a blank line, and a Lua interpreter totally ignores it. Whitespace is the term used in Lua to describe blanks, tabs, newline characters and comments. Whitespace separates one part of a statement from another and enables the interpreter to identify where one element in a statement, such as int ends, and the next element begins. Therefore, in the following statement .
On the other hand, in the following statement.
