It introduces you to the basics of Lua and helps you to understand the problems it solves. You will work with the basic language features, the libraries Lua provides, and powerful topics such as object-oriented programming. Every aspect of programming in Lua, variables, data types, functions, tables, arrays and objects, is covered in sufficient detail for you to get started. You will also find out about Lua's module system and how to interface with the operating system. After reading this book, you will be ready to use Lua as a programming language to write code that can interface with the operating system, automate tasks, make playable games, and much more. This book is a solid starting point for those who want to learn Lua in order to move onto other technologies such as Love2D or Roblox. A quick start guide is a focused, shorter title that provides a faster paced introduction to a technology. It is designed for people who don't need all the details at this point in their learning curve. This presentation has been streamlined to concentrate on the things you really need to know. What you will learn Understand the basics of programming the Lua language Understand how to use tables, the data structure that makes Lua so powerful Understand object-oriented programming in Lua using metatables Understand standard LUA libraries for math, file io, and more Manipulate string data using Lua Understand how to debug Lua applications quickly and effciently Understand how to embed Lua into applications with the Lua C API Who this book is for This book is for developers who want to get up and running with Lua. This book is ideal for programmers who want to learn to embed Lua in their own applications, as well as for beginner programmers who have never coded before.

Authored by Roberto Ierusalimschy, the chief architect of the language, this volume covers all aspects of Lua 5---from the basics to its API with C---explaining how to make good use of its features and giving numerous code examples. (Computer Books)

Learn to design and develop safe and reliable embedded systems Key Features Identify and overcome challenges in embedded environments Understand the steps required to increase the security of IoT solutions Build safety-critical and memory-safe parallel and distributed embedded systems Book Description Embedded systems are self-contained devices with a dedicated purpose. We come across a variety of fields of applications for embedded systems in industries such as automotive, telecommunications, healthcare and consumer electronics, just to name a few. Embedded Systems Architecture begins with a bird's eye view of embedded development and how it differs from the other systems that you may be familiar with. You will first be guided to set up an optimal development environment, then move on to software tools and methodologies to improve the work flow. You will explore the boot-up mechanisms and the memory management strategies typical of a real-time embedded system. Through the analysis of the programming interface of the reference microcontroller, you'll look at the implementation of the features and the device drivers. Next, you'll learn about the techniques used to reduce power consumption. Then you will be introduced to the technologies, protocols and security aspects related to integrating the system into IoT solutions. By the end of the book, you will have explored various aspects of embedded architecture, including task synchronization in a multi-threading environment, and the safety models adopted by modern real-time operating systems. What you will learn Participate in the design and definition phase of an embedded product Get to grips with writing code for ARM Cortex-M microcontrollers Build an embedded development lab and optimize the workflow Write memory-safe code Understand the architecture behind the communication interfaces Understand the design and development patterns for connected and distributed devices in the IoT Master multitask parallel execution patterns and real-time operating systems Who this book is for If you’re a software developer or designer wanting to learn about embedded programming, this is the book for you. You’ll also find this book useful if you’re a less experienced embedded programmer willing to expand your knowledge.

Lua is a small, fast, powerful, and embeddable scripting language. It is well-suited for use in video games, application scripting, embedded devices, and nearly anywhere else a scripting language is needed. This quick reference contains a wealth of knowledge on how to program in and embed Lua, whether it is Lua 5.4, 5.3, 5.2, or 5.1. It groups the language's features and C API in a convenient and easy-to-use manner, while clearly marking the differences between Lua versions. This book covers: * Lua syntax, expressions, and statements. * Metatables and metamethods. * Object-oriented programming with Lua. * Creating and working with Lua and C Modules. * Lua's standard library and its C API. * Collaborative multi-threading in Lua and C. * How to embed and use Lua within a host. * And much more.

This book is for students and professionals who are intrigued by the prospect of learning and using a powerful language that provides a rich infrastructure for creating programs. No programming knowledge is necessary to benefit from this book except for the section on Lua bindings, which requires some familiarity with the C programming language. A certain comfort level with command-line operations, text editing, and directory structures is assumed. You need surprisingly little in the way of computer resources to learn and use Lua. This book focuses on Windows and Unix-like (including Linux) systems, but any operating system that supports a command shell should be suitable. You'll need a text editor to prepare and save Lua scripts. If you choose to extend Lua with libraries written in a programming language like C, you'll need a suitable software development kit. Many of these kits are freely available on the Internet but, unlike Lua, they can consume prodigious amounts of disk space and memory.

This manual is the official definition of Lua 5.1. It covers Lua's syntax and semantics, the full API with C, and the standard libraries. Lua is an extension programming language designed to support general procedural programming with data description facilities. It also offers good support for object-oriented programming, functional programming, and data-driven programming. Lua is intended to be used as a powerful, light-weight scripting language for any program that needs one. Lua is implemented as a library, and is highly portable, being written in clean C (that is, in the common subset of ANSI C and C++). This printed version contains the full text of the eletronic version, available at http: //www.lua.org/manual/.
