Who This Book Is For This book is for developers who would like to learn the Perl programming language. A basic knowledge of programming is assumed. What You Will Learn Learn the background from which Perl 6 appeared and how it developed. How to use Rakudo to run your programs. Various Perl 6 built-in types and details about their behavior Understand how scalar variables, hash variables, and arrays work Create meta operators and hyper operators How classes work and how to build software based on the Object Oriented Paradigm How Perl 6 provides support for concurrency, functional programming, and reactive programming. In Detail Perl is a family of high-level, general-purpose, interpreted, dynamic programming languages consisting of Perl 5 and Perl 6. Perl 6 helps developers write concise and declarative code that is easy to maintain. This book is an end-to-end guide that will help non-Perl developers get to grips with the language and use it to solve real-world problems. Beginning with a brief introduction to Perl 6, the first module in the book will teach you how to write and execute basic programs. The second module delves into language constructs, where you will learn about the built-in data types, variables, operators, modules, subroutines, and so on available in Perl 6. Here the book also delves deeply into data manipulation (for example, strings and text files) and you will learn how to create safe and correct Perl 6 modules. You will learn to create software in Perl by following the Object Oriented Paradigm. The final module explains in detail the incredible concurrency support provided by Perl 6. Here you will also learn about regexes, functional programming, and reactive programming in Perl 6. By the end of the book, with the help of a number of examples that you can follow and immediately run, modify, and use in practice, you will be fully conversant with the benefits of Perl 6. Style and approach This book will take you through essential Perl 6 concepts so you can implement them immediately

Book excerpt: Internally, however, there are still kinks and stumbling blocks that developers need to sidestep, long-abandoned features maintained only for backward compatibility, misdirected phrasings that hinder more intuitive syntax structures, and a cacophony of modules that sometimes work well together, but occasionally don't. Perl 5 continues to have a strong following devoted to its development, but in the meantime, a core group of Perl developers has begun work on Perl 6, a complete rewrite of the Perl language. While Perl's creative philosophy and common-sense syntax are sure to remain in Perl 6, everything else in the language is being reexamined and re-created.

Available in PDF, EPUB and Kindle. Book excerpt: Write good regexes and parsers with the Perl 6 programming language. You’ll see how regexes are used for searching, parsing, and validation: in particular the grammar extension makes them uniquely suitable for parsing, the main focus of this book. Written by Perl 6 expert Moritz Lenz, a core contributor of Rakudo, Parsing with Perl 6 Regexes and Grammars starts from the very basics of regular expressions, and then explores how they integrate with regular Perl 6 code. Then follows a deeper exploration of how regexes work under the hood and a discussion of common techniques for constructing regexes and exploring the data under scrutiny. Later material goes beyond relatively simple formats to reusable named regexes and grammars, which permit code reuse in grammars, and shows how to write parsers for more involved data formats. Error reporting and case studies wrap up the topic. While regexes allow you to search for patterns in text and validate input, Perl 6 regexes advance that concept: you’ll see how they are easier to read, yet much more powerful, than the traditional "Perl-compatible regular expression". With improved reusability and backtracking control, you will be able to write complete parsers with the help of this book. What You'll Learn Discover the building blocks of Perl 6 regexes Handle regex mechanics and master useful regex techniques Extract data and work with patterns among these use cases Reuse named regexes and other grammars as components or templates Write full parsers, including advanced error reporting and data extraction Learn how to parse nested scopes and indention-based formats Who This Book Is For Those with at least some prior experience with Perl programming, but who may be new to Perl 6 as well as searching and parsing.

Available in PDF, EPUB and Kindle. Book excerpt: Among the many different approaches to "templating" with Perl--such as Embperl, Mason, HTML::Template, and hundreds of other lesser known systems--the Template Toolkit is widely recognized as one of the most versatile. Like other templating systems, the Template Toolkit allows programmers to embed Perl code and custom macros into HTML documents in order to create customized documents on the fly. But unlike the others, the Template Toolkit is as facile at producing HTML as it is at producing XML, PDF, or any other output format. And because it has its own simple templating language, templates can be written and edited by people who don't know Perl. In short, the Template Toolkit combines the best features of its competitors, with ease-of-use and flexibility, resulting in a technology that's fast, powerful and extensible, and ideally suited to the production and maintenance of web content and other dynamic document systems.In Perl Template Toolkit you'll find detailed coverage of this increasingly popular technology. Written by core members of the technology's development team, the book guides you through the entire process of installing, configuring, using, and extending the Template Toolkit. It begins with a fast-paced but thorough tutorial on building web content with the Template Toolkit, and then walks you through generating and using data files, particularly with XML. It also provides detailed information on the Template Toolkit's modules, libraries, and tools in addition to a complete reference manual.Topics in the book include: Getting started with the template toolkit The Template language Template directives Filters Plugins Extending the Template Toolkit Accessing databases XML Advanced static web page techniques Dynamic web content and web applications The only book to cover this important tool, Perl Template Toolkit is essential reading for any Perl programmer who wants to create dynamic web content that is remarkably easy to maintain. This book is your surefire guide to implementing this fast, flexible, and powerful templating system.

Available in PDF, EPUB and Kindle. Book excerpt: Many programmers would love to use Perl for projects that involve heavy lifting, but miss the many traditional algorithms that textbooks teach for other languages. Computer scientists have identified many techniques that a wide range of programs need, such as: Fuzzy pattern matching for text (identify misspellings!) Finding correlations in data Game-playing algorithms Predicting phenomena such as Web traffic Polynomial and spline fitting Using algorithms explained in this book, you too can carry out traditional programming tasks in a high-powered, efficient, easy-to-maintain manner with Perl.This book assumes a basic understanding of Perl syntax and functions, but not necessarily any background in computer science. The authors explain in a readable fashion the reasons for using various classic programming techniques, the kind of applications that use them, and -- most important -- how to code these algorithms in Perl.If you are an amateur programmer, this book will fill you in on the essential algorithms you need to solve problems like an expert. If you have already learned algorithms in other languages, you will be surprised at how much different (and often easier) it is to implement them in Perl. And yes, the book even has the obligatory fractal display program.There have been dozens of books on programming algorithms, some of them excellent, but never before has there been one that uses Perl.The authors include the editor of The Perl Journal and master librarian of CPAN; all are contributors to CPAN and have archived much of the code in this book there."This book was so exciting I lost sleep reading it."

Available in PDF, EPUB and Kindle. Book excerpt: Write Apps for Maximum Performance and Responsiveness “Threading and concurrency are as important in mobile as they are in large, distributed systems. This book does an excellent job of re-introducing us to the basic concepts and describing how to apply them to the Android framework. Even the most experienced Android developer should pick up at least a few tricks from these pages.” —Dave Smith, PE, Google Developer Expert for Android Mastering concurrency is critical to developing software with superior performance and responsiveness. This is especially true for Android, where interruptions are frequent and abrupt, and in order to be correct, programs must be aware of component and process lifecycles in addition to being thread safe. You need a deep, Android-specific understanding of concurrency—and Android Concurrency delivers it. This guide in Addison-Wesley’s Android Deep Dive series for experienced Android developers helps you leverage today’s multi-core processors and heavily cached architectures, as well as major improvements built into Android 5 (Lollipop). Top Android developer and consultant Blake Meike strips the magic and mystery from concurrent programming and presents intensely practical solutions for everything from inter-thread communication to network communication. Meike introduces a simple but powerful architectural framework you can use to address new issues whenever they arise, and offers expert guidance for debugging even highly complex concurrency issues. Android Concurrency combines in-depth knowledge, proven patterns and idioms, and world-class insights for avoiding performance-killing mistakes. For serious Android developers, it will be an indispensable resource. You will • Gain new clarity about what concurrency really is, and how concurrent processes work • Master best practices for writing concurrent code that’s more robust and less susceptible to weird, hard-to-diagnose errors • Review the Java concurrency mechanisms Android’s constructs are built upon • Shape an approach to concurrency that reflects the unique characteristics of the Android environment • Avoid widespread misconceptions that lead Android developers into trouble • Make the most of AsyncTask—but only when it’s the right tool for the job • Leverage the powerful, lightweight Looper/Handler framework to support scheduled, asynchronous tasks and execute many message types • Use the Android Service component to separate business logic from UI • Understand the differences between started and bound services and use them effectively for intra- and inter-process communication • Perform scheduled tasks, including tasks requiring polling and explicit scheduling • Track down problems via static analysis, annotations, and assertions
