Book Description:

With a worldwide community of users and more than a million dedicated programmers, Perl has proven to be the most effective language for the latest trends in computing and business.

Every programmer must keep up with the latest tools and techniques. This updated version of Advanced Perl Programming from O’Reilly gives you the essential knowledge of the modern Perl programmer. Whatever your current level of Perl expertise, this book will help you push your skills to the next level and become a more accomplished programmer.

O’Reilly’s most high-level Perl tutorial to date, Advanced Perl Programming, Second Edition teaches you all the complex techniques for production-ready Perl programs. This completely updated guide clearly explains concepts such as introspection, overriding built-ins, extending Perl’s object-oriented model, and testing your code for greater stability.

Book Description:

If you’re ready to get started with Perl 6, this is the book you want, whether you’re a programmer, system administrator, or web hacker. Perl 6 is a new language—a modern reinvention of Perl suitable for almost any task, from short fixes to complete web applications. This hands-on tutorial gets you started.

Author brian d foy (Mastering Perl) provides a sophisticated introduction to this new programming language. Each chapter in this guide contains exercises to help you practice what you learn as you learn it. Other books may teach you to program in Perl 6, but this book will turn you into a Perl 6 programmer.

Learn how to work with:

Numbers, strings, blocks, and positionals
Files and directories and input/output
Associatives, subroutines, classes, and roles
Junctions and sets
Regular expressions and built-in grammars
Concurrency features: Promises, supplies, and channels
Controlling external programs and other advanced features

Book Description:

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.
