Programming Perl
- Used Book in Good Condition
- Christiansen, Tom (Author)
- English (Publication Language)
by Tom Christiansen, brian d foy, Larry Wall and Jon Orwant remains the reference guide for this handy language. Perl was born as a super-powered word processing utility, but it quickly became a general-purpose programming language that has helped hundreds of thousands of programmers, sysadmins, and enthusiasts like you get their work done.
In this long-awaited Perl programming books to “The Camel”, three renowned Perl authors cover the language up to its current version, Perl 5.14, with a preview of the upcoming 5.16 features. In a world where Unicode is increasingly essential for word processing, Perl offers the best and least painful support of all major languages, easily integrating Unicode everywhere, even in Perl’s most popular feature: Regular Expressions. Important features covered by this Camel book update include:
New keywords and syntax
I / O layers and encodings
The new backslash escapes
Unicode 6.0
Clusters and Unicode Grapheme Properties
Named captures in regular expressions
Recursive and grammatical models
Wide CPAN coverage
Current good practices
Intermediate Perl: Beyond The Basics of Learning Perl

- English (Publication Language)
- 394 Pages - 09/11/2012 (Publication Date) - O'Reilly Media (Publisher)
by Randal L. Schwartz, brian d foy, Tom Phoenix. This book picks up right where Learning Perl leaves off. With Intermediate Perl, you’ll graduate from short scripts to much larger programs, using features that make Perl a general-purpose language. This gentle but thorough guide introduces you to modules, complex data structures, and object-oriented programming.
Each chapter is small enough to be read in just an hour or two, ending with exercises to help you practice what you’ve learned. If you’re familiar with the material in Learning Perl and have the ambition to go further, Intermediate Perl will teach you most of the core Perl language concepts you need for writing robust programs on any platform.
Topics include:
Packages and namespaces
References and scoping, including regular expression references
Manipulating complex data structures
Object-oriented programming
Writing and using modules
Testing Perl code
Contributing to CPAN
Just like Learning Perl, material in this book closely follows the popular introductory Perl course the authors have taught since 1991. This second edition covers recent changes to the language up to version 5.14.
Parsing with Perl 6 Regexes and Grammars: A Recursive Descent into Parsing
- Lenz, Moritz (Author)
- English (Publication Language)
- 215 Pages - 12/11/2017 (Publication Date) - Apress (Publisher)
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 Grammarsstarts 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
