Programmieren mit Perl ist die Übersetzung der 2. Auflage von Programming Perl, der anerkannten Perl-Bibel. Perl selbst ist die erste von Larry Wall geschaffene Legende, dieses Buch (überall liebevoll nur das "Kamel-Buch" genannt) ist die zweite. Gemeinsam mit anderen Perl-Experten lüftet Wall die vielen neuen Geheimnisse der Version 5 von Perl, liefert dabei gleichzeitig aber auch neue Einsichten in die alten und erprobten Features. Perl ist zur ungekrönten Königin der Programmiersprachen herangewachsen und wird zunehmend als die nützlichste Sprache angesehen, wenn es darum geht, eine Vielzahl von Aufgaben über viele Plattformen hinweg und so portabel wie möglich zu erledigen. Nicht mehr zufrieden damit, nur die Unix-Umgebung zu dominieren, zog Perl aus, nun auch noch die Web- Programmierung zu beherrschen. Programmieren mit Perl enthält unter anderem: Eine ausführliche Einführung in die Sprache und ihre Syntax; eine vollständige Referenz aller Perl-Funktionen, Perl-Operationen und Standard-Bibliotheksmodule; eine Erläuterung der Perl-Referenzen und komplexen Datenstrukturen; eine detaillierte Darstellung der objektorientierten Eigenschaften von Perl; weiterführende Themen wie Effizienz, Debugging, Aufrufoptionen, Sicherheit von Programmen, Interprozesskommunikation, Autoloading und vieles mehr.

Adopted as the undisputed Perl bible soon after the first edition appeared in 1991, Programming Perl is still the go-to guide for this highly practical language. Perl began life as a super-fueled text processing utility, but quickly evolved into a general purpose programming language that’s helped hundreds of thousands of programmers, system administrators, and enthusiasts, like you, get your job done. In this much-anticipated update to "the Camel," three renowned Perl authors cover the language up to its current version, Perl 5.14, with a preview of features in the upcoming 5.16. In a world where Unicode is increasingly essential for text processing, Perl offers the best and least painful support of any major language, smoothly integrating Unicode everywhere—including in Perl’s most popular feature: regular expressions. Important features covered by this update include: New keywords and syntax I/O layers and encodings New backslash escapes Unicode 6.0 Unicode grapheme clusters and properties Named captures in regexes Recursive and grammatical patterns Expanded coverage of CPAN Current best practices

Programming on the Web today can involve any of several technologies, but the Common Gateway Interface (CGI) has held its ground as the most mature method--and one of the most powerful ones--of providing dynamic web content. CGI is a generic interface for calling external programs to crunch numbers, query databases, generate customized graphics, or perform any other server-side task. There was a time when CGI was the only game in town for server-side programming; today, although we have ASP, PHP, Java servlets, and ColdFusion (among others), CGI continues to be the most ubiquitous server-side technology on the Web.CGI programs can be written in any programming language, but Perl is by far the most popular language for CGI. Initially developed over a decade ago for text processing, Perl has evolved into a powerful object-oriented language, while retaining its simplicity of use. CGI programmers appreciate Perl's text manipulation features and its CGI.pm module, which gives a well-integrated object-oriented interface to practically all CGI-related tasks. While other languages might be more elegant or more efficient, Perl is still considered the primary language for CGI.CGI Programming with Perl, Second Edition, offers a comprehensive explanation of using CGI to serve dynamic web content. Based on the best-selling CGI Programming on the World Wide Web, this edition has been completely rewritten to demonstrate current techniques available with the CGI.pm module and the latest versions of Perl. The book starts at the beginning, by explaining how CGI works, and then moves swiftly into the subtle details of developing CGI programs.Topics include: Incorporating JavaScript for form validation Controlling browser caching Making CGI scripts secure in Perl Working with databases Creating simple search engines Maintaining state between multiple sessions Generating graphics dynamically Improving performance of your CGI scripts

The Perl Journal (TPJ) did something most print journals aspire to, but few succeed. Within a remarkable short time, TPJ acquired a cult-following and became the voice of the Perl community. Every serious Perl programmer subscribed to it, and every notable Perl guru jumped at the opportunity to write for it. Back issues were swapped like trading cards. No longer in print format, TPJ remains the quintessential spirit of Perl--a publication for and by Perl programmers who see fun and beauty in an admittedly quirky little language.Games, Diversions, and Perl Culture is the third volume of The Best of the Perl Journal, compiled and re-edited by the original editor and publisher of The Perl Journal, Jon Orwant. In this series, we've taken the very best (and still relevant) articles published in TPJ over its 5 years of publication and immortalized them into three volumes.The 47 articles included in this volume are simply some of the best Perl articles ever written on the subjects of games, diversions, and the unique culture of this close-knit community, by some of the best Perl authors and coders. Games, Diversions & Perl Culture focuses on entertaining topics that make Perl users such fanatics about the language. You'll find all of the playful features TPJ offered over the years, including the Obfuscated Perl Contests, Perl Quiz Shows, humor articles, and renowned one-line recipes. The book also contains a panoply of quirky applications of Perl, including genetic algorithms, home automation, music programming, and an entire section on natural language processing.This anthology is an unmatched compendium of Perl lore.

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."

With its highly developed capacity to detect patterns in data, Perl has become one of the most popular languages for biological data analysis. But if you're a biologist with little or no programming experience, starting out in Perl can be a challenge. Many biologists have a difficult time learning how to apply the language to bioinformatics. The most popular Perl programming books are often too theoretical and too focused on computer science for a non-programming biologist who needs to solve very specific problems.Beginning Perl for Bioinformatics is designed to get you quickly over the Perl language barrier by approaching programming as an important new laboratory skill, revealing Perl programs and techniques that are immediately useful in the lab. Each chapter focuses on solving a particular bioinformatics problem or class of problems, starting with the simplest and increasing in complexity as the book progresses. Each chapter includes programming exercises and teaches bioinformatics by showing and modifying programs that deal with various kinds of practical biological problems. By the end of the book you'll have a solid understanding of Perl basics, a collection of programs for such tasks as parsing BLAST and GenBank, and the skills to take on more advanced bioinformatics programming. Some of the later chapters focus in greater detail on specific bioinformatics topics. This book is suitable for use as a classroom textbook, for self-study, and as a reference.The book covers: Programming basics and working with DNA sequences and strings Debugging your code Simulating gene mutations using random number generators Regular expressions and finding motifs in data Arrays, hashes, and relational databases Regular expressions and restriction maps Using Perl to parse PDB records, annotations in GenBank, and BLAST output
