Making Easy Things Easy and Hard Things Possible
If you're just getting started with Perl, this is the book you want-whether you're a programmer, system administrator, or web hacker. Nicknamed "the Llama" by two generations of users, this bestseller closely follows the popular introductory Perl course taught by the authors since 1991. This 6th edition more » covers recent changes to the language up to version 5.14.
Perl is suitable for almost any task on almost any platform, from short fixes to complete web applications. Learning Perl teaches you the basics and shows you how to write programs up to 128 lines long-roughly the size of 90% of the Perl programs in use today. Each chapter includes exercises to help you practice what you've just learned. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer. « less

Updated for Perl 5.14, the 5th more » edition provides a summary of Perl syntax rules and a complete list of operators, built-in functions, and other features. « less
Detailed Solutions in Eight Programming Languages
Regular Expressions for Perl, Ruby, PHP, Python, C, Java and .NET
Understand Your Data and Be More Productive
Regular expressions are an extremely powerful tool for manipulating text and data. They are now standard features in a wide range of languages and popular tools, including Perl, Python, Ruby, Java, VB.NET and C# (and any language using the .NET Framework), PHP, and MySQL.
If you don't use regular more » expressions yet, you will discover in this book a whole new world of mastery over your data. If you already use them, you'll appreciate this book's unprecedented detail and breadth of coverage. If you think you know all you need to know about regularexpressions, this book is a stunning eye-opener.
As this book shows, a command of regular expressions is an invaluable skill. Regular expressions allow you to code complex and subtle text processing that you neverimagined could be automated. Regular expressions can save you time and aggravation. They can be used to craft elegant solutions to a wide range of problems. Once you've mastered regular expressions, they'll become an invaluable part of your toolkit. You will wonder how you ever got by without them. « less
Perl soared to popularity as a language for creating and managing web content, but with LWP (Library for WWW in Perl), Perl is equally adept at consuming information on the Web. LWP is a suite of modules for fetching and processing web pages.
The Web is a vast data source that contains everything from more » stock prices to movie credits, and with LWP all that data is just a few lines of code away. Anything you do on the Web, whether it's buying or selling, reading or writing, uploading or downloading, news to e-commerce, can be controlled with Perl and LWP. You can automate Web-based purchase orders as easily as you can set up a program to download MP3 files from a web site. « less
XML is a text-based markup language that has taken the programming world by storm. More powerful than HTML yet less demanding than SGML, XML has proven itself to be flexible and resilient. XML is the perfect tool for formatting documents with even the smallest bit of complexity, from Web pages to legal more » contracts to books. However, XML has also proven itself to be indispensable for organizing and conveying other sorts of data as well, thus its central role in web services like SOAP and XML-RPC.
As the Perl programming language was tailor-made for manipulating text, few people have disputed the fact that Perl and XML are perfectly suited for one another. The only question has been what's the best way to do it. That's where this book comes in. « less
An Introduction to Perl for Biologists
This book shows biologists with little or no programming experience how to use Perl, the ideal language for biological data analysis. Each chapter focuses on solving a particular problem or class of problems, so you'll finish the book with a solid understanding of Perl basics, a collection of programs more » for such tasks as parsing BLAST and GenBank, and the skills to tackle more advanced bioinformatics programming. « less
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 more » 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. « less
The Perl/Tk Pocket Reference is a companion volume to Learning Perl/Tk, an O'Reilly Animal Guide. Learning Perl/Tk is a tutorial for Perl/Tk, the extension to Perl for creating graphical user interfaces. With Tk, Perl programs can be window-based rather than command-line based, with buttons, entry fields, more » listboxes, menus, scrollbars, balloons, tables, dialogs, and more. And Perl/Tk programs run on UNIX and Windows-based computers.
This small book is a handy reference guide geared toward the advanced Perl/Tk programmer. Novice Perl/Tk programmers will find that its compact size gives them a global view of Perl/Tk's capabilities; they can then turn to Learning Perl/Tk for details. The Perl/Tk Pocket Reference describes every Perl/Tk graphical element, including general widget and variable information, callbacks, geometry management, bindings, events, and window management, as well as composite widget, font, and image creation and manipulation commands. « less
