Livres Perl

Si vous êtes comme moi bioinformaticien, ce livre n'apporte rien de plus... par contre si vous voulez découvrir, comprendre et appliquer la démarche de bioanalyste, ce livre est fait pour.
Bonne découverte !

The appearance of the second edition of CGI Programming with Perl heralds the beginning of the neoclassical era of Web service. CGI--or common gateway interface--is the original back end for client-driven, dynamic Web-page service and deserves consideration as the Romulus of the Internet Empire. But, where first-edition author Gundavaram described the lonely Romulus laying the brick foundation of dynamic Web-page service in 1996, second-edition collaborators Guelich and Birznieks have pitched in to resurrect Romulus amid the crowded streets of modern Rome. Why bother? Surely four years have brought technological revolutions (Java, PHP, ASP, ColdFusion) that render CGI's original brick-by-brick approach as obsolete as, say, Roman mythology--or bricks and mortar. And yet not. It is an ambiguous blessing that the original CGI persists, adhering to the underside of Web service by the duct tape that is Perl. This point is not missed by Guelich, Gundavaram, and Birznieks, whose advocacy of CGI is both bolstered by the growing applications module base of Perl and tempered by their awareness of CGI's structural limitations. Both new and returning readers of CGI Programming with Perl should browse the last chapter first in order to appreciate the proposed solutions to CGI's greatest sin: its impractical slowness in a world of a million-hits-per-day Web service. The chapter describes CGI-compatible FastCGI and mod_perl technologies that circumvent the process-spawning slowness of the simple CGI. Advanced users might want to skip directly to O'Reilly's fine mod_perl tome, Writing Apache Modules with Perl and C, by Lincoln Stein and Doug MacEachern. The authors' second pass at CGI pedagogy is a lucid, honest, and expanded account that develops functionality of dynamic Web pages in a rational progression--from HTML client-server and CGI syntax basics to general input/output, forms, e-mail, graphics, and simple database applications, including maintaining client state and data persistence under the otherwise stateless HTTP protocol. The authors offer synopses of cookies, JavaScripting, server security, and XML, all of which are described in detail in other books. Whether or not neoclassical CGI is fast enough for your purposes--perhaps for guarded intranets--bear in mind that CGI is the standard to which every other Web server has had to respond. The second edition of CGI Programming with Perl is still the best introduction to the classics. --Peter Leopold, Amazon.com

Niveau : programmeur confirmé
Ce livre, écrit par deux experts en Perl, est la troisième édition française d'un standard dans la programmation avec ce langage de script gratuit et largement diffusé dans le monde Unix. Même si l'ouvrage se présente comme une "introduction", il s'agit en réalité d'un guide complet qui parcourt tous les aspects du langage.
On aborde tour à tour la syntaxe proprement dite, la structuration des programmes, les structures de données de hachage, l'exploitation des expressions régulières, la manipulation de fichiers, l'utilisation de bases de données simples (DBM, fourni avec Perl). Les applications pratiques de chaque fonctionnalité sont décrites précisément, dans un style vivant et sympathique. Les nombreux exemples de code sont analysés d'une façon très fine, pour être repris et adaptés le mieux possible aux situations concrètes que rencontrent les programmeurs.
Des exercices sont proposés à la fin de chaque chapitre, et leur corrigé est reporté en annexe. On peut se référer également, pour une utilisation optimale de Perl, à l'ouvrage Maîtrise des expressions régulières, de Jeffrey Friedl, chez le même éditeur. --Véronique Spir

Avery good book about python programming! lots of shortcuts and examples for a less performance wasting code! how to make a fast tcp client? Working with DB's? manipulating W2K/NT environement (unix also)? are questions that will be answered in this book...and much much more!!!!

Larry Wall wrote Perl and he wrote Programming Perl. Better yet, he writes amusingly and well--all of which comes across in this latest edition of the definitive guide to the language. Like Topsy, Perl just grew, and as a result so has Programming Perl. It's now over 1,000 pages but needs to be as it does several different jobs. Firstly, it's an introduction to the Perl language for those new to programming. It's a guide for those coming from other languages and it's a Perl language reference. Larry Wall is a linguist, among his other interests, and perhaps for this reason Perl is a peculiarly flexible language with many routes to achieving the same ends, as the authors ably demonstrate. It's also extensible in several ways, designed to work with many other languages and, as it's largely interpreted, Perl programs tend to run unmodified on a variety of platforms--though platform-specific Perl modules and programming practices are also discussed. A major strength of Programming Perl is the way subject areas are approached from several directions. This constant viewpoint-shifting eliminates blind spots in the reader's understanding as well as providing a pleasing echo of the way Perl itself can take many routes from here to there. Because the Perl community is both knowledgeable and active the language covers a lot more ground than it did at the time the last edition of Programming Perl was published. Even if you have both previous editions you'll want this latest version--if only for the new jokes. --Steve Patient

By combining the rough-and-ready Perl language with the graphical user interface (GUI) capabilities of the Tk toolkit, Perl/Tk makes it easy to write event-based GUI applications quickly--once you know what you're doing. Learning Perl/Tk shows you how to build GUIs with everyone's favorite public-domain programming language. This book focuses only on GUIs--it leaves in-depth exploration of the Perl language to other books. (Learning Perl is the best of that genre.) Assuming only a basic familiarity with Perl, Learning Perl/Tk shows you what you need to know to create graphical front ends for Perl programs. Author Nancy Walsh starts with a quick orientation, showing you how to set up Perl/Tk and giving you some simple examples of what GUI source code looks like. Then, she details the use and functions of geometry managers, which the Tk module uses to arrange interface elements. From there, she explores each widget individually, showing how to use buttons, checkbuttons, radiobuttons, labels, entries, and more. She also addresses event handlers. Her discussion of each widget is clear and liberally sprinkled with examples. One appendix lists the default values of the Tk widgets in tabular form; another spotlights the differences among versions of Perl and Tk for various operating systems. A final appendix explores the font-management capabilities of Tk 8.0. This book doesn't come with a companion disk, and it would be nice to have the examples available locally. However, the publisher maintains a library of related files on its Web site. --David Wall
