Programming Perl

Produktbeschreibung

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 thatâ€Ös 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 Perlâ€Ös 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

Autoreninfo

Tom Christiansen is a freelance consultant specializing in Perltraining and writing. After working for several years for TSR Hobbies (ofDungeons and Dragons fame), he set off for college where he spent a yearin Spain and five in America, dabbling in music, linguistics, programming, and some half-dozen different spoken languages. Tom finally escaped UW-Madison with B.A.s in Spanish and computer science and an M.S. incomputer science.He then spent five years at Convex as a jack-of-all-trades working oneverything from system administration to utility and kernel development,with customer support and training thrown in for good measure. Tom alsoserved two terms on the USENIX Association Board of directors. With over fifteen years' experience in UNIX system administration andprogramming, Tom presents seminars internationally.Larry Wall originally created Perl while a programmer at Unisys. He now works full time guiding the future development of the language as a researcher and developer at O'Reilly & Associates. Larry is known for his idiosyncratic and thought-provoking approach to programming, as well as for his groundbreaking contributions to the culture of free software programming. He is the principal author of the bestselling Programming Perl, known colloquially as "the Camel book."Jon Orwant founded The Perl Journal and received the White Camel lifetime achievement award for contributions to Perl in 2004. He's Engineering Manager at Google, where he leads Patent Search, visualizations, and digital humanities teams. For most of his tenure at Google, Jon worked on Book Search, and he developed the widely used Google Books Ngram Viewer. Prior to Google, he was CTO of O'Reilly, Director of Research at France Telecom, and a Lecturer at MIT. Orwant received his doctorate from MIT's Electronic Publishing Group in 1999.
