商品描述

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

商品描述(中文翻譯)

自1991年首次出版以來,《Programming Perl》迅速成為Perl的無可爭議的聖經,至今仍是這個高度實用語言的首選指南。Perl最初是一個功能強大的文本處理工具,但很快演變成一個通用的程式語言,幫助數以千計的程式設計師、系統管理員和愛好者完成工作。

在這本期待已久的《駱駝書》更新版中,三位著名的Perl作者介紹了該語言的最新版本Perl 5.14,並預覽了即將推出的5.16版本的功能。在一個越來越需要Unicode進行文本處理的世界中,Perl提供了任何主要語言中最好且最不痛苦的Unicode支援,無縫地將Unicode整合到各個地方,包括Perl最受歡迎的功能:正則表達式。

此次更新涵蓋的重要功能包括:

- 新的關鍵字和語法
- I/O層和編碼
- 新的反斜線轉義
- Unicode 6.0
- Unicode字形群集和屬性
- 正則表達式中的命名捕獲
- 遞歸和文法模式
- CPAN的擴展覆蓋範圍
- 目前的最佳實踐
