內容簡介
本書是0’Reilly具有里程碑意義的Perl教科書系列的第三本,該系列包括《LearningPerl》(最為暢銷的一本介紹Perl基礎語法的書,簡體中文版由東南大學出版社出版)、《Intermediate Perl》(一本Perl程式設計師必備的指導如何創建可重用的Perl軟體的書)和《精通Perl》。《精通Perl》由淺入深地剖析了Perl特殊模組的工作機理、細緻詳盡地闡述了慣用的Perl 編程思想和技術,這些知識必能協助你在開發Perl程式時遊刃有餘,達成所需。
本書解釋了該如何:使用高級正則表達式,包括全局匹配、前後查詢匹配、可讀的正則表達式以及對正則表達式的調試;使用安全可靠的編程技術,避免常見的編程問題;剖析Perl運行時數據並作基準測試,繼而有針對性地進行性能最佳化;重新組織Perl代碼,使其更具自我表達力,增強可讀性;查看Perl如何實現對包變數的跟蹤維護,你可以用類似的技巧玩出更多有用的花樣來;動態定義子程式,從容化解普通過程式編程帶來的劣勢;臨時修改或調整相關的模組,在不修改原始碼的情況下修復代碼存在的問題;在不觸及代碼的情況下,讓用戶自行對程式進行配置;偵測Perl沒有報告的那些錯誤並向用戶匯報;套用Log4Perl模組,從Perl程式的運行日誌獲取有價值的信息;存儲相關數據以便後續再次運行該程式或其他程式時可以訪問該數據,以及如何通過網路傳送數據以Perl模組的形式編寫應用程式,以便使用現成的測試工具並輕鬆發布。
本書將帶你一路揭示這些問題的答案,讓你從容地成為能夠發現並解決疑難雜症的專家。
《精通Perl》一書並非一堆奇技的簡單集合,而是著重介紹Perl編程的思維方式,這是每一個合格的程式設計師都應當掌握的,並且應當藉此解決實際生活中各式問題,如調試代碼、維護程式以及配置等。
