內容簡介

你能夠編寫真正優雅的Ruby代碼嗎？《Ruby最佳實踐》正是為想要像專家那樣使用Ruby的程式設計師所準備的。《Ruby 最佳實踐(影印版)》由Ruby項目Prawn的開發者所著，簡潔地向你闡釋如何使用Ruby編寫優美的應用程式接口和領域特定語言。此外，還包括如何套用函式式編程的思想和技術，使代碼更簡潔，使你更有效率。通過《Ruby 最佳實踐(影印版)》，你將會學到如何編寫可讀性更高，表達能力更強的代碼，以及許多其他方面的內容。

《Ruby最佳實踐》將會幫助你：

* 理解Ruby代碼塊所蘊含的神秘力量

* 學習如何在不破壞原有Ruby代碼的情況下進行調整，例如運行時在模組內糅合

* 探究測試與調試中的細節，以及如何從易測性出發進行設計

* 學習通過讓事情保持簡單來編寫快速代碼

* 用於文本處理和檔案管理的開發策略，包括正則表達式

* 理解為什麼會發生錯誤以及錯誤是如何發生的

* 利用Ruby的多語言特性減少文化障礙

《Ruby 最佳實踐(影印版)》還包含多個章節對測試代碼、設計應用程式接口以及項目維護做了全面介紹。《Ruby最佳實踐》將陪伴你學習如何將這門豐富、優美的語言發揮到極致。
