|
|
<p>我們假設你有一個或多個其他編程語言的使用經歷, 不過是類似 C、c++,和Java 的編譯型語言,
|
|
還是類似 Python, Ruby, JavaScript 的腳本語言, 因此我們不會相對完全的編程語言初學者那樣解釋所有的細節.
|
|
因爲Go的語言的 變量,常量,表達式,控製流和函數等語法也是類似的.</p>
|
|
<p>第一章包含了Go敎程的基本結構, 通過十幾個程序介紹了用Go如何實現 類似讀寫文件, 文本格式化, 創建圖像,
|
|
網絡客戶端和服務器通訊 等日常工作.</p>
|
|
<p>第二章描述了一個Go程序的基本元素結構, 變量, 定義新的類型, 包和文件, 和作用域. 第三章討論了數字, 布爾值, 字符串和常量, 併演示了如何顯示和處理Unicode. 第四章描述了複合類型, 從簡單的數組, 字典, 切片, 到動態列表. 第五章涵蓋了函數, 併討論了錯誤處理, panic 和 recover, 和 defer 語句.</p>
|
|
<p>第三章討論了數字、布爾值、字符串和常數,併解釋顯示處理Unicode。
|
|
第四章描述了複合類型,類型建立使用數組,從簡單的地圖,結構,和切割的方法去動態列表。第五章涵蓋了函數和討論錯誤處理,恐慌和恢複,而推遲的陳述。</p>
|
|
<p>第一章到第五章是基礎部分, 任何主流命令式語言的一部分都是類似的. 雖然有時候Go的語法和風格會有自己的特色, 但是大多數程序員將很快適應.
|
|
剩下的章節是Go中特有的部分: 方法, 接口, 併發, 包, 測試和反射等.</p>
|
|
<p>Go的面向對象是不同尋常的. 它沒有類層次結構, 甚至沒有類; 僅僅是通過組合(而不是繼承)簡單的對象來構建複雜的對象.
|
|
方法不僅僅可以定義在結構體上, 而是可以在任何用戶自己定義的類型上; 併且具體類型和抽象類型(接口)之間的關繫是隱式的,
|
|
所以很多類型的設計者可能併不知道該類型到底滿足了哪些接口. 方法在第六章討論, 接口在第七章將討論.</p>
|
|
<p>第八章討論了基於順序通信進程(CSP)的概念的併發編程, 使用 goroutines 和 channels. 第九章討論了更爲傳統的基於共享變量的併發性.</p>
|
|
<p>第十章描述了包機製, 包的組織結構. 本章還展示了如何利用有效的利用Go自帶的工具,
|
|
通過一個命令提供了編譯, 測試, 基準測試, 代碼格式化, 文檔, 和許多其他任務.</p>
|
|
<p>第十一章討論單元測試, Go的工具和標準庫中集成了輕量級的測試功能, 從而避免了采用複雜強大的測試框架. 測試庫提供一些基本的構建, 如果有必要可以構建更複雜的測試抽象.</p>

<p>第十二章討論了反射, 一個程序在運行期間來檢視自己的能力. 反射是一個強大的工具, 不過要謹慎地使用; 本章通過用反射實現一些重要的Go庫來展示了反射的用法. 第十三章解釋了低級編程的細節, 通過使用 unsafe 包來繞過Go的類型繫統, 有時這是必要的.</p>
|
|
<p>每一章會有一些練習, 你可以根據你對Go語言的理解, 然後脩改書中的例子來探索Go的其他用法.</p>
|
|
<p>書中所有的代碼都可以從 gopl.io 上的 Git 倉庫下載. go get可以根據每個例子的其導入路徑方便地穫取/構建/併安裝. 你需要選擇一個目録作爲工作空間, 然後將GOPATH環境指向這個工作目録.</p>
|
|
<p>Go工具將在必要時創建的相應的目録. 例如:</p>
|
|
<pre><code>$ export GOPATH=$HOME/gobook # 選擇工作目録
|
|
$ go get gopl.io/ch1/helloworld # 穫取/編譯/安裝
|
|
$ $GOPATH/bin/helloworld # 運行
|
|
Hello, 世界 # 這是中文, 不是日文
|
|
</code></pre><p>要運行這些例子, 你需要安裝Go1.5以上的版本.</p>
|
|
<p>$ go version
|
|
go version go1.5 linux/amd64</p>
|
|
<p>如果你用的是其他的操作繫統, 請參考 <a href="https://golang.org/doc/install" target="_blank">https://golang.org/doc/install</a> 提供的説明安裝.</p>
