Crystal 程式語言
這裡是 Crystal 語言的教學文件，由 Crystal-TW 翻譯，原文連接在此。
Crystal 是一個程式語言語言，並嘗試完成以下目標：
- Ruby 風格語法（但不會完全相容 Ruby）
- 自動型別推導以及靜態型別檢查
- 容易撰寫 C 函式庫綁紮(Binding)
- 編譯時期展開巨集並產生最佳化程式碼
- 產生高效原生碼
Crystal's standard library is documented in the API docs.
協助翻譯
若內容中有任何錯誤或對於某些章節需要更多說明， 歡迎您一起來貢獻這份中文文件，只需要提交 Pull Request 至以下專案：
https://github.com/crystal-tw/docs
另外，目前所有的討論都會在 GitHub Issue Tracker 以及 Gitter 上進行。
雖然目前沒有強制規範的規則，但為了確保閱讀順暢，翻譯前請先閱讀已經翻譯好的部分以熟悉慣例，部分規則可以參考中文文案排版指北。
如何建置
本文件使用 Markdown 語法編寫，並使用 GitBook Toolchain 輸出 HTML（請先安裝 Node.js 及 npm）。
Markdown 語法及規則可以參考 Markdown 文件。
$ git clone https://github.com/crystal-tw/docs.git
$ cd docs
$ npm install -g gitbook-cli@2.3.0
$ npm install
$ gitbook install
$ gitbook serve
Live reload server started on port: 35729
Press CTRL+C to quit ...
info: 8 plugins are installed
info: loading plugin "ga"... OK
...
Starting server ...
Serving book on http://localhost:4000
產生的 HTML 將放置於 _book 目錄下。
我們也提供 Docker 環境來避免在本機安裝相依套件：
$ docker-compose up
...
gitbook_1 | Starting server ...
gitbook_1 | Serving book on http://localhost:4000
gitbook_1 | Restart after change in file node_modules/.bin
...
已知慣例
雖然慣例僅僅只是慣例，但這邊還是整理出一些大家比較容易掌握的要點：
- 文字中若需補充原文可以使用
<small>標籤，如：
# 字串 <small>String</small>
- 儘量避免使用第二人稱，將
You改以第一人稱複數表達，如：
In type restrictions, generic type arguments and other places where a type is expected, **you** can use a shorter syntax, as explained in the type:
會翻譯成：
當使用在型別限制時，於任何泛型型別參數或是其他需要填寫型別的地方，「我們」也可以使用簡短的語法來表示序組的型別，這在型別語法一章中會解釋：
- 使用相對路徑以及 .md 後綴來建立不同章節之間的連接。
十分感謝您的參與 <(_ _)>
