一些gem的簡要翻譯（歡迎提出問題共同討論）

寫這篇文章主要有兩方面用途

1.但願給rails同行必定的幫助，翻譯水平有限，貼出中英文，翻譯有誤的地方歡迎指正，很是感謝，轉載請標明出處，謝謝。

2.加深做者對gem的理解，有須要更詳細瞭解安裝以及使用的朋友能夠點擊文章中的連接進入gem sources詳細介紹。

3.不按期更新

 

一.mjackson/rack-accept

版本：0.4.5

Rack::Accept is a suite of tools for Ruby/Rack applications that eases the complexity of building and interpreting the Accept* family of HTTP request headers.

Some features of the library are:

• Strict adherence to RFC 2616, specifically section 14
• Full support for the Accept, Accept-Charset, Accept-Encoding, and Accept-Language HTTP request headers
• May be used as Rack middleware or standalone
• A comprehensive test suite that covers many edge cases

Rack::Accept是一套Ruby/Rack應用的工具，該工具簡化了創建應用的複雜性，解釋了可接受的Http請求頭系列。本庫的一些功能以下：

        1.嚴格遵照RFC 2616,具體請看section 14

　　 2.全面支持1中的Accept, Accept-Charset, Accept-Encoding, 和Accept-Language HTTP請求頭。

　　 3.能夠獨立使用或者用作RACK中間件

　　 4.擁有一個很全面的測試套間，涵蓋了許多邊緣狀況

 

二.dkubb/descendants_tracker

版本：0.0.4

Small module to track descendants in an unobtrusive way.

一些不顯眼的方式追蹤派生類的模塊

 

三.slim-template/html2slim

Script for converting HTML and ERB files to slim (slim-lang.org).

It's not perfect, but certainly it helps a lot!

It's based on Hpricot. Yeah, I'm old school.

本gem是把HTML和ERB文件轉換爲silm模板語言的腳本，想了解slim的出門右轉（slim-lang.org）

它不完美，可是無疑能幫助你不少！

它基於Hprico。呵呵，我是一個老司機。

 

四.rails/sass-rails

Official Ruby-on-Rails Integration with Sass

This gem provides official integration for Ruby on Rails projects with the Sass stylesheet language.

官方Ruby-on-Rails集成Sass

本gem提供Ruby on Rails與Sass語言的官方集成

 

五.lautis/uglifier

 Uglifier minifies JavaScript files by wrapping UglifyJS to be accessible in Ruby

本gem壓縮JavaScript文件包裝爲UglifyJS來訪問ruby。

 

六.slim-template/slim-rails

 

slim-rails provides Slim generators for Rails 3 and 4. It was based on haml-rails and it does basically the same:

• Any time you generate a controller or scaffold, you'll get Slim templates (instead of ERB)
• When your Rails application loads, Slim will be loaded and initialized automatically
• Slim templates will be respected by the view template cache digestor

slim_rails提供了爲Rails3和Rails4的Slim語言生成器，它基於haml-rails，並且他們特色基本上是相同的，以下：

　  1.不管什麼時候何地你用rails生成了一個控制器或者腳手架，你都會獲得Slim語言的模板（替代ERB，所以ERB文件就消失了）。

　  2.當你加載Rails應用時，Slim將會自動初始化和加載。

　  3.當訪問緩存器的時候，Slim模板將會被慎重對待。

 

七.plataformatec/devise

This README is also available in a friendly navigable format.

Devise is a flexible authentication solution for Rails based on Warden. It:

• Is Rack based;
• Is a complete MVC solution based on Rails engines;
• Allows you to have multiple models signed in at the same time;
• Is based on a modularity concept: use only what you really need.

It's composed of 10 modules:

• Database Authenticatable: encrypts and stores a password in the database to validate the authenticity of a user while signing in. The authentication can be done both through POST requests or HTTP Basic Authentication.
• Omniauthable: adds OmniAuth (https://github.com/intridea/omniauth) support.
• Confirmable: sends emails with confirmation instructions and verifies whether an account is already confirmed during sign in.
• Recoverable: resets the user password and sends reset instructions.
• Registerable: handles signing up users through a registration process, also allowing them to edit and destroy their account.
• Rememberable: manages generating and clearing a token for remembering the user from a saved cookie.
• Trackable: tracks sign in count, timestamps and IP address.
• Timeoutable: expires sessions that have not been active in a specified period of time.
• Validatable: provides validations of email and password. It's optional and can be customized, so you're able to define your own validations.
• Lockable: locks an account after a specified number of failed sign-in attempts. Can unlock via email or after a specified time period.

Devise is guaranteed to be thread-safe on YARV. Thread-safety support on JRuby is in progress.

本自述文件也有更友好的可操縱的格式頁面

Devise是一個基於Warden的，更加靈活的身份驗證的rails解決方案。

　　1.基於Rack

　　2.是一個基於Rails引擎的完整MVC解決方案

　　3.容許多個模塊同時登錄

　　4.基於模塊化的概念：只使用你須要的

它由10個模塊組成：

　　1.數據庫驗證：註冊信息的同時將密碼加密而且儲存在數據庫中以便於身份驗證，不管提交POST請求仍是HTTP基自己份驗證的狀況下都支持。

　　2.Omniauthable驗證：添加了OmniAuth(https://github.com/intridea/omniauth)身份驗證。

　　3.郵件確認：在登錄時發送驗證郵件確認郵件已被確認。

　　4.重獲密碼：從新設置密碼而且發送重設密碼郵件

　　5.註冊：控制已註冊用戶的功能，已註冊用戶能夠編輯和刪除他們的帳戶。

　　6.記憶cookie功能：管理建立和清楚用戶已保存的cookie的記憶令牌。

　　7.可追蹤的：追蹤帳戶的數量，時間以及IP地址。

　　8.會話超時管理：在特定的時間內會話到期。

　　9.驗證信息：提供驗證郵件和密碼。此功能是可選擇和定製的，因此你能夠定義你本身須要的驗證。

　　10.可鎖定的：在指定數量的失敗登錄後鎖定帳戶，能夠經過限定時間或者郵件驗證解鎖帳戶。

Devise在YARV虛擬機上是第三方安全的，在Jruby上第三方安全正在進行中。

八.rails/jbuilder

Create JSON structures via a Builder-style DSL

Jbuilder gives you a simple DSL for declaring JSON structures that beats massaging giant hash structures. This is particularly helpful when the generation process is fraught with conditionals and loops.

用相似ruby語法的領域語言（看了下代碼,仍是有些不同）創建JSON結構的文件

使用Jbuilder，它能給你一個簡單的DSL語言，JSON結構能控制偉大的哈希結構.當你創建一個條件句或者環形結構時，會特別有幫助。

九.rails/spring

Spring is a Rails application preloader. It speeds up development by keeping your application running in the background so you don't need to boot it every time you run a test, rake task or migration.

spring是一個rails應用預載器。他大大加快了開發效率，不管你運行測試，仍是rake任務或數據，他都會保持後臺運行，因此免去了你時刻啓動的煩惱。
