Ruby工具来浏览已安装的宝石代码 [英] Ruby tool to browse through installed gems code

问题描述

目前为了了解它是如何工作的，我必须去github，搜索gem意识到代码来自于依赖关系，搜索其他gem的代码repo，意识到这是另一个gem，找到它，找到类，然后从一个类到另一个类，并打开很多浏览器选项卡。 / p>

我在Linux上使用崇高文本。是否有一些工具可以让我直接从gem中访问代码？

你可以使用 pry with 源代码浏览。

这是一个类似于IRB的控制台，您可以查看写入的任何类/方法的定义简单的Ruby。

下面是一个例子 rgeo gem：

 > pry 
 [1] pry（main）>需要'rgeo'
 => true 
 [2] pry（main）> show-source RGeo :: Cartesian.factory 
 
 From：〜/ .rvm / gems / ruby​​-2.3.1 / gems / rgeo-0.6.0 / lib / rgeo / cartesian / interface.rb @第27行：
所有者：＃< Class：RGeo :: Cartesian> 
可见性：public 
行数：7 
 $ b $ def preferred_factory（opts_ = {}）
 if :: RGeo :: Geos.supported？ 
 :: RGeo :: Geos.factory（opts_）
 else 
 simple_factory（opts_）
 end 
 end 
  

I am using a gem and I have trouble figuring out how to use a specific method.

Currently to understand how it works, I have to go to github, search the gem realise the code is from a dependency, search the code repo for the other gem, realise it's another gem, locate it, find the class, and from there go from one class to another with a lot of browsers tabs open.

I am on Linux using sublime text. Is there some tool that would allow me to directly access the code from a gem ?

解决方案

You could use pry with source-browsing.

It's a console similar to IRB, and you can view the definition of any class/method that is written in plain Ruby.

Here's an example with rgeo gem :

> pry                                                                                                               
[1] pry(main)> require 'rgeo'
=> true
[2] pry(main)> show-source RGeo::Cartesian.factory

From: ~/.rvm/gems/ruby-2.3.1/gems/rgeo-0.6.0/lib/rgeo/cartesian/interface.rb @ line 27:
Owner: #<Class:RGeo::Cartesian>
Visibility: public
Number of lines: 7

def preferred_factory(opts_ = {})
  if ::RGeo::Geos.supported?
    ::RGeo::Geos.factory(opts_)
  else
    simple_factory(opts_)
  end
end
