查看宝石的源代码 [英] Viewing a Gem's Source Code

问题描述

在这里，Ruby对于生态系统不熟悉的Dabbler / newbie很抱歉，如果这是超级问题之一。

有没有办法查看所有由gem安装的文件和/或源代码？也就是说，我只是跑了

  $ gem install sass 
  

而sass gem现在是我本地系统的一部分
$ b $

  $ gem list --local 
 ... 
 sass（3.1.16，3.1.2）
 ... 
  

我想知道我的系统上放置了什么 gem install 命令。有没有可以运行的命令来查看gem安装的文件 all ？

经过一些Google搜寻之后， man gem 和 gem帮助命令，我发现了内容命令。

$ gem contents sass

然而，当我运行此命令前面提到的sass gem，我得到了以下结果：

$ $ $ code $ ... rvm / gems / ruby​​-1.9.2-p180 / gems / sass-3.1.16 / test / sass / engine_test.rb

... /。rvm / gems / ruby​​-1.9.2-p180 / gems / sass-3.1.16 / bin / scss

然而，这个清单似乎并不完整，因为我知道那里

  ... /。rvm / gems / ruby​​-1.9.2-p180 / gems / sass-3.1中的文件。 2 / lib / 
  

为什么内容不是显示来自 lib ？

的文件是否可以为 gem 安装程序在gem文件夹以外安装文件？

是否有可以显示由gem安装的所有内容的命令？

解决方案

gem有一个解压命令： http://guides.rubygems.org/command-reference/#gem-unpack

  gem unpack rake 
 ls rake-0.4.3 / 
  

Ruby dabbler/newbie here who's not familiar with the ecosystem, so apologies if this is one of those super duh questions.

Is there a way to view all the files and/or source code installed by a gem? That is, I just ran

$ gem install sass

And the sass gem is now a part of my local system

$ gem list --local
...
sass (3.1.16, 3.1.2)
...

I want to know what the gem install command put on my system. Is there a command I can run to see all the files installed by the gem?

After some googling, man gem and gem help commands, I discovered the contents command.

$ gem contents sass

However, when I run this command with the aforementioned sass gem, I get the following results

.../.rvm/gems/ruby-1.9.2-p180/gems/sass-3.1.16/test/sass/engine_test.rb
.../.rvm/gems/ruby-1.9.2-p180/gems/sass-3.1.16/test/sass/functions_test.rb

.../.rvm/gems/ruby-1.9.2-p180/gems/sass-3.1.16/bin/scss

However, this list seems incomplete as I know there are files in

.../.rvm/gems/ruby-1.9.2-p180/gems/sass-3.1.2/lib/

Why does contents not show the files from lib?

Is it possible for a gem installer to install files outside of the gems folder?

Is there a command that can show everything installed by a gem?

解决方案

gem has an unpack command: http://guides.rubygems.org/command-reference/#gem-unpack

gem unpack rake
ls rake-0.4.3/
