如何将ruby gem添加到"require"的include路径中

我正在创造我期望的红宝石宝石.任何人都有一个很好的链接指向将简单的库或插件转换为gem的教程？另外,特别是,Ruby使用什么来允许需要查找宝石？它似乎不仅仅是将文件放在gem路径中(或者我的配置搞砸了？).

谢谢

实际上并不难以手动执行此操作.假设您有一个whatever.rb要作为gem分发的库.

建立一个目录lib,并把副本whatever.rb在lib/whatever.rb.

制作一个文件whatever.gemspec,并在其中放入以下内容,填写适当的值:

 Gem::Specification.new do |spec|
   spec.name = 'the-name-of-your-gem'
   spec.version ='0.0.1'

   # this is important - it specifies which files to include in the gem.
   spec.files = ["lib/whatever.rb"]

   # optional, but useful to your users
   spec.summary = "A more longwinded description of your gem"
   spec.author = 'Your Name'
   spec.email = 'you@yourdomain.com'
   spec.homepage = 'http://www.yourpage.com'

   # you did document with RDoc, right?
   spec.has_rdoc = true

   # if you have a ruby forge project
   spec.rubyforge_project = 'your-project-name-on-rubyforge'

   # if you have any dependencies on other gems, list them thusly
   spec.add_dependency('hpricot')
   spec.add_dependency('log4r', '>= 1.0.5')
 end

现在,要构建gem,请使用以下gem build命令:

% gem build whatever.gemspec
Successfully built RubyGem
Name: the-name-of-your-gem
Version: 0.0.1
File: the-name-of-your-gem-0.0.1.gem
%

您可以gem install the-name-of-your-gem-0.0.1.gem 使用在脚本中使用库来本地测试,然后在顶部执行以下操作:

require 'rubygems' # puts gem libraries in the require path
require 'whatever' # loads your library

有关gemspec文件中各种设置的更多信息,请查看GemSpec参考.

就个人而言,我也使用rubygems来打包可执行脚本,并且发现它非常方便.
