我有一个构建器扩展,我将其打包为 gem。我有一组要添加到包中的脚本。目前,我将这些脚本存储为我正在写入文件的大文本块。我希望拥有可以直接复制或读/写回的单个文件。我希望将这些文件打包到 gem 中。我将它们打包没有问题(只需将它们粘贴在之前的文件系统中rake install
),但我不知道如何访问它们。有宝石资源捆绑类型的东西吗?

基本上有两种方式,
1) 您可以使用以下命令在 gem 中加载与 Ruby 文件相关的资源__FILE__
:
def path_to_resources
File.join(File.dirname(File.expand_path(__FILE__)), '../path/to/resources')
end
2)您可以将任意路径从您的 Gem 添加到$LOAD_PATH
变量,然后步行$LOAD_PATH
查找资源,例如,
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 = Dir.glob("lib/**/*") + %w{History.txt Manifest.txt} +
Dir.glob("path/to/resources/**/*")
# If you have resources in other directories than 'lib'
spec.require_paths << 'path/to/resources'
# 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 any dependencies on other gems, list them thusly
spec.add_dependency('hpricot')
spec.add_dependency('log4r', '>= 1.0.5')
end
进而,
$LOAD_PATH.each { |dir| ... look for resources relative to dir ... }
