ruby文件操作

require 'app/configuration'
module RubyAMF
  module Configuration
    #set the service path used in all requests
    # RubyAMF::App::RequestStore.service_path = File.expand_path(RAILS_ROOT) + '/app/controllers'

    # => CLASS MAPPING CONFIGURATION
    ClassMappings.register(
      :actionscript  => 'Stock',
      :ruby          => 'Stock',
      :type          => 'active_record',
      :attributes    => ["code", "name"])
    end
end 

 上面算是整个文件吧，之后我想在另一个同等级路径文件下要操作这个文件

File.open("rubyamf_config.rb") do |file|
    while line = file.gets
      unless line.include?("#")
      line.scan(//)
        print line
      end
    end
    file.close
  end 

怎么操作呢，1.不要注释，之后把下面的代码写到一个数组里，如最下面的模式

ClassMappings.register(
      :actionscript  => 'Stock',
      :ruby          => 'Stock',
      :type          => 'active_record',
      :attributes    => ["code", "name"])

#模式：
{'ClassMappings.register' => ['actionscript' => 'Stock', 'ruby' => 'Stock', 'type' => 'active_record', 'attributes' => ["code", "name"]]}

ruby操作这些玩意还不会呢！哎！如能回答，另加完我得分，不知道javaeye能不能追加？

[code="ruby"]

content = File.read("rubyamf_config.rb")
result =content.gsub(/#.*$/,"").sub(/ClassMappings.register(\s+(.*?)end/m) do
"{" +
'ClassMappings.register'.inspect +
" => " +
"[" +
eval("{#{$1.sub(/\s+$/,"").chop}}").map{|k,v| k.to_s.inspect + " => " + v.inspect}.join(", ") +
"]" +
"}"
end
File.open("rubyamf_config.rb", "w+"){|f| f.write result.gsub("\"","'")}
[/code]

结果：
[code="ruby"]require 'app/configuration'
module RubyAMF
module Configuration

{'ClassMappings.register' => ['type' => 'active_record', 'attributes' => ['code', 'name'], 'ruby' => 'Stock', 'actionscript' => 'Stock']}

end

[/code]
有一点问题：ruby里hash是无序的，结果中的顺序会有变化。感觉对你这个问题没有什么影响。
