Usage

if you want to collect data,

data = Screening::Data.new
data.start do |element|
   element.title   = "title1"
   element.content = "content1"
end
data.start do |element|
   element.title   = "fake"
   element.content = "fake content"
end

or

data.push({title: "title2", content: "content2"})    
p data   # => [{:title=>"title1", :content=>"content1"}, {:title=>"fake", :content=>"fake content"}, {:title=>"title2", :content=>"content2"}]

if you want to classify data,

data.classify(:high, :title, lambda{|e| e == "content2"})
p data.high  # => [{:title=>"title2", :content=>"content2"}]

if you want to omit data,

data.omit(:title, lambda{|e| e == "fake"})
p data   # => [{:title=>"title1", :content=>"content1"}, {:title=>"title2", :content=>"content2"}]
p data.garbage   # => [{:title=>"fake", :content=>"fake content"}]

if you want to change data,

data.filter(:title, lambda do |e|
              e.gsub(/title/, "change") || e
            end)
p data   # => [{:title=>"change1", :content=>"content1"}, {:title=>"change2", :content=>"content2"}]

if you want NOT to make attributes of data changed,

data.bind([:title, :content])
data.push({test: "test"})}   # => raise error

And Screening::Data inherits Array class.So you can use it like Array!

TODO

1. Complex classification(ex.Proc with many symbol.).
2. If you omit elements, they are moved to "garbage".
3. Binding attributes.
4. Version management.
5. Huge data.
6. Output various files(csv, xls and others).
