History

Version 0.1.0  Beta Version
Version 0.1.1  Readme is fixed.

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

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