Juknife

Build Status

A Ruby library for Web scraping. It allows to describe scraping nodes and text structurally and declaratively.

For example, scraping on Google search can be written as follows:

class GoogleSearchAgent < Juknife::Agent
  request do
    get 'https://www.google.co.jp/search'
    user_agent 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)'
    query do
      {
        q: params[:query]
      }
    end
  end

  scraping do
    items :results, '#ires .g' do
      item :title, 'h3'
      item :url, '.kv > cite'
      item :description, '.st'
    end
  end
end

agent = GoogleSearchAgent.new
agent.scrape(query: 'test')
# =>
# {:results=>
#   [
#     {:title=>"testの意味・用例|英辞郎 on the WEB:アルク",
#      :url=>"https://eow.alc.co.jp/search?q=test",
#      :description=>
#       "test 【1自動】 試験[検査]を受ける 《医・化学》検査[分析]を行う 〔試験で... - アルクがお\n" +
#       "届けする進化するオンライン英和・和英辞書データベース。一般的な単語や連語から、\n" +
#       "イディオム、専門用語、スラングまで幅広く収録。"}
#     }
#   ]
# }

Usage

[TODO]

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
