Gem with utilities used by Unity team

• Utils:

  • Retrier - Restarting passed block.

    Unity::Utils::Retrier.call { 5 / 0 }

  • ThreadPool - Working with multithreading.

    result = []
    pool = Unity::Utils::ThreadPool.new(50)
    
    10.times { |n| pool.schedule { result << n * n } }
    
    pool.run!

  • UrlFormatter - Formats url.

    formatter = ::Unity::Utils::UrlFormatter.new('blog/post/nykotyn-bez-syharet-hde-on-soderzytsia/')
    formatter.trailing_slash(enabled: false).build #=> "blog/post/nykotyn-bez-syharet-hde-on-soderzytsia"
    formatter.params({'erid' => 'test'}).build #=> "blog/post/nykotyn-bez-syharet-hde-on-soderzytsia?erid=test"

  • UrlValidator - Validates url.

    response = UrlValidator.new('ftp://motor.ru/reports/videoparis.htm').call
    response.valid? #=> false
    response.errors #=> ['Ссылка должна начинаться с http(s)']

• Modules:

  • CliModeable - Wrapper over the ruby-progressbar.

    elements = (1..10).to_a
    @cli_mode  = true
    
    init_progressbar(elements.count)
    
    elements.each do |element|
    incr_progressbar
    
    # do something and look on great progress bar :)
    end

  • EntitiesLogDump - Module for service objects do dump entities.

      dump_entities(Topic.first, attributes: [:id, :headline]) # => [{ "id" => 1, "headline" => "foo" }, { "id" => 2, "headline" => "bar" }]
      dump_entities(Topic.first(2), attributes: [:id, :headline]) #=> { "id" => 1, "headline" => "foo" }

    Will work both with ApplicationRecord or Mongoid::Document models.

  • FlexibleBoolean - Concern to make easier work with virtual boolean attributes.

    class MyKlass
      include IsReactable
    
      flexible_boolean :is_reactable
    
      attr_reader :is_reactable
    
      def intiailize(is_reactable)
        @is_reactable = is_reactable
      end
    end
    MyKlass.new(true).is_reactable  # => true
    MyKlass.new(nil).is_reactable   # => false

  • Loggable - Wrapper over logger.

    @log_file = 'some_file.log'
    @logger = Logger.new(@log_file)
    
    clean_logfile
    
    begin
        5 / 0
    rescue StandardError => e
        pretty_e = exception_to_array(e)
        logger.error(pretty_e)
    end

• Rake tasks:

  • unity:rspec - rspec with custom report format: collapses pending tests and adds some analytics.

    bundle exec rake unity:rspec
    bundle exec rake unity:rspec\['spec/queries'\]
    bundle exec rake unity:rspec\['spec/{jobs\,services}/'\]
    bundle exec rake unity:rspec\['spec/ --exclude-pattern "spec/{models\,requests}/**/*_spec.rb"'\]
