A Javascript (function) interpreter for Ruby.

Examples¶ ↑

Doily was basically designed to support CouchDB views. So, you can do stuff like this:

class CouchDBView
  def map(function, documents)
    function = Doily(function).delegate(self)

    @results = []
    documents.each { |doc| function.call(doc) }
    @results
  end

  def emit(key, value)
    @results.push(:key => key, :value => value)
  end
end

map_function = <<-END
  function(doc) {
    if (doc.chef_type == 'node') {
      emit(doc.name, doc);
    }
  }
END

CouchDBView.new.map(map_function, Document.all)
