Feature: Data Sources
  In order to use external data in my blog
  As a blog's user
  I want to use data sources in my site

  Scenario: Use JSON data source
    Given I have a "_config.yml" file with content:
      """
      data_sources:
        - name: jsonip
          url: 'http://jsonip.com/'
          type: json
      """

    And I have an "index.html" page that contains "{{ site.jsonip.ip }}"
    When I run monad
    Then the "_site/index.html" file should exist
    And I should see "\d+\.\d+\.\d+\.\d+" in "_site/index.html"

  Scenario: Use YAML data source
    Given I have a "_config.yml" file with content:
      """
      data_sources:
        - name: languages
          path: _data/languages.yaml
          type: yaml
      """

    And I have an "index.html" page that contains "{% for language in site.languages %}{{language}}{% endfor %}"
    And I have a _data directory
    And I have a "_data/languages.yaml" file that contains "[java, ruby]"
    When I run monad
    Then the "_site/index.html" file should exist
    And I should see "java" in "_site/index.html"
    And I should see "ruby" in "_site/index.html"

  Scenario: Support custom data source driver
    Given I have a "_config.yml" file with content:
      """
      data_sources:
        - name: languages
          path: _data/languages.json
          type: json_fs
      """

    And I have a _plugins directory
    And I have a "_plugins/json_fs_driver.rb" file with content:
      """
      require 'json'

      module Monad
        module Drivers
          class JsonFsDriver
            def initialize(options)
              @path = options['path']
            end

            def load
              JSON.parse(File.read(@path))
            end
          end
        end
      end
      """

    And I have a _data directory
    And I have a "_data/languages.json" file with content:
      """
      ["java", "ruby"]
      """
    And I have an "index.html" page that contains "{% for language in site.languages %}{{language}}{% endfor %}"
    When I run monad
    Then the "_site/index.html" file should exist
    And I should see "java" in "_site/index.html"
    And I should see "ruby" in "_site/index.html"
