¿Drupal 8? #2146779: Port Variable to Drupal 8

Why?

• So other modules can know about your module's variables and they can be translated, exported, used in views, etc.
• You'll get automatic variable edit forms, tokens, access control and uninstall for free
• Your module's variables will be allowed for Variable Realms being able to get values for each language (Internationalization) or Domain (Variable Domain)

A module which runs the Drupal cron operation using normal browser/page requests instead of having to set up a crontab to request the cron.php script. The module inserts a small amount of JavaScript on each page of your site that when a certain amount of time has passed since the last cron run, calls an AJAX request to run the cron tasks. Your users should not notice any kind of delay or disruption when viewing your site. However, this approach requires that your site gets regular traffic/visitors in order to trigger the cron request.

Recipe is a module for sharing cooking recipes. It provides a Recipe content type, an Ingredient entity type, an Ingredient reference field, and custom Views display styles for recipe sharing and printing.

Checks spelling for Text Review's text sources, such as content and comments.

This module enables you to create arbitrary Workflows, and assign them to Entities.

Workflows are made up of workflow states. Transitions between states can be allowed per role. For example, a workflow with the states Draft, Review, and Published could be assigned to the Story node type. Only users with role 'chief editor' can set Stories to the published state.
You can set up the Workflow to alter states from form, page, comment, a special block, and a special workflow tab.
Additionally, the submodule Workflow Access allows you to manage view/edit/delete permissions for content types per User role and Workflow state.
