.info files are now .info.yml files

All of our old .info files have been converted to YAML and the old .info parser has been removed. The new parser is the Symfony YAML component. The new file extension is .info.yml. This applies to modules, themes, and profiles.

Online documentation: Let Drupal 8 know about your module with an .info.yml file.

Overview

Syntax

• For the most part, change all = to :.
• For arrays (e.g. dependencies[] = node), use the following format in drupal 8:
  

  dependencies:
    - drupal:node
  

Note the use of the {project}:{module} format now required for core and contrib modules.

• In drupal 7 we use ; for Comments And now in drupal 8 we use # for Comments.

More information on the YAML file format

New required 'type' key

A new type key is now required with values that indicate the type of extension. Use module, theme or profile. For example:

type: module

Remove files[] entries

Remove any files[] entries. Classes are now autoloaded using a separate mechanism: PSR-4 compatible class loader in core

Convert configure links to route names

In Drupal 8, specify the administrative configuration link using the route name instead of the system path.

Drupal 7

configure = admin/config/system/actions

Drupal 8

configure: action.admin

More information on the new routing system: hook_menu() has been replaced by new routing system
