Data assignment

You can simply pass data to any object or template with the configuration file: packages/Acme/etc/config.php

<?php

$config = [
    Core_Block::TYPE => [
        'default' => [
            'scope' => 'I\'m available in all blocks of the "Acme" package',
        ],
        'banner' => [
            'scope' => 'I\'m available in the block "banner" of the "Acme" package',
        ],
    ],
];

The data will be available in class or template file with the getData method or the magic getter:

<?php

$this->getData('scope');
// or
$this->getScope();

Use global configuration file to set data to packages and objects according the environment: etc/config.{MW_ENVIRONMENT}.php

<?php

$config = [
    'default' => [ // All packages
        'default' => [
            'default' => [
                 'scope' => 'I\'m available everywhere in all packages for the current environment',
            ],
        ],
        Core_Page::TYPE => [
            'default' => [
                'scope' => 'I\'m available in all pages of all packages for the current environment',
            ],
        ],
        Core_Block::TYPE => [
            'banner' => [
                'scope' => 'I\'m available in the block "banner" of all packages for the current environment',
            ],
        ],
    ],
];

A "default" value will be overridden by the specified package, type or identifier.

Overload hierarchy:

default.default.default
default.default.{identifier}
default.{type}.default
default.{type}.{identifier}
{package}.default.default
{package}.default.{identifier}
{package}.{type}.default
{package}.{type}.{identifier}
