It is possible to dynamically inject variables in content view templates by listening to the ezpublish.pre_content_view event.
The event listener method receives an eZ\Publish\Core\MVC\Symfony\Event\PreContentViewEvent object
Example
The following example will inject foo and osTypes variables in all content view templates.

<?php

use eZ\Publish\Core\MVC\Symfony\Event\PreContentViewEvent;
class PreContentViewListener
{
public function onPreContentView( PreContentViewEvent $event )
{
// Get content view object and inject whatever no need.
// You may add some custom business logic here.
$contentView = $event->getContentView();
$contentView->addParameters(
array(
'foo' => 'bar',
'osTypes' => array( 'osx', 'linux', 'win' )
)
);
}
