hook_theme_registry_alter(&$theme_registry)

Alter the theme registry information returned from hook_theme().

The theme registry stores information about all available theme hooks, including which callback functions those hooks will call when triggered, what template files are exposed by these hooks, and so on.

Note that this hook is only executed as the theme cache is re-built. Changes here will not be visible until the next cache clear.

The $theme_registry array is keyed by theme hook name, and contains the information returned from hook_theme(), as well as additional properties added by _theme_process_registry().

For example:

<?php

$theme_registry['user_profile'] = array(
'arguments' => array(
'account' => NULL,
),
'template' => 'modules/user/user-profile',
'file' => 'modules/user/user.pages.inc',
'type' => 'module',
'theme path' => 'modules/user',
'theme paths' => array(
0 => 'modules/user',
),
'preprocess functions' => array(
0 => 'template_preprocess',
1 => 'template_preprocess_user_profile',
),
)
);

?>
