Alter the information parsed from module and theme .info files

This hook is invoked in _system_rebuild_module_data() and in _system_rebuild_theme_data(). A module may implement this hook in order to add to or alter the data generated by reading the .info file with drupal_parse_info_file().


$info: The .info file contents, passed by reference so that it can be altered.

$file: Full information about the module or theme, including $file->name, and $file->filename

$type: Either 'module' or 'theme', depending on the type of .info file that was passed.

Upchuk’s picture

This hook is invoked in _system_rebuild_module_data() and in _system_rebuild_theme_data().

Since this is the case, this hook will be invoked by the update.php before modules are updated. So if you are implementing this hook, keep this in mind.
