Manual:LocalSettings.php snippets

Here are some snippets you can add to LocalSettings.php to accomplish various tasks. A "snippet" is usually a short hook function, typically less than 20 lines, such that it wouldn't be worth bothering to implement it as an extension.

Snippets

SecretSpies

You may wish to enable some users to view deleted articles without making it evident to everyone who these users are. This would be implemented by:

$wgHooks['UserGetRights'][] = 'secretSpies';
$wgSecretSpies = array( // Users allowed to view deleted history entries and deleted revision text
	'AldrichAmes',
	'RobertHanssen'
);

// Allow secret spies to view deleted history entries and deleted revision text
function secretSpies( $user, &$aRights ) {
	global $wgSecretSpies;
	if ( in_array( $user->getName(), $wgSecretSpies ) ) {
		$aRights[] = 'deletedhistory';
		$aRights[] = 'deletedtext';
	}
	return true;
}

Twitter-optimized recent changes feed

(See phabricator:T132840)

$wgHooks['ChangesListSpecialPageQuery'][] = 'onChangesListSpecialPageQuery';
function onChangesListSpecialPageQuery( $name, &$tables, &$fields, &$conds, &$query_options, &$join_conds, $opts ) {
	global $wgTitle;
	if (
	    $wgTitle != 'Special:Badtitle/dummy title for API calls set in api.php'
	    || $name != 'Recentchanges'
	) {
		return true;
	}
	if ( !in_array( 'page', $tables ) ) {
		$tables[] = 'page';

	}
	if ( !in_array( 'page_latest', $fields ) ) {

	if ( !in_array( 'page_is_redirect', $fields ) ) {

	}
	if ( !isset( $join_conds['page'] ) ) {
		$join_conds['page'] = array( 'LEFT JOIN', 'rc_cur_id=page_id' );
	}
	if ( !isset( $conds['page_is_redirect'] ) ) {
		$conds['page_is_redirect'] = 0;
	}
	if ( !isset( $conds['rc_patrolled'] ) ) {
		$conds['rc_patrolled'] = 1;
	}
	if ( !isset( $conds['rc_new'] ) ) {
		$conds['rc_new'] = 1;
	}
	if ( !isset( $conds['rc_namespace'] ) ) {
		$conds['rc_namespace'] = 0;
