Member Function Documentation

◆ addLinksFromRepository()

Wikibase\Client\Hooks\LangLinkHandler::addLinksFromRepository	(	Title	$title,
		ParserOutput	$out
	)

Look up sitelinks for the given title on the repository and add them to the ParserOutput object, taking into account any applicable configuration and any use of the {{#noexternallanglinks}} function on the page.

The language links are not sorted, call sortLanguageLinks() to do that.

Parameters

Title	$title	The page's title
ParserOutput	$out	Parsed representation of the page

◆ addLinksToOutput()

Wikibase\Client\Hooks\LangLinkHandler::addLinksToOutput	(	array	$links,
		ParserOutput	$out
	)

private

Adds the given SiteLinks to the given ParserOutput.

Parameters

SiteLink[]	$links
ParserOutput	$out

◆ filterRepoLinksByGroup()

Wikibase\Client\Hooks\LangLinkHandler::filterRepoLinksByGroup	(	array	$repoLinks,
		array	$allowedGroups
	)

Filters the given list of links by site group: Any links pointing to a site that is not in $allowedGroups will be removed.

Parameters

array	$repoLinks	An array that uses global site IDs as keys.
string[]	$allowedGroups	A list of allowed site groups

Returns: array A filtered copy of $repoLinks, retaining only the links pointing to a site in an allowed group.

◆ getEffectiveRepoLinks()

Wikibase\Client\Hooks\LangLinkHandler::getEffectiveRepoLinks	(	Title	$title,
		ParserOutput	$out
	)

Look up sitelinks for the given title on the repository and filter them taking into account any applicable configuration and any use of the {{#noexternallanglinks}} function on the page.

The result is an associative array of links that should be added to the current page, excluding any target sites for which there already is a link on the page.

Parameters

Title	$title	The page's title
ParserOutput	$out	Parsed representation of the page

Returns: SiteLink[] An associative array, using site IDs for keys and the target pages in the respective languages as the associated value.

◆ getInterwikiCodeFromSite()

Wikibase\Client\Hooks\LangLinkHandler::getInterwikiCodeFromSite ( Site $site )

Extracts the local interwiki code, which in case of the wikimedia site groups, is always the global id's prefix.

@fixme put somewhere more sane and use site identifiers data, so that this works in non-wikimedia cases where the assumption is not true.

Parameters

Site $site

Returns: string

◆ getNoExternalLangLinks()

Wikibase\Client\Hooks\LangLinkHandler::getNoExternalLangLinks ( ParserOutput $out )

Get the noexternallanglinks page property from the ParserOutput, which is set by the {{#noexternallanglinks}} parser function.

See also: NoLangLinkHandler::getNoExternalLangLinks

Parameters

ParserOutput $out

Returns: string[] A list of language codes, identifying which repository links to ignore. Empty if {{#noexternallanglinks}} was not used on the page.

◆ indexLinksByInterwiki()

Wikibase\Client\Hooks\LangLinkHandler::indexLinksByInterwiki ( array $links )

private

Parameters

SiteLink[] $links

Returns: SiteLink[] The SiteLinks in $links, indexed by interwiki prefix.

◆ localLinksToArray()

Wikibase\Client\Hooks\LangLinkHandler::localLinksToArray ( array $flatLinks )

private

Converts a list of interwiki links into an associative array that maps global site IDs to the respective target pages on the designated wikis.

Parameters

string[] $flatLinks

Returns: string[] An associative array, using site IDs for keys and the target pages on the respective wiki as the associated value.

◆ suppressRepoLinks()

Wikibase\Client\Hooks\LangLinkHandler::suppressRepoLinks	(	ParserOutput	$out,
		array	$repoLinks
	)

Returns a filtered version of $repoLinks, containing only links that should be considered for combining with the local inter-language links.

This takes into account the {{#noexternallanglinks}} parser function, and also removed any link to this wiki itself.

This function does not remove links to wikis for which there is already an inter-language link defined in the local wikitext. This is done later by getEffectiveRepoLinks().

Parameters

ParserOutput	$out
array	$repoLinks	An array that uses global site IDs as keys.

Returns: SiteLink[] A filtered copy of $repoLinks, with any inappropriate entries removed.

◆ useRepoLinks()

Wikibase\Client\Hooks\LangLinkHandler::useRepoLinks	(	Title	$title,
		ParserOutput	$out
	)

Checks if a page have interwiki links from Wikidata repo? Disabled for a page when either:

Wikidata not enabled for namespace
nel parser function = * (suppress all repo links)

Parameters

Title	$title
ParserOutput	$out

Returns: bool
