		$manualLevel = `[]`
	)

Constructor.

Parameters

Language	$langobj
string	$maincode	The main language code of this language
array	$variants	The supported variants of this language
array	$variantfallbacks	The fallback language of each variant
array	$flags	Defining the custom strings that maps to the flags

Member Function Documentation

LanguageConverter::applyManualConv ( $convRule )

protected

Apply manual conversion rules.

Parameters

ConverterRule $convRule

Definition at line 488 of file LanguageConverter.php.

References $from, as, and validateVariant().

Referenced by recursiveConvertRule().

LanguageConverter::autoConvert	(	$text,
		$toVariant = `false`
	)

Dictionary-based conversion.

This function would not parse the conversion rules. If you want to parse rules, try to use convert() or convertTo().

Parameters

string	$text	The text to be converted
bool \| string	$toVariant	The target language code

Returns: string The converted text

LanguageConverter::autoConvertToAllVariants ( $text )

Call translate() to convert text to all valid variants.

Parameters

string $text The text to be converted

Returns: array Variant => converted text

Definition at line 472 of file LanguageConverter.php.

References $ret, as, loadTables(), and translate().

Referenced by findVariantLink().

LanguageConverter::convert ( $text )

Convert text to different variants of a language.

The automatic conversion is done in autoConvert(). Here we parse the text marked with -{}-, which specifies special conversions of the text that can not be accomplished in autoConvert().

Syntax of the markup: -{code1:text1;code2:text2;...}- or -{flags|code1:text1;code2:text2;...}- or -{text}- in which case no conversion should take place for text

Parameters

string $text Text to be converted

Returns: string Converted text

Definition at line 600 of file LanguageConverter.php.

References convertTo(), and getPreferredVariant().

LanguageConverter::convertCategoryKey ( $key )

Convert the sorting key for category links.

This should make different keys that are variants of each other map to the same key.

Parameters

string $key

Returns: string

Definition at line 1054 of file LanguageConverter.php.

LanguageConverter::convertNamespace	(	$index,
		$variant = `null`
	)

Get the namespace display name in the preferred variant.

Parameters

int	$index	Namespace id
string \| null	$variant	Variant code or null for preferred variant

Returns: string Namespace name for display

Definition at line 544 of file LanguageConverter.php.

References $cache, CACHE_NONE, getPreferredVariant(), ObjectCache\newAccelerator(), NS_MAIN, translate(), wfMemcKey(), and wfMessage().

LanguageConverter::convertTitle ( $title )

Auto convert a Title object to a readable string in the preferred variant.

Parameters

Title $title A object of Title

Returns: string Converted title text

Definition at line 525 of file LanguageConverter.php.

References $title, convertNamespace(), getPreferredVariant(), NS_MAIN, and translate().

LanguageConverter::convertTo	(	$text,
		$variant
	)

Same as convert() except a extra parameter to custom variant.

Parameters

string	$text	Text to be converted
string	$variant	The target variant code

Returns: string Converted text

LanguageConverter::findVariantLink	(	&	$link,
		&	$nt,
			$ignoreOtherCond = `false`
	)

If a language supports multiple variants, it is possible that non-existing link in one variant actually exists in another variant.

This function tries to find it. See e.g. LanguageZh.php The input parameters may be modified upon return

Parameters

string	&$link	The name of the link
Title	&$nt	The title object of the link
bool	$ignoreOtherCond	To disable other conditions when we need to transclude a template or update a category's link

LanguageConverter::getConvRuleTitle ( )

Get the title produced by the conversion rule.

Returns: string The converted title text

Definition at line 150 of file LanguageConverter.php.

This function would not be affected by user's settings

Returns: string The default variant code

LanguageConverter::getVariantFallbacks ( $variant )

In case some variant is not defined in the markup, we need to have some fallback.

For example, in zh, normally people will define zh-hans and zh-hant, but less so for zh-sg or zh-hk. when zh-sg is preferred but not defined, we will pick zh-hans in this case. Right now this is only used by zh.

Parameters

string $variant The language code of the variant

Returns: string|array The code of the fallback language or the main code if there is no fallback
