◆ __construct()

LanguageConverter::__construct ( $langobj )

Parameters

Language | StubUserLang $langobj

Reimplemented in CrhConverter.

Definition at line 115 of file LanguageConverter.php.

Member Function Documentation

◆ applyManualConv()

LanguageConverter::applyManualConv ( ConverterRule $convRule )

protected

Apply manual conversion rules.

Parameters

ConverterRule $convRule

Definition at line 734 of file LanguageConverter.php.

References ConverterRule\getConvTable(), ConverterRule\getRulesAction(), and ConverterRule\getTitle().

◆ autoConvert()

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
string \| false	$toVariant	The target language code

Returns: string The converted text

Implements ILanguageConverter.

Definition at line 542 of file LanguageConverter.php.

References Parser\MARKER_PREFIX.

◆ autoConvertToAllVariants()

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

Implements ILanguageConverter.

Definition at line 718 of file LanguageConverter.php.

◆ convert()

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

Warning: Glossary state is maintained between calls. Never feed this method input that hasn't properly been escaped as it may result in an XSS in subsequent calls, even if those subsequent calls properly escape things.

Parameters

string $text Text to be converted, already html escaped.

Returns: string Converted text (html)

Implements ILanguageConverter.

Definition at line 876 of file LanguageConverter.php.
