Detailed Description

Base class for multi-variant language conversion.

Definition at line 41 of file LanguageConverter.php.

Constructor & Destructor Documentation

◆ __construct()

LanguageConverter::__construct ( $langobj)

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$textThe text to be converted
string | false$toVariantThe 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$textThe 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$textText to be converted, already html escaped.
Returns
string Converted text (html)

Implements ILanguageConverter.

Definition at line 876 of file LanguageConverter.php.

◆ convertCategoryKey()

LanguageConverter::convertCategoryKey ( $key)
