OptInt PmWiki : PmWiki / I18n Variables

This page describes the variables used by PmWiki for Internationalizations (i18n).

$VarPagesFmt: An array which contains the PageNames where you can find lists (trails) of pages containing variable definitions. To be modified when documentation is not in english. See scripts/vardoc.php.
$XL: An array (hash) which contains pairs of language identifiers and translation hashes. Each translation hash maps a given lookup key (or phrase) into a corresponding text string for the given language. Thus, it is essentially a multi-lingual dictionary used for phrase translation. It is also used for handling user preference mappings. Thus, the 'e_row' value that one finds on the Site.Preferences page is loaded into $XL during preference processing.
$XLLangs: An array that contains the names of the currently active language definitions. Only dictionaries in $XL that are named in $XLLangs are used by the $[...] markup when performing a translation.
