---+!! ForUserLanguagesPlugin
 ForUserLanguagesPlugin used to insert full or partial translations and keep them in the original topic. 
%TOC% 
---++ Why to keep translation in the same topic?
 There are [[http://twiki.org/cgi-bin/view/Codev/LocalizationFramework][two official ways]] of TWiki internationalisation: [[http://twiki.org/cgi-bin/view/Codev/TranslationSupport][Support for translated topics]] and [[http://twiki.org/cgi-bin/view/Codev/UserInterfaceInternationalisation][Support for translated strings in code]]. Nevertheless, there are valuable reasons to keep several translations in the same topic in sites where to keep information up-to-date is more important than to provide full translation: 
   * It is much more easy to check and keep consistency when update: 
      * Code fragment, image or some other language independent content will be rendered from the unique source fragment and it will be immediately automatically updated in all needed languages simultaneously. 
      * Fragments deletion and moving will also be easily done in all translations together 
      * User see the translations while editing and can replace or mark outdated some translations of editing paragraph. 
   * Sometimes possibility to keep partial translations in original language (i.e. leave in original language some less actual notes, unnecessary explanations, examples, comments etc.) may save a lot of time for a really usefull work. 

---++ Syntax Rules
 There are predefined translation switch to separate contents for different user language, and they are fully customisable. 
---+++ Predefined translation switch
 Plugin introduce the one new variable %FORUSERLANGUAGES{}%.

The variable must have an argument either
   * the comma separated list of user language codes or 
   * the same list prepended with negation exclamation mark '!'. The text between two %FORUSERLANGUAGES{}% will disappear if and only if current user %LANGUAGE% is not in list or it is in list after the exclamation mark. 

---++++ Example

=%FORUSERLANGUAGES{ru,ua,bg}%=

_The part of the topic in Russian_ (for users who prefer Cyrillic text)

=%FORUSERLANGUAGES{!ru,ua,bg}%=

_The same part of the topic in English_ (translation for other users)

=%FORUSERLANGUAGES{!}%=

Language independent or untranslated data comes here.

=%FORUSERLANGUAGES{!ru,ua,bg}%=

_The next part of the topic in English again_ (only for non-Cyrillic users)

---+++ Using shortcut aliases example

Compare the code
<verbatim>
<Cyr> Russian version of the text fragment <Lat> English version of the same 
fragment <Any> Common part <Cyr> Russian <Lat> English <Any> version of the next fragment ...
</verbatim> and the rendering result:

<Cyr> Russian version of the text fragment <Lat> English version of the same fragment <Any> Common part <Cyr> Russian <Lat> English <Any> version of the next fragment ...

---++ Plugin Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write ==%<plugin>_<setting>%==, i.e. ==%POLYGLOTPLUGIN_SHORTDESCRIPTION%==

   * One line description, is shown in the %TWIKIWEB%.TextFormattingRules topic: 
      * Set SHORTDESCRIPTION = used to insert full or partial translations and keep them in original topic.     

   * Shortcut aliases for any translation switches may be defined via the variable FORUSERLANGUAGESALIASES, which contains the semicolon separated list of aliases. Example above use the following setting in Main.TwikiPreferences 
<verbatim>
      * Set FORUSERLANGUAGESALIASES = <ru> = ru,ua,bg; <en> = !ru,ua,bg; <any> = !
</verbatim>
   * Debug plugin: (See output in =data/debug.txt=) 
      * Set DEBUG = 0
