NAME

       Template::Multilingual - Multilingual templates for Template Toolkit

SYNOPSIS

       This subclass of Template Toolkit's "Template" class supports multilingual templates: templates that
       contain text in several languages.

           <t>
             <en>Hello!</en>
             <fr>Bonjour !</fr>
           </t>

       Specify the language to use when processing a template:

           use Template::Multilingual;

           my $template = Template::Multilingual->new();
           $template->language('en');
           $template->process('example.ttml');

       You can also provide the name of the template variable that will hold the language:

           my $template = Template::Multilingual->new(LANGUAGE_VAR => 'foo');
           $template->process('example.ttml', { foo => 'en' });

METHODS

   new(\%params)
       The new() constructor creates and returns a reference to a new template object. A reference to a hash may
       be supplied as a parameter to provide configuration values.

       Configuration values are all valid "Template" superclass options, and one specific to this class:

       LANGUAGE_VAR
           The LANGUAGE_VAR option can be used to set the name of the template variable which contains the
           current language.

             my $parser = Template::Multilingual->new({
                LANGUAGE_VAR => 'global.language',
             });

           If this option is set, your code is responsible for setting the variable's value to the current
           language when processing the template. Calling "language()" will have no effect.

           If this option is not set, it defaults to language.

   language($lcode)
       Specify the language to be used when processing the template. Any string that matches "\w+" is fine, but
       we suggest sticking to ISO-639 which provides 2-letter codes for common languages and 3-letter codes for
       many others.

   process
       Used exactly as the original Template Toolkit "process" method.  Be sure to call "language" before
       calling "process".

LANGUAGE SUBTAG HANDLING

       This module supports language subtags to express variants, e.g. "en_US" or "en-US".  Here are the rules
       used for language matching:

       •   Exact match: the current language is found in the template

             language    template                              output
             fr          <fr>foo</fr><fr_CA>bar</fr_CA>        foo
             fr_CA       <fr>foo</fr><fr_CA>bar</fr_CA>        bar

       •   Fallback to the primary language

             language    template                              output
             fr_CA       <fr>foo</fr><fr_BE>bar</fr_BE>        foo

       •   Fallback to first (in alphabetical order) other variant of the primary language

             language    template                              output
             fr          <fr_FR>foo</fr_FR><fr_BE>bar</fr_BE>  bar
             fr_CA       <fr_FR>foo</fr_FR><fr_BE>bar</fr_BE>  bar

BUGS

       Multilingual text sections cannot be used inside TT directives.  The following is illegal and will
       trigger a TT syntax error:

           [% title = "<t><fr>Bonjour</fr><en>Hello</en></t>" %]

       Use this instead:

           [% title = BLOCK %]<t><fr>Bonjour</fr><en>Hello</en></t>[% END %]

       The TAG_STYLE, START_TAG and END_TAG directives are supported, but the TAGS directive is not.

       Please report any bugs or feature requests to "bug-template-multilingual@rt.cpan.org", or through the web
       interface at <http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Template-Multilingual>.  I will be notified,
       and then you'll automatically be notified of progress on your bug as I make changes.

       If you are already using your own "Template" subclass, you may find it easier to use
       Template::Multilingual::Parser instead.
