Multilingual templates for template toolkit

Usage

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 "[email protected]", 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.
