NAME

Template::Multilingual::Parser - Multilingual template parser

SYNOPSIS

  use Template;
  use Template::Multilingual::Parser;

  my $parser = Template::Multilingual::Parser->new();
  my $template = Template->new(PARSER => $parser);
  $template->process('example.ttml', { language => 'en'});

DESCRIPTION

This subclass of Template Toolkit's Template::Parser parses multilingual templates: templates that contain text in several languages.

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

Use this module directly if you have subclassed Template, otherwise you may find it easier to use Template::Multilingual.

Language codes can be any string that matches \w+, but we suggest sticking to ISO-639 which provides 2-letter codes for common languages and 3-letter codes for many others.

METHODS

new(\%params)

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

Parser objects are typically provided as the PARSER option to the Template constructor.

Configuration values are all valid Template::Parser 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. Defaults to language.

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

You will need to set this variable with the current language value at request time, usually in your Template subclass' process() method.

parse($text)

parse() is called by the Template Toolkit. It parses multilingual sections from the input text and translates them to Template Toolkit directives. The result is then passed to the Template::Parser superclass.

sections

Returns a reference to an array of tokenized sections. Each section is a reference to hash with either a nolang key or a lang key.

A nolang key denotes text outside of any multilingual sections. The value is the text itself.

A lang key denotes text inside a multilingual section. The value is a reference to a hash, whose keys are language codes and values the corresponding text. For example, the following multilingual template:

foo <t><fr>bonjour</fr><en>Hello</en></t> bar

will parse to the following sections:

[ { nolang => 'foo ' },
  {   lang => { fr => 'bonjour', en => 'hello' } },
  { nolang => ' 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.
