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.
